Background

According to the World Health Organization (WHO), the world faces numerous challenges, including disparities in the availability and quality of eyecare services for prevention, treatment, and rehabilitation. No previous study in Afghanistan has ever examined both mental and physical component of quality of life among patients with eye diseases. Therefore, present study examined the quality of life and its relationship with socio-demographic characteristics among this vulnerable group.

Methods

A cross-sectional survey was administered from January 2022 to April 2022. Data were collected from participants with eye diseases (N = 617) in the Herat province of Afghanistan.

Results

Of the 617 participants, 63.4% had poor physical quality of life and 14.9% had poor mental quality of life. Among participants, the main variables associated with physical and mental quality of life were age, gender, marital status, education level, monthly income, occupation, using social media, and a traumatic event occurring during the past month. Multiple regression analysis indicated that poor physical quality of life was significantly associated with with being above 54 years old (adjusted odds ratio [AOR] = 1.15, p = .0048), being female (AOR = 3.58. p < 0.01), being illiterate (AOR = 3.31, p = 0.01), being unemployed (AOR = 1.93, p = 0.04), and experiencing a traumatic event during the past month (AOR = 2.06, p = 0.02). Poor mental quality of life was associated occupational status (being unemployed) (AOR = 3.62, p = 0.05), and experiencing a traumatic event in the past month (AOR = 3.49, p < 0.01).

Conclusion

The present study provides a novel contribution to the field eye diseases and quality of life especially in relation to Afghanistan where there has been very little research in this area. The results indicate that public health authorities in Afghanistan should implement policies to raise awareness regarding the quality of life of patients with eye diseases as well as formulating strategies to help improve it.

Eye patients

According to the World Health Organization (WHO), the world faces numerous challenges, including disparities in the availability and quality of eyecare services for prevention, treatment, and rehabilitation [1]. Eye problems include a wide range of disorders and diseases including refractive errors, age-related macular degeneration, cataracts, diabetic retinopathy, glaucoma, amblyopia, and strabismus [2]. The WHO reports that 2.2 billion individuals worldwide suffer from vision impairment [1]. A study concerning the impact of blindness and moderate and severe vision impairment on the global economy reports an estimate of a 30.2% employment reduction among employees with vision loss. Moreover, the global annual cost of this reduction in employment is estimated to be $410.7 billion (US) [3].

According to the Lancet Global Health Commission on Global Eye Health, it is estimated that there will be 895 million individuals worldwide with vision impairment by 2050, of whom 61 million will be blind, due to population aging, growth, and urbanization. Therefore, interventions in eyecare, which are known to be the most economical in the entire healthcare system, are necessary to be prioritized through equitable and inclusive service [4]. Vision impairment significantly lowers the quality of life among adults by lowering productivity and workforce participation rates, while increasing anxiety and depression levels [5].

Quality of life is a term that refers to the well-being of a population or an individual in terms of both positive and negative aspects of their existence during a specific period [6]. A significant indicator of how eye health affects individuals’ everyday lives, general well-being, and visual function is quality of life, such that vision impairment and eye illness have been linked to higher rates of mortality and lower quality of life [7].

According to the findings of a large-scale study conducted in Germany examining vision-related quality of life in healthcare research (n = 11,941), both eyes (the better-seeing eye and the worse-seeing eye) should be evaluated, since only including the better-seeing eye might result in an underestimated effect of visual impairment on vision-related quality of life. [8]. In another study in Northwest Ethiopia, it was reported that there was a low quality of life among 49.2% of patients with vision impairment (n = 484) [9]. Several factors demonstrated a statistically significant association with this diminished vision-related quality of life. These factors included being over 75 years old, residing in rural areas, experiencing severe visual impairment or blindness, and having a history of visual impairment lasting longer than 3 years [9]. Enoch et al. conducted a cross-sectional web-based survey where participants (n = 250) rated their five senses (sight, hearing, touch, smell, and taste) and other personal variables (balance, temperature, pain) from most to least important. Results showed that the highest-ranked sense was sight. Moreover, participants reported that they would prefer living with 4.6 years of perfect health compared to 10 years with total blindness [10].

In relation to gender, a mini review of multiple studies reported that there were gender differences in the prevalence of ocular diseases. Some eye diseases including dry eye syndrome, cataracts (with increasing age), angle-closure glaucoma, and primary vascular dysregulation syndrome disproportionately affect women more than men [11]. Among children, those with strabismus experience a poorer quality of life compared to children with normal sight [12]. According to a study conducted in schools for the blind in Northeast India, 85.5% of the children (n = 515) experienced a low quality of life [13].

In relation to emerging adults, the results of another study showed that those aged 18–25 years old experiencing vision problems (n = 172) had significantly poor quality of life (daily activities, work, study, etc.) compared to the general population with three chronic diseases. However, the results also showed that vision impairment only moderately affected some areas of quality of life in youth [14]. Results of a study conducted in Tehran (Iran) reported that vision-related quality of life among older people (n = 566) was significantly associated with physical and socio-cultural quality as well as access to eyecare [15].

The results of a cohort study on glaucoma patients (n = 1728) and their socioeconomic status found that when the development of visual impairment occurred before being diagnosed with glaucoma, patients with lower income experienced higher visual impairment in comparison to patients with higher income [16]. Another study evaluated the effect of socioeconomic status on vision-related quality of life among open-angle glaucoma patients (n = 186). The results showed patients with a college degree or above had a better quality of life than patients with lower educational attainment [17].

A Delphi study recruiting eye experts from 118 countries (n = 470) including the South Asia region, ranked 16 grand challenges in global eye health from highest priority to least. These 16 challenges were categorized into four sections. The challenges reported from highest to lowest priority were (i) detection and treatment of conditions, (ii) health services and policy, (iii) access and equality, and (iv) human resource capacity [18]. In the Asia-Pacific region, the most common eyecare challenges have been found to be a large and rapidly aging population, a wide spectrum of eye diseases, and imbalanced distribution of resources [19].

In a study conducted in Kabul, Afghanistan among adults aged 50 years and above (n = 3751), it was found that severe vision impairment had a prevalence of 2.2%, while moderate and mild vision impairments had a prevalence of 6.9% and 8.7% respectively. Cataracts were identified as the leading cause of blindness, severe vision impairment, and moderate vision impairment. Additionally, uncorrected refractive error emerged as the primary contributor to mild vision impairment. [20]. Another study conducted in the Nangarhar province of Afghanistan (n = 1281) reported that the most common causes of blindness and vision impairment were cataracts, uncorrected refractive error, glaucoma, age-related macular degeneration, and diabetic retinopathy [21]. The findings of a cross-sectional study in Herat (Afghanistan) (n = 509) indicated that younger adults had low awareness of common eye diseases. However, participants over the age of 35 years reported higher odds of awareness regarding eye diseases [22]. Overall, the World Health Organization estimates that there are 400,000 blind and 1.5 million visually impaired individuals in Afghanistan [23].

Despite the available studies, there is still a paucity of data regarding the impact of eye diseases on the quality of life of individuals in Afghanistan. Therefore, the objective of the present study was to assess the impact of eye diseases on both the physical and mental quality of life among individuals in Herat, Afghanistan.

Design

A cross-sectional study was conducted in Herat province of Afghanistan between January 10, 2022 and April 15 2022. Data from 617 participants were collected from patients visiting an ophthalmologist. The data were collected by means of print-based self-reported surveys (with the questions asked by an interviewer rather than self-completion due to the high rate of illiteracy). The study utilized convenience sampling from patients visiting a private and a governmental eye clinic who agreed to participate in the study.

Measures

The survey used in the present study comprised two sections (socio-economic questions, and quality of life questions). The first section contained questions regarding age, gender (male, female), marital status (single, married, widow/divorced), residency (urban, rural), educational level (illiterate, primary school, secondary school, high school, university), monthly income (less than $50, $50-$100, $100-$200, $200-$300, more than $300), occupational status (employed, unemployed), social media user (yes/no), wore glasses (yes/no), and traumatic event occurring during the past month (yes/no)

The 12-item Short-Form Survey (SF-12v2) was used to assess the quality of life of participants. Although the SF-12 actually assesses the impact of health on an individual's everyday life, according to the SF-12v2 manual and other studies [31], the instrument can be used to assess quality of life. The scale comprises two general components (physical component score [PCS] and the mental component score [MCS]), and eight subcomponents (physical functioning [PF], role-physical [RP], bodily pain [BP], general health [GH], energy/fatigue [VT], social functioning [SF], role-emotional [RE)], and mental health [MH]). Items in the scale (e.g., “During the past week, how much of the time has your physical health or emotional problems interfered with your social activities [like visiting with friends, relatives, etc.]?”) are rated from 1 to 6 with scores ranging from 6 to 20 for physical component score and 6 to 28 for mental component score. Higher score indicates better quality of life in that component. In the present study, the Cronbach’s alpha was 0.88.

Data analysis

IBM SPSS version 26 was used for data entry and data analysis. The frequency option was used to obtain the frequencies and percentage of the socio-economic variables. To evaluate the relationship between categorical variables, chi-square tests were used. A p-value of equal or less than 0.05 was considered significant in the present study. Multinomial logistic regression analysis was used to examine independent socio-demographics with quality of life.

Ethics

Ethical approval for the present study was obtained from the Afghanistan Center for Epidemiological Studies - Ethical Committee (ref: #21.020). During the initial contact with the participants, a description of the study was presented to them. Informed consent was obtained from all the participants in the present study. Participants were aware that they could withdraw at any point in time from the study. All methods were carried out in accordance with relevant ethical guidelines and regulations.

A total of 617 eye patients participated in the present study with an age range of 18 to 100 years. The mean age of the participants was 44.42 years. More than two-thirds of the participants were female (68.1%). Almost three-quarters of the participants were married (72.0%). More than half of the participants were living in urban areas (58.8%) [Table 1].

The quality of life of almost two-thirds of the participants was poor on the physical component score (63.4%). One-seventh of the participants had poor quality of life on the mental component score (14.9%). The physical functioning component of quality of life among almost two-thirds of the participants was poor (60.1%) [Table 2].

The mental component score (MCS) of quality of life among one-fifth of the participants aged above 54 years old was poor (20.4%). MCS of quality of life was poor among almost one-third of the participants who were widow/divorced (28.9%). The mental component of quality of life among one-quarter of the participants with a monthly income of less than $50 was poor (25.0%) [Table 4 ].

Multiple logistic regression was performed to identify predictors of the physical component score of quality of life comprising the following variables: age group, gender, job marital status, residency, education level, occupational status, using social media, wearing glasses, and traumatic event occurring during the past month. The analysis indicated that poor physical quality of life among participants was significantly associated with being above 54 years old (adjusted odds ratio [AOR] = 5.73, p = .0048), being female (AOR = 3.58. p < 0.01), being illiterate (AOR = 3.31, p = 0.01), being unemployed (AOR = 1.93, p = 0.04), and experiencing a traumatic event during the past month (AOR = 2.06, p = 0.02) [Table 5].

Multiple logistic regression was also performed to identify predictors of mental component score of quality of life comprising the following variables: age group, gender, job marital status, residency, education level, occupational status, social media user, wearing glasses, and traumatic event occurring during the past month. The analysis indicated that poor mental quality of life among participants was associated occupational status (being unemployed) (AOR = 3.62, p = 0.05), and experiencing a traumatic event in the past month (AOR = 3.49, p < 0.01).

According to the findings of the present study, sociodemographic factors such as age group, gender, marital status, education level, monthly income, occupational status, being a social media user, and a traumatic event occurring in the past month were all significantly associated with both physical and mental components of quality of life among patients with eye disease, while residency was only associated with the physical component of the quality of life.

More specifically, there was a significant association between age and both physical and mental components of quality of life among patients with eye diseases (i.e., being aged above 54 years). This concurs with research conducted in Northwest Ethiopia which found that individuals older than 75 years of age reported a lower quality of life compared to younger participants [9].

Additionally, the present study’s findings find corroborate with previous studies in Afghanistan. For instance, a study carried out in the Nangarhar province found that as age increased, instances of visual impairment and blindness tended to increase, despite the absence of a significant increase in low vision cases [21]. This age-associated trend is particularly evident among older adults. Age-related issues such as decreased mobility and challenges in managing daily tasks can significantly impact individual’s quality of life [24]. For individuals experiencing visual impairment due to eye diseases, these age-associated challenges can be exacerbated, leading to further declines in quality of life.

To further explore these relationships and to identify predictors of mental and physical component scores of quality of life, logistic regression analyses were carried out. Despite the noticeable age-related trends, no statistically significant association was found between the participants' age and their mental quality of life. However, individuals over 54 years of age were significantly more likely to report worse physical quality of life. One possible explanation for this disparity between physical and mental quality of life could be the differential resilience of mental and physical health to aging and illness. Whereas physical health might deteriorate more rapidly with age and disease progression, mental health may be bolstered by factors such as adaptive coping strategies, social support, and life experience. Further research is needed to clarify the reasons for these differences and to develop effective strategies that consider the varying needs of different age groups within this patient population.

Another finding was the significant relationship between monthly income and the quality of life among patients with eye diseases. Descriptive data suggested that higher income was generally associated with a higher quality of both physical and mental life. It is important to note that replication studies are needed to confirm the significance of this observed pattern. This finding concurs with the results from a study conducted in Nangarhar, Afghanistan, which reported an association between self-reported poor economic status and vision impairment [21]. A reasonable explanation for this could be the financial problems encountered when managing eye diseases. A lower income may curtail access to necessary healthcare services, medications, and other therapeutic resources, possibly leading to less efficient management of eye diseases and, subsequently, a decline in quality of life. Conversely, those with a higher income may have access to better healthcare resources enabling them to manage their health conditions more effectively, therefore maintaining a relatively higher quality of life. Further research is needed to examine whether this finding occurs across countries that have free access to healthcare (e.g., UK). However, it should be noted that that income was not a significant predictor in the regression model.

The present study also found several other factors significantly associated with the mental and physical quality of life among patients with eye diseases. Being female, being divorced/widowed, being illiterate, being unemployed, not using social media, and having experienced a traumatic event within the past month were found to be associated with both physical and mental quality of life. However, residency (i.e., living in a rural area) was only associated solely with poor physical quality of life, suggesting living conditions impact more negatively on physical well-being than mental wellbeing.

Multiple logistic regression analysis was carried out to further examine these associations. Unemployment and experiencing a traumatic event in the past month both emerged as significant predictors for lower mental and physical quality of life among participants. Being female was a significant predictor of poor physical (but not mental) quality of life.

It's notable that other studies have similarly associated gender, occupational status, and recent traumatic experiences to quality of life. For instance, a cross-sectional web-based registry study reported gender differences in quality of life among individuals with eye diseases, with females often reporting lower quality of life scores than males [25]. This disparity might be driven by a combination of biological differences, gender-specific health concerns, and social factors such as gender roles and expectations. In contrast, the results of a study on quality of life among patients with a very specific form of eye disease (i.e., anterior uveitis) reported no significant association between gender and quality of life [26]. Further exploration of different eye diseases is required to reconcile these differing outcomes.

The findings of the present study showed participants who were using social media reported better quality of life than those who were not using it. Although some studies have highlighted that using social media is associated with poor quality of life, such studies refer to problematic social media use [27]. Indeed, studies examining non-problematic social media use have shown that using social media can have a positive impact on quality of life among its users [28, 29]. The positive impact of social media on individuals' quality of life can be attributed to a variety of factors. This can be due to the benefits of social media uses such as connection and social support, which foster a sense of belonging and provide emotional sustenance. Additionally, social media platforms offer opportunities for networking, enabling individuals to forge professional relationships and explore career possibilities. Furthermore, social media serves as a medium for creativity and self-expression, allowing users to showcase their talents and receive feedback from a global audience. Lastly, social media platforms can be a source of inspiration and motivation, exposing individuals to diverse ideas and success stories. Collectively, these benefits contribute to an enhanced quality of life for many social media users [28, 29].

The present study also found that illiterate participants were more likely to report having a have poor quality of life. This concurs with other studies which have also reported a similar relationship [30, 32, 33]. Being illiterate often means that opportunities in life (e.g., career advancement) are limited, which is associated with poorer income. These consequences are associated with poorer life quality. Regarding occupational status, the World Health Organization (WHO) recognizes unemployment and job insecurity as social determinants of health [34]. Studies have shown that unemployed individuals often exhibit a poorer quality of life than their employed counterparts [35]. The low quality of life of unemployed individuals might be related to factors such as a lack of perceived meaningfulness in life for some, and financial dissatisfaction [36].

Although there are no previous studies examining the association between traumatic experiences and quality of life among patients with eye diseases in Afghanistan, the present study’s findings align with prior research that explores the impact of trauma on quality of life. Extant research suggests that trauma can directly reduce quality of life or indirectly influence it through the mediation of mental distress [37]. Additionally, there is evidence to suggest that post-traumatic stress disorder (PTSD) symptoms are associated with a poor quality of life [38]. However, it is important to note that these studies are not specific to eye disease patients and may not fully capture the unique circumstances and challenges faced by this particular population. Therefore, the present study contributes to the understanding of this relationship in the context of patients with eye diseases in Afghanistan and highlights the need for further research to better address their specific needs and experiences.

The results of the present study highlight a potentially complex interplay of sociodemographic factors impacting the quality of life among patients with eye diseases. The findings contribute to this growing body of knowledge, offering further insight into the determinants of quality of life in this patient population. However, more comprehensive studies are needed to delineate these relationships and discern the underlying mechanisms.

There are some limitations that need to be taken into account when interpreting the present study’s findings. First, the study comprised self-report data which can lead to biased responses. Second, the study design was cross-sectional which limits the long-term assessment of specific factors such as experience of a traumatic life event, as well as being unable to determine the causality between the study variables. Third, the study was only carried out in one area of Afghanistan so the findings may not generalize to other areas of Afghanistan (or other countries). Fourth, the sample had a gender imbalance (with two-thirds being female) which also biases the findings and affects generalizability.

Further studies are needed to understand how sociodemographic factors are associated with the quality of life of patients with specific eye diseases. The present study provides a novel contribution to the field of eye diseases and quality of life especially in relation to Afghanistan where there has been very little previous research in this area. No previous study has used the approach of identifying both mental and physical components of quality of life among Afghan patients with eye diseases. The results of the present study indicate that public health authorities in Afghanistan should implement policies to raise awareness regarding the quality of life of patients with eye diseases as well as formulating strategies to help improve it.
