Impact of Visual Impairment and Blindness on Quality of Life of Patients in Owerri, Imo State, Nigeria

Quality of life and associated factors among patients with glaucoma attending at Boru Meda General Hospital, Northeast Ethiopia

Glaucoma significantly impacts the well-being of millions of people worldwide and contributes to a decline in quality of life. Therefore, this study aimed to evaluate quality of life and identify influencing factors among glaucoma patients receiving care at Boru Meda General Hospital in Northeast Ethiopia in 2022. A hospital-based cross-sectional study was conducted at Boru Meda General Hospital from July 10 to September 10, 2022. A total of 432 glaucoma patients were selected through a simple random sampling technique. The participants were interviewed via a structured questionnaire, including the modified Glaucoma Quality of Life-15 tool. The data collected were processed by cleaning, coding, and entering into EPi-data version 4.6 and then analysed via SPSS version 26. Variables with a p value less than 0.05 at the 95% confidence interval were considered statistically significant. A total of 417 participants participated in the study, resulting in a response rate of 96.4%. Among them, 187 individuals, accounting for 44.2% (95% CI 39.8-49.9%), reported having poor quality of life. Factors such as being diagnosed for more than 6 years, residing in rural areas, having other ocular diseases, having bilateral glaucoma, receiving treatment for 1-5 years, experiencing moderate anxiety, and facing moderate depression were significantly associated with poor quality of life, with adjusted odds ratios ranging from 2.555 to 8.035. Approximately half of the participants experienced a diminished quality of life, and significant associations were found with rural residence, time since diagnosis, treatment duration, the presence of other ocular conditions, bilateral glaucoma, and levels of anxiety and depression. The implementation of community-based glaucoma screening initiatives aimed at early identification and treatment, particularly those focused on rural communities and individuals with bilateral glaucoma, is crucial.

Analysis of quality of life of patients with refractive errors in India

INTRODUCTION

It is important to determine the health-related quality of life (HRQoL) to devise population-based cost-effective service delivery models. The present study aimed to evaluate the HRQoL of patients with refractive errors (RE) using generic and vision-specific instruments, identify the determinants of HRQoL, and examine the validity between the quality-of-life instruments for refractive errors.

METHODS

Face-to-face interviews were conducted with 515 participants with RE using generic as well as vision-specific HRQoL measures. Mean EuroQol-five dimensions-five levels (EQ-5D-5L) utility value, National Eye Institute-Visual Function Questionnaire-25 (NEI-VFQ-25) composite score, and EuroQol-Visual analogue scale (EQ-VAS) score were computed, and determinants of quality of life were determined using generalized linear regression model. The validity between generic and disease-specific measures was ascertained using Pearson's coefficient.

RESULTS

The mean EQ-5D-5L utility score for patients with RE was estimated as 0.72 (95% CI: 0.70-0.75). The mean NEI-VFQ-25 composite score and EQ-VAS score were 71.3 (95% CI: 69.8-73), and 74.7 (95% CI: 73.4-76.1), respectively. Visual acuity, gender, and presence of co-morbidities were significantly associated with quality of life. The concurrence between the generic and vision-specific instruments was found to be low to moderate.

CONCLUSION

The findings of the study indicate the importance of the value of quality of life for patients with RE, which could be taken into account by health administrators, doctors and researchers to carry out economic evaluations, since these measures provide a basis for an evaluation more precisely the impact of RE and guide the determination of efficient ways to alleviate the burden of treatable visual impairment. More research is required to explore the potential integration of a vision component, the sixth dimension, into the EQ-5D-5L instrument, given the moderate agreement observed between the generic and specific assessment tools.

Utilisation of eye health services and compliance with spectacles wear among community school adolescents: a mixed-methods study from Bagmati province of Nepal

OBJECTIVES

This study aims to determine the factors influencing eye care service utilisation and compliance with spectacles wear among school students.

DESIGN

Mixed-methods study.

SETTING

27 community schools from 6 districts of Bagmati province of Nepal.

PARTICIPANTS

Adolescents with mild vision impairment who were screened at schools by their trained peers for visual acuity measurement and subsequently received subsidised spectacles for refractive error correction. For the quantitative study, 317 students from 21 schools completed the survey. For qualitative study, 62 students from 6 schools participated in 6 focus group discussions.

PRIMARY OUTCOME MEASURES

Utilisation of eye care services and compliance with spectacles wear.

RESULTS

Among 317 students, 53.31% were aged 15-19, and 35.96% were male. More than half (52.68%, n=167) did not use eye health services. Among students who did not go, 51.50% reported eye health facilities being far away. Thematic analysis showed that distance, COVID-19 and awareness were influential in the utilisation of eye care. The multivariate analysis showed urban residents were likelier (adjusted OR (AOR) 4.347, 95% CI 2.399 to 7.877, p<0.001) to use eye care services. During an unannounced visit to schools after 3-4 months of spectacles distribution, 188 (59.31%) students were wearing spectacles. 20.16% of students not wearing spectacles reported they did not feel the need. Thematic analysis showed the influence of family and peers, affordability, aesthetic appearance, comfortability and symptomatic relief in spectacles compliance. The multivariate analysis showed that urban residents (AOR 2.552, 95% CI 1.469 to 4.433, p<0.001), older adolescents (AOR 1.758, 95% CI 1.086 to 2.848, p=0.022), mothers with paid jobs (AOR 2.440, 95% CI 1.162 to 5.125, p=0.018) and students visiting eye care centres (AOR 1.662, 95% CI 1.006 to 2.746, p=0.047) were more likely to be compliant with spectacles wear.

CONCLUSIONS

There are multiple barriers for students to use eye care services and stay compliant with spectacles wear. Eye health programmes should include eye health promotion and be accessible, affordable and equitable.

Clinical Patterns and Factors Contributing to Ophthalmic and Otologic Events Associated With Immune Checkpoint Inhibitors: A Narrative Review

Immune checkpoint inhibitors, which are a type of cancer immunotherapy, have been associated with the development of adverse events related to an overactive immune system caused by the effect of this type of therapy. It affects a wide range of organs, including the ear and eye. Ophthalmic toxicity related to immune checkpoint inhibitors usually occurs bilaterally. Corneal toxicity (mainly dry eye disease) and uveitis are the most commonly reported patterns of toxicity. Other patterns of involvement include optic neuritis, serous retinal detachment, keratitis, ophthalmoplegia, and ocular myasthenia, but are not limited to them. Potential factors contributing to the development of toxicity are age, previous history of ocular immune disease, type, doses, and duration of treatment, and race. Ototoxicity is also reported in the literature, usually manifesting as bilateral, symmetrical/asymmetrical hearing loss. Ear toxicity presenting as ear fullness, tinnitus, and vertigo has also been mentioned in the literature. Hearing loss is often associated with word/speech recognition. An audiogram usually shows a pattern of sensorineural hearing loss. Otitis media has also been reported to be a potential cause of ear toxicity. Immune checkpoint inhibitor toxicity was present more commonly when used along with other anti-neoplastic agents. Ear toxicity, which presumably results from damage to the melanocytes in the ear, often presents with other melanocytotic manifestations, like uveitis and vitiligo. According to the literature, some agents (ipilimumab, nivolumab, atezolizumab, and pembrolizumab) were more commonly associated with toxic effects on the eye and ear and more when combined with each other.

Management of painful blind eye in Africa: A review

Background

Painful blind eye conditions in Africa constitute a compelling area of concern within public health, presenting substantial complexities for healthcare systems and the individuals afflicted. This comprehensive review delves into recent research and advancements concerning the management of these conditions across the African region. Drawing upon contemporary studies and data, we scrutinise the multifaceted aspects, including prevalence rates, causative factors, and regional variations.

Objective

To review existing articles on the current state of the management of blind painful eye conditions in Africa.

Materials and Methods

Articles regarding the subject were obtained from Google Scholar, AJOL, and PubMed using the keywords, painful, blind eye (PBE), Africa.

Results

Forty-four relevant articles were reviewed. They were further categorized into epidemiology, management approaches and challenges to management.

Conclusion

The management of the PBE poses a huge challenge and can either be medical or surgical. Collaborative efforts should be targeted at preventing the causes of a PBE. As the burden of painful blind eye conditions continues to exert a profound impact across Africa, this article underscores the pressing need for collaborative efforts involving governments, non-governmental organisations, and international entities. By prioritising awareness and enhancing healthcare accessibility, we collectively strive towards the alleviation of suffering and the prevention of avoidable visual impairment in this region.

Prevalence and Risk Factors of Blindness Among Primary Angle Closure Glaucoma Patients in the United States: An IRIS Registry Analysis

PURPOSE

To assess the prevalence and risk factors of blindness among patients newly diagnosed with primary angle closure glaucoma (PACG) in the United States.

DESIGN

Retrospective cross-sectional study.

METHODS

Eligible patients from the American Academy of Ophthalmology (AAO) Intelligent Research in Sight (IRIS) Registry had newly diagnosed PACG, defined as: 1) observable during a 24-month lookback period from index date of PACG diagnosis; 2) no history of eye drops, laser, or cataract surgery unless preceded by a diagnosis of anatomical narrow angle (ANA); and 3) no history of glaucoma surgery. Logistic regression models were developed to identify risk factors for any (one or both eyes) or bilateral (both eyes) blindness (visual acuity ≤20/200) at first diagnosis of PACG.

RESULTS

Among 43,901 eligible patients, overall prevalence of any and bilateral blindness were 11.5% and 1.8%, respectively. Black and Hispanic patients were at higher risk of any (odds ratios [ORs] 1.42 and 1.21, respectively; P < .001) and bilateral (ORs 2.04 and 1.53, respectively; P < .001) blindness compared with non-Hispanic White patients adjusted for ocular comorbidities. Age <50 or >80 years, male sex, Medicaid or Medicare insurance product, and Southern or Western practice region also conferred a higher risk of blindness (OR > 1.28; P ≤ .01).

CONCLUSIONS

Blindness affects 1 of 9 patients with newly diagnosed PACG in the IRIS Registry. Black and Hispanic patients and Medicaid and Medicare recipients are at significantly higher risk. These findings highlight the severe ocular morbidity among patients with PACG and the need for improved disease awareness and detection methods.

Comparative Analysis of Health- and Vision-Related Quality of Life Measures among Trinidadians with Low Vision and Normal Vision-A Cross-Sectional Matched Sample Study

This cross-sectional study investigated the health-related and vision-related quality of life measures of adults with low vision compared to healthy individuals in Trinidad and Tobago. The health-related quality of life (HRQOL-14) and the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ-25) were administered to 20 participants with low vision caused by diabetic retinopathy, retinitis pigmentosa, glaucoma, and macular degeneration, as well as 20 participants with no visual problems (control). Participants were recruited from the University Eye Clinic in Trinidad and Tobago. Compared to the controls, more participants in the low-vision group had lower age-adjusted NEI-VFQ-25 scores (48.3% vs. 95.1%; p < 0.001), had poor general (47.5% vs. 10%, p = 0.004) and mental (100% vs. 10%, p < 0.042) health, experienced greater activity limitation due to impairment or health problems (85% vs. 20%, p < 0.001), needed help with personal care (27.5% vs. 0%, p < 0.009) and daily routine (67.5% vs. 0%, p < 0.001), and experienced sleep problems (97.5% vs. 65%, p < 0.001) and symptoms of anxiety (100% vs. 90%, p = 0.042). All the diabetic retinopathy participants (100%, p = 0.028) had two or more impairments or vision problems compared to none in the other low-vision participants. In summary, the HRQOL-14 and NEI-VFQ-25 scores were significantly reduced in low-vision participants, who also demonstrated a greater vulnerability to poor quality of life in the presence of diabetes retinopathy. These findings have important clinical implications regarding offering appropriate support and interventions to improve quality of life outcomes in individuals with low vision.

In vitro nematocidal potential of hydro-ethanolic and aqueous extracts of Calotropis procera (Aiton) W.T. Aiton, 1811 (Apocynaceae) and Faidherbia albida (Delile) A. Chev., 1934 (Fabacae) against Onchocerca ochengi and Caenorhabditiselegans

Onchocerciasis caused by Onchocerca volvulus Leuckart, 1893 is the second-world infection responsible for human blindness. Except Ivermectin which has as targets the microfilariae of that parasite, specific treatment for this disease does not exist and in developing countries, medicinal plants seem to remedy that health problem. For that, aqueous and hydro-ethanolic leaf, bark, and root extracts of Calotropis procera and Faidherbia albida were evaluated in vitro, against the most popular bovine model, Onchocerca ochengi and the free-resistant nematode Caenorhabditis elegans. O. ochengi microfilariae and adults extracted from the bovine nodules and skins as well as the free strains of C. elegans were exposed to the various concentrations of the plant parts extracts and Ivermectin. In results, all the plant parts extracts were rich in tannins, saponins, alkaloids, flavonoids, phenols, coumarins, and glycosides. Phenols (175.45 ± 0.01 mg EGA/g DM), flavonoids (158.98 ± 0.05 mg EC/g DM), and tannins (89.98 ± 2.56 mg ETA/g DM) contents were high in the bark hydro-ethanolic extract of F. albida. The leaf hydro-ethanolic extract of F. albida induced high activity against O. ochengi microfilariae (CL₅₀ = 0.13 mg/mL). The bark hydro-ethanolic extract of F. albida was also the most effective on O. ochengi adults and particularly on female adults (CL₅₀ = 0.18 mg/mL). Against the parasite strain resistant to Ivermectin, F. albida leaf hydro-ethanolic extract appeared more active with CL₅₀ = 0.13 mg/mL. Similarly, the bark hydro-ethanolic extract of F. albida was the most potent on the wild strain of C. elegans. Thus, this study validates the use of these plants by traditional healers in the management of onchocerciasis and suggests a new source of isolation of the potential plant compounds against Onchocerca.

Visual Impairment and Blindness among Patients at Nigeria Army Eye Centre, Bonny Cantonment Lagos, Nigeria

Background: Visual impairment (VI) is a public health problem that can affect an individual’s social wellbeing. The study aims to determine the distribution and causes of vision impairment (VI) and blindness among patients at Nigerian Army Eye Centre Lagos, Nigeria. Method: An institutional cross-sectional study was conducted, and a systematic random sampling technique was used to enrol study participants from their medical records. Information about their demography, presenting visual acuity (VA), best corrected visual acuity and cause of VI and blindness, were retrieved. Result: A total of five hundred (500) medical records of patients aged from 4 to 96 years, with a mean age of 54.07 ± 21.43 years, were considered for the study. Among the participants, more than half were males (51.2%) and ≥60 years (53.0%). A large (47.2%) proportion of the patients had moderate VI at the time of presentation, followed by blindness (22.0%). The major cause of blindness was cataract, while glaucoma and refractive error were the major causes of VI. Blindness and VI were significantly associated with the type of VI before and after the provision of intervention (p < 0.05) across different age groups (children, youths, adults, elderly) with an adjusted p < 0.003 after an intervention. Conclusions: Cataracts, glaucoma and uncorrected refractive error (URE) were the major causes of VI and blindness in Lagos State. VI was more prevalent in males than females; however, there was no significant difference between the two proportions. The prevalence of VI among age groups was more significant for those 60 years and above. Early screening for the detection and management of cataract, URE and glaucoma is highly advised to reduce the burden of VI.

Vision-related quality of life amongst patients with low vision and blindness in a resource-limited country

PURPOSE

To evaluate the significance of sociodemographic and clinical variables on the quality of life of low-vision patients in a tertiary hospital in Enugu, Nigeria, and also determine the causative ocular pathologies and their vision-related quality of life.

METHODS

A cross-sectional study of adults 18 years and above with low vision/blindness. They were consecutively enrolled and clinically evaluated. The WHO-NEI-VFQ-25 questionnaire for quality of life was administered. Descriptive statistics were used to summarize variables. Kruskal-Wallis test, analysis of variance, and post hoc tests were done where appropriate.

RESULTS

Of the 400 participants, 81% were above 40 years. Mean age was 57.27 ± 16.34 years. Males (52.0%) and females (48.0%). 225 (56.25%) had Moderately Severe Visual Impairment. Low vision/blindness negatively affected the different domains of quality of life significantly, except ocular pain and dependency. Glaucoma and Cataract were the major disease conditions that affected most of the domains significantly. These conditions when poorly managed, due to poor and limited health resources, progress to low vision/blindness. Of all the socio-demographic factors and clinical variables studied, only age and severity of low vision were significant predictors of quality of life.

CONCLUSION

There is the need for prompt and proper treatment of low-vision patients and advocacy for the establishment of adequate and functional rehabilitation services. Quality of life which measures the overall impact of a disease on an individual was low in people with low vision and blindness. Low-vision services, which include rehabilitation, will provide comprehensive eye-care services and thus improve their quality of life.

Visual impairment as a predictor for deterioration in functioning: the Leiden 85-plus Study

BACKGROUND

Visual impairment frequently occurs amongst older people. Therefore, the aim of this study was to investigate the predictive value of visual impairment on functioning, quality of life and mortality in people aged 85 years.

METHODS

From the Leiden 85-plus Study, 548 people aged 85 years were eligible for this study. Visual acuity was measured at baseline by Early Treatment Diabetic Retinopathy Study charts (ETDRS). According to the visual acuity (VA) three groups were made, defined as no (VA > 0.7), moderate (0.5 ≤ VA ≤ 0.7) or severe visual impairment (VA < 0.5). Quality of life, physical, cognitive, psychological and social functioning were measured annually for 5 years. For mortality, participants were followed until the age of 95.

RESULTS

At baseline, participants with visual impairment scored lower on physical, cognitive, psychological and social functioning and quality of life (p < 0.001). Compared to participants with no visual impairment, participants with moderate and severe visual impairment had an accelerated deterioration in basic activities of daily living (respectively 0.27-point (p = 0.017) and 0.35 point (p = 0.018)). In addition, compared to participants with no visual impairment, the mortality risk was 1.83 (95% CI 1.43, 2.35) for participants with severe visual impairment.

DISCUSSION

In very older adults, visual impairment predicts accelerated deterioration in physical functioning. In addition, severely visually impaired adults had an increased mortality risk. A pro-active attitude, focussing on preventing and treating visual impairment could possibly contribute to the improvement of physical independence, wellbeing and successful aging in very old age.

Vision impairment and self-reported anxiety and depression in older adults in Nigeria: evidence from a cross-sectional survey in Kogi State

BACKGROUND

More than 2 billion people are thought to be living with some form of vision impairment worldwide. Yet relatively little is known about the wider impacts of vision loss on individual health and well-being, particularly in low- and middle-income countries (LMICs). This study estimated the associations between all-cause vision impairment and self-reported symptoms of anxiety and depression among older adults in Kogi State, Nigeria.

METHODS

Individual eyes were examined according to the standard Rapid Assessment of Avoidable Blindness methodology, and anxiety and depression were assessed using the Washington Group Short Set on Functioning-Enhanced. The associations were estimated using multivariable logistic regression models, adding two- and three-way interaction terms to test whether these differed for gender subgroups and with age.

RESULTS

Overall, symptoms of either anxiety or depression, or both, were worse among people with severe visual impairment or blindness compared with those with no impairment (OR=2.72, 95% CI 1.86 to 3.99). Higher levels of anxiety and/or depression were observed among men with severe visual impairment and blindness compared with women, and this gender gap appeared to widen as people got older.

CONCLUSIONS

These findings suggest a substantial mental health burden among people with vision impairment in LMICs, particularly older men, underscoring the importance of targeted policies and programmes addressing the preventable causes of vision impairment and blindness.

Quality of life of older adults and associated factors in Ghanaian urban slums: a cross-sectional study

OBJECTIVE

This study provides insight into the quality of life (QoL) of older adults living in urban slums in Ghana.

DESIGN

The study employed a community-based, cross-sectional design to assess QoL among older adults in two slums between April and May 2020. QoL was assessed using the WHO Quality of Life-Brief version (WHOQOL-BREF) questionnaire.

SETTINGS

Participants were drawn from two slums in Ghana, one in a fishing-dominated community and the other in an industrial community.

PARTICIPANTS

This study included 400 participants aged 60 and above who had lived in either slum for at least 1 month and were able to communicate verbally.

RESULTS

Although the means of all participants' transformed scores were poor in the physical and psychological domains, they were moderate in all other domains. When viewed as a whole, the perceived overall QoL is neither poor nor good and participants were neither satisfied nor dissatisfied with their health. Participants had a moderate level of QoL in the WHOQOL-BREF psychological (mean score 45.7), social (mean score 57.0) and environmental (mean score 51.6) domains. The mean score for physical QoL of older adults was 43.3, which denotes poor QoL. In all domains, male participants have a significantly higher mean QoL than their female counterparts. An analysis of variance comparing the living arrangements of participants showed that those who lived with extended family had high mean scores in environmental QoL, overall QoL and satisfaction with health. Regression analysis revealed that QoL was influenced mostly by the environmental (46.2%), followed by the psychological (43.7%), physical (31%) and social (20.4%) domains.

CONCLUSIONS

The findings from this study show that older adults living in slums had moderate psychological, social and environmental QoL and poor physical QoL. Although the mean scores for QoL are higher than anticipated, health policy development must take into account the specific needs of older adults.

[Overview of visual impairment at the Yalgado Ouédraogo University Medical Center: Study of 501 cases]

OBJECTIVE

To determine the main causes of visual impairment according to age in patients admitted to the ophthalmology department.

MATERIALS AND METHODS

This was a retrospective study of 501 cases of visual impairment. Included were patients of both sexes whose best-corrected visual acuity in the better eye was strictly less than 5/10. The parameters studied were age, gender, place of residence, corrected visual acuity in the better eye, and diagnosis. The data were entered and processed with the Epi info 7.2 software.

RESULTS

Subjects over 50 were the most prevalent (48.5%). In patients over 50 years of age, cataracts (54.32%) were the leading cause of visual impairment, followed by glaucoma (24.69%) and non-glaucomatous optic neuropathy (26.19%). Trauma (17.62%) was frequently found in patients aged 16 to 50 years. Tropical endemic limbo-conjunctivitis (25.00%) was the leading cause of visual impairment in subjects aged 5 to 15 years.

CONCLUSION

This study confirms the results of the literature, which have shown that cataracts are the leading cause of visual impairment in developing countries. A major effort to raise awareness, provide information and therapeutic care would reduce the incidence of visual impairment.

Phakic intraocular lens implantation in a case of Tourette syndrome exacerbated by wearing glasses and contact lenses

A 25-year-old longsighted woman presented with a history of spectacle and contact lens induced exacerbation of Tourette syndrome symptoms. Preoperatively, she had very poor unaided vision (6/60), achieving good (6/9) vision in both eyes with spectacle correction. The patient underwent bilateral simultaneous implantation of phakic implantable collamer lens (ICL) implants (STAAR, USA) which sit in front of the natural lens. Postoperatively, her uncorrected visual acuity was markedly improved as were her manifestations of Tourette syndrome. She achieved her full potential of unaided vision (6/9). This is the first documented case of Tourette syndrome triggered by glasses and contact lenses in which bilateral phakic toric lens implants were effective in improving vision and controlling motor symptoms. Phakic toric ICL implantation is a reversible technique for the correction of visually significant ametropia in selected patients and has improved this patient's quality of life.

Axial length of cataract eyes: a comparison of two cohorts over a span of 10 years apart

BACKGROUND

To assess the associations of axial length with age-related cataract within a span of 10 years in an Asian population in southern Taiwan.

METHODS

A retrospective cohort study examined 960 adults who underwent cataract surgery at the Kaohsiung Chang Gung Memorial Hospital in year 2008 and year 2018. Axial length was assessed with the ultrasound biometry and/or the Zeiss IOLMaster. Eyes with prior blunt eye trauma or had underwent vitrectomy operations were excluded. The significance of the changes in axial length between the two cohorts was determined after performing age-matched analyses. Due to utilization of ultrasound biometry and/or Zeiss IOLMaster, axial length corrections with our mean difference in measurement results, which were similar to previous studies on comparison between the two measurement tools, were carried out.

RESULTS

Axial length showed an age-related elongation in 10-year cross-sectional data, from a mean of 23.65 ± 1.80 mm in year 2008 to a mean of 24.30 ± 1.90 in year 2018 (p = 0.003). Patients with high myopia (axial length > 26 mm) increased significantly over the 10-year period from 8.1 to 16 % (p < 0.001). A birth cohort effect on axial length was evident as the axial lengths of year 2008 cohort were shorter than the 2018 cohort when they were in the same operation age group. In particular, persons born after the 1960s demonstrated a predominant increase in axial length in both cohorts.

CONCLUSIONS

Our study confirms a trend in increase of axial myopia, especially high myopias, over the 10-year period. A novel finding of this study was discovering a birth cohort effect on axial length, especially in persons born after the 1960s in southern Taiwan.
