“…Similar studies reported refractive error as the third [6,19], second [4] and commonest [11,17,20] cause of ocular morbidity. In a study by Kumah et al [13] in Ghana, the most prevalent condition was refractive error (26.30%).…”

“…Similarly, Adeoye and Omotoye [4] reported figures of 26% for cataract and 10.9% for glaucoma in a study in south west Nigeria. Amadi et al [12] however reported less than 5% for both disease conditions. This difference may due to the fact that their study had a mean age of 30.5 years while the mean age for this study was 45.99 years.…”

“…Conjunctivitis was the commonest ocular morbidity in a similar study by Adenuga and Samuel [4] with a prevalence of 42%. Other studies reported it as the third leading cause of ocular morbidity with prevalence of less than 20% [4,[10][11][12]. Kumah et al [13] in their study reported it as the condition with the second highest prevalence.…”

Purpose: The aim of the study was to determine the pattern of ocular conditions among patients who attended the Salvation Army Eye Clinic at Wiamoase in the Ashanti Region of Ghana in 2016.Method: A retrospective study of all patients attending the Salvation Army eye clinic at Wiamoase in 2016 was done.Results: A total of 1000 folders were used in the study. There were 382 males (38.20%) and 618 females (61.80%) with a male to female ratio of 1:1.6. The mean age was 45.99 years (SD= ± 27.69). The commonest eye disorder encountered was conjunctivitis (39.70%). This was followed by cataract (24.40%), glaucoma (9.70%) and refractive errors (8.90%). 96.72% of cases of cataract and 85.57% of cases of glaucoma occurred in those above 40 years. Of those with refractive error, there were 40.45% with myopia, 34.83% with astigmatism and 24.72% with hyperopia. Conjunctivitis and cataract were significantly higher in females with p values of 0.008 and 0.000 respectively using the chi square test. However, there was no significant difference in the prevalence of glaucoma and refractive errors between males and females with p values of 0.189 and 0.255 respectively. Presbyopia was significantly higher in males with p values of 0.017. Conclusion:Conjunctivitis, cataract, glaucoma and refractive errors were the major ocular conditions seen in this study. Efforts aimed at reducing ocular morbidity should target these conditions.

Purpose: To determine vision-specific and psychosocial implications of low vision among patients with low vision visiting the Low Vision Centre of the Eastern Regional Hospital in Ghana.Methodology: This was a descriptive case-control study of 41 patients with low vision and 41 patients with normal vision recruited from the Low Vision Centre of the Eastern Regional Hospital by simple random sampling. Data on vision-specific and psychosocial impacts of low vision was collected using the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25). Biographical and clinical characteristics such as age, gender, educational status, marital status, employment and income status were gathered from consenting patients. Mann–Whitney U analysis using Statistical Package for Social Scientists (SPSS) was conducted to compare scores on vision-specific and psychosocial subscales of the NEI VFQ-25 between patients with low vision and patients with normal vision.Results: Patients with low vision recorded the lowest score on the driving subscale (median = 8.33, IQR [interquartile range]: 8.33–41.67, n = 41, p < 0.001), as well as on distance activities (median = 35.42, IQR = 16.70–58.80). Psychosocial implications of low vision included high dependency (median = 33.33, IQR = 25.00–50.00), reduced mental health (median = 37.50, IQR = 25.00–50.00) and limitation in partaking in social activities (median = 50.00, IQR = 37.50–78.00).Conclusion: Low vision has both vision-specific and psychosocial implications for the patients. Low vision management and services should therefore be tailored to meet these psychosocial and vision-specific needs to enable patients better accept their visual changes and to be better prepared to use their remaining vision to achieve their daily goals.

“…While Africa hosts 11.9% of the World population, it also disproportionately accounts for about 15% of those avoidably blind. Sub-Saharan Africa carries the worse burden with 4.8 million blind partly due to 66% population growth [5]. Other factors accounting for this include scarcity of eye care personnel, limitation in technology and training for eye care, lack of local production of eye medicine, and other consumables leading to dependency on importation in the presence of limited foreign exchange availability, unrestrained and unregulated malpractices of quacks, and traditional eye care providers.…”

Difficulties in Cataract Surgery

Background: Sub-Saharan Africa disproportionately accounts for high number of avoidably blind largely caused by cataracts.The blindness burden: Limitation in human and material resource for delivery of cataract surgical services, cost, gender, distance to hospital, time off for the care giver, fear of surgery, uncultured behavior of eye care personal, poor visual outcome, general governments neglect of health care, lack of health insurance for vast majority of the population, healthcare funded by individuals as out of pocket despite grinding poverty, reliance on poorly coordinated and unsustainable outreach program, malpractices of quacks and traditional eye healers amongst other reasons.More than just a cataract: Cataract services require systematic evaluation of the patients' general condition as well as the eye. Appropriate counseling is required to understand the goal and expectation of treatment. Adequate planning of surgery includes ocular biometry and provision of the appropriate intra ocular lens. The management protocol must ensure adequate measures are taken to prevent/ manage critical incidents whenever such a need arises. Conclusion:Cataract surgical services need to be patient centered with the goal of optimizing resources for quality outcome without compromising safety.

Prevalence and causes of vision loss in sub-Saharan Africa: 1990–2010

Abstract: The age-standardised prevalence of blindness and MSVI decreased substantially from 1990 to 2010, although there was a moderate increase in the absolute numbers with blindness or MSVI. Significant subregional and gender disparities exist.
