Purpose: The purpose was to estimate the prevalence of blindness due to cataract, assess visual outcomes of cataract surgery, and determine the cataract surgical coverage rate and barriers to uptake of services among individuals aged 50 years or older in Plateau State, Nigeria. Materials and Methods: A population-based, cross-sectional survey of 4200 adults 50 years or older was performed. Multistage stratified random sampling, with probability proportional to size was used to select a representative sample. The Rapid Assessment of Cataract Surgical Services protocol was used. Statistical significance was indicated by (P < 0.05). Results: The cohort comprised 4115 subjects (coverage: 98%). The prevalence of bilateral blindness due to cataract was 2.1%, [95% confidence intervals (CI): 1.7-2.5%] in the entire cohort, 2.4% in females (95% CI: 1.8-3.8%); and 1.8% in males (95% CI: 1.2-2.4%) (X
2 -0.85,P> 0.05). The prevalence of monocular blindness due to cataract was 5.9% (95% CI: 5.2-6.6%). The cataract surgical coverage for subjects with visual acuity (VA) less 3/60 was 53.8% in the entire cohort; 60.5% for males and 48% for females (X2 = 2.49, P > 0.05). The couching coverage for subjects who were blind was 12%. A total of 180 eyes underwent surgical intervention (surgery or couching) for cataract, of which, 48 (26.7%) eyes underwent couching. The prevalence of bilateral (pseudo) aphakia was 1.5%, (95% CI: 1.2-1.9%) and 2.7% (95% CI: 2.2-3.2%) for unilateral (pseudo) aphakia. Visual outcomes of the 180 eyes that underwent surgical intervention were good (VA ⩾ 6/18) in 46 (25.6%) eyes and poor (VA < 6/60) in 105 (58.3%) eyes. Uncorrected aphakia was the most common cause of poor outcome (65.1%). Most subjects who underwent cataract surgery were not using spectacles 74 (71.2%). Cost and lack of awareness were the main barriers to uptake of cataract surgery services. Conclusion: Couching remains a significant challenge in Nigeria. The outcomes of cataract surgery are poor with the lack of aphakic correction being the main cause of the poor outcomes. [ABSTRACT FROM AUTHOR]- Published

Purpose: To estimate the prevalence of low vision and blindness, identify the causes, and suggest policies for an effective eye care program based on 2005 data from Sokoto State, Nigeria. Materials and Methods: A stratified two-stage cluster sampling method was used to quantify the prevalence of blindness and the causes from 4 health zones in Sokoto State. Subjects were evaluated using a magnifying loupe, direct ophthalmoscope and torchlight. Data were collected based on the World Health Organization prevention of blindness coding for an eye examination. Prevalences with 95% confidence intervals (CI) were calculated and surgical coverage for causes of blindness was also analyzed. Results: The response rate was 91%. The prevalence of bilateral blindness was 1.9% (95% CI: 1.5-2.3%) ranging from 1.6% to 2.0% across the four health zones. The prevalence was 2.1% (95% CI: 1.6-2.6%) in males and 1.6% (95% CI: 1.1-2.1%) in females. The leading cause of bilateral blindness was cataract (51.6%), followed by uncorrected aphakia (20.9%) and glaucoma (11%). The prevalence of bilateral operable cataract was 1.9% (95% CI: 1.5-2.3%). The cataract surgical coverage (individuals with visual acuity <6/60) for the study was lower than the couching coverage (4.4% vs. 14.9%, respectively). Surgical coverage for trichiasis was 4.4%. The major barrier to cataract and glaucoma management was cost. Conclusions: The prevalence of blindness in Sokoto State is high yet the main causes are largely avoidable. Barriers can be reduced by appropriate health education regarding the eye care program and the provision of integrated, sustainable, affordable and equitable services. [ABSTRACT FROM AUTHOR]

Purpose: To characterize the demographic and psychosocial problems of a group of blind people as a way of attracting more attention to and providing data that can improve the psychosocial care of the visually impaired. Materials and Method: A cross-sectional descriptive study of a population of totally blind people in Ilorin, Nigeria using a self-report questionnaire (SRQ). The questionnaire was verbally administered by the study personnel in the local language. Simple frequency tables were obtained and the Chi-square test was performed to determine significant differences between variables. P-value <0.05 was considered statistically significant. Results: Sixty one blind patients consented to participate. Most participants were engaged in street begging for their livelihood. Most subjects desired a job change, signifying dissatisfaction with the present occupation. Up to 80% of the cohort was married and had spouses who were also blind in at least one eye. Approximately two-thirds had five or more children and majority lived with family members who were responsible for taking care of their personal hygiene, cooking and mobility. The majority developed blindness in childhood and 16% had a family history of blindness and 77% had never used conventional eye care, with corneal disease being the most frequent cause of blindness. Many feared that their children may also become blind. Thirty-one (51%) scored =5 on SRQ and were classified as probable cases of psychological disorder. Conclusion: Blindness in a majority of cases that started in childhood was probably preventable. Inaccessibility to or failure of the formal rehabilitation and social welfare systems may have caused this psychosocial dilemma. The high level of social and family interaction provides opportunity for organized preventive ophthalmology, community health care services and psychosocial care. [ABSTRACT FROM AUTHOR]

Objective: To determine the contribution of corporal punishment to ocular morbidity and visual impairment in Nigerian children. Materials and Methods: A prospective study was conducted of all patients aged 0- 15 years seen with ocular injuries over a four year period. Those who sustained ocular injuries during the administration of corporal punishment were further studied. Relevant information was documented using a semistructured questionnaire. Data was analyzed by simple descriptive statistics using SPSS statistical package version 10. Results: A total of 186 children were seen within the study period. Eighty-nine (47.8%) had ocular injuries and 27 (30.3%) had ocular injuries resulting from corporal punishment. Of the latter group, eighteen were males and nine were females. Their ages ranged from 3-15 years (mean = 8.5 ± 2.4 years). Corporal punishment-associated injuries occurred most commonly as seen in 17 (63%) of our study population who were aged 7-12 years. These 27 cases of injuries were sustained in the schools: 13 (48.2%), homes: eight (29.6%), market place: three (11.1%), workshop: two (7.4%) and worship houses: one (3.7%). A stick was the object mostly implicated in causing ocular injuries in 13 (48.2%) followed by a belt in five (18.5%) and a whip in four (14.8%). Severe visual impairment occurred in two (7.4%) patients while blindness occurred in three (11.1%) patients. Conclusion: Corporal punishment is a major cause of ocular morbidity and blindness in Nigerian children. [ABSTRACT FROM AUTHOR]
