RESUMO
AIM: To evaluate the quality of life (QOL) and level of depression among participants with high myopia in Nigeria and the demographic factors associated with these outcomes. METHODS: This cross-sectional study was conducted on 100 adult participants with high myopia (defined as refractive error ≤-5.00 D or worse, and uncorrected visual acuity worse than 6/18 in the better seeing eye) attending ophthalmology centres in Nigeria from 2 October 2021 to 30 August 2022. The means and standard deviations were calculated for each of the four domains of World Health Organization Quality of life scale (WHOQOL-BREF) using the transformed scores. The Beck Depression Inventory (BDI) scale was used to assess the level of depression. RESULTS: The highest and the lowest mean scores of WHOQOL-BREF domains were found for the psychological and physical health domains (mean percentage scores were 67.0 [95% confidence intervals (CI) 64.1-68.9] and 55.3 (95%CI 51.8-58.8, P<0.001), respectively. One-way analysis of variance (ANOVA) revealed significant differences in physical health with educational status (higher among those with tertiary education: mean difference 0.9, 95%CI -0.2-2.1; P=0.049), differences in psychological health with working status (higher among those who were working 1.2, 95%CI 0.3-2.1; P=0.012). Also, the result showed a statistically significant association between environmental health and marital status (higher among non-married: 1.7, 95%CI -0.9-2.3; P=0.012) while overall health was associated with place of residence (higher in urban areas: 2.3, 95%CI 1.2-3.5; P=0.024). For depression, one in every nine participants reported major depressive symptom, mostly younger people (aged 16-29 vs 30-49y: 17.0% vs 0, P=0.019), and slightly more women than men (14.3% vs 0, P=0.064). There were significant negative correlations between the depression scores and psychological health (r=-0.48, P<0.001), physical health (r=-0.29, P=0.002), social and relationship (r=-0.49, P<0.001), environmental (r=-0.48, P<0.001) and overall health (r=-0.49, P<0.001). CONCLUSION: People with high myopia have a relatively moderate QOL, but poor physical health, particularly the younger age group, and women who are more likely to experience clinically relevant depression. Eye care professionals should consider possible referrals for counselling for people with high myopia.
RESUMO
Aim: To determine the causes of tractional retinal detachment (TRD) in Nigerians. Materials and Methods: A prospective, multicentre study evaluating eyes diagnosed to have TRD. History, clinical examination (including visual acuity, intraocular pressure measurement, anterior segment examination and dilated fundoscopy) and systemic evaluation (including previous diagnosis of diabetes, hypertension, sickle-cell disease and others) were performed in TRD eyes out of a cohort of retinal detachment eyes. Results: The prevalence of TRD of the 237 patients diagnosed with RD within a one-year study period was 25.7% (61 patients). Eighty eyes were diagnosed with TRD. Thirty-eight eyes of nineteen patients (31%) were bilateral, and 42 (69%) were unilateral. There were 38 male patients (62.3%) and 23 female patients (37.7%). The mean age was 52.3 ± 12.7 years (11-69 years). 88.5% of all TRD patients had an associated systemic disease, diabetes being the most common disease in 88.8% of them. Proliferative diabetic retinopathy was the most common cause of TRD (77.5%) and the most common cause of bilateral TRD. Both trauma and proliferative sickle-cell retinopathy occurred in 3.8% of the eyes. 68.8% of TRD eyes were blind at the presentation. However, the causes of TRD did not show any significant association with blindness (P = 0.819). Conclusion: Proliferative diabetic retinopathy poses a significant threat to vision, being the most common cause of TRD. Early detection and treatment of proliferative retinopathy in diabetes and sickle-cell disease, and trauma prevention will significantly reduce the burden of blindness due to TRD.
RESUMO
Background: Exudative retinal detachment (ERD) is a rare type of retinal detachment (RD), and information on its causes and presentation in Nigerians and Black Africans is scarce. Aim: To report the prevalence, vision at presentation, and causes of ERD in a cohort of RD patients. Materials and Methods: A prospective, multicentre, hospital-based study. We examined consecutive eyes diagnosed with ERD in ophthalmic patients seen within 1 year in four ophthalmic hospitals in Nigeria. The patients had a complete eye examination, including visual acuity, intraocular pressure measurement, slit lamp examination of the anterior segment, dilated fundus examination, and other ancillary investigations. Statistical analysis was done using SPSS version 22.0. Results: Nine out of 237 patients were diagnosed with ERD, giving a hospital-based prevalence of 3.8% of RDs. The mean age of patients was 45.8 ± 21.6 years (6 months-80 years), male:female = 2:1. ERD was bilateral in one patient and unilateral in eight patients. There was no gender association (P = 0.84), but systemic disease was associated with a risk of ERD (P = 0.001). Five out of 9 (55.6%) patients had an associated systemic disease. The systemic diseases include two patients (40%) who had chronic renal failure, two patients (40%) who had systemic hypertension, and one patient (10%) who had lung cancer. Other ocular causes of ERD include post endophthalmitis, coats disease, and age-related macular degeneration in one eye each. 80 % of eyes were blind at presentation. Conclusion: ERD is a rare form of RD in Nigerians and is associated with systemic diseases. There are inflammatory, neoplastic, vascular, and degenerative causes of ERD. At presentation, most eyes are blind. Early presentation will be beneficial in salvaging vision. Also, awareness of the occurrence and causes of ERD should be created amongst eye care practitioners.
RESUMO
Background: Retinopathy of prematurity (ROP) is an important cause of childhood blindness worldwide. This blindness is avoidable through regular screening of preterm infants and prompt intervention for those with the condition. Aims/Objectives: This study aimed to determine the pattern of presentation of ROP and the risk factors for its development among preterm infants in the Neonatal Unit of the University of Calabar Teaching Hospital, Calabar, Nigeria. Design of Study: This study is a prospective, longitudinal study. Settings: The study was carried out in the Special Care Baby Unit, Sick Baby Unit, and Neonatal Clinic of the Department of Paediatrics and Child Health, University of Calabar Teaching Hospital, Calabar, Nigeria. Materials and Methods: All preterm infants whose mothers had given informed consent to participate were enrolled. Ocular examination was performed by a trained ophthalmologist. ROP was staged and documented using the revised version of the International Classification of ROP. Data were entered into a questionnaire and analysed using IBM SPSS version 22. Results: Of the 53 neonates recruited into the study, ROP was detected in 11 (21%) neonates, of which 9 (82%) had stage 1 disease, 2 (18%) had stage 2, and none had stage 3. ROP was more common in females, 7 (63.6%), than their male counterparts 4 (36.4%). ROP was higher among those with gestational age (GA) ≤30 weeks [9 (81.8%)] when compared with those with GA >30 weeks [2 (18.2%)] (P = 0.016). Other risk factors for ROP assessed by this study were found not to be significantly associated with the occurrence of ROP. Conclusion: ROP was present in 21% of the neonates, and the majority had stage 1 disease. This finding emphasizes the need for screening of all preterm neonates for ROP in order to forestall avoidable blindness which could result from this condition.
