Item Retinopathy of prematurity in a tertiary facility: an initial report of a screening programme(Paediatric Association of Nigeria, 2020) Olusanya, B. A.; Oluleye, T. S.; Tongo, O. O.; Ugalahi, M. O.; Babalola, Y. O.; Ayede, A. I.; Baiyeroju, A. M.Retinopathy of prematurity (ROP) screening in Nigeria is at a nascent stage and at the moment there are no National guidelines for ROP screening in Nigeria. Thus it is desirable for screening programs to report findings amongst screened preterm infants in order to facilitate the development of national ROP screening criteria and guidelines. The aim of this report is to describe the frequency, severity and risk factors for retinopathy of prematurity (ROP) among preterm and very low-birth-weight babies screened within the first year of initiating an ROP screening program at a Nigerian tertiary facility. Methods: A cross-sectional study of infants born at less than 34 weeks gestational age; or with birth weight less than 1500g between May 2016 and May 2017. ROP screening examinations were performed by ophthalmologists with the use of an indirect ophthalmoscope, after pupillary dilation, in collaboration with the neonatology team. Information on gestational age at birth, birth weight, oxygen therapy and presence of other risk factors were recorded and analyzed. Results: A total of 74 infants were screened during the period. There were 36 (48.6%) males. Mean gestational age at birth was 29.6 (±2.35) weeks. Mean birth weight was 1.26 (±0.27) kg with a range of 800 to 1950g. ROP was detected in 9 (12.2%) infants. Two (22.2%) of these had Threshold ROP. There was no significant difference between the mean birth weight and mean gestational age of the infants who had ROP compared to those without ROP. The two infants with Threshold ROP were treated with intravitreal Bevazicumab and had regression of ROP. Conclusion: Retinopathy of prematurity was diagnosed in at risk infants in this facility. There is, therefore, a need to establish ROP screening programs in all neonatal units across the country. In addition, established programs need to evaluate their screening criteria with a view towards developing country-specific screening guidelines.Item Pterygium treatment using 5-FU as adjuvant treatment compared to conjunctiva autograft(Nature Publishing Group, 2008) Bekibele, C. O.; Baiyeroju, A. M.; Olusanya, B. A.; Ashaye, A. O.; Oluleye, T. S.Background The use of conjunctiva autograft, adjunct antimetabolite therapy has been shown to be effective in preventing pterygium recurrence. Objective To compare 5 fluorouracil (5-FU) to conjunctival autograft in the treatment of large, fleshy pterygium. Methods A randomised controlled prospective study of outcome of pterygium treatment using 5-FU as adjuvant treatment compared to conjunctiva autograft. Thirty-five eyes with large pterygium treated with bare sclera conjunctival excision plus 5-FU were compared with 33 eyes treated with excision and conjunctival autograft alone. Results Post-operative pterygium recurrence was observed in four (11.4%) eyes treated with 5-FU and 4 (12.1%) eyes treated with conjunctiva autograft (P40.05). The post-operative complications included, granuloma formation 11.4% for 5-FU and 3.0% for autograft and conjunctival discharge 5.7% for 5-FU group only. Conclusion 5-FU is marginally superior to conjunctival autograft in the prevention of pterygium recurrence but neither gives a more desirable single digit recurrence rate. Randomised studies combining both conjunctival autograft and 5-FU in pterygium treatment is advocated to further explore their effect.Item Pterygium treatment using 5-FU as adjuvant treatment compared to conjunctiva autograft(Nature Publishing Group, 2008) Bekibele, C.

Results: Post-operative pterygium recurrence was observed in four (11.4%) eyes treated with 5-FU and 4 (12.1%) eyes treated with conjunctiva autograft (P>0.05). The post-operative complications included, granuloma formation 11.4% for 5-FU and 3.0% for autograft and conjunctival discharge 5.7% for 5-FU group only. Conclusion: 5-FU is marginally superior to conjunctival autograft in the prevention of pterygium recurrence but neither gives a more desirable single digit recurrence rate.

M.; Bekibele, C. O.; Bamgboye, E. A.; Omokhodion, F.; Oluleye, T. S.To obtain epidemiological data on the prevalence and risk factors for open angle glaucoma in hospital workers of African origin, and investigate appropriate methods of a rapid, cost-effective screening procedure for glaucoma. A cross-sectional study of workers in the University College Hospital (UCH) Ibadan, using a structured questionnaire for data collection. The variables available for data analysis include workers demographic characteristics, visual acuity, pupil status, intraocular pressure, cup-disc ratio, central visual fields, family history of glaucoma, chronic diseases such as hypertension and diabetes. The data was analysed with EPI-INFO version 6.02 for simple analysis, while the SPSS package was used for multivariate analysis. A total of two thousand, one hundred and nine (2, 109) UCH workers participated in the screening exercise for glaucoma. A high majority of the workers 1794 (85.1 %) were negative to the diagnosis of glaucoma, while the remaining 315 (14.9%) were suspected to have glaucoma out of which 57 (2.7%) were confirmed as definite glaucoma cases. The prevalence of glaucoma among UCH workers was 27 per 1000, 95%, confidence interval = 20 per 1000,35 per 1000. Factors associated with glaucoma were relative afferent pupillary defect, cup-disc ratio greater than 0.7, intraocular pressure, family history of glaucoma and the presence of chronic diseases such as diabetes. The left eye appears to have a higher probability of ocular problems compared with the right eye. The prevalence of glaucoma among hospital workers was 2.7% The cup-disc ratio appears to be a better diagnostic tool for glaucoma since it gives the best positive predictive value (with a cut-off point of 0.7) than all other variables.
