5 Fluorouracil versus mitomycin-c as adjuncts to conjuctival autograft in preventing pterygium recurrence
(Springer, 2012) Bekibele, C. O.; Ashaye, A.; Olusanya, B.; Baiyeroju, A.; Fasina, O.; Ibrahim, A. O.; Ogun, O.
To compare the efficacy of 5-fluorouracil (5-FU) with mitomycin C (MMC) in preventing pterygium recurrence when used as an adjuvant following pterygium excision with conjunctival autograft. Low-dose MMC combined with conjunctival autograft is an effective treatment for preventing recurrence following pterygium excision, but safety, cost, and availability limit its use in developing countries. There is a paucity of data on the efficacy of 5-FU when used in Africa as an adjuvant to conjunctival autograft following pterygium excision. This is a randomized controlled prospective trial using either 50 mg/ml 5-FU or 0.01% MMC. Eighty eyes of 80 subjects were studied. Forty-six subjects with a mean age 49.8 ± 13.8 years were treated with 5-FU (USD 13.0 per unit), while 34 patients with a mean age 51.9 ± 12.1 years were treated with MMC (USD 20.0 per unit). There was no significant difference in mean age between the two groups (p = 0.48). The ratio of male to female patients in both groups was similar at 0.92:1 for the 5-FU group and 1:1 for the MMC group (p = 0.85). Mean follow-up period was 35.2 ± 29.1 weeks. Recurrence rate in the 5-FU group was 8.7% compared to 11.8% in the MMC group (recurrence risk ratio = 0.71, 95% CI 0.17-3.1, p = 0.7). One patient from the MCtreated group had corneoscleral melting. Other complications were mild and not sight threatening. In the prevention of pterygium recurrence, 5-FU appears to compare favorably with low-dose MMC when used as an adjuvant following pterygium excision and conjunctival autograft. Further studies are required to assess the long-term effect of using 5-FU in such cases.

Management of childhood cataract: practice patterns among ophthalmologists in Nigeria
(Springer, 2023-09) Ugalahi, M.; Adedira, O.; Olusanya, B.; Baiyeroju, A.
OBJECTIVE: To describe the practice patterns for the management of paediatric cataracts among ophthalmologists practising in Nigeria. METHODS: A cross-sectional study of fully trained Nigerian ophthalmologists who perform cataract surgery in children aged 16 years and below. An online questionnaire was distributed via e-mail and social media platforms to respondents. Data on socio-demographic characteristics, type, location and years of practice, status and preferred approach to management of childhood cataracts were obtained and analysed. RESULTS: =A total of 41 ophthalmologists responded that they perform paediatric cataract surgery. Of these, 25 (61.0%) were paediatric ophthalmologists while 7(17.0%) were general ophthalmologists. Most respondents (92.7%) practise in urban settings and 30(73.2%) work in tertiary hospitals. Most respondents (90.2%) routinely insert intracular lenses (IOLs) in children aged 2 years and above while 32(78.0%) routinely under-correct the IOL power. Thirty-four (82.9%) have an anterior vitrectomy machine, 31 (75.6%) routinely perform posterior capsulotomy and anterior vitrectomy, and 17 (58.5%) routinely perform same-day sequential bilateral cataract surgery. Twenty-six respondents (63.4%) respondents routinely give near correction in aphakic children, while 24 (58.5%) respondents routinely give bifocals in pseudophakic children. Compared to other sub-specialists, paediatric opthalmologists were 24 times more likely to routinely under-correct IOL power (p=0.001) and 4 times more likely to routinely correct near vision in aphakic children (0.036) as well as prescribe bifocals for pseudophakic children respectively (0.029). CONCLUSION: The practice of paediatric cataract surgery in Nigeria is mainly in line with expected standards, but there is a need for the development of detailed practice guidelines.
Management of primary childhood glaucoma: evaluation of practice, practice gaps, and needs in a low‑resource country
(Wolters Kluwer - Medknow, 2024) Ugalahi, M.||||||||A. | ||; Sarimiye, T. F.; Obajolowo, T.; Nkanga, E. D.; Abdulrahman, A.; Olusanya, B.; Baiyeroju, A.
Purpose: To evaluate the current practice, equipment availability, and training needs for managing childhood glaucoma in Nigeria. Materials and Methods: An online questionnaire (Google Forms) was distributed through E-mails and social media platforms of pediatric ophthalmologists and glaucoma specialists who practice in Nigeria and manage glaucoma in children aged 0–16years. Information concerning sociodemographic characteristics, type of practice, location of practice, years of practice, status, and preferred practices in the management of childhood glaucoma cataracts were obtained and analyzed with SPSS. Results: Thirty (23.3%) out of 129 eligible participants indicated they perform glaucoma surgeries in children. The majority (66.6%) had practiced as specialists for 10years or less, and 70% were pediatric ophthalmologists. A third of the respondents practiced in the country’s southwest region, with none in the Northeast region. The most common surgery performed for primary congenital glaucoma was combined trabeculotomy trabeculectomy, while trabeculectomy was the most common surgery performed for juvenile open-angle glaucoma. Two respondents reported performing glaucoma drainage device surgery and seven reported possessions of skills for goniotomy. All centers had trabeculectomy instrument sets, while three centers had facilities for endolaser cyclophotocoagulation, and only two centers had knives for goniotomy. Antimetabolites were routinely used for childhood glaucoma surgeries by 26(86.7%) respondents, and the most common antimetabolite used was mitomycin (21; 80.8%). Conclusion: There is a need for the development of in-country training programs and the exchange of skills through collaboration among those providing glaucoma services within Nigeria to improve the care of children with glaucoma.
