Pterygium surgeries at a tertiary hospital, southwest Nigeria: a four-year review

Background: Over the years several pterygium surgical techniques have been developed with the aim of having the least possible recurrence rate. This has been from bare sclera excision which had an unacceptable recurrence rate to the current use of conjunctiva autograft with or without various adjuncts. This study was to review the current practice in a typical multi-specialist ophthalmic department. Method: The ophthalmic theatre operating register was retrospectively reviewed to obtain information on all patients who had pterygium excision at the University College Hospital, Ibadan, over a 4-year period from January 1, 2014, to December 31, 2017. Results: A total of 324 pterygium surgeries were performed and final analysis was on 249 (76.9%) surgeries which met the inclusion criteria, male to female ratio of 0.96:1. The commonest surgical technique was excision + 5-Flourouracil (5FU) + conjunctival autograft accounting for 187(75.1%) eyes. In total, postoperative recurrence was recorded in 40 (16.1%) eyes. The subgroup of excision + 5FU + autograft had the least recurrence rate of 18 (9.6%) eyes. Conclusion: A significant majority of the excision was with conjunctiva autograft with an acceptable low recurrence rate compared with most studies

Cataract surgery in Ibadan, Nigeria: Visual outcome and post-operative refractive error

Background: Cataract is the leading cause of blindness worldwide and can be treated by various surgical techniques with good visual outcome.Objective: To describe the visual outcome and post-operative refractive status among patients who had cataract surgery in a tertiary centre.Methods: In a retrospective study, the demographic data, type of cataract, surgical procedure and complications, visual outcome and post-operative refractive status of the treated eye were retrieved from the hospital records of all adult patients who had cataract surgery.Results: Four hundred and sixty eyes of 456 patients (mean age 61.2 ± 17.3 years, Male: Female = 1.1: 1) had cataract surgery during the study period January 2012 and December 2014. The pre-operative visual acuity was < 3/60 in 415 (90.2%) eyes. All the surgeries were performed under local anaesthesia with 331 (72%) eyes undergoing extracapsular cataract extraction while 129 (28%) had small incision cataract surgery. Visual outcome in those who had a minimum of six weeks follow-up revealed unaided visual acuity of ≥ 6/18 in 185 (56.9%) eyes. Following refraction, 237 (72.9%) eyes had acuity of ≥ 6/18. Post-operative spherical refractive error ranged from ­6.75D to +4.50D (mean -1.61 ± 1.41D) while cylindrical error ranged from 0.00DC to 6.00DC (mean 2.33 ± 1.80DC). Pre-existing ocular problems contributing to poor post-operative visual outcome included glaucoma (50; 15.4%), and age-related macular degeneration (10; 3.1%). Conclusion: Extracapsular cataract extraction gave better visual outcome compared with small incision cataract surgery, but a higher incidence of post-operative cylindrical error was observed
