A review of vitreoretinal surgeries done at Kenyatta National Hospital
Abstract
Objective: To review vitreoretinal surgeries done at Kenyatta national hospital (KNH)
between 1st October 2000 to 30th September 2007.
Design: Retrospective case series.
Setting: Kenyatta National Hospital, the national referral hospital in Kenya
Subjects: All cases of vitreoretinal surgery done from 1st October 2000 to 30th September
2007.
Main outcomes: The main indications for vitreoretinal surgery, procedures performed
during vitreoretinal surgeries, visual outcomes and complications related to vitreoretinal
surgeries at KNH.
Results: 297 cases were done within the study period, with 267(89.9%) medical records
retrieved. Most eyes (79.8%) had a single operation. More right eyes (54.7%) were
operated compared to left eyes.59.9% of the eyes oJ>eratedhad symptoms for more than 3
months. The mean age of presentation was 45.5 years, range was 3-82 years and peak age
was 56-65 years. Vitreous hemorrhage was the main indication (43.8%) for vitreoretinal
surgery with diabetic retinopathy contributing 47.0% of all the cases of vitreous
hemorrhage, rhegmatogenous retinal detachment contributed 41.6% of all vitreoretinal
cases done. Pars plana vitrectomy was the main procedure done, performed in 79.8% of
all the cases. Visual acuity improved in 70.8% of all the operated cases. Those who
presented late were less likely to have an improved visual acuity (p=0.040). Intraoperative
complications were noted in 16.1% while immediate post-operative
complications in 19.9% and late post-operative complications in 9.7% of all the cases
done ..
Conclusion: Vitreous hemorrhage and rhegmatogenous retinal detachment were the main
indications for vitreoretinal surgery, most patients presented late for surgery, pars plana
vitrectomy was the main vitreoretinal procedure done, most patients had an improved
visual acuity and duration of symptoms affected visual acuity.
