Objective : To evaluate the efficacy and results of pars plana vitrectomy with endotamponade for retinal
detachments caused by necrotizing retinitis in HIV patients.
Materials and Methods : The data of patients with HIV-related retinal detachment who underwent pars plana
vitrectomy with silicone oil or gas endotamponade between January 2003 and June 2005 were retrospec-
tively reviewed. The outcome measures were demographic data, anatomical, and visual results.
Results : Of all 24 eyes from 20 patients, 19 eyes underwent pars plana vitrectomy with silicone oil tamponade
and 5 eyes with long-acting gas tamponade. Mean follow up time was 13 months (range 2-33 months). The
overall anatomical success was 83% (84% and 80% with silicone oil and gas tamponade, respectively). Final
best corrected visual acuity was equal or better than 5/200 in 12 eyes (50%). Forty-six percent had stabled or
improved vision at the end of follow-up.
Conclusion : Pars plana vitrectomy with silicone oil or gas tamponade gives the high anatomical success rate
in the repair of retinal detachments caused by necrotizing retinitis in HIV patients. There were the same
reattachment rate and visual results between the two tamponade groups. However, the use of gas tamponade
may be effective in patients with highly active antiretroviral therapy (HAART).
