title: Immune recovery uveitis in AIDS patients with cytomegalovirus retinitis treated with highly active antiretroviral therapy in Venezuela.
abstract: OBJECTIVE
  To determine the characteristics of immune recovery uveitis (IRU) in acquired immunodeficiency syndrome (AIDS) patients with inactive cytomegalovirus (CMV) retinitis who responded to highly active antiretroviral therapy (HAART) in a Venezuelan population.
  
  
  METHODS
  We examined 34 patients (50 eyes) with AIDS (HAART responders) and healed CMV retinitis. Patients were observed for a median of 19.3 months following an increase in the CD4 cell count. Ten eyes were treated with sub-Tenon space corticosteroid injections. An age-matched control group of patients with healed CMV retinitis who did not have IRU (30 eyes of 20 patients) was included to compare CMV surface area and complications.
  
  
  RESULTS
  We found that 12 (37.5%) of 32 HAART responders developed IRU (18 eyes). The clinical findings of these 18 eyes with IRU are presented. The clinical spectrum of inflammation included vitritis, macular edema, epiretinal membranes, anterior uveitis, macular hole, retinal detachment with proliferative vitreoretinopathy, and cataract. Eyes with IRU had a mean CMV surface area of 31.7%. However, eyes without IRU (control group) had a mean CMV surface area of 35% (P = 0.41). Periocular treatment resulted in vision improvement (in 90% of eyes) without reactivation of retinitis.
  
  
  CONCLUSIONS
  Symptomatic IRU developed in a significant number of patients with CMV retinitis following successful HAART in a Venezuelan population. CMV surface area does not seem to be a risk factor for the development of IRU. Eyes with IRU respond favorably to antiinflammatory therapy without reactivation of retinitis.
