Retinal detachment in patients with acquired immunodeficiency syndrome

Abstract

Cytomegalovirus retinopathy is the most frequent opportunistic infection of the eye in patients with acquired immunodeficiency syndrome (AIDS). We studied 71 patients with cytomegalovirus retinopathy (n = 69) or acute retinal necrosis (n = 2) with respect to the frequency and management of retinal detachment. Retinal detachment was seen in 14 patients (relative frequency, 19.7%). In 2 patients, the retinal detachment was bilateral. In 5 patients, pars plana vitrectomy and silicone-oil tamponade was performed, and in 1 of these patients scleral buckling was applied before vitrectomy. In 3 other patients scleral buckling was performed, and 1 of these individuals had sulfur-hexafluoride injection. In 8 eyes (6 patients), retinal detachment occurred in eyes with completely burned-out retinopathy without relevant function, and no surgical treatment was performed. Long-term retinal reattachment was seen in all 5 patients undergoing pars plana vitrectomy with silicone-oil tamponade. Visual acuity was preserved until the last follow-up in 4 of these 5 patients. In the patients undergoing a buckling procedure alone, no anatomic or functional success was observed. During vitrectomy, reduced retinal vascular perfusion and blood-flow sludging was observed in 2 patients. As the duration of survival of patients with AIDS and cytomegalovirus retinopathy or acute retinal necrosis is increasing, more cases of retinal detachment will be observed. Overall, 5% of patients with AIDS are expected to develop retinal detachment. In conclusion, treatment of cytomegalovirus-associated retinal detachment by pars plana vitrectomy with silicone-oil tamponade seems to be successful and safe and may maintain the patient's quality of life.
