ABSTRACT
Purpose
To report a case series of human immunodeficiency virus (HIV)-negative patients with healed cytomegalovirus retinitis presenting with proliferative retinopathy (in the form of neovascularisation elsewhere).
Methods
Retrospective case series. Multimodal imaging was performed at each follow-up visit.
Results
Three patients with non-HIV immune dysfunction were followed up after healing of CMV retinitis. All three developed neovascularisation. Patient 1 after 4 months presented with vitreous haemorrhage for which pars plana vitrectomy was performed. Patient 2 developed neovascularization at disc and neovascularisation elsewhere 4 months after resolution, and patient 3 despite being affected by bilateral CMV retinitis, presented with unilateral neovascularization at 14 month after resolution of retinitis.
Conclusion
Increased incidence of this rare entity could be attributed to partial immune dysfunction in non-HIV patients, limited area of retinitis with a more aggressive occlusive vasculitis. Extensive occlusion with more area of viable retina for angiogenic factor production explains this phenomena. It emphasizes the need for continued follow-up even after healing and to differentiate it from reactivation of retinitis and immune recovery uveitis.Abbreviation: CMV: cytomegalovirus; HIV: human immunodeficiency virus; BCVA: best corrected visual acuity
