Exudative retinal detachment due to small noncalcified retinal astrocytic hamartoma

Abstract

Purpose To report a case of exudative retinal detachment due to small noncalcified retinal astrocytic hamartoma and review pertinent literature. Design Case report and review of literature. Methods Clinical examination, fluorescein angiography, optical coherence tomography, and laser treatment were performed. Results Exudative macular detachment caused by a small noncalcified retinal astrocytic hamartoma confirmed by optical coherence tomography regressed completely after laser therapy. Visual acuity improved only slightly because lamellar macular thinning developed after subretinal fluid and macular exudates resolved. Conclusions Small noncalcified, parafoveal retinal astrocytic hamartomas may cause macular retinal detachment. Optical coherence tomography may aid in the diagnosis of the tumor. Argon laser photocoagulation may induce tumor regression and resolution of exudative detachment. Final visual acuity may be limited in some cases.
