Foveal Retinal Detachment Diagnosed by Optical Coherence Tomography after Successful Retinal Detachment Surgery

Purpose: To investigate the time course and occurrence of foveal retinal detachment presenting with symptoms of metamorphopsia and decreased visual acuity after successful surgery for macula-off retinal detachment. Methods: This study included 9 eyes of 9 patients who were diagnosed with foveal retinal detachment using optical coherence tomography (OCT) among 198 patients who had decreased visual acuity and metamorphopsia after successful rhegmatogenous retinal detachment surgery. Results: All eyes were diagnosed with foveal retinal detachment by OCT. Foveal retinal detachment occurred after scleral buckling surgery in 8 eyes (88%) and after vitrectomy and pneumoretinopexy in 1 eye. The degree and frequency of foveal retinal detachment was milder and lower after vitrectomy and pneumoretinopexy than after scleral buckling surgery. All foveal retinal detachments were reattached spontaneously after 9 months (range, 5～14 months). In all eyes, the symptom of metamorphopsia was improved and visual acuity increased after the foveal retinal detachment was reattached. Conclusions: OCT can be used to diagnose foveal retinal detachment in cases when the fundus and fluorescein angiography do not show specific findings but, presenting symptoms of decreased visual acuity and metamorphopsia. In all cases evaluated, the foveal retinal detachment was reattached spontaneously without treatment.
