RETINAL DETACHMENT ASSOCIATED WITH PERIPAPILLARY STAPHYLOMA IMAGED WITH SWEPT SOURCE OPTICAL COHERENCE TOMOGRAPHY

PURPOSE: To examine a rhegmatogenous retinal detachment (RRD) associated with a peripapillary staphyloma with swept source optical coherence tomography (SS-OCT) before and after vitrectomy and circumferential photocoagulation. METHODS: The SS-OCT images including the montage images of two patients with a RRD associated with peripapillary staphylomas were analyzed. A 34-year-old woman (Case 1) and a 70-year-old woman (Case 2) both noticed temporal visual field defects in their left eyes. Ophthalmoscopy showed a retinal detachment in the nasal quadrant without any peripheral breaks in both patients. The best-corrected visual acuity was 20/20 with -8.5 diopters in Case 1 and 20/25 with -7.0 diopters and moderate cataract in Case 2. SS-OT was used to follow the clinical course of the RRD. RESULTS: Preoperatively, retinal tears were detected nasal to the optic disk within the excavated staphyloma in the SS-OCT images. A posterior vitreous detachment was not present in Case 1 but was present in Case 2. The glial tissue at the edge of the excavated staphyloma was removed from both eyes, and the subretinal fluid was drained internally through the retinal breaks. Hemicircumferential photocoagulation was performed at the nasal edge of the staphyloma, and the retina was reattached in both eyes. Postoperative SS-OCT montage images showed retinal reattachment but a detachment was still present within the staphyloma. CONCLUSION: Vitreous surgery was effective for an RRD associated with a peripapillary staphyloma. Examinations by SS-OCT can follow the changes in the RRD and the excavated lesion of a peripapillary staphyloma.
