STRAWBERRY RETINA: SILICONE OIL-RETINA INTERFACE ON MULTIMODAL IMAGING.

Abstract

To report a new photographic macular feature identified on multimodal imaging in eyes with silicone oil in situ. Retrospective, observational case series of three eyes of three patients. Two eyes had undergone initial vitrectomy for vitreous hemorrhage with fibrovascular membranes causing tractional retinal detachments secondary to retinovascular occlusion. One eye had further vitrectomy for rhegmatogenous retinal detachment complicated with proliferative vitreoretinopathy. All three eyes had multiple, discrete, coarse, hyperreflective deposits at the silicone oil-retina interface on optical coherence tomography macular scans, with increased reflectivity from the inner retinal layers. On multicolor and infrared images, these preretinal deposits produced hyporeflective darker spots giving a quasi-pitting appearance of the retinal surface against glossy bright reflection from silicone oil, thus simulating an appearance of ‟a strawberry." These deposits are causing inverse pitting of the oil bubble. On blue autoflourescence imaging, the preretinal deposits caused hypoautoflourescence. Partial silicone oil emulsification was seen superiorly in two of these patients with a different clinical and optical coherence tomography appearance from these hyperreflective macular deposits. We describe a new distinctive ‟Strawberry Retina" appearance identified on multicolor and infrared macular images associated with hyperreflective, coarse deposits at the silicone oil-retina interface.
