Ultrasonographic differentiation of the peripheral choroidal detachment from the circumferential scleral buckle

摘要

A 40-year-old male patient presented with a history of surgery in the left eye for retinal detachment 1 year ago. His history of medical and surgical interventions was incomplete as the patient lost all his previous records. On examination, visual acuity was 20/20 in the right eye and hand movement close to face with accurate projection of rays in the left eye. Both eye corneas were clear with normal anterior chambers. The right eye had a clear lens, and the fundus was within normal limits. Whereas in the left eye, a total cataract was present. This hindered the retinal evaluation. Intraocular pressures were 18 mm Hg in the right eye and 14 mm Hg in the left eye. To assess the posterior segment, a B scan ultrasonography was performed which revealed a thick convex mount towards the vitreous cavity giving an appearance of shallow choroidal detachment.
