“…Choroidal detachment is a significant posterior segment pathology which needs a definite diagnosis before proceeding for any form of ocular interventions. B scan ultrasound is a useful tool to assess the far peripheral retinal pathologies along the lateral longitudinal view 1. The choroidal mount will have a double spike with convexity towards the vitreous with or without any suprachoroidal collections.…”

DesCripTionA 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.To differentiate choroidal detachment from other misleading conditions, we followed few steps. First, the typical picture of choroidal detachment was studied ( figure 1A) and in the confounding case (figure 1B) when the probe was rotated obliquely, the convex-shaped mount lost its convexity ( figure 1C) which is not observed in choroidal detachment. Second, to redefine the cause, the choroidal thickness along the attached portion was measured which was around 0.7 mm ( figure 1D). Similarly, the thickness of the convex mount was
