ABSTRACT
To evaluate the specifity and sensitivity of ocular sonography in the diagnosis of retinal detachment in the presence of vitreous hemorrhage. This cross-sectional study included 47 [23 right eyes and 24 left eyes] eyes of 47 patients [18 male and 29 female subjects] with vitreous hemorrhage suspected of retinal detachment requiring surgery. Preoperative ocular sonography was compared with intraoperative findings to determine the sensitivity and specifity of ocular sonography. Mean age of the patients was 43.8+23.1 years [range 4 months to 81 years]. Causes of vitreous hemorrhage included trauma in 20 eyes [42.6%], diabetes mellitus in 9 eyes [19.1%], hypertension in 6 eyes [12.8%], following cataract surgery in 3 eyes [6.4%], following penetrating keratoplasty in one eye [2.1%] and unknown in 8 eyes [17.1%]. Visual acuity was counting fingers in 2 [4%], hand motion in 12 [27%] and light perception in 31 [69%] eyes. The diagnostic data of sonography were as follows: sensitivity 87.5%, specifity 64.5%, accuracy 72.4%, positive predictive value 56% and negative predictive value 90.9%. Ocular sonography is a useful diagnostic tool for evaluation of retinal detachment in patients with vitreous hemorrhage
