INTRODUCTION:Vitreoretinal pathologies include vitreal haemmorhage and vitreal detachment, retinal detachment, retinoblastoma, diabetic retinopathy, leukocoria, trauma over eye. The eye being an external sense organ lends itself to an easy and rapid examination of anterior segment but structure posterior to the papillary plane i.e lens, vitreous cavity and humor, retina, choroid in an opaque media could not be evaluated by just fundus examination. OBJECTIVES OF RESEARCH: Demographic prole of patient with vitreoretinal pathologies. Diagnose the patient with vitreoretinal pathologies by ultrasonography. Detect and characterize the vitreoretinal pathologies by ultrasonography, clinical ndings and post management conrmatory ndings to establish the diagnostic accuracy of ultrasonography in vitreoretinal pathologies. MATERIALAND METHOD: Study design:Institution based prospective, descriptive study Study setting: USG section at Dept. of Radiodiagnosis, Medical College, Kolkata Place of study: Dept. of Radiodiagnosis, Medical College, Kolkata Period of study:January 2018 to august 2019 Study population:Referred patient from regional institute of opthalmology Sample size: 50 patients. RESULT AND ANALYSIS: We showed that 29(48.3%0 patients had vitreous haemorrhage. 19(31.7%) patients had retinal detachment. 10(16.7%) patients had posterior vitreous detachment. 7(11.7%) patients had endophthalmitis. 9(15.0%) patients had retinoblastoma. 1(1.7%) patients had PHPV. 1(1.7%) patients had asteroid hyalosis. 1(1.7%) patients had retinoschisis. 5(8.3%) patients had normal. SUMMARYAND CONCLUSION: From, the present study it was noted that Ultrasonography is very efcient tool in diagnosing various ocular abnormalities. Ultrasonography can categorize the lesions in the posterior chamber well, depending on the echotexture and anatomy. Even the exact location of the lesion and surrounding structures can be well made out. Ultrasonography can detect structural changes that were missed or could not be detected by clinical examination especially with opaque media as well. Ultrasonography is proved to be very useful diagnostic tool in detection and evaluation of vitreo-retinal pathologies in patients with opacities in the vitreous cavity.
