Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 2
Abstract
Purpose: For evaluation of preoperative posterior segment with B Scan to detect pathologies that may influence the surgical strategy and postoperative visual prognosis. Introduction: Eye is affected by spectrum of pathological conditions occurring in all age groups from new born to old age. Ultrasound is a safe non-invasive procedure which can be performed in the outpatient department without any sedation and radiation exposure. Ultrasonography has greatly advanced enabling us in studying the posterior segment of the eyes which cannot be viewed in the presence of opaque media. B-scan is a useful tool for the assessment of many ocular and orbital diseases. It provides us with adequate information which is not derived from clinical examination alone. Diagnostic ophthalmic ultrasonography is the first line of investigation in suspected Vitreo retinal diseases with opaque media. B-scan ultrasound is most useful when direct visualization of intraocular structures is difficult or impossible and also indicated in presence of clear ocular media for evaluation and differentiation of intra ocular tumors, ocular inflammatory diseases. Method:A prospective observational study of patients with suspected posterior segment pathology having an opaque ocular media. Result: Total 100 patients studied: 44 operated for cataract surgery and 56 for posterior segment surgery. Preoperative USG findings were matched accurately in 28/44 (63.63%) cataract surgery patients, whereas, this accuracy was noted in 38/56 (67.85%) of patients with posterior segment pathology. Conclusion: Preoperative ocular USG is important & supportive before plan of ocular surgery as well as to give prognosis, but it is not 100% accurate in all the cases everytime.
