Role of B-Scan Ultrasonography in Evaluating Posterior Segment of the Eye in the Event of Non Visualization of Fundus
Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 7
Abstract
Background: Evaluation of posterior segment of eye in hazy ocular media is difficult ophthalmoscopically. B-scan ultrasonography is an important tool in such cases. Purpose: To evaluate the status of the posterior segment of eyes in patients with opaque ocular media due to any reason. Materials and Methods: This prospective study was conducted in the Ophthalmology department of a tertiary care hospital over a period of one year from November 2015 to October 2016, on two hundred patients presenting with opaque ocular media. After detailed history and clinical examination, B-scan ocular examination was done using ultrasound machine - Nidek US-4000 (Echoscan) with the contact method. Data was entered in Microsoft excel and Chi Square test was used for statistical analysis. Results: Out of 200 patients, 141 (70.5%) were males and 59 (29.5%) -females. The patients had an age range between 6 months to 90 years. The mean age was 47.845 ± 22.95 years. Majority of patients (34%) were in the age group ≥61 years. The most common indication of ocular sonography in our study was opaque media due to lenticular opacity (48.5%). One hundred eight patients (54%) did not demonstrate any posterior segment pathology on B-scan echography. Two most common posterior segment lesions found in our study were vitreous haemorrhage (VH) - 18.50% and retinal detachment (RD) combined with vitreous disorders- 8%, respectively. Other B-scan findings were isolated retinal detachment group which comprised 7%, retinoblastoma - 1.5% patients, total choroidal detachment (1.5%), endophthalmitis (1%), dislocated PCIOL in vitreous (1%) and phthisis bulbi -0.5%. Conclusion: B scan ultrasonography is an indispensible tool in examination of posterior segment in patients with opaque ocular media, where a preoperative fundoscopic evaluation is virtually impossible.
