Reliability of Ocular Ultrasonography Findings for Pre-surgical Evaluation in Various Vitreo-retinal Disorders

Abstract

Objective: To find the reliability of ocular ultrasonography (USG) for pre-surgical evaluation in various vitreo-retinal conditions. Method: In a retrospective study, a chart review of patients who underwent preoperative USG for various vitreoretinal conditions was done. We correlated findings of preoperative USG with intraoperative findings. Results: 131 of 130 patients were included. Various ocular pathologies included trauma, diabetic vitreous hemorrhage, endophthalmitis, and other causes of vitreous hemorrhage. We found overall sensitivity and specificity of 92.31% and 98.31% for identification of rhegmatogenous retinal detachment, and 96.2% and 100% for posterior vitreous detachment, respectively, whereas it was 100% for vitreous hemorrhage, preretinal bleed, and vitreous exudates. In eyes with trauma, sensitivity and specificity of USG for identifying the status of retina was least (90.9% and 97.7%). Conclusion: Our study highlighted that the reliability of USG findings was least in cases of trauma, hence requiring special care while reporting.
