title: 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.
  
  
  METHODS
  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%).
  
  
  CONCLUSIONS
  Our study highlighted that the reliability of USG findings was least in cases of trauma, hence requiring special care while reporting.
