SITA STANDARD AS A SCREENING TOOL IN GLAUCOMA EVALUATION- A PROSPECTIVE STUDY TO DETERMINE ITS SPECIFICITY AND SENSITIVITY
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2018, Vol 5, Issue 17
Abstract
BACKGROUND Characteristic visual field defects are the primary criteria to diagnose glaucoma and to monitor its progression. With the increased awareness about this disease and inclusion of glaucoma evaluation in the routine clinical examination of all patients above 40 years of age, there is a need for faster screening algorithm with good reliability, reproducibility, specificity, and sensitivity. The aim of this study was to determine the sensitivity and specificity of SITA Standard protocol and evaluate its use as a screening tool for POAG. MATERIALS AND METHODS A 1-year prospective study conducted in the Glaucoma clinic of a tertiary care hospital in Northern Karnataka, where all newly diagnosed cases underwent sequential automated perimetry with a full threshold and SITA Standard algorithm. Eye with a more severe defect was considered for analysis. RESULTS 60 eyes of 60 patients were enrolled. Mean age of presentation was found to be 63.63 years. The sensitivity of SITA Standard was found to be 95.24% while specificity was found to be 94.44%. The test time was reduced by 45.84% when compared to Full Threshold Algorithm. CONCLUSION SITA Standard reduces the test time by almost half with reliable results and thus provides a good option to be used as a screening test in glaucoma clinics.
