Aims: To compare the decision to treat between the practitioner and Star and Star II calculator for ocular hypertension patients. Study Design: A comparative cross sectional retrospective analytical study. Method: A retrospective analytical study, conducted at Glaucoma clinic of Dr. R M L hospital. All files of diagnosed cases of ocular hypertension were considered for the study. Information was gathered for each of the following 6 risk factors- Age, Sex, Intra-Ocular pressure, Vertical Cup-Disc ratio, Pattern Standard Deviation (PSD), Central Corneal Thickness (CCT). Results were compared with the clinical decision for treatment taken by glaucoma practitioners well versed with OHTS and EGPS guidelines for treatment of OHT and having more than ten years of experience in their field. Result: Records of a total of 1780 files registered in the glaucoma clinic of the hospital were screened. 202 files were cases of OHT. After applying the strict STAR II inclusion criteria only 32 patient files were selected for the study. These results were subjected to statistical analysis using Mcnemar test which revealed that there was no statistical difference between the two (p = 0.3018) at 95% confidence interval. Conclusion: Our study found no statistically significant difference between the decision to treat by the two modalities i.e. STAR II (using 15% cut-off) and the clinician decision. STAR calculator can be of help in management of a case of OHT.
