REST AN INNOVATIVE RAPID EYE SCREENING TEST

Abstract

Results: Mean visual acuity using ETDRS was 0.086 9 0.194 for right eye (RE) and 0.085 9 0.196 for left eye (LE) while REST measurement was 0.091 9 0.182 for RE and 0.098 9 0.203 for LE. There was significant and strong direct correlation between visual acuity using ETDRS and REST in both eyes (RE: r 0.829; p B 0.001, LE: r 0.871; p B 0.001). The 95% limits of agreement between the two charts was 90.11 LogMAR for right eye and 90.10 LogMAR for left eye. Time taken for REST was significantly shorter than ETDRS (p B 0.001). Conclusion: REST is accurate and time-saving, thus potentially ideal for mass screening in remote area.
