Purpose: Flicker perimeter is composed in Octopus automated perimeter to measure critical fusion frequency (CFF) in the visual field of central 30 degrees. It can evaluate Magnocellular pathway and is expected for early diagnosis of glaucoma. We performed flicker perimetry and automated static perimetry to evaluate recovery of retinal function in patient with rhegmatogenous retinal detachment (RRD) with macula detachment after scleral buckling. Methods: Three eyes from 2 males and 1 female patients were included in this study. Case1 is a 40-year-old female, case2 is a 58-year-old male, and case3 is a 62-year-old male. Automated static perimetry (Humphrey Field Analyzer, program C30-2) and flicker perimetry (Octopus301, G1 program with tendency oriented perimetry) were measured after surgery. We compared mean sensitivity of HFA with mean CFF of flicker perimetry in the area of detached retina. Results: Mean sensitivity of HFA in the area of detached retina was 17.5dB(1 Post Operative Day, POD), 17.4dB(4POD), 17.5dB(11POD), 19.1dB(27POD), mean CFF in the area of detached retina was 29.7Hz, 35.5Hz, 34.7Hz, 35.6Hz in case1. Mean sensitivity of HFA was 14.6dB(1POD), 19.6dB(11POD), 20.4dB (18POD), mean CFF was 15.7Hz, 24.1Hz, 23.1Hz in case2. Mean sensitivity of HFA was 19.8dB(1POD), 24.6dB(7POD), 23.3dB(14POD), mean CFF was 17.7Hz, 24.5Hz, 25.5Hz in case3. Conclusions: Mean CFF of flicker perimetry in the area of detached retina tend to recover earlier than mean sensitivity of HFA. Magnocellular pathway might recover earlier in detached retina after RRD surgery. CR: N
