Summary

Purpose: To investigate the effects of subliminal micropulse yellow laser application on central macular thickness and best corrected visual acuity in cystoid macular edema secondary to retinitis pigmentosa patients.

Interventions

DEVICE

SL-MPL treatment protocol was performed with a 577 nm yellow laser (EasyRet, Quantel Medical, Cedex, France)

Macular laser treatment was applied after pupil dilation and topical anesthesia. Laser application was performed with a Mainster Standard contact laser lens (Volk Optical, Mentor, OH, USA). To determine the appropriate personalized calibration value, single-spot test shot was applied under the green filter to a non-edematous area of the macula outside the temporal vascular arcade. The laser power was gradually increased until it formed a barely visible laser spot. The power of the micropulse pattern laser was set at 50% of the power needed to form a barely visible laser spot. Laser parameters used were 200 ms duration, 160 µm spot diameter, low operating cycle (5%), and zero spacing with 5x5 pattern shape. SL-MPL was applied to the areas where edema was detected in OCT and examination.
