New method of lasercoagulation in treatment of retinoschisis

Abstract

Abstract Purpose Retinoschisis is a minimum retinal splitting of retina which is seen in ophthalmoscopy. Methods Laser treatment was conducted on 60 eyes. 30 eyes were with 2nd stage of process, 20 with 3rd stage. Diode laser “Milon Lachta” was used. Radiation parameters were as follows: wave‐length – 0,83 mkm, radiation power 350‐850 mWt, exposition 0.2 s, diameter of spot pointing was 150‐200 mkm. In 5 days we carried out our method of staged advancing laser coagulation beginning from retinal macular zone along all cyst area and along vessels. As intraretinal fluid was diminishing we moved to periphery till full blockage of limited area of retinoschisis or complete intraretinal fluid resorption. As criteria of positive laser action we considered cyst flattening and visible in ophthalmoscopy intraretinal fluid resorption with the appearance of distinct border between retina without fluid and retinoschisis with coagulant pigmentation. Results Success is connected with technical biologic peculiarities of diode laser action on retinaand choroid and with method of laser coagulation application. Conclusion Success is connected with technical biologic peculiarities of diode laser action on retinaand choroid and with method of laser coagulation application.
