Abstract
Purpose :
To evaluate the management of retinal tears and detachments using navigated laser (Navilas, OD-OS Inc., Berlin) depending on localization characteristics.
Methods :
Retrospective case series of patients with retinal tears and detachments managed with navigated laser. Patients were imaged with Navilas and Optos 200Tx (Optos, Dunfermline, United Kingdom) after navigated laser treatment. Images were analyzed for location, size and traction type.
Results :
Forty-one tears out of 37 eyes from 35 patients have been analyzed in this observational study. Mean age of all patients was 60 ± 11,5 (range 13-77) that had been treated with Navilas between January 2012 and November 2018 at Klinikum Augsburg, Germany.
All tears could be imaged and targeted with laser. Preliminary results show that 63% of tears and detachments have been located in the superior temporal area. Distance varied from 135 degrees up to 180 degrees from the macula. Mean number of laser spots was 869 ± 800 (range 56-3350), mean treatment power 401 ± 135 mW with mean pulse duration of 22 msec, and mean spot size of 269 ± 84 microns. Treatment failure only occurred in 1 case, where progression could not be haltered and vitrectomy had to be performed. Only 3 patients received an additional office based laser, 2 patients within 1 week. The number of laser spots was correlated to tear size and distance measured from the fovea.
Conclusions :
Navigated laser allows the treatment of all types of retinal tears and detachments onto the retina, even in the far periphery. Due to the treatment plan, laser spots are precisely locatable around the tear.
