Purpose: To investigate the safety and efficacy of the use of navigated retinal laser as a delivery method of laser retinopexy in the treatment of symptomatic retinal tears.

Methods: We conducted a retrospective observational study of 69 patients presenting to a district general hospital in the United Kingdom with a diagnosis of symptomatic retinal tear who underwent retinopexy using a navigated retinal laser (Navilas 577s). Patients were followed up at two weeks or later to assess the efficacy and safety of the use of navigated retinal laser for retinopexy treatment.

Results: In total, 72 retinal tears in 69 patients were identified in our cohort. Of these cases, 70 (97.2%) retinal tears were treated with retinopexy using a navigated laser with a median treatment time 200 seconds. Two retinal tears could not be imaged on the navigated laser system and so underwent cryopexy. In 67/70 (95.7%) of retinal tears, one session of laser treatment using the navigated laser system was sufficient for primary management. The remaining three tears required a second session. No retinal tears treated with navigated laser treatment progressed to retinal detachment. There were no other complications seen with the use of this laser.

Conclusions: The use of navigated retinal laser as a method of laser retinopexy for the treatment of retinal tears shows comparable safety and efficacy with other studies using traditional retinal laser systems.
