[Pilot study of transscleral light coagulation of retinal breaks using diode laser]
1Clinique Ophtalmologique Universitaire B, UFR Lyon-Nord, Hôpital de la Croix-Rousse.
Purpose:
We conducted a pilot trial to evaluate the efficacy and safety of transscleral diode laser photocoagulation in the management of retinal breaks.
Material And Methods:
Fourteen patients (14 eyes) were enrolled in the study. Twelve patients showed opaque media which prevented transpupillary argon laser photocoagulation (10 eyes) and/or a retinal detachment after previous failed surgery (3 eyes), and/or retinal tears with a curled and fixed posterior edge (6 eyes). Twenty five retinal breaks were treated in the 14 eyes (7 breaks in attached retina and 18 in detached retina).
Results:
A satisfactory retinochoroidal scar with permanent sealing of the retinal breaks was achieved in all eyes. The retina was attached in all eyes. The follow-up ranged from 2 to 12 months. Ten patients had a minimum 6 month-follow-up. Overtreatment attributed to technical mistake occurred in two eyes. It has no adverse effect on the final result.
Conclusion:
Transscleral diode laser photocoagulation of retinal breaks is efficacious and safe. It is a valuable alternative to cryo treatment in eyes at high risk of postoperative PVR and/or when argon laser photocoagulation cannot be used, and/or in retinal detachments after previous failed surgery.
