Primary Transscleral Diode Laser Cyclophotocoagulation for Management of Glaucoma in Nanophthalmic Eyes

Purpose:The aim of this study was to assess the efficacy and safety of double-row transscleral cyclophotocoagulation in controlling intraocular pressure in patients with secondary angle closure glaucoma due to nanophthalmos, not being controlled by medical therapy. Patients and Methods:A prospective case series study that included 13 eyes of 8 patients diagnosed with secondary angle closure glaucoma due to nanophthalmos at the Giza Eye Subspeciality Center, treated by 24 cyclodiode applications in a double-row technique. Success was defined as complete success by control of intraocular pressure <21 mm Hg without medication and qualified success in which control of pressure <21 mm Hg achieved with 1 or 2 medications. Results:The average reduction in intraocular pressure at 3 months was 57.3 +/- 20.14% and at 6 months 44.5 +/- 32%, with an average eye drop intake of 1.3 +/- 0.8 drops. There was a significant reduction of intraocular pressure at 6 months compared with the preprocedure pressure (P=0.01). Complete success achieved in 3 eyes, pressure controlled without any medication, and qualified success in 9 eyes. Conclusion:Transscleral cyclophotocoagulation is a safe and effective primary therapy for managing glaucoma in nanophthalmic eyes.
