Scleral Perforation following Transscleral Diode Laser Cycloablation:

Transscleral Diode laser cycloablation (DLCA) is one of the cycloablative procedures usually used for treating cases of refractory glaucoma. We report here a case of 80 years old man, who underwent transscleral diode laser cycloablation in his left painful blind eye. The main aim of this treatment was to lower down the intraocular pressure so that his pain could be relieved. On regular follow up visit, just two weeks after the procedure, he presented with scleral perforation on inferior 180 degrees of eye exactly where laser was applied. His intraocular pressure was 12mmHg. Patient had to undergo tectonic and conjunctival grafting on emergency basis to save the integrity of the globe and to avoid phthisis, pain and infection. His post op intraocular pressure (IOP) was 10mmHg with graft in place. This is a very rare complication and to the authors knowledge, this is first reported case of scleral perforation following transscleral diode laser cycloablation in Pakistan
