Purpose: Chronic glaucoma after previous cataract surgery has several surgical options. The results of contact transscleral diode laser cyclophotocoagulation (CPC) for medically uncontrolled glaucoma in pseudophakic eyes were evaluated.
Method: At our clinic 20 eyes underwent CPC with subconjunctival anesthesia between 8/01 and 12/02. The burns were performed in 1.5 mm limbal distance sparing the temporal superior quadrant and existing filtering blebs (2000 mW, 2 sec, G probe, IRIS-medical Laser). Number of burns corresponded to preoperative maximal IOP under medical therapy. The IOP preoperatively, at discharge and at least 6 months postoperatively and the type of antiglaucomatous medical treatment was analyzed. The files were evaluated retrospectively.
Results: Mean age was 77 years. Before cataract surgery 7 eyes of 20 underwent antiglaucoma surgery (filtering surgery n=7, laser trabeculoplasty n=5, cyclcryocoagulaion n=3). For 3 eyes Re CPC within 4 months was necessary. For mean preoperative IOP of 30±8 mmHg 30±7 laser burns were applied. Follow up was 6-10 months. Postoperatively mean IOP was 17.3± 4.21 mmHg (p<0.05). Pre-and postoperatively medical treatment was 2 antiglaucomatous drugs. No complications were observed.
Conclusions: CPC reveales good IOP control for glaucoma in pseudophakia with the advantage of a technically simple procedure.
