Intraocular Pressure Following Phacoemulsification and Endoscopic Cyclophotocoagulation for Advanced Glaucoma: 1-Year Outcomes.

PURPOSE: To evaluate changes in intraocular pressure (IOP), vision, and medications at least 1 year after phacoemulsification combined with endocyclophotocoagulation for advanced glaucoma and cataract. METHODS: A retrospective chart review was conducted on patients with advanced glaucoma who underwent phacoemulsification combined with endocyclophotocoagulation at King Khaled Eye Specialist Hospital between 2005 and 2012. Data were collected on patient demographics, type of glaucoma, IOP over time, best-corrected visual acuity, number of glaucoma medications, comorbidities, and previous surgeries. Absolute success was defined as IOP≤15 mm Hg without medication and qualified success was IOP≤15 mm Hg with medications. Statistical significance was indicated by P<0.05. RESULTS: The study sample comprised 104 eyes (104 patients). Mean follow-up was 17.3±1.8 months. Mean IOP decreased from 17±1.4 mm Hg preoperatively to 14.7±1.3 mm Hg at the last postoperative visit. Absolute success was achieved in 11.9% (95% confidence interval, 5.6-18.2) of the eyes. Qualified success was achieved in 72.3% (95% confidence interval, 63.5-81.0) of the eyes. Best-corrected visual acuity improved by ≥2 lines in 76 (73%) eyes. Eyes with primary open-angle glaucoma had the higher absolute and qualified success rates compared with primary angle-closure and pseudoexfoliation glaucoma (P>0.05). Only 48 (46%) patients required >3 medications for IOP control compared with 78 (75%) patients before surgery. CONCLUSIONS: At ≥1 year postoperatively, the absolute success rate of treating advanced glaucoma by endocyclophotocoagulation and phacoemulsification was low. However, medication burden was reduced. Owing to the significant variation in the success rate based on the type of glaucoma, patients with advanced glaucoma should be carefully selected and counseled.

Current surgical options for the management of pediatric glaucoma.

Currently, there are numerous choices for the treatment of pediatric glaucoma depending on the type of glaucoma, the age of the patient, and other particularities of the condition discussed in this review. Traditionally, goniotomy and trabeculotomy ab externo have been the preferred choices of treatment for congenital glaucoma, and a variety of adult procedures adapted to children have been utilized for other types of pediatric glaucoma with variable results and complications. More recently, seton implantations of different types have become more popular to use in children, and newer techniques have become available including visualized cannulation and opening of Schlemm's canal, deep sclerectomy, trabectome, and milder more directed cyclodestructive procedures such as endolaser and transcleral diode laser cyclophotocoagulation. This paper reviews the different surgical techniques currently available, their indications, results, and most common complications to allow the surgeon treating these conditions to make a more informed choice in each particular case. Although the outcome of surgical treatment in pediatric glaucoma has improved significantly, its treatment remains challenging.
