Comparison of surgical outcome of trabeculectomy and phacotrabeculectomy in Chinese glaucoma patients

Our study retrospectively reviewed the surgical outcomes up to 3mo of 38 consecutive Chinese glaucoma patients who underwent trabeculectomy (n=18) or phacotrabeculectomy (n=20). Baseline age, visual acuity, and intraocular pressure were comparable. Intraocular pressure from post-operative 1d to 3mo were similar between 2 groups. Complete success was achieved in 65% of phacotrabeculectomy, and 66.7% of trabeculectomy cases; while failure occurred in 16.7% of phacotrabeculectomy, and 10% of trabeculectomy cases at 3mo. Phacotrabeculectomy group consistently showed better improvement in visual acuity. Diffuse blebs occurred in 65% of phacotrabeculectomy and 83% of trabeculectomy eyes; and flat blebs in 35% of phacotrabeculectomy, but none after trabeculectomy. There was more hypotony (5% vs 0) after phacotrabeculectomy. To conclude, phacotrabeculectomy and trabeculectomy demonstrated comparable intraocular pressure control up to 3mo post-operatively. However, phacotrabeculectomy patients had better visual acuity improvement. Nonetheless, more diffuse bleb and less hypotony were present following trabeculectomy

ExPRESS Mini-Shunt as a Treatment Alternative for Medically Uncontrolled Steroid-Induced Glaucoma in a Pediatric Patient

This case report illustrates the use of ExPRESS mini-shunt in a pediatric glaucoma patient. We describe the management of steroid-induced glaucoma with ExPRESS mini-shunt in a 9-year-old boy with allergic keratoconjunctivitis. The intraocular pressure of both of his eyes was uncontrolled with medical and laser treatment. Both eyes were treated with ExPRESS mini-shunt and mitomycin-C. Transient overfiltration with postoperative hypotony occurred in both eyes and resolved after 2 weeks. One year postoperatively, intraocular pressure was maintained below 21 mm Hg without medication in 1 eye. Bleb needling with mitomycin-C was done to maintain filtration. The fellow eye received cataract extraction but developed bleb failure a few months afterwards. The intraocular pressure was controlled medically. To conclude, ExPRESS mini-shunt is a new surgical option in selected patients. Bleb failure developed after cataract extraction. Postoperative inflammation should be minimized. Patient selection, such as those with stable ocular condition, is important to increase surgical success
