Combined extracapsular cataract extraction with ahmed glaucoma valve implantation in phacomorphic glaucoma.

PURPOSE: To report a retrospective analysis of a combined procedure of extracapsular cataract extraction (ECCE) with heparin surface modified (HSM) posterior chamber intraocular lens (PCIOL) implantation along with primary Ahmed glaucoma valve (AGV) implantation in an attempt to optimize visual acuity gains and intraocular pressure (IOP) control in patients with phacomorphic glaucoma. METHODS: ECCE with HSM PC IOL and AGV implantation was performed through two separate incisions in 15 patients diagnosed with phacomorphic glaucoma. Postoperative improvement in visual acuity and IOP control were monitored. RESULTS: A steady control of IOP was maintained in all patients with minimum anti-glaucoma medications. The average visual acuity was approximately 6/24 at 3 months. CONCLUSION: Superior preoperative IOP control and a shorter phacomorphic attack resulted in better postoperative vision. The successful maintenance of IOP within the desired range in this study suggests that the procedure should be performed under similar conditions.

Effect of levodopa and carbidopa in human amblyopia.

BACKGROUND: To assess the role of continuous therapy for 3 weeks with levodopa and carbidopa in the management of human amblyopia in children and adults. METHOD: There were 88 amblyopic eyes of 82 subjects included in this double masked randomized prospective clinical trial. Levodopa and carbidopa combination in 2 different dosage schedules were given to both adults and children. The response was monitored of the improvement in visual acuity, contrast sensitivity, and visually evoked potentials. RESULT: Patients receiving higher dosages of levodopa and carbidopa in both adults and children showed a better response to treatment. However, the effect did not last beyond 9 weeks of stopping treatment. CONCLUSION: Though levodopa and carbidopa therapy may not be able to ameliorate amblyopia on its own on a long-term basis, it may be considered nonetheless to be an important adjunct to conventional therapy because it may improve patient compliance for occlusion by improving visual acuity in the amblyopic eye. Thus, it offers promise of improving the functional outcome in these cases. However, longer follow-up trials are needed to substantiate these conclusions.

A comparative study of small incision trabeculectomy avoiding tenon's capsule with conventional trabeculectomy.

BACKGROUND AND OBJECTIVE: The purpose of this study was to compare the results of small incision trabeculectomy (SIT) avoiding Tenon's capsule vis-à-vis conventional trabeculectomy, and find a safe, effective alternative to conventional trabeculectomy with or without pharmacological wound modulation. PATIENTS AND METHODS: A controlled prospective study was conducted on 80 consecutive open-angle glaucoma patients requiring glaucoma filtration surgery. They were divided into two groups: Group I (n = 40): patients undergoing conventional trabeculectomy; and Group II (n = 40): patients undergoing limbal approach SIT. Patients were followed up serially for a minimum of 12 months and their intraocular pressure was monitored. Success of the procedure was defined as an intraocular pressure (IOP) <22 mm Hg with no additional antiglaucoma medication or surgery, and achieving at least a 30% reduction from the initial IOP at which optic disc cupping and/or visual field changes occurred. RESULTS: A significant fall (P <0.0001) in the final mean IOP was present in both groups at all time intervals in comparison to their preoperative values. The final mean intraocular pressure achieved with conventional trabeculectomy was 18.90 +/- 4.86 mm Hg versus 16.60 +/- 5.93 mm Hg with SIT. The final success rate of 90% was obtained with SIT vs 80% with conventional trabeculectomy. No major complications were encountered with either procedure although complications such as shallow anterior chamber and progression of cataractogenesis were seen more often in patients undergoing conventional trabeculectomy. CONCLUSION: Small incision trabeculectomy avoiding Tenon's capsule is a low-cost and safe alternative to conventional trabeculectomy that effectively reduces IOP in 90% of cases. The use of a small 2.5 mm limbal incision, which obviates the dissection of Tenon's capsule and absence of any major complication, suggests that this procedure be used more often in glaucomatous eyes needing filtering surgery.

Electrical cataract: a case study.

A case of bilateral cataract sustained after electrical trauma was seen in a referral practice. We examined a young patient with dense anterior and posterior subcapsular cataract in his right eye and pseudophakia in his left eye who gave a history of gradually progressive painless loss of vision after sustaining injury from a high voltage electric current. Extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens (PCIOL) implantation was performed in his right eye. Visual rehabilitation in both eyes after ECCE with PCIOL implantation was good with the patient attaining uncorrected visual acuity of 20/30 in both eyes postoperatively. It appears that the surgical results and visual rehabilitation after ECCE with PCIOL implantation in patients with electrical cataract without any other ocular damage is excellent.
