Abdelrahman, A. M., "Noninvasive glaucoma procedures: current options and future innovations.", Middle East African journal of ophthalmology, vol. 22, issue 1, pp. 2-9, 2015 Jan-Mar. Abstract

Noninvasive glaucoma procedures (NIGPs) represent a new dawn in the management of glaucoma. They try to fill the gap between the shortcoming of invasive glaucoma surgeries and antiglaucoma medications. NIGPs were introduced as an adjunct or alternative treatments for glaucoma. Some of these procedures have shown good efficacy with few serious complications. Hence, they are now used as both primary and adjunctive therapy for glaucoma. The most common NIGPS involve laser and ultrasound technologies. Currently, the portfolio of NIGPs includes argon laser trabeculoplasty, selective laser trabeculoplasty, and micropulse diode laser trabeculoplasty. More recent innovations include therapeutic ultrasound for glaucoma, ultrasonic circular cyclocoagulation, and deep wave trabeculoplasty.

Abdelrahman, A. M., and R. M. Eltanamly, "Selective laser trabeculoplasty in Egyptian patients with primary open-angle glaucoma.", Middle East African journal of ophthalmology, vol. 19, issue 3, pp. 299-303, 2012 Jul-Sep. Abstract

PURPOSE: To assess the change in intraocular pressure (IOP) in Egyptian patients after selective laser trabeculoplasty (SLT) as a primary or adjunctive treatment for primary open-angle glaucoma (POAG).

MATERIALS AND METHODS: One hundred and six eyes with POAG were enrolled in this prospective study. Patients were divided into two groups: recently diagnosed cases with no preoperative medications (group 1) and; patients with confirmed glaucoma on medical therapy (group 2). All patients underwent 360° SLT. Patients were evaluated to 18 months postoperatively. Data were analyzed on postoperative changes in IOP, number of medications and complications. A P-value less than 0.05 was statistically significant.

RESULTS: A statistically significant drop in IOP occurred, from 19.55 ± 4.8 mmHg preoperatively, to 16.03 ± 2.8 mmHg postoperatively (P < 0.001). Each group had a statistically significant drop in IOP (P < 0.001). There was a statistically significant decrease in the number of medications in group 2 from 2.25 ± 0.97 medications preoperatively to 1.0 ± 1.3 medications postoperatively (P = 0.004). No serious complications occurred for the duration of the study.

CONCLUSION: SLT can be safely and effectively used as primary or adjunctive therapy for the treatment of POAG.

Elnaby, E. A., O. M. El Zawahry, A. M. Abdelrahman, and H. E. Ibrahim, "Phaco Prechop versus Divide and Conquer Phacoemulsification: A Prospective Comparative Interventional Study.", Middle East African journal of ophthalmology, vol. 15, issue 3, pp. 123-7, 2008 Jul. Abstract

PURPOSE: To compare two phaco techniques, namely Phaco Prechop and Divide and conquer, basically during their early learning curves.

PATIENTS AND METHODS: The study included 50 patients divided into 2 groups, each including 25 patients; group (A) where phaco Prechop was performed, and group (B) in which divide and conquer was performed. The mean effective ultrasound time, mean endothelial cell count, mean endothelial cell loss, corneal thickness, intraoperative complications, and the best corrected visual acuity were reported in the two groups both preoperative and postoperative.

RESULTS: The mean effective ultrasound time in group A was 19.36 ± 8.51 seconds, and in group B, it was 24.44 ± 7.86 seconds with a statistically significant difference between the two groups (P = 0.033). The mean endothelial cell count 3 months postoperative in group A was 2139.88 cells/mm(2). In group B, the mean endothelial cell count 3 months postoperative was 2087.08 cells/mm(2). The difference between the two groups was statistically insignificant (P = 0.558), however The difference in endothelial cell loss 3 months postoperatively between the two groups was statistically significant. (P = 0.001). Four cases in groups A (16%) had posterior capsular rents compared to three cases (12 %) in group B. Postoperative best corrected visual acuity in group B was 6/12 or better in 88% of cases as compared to 92% in group A with no statistical difference.

CONCLUSION: Early cataract surgical cases performed with the Phaco Prechop and divide and conquer techniques showed comparable results and complications. However the former technique utilized less phaco time and energy without significant effect on the final surgical outcome.

Abdelrahman, A. M., "Trabeculotome-guided deep sclerectomy. A pilot Study.", American journal of ophthalmology, vol. 140, issue 1, pp. 152-4, 2005 Jul. Abstract

PURPOSE: To describe and evaluate a new technique that helps identification and unroofing of Schlemm's canal during deep sclerectomy.

DESIGN: A prospective, interventional case series.

METHODS: This pilot study was conducted on 15 eyes with various types of glaucoma. After dissecting the superficial scleral flap, the trabeculotome was inserted inside the Schlemm's canal. During deep flap dissection, a direct incision was made over the trabeculotomy to open and unroof Schlemm's canal. Five of the excised deep flaps were submitted for histologic examination.

RESULTS: In 13 of the 15 eyes, the Schlemm's canal was properly identified and unroofed. Schlemm's canal endothelium was identified in all the examined specimens. The mean intraocular pressure was reduced from 26.66 +/- 4.54 mm Hg to 12.2 +/- 3.5 mm Hg at the end of a mean follow-up of 9.4 +/- 2.9 months.

CONCLUSION: The insertion of the trabeculotome inside Schlemm's canal before dissection of the deep flap helped Schlemm's canal unroofing.
