Purpose: To determine the flow characteristics of the 3 different models of the Ex-PRESS miniature glaucoma device in a controlled laboratory study.
Materials And Methods: The 3 different Ex-PRESS models (P-50, R-50, and P-200; Optonol Ltd; now Alcon Lab) were tested using a gravity-driven flow test. Three samples of each of the 3 Ex-PRESS models were subjected to a constant gravitational force of fluid at 5 different pressure levels (5 to 25 mm Hg).
Novel technique for Nd:YAG posterior capsulotomy in pediatric patients.
J Pediatr Ophthalmol Strabismus

A 7-year-old girl had posterior capsule opacification 2 years after cataract extraction without posterior capsulotomy. This report describes a novel technique for Nd:YAG posterior capsulotomy in pediatric patients for providers who do not have access to an overhead-mounted Nd:YAG laser.

Methods: The intercellular junctions in SCEs were made visible by transfection of a plasmid containing a GFP-tagged gene for ZO-1 protein. Transfected SCEs were treated with media conditioned by lasered trabecular meshwork endothelial cells (TMEs), or with latanoprost, bimatoprost, or travoprost.
Purpose: To determine whether 25-gauge transconjunctival sutureless vitrectomy incisions are more likely to allow the inflow of ocular surface fluid than sutured vitrectomy incisions.
Methods: Four groups of cadaver eyes underwent three-port vitrectomy in a laboratory setup. Groups A and B had 25-gauge vitrectomy, with and without conjunctival displacement, respectively, and were left unsutured.
