A 54-year-old woman with an epiretinal membrane in her left eye accompanied by a shallow anterior chamber due to primary angle closure glaucoma underwent vitrectomy and cataract surgery. During the cataract surgery, immediately after the ultrasonic tip had been removed from the anterior chamber, anterior chamber flattening occurred. An intraoperative fundus examination showed the development of...

Purpose. To quantify changes in anterior segment (AS) parameters after laser peripheral iridotomy (LPI) using AS-optical coherence tomography (OCT) of iris bombe. Method. AS images of eight eyes were captured before and after iris bombe and more than 2 weeks after LPI (post-LPI) using AS-OCT. We compared the following AS parameters: anterior chamber depth (ACD), anterior chamber volume (ACV), i...

Background: It has been estimated that 67 million people worldwide are affected with a primary glaucoma and that one-third have primary angle closure glaucoma. We aimed to determine the biometric differences between the eyes of patients with acute attack of primary angle closure and their non-involved fellow eyes. Methods: Twenty eight patients with acute attack of primary angle closure were re...

PURPOSE To compare the measurement of anterior chamber depth exclusive of corneal thickness using Orbscan IIz and ultrasound biomicroscopy (UBM) and evaluate the repeatability of each method. METHODS Three consecutive measurements of anterior chamber depth were prospectively performed using Orbscan IIz and Paradigm 50-MHz UBM in 40 eyes in 20 individuals. Mean values were compared using the p...

PURPOSE Vitrectomy, when followed by cataract surgery, increases the risk of open-angle glaucoma. This study was conducted in patients to determine whether these procedures are associated with increased exposure of the trabecular meshwork to oxygen. METHODS Oxygen distribution was recorded with a fiberoptic probe in patients undergoing surgery for cataract, glaucoma, or retinal disease. pO(2)...

PURPOSE To investigate changes in anterior chamber depth (ACD), corneal volume (CV), anterior chamber angle (ACA), anterior chamber volume (ACV), central corneal thickness (CCT), horizontal visible iris diameter (HVID), pupil diameter (PD), and intraocular pressure (IOP) after uneventful phacoemulsification cataract surgery with intraocular lens implantation. METHODS A total of 132 eyes of 13...

The influence of acute coronary occlusion on systolic and diastolic left ventricular pressure-volume relations was studied in 10 patients undergoing percutaneous transluminal coronary angioplasty (PTCA). Pressure-volume relations were obtained by conductance catheter and micromanometer techniques and with volume load altered by transient inferior vena caval occlusion. End-systolic and end-diast...

Ocular involvement with Gnathostoma spinigerum occurs years after the initial infection that is acquired by ingestion of poorly cooked, pickled seafood or water contaminated with third stage larvae. Here we report a case of gnathostomiasis of the left eye of a 32-year-old lady hailing from Meghalaya, India. Her vision had deteriorated to hand movement. Slit lamp examination revealed a live, act...

The anterior chambers of 27 rabbit eyes were perfused at constant pressure with room temperature (25 degrees C) or cooled (11 degrees C) balanced salt solution at constant flow rates of 4.8 ml/min or 8.5 ml/min. Intraocular temperature changes in the anterior chamber, anterior vitreous, mid vitreous, and posterior vitreous and on the retina surface were monitored with an intraocular thermocoupl...
