OBJECTIVES This study quantified serially biventricular emptying and filling after infarction and related these to changes in volume, muscle mass, wall stress and contractility. BACKGROUND There are limited data on serial changes in ventricular dynamics after infarction. METHODS Forty patients had serial electron beam computed tomographic examinations during the first year after index Q wav...

The original technique of staining the anterior capsule of the lens with Trypan blue involves the injection of an air bubble in the anterior chamber. A drawback of this technique is the possible instability of the anterior chamber caused by the sudden exit of air when the dye is injected with the cannula through the side-port incision. Other staining techniques that use viscoelastic substances ...

Many teleosts use gas-filled swimbladders to control buoyancy and influence three-dimensional orientation (pitch and roll). However, swimbladder volume, and its contributions to these functions, varies with depth-related pressure according to Boyle's law. Moreover, the swimbladder volume at a given depth also depends on the compliance of the swimbladder wall, but this latter factor has been inv...

AIMS The tonographic effect is a phenomenon of intraocular pressure (IOP) reduction following repeated tonometry. This study examines whether the tonographic effect occurs following IOP measurement performed with Ocular Response Analyzer (ORA). METHODS Both eyes of 31 glaucoma patients and 35 healthy controls underwent nine IOP-measurements performed with GAT and ORA. The number of GAT and OR...

PURPOSE To compare the ocular anterior chamber depth, white-to-white distance, anterior chamber angle, and pupil diameter, as measured with two different Scheimpflug imaging devices. METHODS This transversal study included 80 right eyes from 80 subjects aged from 20 to 40 years. Their spherical equivalents ranged from -4.25 to +1.00 diopters (D). Each eye's anterior chamber depth, white-to-wh...

PURPOSE To determine the effect of bumetanide inhibition of Na-K-Cl cotransport on aqueous humor formation and outflow facility in living cynomolgus monkeys, outflow facility in organ-cultured human eyes, and contraction in bovine ciliary muscle and trabecular meshwork strips, in vitro. METHODS Aqueous humor formation in monkeys was measured fluorophotometrically for 6 hours, 1 to 6 weeks bef...

PURPOSE To compare the keratometric and pachymetric parameters of healthy eyes with those affected by steep cornea and keratoconus (KC) using Scheimpflug camera. SETTING Briz-L Eye Clinic, Baku, Azerbaijan. DESIGN A cross-sectional study. METHODS In this study, 49 KC (Amsler-Krumeich stage 1) eyes and 36 healthy eyes were enrolled. A complete ophthalmic evaluation and a Scheimpflug camera...
