Methods: In this randomized, prospective, double masked study, we examined the effects of single, 300 mg. oral administration of caffeine in healty volunteers by using color Doppler imaging to measure retrobulbar vessels hemodynamics. Results: Neither blood pressure nor in-展开更多
Purpose: To correlate structural parameters of the optic nerve head and global indices of short-wavelength automated perimetry (SWAP) in ocular hypertensives. Methods: The study included 195 eyes with ocular hypertens...Purpose: To correlate structural parameters of the optic nerve head and global indices of short-wavelength automated perimetry (SWAP) in ocular hypertensives. Methods: The study included 195 eyes with ocular hypertension (IOP>21 mmHg, normal conventional automated perimetry). Short-wavelength automated perimetry was performed (full-threshold, 24-2). The optic展开更多
Purpose: Electronmicroscopic characteristics of anterior lens capsule and cortical fiber cells from glaucomatous patients who underwent combined trabeculectomy and phacoemulsification were compared with capsule specim...Purpose: Electronmicroscopic characteristics of anterior lens capsule and cortical fiber cells from glaucomatous patients who underwent combined trabeculectomy and phacoemulsification were compared with capsule specimens and cortex from catarac-tous lenses of non-glaucomatous patients. Methods: A phacotra-beculectomy or phacoemulsification were performed in 26 glaucomatous eye (Group 1).展开更多
