PURPOSE The blue-sensitive pathway in normal subjects and in patients with primary open-angle glaucoma (POAG) was tested with the pattern visual evoked potential (VEP) method under selective adaptation. METHODS Recording of pattern-onset VEP in response to blue (460-nm) stripes (0.88 c/deg) presented either without or with a bright yellow (570-nm)(More)
PURPOSE To analyze techniques of measuring accommodation after implantation of an accommodating posterior chamber intraocular lens (PC IOL). SETTING Department of Ophthalmology and University Eye Hospital, University Erlangen-Nürnberg, Erlangen, Germany. METHODS This prospective study analyzed 23 eyes of 23 patients (aged 41 to 87 years) after cataract(More)
We used the laser flare-cell meter to measure aqueous flare and aqueous 'cells' in 38 eyes of 38 patients with pseudoexfoliation, in 36 normal control eyes of 36 subjects, and in 19 eyes of 19 patients with chronic open-angle glaucoma unrelated to pseudoexfoliation. In pseudoexfoliation eyes, both aqueous flare (0.61 +/- 0.55 mg/ml human albumin equivalent)(More)
Purpose. To analyze the incidence of and possible risk factors for endothelial corneal allograft rejection in a well-defined population following penetrating normal-risk keratoplasty. Methods. Since 1996 a longitudinal prospective study has been conducted to analyze the results of normal-risk penetrating keratoplasty. All patients underwent a standardized(More)
Melanoma incidence and mortality rates continue to increase despite the use of sunscreen as well as screening programs for early surgical excision of premalignant lesions. The steady increase in melanoma incidence suggests that additional preventive approaches are needed to augment these existing strategies. One unexplored area involves targeting genes(More)
Purpose. To assess the impact of diagnosis on corneal endothelial cell loss after nonmechanical penetrating keratoplasty (PK) with regression models. Methods. Five hundred eighty-nine eyes [273 with keratoconus (group I; PK only), 187 with Fuchs' endothelial dystrophy (group II; 77 PK only and 110 triple procedures) and 129 with bullous keratopathy (group(More)
PURPOSE Impairment of the blood-aqueous barrier in unoperated eyes with pseudoexfoliation syndrome has been demonstrated by fluorescein angiography, fluorophotometry, measurement of aqueous flare, and determination of aqueous protein. We performed noninvasive quantification of aqueous flare using the laser flare-cell meter to compare blood-aqueous barrier(More)
OBJECTIVE Aqueous melanin granules may be accurately quantified with the laser flare-cell meter and have been demonstrated to be increased in primary pigment dispersion syndrome (PDS). It was the aim of this study to correlate intraocular pressure, glaucomatous damage of the optic nerve head, and visual field defects with the number of aqueous melanin(More)
Background: The purpose of this study was to quantify breakdown of the blood-aqueous barrier (BAB) following penetrating keratoplasty (PK) with simultaneous extracapsular cataract extraction and posterior chamber lens implantation (triple procedure) and compare it with the alterations following PK only. Methods: This study included 72 eyes after triple(More)
PURPOSE The value of the ERG scotopic threshold response (STR), which is known to originate in the proximal retina and of the near-threshold scotopic PII(B-wave), was studied in glaucoma. METHODS Full-field single flashes were presented under scotopic conditions in two subject groups, a glaucoma group (n = 30) and a normal control group (n = 35). The(More)
