In the search for more accurate ways to determine intraocular pressure, the Halberg applanation tonometer may represent an alternative to the Schi0tz tonometer for routine screening pressure measurements. Although between 100 to 150 measurements are generally required to gain proficiency with the Halberg, the instrument is accurate in patients with normal corneas even with very abnormal scleral...
PURPOSE To report in vivo confocal microscopic (IVCM) features in corneal edema supported by histopathologic correlation. METHODS This was an observational study with evaluation of diagnostic technology. Twenty patients with clinically diagnosed corneal edema were involved, including 11 with Fuchs' endothelial dystrophy (FED). All cases, in addition to a control group of six normal eyes, were...
OBJECTIVE To determine whether graft survival over a 5-year follow-up period using corneal tissue from donors older than 65 is similar to graft survival using corneas from younger donors. DESIGN Multicenter prospective, double-masked, controlled clinical trial. PARTICIPANTS One thousand ninety subjects undergoing corneal transplantation for a moderate-risk condition (principally Fuchs' dyst...
Corneal thickness changes were monitored in ten subjects (1) over a 36-hour period without contact lens wear and (2) during 7 days continuous wear of three types of hydrogel contact lenses of different back vertex powers. Measured on awakening, the mean overnight central corneal edema without lenses was 3.0% ± 1.2%. With the lenses used in this study, the mean overnight corneal swelling over th...
PURPOSE We report the case of a 77-year-old man with no history of keratoconus or other ectatic disorders who presented with corneal hydrops in the setting of a corneal ulcer. The risk factors, pathogenesis and treatment options of corneal hydrops are discussed. METHOD This is an observational case report study. RESULTS A 77-year-old man presented with a 1-day history of severe pain, rednes...
