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...

purpose : to report an unusual presentation of chandler syndrome case report : a 22-year-old female came to our clinic with complaint of progressive visual loss in her left eye since three days ago. she had a history of trauma with finger-nail to her left eye eight days ago and had been managed with topical antibiotic. in her examination, the left eye had visual acuity (va) of counting finger a...

INTRODUCTION Corneal edema delays early visual recovery after phacoemulsification surgery in diabetes mellitus. OBJECTIVE To compare corneal edema of eyes in patients with type II diabetes mellitus and in non-diabetics after phacoemusification surgery. MATERIALS AND METHODS A hospital-based, retrospective study involving 96 eyes that underwent phacoemulsification surgery for immature catara...

BACKGROUND This study aims to present the management and clinical findings of a case of corneal wasp sting and to report the outcome of corneal change and panuveitis after vitrectomy. FINDINGS Clinical findings, anterior segment photographs, corneal endothelial changes, and medical treatment of corneal wasp sting-induced panuveitis are presented. A 95-year-man was stung by a wasp on his left ...

BACKGROUND Corticosteroids seem to affect the functions of corneal endothelial cells directly in addition to their anti-inflammatory effect. CASE A 69-year-old man presented with blurred vision in his left eye and decreased visual acuity in both eyes. He had received anterior-posterior radial keratotomy for myopia in both eyes 40 years earlier. OBSERVATIONS Both eyes showed mild corneal str...

The effect of corneal edema and the effect of penetrating keratoplasty upon the accuracy of electronic applanation tonometry were studied in rabbits. Pressure readings made directly from cannulas in the anterior chamber correlated well with those made by electronic applanation tonometry both in severe corneal edema and 24 hours after penetrating keratoplasty. The advantages of electronic applan...

Visual function was assessed by classic acuity measures as well as contrast thresholds over a wide spatial frequency range for subjects with experimentally induced corneal distortion and induced corneal edema. These results were compared with similar results for patients with uniocular keratoconus, bilateral keratoconus, and allied corneal pathology. Distortion and edema were found to produce c...
