PURPOSE To determine the optimal conditions for enhancing corneal allograft survival by oral immunization with donor-specific alloantigens. METHODS CB6F1 mice were orally immunized with various doses of C3H/Hej corneal epithelial and endothelial cells before receiving orthotopic C3H/Hej corneal allografts. Paraformaldehyde-fixed corneal cells were compared with viable corneal cells for their ...

The aim of this study is to investigate the effect two antiglaucoma procedures, namely trabeculectomy and Ex-PRESS mini-shunt insertion on biomechanical properties cornea. This a prospective study. Thirty patients (30 eyes) were included in Nineteen eyes had an shunt inserted (Group 1) 11 2). examination time points for both groups one three weeks preoperatively at month 1, 6, 12 postoperativel...

IMPORTANCE Corneal anesthesia is recalcitrant to conventional treatment and can lead to permanent visual loss. OBJECTIVE To assess the outcomes of a novel sensory reconstructive technique for the treatment of corneal anesthesia. DESIGN, SETTING, AND PARTICIPANTS This prospective study evaluating a new technique was conducted at a tertiary referral center. Four eyes in 3 patients with cornea...

Diabetic keratopathy is an ocular complication that occurs with diabetes. In the present study, the effect of diabetic keratopathy on corneal optical density, central corneal thickness, and corneal endothelial cell count was investigated. One hundred and eighty diabetic patients (360 eyes) were enrolled in the study during the period from March, 2012 to March, 2013. The patients were divided in...

Objective: To compare the corneal stromal demarcation line depth after Epithelium-On and Epithelium-Off crosslinking in patients with keratoconus using anterior segment Optical Coherence Tomography (AS-OCT).
 Study design: Quasi-experimental study.
 Place Duration of Study: Armed Forces Institute Ophthalmology, Rawalpindi Pakistan from Jun 2018 to 2019.
 Methodology: This study i...

PURPOSE To study the intraocular pressure (IOP), the corneal thickness and the corneal curvature distribution in a normal population. To investigate the relation between these variables, and to determine if the IOP and the paquimetry will be modified by the refractive error and age. METHODS A population of 273 subjects, 545 eyes, without ocular pathology was selected. The refractive error, th...

Purpose: This study examines agreement between the devices Anterion® and Pentacam HR® used for corneal pupil measurements in healthy eyes. Methods: The parameters compared two were: anterior Km (D), K2 K1 axis (°), astigmatism K max posterior CCT (μm), thinnest point thickness X-coordinate (mm), Y-coordinate diameter center-corneal vertex distance (mm) (angle kappa), centroid angle (mm).
