PURPOSE: To assess comparatively the central corneal thickness (CCT), the central corneal endothelial cells density (CECD) and mean area (CECAA), of patients who underwent trabeculectomy (Trab) with or without mytomicyn C (MMC). METHODS: Prospective study. Twenty-nine eyes were divided in two groups: Trab with or without MMC. Ultrasonic pachymetry and non-contact specular microscopy were performed pre-operatively and three and six months after Trab. The mean value of the CECD and the low value of the CCT were used. RESULTS: In […]

The purpose of this paper is to describe the clinical aspects of one case with deep corneal vascularization after corneal ring implantation to treat corneal ectasia due to LASIK 4 years before. The corneal ectasia diagnostic was performed by corneal pachimetry and topography. Intrastromal corneal ring segment was implanted. On the third year of follow-up, extrusion of one segment was noted and deep corneal neovascularization was found. The segment was removed, laser photocoagulation was applied and complete vascular regression was […]

PURPOSE: Could the central corneal thickness (CCT) change the intraocular pressure (IOP) measured by ICARE (IC) GOLDMANN APPLANATION TONOMETER (GAT) and PASCAL DYNAMIC COUNTOUR TONOMETER (PDCT). METHODS: Before using the anesthesia we have measured the IOP with IC tonometer. After that we have used topical anesthesia to obtain the CCT using an ultrasound pachymeter (Mentor Co.) and the IOP measured by PCDT followed by a drop of fluorescein to measured IOP with GAT. RESULTS: 138 eyes of 71 patients were […]

PURPOSE: To compare measurements of central corneal thickness obtained using a Haag-Streit optic pachymeter and a DGH 500 (Pachette Ttm ) ultrasonic pachymeter in normal patients. METHODS: An evaluation was made of 200 eyes of 100 patients using Optic (PO) and Ultrasonic (PU) pachymeters. Measurements were made in the area of the central cornea (ECC) respecting the 3.0 mm territory, in patients with normal corneas of hypermetropic, emetropic and myopic eyes. Patients with ocular diseases, ocular surgeries, and contact lens […]

The aim of this article is to make a review about glaucoma associated with penetrating keratoplasty, describing since its incidence and risk factors until the different options for treatment.
