PURPOSE: To compare topographic features of patients with keratoconus between two systems: Orbscan IIz® (Bausch & Lomb, Rochester, New York, USA) and Wavetek Chroma®. METHODS: Twenty-nine patients that were diagnosed with keratoconus based on clinical and topographic characteristics were evaluated on their visit to Ophthalmology Hospital of Sorocaba in March 2010. Topographic variables, like maximum and minimum keratometric readings (Sim K) within 3 and 5 mm of central zone, and maximum keratometry, were analyzed by Orbscan IIz® and Wavetek Chroma®. […]

PURPOSE: To describe the epidemiological profile of patients waiting for penetrating keratoplasty in state of Pará, Brazil. METHODS: Transversal and retrospective study, with 1261 patients, in the period of january 2001 until to december 2009, were registered on the waiting list for corneal transplantation in the Central Notification, Captation and Distribution of Organs (CNCDO) of Pará.

The aim of this report is to describe a case of iridocornel endothelial syndrome with the clinical variant essential iris atrophy, which presents concomitant congenital hypertrophy of the retinal pigment epithelium in the same eye.

PURPOSE : To demonstrate the reduction and prediction of refractive errors after penetrating keratoplasty (PK) for keratoconus and evaluate the effect of recipient-donor trephine disparity on the results. METHODS: Retrospective analysis of clinical records of 60 patients that underwent PK for keratoconus performed by the same surgeon, under the same technique, between 2005 and 2009. Spherical equivalent, keratometry and visual acuity were evaluated statistically before surgery and 1.3 and 6 months after. The patients were divided in two groups according […]

PURPOSE: Evaluate the effect of micro puncture with radiofrequency as treatment of symptomatic patients with bullous keratopathy. METHODS: Prospective study in 10 pacients with syntomatic bullous keratopathy and low vision. Micro puncture with radiofrequency was made in areas of the anterior stromal that had an epithelial descompensation. The evaluation of the patients was realized trough clinical examinations (biomicroscopy, pachymetry, tonometry and esthesiometry) and symptom graduation (pain intensity, foreign body sensation, photophobia and insomnia caused by pain). RESULTS: The comparisons of […]

Cornea intraepithelial dysplasias are lesions with low risk of malignancy within the spectrum of intraepithelial neoplasia of the ocular surface. These areas are presented as dysplasias or leukoplasias and are associated with the presence of human papillomavirus (HPV), a major risk factor. In this report, the authors describe a case of a corneal intraepithelial dysplasia treated by surgical excision, with histological confirmation and negative DNA hybridization for HPV.

PURPOSE: To determine and compare with the literature data related on age, sex and the main indications for penetrating keratoplasty at the São Geraldo Hospital of Federal Universidade of Minas Gerais (UFMG), from january 1999 until december 2005. METHODS: A retrospective analysis was performed using data from 887 patients submitted to corneal transplantation from january 1999 until december 2005. These data were obtained from the archives of the Central Notification of State of Minas Gerais, MG-Transplantes database, and from the […]

Objective: Analyze and identify critically the profile of patients with aphakic/pseudophakic bullous keratopathy attended at a public hospital. Methods: Retrospective analysis of 35 eyes of 35 patients with diagnosis of bullous keratopathy, which has been followed in the department of cornea and external diseases of Hospital da Piedade. The one whose pre and per operative data we did not find were excluded. This selection of patients was done from January to June of 2007. Results: As main results we found […]
