Apresentamos o caso de um paciente de 12 anos de idade com ceratocone avançado em ambos os olhos, que recebeu um tratamento em dois estágios no olho direito (OD) de modo a diminuir a taxa de progressão do ceratocone e reabilitar a visão do paciente. No exame clínico inicial, a acuidade visual sem correção no OD era contar dedos; refração sob cicloplegia era -22.00 – 7,50 x 100° = 20/400; a topografia demonstrou uma curvatura de 64,28 x 105° / […]

Corneal diseases account for about 4 to 5% of reversible blindness in the world. Corneal transplantation is the most transplanted tissue in the world and the only widely accepted treatment to promote corneal transparency and restore vision. Monitoring was incorporated into the field of Public Health, with the objective of systematically monitoring teams’ performance and production data, through the creation of norms, periodic evaluation inspections and monitoring of quality indicators. The critical analyzes of the results aim to point out […]

Introduction: Pterygium is a centripetal proliferation of fibrovascular tissue, which proceeds from the bulbar conjunctiva towards the center of the cornea. Excision of the pterygium may cause visual acuity improvement and surgical excision aims to achieve a topographically regular ocular surface. The improvement of the visual acuity results from the alteration of the refractive corneal power, that is measured in the topography as alteration of the topographic astigmatism. The objective of this study was to evaluate the variation of the […]

Pellucid marginal degeneration (PMD) treatment can be challenging in moderate to advanced cases and penetrating keratoplasty should be avoided due to high risk of complications, such as graft rejection. We report a case of a 30-year-old female patient with PMD that was referred to our service with bilateral low visual acuity, worse in her right eye and contact lenses intolerance. We performed a corneal crescentic lamellar wedge resection that resulted in good useful vision and postponed the keratoplasty for eighteen […]

A degeneração marginal pelúcida (DMP) é uma ectasia corneana de difícil manejo em casos moderados e avançados. O transplante de córnea penetrante nesses pacientes deve ser evitado ao máximo tendo em vista que a descentração necessária do botão aumenta o risco de vascularização e consequentemente rejeição, além das dificuldades técnicas e possibilidade de deiscência de sutura devido ao afinamento corneano pronunciado característico desta ectasia. Nós relatamos o caso de uma paciente de 30 anos com DMP com queixa de baixa […]

Objective: Analyze clinical data, therapy and tomographic parameters of patients attended at Fundação Hilton Rocha. Methods: This essay is a retrospective study based on a random sample of 150 patients submitted to cornea tomography and previous segment (Pentacam – Oculus, Wetzlar, Germany) at Fundação Hilton Rocha in the year 2015. The patients were classified as carriers or suspects of keratoconus through the following parameters: pachymetry, anterior and posterior central elevation, Ambrosio Relational Thinnest (ART), value of D and keratometry. After […]

Particle Swarm Optimization (PSO) is an artificial intelligence technique (AI) that can be used to find approximate solutions to numerical problems of maximization and minimization. In this study, it was used a PSO algorithm to compare displacements from human cornea sample subjected to internal pressure of 45 mmHg with Results of numerical simulations were provided which identified optimized values for hyperelastic properties of the cornea (µ and α). By means of the results from numerical simulations via inverse analysis by […]

This is a case of bilateral and simultaneous Acremonium keratitis related to intermittent and alternating eye soft contact lens use, which has a delayed diagnose, presented amphotericin B resistance with persistent hypopyon and had a positive response to topical natamycin. Besides the unusual presentation, there was no history of trauma or contact with vegetable matter, usually associated to the majority of cases of keratomicosys by filamentous fungi.
