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.

Trata-se de um caso de ceratite bilateral e simultânea por Acremonium relacionada ao uso intermitente e sem respeitar a lateralidade do uso de lentes de contato gelatinosas. Houve diagnóstico tardio, apresentando resistência a anfotericina B e hipópio persistente, com resposta positiva a natamicina tópica. Além da forma incomum de apresentação, não houve histórico de trauma ou contato com material vegetal, associado à maioria dos casos de ceratite por fungos filamentosos.

Objective: To investigate the correlation between phenol red test and Schirmer tear test on tear quantification together with a questionnaire to detect symptoms of dry eye. Methods: A total of 49 patients were enrolled at this study. Each participant had its eyes examined by the two tests.The dry eye symptoms were evaluated by a total of 5 questions.The data were collected and analysed by Kappa statistical method to check the concordance between the tests. Results: A sum of 65.3% of […]

Objective: Describe the epidemiological profile of cornea donors in the state of Goiás. Methods: We used a random sample of 793 records calculated by the formula of Leslie Kish (Epi Info 7) taking into account a total of 3,093 records from January 2006 to August 2015. The data was analyzed using the Statistical Package for Social Sciences (SPSS) and the results were described using proportions, central tendency and dispersion measures. Comparisons between categorical variables were made using the chi-square test […]

Objective: To determine if the change in the shape of the corneal epithelial removal in photorefractive keratectomy (PRK), from circular to oval shape, modifies the recovery of the postoperative visual acuity (VA). Methods: Forty-three(43) patients subjected to bilateral simultaneous PRK were prospectively evaluated. Randomly for each patient, one eye underwent epithelial removal in circular shape and the other in oval shape. On the sixth day of postoperative period (D6) the follow items were recorded: the subjective comparative perception, informed by […]
