RESUMO O artigo tem como objetivo descrever de forma prospectiva diferentes casos de ectasias altamente assimétricas (very asymmetric ectasia, VAE) para diferenciar formas subclínicas ou “frustas” do ceratocone (forme fruste keratoconus – FFKC) de casos de doença ectásica unilateral. O Caso 1 é um paciente de 39 anos, que admitiu ter coçado intensamente apenas o olho direito (OD) na juventude, se apresentando com ectasia unilateral tratada com sucesso por meio de implante de anel intraestromal em OD. O olho esquerdo […]

Abstract Objective: To Perform a review on the diagnosis of keratoconus, focusing on the available propaedeutic methods. Methods: A search was performed in the PubMed database using the key words: Keratoconus, diagnosis, topography and tomography. As it is a review, there was no restriction regarding the publication period of the selected articles. Furthermore, both the preferred practice pattern(PPP) manual of the American Academy of Ophthalmology, as well as the website “eyewiki.aao.org” were used as reference. The project was submitted to […]

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 […]

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 […]

PURPOSE: The methodology currently used for interpretation of the cornea and anterior segment tomography for the diagnosis of corneal ectasia and its susceptibility. METHODS: Description of the methodology and clinical interpretation of corneal and anterior segment tomography indexes; report of three cases demonstrating the importance of this new diagnostic tool (Pentacam HR®) in ophthalmological practice. CONCLUSION: The use of corneal and anterior segment tomography seems to be an effective method to increase the sensitivity and specificity for the diagnosis and […]
