Os autores fazem uma atualização da presença do espessamento de coroide, um achado de tomografia de coerência óptica com imagem de profundidade melhorada (EDI-OCT) empatologias retino-coroidianas como coroido-retinopatia central serosa, espessamento de coroide com neovascularização, vasculopatiacoroidianapolipoidal e espessamento de coróide com epiteliopatia.

A retinopatia aguda zonal oculta externa (AZOOR) é uma doença rara, caracterizada por um dano agudo de uma ou mais zonas da retina externa que levam ao comprometimento do campo visual ou da acuidade visual, estando associada a pequenas ou nenhumas alterações no exame fundoscópico. Os principais sintomas clínicos são escotomas e o aparecimento súbito de fotopsias. Resultados anormais de defeitos de campo visual e eletrorretinografia são críticos para o diagnóstico. A visão central é geralmente preservada e a estabilização […]

This article presents a review of the principles and clinical applications of the Scheimpflug principle in the anterior segment imaging. By providing a three-dimensional image of the anterior segment, this technology provides elevation and curvature data of the anterior and posterior surfaces of the cornea, pachymetric mapping, the total refractive power of the cornea and the anterior segment biometry. For the refractive surgery sub-specialty, this approach improves the ability to identify cases at risk of ectasia, as well as the […]

Choroidal folds is considered the most prevalent funduscopic finding in cases of orbital tumors. They are ripples in the retinal pigment epithelium, Bruch’s membrane, the inner portion of the choriocapillaris and in some cases, may affect the neurosensory retina, and then called chorioretinal folds. Several ocular and systemic conditions are associated with the finding and must be properly investigated and, if necessary, promptly treated. In this review we discuss the general aspects of choroidal folds, emphasizing their characteristic features in […]

The methodology currently used for interpretation of the cornea and anterior segment tomography for the diagnosis of corneal ectasia. Description of the clinical interpretation of anterior segment tomography (Pentacam – Oculus, Wetzlar, Germany); case report of the ectopia lentis demonstrating the importance o evaluation of the cornea and anterior segment of the keratoconus. We excluded the disease, analyzing the tomographic analysis of rates of ectasia and observe an asymmetry between nasal and temporal sides in assessing the depth map of […]

OBJECTIVE: To evaluate the safety of PRK in patients with atypical corneal topography, but without features of keratoconus in Pentacam. METHODS: Medical records of patients who underwent PRK method that presented atypical corneal topography and Pentacam rates considered normal in the pre operative were analyzed. The sample consisted of nineteen eyes of ten patients. The considered criteria of corneal irregularity were: increased curvature greater than 47D with asymmetry less than 1,5D, 1,5D displacement above the apex and inferior-superior asymmetry greater […]

O descolamento da membrana de Descemet pode ser uma complicação grave após a cirurgia de catarata, resultando em edema de córnea e redução da acuidade visual. Este relato descreve um caso raro de descolamento da membrana de Descemet seis meses após cirurgia de catarata com facoemulsificação sem intercorrências, documentado com tomografia de coerência óptica do segmento anterior (OCT; RTVue, Optovue). Foram realizadas descemetopexia pneumática e sutura corneana, com resolução do descolamento e recuperação visual. Este relato procura alertar os médicos […]

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 […]
