Abstract In children, optic disc drusen (ODD) are often mistaken for papilledema, this being the prin-cipal differential diagnosis. This report describes the case of an 11-year old patient with ODD, in which the condition was initially diagnosed as papilledema, and the patient referred for pulse therapy. Fundoscopic examination is important because it is the first examination conducted by the ophthalmologist that is capable of revealing some characteristics of ODD that will aid in the differentiation between this disease and papilledema.

Abstract We report here the case of E.R.S.S. female, 43 years old, diagnosed with bilateral coloboma of choroid and retina, in order to emphasize the importance of preoperative exams, even a good shot of light projection, which is often being relegated to a negligible level in ophthalmological practice.We emphasize also that the ultrasound examination prior to the surgical indication is of paramount importance, however,this should be performed by experienced professional and the correct interpretation must be thoroughly searched for interpretative […]

Objectives: Determine if retrobulbar optic nerve horizontal diameter measurement or reflectivity correlates with the optic disc excavation diameter relation in glaucoma, considering: measurements correlation, the sensitivity and specificity between the methods and which value has greater sensitivity and specificity to differentiate patients with and without glaucoma. Methods: In a masked study, the optic nerves of 38 patients with open angle primary angle glaucoma and 37 control patients were examined for retrobulbar echographic determination of their A mode (DNA) and their […]

We described a rare association between peripapillary staphyloma and optic disk drusen in a woman with 47 years old and normal vision.

Objective: This work had the objective of reviewing the literature on the evaluation and detection of intracranial hypertension through optical nerve ultrasound. Method: literature review based on a bibliographic survey in the electronic databases: PubMed, LILACS, SCIELO and CINAHL, using the following descriptors: Intracranial Hypertension.Optic Nerve. Ultrasonography, its correspondents in Portuguese and their intersections. We selected 27 articles published in the period of 1998-2017. Results: the articles indicated that ultrasonography of the diameter of the optic nerve sheath (ONSD) is […]

Purpose: To correlate clinical findings of Vogt-Koyanagi-Harada disease with standardized echography findings in a cross-sectional, descriptive and observational study. Methods: Patients with Vogt-Koyanagi-Harada disease in the convalescent and recurrence phases were evaluated with standardized ocular echography. Eyes with opaque media were excluded. Clinical findings were correlated with echographic data. Results: Thirty-seven eyes of 25 patients were included. Best corrected visual acuity was in average 20/100 (0.70 logMAR). Clinical findings included: sunset glow fundus (92%), pigment migration (92%), nummular chorioretinal depigmented […]

Objetivo: Correlacionar achados clínicos da síndrome de Vogt-Koyanagi-Harada com resultados ecográficos padronizado da doença em um estudo transversal, descritivo e observacional. Métodos: Pacientes com a doença de Vogt-Koyanagi-Harada, o convalescente e recorrência em fases padronizadas foram avaliados com ecografia ocular. Olhos com material opaco foram excluídos. Achados clínicos foram correlacionados com dados ecográficos. Resultados: Um total de 25 pacientes e trinta e sete olhos foram incluídos no estudo. A acuidade visual (AV) 20/100 foi em média 0.70 logMAR. Os achados […]

PURPOSE: To compare measurements of central corneal thickness obtained using a Haag-Streit optic pachymeter and a DGH 500 (Pachette Ttm ) ultrasonic pachymeter in normal patients. METHODS: An evaluation was made of 200 eyes of 100 patients using Optic (PO) and Ultrasonic (PU) pachymeters. Measurements were made in the area of the central cornea (ECC) respecting the 3.0 mm territory, in patients with normal corneas of hypermetropic, emetropic and myopic eyes. Patients with ocular diseases, ocular surgeries, and contact lens […]
