Purpose: To compare the ultrasound biometry measurements between immersion and contact techniques. Methods: The biometry was made in 60 eyes by the same examiner, using the contact and immersion techniques in each eye. Results: The lower mean axial length (23,16 mm) was found in the contact technique, and the greater (23,29) was found in the immersion technique, using the same probe. The lower mean standard deviation between recurrent measures in the same eye was found in the immersion technique, and […]

Objetivo: Comparar a sensibilidade ao contraste e análise de “wavefront” com OPD-scan em pacientes submetidos a cirurgia de facoemulsificação com implantes de lentes intraoculares AcrySof SN60D3 multifocal, AcrySof SN60WF monofocal asférica e AcrySof SA60AT monofocal esférica. Métodos: Trinta e dois olhos com a lente intraocular multifocal, 32 olhos com a lente intraocular monofocal asférica e 32 olhos com a lente intraocular monofocal esférica. A avaliação oftalmológica foi realizada no primeiro, terceiro, sétimo, e nonagésimo dia pós-operatório. Todos os exames foram […]

Purpose: Compare the OPD-scan results and the contrast sensitivity in patients who had implantation of the AcrySof SN60D3 multifocal IOL, the AcrySof SA60AT spheric monofocal IOL and the AcrySof SN60AT aspheric monofocal IOL. Methods: Thirty-two eyes received the multifocal IOL, 32 eyes received the spheric monofocal IOL and 32 eyes received the aspheric monofocal IOL. They were closely paired in age, sex, pre-operative wavefront analysis and contrast sensitivity. All patients was tested with the OPD-scan aberrometer, ETDRS chart at 100% […]

Purpose: To evaluate the results of the trabeculotomy-trabeculectomy combined procedure in 12 to 50 years old patients with moderate and advanced glaucoma. Methods: Nineteen eyes of thirteen patients underwent a trabeculotomy-trabeculectomy procedure and were prospectively analyzed and followed up for 21,6 ± 7,2 (5,1 a 29,7) months. Results: IOP was reduced from 32,03 ± 10,01 (12 to 50) mmHg to 9,42 ± 3,50 (2 e 16) mmHg with the number of topical medications being reduced from 1,47 ± 1,54 (0 […]

Purpose: Comparison of the skill to teach the direct ophthalmoscopy class supported by fellows of medical graduation course using two examination methods: conventional ophthalmoscope and wide field ophthalmoscope (panoptic). Methods: Assessment of the competence to learn using a survey after eye fundus examination with conventional ophthalmoscope and wide field ophthalmoscope (panoptic). The group searched was composed of 60 students of university medical graduation course. The survey was applied during the first and eighth week of ophthalmogical class of medical graduation. […]

We report a case of optic disc melonocytoma associated to subretinal neovascular membrane. The patient presented with low visual acuity, serous retinal detachment with haemorrhage and exudates and was referred with the diagnosis of melanoma and an orientation to enucleate the eye. We discuss the major aspects of both tumors and the details of differential diagnostic.

Von Hippel-Lindau (VHL) disease is an autossomical, dominant inherited tumour syndrom. These tumours may include haemangioblastoma in the retina and central nervous system (CNS), renal cell carcinoma, phaeochromocytoma, islet cell tumours of the pancreas, cystadenoma in the kidney, pancreas, and epididymis. The most common symptoms include: loss of vision, raised intracranial pressure, neurological deficits, paroxysmal raised blood pressure and local pain. We report herein a 29-year-old man with visual loss and cerebellar haemangioblastoma that despite neurological manifestations the diagnosis of […]

A fifty nine years old female presented a painful proptotic left eye for thirty days. Computed thomography of the orbits disclosed an orbital mass associated with osteolysis and intracranial invasion. Biopsy of the orbital tumor revealed the diagnosis of hepatocellular carcinoma. Computed tomography showed the liver as the primary site of the tumor. Chemoterapy induced a significativ reduction of the orbital tumor. After four months, the orbital tumor increased its size and the pacient died ninetheen months after the diagnosis.
