PURPOSE: To present biometric predictability, evaluating postoperative refraction and visual acuity in eyes submitted to multifocal intraocular lens implantation. METHODS: Retrospective study in 88 eyes of 50 patients, submitted to phacoemulsification with multifocal lens implant of three commercial brands: ReSTOR, ReZoom and Tecnis. For biometric examination were used: optic biometry associated to the use of tomography of anterior segment and Holladay II biometric formula. With postoperative refraction, visual acuity and implanted IOL, according to Holladay II formula, we calculated the […]

PURPOSE: To estimate if a complicated phacoemulsification is a risk factor for developing age related macular degeneration. METHODS: Retrospective case-control study with review of records of 1150 patients, that underwent phacoemulsification surgery between 1995 and 1999, performed by a single surgeon (T.C.) Qui square test, Fisher exact test, and Mann-Whitney test were used to perform statistical analysis. RESULTS: There were 224 participants who had cataract surgery on 297 eyes, and from this total, 240 were with no complication and 57 […]

In order to assure corneal transparency after injury the effective removal of myofibroblasts is fundamental. The corneal myofibroblasts display platelet activator factor receptor on its surface. The platelet concentrate is one of the richest sources of essential growth factors, reducing bleeding, inflammation, scaring time, thus speeding up the closing of the ulcers. We report a case which provides evidence of clinical improvement with concentrate platelet eyedrops on a non responsive trophic corneal disease.

The authors describe four rare cases of polychromatic posterior corneal dystrophy, not describe in national literature. The opacities are deep in the stroma, dotlike, polychromatic, uniform in size, distributed from limbus to limbus, leading no reduction in visual acuity. It is also presented a bibliographic review of pre-Descemet’s dystrophy.

To describe the diagnosis and management of a optic disc haemorrhage probably caused by an acute and spontaneous posterior vitreous detachment. A single case-report of an optic disc haemorrhage probably caused by an spontaneous posterior vitreous detachment, in order to discuss the diagnosis, management and prognosis. Optic disc haemorrhage regression was observed after 6 hours of evolution without relapsing signals during the subsequent registers. The Scanning Laser Ophthalmoscopy revealed as an advanced alternative and efficient method in the vitreous detachment […]

Report of a case of posterior persistent hyperplastic primary vitreous (PHPV) case on a nine years old patient with low visual acuity on the left eye, referred by the school for ophthalmic evaluation. The PHPV can embrace a wide spectrum of ocular alterations involving retina, vitreous, optic nerve, macula, crystalline, iris and ciliary body besides anomalies like mycroftalmia and microcornea. We point out the importance of early ocular evaluation in children, late diagnosis and late treatment, in order to minimize […]

The aim of this article is to make a review about glaucoma associated with penetrating keratoplasty, describing since its incidence and risk factors until the different options for treatment.
