OBJETIVO: Observar a eficácia da fluoresceína sódica intravenosa, na visibilidade do vítreo, durante a cirurgia de vitrectomia nos pacientes com retinopatia diabética. MÉTODOS: Quatorze casos consecutivos de cirurgia vitreorretiniana para hemorragia vítrea e descolamento tracional da retina secundário à retinopatia diabética, foram submetidos à injeção de fluoresceína intravenosa a 20%, 1 hora antes da cirurgia.As imagens de todos os passos das cirurgias foram gravadas. RESULTADOS: A fluoresceína corou de verde o vítreo periférico, base vítrea, hialóide posterior melhorando a visibilidade […]

OBJECTIVE: To observe the effectiveness of intravenous sodium fluorescein visibility in the vitreous during vitrectomy surgery in patients with diabetic retinopathy. METHODS: Fourteen consecutive cases of vitreoretinal surgery for vitreous hemorrhage and tractional retinal detachment secondary to diabetic retinopathy underwent intravenous injection of sodium fluorescein to 20% 1 hour before the surgery. The images of the steps of the surgeries were recorded. RESULTS: The sodium fluorescein stained green from the vitreous peripheral, vitreous base, posterior hyaloid, further improving visibility to […]

This article reports a case of a female five years old child with rare syndrome of Wilderwanck wich consists in a association of KlippelFeil syndrome and Duane syndrome and auditive hypoacusia. Ocular examination reveals alterations of cervical column, bilateral abduction limitations, aduction limitation of right eye associated with enophthalmos, palpebral fissure decrease, anisotropia in A, lateroversions esotropia and bilateral neurosensorial auditive hypoacusia. Our patient reveal an association of Klippel-Feil Syndrome type II with bilateral Duane Syndrome.

The authors describe one case of diabetic papillopathy. They used an intravitreal triamcinolone as an option of treatment.

Pseudotumor cerebri is a syndrome of increased intra-cranial pressure without a space-occupying lesion or ventriculomegaly in a patient with normal level of conscience and normal cerebrospinal fluid constitution. The terminology for the disorder has changed over the years in accordance with advances in diagnostic technology and insights into the disease process. When no secondary cause is identified, the syndrome is termed idiopathic intracranial hypertension. Patients are not uncommonly seen by ophthamologists since they present with papiledema, double vision and visual […]

PURPOSE: Demonstrate the possibility of changing the biomechanical behaviour of cornea stroma by usage of riboflavin associated with non-ultraviolet light. METHODS: Double blind prospective study. Twenty five porcine eyes enucleated 24 hours before the experiment, have been divided on the following groups : Riboflavin 0,1% with irradiation of blue light, Riboflavin 0,1% without irradiation of light , Riboflavin 0,5% with irradiation of blue light, Riboflavin 0,5% without irradiation of light and BSS with irradiation of light. RESULTS: Differences where noticed […]

The exposure to ultraviolet radiation is associated with the beginning of ocular pathologies like keratites, cataract, age-related macular degeneration and pterygium. This radiation is divided in 3 bands according to the wave length: Uv-A (320-400), Uv-B (290-320), Uv-C (100-290). The optic industry developed ultraviolet filters to intraocular lenses, contact lenses and spectacle lenses. PURPOSE: The issue of this work is to estimate the efficacy of ultraviolet contact lenses with high hydration. METHODS: Six types of high hydrated contact lenses from […]
