PURPOSE: to determine the prevalence of astigmatism and the change of the axis according to the age in an ophthalmology private clinic population in the city of Florianópolis, Santa Catarina, Brazil. METHODS: A retrospective, descriptive, cross-sectional study was carried out based on the analyses of medical files. Astigmatism was classified as a cylindrical equivalent <-0,5 diopter (D). Astigmatism with the rule was defined as 160° to 20° , oblique astigmatism as 21° to 69° and 111° to 159° , and […]

OBJECTIVE: To show visual and refraction results using multifocal diffractive apodized intraocular lens. METHODS: The study of 100 eyes of 50 patients with cataract, submitted to phacoemulsification with bilateral implant of multifocal diffractive apodized intraocular lens (IOL). Binocular visual acuity was evaluated with and without correction for near and distance, and refraction previsibility and frequency of wearing glasses. RESULTS: Visual acuity without correction for distance was e” 20/30 in 97.56% of eyes operated on and e” J2 in 100%, of […]

PURPOSE: Could the central corneal thickness (CCT) change the intraocular pressure (IOP) measured by ICARE (IC) GOLDMANN APPLANATION TONOMETER (GAT) and PASCAL DYNAMIC COUNTOUR TONOMETER (PDCT). METHODS: Before using the anesthesia we have measured the IOP with IC tonometer. After that we have used topical anesthesia to obtain the CCT using an ultrasound pachymeter (Mentor Co.) and the IOP measured by PCDT followed by a drop of fluorescein to measured IOP with GAT. RESULTS: 138 eyes of 71 patients were […]

PURPOSE: To report the profile of Coats’ disease patients, referred to exclude retinoblastoma. METHODS: Retrospective study of medical charts from ten consecutive patients. Data evaluated include age at diagnosis, gender, chief complain, disease stage, treatment and evolution. RESULTS: Mean age at diagnosis was 43.9 months. Eight patients had stage 3B of the disease, one stage 3A and one 2B. From the eight patients with total retinal detachment (3B disease), seven were managed by observation one was submitted to unsuccessful retinopexy. […]

The eyeball luxation is a dramatic phenomenon in which there is a forward displacement of the eyeball so that the eyelids spasmodically close behind it. There are many risk factors, non-related to trauma, but orbital contusions with optic nerve and extraocular muscles involvement carry the worst prognosis. The present paper reports a dramatic domestic case of globe luxation in childhood, its pathophysiology mechanisms and management.

The purpose of this paper is to describe the clinical aspects of one case with deep corneal vascularization after corneal ring implantation to treat corneal ectasia due to LASIK 4 years before. The corneal ectasia diagnostic was performed by corneal pachimetry and topography. Intrastromal corneal ring segment was implanted. On the third year of follow-up, extrusion of one segment was noted and deep corneal neovascularization was found. The segment was removed, laser photocoagulation was applied and complete vascular regression was […]

This article reports a case of a female child, nine-years old, with a history of proptosis and progressive decrease of visual acuity. At ophthalmologic exam presented: best corrected visual acuity 20/20 on the right eye and light perception on the left eye; biomicroscopic exam was normal, weakness of left superior rectus and left inferior oblique muscle, exotropia and hypotropia to the left. At indirect ophthalmoscopy exam, fundus was normal on the right eye and had left optic disc with edema. […]
