Objetivo: Comparar os resultados refracionais e de análise vetorial, das incisões relaxantes limbares (IRL) versus lentes intraoculares (LIO) tóricas no tratamento do astigmatismo corneano pré-existente por ocasião da facoemulsificação. Métodos: Estudo observacional longitudinal (série de casos) no qual foram avaliados 62 olhos de 31 pacientes consecutivos de catarata com astigmatismo corneano pré-operatório entre 0,75 e 2,50 dioptrias para ambos os olhos. Os pacientes foram aleatoriamente distribuídos entre 2 grupos: um submetido a implante de LIO AcrySof Toric™ em ambos os […]

The biostatistics has gained significant importance in recent years, being one of the mainstays of current scientific research. It has a series of concepts and rules that must be understood to carry out or analyze an article. In this review we will discuss some of main tools utilized in works of interest in ophthalmology, its applications and limitations.

Abstract Purpose: To verify the influence of two different intensities and volumes of resistance training on intraocular pressur. Method: Nineteen athletes boxers (13 male and 6 female; mean age of 22 ± 3 years) were randomly assigned to two different resistance exercise sessions: muscular endurance with 3 sets of 15 repetition maximum and muscular hypertrophy with 4 sets of 8 RM. The intraocular pressure was measured with a Perkins tonometer before, during and after the resistance exercise sessions. Data were […]

Purpose: To describe the epidemiological profile of patients waiting for penetrating keratoplasty in state of Pernambuco, Brazil. Methods: Transversal and retrospective study, with 871 patients, in the period of 06/01/2011 a 05/31/2012, were registered on the waiting list for corneal transplantation in the Central of Notification, Captation and Distribution of Organs (CNCDO) of Pernambuco. Registration forms of cornea receiving were used, adapted to the purposes of this research. Results: In relation to frequency, it was obtained 54% female, 35% aged […]

Objective: To evaluate the level of knowledge about glaucoma in a population randomly selected, so as to correlate with epidemiological and socio-cultural. Methods: We conducted a transversal analytical study by means of questionnaires containing general questions about glaucoma, patients participating in a campaign for awareness and prevention of glaucoma. Results: Of 200 respondents, 54.5% were female and 45.5% male, mean age 51 years and 11 months. Regarding race, 54% are brown, 29% white and 17% were black. 85% reporting having […]

Case report of a patient, with a thick cornea, for Fuchs dystrophy in its early stages, yet with preserved corneal transparency (subclinical corneal edema), associated with normal intraocular pressure (IOP) by Goldman applanation tonometry (GAT), which was however, the diagnosis of primary open-angle glaucoma on the basis of structural changes of the optic nerve. The tomographic study showed a pattern of spatial pachymetry compatible with subclinical edema. The corneal biomechanical study with ORA (Ocular Response Analyzer, Reichert ®) associated with […]

Dolichoectasia of the internal carotid artery (ICA) is a rare condition that may be associated with neuro-ophthalmic manifestations, such as loss of visual acuity and visual field resulting from compression of the optic nerve (ON). The aim is to report a 67-year-old male patient with primary open-angle glaucoma (POAG) with atypical evolution, asymmetry of cupping and increased pallor of the rim of the left ON, due to compressive optic neuropathy by the dolichoectatic segment. The diagnosis was based on clinical […]

Silent sinus syndrome is an acquired condition in which there is a gradual collapse of the orbital floor and inward retraction of the maxillary sinus (atelectasis of the maxillary sinus). This in turn may cause associated ocular occurrences of enophthalmos and hypotropia. This is a report of an 8 year-old boy with silent sinus syndrome and associated ocular motility disorders. The association between silent sinus syndrome and ocular motility disturbance has been recently described in the literature. However, this is […]
