ABSTRACT The term dysfunctional lens syndrome has gained acceptance in the field and encompasses natural changes due to aging of crystalline lens. The evolution of diagnostic devices has been a key factor in better staging, understanding and characterizing of these degenerative changes. Even with these technological advances and the use of subjective classifications, such as the classic Lens Opacities Classification System, an objective staging of early dysfunctional lens syndrome has yet to be established. Ocular wavefront aberrometry and objective scatter […]

ABSTRACT Purpose: To compare the accuracy of best-corrected visual acuity in patients with diabetic retinopathy to corrected visual acuity ≤ 20/200 in both eyes, measured by Snellen and ETDRS charts, in addition to evaluation of reading time by Jaeger chart. Methods: An observational and cross-sectional study. Study Groups: Group I, patients with visual acuity 20/200, and Group II, patients with visual acuity >20/200. Patients were subdivided into those with non-proliferative diabetic retinopathy and with proliferative diabetic retinopathy. The study variables […]

ABSTRACT Ocular toxoplasmosis frequently presents as necrotizing retinochoroiditis and, less often, as peripapillary chorioretinitis and/or papillitis. The progression from papillitis to peripapillary retinochoroiditis has been rarely described. We report the case of a 52-year-old patient living in southern Brazil, who developed papillitis in the right eye and was treated with systemic corticosteroids (prednisone 0.6 mg/kg/day and pulse therapy with methylprednisolone 15 mg/kg/day, for 3 days). After 14 days, the patient developed peripapillary retinochoroiditis with vitritis and decreased visual acuity (20/60), […]

ABSTRACT Traumatic chiasmal syndrome is one of the rare etiologies of chiasmal syndrome, characterized by optic chiasm injury following head trauma. The main visual defect associated is bitemporal hemianopia with macular splitting; however, it can present with a variety of other visual defects and neurologic signs. The authors report a case of complete bitemporal hemianopia after head trauma, with multiple frontal and skull base fractures and no other neurologic deficits, or hypothalamic-pituitary abnormality. Most cases of traumatic chiasmal syndrome are […]

ABSTRACT Objective To compare the performance of Sanders-Retzlaff-Kraft/Theoretical, Hoffer Q, Barrett Universal II, Kane, and Hill-radial basis function formulas to calculate intraocular lens power in eyes with normal axial length, in terms of predicting target refraction by using partial coherence interferometry technology. Methods Phacoemulsification and intraocular lens implantation were performed in 135 eyes of 135 patients with an axial length between 22 and 24.5 mm. Axial length, keratometry, and anterior chamber depth were measured by intraocular lens Master 500. Sanders-Retzlaff-Kraft/Theoretical, […]

ABSTRACT Objective To evaluate the population awareness of glaucoma. Methods A cross-sectional, descriptive, non-controlled study, using a questionnaire to collect data. The questions addressed sociodemographic profile and glaucoma, and were asked to individuals, before and after the presentation of an educational video on glaucoma. It was conducted in the city of Fortaleza (CE) and the respondents spontaneously decided to participate in a glaucoma prevention campaign. Results A total of 153 questionnaires were collected; in that, 130 were considered eligible, including […]

ABSTRACT We report 13 cases of large angle sensory strabismus treated with autologous graft of extraocular muscle. Recession-resection procedure of the horizontal rectus muscles was performed, and the flap from the resected muscle was sutured to the weakened muscle as an autologous expander. Six cases of exotropia and seven of esotropia, with mean prism diopter deviation of 75 (range of 70-90). There was significant improvement in the postoperative deviation, and mean prism diopter of 10.07 (range of no deviation to […]

O ensino oftalmológico na graduação médica é um momento muito importante na formação do aluno. É o primeiro contato formal no aprendizado da especialidade e, talvez, o único para a maioria que não vai seguir a carreira de oftalmologia. Nesse momento, ele aprende sobre a importância da visão, o quanto ela impacta na qualidade de vida das pessoas, as patologias oculares e como tratá-las, mas principalmente sobre sua correlação com inúmeras doenças sistêmicas. Nas palavras do Emérito Professor Newton Kara […]
