ABSTRACT Objective: To evaluate parents’ knowledge and perceptions about amblyopia and its treatment after their child’s diagnosis. Methods: A cross-sectional study included parents of 30 children diagnosed with amblyopia, recruited from a pediatric ophthalmology clinic. Participants completed a questionnaire after the diagnosis of their children, before receiving amblyopia education. The questionnaire assessed parental knowledge, socioeconomic background, and barriers to care. Statistical analyses included descriptive statistics and logistic regression to identify factors associated with awareness and adhesion. Results: Most parents (85.7%) […]

ABSTRACT Objective: To translate and validate the Adult Strabismus Quality of Life Questionnaire into Brazilian Portuguese. Methods: A cross-sectional study for linguistic and cross-cultural validation of the Adult Strabismus Quality of Life Questionnaire in order to assess the quality of life in patients with strabismus. We have followed previous published guidelines on translation process to ensure the equivalence between the original and translated versions. The final version was applied in a pilot study to evaluate concordance and its reliability and […]

ABSTRACT Objective: To evaluate the effectiveness of text messaging in improving adherence to occlusion therapy for amblyopia. The secondary objective was to correlate the responses given in a self-reporting questionnaire with treatment outcome (improvement in visual acuity). Methods: This is a prospective, randomized, blinded clinical trial. The patients’ parents or legal guardians in the intervention group received text messages reminding them of the importance of patching. The control group received no text messages. At final evaluation, after a period of […]

ABSTRACT Hyperplastic primary vitreous persistence, currently referred to as fetal vasculature persistence, is a congenital anomaly that results from non-regression of the primary vascular vitreous and hyaloid artery system during embryogenesis. It is a unilateral anomaly in the vast majority of cases, sporadic and commonly not associated with any other systemic finding. Clinically, this condition can be classified into anterior and posterior persistence of fetal vasculature. The anterior condition is related to the ciliary artery system, while the persistence of […]

ABSTRACT Myelinated retinal nerve fibers are rare congenital anomalies that appear as gray-white patches. They may be present in a syndrome characterized by ipsilateral myelinated retinal nerve fibers, myopia and amblyopia. The author reported an ellipsoid zone defect on spectral domain optical coherence tomography in a case of Straatsma syndrome without macular extension.

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 […]

ABSTRACT Purpose: to compare the Subfoveal choroidal thickness (SFCT) and Retinal Nerve Fiber Layer Thickness (RNFL) of amblyopic and normal fellow eyes. Design: Prospective, cross-sectional, observational case series. Methods: Forty patients age 12 to 41 years (mean 23.73 ± 6.42) with unilateral amblyopia were studied. Among them, 11(28.2%) patients had amblyopia secondary to strabismus and 29(71.8 %) had anisometropic amblyopia. Optical coherence tomography (OCT) of the peripapillary RNFL thickness of amblyopic and fellow eyes was performed. RNFL thickness measurements were […]

ABSTRACT Objective: Evaluate the sensitivity, specificity e accuracy of the ocular refraction measured by the 2WIN® photoscreener as a screening method to identify children in need of spectacles prescription according to the criteria published by the Brazilian Society of Pediatric Ophthalmology (BSPO) in asymptomatic children, 6 to 36 months old, and determine the impact of cycloplegia in the sensitivity, specificity and accuracy of this method. Methods: One hundred seventy-eight (178) eyes of asymptomatic children between the ages of 6 and […]
