ABSTRACT Lamb-Shaffer syndrome (LAMSHF) is a rare condition characterized by neurodevelopmental disorders caused by haploinsufficiency of the SOX5 gene on chromosome 12p12. Clinically, it manifests itself with growth retardation, global neurodevelopmental delay, speech delay, dysmorphic facial features, and musculoskeletal, cardiac, and genitourinary abnormalities. Although frequent, the ophthalmological presentations of this syndrome are not well established in the literature. In this study, we aim to report a new case of this rare condition, highlighting the ophthalmological aspects of its condition.

ABSTRACT Objective: To assess whether the anteroposterior diameter growth curve in Brazilian children aligns with the Caucasian-European standard used as a reference in Brazil. To evaluate the feasibility of using non-cycloplegic refractometric measurements from an autorefractor based on the anteroposterior diameter for medical prescription. Methods: A prospective, cross-sectional pilot study was conducted with children receiving care through the Brazilian Unified Health System at the Hospital de Olhos do Paraná. Examinations included visual screening, anamnesis, cycloplegic refraction, fundoscopy, measurement of the […]

ABSTRACT This study reviews the scientific literature on global opinion surveys to analyze the perceptions and practices of eye care professionals in myopia management and prescription trends. Fourteen studies published between 2018 and 2024 were included, using search terms such as Myopia, Surveys, Attitudes, Opinions, Myopia Control, Management, and Progression. The results indicate a growing concern about the increasing prevalence of myopia, reflected in the broader adoption of evidence-based strategies, particularly behavioral interventions for progression control. However, a significant number […]

ABSTRACT Objective: To identify, care for and report on the experience of combating visual disorders of schoolchildren in the countryside of Bahia. Methods: Experience report on visual triage, using the Snellen table, conducted in public schools with students from the 2nd to the 4th grade of elementary school in the city of Feira de Santana (Bahia). Referral criteria for ophthalmological consultation were Detection of visual acuity equal to or less than 20/30 in one eye; presence of complaints or external […]

ABSTRACT Purpose: To evaluate the prevalence of refractive errors (RE) in children and their association with age group, sex, and racial variations before the COVID-19 Pandemic. Methods: This retrospective cross-sectional study involved 1,086 children with a mean age of 9.1 years (0-15 years) who underwent refraction examination under cycloplegia between 2015 and 2019. Myopia was defined as Spherical Equivalent (SE) −0.50 diopters (D) or more; hyperopia as +2.0 D, and astigmatism as at least −0,50 D. The RE were further […]

ABSTRACT Objective: To know the prevalence of visual impairment in children from pre-selected public schools, as well as to analyze and intervene in it. Methods: The study was conducted in four stages. During the first and second ones, school professionals and medical students were trained in visual screening to perform the visual acuity of children in the first years of Elementary School. Children with altered acuity received ophthalmologic referral for diagnosis and intervention. Results: Of the 450 children screened, 64 […]

ABSTRACT Objective To evaluate intraocular lens power calculation and postoperative refractive errors in patients with high myopia undergoing cataract surgery, comparing predicted target refraction and actual postoperative refraction measured 30 days after surgery with SRK/T formula. Methods This retrospective analysis comprised 39 eyes of 31 patients undergoing cataract surgery through phacoemulsification with in-the-bag IOL implantation. Axial length was measured by partial coherence interferometry or immersion ultrasound biometry, with measurements greater than 26 mm and preoperative myopia greater than -6.0 D […]

ABSTRACT Objective: To study vertex-optical distance variation and estimate its impact on manifest refraction. Methods: Prospective study in a private clinic using the Vision-S™ 700 with five forehead positions. Forehead on the third position showed the closest vertex-optical distance of 12mm. Results: Analysis of 52 eyes from 26 patients revealed mean differences in vertex-optical distance of 12.25mm (right eye) and 11.75mm (left eye). A 2mm change in vertex-optical distance resulted in a 0.05D change for a 5D spherical equivalent and […]
