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 Duane Syndrome (DS) is a rare ocular disorder that causes congenital strabismus. It results from a failure of the abducens nerve (VI cranial nerve) to innervate the lateral rectus muscle, in addition to anomalous innervation of this muscle by the oculomotor nerve (III cranial nerve). The syndrome is characterized by restricted movements of adduction and abduction, narrowing of the palpebral fissure, abnormal ocular movements, and globe retraction. It affects about 0.1% of the population and accounts for 1-4% of […]

ABSTRACT Objective To analyze strabismus surgeries in children in Brazil over a 10-year period using Datasus, focusing on regional, temporal, gender, and age group variations. Methods A descriptive and quantitative study using data from Datasus (from January 2013 to November 2023), analyzing strabismus surgeries in children aged 0 to 14. Variables included gender, age group, region, and year of surgery. The research used public and anonymous data, eliminating the need for ethical approval. Results There was equal susceptibility between genders. […]

ABSTRACT Objective: To evaluate the effect of 0.2% brimonidine eye drops in reducing hyperemia and ocular bleeding during strabismus surgeries, in comparison with 0.025% naphazoline + 0.3% pheniramine eye drops. Methods: Fourteen patients with strabismus and indication for bilateral surgical correction were evaluated. Before the procedure, the eye drops were instilled randomly in each eye of the evaluated patients. The subjective analysis of conjunctival hyperemia and perioperative bleeding was performed in a double-blind manner, by 02 surgeons. The objective assessment […]

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 a new type of muscle hook (Felício’s millimeter hook) and its effectiveness in strabismus surgeries. Methods: Seeking an independent approach, with minimal assistance from the assistant, the new instrument was used in retrocession and resection surgeries, to compare its efficacy and safety with the traditional technique. Results: 14 patients participated in the study, divided into two groups. The group who underwent surgery with the traditional technique had a mean age of 14.7 years and the group […]

ABSTRACT Anomalous extrinsic ocular muscles are rare findings but they should be suspected in cases of atypical and excessively restrictive strabismus, associated with vertical movements or retractions. They can also be seen as perioperative findings in characteristically normal deviations. We report two cases in which anomalous lateral rectus muscle was found during surgery. In case one, a 29-year-old man had a mild abduction limitation and esotropia of 35 prismatic diopters in his right eye. In the perioperative period, anomalous division […]

ABSTRACT Purpose: To evaluate the quality of life of children with strabismus and understand their consequences in the functional and psychosocial aspects of the childhood. Methods: A semi-structured interview adapted of Adult Strabismus-20 questionnaire was conducted with parents or the legal responsible person of children aged between 3 and 13 years old attended at the public health care. A likert-scale of five points was used to measure the impact of strabismus in childhood, from psychosocial and functional aspects. Results: 97 […]
