Evaluation of the impact of binocular versus monocular cataract surgery using Catquest-9SF: a randomized controlled trial.

Purpose: This prospective, randomized, unmasked, clinical trial aimed to report the visual outcomes of cataract surgery on both eyes versus cataract surgery on one eye in Brazilian patients.

Methods: This study included patients with bilateral cataracts and binocular visual acuity worse than or equal to 0.3 logarithm of the minimum angle of resolution.

Impact of pterygium on central corneal thickness measured by optical coherence tomography in older adults.

Purpose: To measure the central corneal thickness (CCT) using anterior segment optical coherence tomography (AS-OCT) in older adults with and without pterygium from the Brazilian Amazon Region Eye Survey (BARES).

Methods: BARES is a population-based epidemiological cross-sectional study conducted in Parintins city. Participants were residents ≥45 years of age identified through a door-to-door interview.

Catquest-9SF questionnaire: validation of the Portuguese version using the Rasch analysis.

Purpose: The aim of this study was to validate the Portuguese version of Catquest-9SF through its application in a native Brazilian population with cataracts and to determine the correlation of the questionnaire scores with preoperative visual acuity.

Methods: A prospective study was conducted to validate the Catquest-9SF questionnaire, which was translated and back-translated, generating a final version in Portuguese. A total of 120 Brazilian patients awaiting cataract surgery were recruited to answer the questionnaire and to document their preoperative data and visual acuity.

Psychometric properties of CVFQ7-BR-toxo to evaluate vision-related quality of life in children with congenital toxoplasmosis in Brazil.

Purpose: The high prevalence and severity of congenital toxoplasmosis in Brazil, with several affected individuals progressing to low vision, emphasize the importance of evaluating their quality of life. In this study, the Children's Visual Function Questionnaire (CVFQ) was adapted to the sociocultural context of Brazilian children, and its psychometric properties were investigated for evaluating the vision-related quality of life of these individuals.

Methods: This was a nested cross-sectional epidemiological study that prospectively monitored a cohort of 142 preschool children at a single referral university hospital in Belo Horizonte, Brazil.

Ophthalmic artery resistance index after peribulbar block in the presence of epinephrine.

Purpose: There are controversies regarding ophthalmic artery (OA) flow after peribulbar block in the presence of epinephrine. Therefore, we aimed to evaluate OA flow via echo-Doppler before and after peribulbar block with lidocaine in the presence or absence of epinephrine.

Methods: Fifty-six patients who had an American Society of Anesthesiologists (ASA) classification of I, II or III and were eligible for cataract phacoemulsification surgery were selected.

Corneal ectasia and high ametropia in an infant with microcephaly associated with presumed Zika virus congenital infection: new ocular findings.

We report the first case of a corneal ocular ectasia in an infant with Zika virus congenital infection (CZS). We suspect that the ocular embryology and neurotropism of the Zika virus could account for the corneal involvement.

Population-Based Cataract Surgery Complications and Their Impact on Visual Status in the Brazilian Amazon Region.

Purpose: To investigate cataract surgery prevalence, complications, visual outcomes, and coverage in a population of older adults from the Brazilian Amazon region.

Design: Population-based cross-sectional study.

Methods: Individuals ≥45 years of age from urban and rural areas of Parintins City, Brazil, were identified by cluster random sampling.

Presbyopia and Ocular Conditions Causing Near Vision Impairment in Older Adults From the Brazilian Amazon Region.

Purpose: To investigate the prevalence and causes of near vision impairment (NVI) in a population of older adults from the Brazilian Amazon Region.

Design: Population-based cross-sectional study.

Methods: Cluster sampling was used in randomly selecting subjects 45 years of age and older from urban and rural areas of Parintins city, Brazil.

Instruments for evaluation of functionality in children with low vision: a literature review.

We conducted a literature review of tools used to evaluate functionality in children with low vision with the aim of analyzing the applicability, advantages, and disadvantages for children <6 years of age, an age at which visual development is mostly complete. Publications in Portuguese, English and, Spanish describing functional evaluation tools for children aged 0-18 years with low vision in the following databases were included: Web of Science, Virtual Health Library, Cochrane, Scielo, and PubMed. A total of 181 articles were collected, 15 of which were included in this review.

Causes of visual impairment in children seen at a university-based hospital low vision service in Brazil.

Purpose: To evaluate the epidemiologic characteristics of patients 0-7 years of age with visual impairment registered at a university hospital low vision service in Brazil.

Methods: The medical records of visually impaired patients were retrospectively reviewed for sociodemographic characteristics and ocular and associated deficiencies. In addition to biographical information, the following data were collected: ocular disorders, diagnosis, affected anatomic region, etiology, and avoidable or unavoidable causes.

[Functional vision assessment in children with low vision from two to six years of age - a comparative study].

Purpose: The Functional Vision Assessment (AVIF-2 to 6 years)'s capacity to differentiate visual ability levels in children with low vision was analyzed. The AVIF-2 to 6 years was created at the Infantile Low Vision Sector from São Geraldo Hospital, Brazil.

Methods: After a debate among professionals from different areas regarding the appropriateness of the test items, AVIF-2 to 6 years was applied to 40 children aged from 2 to 6 years; twenty children with low vision (Group 1) and twenty without it (Group 2) were assessed.

[Surgical treatment of acquired restrictive strabismus in infancy: case report].

The authors describe a severe and rare case of restrictive strabismus, acquired during the first semester of life, in a previously normal baby. They discuss the possibility of inflammatory or infectious disease as the primary cause. Surgical management was challenging, after three procedures and required the cooperation of strabismus and orbit specialists and also a wide incision for orbital surgery.
