Analysis of refractive errors and strabismus deviations following the visual screening of patients with the Welch Allyn Spot device. This paper is a prospective cross-sectional study of 4281 patients examined with the Welch Allyn Spot device acquired by . The study was conducted between May 2019 and August 2021 and was performed with the help of . In the present study, 4281 patients were evaluated and divided into 5 age groups (6-12 months, 12-36 months, 3-6 years, 6-20 years, and 20-100 years). The most frequent age group was 6-20 years, being identified in 51,97% of participants. We found that the most common refractive error was astigmatism, followed by hyperopia and myopia. Thus, (RE) the refractive errors found in the right eye were: astigmatism 93.23%, hyperopia 4.63%, and myopia 1.05%, and in the left eye (LE): astigmatism 90.40%, hyperopia 6.68%, and myopia 0.84%. Of all participants, 8.81% had horizontal strabismus, esotropia being found in the RE in 4.56% of the participants and the LE in 4.74% of them. The pediatric population was the most affected by astigmatism and esotropia. RE = right eye, LE = left eye, SD = strabismus deviation.

Purpose: To investigate the incidence of microbial keratitis among Japanese patients wearing orthokeratology (ortho-k) lenses STUDY DESIGN: Retrospective multicenter study METHOD: This study was conducted at 4 hospitals in Japan and involved 1438 patients who had been prescribed ortho-k lenses and had worn them for at least 3 months. Data on patient demographics, lens characteristics, lens care systems, and presence of microbial keratitis were extracted from the medical records. Duration of ortho-k lens wear was calculated from the original fitting date to the patient's last visit, with the total years of lens wear used as person-years of lens wear.

Purpose: To determine the physiological status of the retina by electroretinography (ERG) using skin electrodes and the RETeval system in eyes that had undergone pars plana vitrectomy (PPV) with silicone oil (SO) tamponade. The vitrectomy was performed for a retinal detachment and proliferative diabetic retinopathy (PDR).
