Objective: The objective of this study is to investigate factors associated with outcomes after 3 months of instructed usage of hand-held digital devices (DD) in patients with acquired comitant esotropia (ACE).

Methods And Analysis: This prospective multicentre observational study included patients with ACE, aged 5-35 years, who used DD within 1 year of onset and were followed up for clinical findings and instructed use of DD. The outcomes were classified into four groups: cured, improved, unchanged and worsened.

Long-chain fatty acid (LCFA) degradation primarily involves several species of and hydrogenotrophic methanogens, constituting the rate-limiting step in anaerobic digestion. It is crucial to augment their abundance to enhance LCFA degradation. Utilizing microbial carriers presents an effective strategy to maintain the microorganisms on the surface and prevent their washout from the digester.

Purpose: To compare the distance of the medial rectus muscle insertion to the limbus (DMIL) between patients with acute acquired comitant esotropia (AACE) associated with excessive digital device usage (EDDU) and exotropic patients.

Study Design: Retrospective study.

Methods: The medical records of 72 eyes of 44 patients with EDDU were retrospectively analyzed.

Purpose: Favorable stereoacuity does not develop in all patients with partially refractive accommodative esotropia (PRAET) successfully aligned, and there have been few previous reports on the factors influencing stereoacuity outcomes in patients with PRAET treated with prismatic correction (PPC) and/or surgery. This study aimed to analyze factors affecting stereoacuity outcomes in patients of PRAET treated with PPC and surgery.

Study Design: Retrospective study.

Article Synopsis
  • - Persistent fetal vasculature (PFV) is a congenital eye condition where the primary vitreous and hyaloid vessels fail to regress, causing abnormalities that can lead to cataracts and other complications.
  • - A novel surgical technique involving an intraocular endoscope was used safely in four cases of cataracts associated with PFV, allowing for better observation and treatment without significant complications.
  • - The use of the endoscope during surgery improved precision and effectiveness in managing the vitreous stalk and fibrovascular membranes, suggesting it as a valuable approach for PFV-related cataract treatment.

Visual field disorders caused by cerebral aneurysms are diverse, nonspecific, and vary in their degree of compression. They should be distinguished from those caused by other common diseases, such as glaucoma.

Purpose: To report a case of functional visual loss (FVL) diagnosed through bilateral randomized visual field testing using Imo vifa with a trick method.

Observations: A 27-year-old man complained of visual field abnormality in his left eye after falling from a height of 4 m. The left eye had a best-corrected visual acuity (BCVA) of 20/16 and a critical flicker frequency (CFF) of 44.

Purpose: To describe clinical presentations of acquired comitant esotropia and digital device use in children, adolescents, and young adults without neurological problems.

Study Design: Multicenter prospective observational study.

Methods: Patients with acquired comitant esotropia, without intracranial diseases aged 5-35 years at the time of visit, who were seen at pre-registered facilities within 1 year of onset were enrolled.

Purpose: The purpose of this study was to investigate the relationship among suppression scotoma size, stereoacuity, and four-prism base-out test (4ΔBOT) results in anisometropic amblyopia with successfully treated visual acuity.

Methods: We included 103 cases of anisometropic amblyopia successfully treated for visual acuity without strabismus. Stereoacuity was measured using a Randot Stereotest.

Purpose: To analyze surgical results of 32 cases with acute acquired comitant esotropia (AACE) related to prolonged use of digital devices (DDs).

Patients And Methods: Medical records of cases with AACE related to prolonged use of DDs that had undergone surgery were retrospectively revised. Complete medical history and full ophthalmological examinations before and surgery were obtained for all cases.

Objective: To determine the reliability of the Kinect-based semi-automatic scoring method (KSSM) using Kinect for Windows v2 for head posture compared to the cervical range-of-motion (CROM) device.

Methods And Analysis: Head positions between -40° and +40° of chin up/down (X), head turn (Y), and lateral tilt (Z) were measured in 10° increments in healthy volunteers. Their head positions were simultaneously measured using the KSSM and CROM.

Purpose: To clarify the relationship between stereopsis outcome and timing of surgical alignment in infantile esotropia.

Methods: The medical records of otherwise healthy patients with infantile esotropia who underwent surgery by 8 years of age were divided into the following groups according to age at time of surgery: very early surgery (≤8 months), early surgery (>8 to ≤24 months) and late surgery (>24 months). Binocular response and stereopsis were compared between groups.

Purpose: To investigate postnatal changes in the biorbital angle in normal Japanese children.

Subjects And Methods: Axial imaging of the orbit in the transverse plane of the horizontal extraocular muscles was obtained in 129 ophthalmologically healthy infants (age ranging from a few months to 11 years). The opening angle between both lateral walls of the orbit was defined as the biorbital angle.

Purpose: The purpose of this study was to clarify whether the timing of initial surgery for infantile esotropia contributes to better sensory outcomes and to the severity of dissociated vertical deviation (DVD).

Methods: This retrospective study examined 55 children, aged 8 years and younger, who underwent esotropia surgery. Based on age at the time of the surgery, patients were divided into the very early surgery group (birth to 8 months, N = 14), early surgery group (9-24 months, N = 23) and late surgery group (25 months and older, N = 18).
