Article Synopsis
  • The study investigated factors linked to myopia progression and axial elongation in children with myopia.
  • It analyzed data from a trial comparing atropine treatment with a placebo, focusing on children aged 5 to <13 with specific refractive errors and other characteristics.
  • Results showed that younger children and those with higher initial myopia experienced more significant changes in refractive error and axial length, highlighting the need for treatments to slow progression in this at-risk group.

Purpose: To test the impact of professional management of soft contact lens wear on symptoms and ocular complications.

Methods: Subjective symptoms and ocular complications of soft CL users who did not seek professional follow-up care (self-managed, SM), were compared to users who were prescribed CLs and their care professionally managed in optometry practices (PM), and to a control group of non-CL wearers. Habitual visual acuity, subjective dry-eye symptoms, and corneal abnormalities were assessed in all participants.

Purpose: To assess the long-term stability of clinical measures of convergence (near point of convergence [NPC] and positive fusional vergence [PFV]) in participants enrolled in the Convergence Insufficiency Treatment Trial-Attention and Reading Trial (CITT-ART) who received 16 weeks of office-based vergence/accommodative therapy.

Methods: A total of 310 children, 9-14 years old, with symptomatic convergence insufficiency were enrolled in CITT-ART. Some 270 completed both their 16-week primary outcome visit followed by a 1-year follow-up visit.

Significance: Clinicians and researchers would benefit from being able to predict the onset of myopia for an individual child. This report provides a model for calculating the probability of myopia onset, year-by-year and cumulatively, based on results from the largest, most ethnically diverse study of myopia onset in the United States.

Purpose: This study aimed to model the probability of the onset of myopia in previously nonmyopic school-aged children.

We evaluated whether doses of bilateral medial rectus recessions greater than Parks's tables yielded superior outcomes for adult-onset divergence insufficiency. Forty-two patients underwent bilateral medial rectus recessions. Dose was analyzed as the average total per muscle (surgery + suture adjustment if performed) and compared with the standard dose tables (based on preoperative distance esodeviation), as difference between dose performed and dose indicated by Parks's tables.

Methods: Participants reported vision correction habits, refractive error, screen time, mask wearing time, and dry eye symptoms since the COVID-19 pandemic onset through email survey.

Results: A total of 133 participants completed the survey.

Purpose: To report 8-year outcomes from a randomized controlled trial (RCT) comparing bilateral lateral rectus muscle recession (BLRc) with unilateral recession-resection (R&R) for childhood intermittent exotropia (IXT).

Design: Eight-year follow-up of RCT cohort.

Participants: Of 197 randomized participants, 123 agreed to continue follow-up after the 3-year outcome visit (baseline age, 3-< 11 years; basic-type IXT, 15-40 prism diopters [Δ] by prism and alternate cover test [PACT]; baseline stereoacuity, ≤ 400 arcsec; no prior surgery).

Significance: This pilot randomized trial, the first to evaluate a specific base-in relieving prism treatment strategy for childhood intermittent exotropia, did not support proceeding to a full-scale clinical trial. Defining and measuring prism adaptation in children with intermittent exotropia are challenging and need further study.

Purpose: This study aimed to determine whether to proceed to a full-scale trial of relieving base-in prism spectacles versus refractive correction alone for children with intermittent exotropia.

Importance: Lensectomy with primary intraocular lens (IOL) implantation is often used in the management of nontraumatic pediatric cataract, but long-term data evaluating the association of age and IOL location with the incidence of complications are limited.

Objective: To describe the incidence of complications and additional eye surgeries through 5 years following pediatric lensectomy with primary IOL implantation and association with age at surgery and IOL location.

Design, Setting, And Participants: This prospective cohort study used Pediatric Eye Disease Investigator Group cataract registry data from 61 institution- and community-based practices over 3 years (June 2012 to July 2015).

Visual discomfort and contact lens wear: A review.

Cont Lens Anterior Eye

August 2023

The Southern California College of Optometry at Marshall B Ketchum University, 2575 Yorba Linda Blvd, Fullerton, CA 92831, USA. Electronic address:

The purpose of this manuscript is to describe how vision influences contact lens discomfort and review the evidence supporting the hypothesis that contact lens discomfort can be caused by vision and vision-related disorders. Contact lens discomfort is a misunderstood and difficult to manage clinical condition. Most treatments and strategies aimed at alleviating discomfort focus on optimizing the contact lens fit and its relationship with the ocular surface, but these strategies commonly fail at relieving discomfort symptoms.

We evaluated the effect of part-time patching versus observation on distance exodeviation control in post hoc analyses of 3- to <11-year-olds with intermittent exotropia who were assigned to either patching 3 hours/day or observation in a previously reported randomized clinical trial. The present analysis was limited to a subgroup of 306 participants who at distance fixation spontaneously manifested either a constant or intermittent exotropia or had prolonged recovery after monocular occlusion (a distance control score of 2 or worse using the 0-5 Office Control Score scale) at baseline. We assessed change in control at distance and near fixation, from baseline to 3 months and baseline to 6 months (1 month after discontinuing patching).

Significance: When exploring relationships among clinical measures and patient-reported outcome measures in adults with convergence insufficiency, worse symptoms (Convergence Insufficiency Symptom Survey [CISS] score) seemed to be correlated with worse reading function domain score (Adult Strabismus-20 quality-of-life questionnaire). After treatment, improved symptoms were associated with improved reading function quality of life.

Purpose: This study aimed to explore relationships between clinical measures and patient-reported outcome measures in adults undergoing treatment for symptomatic convergence insufficiency.

Importance: Intravitreal bevacizumab effectively treats severe retinopathy of prematurity (ROP), but it enters the bloodstream and may reduce serum vascular endothelial growth factor (VEGF), potentially causing detrimental effects on developing organs in the premature infant.

Objective: To evaluate the association of intravitreal bevacizumab with plasma bevacizumab and VEGF concentrations at 2 and 4 weeks after predefined, de-escalating doses of intravitreal bevacizumab were administered to infants with severe ROP.

Design, Setting, And Participants: This phase 1 dose de-escalation case series study was conducted at 10 US hospitals of ophthalmology institutions from May 21, 2015, to May 7, 2019.
