Ocular Cystinosis Experience in Southwestern Ontario.

Purpose: To evaluate ocular treatment adherence and its impact on clinical outcomes in patients with cystinosis in southwestern Ontario, where the disease incidence is higher due to a founder effect in the Old Order Amish population.

Methods: This was a retrospective case series of patients with ocular cystinosis seen at Victoria Hospital and the Ivey Eye Institute at St Joseph's Health Care in London, Ontario, Canada, from 2008 to 2023. The authors investigated the demographics, ocular manifestations, and visual outcomes and characteristics in pediatric patients with ocular cystinosis.

Management of Congenital Dacryocystocele: A Case Series and Literature Review.

Congenital dacryocystocele presents with a distinct bluish swelling in the medial canthal region in neonates. The authors present four illustrative cases with differing courses and a literature review on dacryocystocele management to raise awareness of the importance of prompt diagnosis, initiation of conservative management, and appropriate referral for surgical assessment. .

Effectiveness of pediatric Crawford tube implants when endoscopically assisted by ENT surgeons.

Objective: Epiphora in pediatrics is commonly treated with silicone nasolacrimal stents. The most common treatment duration is 3 months, but tubes are often unintentionally removed earlier and are still effective. There is no consensus on how long tubes need to be in situ and what factors influence treatment success.

mutation associated with severe myopia in a Canadian family.

Purpose: To describe a case of high myopia in a pediatric patient with a mutation in the gene and further characterize the diverse ocular phenotypes of heterozygous mutations.

Patient And Methods: We describe a three-year-old girl who presented at two months old with abnormal eye movements and suspected retinal dystrophy. Clinical exam and electroretinography (ERG) were conducted, and molecular next generation sequencing (NGS) with the Inherited Retinal Dystrophies panel was completed in our patient and offered to the family.

Successes and shortfalls of community Plusoptix photoscreening: results from the iSee study in Southwestern Ontario.

Objective: The purpose of this work is to provide the final results from a community-wide photoscreening program in Southwestern Ontario for children aged 18 to 72 months, and to estimate the prevalence of amblyogenic risk factors in this population.

Study Design: Prospective, multisite photoscreening program.

Participants: 5959 children aged 18-72 months were recruited and screened in Southwestern Ontario at 210 locations over a period of 3 years and 4 months.

Progressive Retinal Findings in Hemolytic Uremic Syndrome.

Ocular involvement in hemolytic uremic syndrome is rare and in most cases presents with retinal ischemia, hemorrhages, and neovascularization. The authors describe the progression of retinal involvement as a rare complication of typical hemolytic uremic syndrome in a 2-year-old boy. Progression of retinal findings were demonstrated with serial fundus photographs.

Alternating Hypotropia with Pseudoptosis: A New Phenotype of Congenital Cranial Dysinnervation Disorder.

Congenital cranial dysinnervation disorders, also known as CCDDs, are characterized by aberrant innervation to extraocular and facial muscles resulting in unusual forms of incomitant strabismus. Anomalous innervation to extraocular muscles can result in a wide variety of phenotypes causing various clinical conditions such as Duane syndrome, congenital fibrosis of the extraocular muscles, and Möbius syndrome. We report a case of bilateral dysinnervation disorder causing atypical ocular movements in both eyes as the patient changes fixation from one eye to the other and from right gaze to left gaze that fits with the wider diagnosis of CCDDs.

Community vision screening in preschoolers: initial experience using the Plusoptix S12C automated photoscreening camera.

Objective: Amblyopia is the leading cause of monocular vision impairment in children. Early intervention is critical to prevent permanent vision impairment. Preschool vision screening programs in Canada are limited.

Preoperative Factors Affecting Stereopsis after Surgical Alignment of Acquired Partially Accommodative Esotropia.

Background/aim: Despite successful ocular realignment, many strabismus patients never develop high levels of stereopsis. The purpose of this study was to determine preoperative factors that affect postoperative stereopsis in patients with acquired partially accommodative esotropia (APAET).

Methods: This was a retrospective chart review of patients who underwent successful surgery for APAET.

Congenital trochlear-oculomotor synkinesis.

Synkinesis of the extraocular muscles forms a subset of congenital ocular motility abnormalities termed congenital cranial dysinnervation disorders. Synkinesis most frequently involves the abducens or oculomotor nerves and rarely the trochlear nerve. Only 3 such patients have been described in the literature.

Quality of referrals to a pediatric ophthalmology practice in South Western Ontario.

Objective: The purpose of this study is to examine the referrals made to a pediatric ophthalmology practice in south Western Ontario. Timing of initiating a referral for children presenting with esotropia and the management offered prior to referral will be examined to identify room for improvement.

Methods: Retrospective chart review of 326 children diagnosed with esotropia with an age of onset <5 years.

Factors affecting postoperative stereopsis in acquired nonaccommodative esotropia.

Objective: To identify and examine factors that affect postoperative binocularity in children diagnosed with acquired nonaccommodative esotropia (ANAET).

Design: Retrospective chart review.

Participants: Thirty-four pediatric patients who received surgery for ANAET by 1 surgeon (I.

Hypertropia following Spontaneous Resolution of Brown's Syndrome.

Purpose: To report a case of bilateral Brown's syndrome with unilateral spontaneous resolution causing hypertropia and significant head tilt.

Case Report: A 3 ½-year-old girl presented with bilateral typical Brown's syndrome and orthophoria in the primary position; she presented with unilateral resolution of right Brown's syndrome 6 months later, causing right hypertropia and gradually deteriorating left head tilt. She benefited from right superior rectus muscle recession to help correct her head posture.
