Management and outcomes of congenital fibrovascular pupillary membranes (CFPM)

Congenital fibrovascular pupillary membranes (CFPM) is defined as a white fibrous membrane across the pupil which may be an ectopic iris tissue arising from the aberrant migration of neural crest cells or a variant of persistent fetal vasculature. The authors...

Effects of ML4 on the eye

Mucolipidosis type IV (ML4) is an autosomal recessive lysosomal storage disease and is caused by variants of the MC0LN1 gene. It often presents in young individuals with eye and ocular adnexa issues. The authors present a case report and literature...

Risks to visual function from blepharokeratoconjunctivitis

This study evaluated the prevalence of blepharokeratoconjunctivitis (BKC) and prevalence of amblyopic risk factors with comparison of these rates to rates in the general US paediatric population. The authors evaluated the rate of patient reported symptoms in patients with and...

Simultaneous vs. alternate PCT disparity in XT

The authors quantified the relationship between simultaneous prism and cover test (SPCT) and alternate prism and cover test (APCT) alignment in patients with measures at the same visit after surgery for exotropia. This was a retrospective study of 955 patients...

Outcome of surgery for infantile exotropia after long-term follow-up of 4 years

The purpose of this study was to report long-term motor and sensory outcomes after unilateral lateral/medial rectus recession/resection (RR) in infantile constant exotropia. This was a retrospective review from 1995–2020 of 20 children (10 female, 10 male) with minimum 4-year...

Management of high AC/A esotropia

The purpose of this study was to determine the long-term effect of treating high accommodative convergence to accommodation (AC/A) esotropia with single vision lenses (SVL) compared with the effectiveness of using SVL on patients with basic refractive esotropia and a...

Choroidal thickness in strabismus and amblyopia

The authors examined the effect of exotropia, esotropia, anisometropic amblyopia and hypermetropia on choroidal thickness in a prospective cross section study. The study included 100 patients and 20 controls with a mean age of 8.5±2.9 years; 61 female and 59...

Results of single muscle advancement surgery

The aim of this study was to determine quantitatively the efficacy of medial and lateral rectus muscle advancement in consecutive exotropia and esotropia. The authors analysed the relationship between the change in muscle position and the change in visual angle...

Effective contrast ratio as a measure of binocular visual perception

The authors used a binocular phase combination paradigm to quantitatively evaluate and compare the binocular visual perception of normal individuals and patients with different types of strabismus to understand the binocular visual perception of patients with strabismus and evaluate whether...

Predictors for developing strabismus after paediatric cataract surgery

This study investigates the predictors for strabismus development in patients with paediatric cataract and their final visual acuity. The aim was to improve the treatment of both deprivation and strabismic amblyopia after surgery. The study included 46 children; 21 male,...

Reporting the development and pilot use of fixable surgical instruments

This study reports the development of instruments to substitute traction sutures during strabismus surgery and to act in place of surgical assistance. Three types of instruments were developed: (1) fixable multi-functional forceps; (2) fixable muscle hook; and (3) fixable retractor....

From monofocal to premium: Understanding the expanding landscape of intraocular lenses

For many years cataract surgery was framed almost entirely as a restorative procedure. The goal was straightforward: remove the cloudy lens and replace it with a clear one, restoring distance vision and allowing the patient to function comfortably with reading...
