Infantile exotropia and developmental delay
This is a retrospective review of infants requiring surgery for infantile exotropia before the age of one year to report the surgical outcomes and frequency of associated developmental problems. The study reviewed 26 patients first assessed at two to 10...
A case report of bidirectional aberrant upward eye movement
The authors present a case report of a 14-year-old boy with left ptosis and strabismus since childhood. In primary position he had left hypotropia with ptosis. On elevation of the right eye, the left eye depresses and adducts. Conversely, on...
Horizontal angles in Brown’s syndrome
The purpose of this study was to determine the incidence of horizontal strabismus needing surgical management in Brown’s syndrome. This was a retrospective review of 19 eyes (eight right and 11 left) of 16 patients (seven male and nine female)....
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...Paediatric choroidal neovascular membrane secondary to optic disc drusen
Choroidal neovascular membrane (CNVM) is a rare cause of visual impairment in paediatric populations and predominantly affects individuals aged over 50. CNVM is defined as the pathologic growth of new abnormal blood vessels which extend from the choroid and break...
Case reports of neuro-ophthalmological complications of CIPD
The authors present three cases of neuro-ophthalmological complications of chronic inflammatory demyelinating polyradiculoneuropathy (CIPD). CIPD can lead to prominent nerve hypertrophy which can mimic other forms of neuropathy radiologically. In addition, complications can occur which can cause diagnostic difficulties. All...Ophthalmology for HCAs
The course explores the eye from basic anatomy & physiology to an overview of common conditions - chronic and acute and addresses some of the technical diagnostic aspects which are becoming more prevalent in modern ophthalmology. Delegates will also have...
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...
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....
