Near cue responses

The authors tested subjects with esotropia (13 constant esotropia, 16 fully accommodative esotropia and eight convergence excess) versus age-matched controls and 27 young adult emmetropes for response profiles in comparison to matched control groups. They found responses to the all-cue...

AC/A correlates

Three groups of subjects were included in this study. Group 1 had typically developing children from five to nine years with heterophoria less than 6PD. Group 2 had 19 children aged five to nine years with intermittent distance exotropia. Group...

Vision screening opinion

The aim of this paper is to describe experts’ perceptions of best practice guidelines and competency frameworks for visual screening in children. A focus group of approximately 75 minutes duration consisted of five orthoptists and two paediatric ophthalmologists with more...

AC/A non-linearity

This study investigated whether or not the response accommodative convergence to accommodation (AC/A) ratio in 30 visually normal subjects is linear with lens presentation order counterbalanced. Accommodative response was measured using the Shin Nippon SRW 500 infrared autorefractor. Accommodation was...

Reduced angle after BT for postop diplopia test

The authors undertook a retrospective study to evaluate the extent of reduced deviation after Botulinum toxin (BT) when used as a postoperative diplopia test. They evaluated effect in 39 patients: 32 exotropia and seven esotropia. The same BT dose was...

Angle of deviation and psychological impact

This questionnaire-based prospective study using the Psychological Impact Questionnaire was designed to investigate whether the size of the angle of deviation, age, sex, presence of diplopia, visual acuity of the worse eye and direction of deviation are related to psychological...

Childhood visual development in albinism and infantile nystagmus

The authors compare monocular and binocular development measures in 16 children with albinism, 10 with infantile nystagmus (INS) and 72 with normal vision to address interocular acuity differences, crowding ratios and binocular summation rates. The children were aged between four...

Strabismus detection by Plusoptix S08

In this study the authors evaluate the accuracy and sensitivity of the Plusoptix S08 photoscreener in detecting strabismus problems in 83 patients aged from six months to 40 years (mean 105 months). A pass was achieved for 25 patients and...

Gender variations in retinopathy

The Tromso Eye Study is a substudy of the Tromso Study; a population based longitudinal study based in Norway. The extensive 5869 participants had no diabetes and were aged between 30-87 years. Retinal images from both eyes were taken using...

Reduced blood flow and age-related macular degeneration

This was a prospective cross-sectional study assessing changes in blood flow velocity in patients with age-related macular degeneration (AMD) using a retinal function imager. Sixty eyes with wet AMD were compared to 53 control eyes and the average blood flow...

Complement factor B polymorphism and the phenotype of early age-related macular degeneration

The relationship between complement factor H (CFH) and age-related macular degeneration (AMD) is very well known, but other genetic polymorphisms relating to AMD are more poorly understood. This study was designed to investigate the relationship between complement factor B (CFB)...

The prevalence of macular cysts in patients with clinical cone-rod dystrophy determined by spectral domain optical coherence tomography

Cone-rod dystrophy is a progressive photoreceptor disorder which has multiple inheritance patterns. It is rare, with a prevalence of 1 in 40,000. Macular cysts are well recognised in other photoreceptor conditions such as retinitis pigments and choroideraemia, while they are...
