Huntington disease, King-Devick test, contrast sensitivity, eye movements, saccades
This study aimed to evaluate afferent and efferent visual function in Huntington’s disease (HD). HD is often portrayed by abnormal saccadic eye movements and afferent visual pathway involvement however these are poorly characterised and difficult to quantify at the bedside....
Age versus heterophoria and fusional vergence measures
This study aimed to establish the relationship between age, horizontal heterophoria, horizontal vergences, positive / negative fusional vergence and vergence facilities. The study recruited 112 subjects aged 39.8 ±14.97 years (range 18-65) of which 54.5% were female. There were 49...Comparison of two visual acuity test versions for different distances in a paediatric population
The authors present the findings of a study which aimed to determine whether using 2 metre and 4 metre retro-illuminated ETDRS charts are comparable in children. Order of testing was standardised (right eye, left eye, binocular), however different charts were...Prisms to treat AACE
Of 128 patients reviewed with binocular dysfunction, 30 (23.4%) had acute acquired concomitant esotropia (AACE). These patients complained of sudden onset diplopia at distance with no or moderate problems at near. There was no previous history of strabismus. Mean age...Detailed overview of diplopia causes and outcomes for a single tertiary care centre
