BackgroundAmblyopia, the most common visual impairment of childhood, is a public health concern. An extended period optical treatment before patching recommended by clinical guidelines several countries. The aim this study was to compare an intensive regimen, with and without (EOT), in randomised controlled trial.MethodsEuPatch trial conducted 30 hospitals UK, Greece, Austria, Germany, Switzerland. Children aged 3–8 years newly detected, untreated amblyopia (defined as interocular difference...
<h3>Aim</h3> This paper presents Convergence Insufficiency Symptom Survey (CISS) and orthoptic findings in a sample of typical young adults who considered themselves to have normal eyesight apart from weak spectacles. <h3>Methods</h3> The CISS questionnaire was administered, followed by full evaluation, 167 university undergraduate postgraduate students during the recruitment phase another study. primary criterion for this study that participants 'felt they had eyesight'. A score ≥21 used...
To describe different patterns of blinking in patients undergoing a visual field test and to establish whether the blink parameters are related threshold variability.Thirty-nine with diagnosed or suspected glaucoma were recruited undertake perimetric task twice. Blinks detected video eye-tracker system that records at sampling rate 60 Hz. Blink frequency, duration, episodes microsleep (eye closures >500 ms) analyzed, correlated test-retest variability. The timing blinks respect stimulus...
Background/aims To investigate the presence of asymmetrical accommodation in hyperopic anisometropic amblyopia. Methods Accommodation each eye and binocular vergence were measured simultaneously using a PlusoptiX SO4 photorefractor 26 children aged 4–8 years with amblyopia 13 controls (group age-matched) while they viewed detailed target moving depth. Results Without spectacles, only 5 (19%) anisometropes demonstrated symmetrical (within 95% CI mean gain sound group), whereas 21 (81%)...
BackgroundAlthough eye exercises appear to help heterophoria, convergence insufficiency, and intermittent strabismus, results can be confounded by placebo, practice, encouragement effects. This study assessed objective changes in vergence accommodation responses naive young adults after a 2-week period of under controlled conditions determine the extent which treatment effects occur over other factors.MethodsAsymptomatic were randomly assigned one two no-treatment (control) groups or six...
Abstract Purpose The relative efficiency of different eye exercise regimes is unclear, and in particular the influences practice, placebo amount effort required are rarely considered. This study measured conventional clinical measures following typical young adults. Methods A total 156 asymptomatic adults were directed to carry out exercises three times daily for 2 weeks. Exercises at improving blur responses (accommodation), disparity (convergence), both a naturalistic relationship,...
Purpose: This study investigated whether vergence and accommodation development in preterm infants is preprogrammed or driven by experience. Methods: Thirty-two healthy infants, born at mean 34 weeks gestation (range, 31.2–36 weeks), were compared with 45 full-term (mean 40.0 weeks) over a 6-month period, starting 4 to 6 postnatally. Simultaneous convergence detailed target measured using Plusoptix PowerRefII infrared photorefractor as moved between 0.33 2 m. Stimulus/response gains...
Aim: To provide an overview of the factors that might influence success or failure anisometropic amblyopia treatment.Methods: A literature-based review was conducted using mainly Science Direct. Searches were restricted to English-based publications over past 10 years, focusing on children before they reach visual maturation.Results: The most common considered within literature are patient age, degree anisometropia, depth amblyopia, and type treatment its compliance. However, methodological...
Aim: To compare the effect of induced vertical diplopia (small and large separation) on reading speed accuracy.Method: The Radner Reading Chart (RRC) was used to measure (correct words per minute (wpm)) accuracy (percentage). Accuracy measured using two different methods: 'accuracy-omission' where only omission a word reduced score, 'accuracy-addition omission' any error score. Three viewing conditions were created Fresnel prisms plano glasses: control condition without (6 prism dioptres (Δ)...
Aim: To determine whether horizontal fusional vergences are comparable when measured using a prism bar and synoptophore. Methods: Thirty two participants (18–23 years) had their blur, break, recovery points for convergence divergence amplitudes (6 m) All VA of 0.1 LogMAR or better in either eye, were heterophoric orthophoric binocular single vision. The target was 0.2 letter. synoptophore the foveal 'rabbit' fusion slides. placed over dominant eye testing speed seconds per dioptres (Δ),...
It is considered normal to have a small amount of superior rectus weakness in laevo and dextro elevation; however, there no documented definition for these parameters within healthy young adult population using ocular movement testing the synoptophore. The aim this study was collect normative data on degree underaction adults.Twenty-nine adults (3 males 26 females, mean age 20.30 ± 1.70 years) were recruited. Superior recti underactions inferior oblique overactions recorded during routine...
