PURPOSE: Potential factors influencing stereopsis were investigated in patients with both refractive accommodative esotropia (RAE) and amblyopia. MATERIALS AND METHODS: A retrospective chart review was performed to find out all patients with the diagnosis of both RAE and amblyopia. Patients are classified into two groups: group 1 (with stereopsis) and group 2 (without stereopsis). Onset age of RAE, history of strabismus in family members, time of amblyopia treatment, mean spherical equivalent, anisometropia, ocular movement disorders, especially, overaction of inferior oblique (IO) muscle, visual acuity difference (VAD) between eyes, best-corrected visual acuity (BCVA) levels of amblyopic and normal eyes and the presence of alternation of fixation (AOF) were investigated as possible factors...

Purpose: A group of keratoconus subjects (KG) and a control group (CG) were evaluated for sensory and motor status. We tried to clarify the factors (best-corrected visual acuity [BCVA]), heterophorias, fusional amplitude, anisometropia, astigmatism) that may be associated with a binocular disturbance. Methods: BCVA (logMAR) was measured. Binocular vision was checked using cover tests, striate Maddox, and a 6Δ base-down prism (simultaneous perception), a prism bar (fusion and fusional convergence break point), and Titmus Fly Test (stereopsis)...

In this study, we investigated the effect of optical treatment on sensory eye balance in anisometropic amblyopia. Fourteen individuals (age: 13.7 ± 8.4 years old) with previously untreated anisometropic amblyopia were enrolled in the study. The average magnitude of their anisometropia (spherical equivalent) was 4.02 ± 1.19 DS. Their best corrected monocular visual acuity and sensory eye balance were measured before and after a 2-month period of full refractive correction (i.e., our optical treatment). Spectacle-corrected distance visual acuity (at 5 m) was measured monocularly using the Tumbling E Chart...

CLINICAL CASES: The cases are presented on 2 female patients with Straatsma syndrome, with satisfactory treatment of amblyopia. DISCUSSION: The level of anisometropia and myelination of retinal nerve fibres were different in these two patients. However, both achieved 0.20 (logMAR) visual acuity with correction in both eyes following amblyopia treatment with ocular patching. Visual prognosis of amblyopia associated with myelination of retinal nerve fibres and anisometropia is poorer than anisometropic amblyopia without myelination...

Purpose: Previous studies suggest that the adenosine receptor antagonist, 7-methylxanthine (7-MX), retards myopia progression. Our aim was to determine whether 7-MX alters the compensating refractive changes produced by defocus in rhesus monkeys. Methods: Starting at age 3 weeks, monkeys were reared with -3 diopter (D; n = 10; 7-MX -3D/pl) or +3D (n = 6; 7-MX +3D/pl) spectacles over their treated eyes and zero-powered lenses over their fellow eyes. In addition, they were given 100 mg/kg of 7-MX orally twice daily throughout the lens-rearing period (age 147 ± 4 days)...

PURPOSE: Optical treatment alone can improve visual acuity (VA) in children with amblyopia, thus clinical trials investigating additional amblyopia therapies (such as patching or videogames) for children require a preceding optical treatment phase. Emerging therapies for adult patients are entering clinical trials. It is unknown whether optical treatment is effective for adults with amblyopia and whether an optical correction phase is required for trials involving adults. METHODS: We examined participants who underwent optical treatment in the Binocular Treatment for Amblyopia using Videogames (BRAVO) clinical trial (ANZCTR ID: ACTRN12613001004752)...
