Filter by:A randomized trial to determine whether simultaneous treatment with spectacles and patching has an equivalent VA outcome compared with sequential treatment, first with spectacles alone followed by patching (if needed), for previously untreated amblyopia in children 3 to <13 years of age.
Amblyopia and strabismus are characterized by a reduction in visual acuity, contrast sensitivity, grating acuity, vernier acuity, reading difficulties and binocular visual function deficits. Treated patients have residual visual function deficits. The purpose of the current study is to quantify various visual functions in amblyopic and strabismic participants at baseline, during and at the completion of treatment.
It aims to find the effectiveness and the safety of Virtual Reality (Caterna, DOBOSO, item code: SJ-VRS2018) to facilitate amblyopia treatment combining spectacles and occlusion. And it also aims to test whether amblyopia treatment outcomes with spectacles, occlusion and VR are significant better than those without VR, but with spectacles and occlusion. The experiment arm is designed to use the Caterna VR to treat amblyopia for total consistent 13 weeks, 3 times per week, while the control arm is not. Both arms are best optical correction and with patch the non-amblyopia eye 2 hours or 6 hours per day. All eyes are followed up for total 13 weeks.
The aim of this study is to quantify and compare the foveal avascular zone (FAZ), the parafoveal and foveal vessel density of superficial (SCP) and deep capillary plexus (DCP) and retinal thickness in deprivation amblyopic eyes, fellow non-amblyopic eyes, and age-matched normal eyes, using optical coherence tomography angiography (OCTA). The FAZ, parafoveal and foveal SCP and DCP, and retinal thickness were measured in normal controls and at least 3 months postoperatively in children with unilateral cataract and compared between groups after adjusting for axial length and spherical equivalents.
The purpose of this study is to investigate the effect of amblyopia therapy on cases who will receive Interactive Binocular Treatment (IBiTTM) without patching compared with those who will receive standard patching of the dominant eye with placebo IBiTTM. In this randomized clinical trial, 40 unilateral amblyopic children (3 to 10 years old) will be studied. All unilateral functional amblyopic children with best corrected visual acuity (BCVA) worse than 0.30 LogMAR at least in one eye or a difference of two BCVA lines of Snellen between the two eyes will be included and randomly will divide into the case (n=19) and control (n=21) groups. Cases will play I-BiT™ games, while controls will have standard patch therapy and will play with placebo IBiTTM for one month. All subjects will be underwent comprehensive ophthalmic examinations at baseline and at one-month follow-up.
Amblyopia affects 3% of the children and is caused by strabismus, anisometropia or both. Standard treatment is glasses and patching therapy. From North-America, behavioural training, i.e. dichoptic training, perceptual learning and video gaming, has become increasingly popular to improve visual acuity not only in children but also in adults. In this study we aim to compare the standard occlusion therapy with dichoptic video gaming.
Amblyopia, or lazy eye, is best defined by the American Academy of Ophthalmology as a unilateral or bilateral reduction of the best corrected visual acuity that occurs in the setting of an otherwise normal eye, or a structural abnormality involving the eye or visual pathway with reduction in visual acuity that cannot be attributed only to the effect of the structural abnormality. Which causes an abnormal visual experience early in life, with consequences such as deficiencies in the ability to perceive contrast and/or movement, visual acuity, accommodation and stereopsis. The treatment of choice consists in patching of the fellow eye 2 hours per day. The disadvantage of this treatment modality is that patients end up not complying and when treatment is interrupted, lazy eye reappears. Amblyopia was thought to be a monocular disease, now a days there are reports of cortical visual paths changes in both eyes (the fellow and amblyopia eye), believing that it might be a monocular consequence of a binocular disease. Following that statement new treatment studies have arisen, stimulating both eyes not only to improve visual acuity in the lazy eye, but to restore binocular function as well. These treatments use videogames in celular phones, computers, or tablets where the fellow eye is exposed to reduced contrast and the lazy eye is exposed to full-contrast. Although the evidence is promising, more studies are needed to establish effectivity and security of this treatment modality.

Purpose: of determining the role of Interactive Binocular Treatment (I-BiTTM) as a complementary method of patching in amblyopia therapy. Materials and Methods: In this randomized clinical trial study, 50 unilateral amblyopic children (25 male/25 female) less than 10 years with either best corrected visual acuity (BCVA) ≤0.3 LogMAR (Logarithm minimum angle of resolution) in amblyopic eye or difference of VA≥2 lines between two eyes will be included. Patients will be classified in the case and control groups (25 in each), randomly. Patching will be recommended in both, cases will also received I-BiTTM. The child will be asked to play I-BiTTM games through glasses with conjugate colored filters. Patching was continued for one month more in both groups. VA and stereoacuity were measured at baseline, one month at the end of I-BiTTM treatment and one month after I-BiTTM treatment.
