BACKGROUND AND OBJECTIVE: To detect changes in the choroidal layer at the macular area in amblyopic eyes. PATIENTS AND METHODS: A cross-sectional study of 50 amblyopic patients (20 strabismic and 30 anisometropic) and 50 controls was done. Cross-sectional images using enhanced depth optical coherence tomography (OCT) were taken. Thicknesses were measured subfoveally and at 1,500 µm nasally, temporally, inferiorly, and superiorly. Submacular corresponding choroidal areas were also computed...

PURPOSE: Recent studies have found a choroidal thickening in amblyopic eyes and suggested that there might be a relationship between the choroid and amblyopia. The present study aimed to evaluate the effect of a six-month treatment of amblyopia on choroidal thickness in anisometropic hyperopic amblyopic children. METHODS: Thirty-two anisometropic hyperopic children with unilateral amblyopia were included in this prospective study. Subfoveal choroidal thickness was measured as the distance between the retinal pigment epithelium and the chorioscleral edge, by using spectral domain enhanced depth imaging optical coherence tomography...

BACKGROUND: Amblyopia is a common neurodevelopmental disorder of vision that is characterised by visual impairment in one eye and compromised binocular visual function. Existing evidence-based treatments for children include patching the nonamblyopic eye to encourage use of the amblyopic eye. Currently there are no widely accepted treatments available for adults with amblyopia. The aim of this trial is to assess the efficacy of a new binocular, videogame-based treatment for amblyopia in older children and adults...

Perceptual learning is considered a potential treatment for amblyopia even in adult patients who have progressed beyond the critical period of visual development because adult amblyopes retain sufficient visual plasticity. When perceptual learning is performed with the correction of high-order aberrations (HOAs), a greater degree of neural plasticity is present in normal adults and those with highly aberrated keratoconic eyes. Because amblyopic eyes show more severe HOAs than normal eyes, it is interesting to study the effects of HOA-corrected visual perceptual learning in amblyopia...

PURPOSE: Amblyopia is a leading cause of low vision and warrants timely management during childhood. We performed a literature review of the management of amblyopia and potential risk factors for amblyopia. METHODS: Literature review of the management of amblyopia and risk factors for amblyopia. RESULTS: Common amblyopia risk factors include anisometropic or high refractive error, strabismus, cataract, and ptosis. Often a conservative approach with spectacles is enough to prevent amblyopia...

PURPOSE: We aimed to examine the association between the 5-min Apgar score and reduced vision in children 3 to 6 years of age. METHODS: A total of 5834 preschool children aged 3 to 6 years participated in this school-based eye survey. Reduced vision was defined as unaided distance vision of 6/12 or worse in the better-seeing eye. The 5-min Apgar scores of the participants were retrieved from medical records. RESULTS: The overall prevalence of reduced vision in this population was 6...

Importance: Occlusion dose monitors have helped establish that better adherence to occlusion is associated with improved visual outcomes in patients undergoing amblyopia treatment. However, the role of adherence to glasses wearing is unknown. Objectives: To establish the feasibility and reliability of objectively monitoring adherence to glasses wearing using age-based norms, establish the association between adherence to glasses wearing and improvement in visual acuity (VA) after optical treatment and occlusion therapy, and analyze the effect of age, sex, refractive errors, type of amblyopia, and adherence to glasses wearing on improvement in VA...

PURPOSE: To compare the choroidal structure of the subfoveal area in the eyes of children with anisohypermetropic amblyopia to that of the fellow eyes and to age-matched controls using a binarization method of the images obtained by enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS: This study was performed at Nara Medical University Hospital, Tokushima University Hospital, and Kagoshima University Hospital, Japan. Forty amblyopic eyes with anisohypermetropic amblyopia and their fellow eyes (5...

BACKGROUND: We examined the effect of surgical repair on the pattern of refractive errors in Korean patients with congenital blepharoptosis. METHODS: We reviewed the clinical records of 54 patients with congenital blepharoptosis who attended our hospital from 2006 to 2012 and underwent a detailed refractive examination before and after ptosis repair surgery. Among them, 21 of the patients whose refractive data was available for both before and after the surgery were included in order to observe the effect of ptosis repair surgery on refractive error characteristics...

: Maturation of excitatory drive onto fast-spiking interneurons (FS INs) in the visual cortex has been implicated in the control of the timing of the critical period for ocular dominance plasticity. However, the mechanisms that regulate the strength of these synapses over cortical development are not understood. Here we use a mouse model to show that neuregulin (NRG) and the receptor tyrosine kinase erbB4 regulate the timing of the critical period. NRG1 enhanced the strength of excitatory synapses onto FS INs, which inhibited ocular dominance plasticity during the critical period but rescued plasticity in transgenics with hypoexcitable FS INs...

Purpose: Do humans with uncorrected anisometropia who have not developed anisometropic amblyopia exhibit a shift in ocular dominance nonetheless, reflecting a more subtle form of deprivation? Also, is such a change in dominance, if it occurs, permanent or could it be rectified by an extended period of optical correction? Methods: A total of 25 normal controls (27.5 ± 2.1 years; mean ± SD); 28 anisometropes (20.7 ± 5.6 years) who were fully corrected for more than 16 weeks prior to this investigation; and 24 anisometropes who had never been corrected (21...

OBJECTIVE: To assess the efficacy of Tocilizumab (TCZ) for Juvenile Idiopathic Arthritis (JIA)-associated uveitis. METHODS: Multicenter study of patients with JIA-associated uveitis refractory to conventional immunosuppressive drugs and anti-TNFα agents. RESULTS: We assessed 25 (21 women) patients (47 affected eyes); mean age 18.5±8.3 years. Uveitis was bilateral in 22. Cystoid macular edema (CME) was present in 9 patients. Ocular sequelae found at TCZ onset included: cataracts (13), glaucoma (7), synechiae (10), band keratopathy (12), maculopathy (9), and amblyopia (5)...

Current techniques for repairing large eyelid colobomas require preparation of other tissue sites and occasionally more than one procedure. We present a technique that requires only one procedure and is limited to the colobomatous eyelid; in addition, it is specifically designed to help avoid postoperative astigmatic and obstructive amblyopia. Outcomes are demonstrated in 3 cases of hemifacial microsomia. Large colobomas on the upper eyelid can be successfully and aesthetically repaired with only one procedure, incising only the congenitally abnormal eyelid...

Detecting the position of retinal structures, including the fovea center and macula, in retinal images plays a key role in diagnosing eye diseases such as optic nerve hypoplasia, amblyopia, diabetic retinopathy, and macular edema. However, current detection methods are unreliable for infants or certain ethnic populations. Thus, a methodology is proposed here that may be useful for infants and across ethnicities that automatically localizes the fovea center and segments the macula on digital fundus images. First, dark structures and bright artifacts are removed from the input image using preprocessing operations, and the resulting image is transformed to polar space...

Unicoronal craniosynostosis predisposes to ophthalmologic abnormalities such as strabismus, astigmatism, and amblyopia. The authors explored the ophthalmologic outcomes following fronto-orbital advancement (FOA). A systematic search of PubMed, Embase, and the Cochrane Library was conducted. Included studies reported postoperative rates of strabismus, astigmatism, and/or amblyopia. Two independent reviewers performed screening and extracted data including preoperative rates, laterality and severity of findings, need for ocular surgery, and timing of FOA...
