BACKGROUND: Previous studies show slow reading in strabismic amblyopia. We recently identified amblyopia, not strabismus, as the key factor in slow reading in children. No studies have focused on reading in amblyopic children without strabismus. We examined reading in anisometropic children and evaluated whether slow reading was associated with ocular motor dysfunction in children with amblyopia. METHODS: Anisometropic children (7-12 years) with or without amblyopia were compared to age-similar normal controls...

Cognition is very important in our daily life. However, amblyopia has abnormal visual cognition. Physiological changes of the brain during processes of cognition could be reflected with ERPs. So the purpose of this study was to investigate the speed and the capacity of resource allocation in visual cognitive processing in orientation discrimination task during monocular and binocular viewing conditions of amblyopia and normal control as well as the corresponding eyes of the two groups with ERPs. We also sought to investigate whether the speed and the capacity of resource allocation in visual cognitive processing vary with target stimuli at different spatial frequencies (3, 6 and 9 cpd) in amblyopia and normal control as well as between the corresponding eyes of the two groups...

Amblyopia is the most common cause of preventable blindness in children and young adults. Most of the amblyopic visual loss is reversible if detected and treated at appropriate time. It affects 1.0 to 5.0% of the general population. Various treatment modalities have been tried like refractive correction, patching (both full time and part time), penalization and pharmacological therapy. Refractive correction alone improves visual acuity in one third of patients with anisometropic amblyopia. Various drugs have also been tried of which carbidopa & levodopa have been popular...

BACKGROUND: Congenital cataract is one of the major causes of blindness and amblyopia in children. About one-third of the cases are inherited. CASE PRESENTATION: We applied whole exome sequencing for a pediatric patient with congenital cataract, small penis, baldness and absence of eyebrows and detected a compound heterozygous mutation in the lanosterol synthase (LSS) gene. These two mutations were inherited from the patient's parents. Both mutations altered the amino acid coding, at highly conserved amino acid residues...

Microperimetry (MP) is a technology that allows the study of retinal sensitivity at different foveal and parafoveal areas as well as eye fixation. It is a technique of functional evaluation, providing a direct correlation between anatomical and functional outcomes. There are a great variety of studies which evaluate the repeatability or reliability of measurements obtained with this technology and also describe and explore different clinical applications. MP has been shown to be useful in the characterization of sensory and motor conditions, such as amblyopia or nystagmus...

Amblyopia is a relatively common (incidence 3%) developmental disorder in which there is loss of vision as a consequence of a disruption to normal visual development. Although the deficit is monocular and known to be of cortical origin, the nature of the processing deficit is controversial. Human behavioral studies have identified two main deficits - a loss of contrast sensitivity and perceived spatial distortions. Here we use a multifocal fMRI approach to ascertain, in a group of anisometropic amblyopes, whether these two deficits have a single common cause or whether they are the result of two underlying independent cortical disorders...

Myasthenia gravis is a disorder of neuromuscular transmission that leads to fatigue of skeletal muscles and fluctuating weakness. Myasthenia that affects children can be classified into the following 3 forms: transient neonatal myasthenia, congenital myasthenic syndromes, and juvenile myasthenia gravis (JMG). JMG is an autoimmune disorder that has a tendency to affect the extraocular muscles, but can also affect all skeletal muscles leading to generalized weakness and fatigability. Respiratory muscles may be involved leading to respiratory failure requiring ventilator support...

A case of an autistic child, aged 8 years, who reported binocular diplopia following just 2 hours total occlusion per day for 6 weeks for strabismic/anisometropic amblyopia is reported. There was a history of known long-standing reduced uniocular acuity without treatment. Pretreatment Sbisa bar assessment suggested moderate suppression. The diplopia was treated over 6 months including occluding the amblyopic eye and gradually reducing the density of the occluder until fixation with the nonamblyopic eye could be maintained and diplopia ignored...

An upper lid eccrine hidrocystoma presenting as early childhood progressive ptosis is very rare. We present a 9-year-old female child with droopy right upper lid since birth and progressive increase in symptoms. She had right upper lid ptosis (marginal reflex distance 1 of -1 mm) with fair levator function (8 mm) and abnormal cystic change on the conjunctival side. Computerized tomography imaging delineated the well-defined cystic lesion with homogeneous cavity with no contrast enhancement. Following the cyst excision, a giant eccrine hidrocystoma measuring 25 mm × 15 mm was removed, the largest reported in pediatric eyes...

Kalpana Sharma, Praveen Panwar, Kulbhushan Prakash Chaudhary
Intermittent distance exotropia is a deviation characterized by an exophoria at near fixation and manifest exotropia at distance fixation. There is normal binocular fusional vergence and stereoacuity at near fixation, but the eyes tend to diverge in bright sunlight, tiredness, day dreaming and the patient may close one eye in such circumstances. Prematurity is associated with numerous eye pathology, besides retinopathy of prematurity, amblyopia, refractive errors, it is also associated with a higher risk esotropia and exotropia...
