Summary
Binocular amblyopia treatment improved manual dexterity in children. Improvements were noted but did not fully normalize scores, with a weak correlation to visual acuity gains.
Area of Science:
- Ophthalmology
- Pediatric Medicine
- Neuroscience
Background:
- Amblyopia, or
- lazy eye
- is a developmental disorder affecting visual acuity.
- Manual dexterity deficits are frequently observed in children with amblyopia.
- The impact of amblyopia treatment on fine motor skills requires further investigation.
Purpose of the Study:
- To assess manual dexterity improvements in children with amblyopia following binocular treatment.
- To investigate the relationship between age at treatment, baseline sensory status, and manual dexterity gains.
- To determine if improvements in sensory status correlate with manual dexterity changes.
Main Methods:
- 134 children with amblyopia (younger and older groups) and 40 controls underwent assessments.
- Measurements included manual dexterity (Movement Assessment Battery for Children-2), visual acuity, fusion, suppression, and stereoacuity.
- Assessments were conducted at baseline and after 4-8 weeks of binocular amblyopia treatment.
Main Results:
- Amblyopic children exhibited significantly lower baseline manual dexterity scores than controls.
- Binocular treatment led to significant improvements in manual dexterity for both younger and older groups.
- Despite improvements, manual dexterity scores remained below control levels; gains weakly correlated with visual acuity improvement.
Conclusions:
- Manual dexterity impairments are prevalent in children with amblyopia.
- Binocular amblyopia treatment can enhance both visual acuity and manual dexterity.
- Further research is needed to understand factors influencing manual dexterity recovery.

01:28Angle Closure Glaucoma: Treatment
609
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:27Open Angle Glaucoma: Treatment
518
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
