Brazilian best practice guidelines for amblyopia diagnosis and management

Area of Science:

• Ophthalmology
• Neuroscience
• Pediatric Medicine

Background:

• Amblyopia, or lazy eye, causes deficits in visual acuity, stereoacuity, and contrast sensitivity.
• Perceptual alterations, including motion perception changes, can affect the non-amblyopic eye.
• Neural plasticity in the amblyopic brain persists beyond early childhood.

Purpose of the Study:

• To propose evidence-based guidelines for amblyopia treatment and follow-up.
• To consolidate current understanding of amblyopia's perceptual consequences.
• To explore emerging treatment possibilities based on neural plasticity.

Main Methods:

• Review of existing studies on amblyopia treatment and outcomes.
• Analysis of perceptual deficits associated with amblyopia.
• Consideration of pharmacological and optical interventions.
• Evaluation of age-related treatment efficacy and discontinuation protocols.

Main Results:

• The gold standard treatment involves eyeglasses and patching the dominant eye.
• Treatment is most effective in children under 7 years old.
• Gradual discontinuation of patching over at least 5 weeks is recommended.
• Atropine penalization is an option for specific hyperopic cases.

Conclusions:

• Current guidelines focus on established treatments like patching and eyeglasses.
• The understanding of neural plasticity offers hope for novel amblyopia therapies in older individuals.
• Further research into post-critical period treatments is warranted.
