Eligibility

Inclusion criteria

Inclusion criteria: Patients diagnosed with amblyopia aged between 10 to 40 years and cooperative in the assessments of interocular suppression.

Exclusion criteria

Exclusion criteria: Amblyopic patients with strabismus associated with ocular albinism, diplopia, or a medical history of seizures are excluded.

Design outcomes

Primary

MeasureTime frame
Quantification of suppression size and depth in amblyopia using a newly developed clinical tool, measured in terms of the visual angle (degrees) over which suppression occurs and the contrast difference required to overcome suppressionTimepoint: 18 months—

Secondary

MeasureTime frame
To evaluate the association of suppression size (in terms of visual angle) and suppression depth (in terms of difference in contrast between amblyopic eye and fellow fixing eye) and visual acuity in individuals with aniso myopic and aniso hypermetropic amblyopiaTimepoint: 10 months—
