Lazy eye research
Did you wear glasses and an eye patch as a child? This study is investigating how visual information is combined and processed in a condition known as aniseikonia.
hen the two eyes see different size images it is known as aniseikonia. Aniseikonia occurs when you have a different prescription in each eye and is commonly found in people with amblyopia. Amblyopia, commonly known as ‘a lazy eye’ is a vision development disorder where one eye fails to reach normal vision and the vision cannot be improved with glasses. Amblyopia occurs in early childhood and is commonly caused by a misalignment/turn of one eye (strabismus/squint) or by a difference in prescriptions between the two eyes (anisometropia).
The study involves standard computer based vision tests and scans of the shape and structure of the eye to be taken. These tests will take about 3 hours in total and can be in one visit or across two visits at the University of Auckland Grafton Campus. In return you will receive a $20 MTA voucher.
We are looking for two groups of participants, ranging in age from 7 to 60 years old:
- Group 1: participants with amblyopia (lazy eye) due to a difference in the prescription between the two eyes (anisometropia)
- Group 2: participants who have a difference in prescription between the two eyes (anisometropia) but do not have amblyopia (lazy eye)
