Abstract Details

Purpose:

To compare the macular retinal thickness in amblyopic and sound eyes on optical coherence tomography (SD-OCT). To identify macular structural characteristics associated with amblyopia.

Setting:

There is some evidence to suggest that macular thickness is increased in anisometropic and strabismic amblyopic eyes, but remains to be controversial. Some studies using OCT revealed an increase on this parameter, but others have found no differences compared to healthy eyes. Studies regarding isometropic amblyopia have shown non-conclusive results.

Methods:

This prospective-pilot study included 15 children previously diagnosed with unilateral anisometropic amblyopia (n=11), unilateral strabismic amblyopia (n=2) and bilateral isometropic amblyopia (n=2). The mean age was 8,4±4,2 years old (66,7% male, 33,3% female), and the mean spherical error was +1,3±1,5 D. They were examined with spectral-domain optical tomography coherence (SD-OCT). Macular thickness was meassured and compared between amblyopic and sound eyes.

Results:

In total, 17 amblyopic eyes (11 anisometropic, 2 strabismic and 4 isometropic) and 13 healthy eyes were analysed. There was no significant relationship between macular thickness in amblyopic and sound eyes (p>0.005). Same results were observed in the anisometropic, isometropic and strabismic groups when compared individually.

Conclusions:

There were no significant differences between amblyopic and healthy eyes regarding macular thickness. However, further analysis should be done, including more study subjects in each group. Refractive error and best corrected visual acuity should be also included in future investigations.
