Objective The objective of this study was to evaluate the retinal nerve fiber layer thickness (RNFLT) and retinal macular thickness (RMT) in strabismic amblyopic patients. 

Methods Twenty-one patients diagnosed with strabismic amblyopia in the Department of Pediatrics at the Wenzhou Medical College Affiliated Eye Hospital were enrolled in the study. All the patients were esotropic. Their fellow eyes were normal and were used as the control eyes. Retinal nerve fiber layer thickness (RNFLT) and macular retinal thickness (MRT) were measured by optical coherence tomography (OCT).

Results The fovea and the central sector of the retina in amblyopic eyes were slightly but not significantly thicker than those in the normal fellow eyes.There was no significant difference in any section of retinal thickness between amblyopic eyes and fellow eyes (P>0.05). In addition, no significant differences in thickness were found between the retinal nerve fiber layers of amblyopic eyesand normal fellow eyes (P>0.05). 

Conclusion There were no differences in the fovea and the retinal nerve fiber layer thickness found between eyes with strabismic amblyopia and the normal fellow eyes.
