Changes in endothelial morphology and ocular aberrations in pterygium

AIM: To compare changes in the corneal surface and endothelium, and to investigate their relationship with the horizontal length (HL), vertical length (VL), and depth of pterygium. METHODS: This study analyzed 34 eyes with unilateral primary pterygium and compared them to the 34 fellow eyes. Topographic values, wavefront aberrations, and specular microscopy findings were assessed. In addition, correlation analyses were conducted between the HLs and VLs, as well as the depth of pterygium. RESULTS: =0.013). CONCLUSION: The effect of pterygium on corneal aberrations is more strongly associated with its HL than with its VL. Depth do not affect aberrations, and pterygium has no significant effect on the ECD.
