Optical Biometry Derived Axial Length Measurements Following Intravitreal Anti-Vascular Endothelial Growth Factor Treatment for Macular Edema.

Purpose: To evaluate axial length (AL) alterations in patients with macular disease over the course of intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment.

Methods: In this prospective, comparative study, 33 patients with macular edema underwent unilaterally intravitreal anti-VEGF therapy and were followed for two months; the contralateral eyes were considered as controls. Central retinal thickness (CRT) was measured with spectral-domain optical coherence tomography and AL with an IOL-Master optical biometer.
