Abstract

Introduction

Age-related macular degeneration (AMD) is considered one of the leading causes of visual impairment and visual loss throughout the world and most of the vision loss in AMD is due to the development of choroidal neovascularization (CNV)

CNV associated subretinal, intraretinal fluid and PED are seen with OCT, but these devices don’t provide a direct visualization of neovascular network. Optical coherence tomography angiography (OCTA) is considered a novel, safe, non-invasive, and rapid imaging technique to evaluate the microvascular anatomy in the retina and choroid without the need for contrast agents. It employs motion contrast imaging to high-resolution volumetric blood flow information providing angiographic images in just seconds.

The Prevalence of subclinical CNV in fellow eyes of patients with unilateral CNV has been reported to be between 6.25–27%. Therefore, the assessment, follow-up, and early detection of CNV in these eyes is crucial to ensure superior visual outcomes
Aim
The aim of this study was to evaluate the macula of the fellow eyes of the patients with unilateral CNV secondary to AMD using optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA).
