Triple Vessel Coronary Artery Disease and Retinal Nerve Fibre Layer Thickness.

Dear Editor, Atherosclerosis is a pathological process that leads to blockage of the coronary artery and causes systemic vascular insufficiency. Coronary artery disease (CAD) is identified as a potential cause of insufficiency in optic nerve head (ONH) perfusion. Ischaemia due to vascular insufficiency in the ONH has been postulated as a potential cause of retinal nerve fibre layer (RNFL) damage.1 Structural damage to the RNFL may lead to the thinning of this important layer and cause functional impairment of the visual field. Early detection of RNFL damage is important in prevention of blindness due to many ocular diseases especially glaucoma. This study aimed to compare the RNFL thickness in patients with triple vessel coronary artery disease (3VCAD) with normal subjects.
