The association of stroke with central and branch retinal arterial occlusion.

ABSTRACT:

Objectives

To determine the near-term risk of stroke following a retinal artery occlusion (RAO).

Methods

The risk of stroke was assessed in two manners; with a self-controlled case series (SCCS) and a propensity score (PS) matched cohort study using a US medical claims database. The date of RAO diagnosis was assigned as the index date. In the SCCS, incidence of stroke was compared in 30- and 7-day periods pre- and post-index date. In PS analysis, matched cohorts were created from patients with RAO or hip fracture. Cox proportional hazard regression assessed the hazard for stroke. Patients were censored at 1 year, upon leaving the insurance plan or if they had a qualifying event for the comparison group.

Results

The SCCS included 16,193 patients with RAO. The incidence
