  Purpose
Retinal emboli is a common phenomenon in cardiac catheterization. In this study the investigators evaluate the incidence of retinal emboli post diagnostic and therapeutic cardiac catheterization over 300 patients. The incidence was 6.3% and had no clinical sequel on visual acuity and visual field.

Condition Intervention
Cardiac Catheterization Retina Embolism Procedure: diagnostic cardiac catheterization Procedure: therapeutic cardiac catheterization

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Clinical Significance of Retinal Emboli During Diagnostic and Therapeutic Cardiac Catheterization

Further study details as provided by Shiraz University of Medical Sciences:

Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: diagnostic cardiac catheterization
patients with diagnostic cardiac catheterization
Procedure: diagnostic cardiac catheterization
coronary intervention: angiography
Active Comparator: therapeutic cardiac catheterization
patient with angioplasty
Procedure: therapeutic cardiac catheterization
cardiac catheterization: angioplasty

Detailed Description:

Background and Purpose Cardiac catheterization may cause retinal embolization, a risk factor for cerebrovascular emboli and stroke. We describe the incidence of clinically silent and apparent retinal emboli following diagnostic and interventional coronary catheterization and associated risk factors.

Methods Three hundred selected patients attending a tertiary referral center for diagnostic and therapeutic cardiac catheterization were studied. Direct retinal examination and examination of the visual field and acuity were done before and after catheterization by a retinal specialist.
