Ocular

Manifestations

of Systemic

Disease

Jacob J. Yunker, MD

Diseases and Surgery of the Retina, Macula &

Vitreous

Assistant Professor, Department of Ophthalmology

University of Kentucky College of Medicine

Objectives

1. To describe the ocular signs and symptoms associated

with selected systemic diseases and their serious ocular

sequelae.

2. To review the important features of diabetic retinopathy

and the current screening guidelines

3. To be familiar with the important ocular features of hypertension, thyroid disease, sarcoidosis and inflammatory conditions, malignancy and acquired immunodeficiency syndrome.

Introduction  “The eyes are the window to the soul.”
