Introduction
Autoimmune diseases have a variety of systemic manifestations; the eye is frequently involved in numerous autoimmune and rheumatologic disorders. Ocular manifestations are frequently nonspecific and different diseases may affect different parts of the eye, but early recognition of symptoms can help avoid or delay both systemic and ocular sequelae.
The most common autoimmune diseases that affect the eyes can be separated into four categories:
- Rheumatologic
- Dermatologic
- Endocrine
- Vascular
In this final part of our four-part series, we discuss giant cell arteritis, an autoimmune vascular disease that affects the eye.
