Women at greater risk for autoimmune diseases with ocular manifestations

Do your own research physicians have less time

Communication with physicians managing the patient's systemic disease is crucial.

Women are as much as 50 times more likely to suffer from certain autoimmune diseases than men, and these diseases often have ocular manifestations that ophthalmologists should be aware of when examining their female patients, experts say.

"Autoimmune diseases are the No. 1 example of the higher risk" women carry for certain diseases due to sex, said Janine A. Smith, MD, of the National Eye Institute. "There are a lot of autoimmune diseases, and nearly every single one affects women more than men."

There is no definitively known reason for this disparity between the sexes, she said.

Dr. Smith said Sjogren's syndrome, with its symptoms of dry eye and dry mouth, is a prime example of an autoimmune disease seen more often in women. In addition, she said, systemic lupus erythematosus, rheumatoid arthritis and thyroid disease all disproportionately affect women, and all can have ophthalmic manifestations. continued below.

"The immune system between men and women is different," Dr. Smith explained. "Even the way men respond to viruses and women respond to infections, there are differences."

One theory, she said, is that because estrogens are naturally proinflammatory and androgens, specifically testosterone, are considered anti-inflammatory, women are more prone to developing autoimmune problems.

OSN spoke with Dr. Smith and other experts regarding the ocular complications of autoimmune disorders, what can be done to treat them and how to work with internal medicine specialists and others in management of patients with these diseases.


Systemic lupus erythematosus, a collagen vascular disease, affects women nine times as often as men. Typically young, middle-aged women are affected, said C. Stephen Foster, MD.

Lupus often causes dry eye, for which treatment is much like that for Sjogren's syndrome, but there are other possible ocular complications as well. Usually, Dr. Foster said, these complications are inflammatory.

"It might be something as relatively trivial as a rash, a low grade subtle dermatitis on the lid, or something that is directly relating to the eyeball itself with episodes of superficial inflammation," he said. "This superficial inflammation may be affecting only the conjunctiva or, more prominently, it will be episodic inflammation of the tissues deeper to the conjunctiva like the episclera or sclera."

Recurring episcleritis is a "trivial" but common ocular complication of lupus, Dr. Foster said. While it rarely requires aggressive therapy, episodes are often treated with corticosteroid drops, which can have long-term consequences, he explained.

"Eventually there is a price to pay, most particularly with respect to development to cataract," he said. "We believe taking an oral nonsteroidal anti-inflammatory medication is the most productive and appropriate way to address that."

Keratitis is another ocular manifestation of lupus. Patients can develop peripheral keratitis or multifocal superficial corneal inflammation, leaving small nebulae in the superficial cornea stroma.

"Both of them are associated with light sensitivity and photophobia. Both are important because they both carry with them a little more prognostic significance than does episcleritis or conjunctivitis," Dr. Foster explained. "Both are fairly disabling because of the photophobia."

He said, again, corticosteroids are usually used for treatment, but the long-term solution for keratitis is to address the underlying lupus with systemic medication.
