What's New in Ocular rosacea

What's new in ocular rosacea

Rosacea is a common disease that causes inflammation of the skin and blood vessels of the face. There seem to be multiple factors, with the most obvious being photodamage over time. Other components include skin mites, generalized immune system inflammation, and skin irritation.

One of the most troublesome manifestations is eye involvement, ie ocular rosacea. This is seen in 58 to 72% of rosacea patients. This can result in gritty sensations in the eyes, “blurred vision, tearing, pain, and problems with glare.”

Treatment usually involves both dermatology and ophthalmology. For ocular rosacea, dermatology can mostly offer oral antibiotic pills to decrease inflammation over the entire face, including the eyes. Dermatology can also treat nearby inflamed skin, esp the nose and cheek regions.

Ophthalmology is usually in charge of medicated eye drops, partially because many common eye drops include corticosteroids that can increase intraocular pressures. Only ophthalmologists and eye clinics can screen for glaucoma development.

Patients almost always request information on non prescription options when possible. There is one study that showed that omega 3 fatty acids (dosage used was 500 mg capsules, each containing 325 mg EPA & 175 mg DHA, twice daily for 3 months) seem to “benefit the quality of the tear film.” Specifically, a study of 264 patients with dry eyes (not all patients had rosacea, but all had eye issues) found 66% of the treated group and 33% of the placebo group had improvement in eye symptoms. In addition, there was a significant increase in tear production, measured by Schirmer’s test & significant increase in tear retention, measured by tear breakup time.

No side effects were reported.

If you have rosacea or other skin issues, please make an appointment for dermatology consultation at (626) 251-1500 to discuss your options.
