Understanding and Managing Dry Eye Syndrome

Dry eyes result from insufficient tear production, which normally consists of water, oils, mucus, and antibodies from the lacrimal glands. These tears maintain eye moisture and protect against infections. When tear production drops, symptoms like irritation, redness, blurred vision, and sensitivity to light can occur.

Causes of dry eyes
Various factors contribute to dry eye development, which can be short-term or chronic, based on the underlying cause.

• Environmental factors such as air conditioning, sunlight, smoke, and low humidity
• Hormonal fluctuations, especially in women
• Age-related changes
• Medical conditions like diabetes and Parkinson’s disease
• Damage to tear-producing glands
• Allergies
• Ocular surgeries like LASIK and cataract removal
• Autoimmune illnesses including lupus and rheumatoid arthritis
• Persistent eye inflammation
• Prolonged contact lens use
• Vitamin deficiencies or excessive vitamin intake

Treatment approaches for dry eyes
Effective options include artificial tears, ointments, surgical interventions, punctal occlusion, LipiFlow®, and cyclosporine medication. Cyclosporine, marketed as RESTASIS®, is a common prescription eye drop that enhances tear production.

RESTASIS® contains cyclosporine, which reduces inflammation in the eye, stimulating natural tear production. Chronic dry eye often stems from excess T cells that inhibit nerve signals to tear glands, decreasing lubrication. RESTASIS® works by limiting these T cells, thereby encouraging tear growth.

It’s important to note that results are gradual; users should apply RESTASIS® consistently for around 90 days for full benefits. Avoid mixing it with other eye drops unless advised by a healthcare professional. Always follow your doctor’s instructions and be aware of potential side effects, such as temporary burning sensations in the eyes during initial use.
