H11.143

Clinical Causes: Vitamin A deficiency Dehydration Environmental factors such as dry, windy, or smoky environments Prolonged exposure to digital screens leading to decreased blinking Chronic conjunctivitis or other ocular surface diseases Autoimmune disorders affecting mucous membranes Use of certain medications that reduce tear production Aging-related changes in tear production Inadequate or irregular use of artificial tears or lubricating eye drops

Key Symptoms: Persistent dryness and grittiness in both eyes Redness and irritation of the conjunctiva A feeling of burning or discomfort Sensitivity to light (photophobia) Blurry vision or fluctuating visual clarity Watery eyes as a response to irritation Rough or cobblestone appearance of the conjunctiva Possible sensation of a foreign body in the eye

Diagnosis Path: Diagnosis of conjunctival xerosis involves a comprehensive eye examination by an ophthalmologist or an optometrist. The clinician will assess the conjunctiva's appearance, look for signs of dryness, and evaluate tear production. Special tests such as Schirmer’s test may be performed to measure tear secretion. The patient's medical history, including nutritional status and environmental exposures, is also considered. In some cases, blood tests might be recommended to check for underlying deficiencies or autoimmune conditions.

Treatment Protocols: Management of conjunctival xerosis aims to relieve dryness, restore moisture, and address underlying causes. Typical treatments include: - Use of artificial tears or lubricating eye drops regularly - Addressing nutritional deficiencies, particularly vitamin A supplements if needed - Environmental modifications such as using humidifiers or protective eyewear - Avoiding irritants like smoky or windy conditions - Management of underlying health conditions, including autoimmune diseases - Ensuring adequate hydration - In severe cases, physicians may prescribe anti-inflammatory medications or recommend specialized therapies to promote healing Once diagnosed and treated appropriately, many individuals experience significant relief from symptoms and prevent complications such as corneal involvement or infections.
