Dry Eye Syndrome

Dry Eye Syndrome (DES) is a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film. It is accompanied by ocular symptoms such as irritation, redness, and visual disturbances resulting from tear film instability, hyperosmolarity, and inflammation of the ocular surface.

DES is primarily caused by tear deficiency (aqueous-deficient) or excessive evaporation (evaporative). Factors include Meibomian gland dysfunction (MGD), aging, hormonal changes (post-menopause), autoimmune conditions (Sjögren’s syndrome), environmental exposure (low humidity, wind), and prolonged digital device usage.

The core mechanism is tear hyperosmolarity, causing epithelial cell damage and apoptosis. This triggers a pro-inflammatory cascade, releasing cytokines into the tear film, which further destabilizes the lipid layer, leading to a vicious cycle of desiccation and chronic inflammation.

Global prevalence ranges from 5% to 50%. It is more common in women, older populations (>50 years), and those living in arid climates.

Age, female sex, contact lens wear, antihistamines/antidepressants, refractive surgery (LASIK), systemic autoimmune diseases, and air pollution.

A. Early Symptoms: Mild grittiness, intermittent blurred vision, slight burning.
B. Common Symptoms: Foreign body sensation, ocular fatigue, light sensitivity.
C. Advanced Symptoms: Constant pain, significant photophobia, stringy mucus discharge.
D. Emergency Symptoms: Sudden vision loss, severe eye pain, intense redness.

Blepharitis, reduced tear meniscus height, conjunctival injection, punctate epithelial erosions (PEE) on cornea, and debris in the tear film.

A. Clinical Assessment: Ocular Surface Disease Index (OSDI) questionnaire.
B. Laboratory Testing: Tear osmolarity, Matrix metalloproteinase-9 (MMP-9) testing.
C. Imaging Studies: Meibography.
D. Functional Tests: Schirmer’s test, Tear Break-Up Time (TBUT).
E. Biopsy Findings: Generally not indicated; rarely used for Sjögren’s confirmation.
F. Genetic Testing: Not standard.
G. Differential Diagnosis: Allergic conjunctivitis, blepharitis, chemical burns.

Test Name: Tear Osmolarity
Type: Tear Fluid Analysis
Purpose: Assess salt concentration
Expected Findings: >308 mOsm/L
Interpretation: Indicates hyperosmolarity/DED

Meibography: Uses infrared imaging to visualize Meibomian glands; detects gland atrophy and structural loss.

Allergic conjunctivitis (associated with itching/papillae), viral conjunctivitis (follicles/discharge), and epithelial basement membrane dystrophy.

Corneal abrasions, bacterial keratitis, permanent scarring, and reduced quality of life.

A. Lifestyle Modifications: Humidifier use, "20-20-20" rule, blink exercises.
B. Preventive Measures: Omega-3 supplementation, eyelid hygiene.
C. Medical Treatment:

• Lubricants: Artificial tears (preservative-free)


• Anti-inflammatories: Cyclosporine A, Lifitegrast


• Steroids: Loteprednol (short-term)

Generally manageable with chronic therapy. If untreated, risks include corneal ulceration and permanent vision loss.

Frequent breaks during screen time, protective eyewear in wind, and treating underlying systemic inflammatory diseases.
