Blepharitis




Blepharitis is a common, chronic condition that involves inflammation of the eyelid margins (the edges of the eyelids where the eyelashes grow).


🔍 Causes of Blepharitis:


  • Bacterial infection (especially Staphylococcus)

  • Seborrheic dermatitis (a type of dandruff)

  • Meibomian gland dysfunction (oil glands in eyelids blocked)

⚠️ Symptoms:

  • Red, swollen eyelids

  • Itchy or burning eyes

  • Crusts or flakes at the base of the eyelashes

  • Watery or dry eyes

  • Eyelashes falling out or growing abnormally

  • Blurred vision (in severe cases)


🩺 Diagnosis:

Based on clinical examination of the eyelids and eyelashes

  • Slit-lamp exam may be used to assess inflammation and gland function


💊 Treatment:


Lid hygiene: Regular cleaning of eyelids using warm compresses and gentle scrubbing


Antibiotics: Topical (e.g., erythromycin or bacitracin) or oral (e.g., doxycycline) in bacterial cases


Steroid eye drops or ointments (short-term use only)


Artificial tears for dryness


Omega-3 supplements for meibomian gland support


✅ Prevention & Management:

  • Daily eyelid cleaning

  • Avoid using eye makeup during flare-ups

  • Manage underlying skin conditions (e.g., rosacea, dandruff)

  • Avoid touching or rubbing the eyes

MYOPIA

What is Myopia? Myopia (commonly called nearsightedness) is a vision condition where a person can see nearby objects clearly but distant objects appear blurry. What Causes Myopia? It usually occurs when: The eyeball is too long from front to back. The cornea (the clear front surface of the eye) is too curved. As a result, light rays focus in front of the retina, instead of directly on it. Symptoms of Myopia: Blurred vision when looking at distant objects. Squinting to see clearly. Eye strain or headaches (especially after focusing on distant objects). Difficulty seeing while driving, especially at night (night myopia). Risk Factors: Genetics : If one or both parents are myopic, the risk increases. Excessive near work : Prolonged reading, computer, or phone use. Lack of outdoor time: Spending less time in natural light, especially in childhood. Treatment and Management Corrective Lenses: Eyeglasses or contact lenses with minus (–) power lenses. Refractive Surgery: LASIK, PRK, SMILE – re...
