OPHTHALMOLOGY & EYE DISORDERS
Ophthalmology is the branch of medicine that deals with eye health, eye diseases, and vision problems. Many common eye disorders can affect anyone and, if left untreated, may lead to serious complications including vision loss.
In this guide, we will understand two common eye disorders — Conjunctivitis and Glaucoma — including their causes, symptoms, types, and management strategies.
Conjunctivitis (Pink Eye):
What is Conjunctivitis?
Conjunctivitis is the inflammation of the conjunctiva — the thin layer covering the white part of the eye and inner eyelids. It causes redness and irritation, commonly known as “pink eye”.
Types of Conjunctivitis:
- Bacterial conjunctivitis
- Viral conjunctivitis
Causes:
- Viruses and bacteria
- Allergens (dust, pollen)
- Irritants (smoke, chemicals)
- Foreign particles
Symptoms:
- Redness and tearing
- Eye discharge
- Itching or burning
- Swollen eyelids
- Blurred vision
Management of Conjunctivitis:
Non-Pharmacological:
- Cold compresses
- Artificial tears
- Good hygiene practices
- Avoid rubbing eyes
Pharmacological Treatment:
- Antibiotic drops (bacterial)
- Antihistamines (allergic)
- Supportive care for viral cases
Maintaining hygiene is essential because conjunctivitis can be contagious.
Glaucoma:
What is Glaucoma?
Glaucoma is a group of eye disorders that damage the optic nerve, usually due to increased intraocular pressure. It is often called the “silent thief of sight” because it progresses without early symptoms.
Types of Glaucoma:
- Open-angle glaucoma
- Angle-closure glaucoma
- Secondary glaucoma
- Normal-tension glaucoma
- Pigmentary glaucoma
Symptoms:
Early stages may not show symptoms. As the disease progresses, symptoms may include eye pain, headache, blurred vision, halos around lights, and gradual vision loss.
Management of Glaucoma:
Non-Pharmacological / Surgical:
- Laser therapy
- Trabeculectomy surgery
- Procedures to improve fluid drainage
Pharmacological Treatment:
- Beta-blockers
- Prostaglandin analogues
- Alpha-2 agonists
- Carbonic anhydrase inhibitors
Glaucoma requires lifelong treatment and regular monitoring to prevent vision loss.
Summary:
Eye disorders like conjunctivitis and glaucoma require early diagnosis and proper treatment to prevent complications and preserve vision.
