Study Notes
Introduction to Ocular Pathologies
- Ocular pathologies encompass a wide range of eye diseases affecting structures from cornea and conjunctiva to retina and optic nerve.
- These conditions differ in cause, symptoms, and treatment.
Keratoconjunctivitis
- Keratoconjunctivitis is a general term for cornea and conjunctiva inflammation.
- Common symptoms include redness, irritation, swelling, discharge, and blurred vision.
- Diagnosis involves comprehensive eye exams, potentially including visual acuity testing, slit-lamp examination, and corneal topography.
- Treatment depends on the cause and can include topical anti-inflammatory drugs (corticosteroids, NSAIDs), lubricating eye drops, antibiotics, and allergy treatments.
- Underlying causes can be infections (bacterial, viral, fungal), allergic reactions, environmental irritants, dry eye syndrome, corneal abrasions, contact lens issues, or systemic conditions (like autoimmune disease).
Specific Keratoconjunctivitis Types
- Allergic Keratoconjunctivitis: Inflammation from allergic responses (e.g., pollen). Symptoms are intense itching, watery discharge, and redness.
- Viral Keratoconjunctivitis: Often due to viruses like adenovirus. Characteristic findings include conjunctival injection, preauricular lymphadenopathy, and significant irritation.
- Bacterial Keratoconjunctivitis: Caused by bacteria, marked by purulent discharge and considerable eye pain.
- Dry Eye Syndrome (Keratoconjunctivitis Sicca): Insufficient tear production causing corneal dryness and discomfort.
- Contact Lens-Related Keratoconjunctivitis: Stemming from poor lens hygiene, incorrect solutions, or lens material sensitivity. Symptoms often occur with contact lens wear.
Differential Diagnosis
- Distinguishing keratoconjunctivitis from other eye conditions necessitates analysis of discharge type (watery, mucous, purulent), symptom severity and duration, and patient history (exposure to irritants, contact lens use).
- Ruling out potentially more serious conditions like corneal ulcers/infections is critical.
Management and Prognosis
- Management focuses on treating the cause to relieve symptoms and avoid complications.
- Prognosis varies depending on the cause; most keratoconjunctivitis cases are treatable, and recovery is typical with proper management.
Importance of Prompt Diagnosis
- Prompt identification & treatment of keratoconjunctivitis are essential.
- Early intervention minimises symptom severity and prevents potential cornea complications, which may impair vision.
