  5. Subconjunctival Haemorrhage • Diffuse or localised area of blood under conjunctiva. Asymptomatic • Idiopathic, trauma, cough, sneezing, aspirin, HT • Resolves within 10-14 days

  6. Dry Eye Syndrome • Poor quality • Meibomian gland disease,Acne rosacea • Lid related • Vitamin A deficiency • Poor quantity • Kerato Conjunctivitis Sicca • Sjogren Syndrome • Rheumatoid Arthritis • Lachrymal disease ie, Sarcoidosis • Paralytic ie, VII CN palsy

  7. Corneal Abrasion • Surface epithelium sloughed off. • Stains with fluorescein • Usually due to trauma • Pain, FB sensation,tearing, red eye

  8. Corneal Ulcer • Infection • Bacterial: Adnexal infection, lid malposition, dry eye, CL • Viral: HSV, HZO • Fungal: • Protozoan: Acanthamoeba in CL wearer • Mechanical or trauma • Chemical: Alkali injuries are worse than acid

  9. Episcleritis • Superficial • Idiopathic, collagen vascular disorder (RA) • Asymptomatic, mild pain • Self-limiting or topical treatment

  10. Scleritis • Deep • Idiopathic • Collagen vascular disease (RA,AS, SLE, Wegener, PAN) • Zoster • Sarcoidosis • Dull, deep pain wakes patient at night • Systemic treatment with NSAI or Prednisolone if severe

  11. Uveitis Anterior: acute recurrent and chronic Posterior: vitritis, retinal vasculitis, retinitis, choroiditis Panuveitis: anterior and posterior

  12. Anterior uveitis (iritis) • Photophobia, red eye, decreased vision • Idiopathic. Commonest • Associated to systemic disease • Seronegative arthropathies:AS, IBD, Psoriatic arthritis, Reiter’s • Autoimmune: Sarcoidosis, Behcets • Infection: Shingles, Toxoplasmosis, TB, Syphillis, HIV

  13. Ciliary flush Posterior synechiae Fibrin Flare Hypopyon KPs

  14. Acute Angle-closure Glaucoma • Symptoms • Pain, headache, nausea-vomiting • Redness, photophobia, • Reduced vision • Haloes around lights Ciliary hyperaemia Dilated pupil Corneal oedema
