7. Causes Of Red Eye 1) Conjunctivitis. 2) Corneal Abrasions and Ulcer.
3) Acute Angle Closure Glaucoma.
4) Uveitis.
5) Episcleritis and Scleritis.
6) Sub-Conjunctival Haemorrhage.

8. Conjunctivitis
Follicles
Purulent discharge
Papillae
Redness
Chemosis

9. Acute Bacterial Conjunctivitis

10. Acute Viral Conjunctivitis

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

13. Corneal Ulcer Infection Bacterial: Viral: HSV, HZO Fungal:
Protozoan: Acanthamoeba in CL wearer
Mechanical or trauma
Chemical: Alkali injuries are worse than acid

14. Corneal ulcer stained green with fluorescein dye.

15. Purulent Corneal Ulcer with Hypopyon Excessive Steroid Usage

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

17. Acute Angle Closure Glaucoma

18. Uveitis Anterior: acute recurrent and chronic
Intermediate: Ciliary Body
Posterior: vitritis, retinal vasculitis, retinitis, choroiditis
Pan uveitis: anterior and posterior

19. Anterior uveitis (Iritis)
Photophobia, red eye, decreased vision, pain
Idiopathic. Commonest
Associated to systemic disease

of blood under conjunctiva. Asymptomatic
Idiopathic, trauma, cough, sneezing, aspirin, HT
Resolves within days
Treatment of Cause.
