What is corneal abrasion?
Scratch to the surface of the cornea of the eye - can often happen secondary to acute red-eye due to patient scratching
What are the symptoms and signs of a corneal abrasion?
Sharp pain
Watering of eye

Topical antibiotics
+ treatment of red eye if thats caused the abrasion
What is Acute Anterior Uveitis?
Inflammation of iris and ciliary body
What are the signs and symptoms of Acute anterior uveitis?
Red, Pain, Watering
Photophobia
+/- Blurred vision, +/- Floaters
Cells in anterior chamber
Hypopyon
Small irregular pupil
May have previous history
In acute anterior uveitis, what causes “Cells in the anterior chamber”?
?
What is “Hypopyon”?
Leukocytic (inflammatory) exudate into the anterior chamber of the eye - will pool at bottom due to gravity
Caused by inflammation of the Uvea and Iris
How is acute anterior uveitis treated?
Topical steroids
Dilating drops
What scleritis?
Serious inflammatory disease that affects the Sclera - the white outer coating of the eye
Tends to develop secondary to autoimmune diseases - Rheumatoid arthritis etc

What is Acute Angle-closure glaucoma?
One of the types of Glaucoma in which the Iridocorneal angle is basically really fkn small/closed
Aqueous humor basically can’t flow properly and accumulates leading to an increase in pressure - eventually leading to problemos
What are the symptoms of Acute angle closure glaucoma?
Severe!!! pain
Redness
Blurred vision
Nausea & vomiting
What are the signs of acute angle closure glaucoma?
Hazy cornea
Fixed mid-dilated pupil
Hard eyeball
How is acute angle closure glaucoma treated?
Lower intra-ocular pressure
Constrict pupil
What is orbital cellulitis?
Infection of orbital tissues
most commonly caused by an acute spread of infection into the eye socket from either the adjacent sinuses or through the blood
