Question 12

Another name for choroidal detachment. Definition

Answer 12

Effusion

Separation of choroid from sclera due to supraciliary space filling with serous or blood.

Question 13

Characteristics of a serous filled choroidal detachment

Answer 13

Clear 
Low IOP (4-6mm) 
Shallow AC (use cyclo to open) 
AC cells and flare 
No pain 
Will resolve as IOP increases, better outcome than hemorrhagic 

On B scan, looks dark

Yellow/brown 
High IOP
Worse outcome than serous 
Associated with pain bc high IOP
Redness, shallow AC, cells and flare
