What is this?
Vacterial conjunctivitis

episcleritis
not serious, blood in potential space between the conjunctiva and sclera
spontaneous subconjunctival hemorrhage
What is this?
Subconjunctival hemorrhage
starts as pinguecula, solar elastotic degeneration of the conjunctiva, advances over the cornea, medical or surgical treatment

what is this?
Pterygium
