pterygium

conjunctivitis

blepharitis

stye

1. glaucoma actually means:

Explanation:

Question 19

A stye (hordeolum) is an infection of the eyelid's sebaceous gland, often caused by Staphylococcus bacteria. Pterygium is a growth on the conjunctiva, conjunctivitis is eye membrane inflammation, and blepharitis is eyelid inflammation (not specific to sebaceous gland infection like a stye).

The term "glaucoma" has roots related to "glauc-" meaning gray or cloudy, and it involves vision issues like cloudy/gray vision, with the term's etymology also connecting to "waterfall" - like appearance of vision. "Swelling of blood" (hemorrhage - related), "watery tumor", or "tumor of black" don't match its meaning.
