Q

Desribe what you would see in saggital cut of eyelid

A

Bulbar conjunctiva on eyeball crosses coreanl epithelum where there is NO blood vessels, but lots of nerve endings

Concutiva then makes the Fornix (superioa dn inferior) that is a turnign point

Palpebral conjunctiva is then continous with Bulbar

pick up tears and Lacrimal Puncta

27
Q

Where do tears drain into ?

A

From Superior and Inferior Lacrimal Canalciuli –> pic up tears at lacrimal puncta -> Nasolacrial Duct in Nasolacrimal Canal –> Tears drain into Inferior Nasal Meatus
