 ________ are light-sensitive cells in the retina that help to see color.

• Rod

• Cornea

• Cone

• Retina

Which diagnostic test measures tear production?

• STT

• Fluorescien staining

• Tonometer

• Direct ophthalmoscope

The sure diagnostic sign of corneal ulcer is

• Miosis

• Positive fluorescein test

• Blepharospasm

• Ciliary injection

Most of the thickness of cornea is formed by:

• Epithelial layer

• KCS

• Infective keratitis

• Uveitis

• Watering eyes

What form deep vascularization of the cornea?

• Long, branching corneal vessels (tree-like), originate in conjunctiva and cross over the limbus

• Nonbranching corneal vessels, straight circum-limbal vessels form a "brush border", appearing at the limbus

• Episcleral injection

• Conjunctival hyperemia

• Corneal neovascularization

• Hyphema

• All are correct

If only the ciliary body and the iris are inflamed it is called_______

• pan-uveitis

• anterior uveitis

• posterior uveitis

• Focal epithelial cell dysfunction

• Diffuse corneal edema

• Acute bullous keratopathy
