Answer to Question 1

ANS: A, C, D, E
The inflow and outflow of aqueous humor controls the intraocular pressure. Glaucoma results when the pressure is chronically high. Muscles of the iris relax and constrict to control the amount of light entering the eye. Rods work in low light conditions. Cones work in bright light conditions.

Answer to Question 2

ANS: A
This is an Ishihara chart, which is used for assessing color vision. Depth and spatial perception are not typically assessed in a routine vision assessment. Visual acuity is usually tested with a Snellen chart.
