Which of the following is affected by the use of prostaglandins in eye drops?

1. Night vision

2. Eye pressure

3. Color perception

4. Distance vision

The correct answer is: Eye pressure

The correct choice regarding the effect of prostaglandins in eye drops is related to eye pressure. Prostaglandin analogs, commonly used in glaucoma treatment, work by increasing the outflow of aqueous humor from the eye, which effectively lowers intraocular pressure. This is crucial in managing glaucoma, as elevated eye pressure can lead to damage of the optic nerve and subsequent vision loss. While other answer options address different aspects of vision and eye function, they are not directly influenced by the use of prostaglandin drops. Night vision, color perception, and distance vision may be affected by various ophthalmic conditions or treatments, but prostaglandins specifically target the reduction of eye pressure, making this the relevant choice.
