Questions: 13 Eyedrops are used to treat Multiple Choice presbyopia. macular degeneration. cataracts. glaucoma.

The answer is the fourth one (D): glaucoma.

Explanation for each option:

• Presbyopia: This is a condition associated with aging where the eye's lens loses its ability to focus on close objects. Eyedrops are not typically used to treat presbyopia; instead, corrective lenses or surgery are common treatments.
• Macular degeneration: This is a condition that affects the central part of the retina (the macula) and leads to vision loss. While there are treatments available, such as injections and laser therapy, eyedrops are not a primary treatment for macular degeneration.
• Cataracts: This condition involves the clouding of the eye's lens, leading to decreased vision. The primary treatment for cataracts is surgical removal of the cloudy lens, not eyedrops.
• Glaucoma: This is a group of eye conditions that damage the optic nerve, often due to high intraocular pressure. Eyedrops are commonly used to lower the pressure inside the eye and are a primary treatment for glaucoma.

Summary: Eyedrops are primarily used to treat glaucoma, making option D the correct answer.
