Which drugs are used to shrink the vitreous body and decrease intraocular pressure by drawing fluid out of tissues?

The option concerning hyperosmotic agents is indeed the most suitable choice for the question about drugs that shrink the vitreous body and decrease intraocular pressure by drawing fluid out of tissues. Hyperosmotic agents, such as mannitol or glycerin, work by creating an osmotic gradient. When administered, these agents pull water out of the ocular tissues and into the bloodstream, thus decreasing the volume of the vitreous body and lowering intraocular pressure. This mechanism is particularly useful in conditions like acute glaucoma or situations where rapid reduction of intraocular pressure is necessary.

Corticosteroids, while they have anti-inflammatory properties and can be used in the treatment of various ocular conditions, do not specifically function to draw fluid out of tissues or reduce intraocular pressure through osmosis. Beta-blockers are primarily used to reduce the production of aqueous humor, which can lower intraocular pressure but do not target the vitreous body directly in the manner described. Myotics, on the other hand, work by causing the pupil to constrict, which can aid in the drainage of aqueous humor but are not involved in shrinking the vitreous body or drawing out fluid from tissues. Hence, hyperosmotic agents are uniquely qualified for the role outlined in the question.
