What medication is used to manage lens subluxation?

• A. Atropine
• B. Latanoprost
• C. Epinephrine
• D. Timolol

Answer: (B)

Managing lens subluxation focuses on protecting the optic nerve when secondary glaucoma can arise from the unstable lens. Latanoprost lowers intraocular pressure by increasing aqueous humor outflow through the uveoscleral pathway, making it an effective option for reducing pressure in eyes with secondary glaucoma due to lens subluxation. It’s typically dosed once daily and well tolerated, which adds to its practicality in this context. In this scenario, other medications are less ideal: atropine would dilate the pupil and relax the ciliary muscle, not helping with pressure control and potentially destabilizing the lens further. Epinephrine can complicate glaucoma by variable effects on intraocular pressure, and timolol lowers production of aqueous humor but may not be as potent or convenient as a prostaglandin analog for reducing IOP in lens-subluxation–related glaucoma.
