Which of the following is considered the standard of care for treating anterior uveitis?

The standard of care for treating anterior uveitis typically involves the use of cycloplegic agents to relieve pain and prevent posterior synechiae (adhesions between the iris and the lens). Among the options provided, homatropine is a common cycloplegic agent used for this purpose due to its effectiveness and relatively short duration of action compared to atropine.

Homatropine typically dilates the pupil and paralyzes the ciliary muscle, providing comfort to the patient by reducing ciliary spasm, which is often accompanied by anterior uveitis. While atropine can also be used and is effective as well, it has a longer duration of action and its use might be more associated with severe cases or specific patient situations.

In comparison, phenylephrine is primarily a mydriatic agent and does not paralyze accommodation effectively. Cyclopentolate is another cycloplegic but has a shorter duration than homatropine, making it less favorable in some chronic cases of anterior uveitis. Thus, homatropine's balance of efficacy and duration of action makes it a standard choice in clinical practice for this condition.
