Treatment of choice in acute congestive glaucoma –
**Core Concept**
Acute congestive glaucoma, also known as acute angle-closure glaucoma, is a medical emergency characterized by a sudden increase in intraocular pressure (IOP) due to blockage of the trabecular meshwork. The primary goal of treatment is to rapidly lower IOP to prevent optic nerve damage and preserve vision.
**Why the Correct Answer is Right**
The treatment of choice in acute congestive glaucoma involves administering topical or systemic medications to reduce IOP. Topical administration of beta-blockers, such as timolol, and carbonic anhydrase inhibitors, like acetazolamide, can help decrease aqueous humor production and increase its outflow. Systemic administration of carbonic anhydrase inhibitors is often used in combination with topical medications to achieve more rapid and significant IOP reduction. Additionally, oral beta-blockers like timolol or systemic alpha-2 agonists like brimonidine can also be used.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not specify the type of medication or the route of administration, making it a vague and non-specific choice.
**Option B:** This option is incorrect as it may not address the urgency of the situation and may not be effective in rapidly reducing IOP.
**Option C:** This option is incorrect as it does not take into account the potential need for systemic medications to rapidly lower IOP.
**Clinical Pearl / High-Yield Fact**
In cases of acute congestive glaucoma, it is essential to administer medications that can rapidly reduce IOP, as delays in treatment can lead to permanent vision loss. The combination of topical and systemic medications is often used to achieve more significant IOP reduction.
**Correct Answer:** C. Oral carbonic anhydrase inhibitors.
