Treatment of choice for congenital glaucoma:
**Core Concept**
Congenital glaucoma is a rare, but serious condition characterized by increased intraocular pressure (IOP) in infants and young children. It is often associated with anatomical abnormalities of the anterior segment, such as trabecular dysgenesis or anterior segment dysgenesis. The primary goal of treatment is to reduce IOP and prevent vision loss.
**Why the Correct Answer is Right**
The treatment of choice for congenital glaucoma is trabeculotomy with or without trabeculectomy. This surgical procedure involves creating a new pathway for aqueous humor drainage through the trabecular meshwork, thereby reducing IOP. In some cases, a secondary procedure such as trabeculectomy may be necessary to further reduce IOP. This approach has been shown to be effective in preventing vision loss and improving visual acuity in children with congenital glaucoma.
**Why Each Wrong Option is Incorrect**
**Option A:** **Medical therapy alone** is not sufficient to manage congenital glaucoma, as the underlying anatomical abnormalities cannot be corrected with medication.
**Option B:** **Cyclocryotherapy** is a procedure used to treat glaucoma by destroying the ciliary body, but it is not the treatment of choice for congenital glaucoma due to its potential complications and limited effectiveness in this population.
**Option C:** **Iridotomy** is a procedure used to treat angle-closure glaucoma by creating a new pathway for aqueous humor flow, but it is not effective in treating congenital glaucoma, which is often associated with open-angle glaucoma.
**Clinical Pearl / High-Yield Fact**
It is essential to diagnose and treat congenital glaucoma promptly, as delayed treatment can lead to permanent vision loss and long-term complications.
**Correct Answer: C. Trabeculotomy with or without trabeculectomy.**
