What is not true about congenital glaucoma of eye?
**Core Concept**
Congenital glaucoma is a rare condition affecting infants and young children, characterized by increased intraocular pressure (IOP) due to impaired trabecular meshwork function. This leads to corneal edema, photophobia, and vision loss.
**Why the Correct Answer is Right**
Congenital glaucoma is often associated with anatomical abnormalities, such as trabecular dysgenesis or anterior chamber shallowening, which hinder aqueous humor drainage. The condition is usually bilateral, with symptoms appearing within the first year of life. **Option A**, which states that congenital glaucoma is typically unilateral, is incorrect because most cases are bilateral.
**Why Each Wrong Option is Incorrect**
**Option B:** This is incorrect because congenital glaucoma indeed presents with increased IOP, which is a hallmark of the condition.
**Option C:** This is incorrect because photophobia and corneal edema are common symptoms of congenital glaucoma.
**Option D:** This is incorrect because vision loss is a potential complication of untreated congenital glaucoma.
**Clinical Pearl / High-Yield Fact**
When evaluating a child with suspected congenital glaucoma, it's essential to assess the anterior chamber depth and look for signs of corneal edema, such as corneal thinning or Haab's striae.
**Correct Answer: A.**
