Severe ptosis in a new born should be operated at the age of:
**Core Concept**
Severe ptosis in a newborn is a condition where the eyelid droops significantly, potentially obstructing vision and causing other complications. The decision to operate on a newborn with severe ptosis involves considering the risk of surgery versus the benefits of correcting the condition early in life.
**Why the Correct Answer is Right**
The correct answer is based on the principle that early correction of severe ptosis in newborns can improve vision and reduce the risk of amblyopia (lazy eye). The **Bulbar Muscles**, including the levator palpebrae superioris, are still developing in newborns, making it a critical period for surgical intervention. **Blepharotomy** or **Blepharoplasty** can be performed to correct the ptosis, but the timing is crucial. In general, surgery is recommended between 3-6 months of age, when the risk of complications is lower and the benefits of early correction are more pronounced.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because surgery before 1-2 months of age may be associated with a higher risk of complications, such as **anesthesia risks** and **bleeding**.
* **Option B:** This option is incorrect because delaying surgery beyond 6-12 months of age may lead to **amblyopia** and **strabismus**, making it more challenging to achieve optimal outcomes.
**Clinical Pearl / High-Yield Fact**
The **6-month rule** is a general guideline for surgical correction of severe ptosis in newborns, balancing the risks of surgery with the benefits of early correction.
**Correct Answer: C. 6 months**
