Patient with fixed dilated pupil, with iris atrophy and secondary glaucoma after penetrating keratoplasty is suggestive of.
**Core Concept**
Urrets Zavalia syndrome is a rare complication of ocular surgery, characterized by fixed dilated pupil, iris atrophy, and secondary glaucoma. This syndrome occurs due to ischemic damage to the iris and ciliary body following surgery.
**Why the Correct Answer is Right**
Urrets Zavalia syndrome is a direct result of ischemic damage to the iris and ciliary body during ocular surgery. The ischemia leads to iris atrophy, which in turn causes the pupil to become fixed and dilated. The ischemia also affects the trabecular meshwork, leading to secondary glaucoma. This syndrome is a well-documented complication of penetrating keratoplasty, among other ocular surgeries.
**Why Each Wrong Option is Incorrect**
**Option A:** Benedict's syndrome is a neurological disorder characterized by ataxia, oculomotor palsy, and internuclear ophthalmoplegia. It is not related to ocular surgery or ischemic damage to the iris and ciliary body.
**Option B:** Posner-Shlossman syndrome, also known as glaucomatocyclitic crisis, is a rare condition characterized by recurrent episodes of glaucoma and uveitis. It is not directly related to ocular surgery or ischemic damage to the iris and ciliary body.
**Option C:** Kaufmann's syndrome is not a recognized medical condition. It is possible that the question contains a distractor or an error.
**Clinical Pearl / High-Yield Fact**
Urrets Zavalia syndrome highlights the importance of meticulous surgical technique and careful patient monitoring during and after ocular surgery to prevent ischemic damage to the iris and ciliary body.
**Correct Answer:**
✓ Correct Answer: D. Urrets Zavalia syndrome
