Kennedy p h enomeno n is seen in –
**Core Concept**
Kennedy's phenomenon is a clinical observation related to the management of glaucoma, specifically in patients undergoing trabeculectomy. It is characterized by a sudden increase in intraocular pressure (IOP) following the initial postoperative decrease, leading to potential vision loss if not promptly addressed.
**Why the Correct Answer is Right**
Kennedy's phenomenon occurs due to the formation of a synechial membrane between the iris and the trabeculectomy bleb, causing a blockage of aqueous humor outflow. This is a result of the anterior chamber's inflammatory response to the surgery, leading to the adhesion of the iris to the newly formed bleb. The subsequent increase in IOP can be attributed to the impaired aqueous outflow through the trabeculectomy site.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Kennedy's phenomenon is not related to the surgical technique of trabeculectomy itself, but rather a complication that can arise from it.
**Option B:** This option is incorrect because the phenomenon is not a result of the patient's preoperative glaucoma diagnosis, but rather a postoperative complication.
**Option C:** This option is incorrect because the phenomenon is not a result of the intraocular pressure being too low, but rather a sudden increase in IOP following an initial decrease.
**Clinical Pearl / High-Yield Fact**
To prevent Kennedy's phenomenon, it is essential to manage postoperative inflammation aggressively, using anti-inflammatory medications and ensuring proper wound healing.
**Correct Answer: A. Trabeculectomy.**
