Endophthalmitis involves inflammation of all of the following, Except
**Core Concept**
Endophthalmitis is a severe inflammatory condition affecting the inner coats of the eye, specifically the vitreous and retina. It occurs due to an intraocular infection, often resulting from trauma, surgery, or endogenous spread from a systemic infection. The inflammation can lead to significant vision loss.
**Why the Correct Answer is Right**
The correct answer involves the exclusion of a structure not typically affected by endophthalmitis. The inner coats of the eye, including the vitreous and retina, are involved in the condition. However, the cornea, being a separate entity, is not directly affected by endophthalmitis, although it may be secondarily involved due to the spread of infection.
**Why Each Wrong Option is Incorrect**
* **Option A:** The sclera, being a tough, white outer layer of the eye, is not directly affected by endophthalmitis. However, it may be involved in the process of surgical intervention or as a result of the spread of infection.
* **Option B:** The choroid, a layer between the sclera and retina, is indeed affected by endophthalmitis due to the spread of infection.
* **Option C:** The retina, being a part of the inner coats, is directly involved in endophthalmitis, making it an incorrect option.
**Clinical Pearl / High-Yield Fact**
Endophthalmitis is a medical emergency requiring prompt treatment with intravitreal antibiotics and possibly vitrectomy surgery. Early recognition and management are crucial to prevent vision loss.
**Correct Answer:** C.
