Clinically in the non-injured eye, sympathetic ophthalmitis may manifest as:
**Core Concept**
Sympathetic ophthalmitis is a rare, bilateral granulomatous uveitis that occurs after a penetrating eye injury, often leading to inflammation in the uninjured eye. This condition is caused by an immune response to antigens released from the injured eye, leading to a systemic reaction.
**Why the Correct Answer is Right**
Sympathetic ophthalmitis can manifest in various forms in the uninjured eye, including acute plastic iridocyclitis, neuroretinitis, and choroiditis. The acute plastic iridocyclitis is characterized by inflammation of the iris and ciliary body, leading to a fibrinous exudate on the posterior surface of the iris. Neuroretinitis refers to inflammation of the retina and optic nerve, which can result in vision loss. Choroiditis is inflammation of the choroid layer, leading to granulomatous lesions and potential vision loss. These manifestations are due to the immune system's response to the antigens released from the injured eye.
**Why Each Wrong Option is Incorrect**
**Option A:** While acute plastic iridocyclitis is a manifestation of sympathetic ophthalmitis, it is not the only manifestation, so this option is incomplete.
**Option B:** Neuroretinitis is a correct manifestation, but again, this option does not encompass all possible manifestations.
**Option C:** Choroiditis is also a correct manifestation, but this option is incomplete, just like A and B.
**Clinical Pearl / High-Yield Fact**
It is essential to consider sympathetic ophthalmitis in the differential diagnosis of bilateral uveitis, especially in the context of a recent penetrating eye injury. Early recognition and treatment are crucial to prevent vision loss and other complications.
**✓ Correct Answer: D. All of the above**
