**Core Concept**
Posterior capsule rupture is a serious complication of cataract surgery, which can lead to various intraocular and systemic complications. The posterior capsule is a thin membrane that covers the posterior chamber of the eye, and its rupture can expose the intraocular contents to the anterior chamber, leading to inflammation, infection, and vision loss.

**Why the Correct Answer is Right**
Posterior capsule rupture can lead to several complications, including:
* **Choroidal effusion**: a collection of fluid in the choroid layer of the eye, which can cause vision loss and increase intraocular pressure.
* **Retinal detachment**: a separation of the retina from the underlying retinal pigment epithelium, which can cause vision loss and require surgical intervention.
* **Endophthalmitis**: a severe inflammation of the interior of the eye, which can be caused by bacterial or fungal infection.
* **Cystoid macular edema**: a condition characterized by fluid accumulation in the macula, leading to vision loss.

**Why Each Wrong Option is Incorrect**
* **Option A:** Actually, posterior capsule rupture can lead to complications such as choroidal effusion, which is a known complication.
* **Option C:** Retinal detachment is a possible complication of posterior capsule rupture, making this option incorrect.
* **Option D:** Endophthalmitis is a known complication of posterior capsule rupture, making this option incorrect.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that posterior capsule rupture is a surgical emergency that requires prompt intervention to prevent further complications. The surgeon should immediately stop the surgery and consult with a retina specialist to manage the complications.

**Correct Answer:** B.
