Occlusion of sho posterior ciliary aeries may cause:
**Core Concept**
The posterior ciliary arteries are a group of branches that supply the posterior segment of the eye, including the choroid, retina, and ciliary body. Occlusion of these arteries can lead to ischemia and damage to the affected tissues.
**Why the Correct Answer is Right**
Occlusion of the short posterior ciliary arteries can cause choroidal ischemia, leading to a condition known as choroidal infarction. This can result in sudden vision loss, pain, and other symptoms. The short posterior ciliary arteries are responsible for supplying blood to the choroid, and their occlusion can have serious consequences for the posterior segment of the eye.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not directly related to the occlusion of short posterior ciliary arteries.
* **Option B:** This option may be related to other types of ocular ischemia, but it is not the most direct consequence of occluding the short posterior ciliary arteries.
* **Option C:** This option is not a known consequence of occluding the short posterior ciliary arteries.
**Clinical Pearl / High-Yield Fact**
The short posterior ciliary arteries are a common site of occlusion in conditions such as giant cell arteritis, and their occlusion can lead to severe vision loss if not promptly treated.
**Correct Answer: D. Choroidal infarction.**
