Final answer:
The symptoms described (red eye, inflammation, pain, high IOP, reduced vision) are commonly associated with acute angle-closure glaucoma (D). Prompt medical attention is necessary to avoid permanent vision loss.
Step-by-step explanation:
The symptoms described (red eye, inflammation, pain, high IOP, reduced vision) are commonly associated with acute angle-closure glaucoma (D). Acute angle-closure glaucoma occurs when the drainage angle in the eye becomes blocked, leading to a sudden increase in intraocular pressure. This can cause severe eye pain, redness, blurred vision, and reduced vision. Prompt medical attention is necessary to avoid permanent vision loss.
