Permanently impaired vision is a significant complication of untreated retinal detachment because the retina plays a crucial role in vision. When the retinal layers are separated, it can lead to the death of photoreceptors and other retinal cells if not promptly treated. The longer the retina remains detached, the greater the risk of irreversible damage, ultimately resulting in permanent vision loss. Early intervention is critical; therefore, timely diagnosis and treatment can help restore vision or prevent ongoing deterioration. The other options, while they can be related to different ocular conditions or complications, do not directly stem from untreated retinal detachment in the same manner as permanent vision impairment. For example, increased intraocular pressure, acute angle closure glaucoma, and non-functional pupil reflexes do not typically arise from retinal detachment itself but could emerge from other underlying eye diseases or conditions.
