While postoperative vision loss is often related to ischemic optic neuropathy, it is important not to overlook other causes, such as:
Central Retinal Artery Occlusion (CRAO): Caused by emboli or direct ocular compression, this condition leads to sudden monocular vision loss and requires immediate intervention.
Cortical Blindness: Occurs due to cerebral ischemia or hypoperfusion, often related to perioperative hypotension or emboli affecting the occipital cortex.
Giant Cell Arteritis (GCA): it is a vascular inflammatory condition often seen in older adults. It presents with sudden vision loss and requires prompt diagnosis and steroid treatment to prevent permanent blindness.
Acute Angle Closure Glaucoma: This can occur after surgery, leading to increased intraocular pressure and vision loss. Patients with predisposing risk factors should be identified preoperatively for monitoring and potential intervention.
Corneal Abrasion: Although less severe, corneal abrasions from intraoperative trauma can cause visual disturbances and should not be overlooked.
