Postoperative vision loss is detected immediately postoperatively when patients report visual disturbances such as blurred vision or complete visual loss. Early recognition and intervention are important to enhance the prognosis.
Ophthalmic Consultation: When postoperative vision loss is suspected, an urgent evaluation by an ophthalmologist is needed. A thorough examination includes checking visual acuity, fundoscopic evaluation to identify optic nerve swelling or ischemia, and imaging such as MRI or CT to exclude other causes like stroke. Early intervention is critical, particularly in central retinal artery occlusion and acute angle closure glaucoma.
Steroid Administration: In conditions like giant cell arteritis, high-dose steroids should be administered immediately to prevent further visual damage. Even without confirmatory tests, initiation of corticosteroids can be vision-saving in suspected giant cell arteritis cases.
Blood Pressure and Hematocrit Management: Intraoperative and postoperative blood pressure must be carefully managed. Avoid prolonged hypotension and ensure optimal hematocrit levels to maintain adequate ocular perfusion. If a patient has significant blood loss during surgery, blood products or crystalloids should be used to restore blood volume and pressure.
Position Adjustments: For patients in a prone position, elevate the head by 10 degrees, which can reduce intraocular pressure and prevent postoperative vision loss. Careful positioning and using appropriate headrests (such as 3-pin holders) can minimize pressure on the globe and optic nerve.
