Initial Signs and Symptoms

Visual deficits may occur during the resection, several hours after, or rarely on the second postoperative day as the patient awakens from a TURP-related coma.^[257] The range of initial signs and symptoms is wide, from complete loss of light perception to more subtle defects. The initial complaint may be visual halos and a blue visual hue.^[251] Dilated pupils that are unreactive to light, a normal IOP, normal extraocular muscle movement, and normal fundus examination without evidence of papilledema are the objective findings in these cases.^[251] These visual changes may resolve over a few hours or persist for up to 80 hours.^[257] Permanent visual loss has not been reported.
