Post Traumatic Transient Cortical Blindness

Transient cortical blindness is a rare complication of mild head trauma, but it always creates fear in the patient and their family. However, it usually has a benign outcome. Post traumatic Transient Cortical Blindness is defined as temporary and complete visual loss associated with normal pupillary reflexes and fundoscopic examination with return of visual function without any long term neurological complications following minor head trauma. Since the number of reported cases are very less, transient blindness after head injury has been mostly attributed to hysteria if brain imaging and fundoscopy examination is normal. Post traumatic Transient Cortical Blindness was first reported by Lemiere [in 1918]but its pathophysiology is still unknown. We report one such case of transient blindness.

A pressing case of transient blindness

A 21-year-old male with chronic renal failure on dialysis was referred for emergency medical admission with sudden loss of vision. The symptoms, which started with bitemporal field loss, progressed within hours to complete loss of vision in both eyes. The admission blood pressure was 180/120. An emergency CT of the brain (Figure 1) was performed. The patient was treated for his raised blood pressure with intravenous labetelol and progressive return of the patients’ vision occurred over the ensuing 24 h. What findings are observed on the CT? What is the diagnosis? What other imaging techniques would help in the diagnosis?
