On admission, the patient reported vision blurring, pulsatile proptosis (with every heartbeat the eye would bulge out), and difficulty in conducting his day to day activities. He underwent a cerebral angiogram for better characterization of the condition, the statement said.

Based on the diagnosis by experts, the patient was found to have suffered from indirect CCF which is also known as cavernous dural arteriovenous fistula (it is the abnormal communication between the cavernous sinus and the dural arteries from the internal carotid artery and external carotid artery) which is an extremely rare neurological condition having a difficult course of treatment, it added.

Dr. Harsh Rastogi, senior consultant, Neuro Intervention Radiologist at Apollo Hospital said, "In this patient's case, his arterial blood was mixing with venous blood and as a reason, his eye was popping out with every heartbeat.

"For resolving the same, we conducted a surgery to disconnect the short-circuiting of the blood, leading to the complete resolution of the red-eye."

The hospital said their doctors could help the patient in restoring his visual activities in just five days from his admission to the completion of the surgery.

"The complexity of this case was to diagnose the right condition and provide aid. We are glad that the patient's post-operative recovery has been uneventful and he is back to his home contented and satisfied," read the statement.
