A Pakistani expat living in Sharjah has fully regained his eyesight after doctors in Dubai performed emergency brain surgery to treat a rare and life-altering medical condition, hospital officials said. Emad Arif Khan, a 30-year-old real estate consultant, arrived at Aster Hospital Mankhool with sudden loss of vision in both eyes — a medical emergency later found to be caused by a large arachnoid cyst in his brain. Doctors said the cyst caused dangerously elevated intracranial pressure, compressing areas of the brain responsible for vision and placing the patient at risk of permanent blindness.

From flu recovery to sudden blindness

Two weeks before seeking urgent medical help, Khan had recovered from a flu. Shortly after, he developed pain during eye movement, persistent headaches and worsening blurred vision. Initially treated at another clinic with eye drops, his condition continued to deteriorate, making everyday tasks — including reading, writing and working — increasingly difficult. Concerned, he sought help from the ophthalmology department at Aster Hospital Mankhool. Swift diagnosis, life-changing surgery Dr. Parth Joshi, Specialist Ophthalmologist at Aster Hospital Mankhool, immediately identified papilledema, or swelling of the optic nerves, a red flag for dangerously high pressure in the brain. An urgent MRI scan revealed a large arachnoid cyst, along with a smaller cyst near the cerebellum. While arachnoid cysts are found in about 1.4 percent of patients undergoing brain MRI scans, more than 90 percent are asymptomatic and rarely require surgery. Cases causing sudden vision loss in adults are extremely rare. Recognising the severity of the case, the neurosurgery team led by Dr. Prakash Nair, Consultant Neurosurgeon, recommended immediate surgery. Dr. Nair performed surgery on the left side of the skull to open and drain the cyst, relieving pressure inside the brain. A biopsy later confirmed the cyst was benign. “Only a small percentage of arachnoid cyst patients require surgery, making this case exceptionally rare,” Dr. Nair said. “Swift diagnosis and immediate intervention were critical to saving Mr. Emad’s vision.” Following surgery, Khan experienced temporary speech difficulty: a known effect of brain pressure changes, but had no seizures or limb weakness. Repeat CT and MRI scans showed significant cyst reduction and full brain re-expansion, with no complications. By the time of his discharge on June 25, his headaches had resolved, vision had improved dramatically, and he was able to resume daily activities independently. Follow-up checks confirmed normal vision (6/6) and no neurological deficits. “When my vision loss occurred suddenly, it was a frightening experience for me and my family,” Khan said. “By the grace of Allah Almighty, I have completely recovered, and my vision has been fully restored.” “I am sincerely thankful to the doctors, nurses, and all staff at Aster Hospital Mankhool. From housekeeping to security, everyone showed professionalism, compassion, and constant care. They gave us confidence and peace of mind throughout this difficult journey.” Dr. Parth Joshi stressed the importance of early detection, saying: “Prompt recognition of papilledema and a multidisciplinary approach were key to achieving a positive outcome in this rare case.” Hospital officials said the case highlights the importance of seeking immediate medical attention for sudden vision changes and the role of coordinated care in preventing permanent disability.
