Sharjah, UAE – What began as a frightening medical emergency for a 65-year-old engineer ended with a remarkable recovery, thanks to the rapid diagnosis and coordinated care of specialists at NMC Royal Hospital Sharjah, who were able to restore his sight after he suddenly lost vision in one eye.

The patient arrived at the hospital in distress after experiencing an abrupt loss of vision in his right eye. Concerned that the condition could be related to a stroke or a neurological disorder, the medical team immediately initiated urgent investigations.

He was first evaluated by Dr. Sherif Mohamed Hussien, Neurologist, who ordered an emergency CT scan to determine the underlying cause of the sudden vision loss. While the patient feared a neurological emergency, the scan revealed an unexpected and potentially dangerous condition, a severe sinus infection.

Recognising the urgency of the situation, the patient was promptly referred to Dr. Ricardo Persaud (FRCS), Consultant ENT Surgeon, for further evaluation. During the clinical assessment, doctors observed that although the patient’s eye reflexes remained normal, there was a subtle bulging of the right eye, which raised further concern.

A detailed nasal examination uncovered the root of the problem: large nasal polyps, non-cancerous growths inside the nasal passages, along with a fungal sinus infection that was predominantly affecting the right side. Further analysis revealed that the infected sinuses were located extremely close to the eye and the optic nerve, the critical nerve responsible for transmitting visual signals to the brain.

The inflammation and pressure caused by the infection had begun to compress the optic nerve, leading to the sudden loss of vision.

Emergency Surgery to Protect the Optic Nerve

Given the high risk of permanent vision loss, the medical team decided to proceed with urgent surgical intervention.

The patient underwent Functional Endoscopic Sinus Surgery (FESS), a minimally invasive procedure that allows surgeons to access and treat sinus disease through the nasal passages using a small endoscopic camera. During the procedure, surgeons carefully removed the infected tissue and cleared the obstructed sinus cavities.

While operating, doctors discovered that part of the thin bone separating the sinuses from the eye had already been partially eroded due to the infection, a sign of how advanced the condition had become. Fortunately, the infection had not yet spread directly into the eye, allowing the surgical team to relieve the pressure before irreversible damage occurred.

A Rapid and Remarkable Recovery

The patient began noticing improvement in his vision shortly after the surgery.

At his one-week follow-up appointment, nearly 80 percent of his vision had returned. Over the following weeks, his recovery continued steadily. By the four-week mark, his eyesight had been fully restored, and his sense of smell, which had also been affected by the sinus disease, had returned as well.

A Warning About Hidden Sinus Complications

Although sinus infections and nasal polyps are often considered routine conditions, this case highlights that in rare circumstances they can lead to serious and unexpected complications, including vision loss if left untreated.

Specialists at NMC Royal Hospital Sharjah emphasise that persistent sinus symptoms such as nasal blockage, facial pressure, headaches or changes in vision should never be ignored. Early diagnosis through proper medical evaluation and imaging can prevent complications and protect vital functions like eyesight.

The multidisciplinary team expressed satisfaction with the successful outcome, noting that the case demonstrates the importance of rapid diagnosis, collaboration between specialties, and timely surgical intervention.

The patient, who described the experience as deeply frightening, expressed heartfelt gratitude to the doctors, nurses and medical staff at NMC Royal Hospital Sharjah for their swift action and compassionate care.

“I was terrified when I suddenly lost my sight,” he said. “But the doctors acted quickly and explained everything clearly. Thanks to them, I can see again and I’m incredibly grateful.”
