A man who came within hours of losing his sight is warning people not to dismiss tiny specks or threads floating across their vision, as they could indicate a serious condition. Eye floaters are something most people have encountered, particularly when looking at a bright sky or a white wall.
Understanding Eye Floaters
While they are frequently harmless and easily overlooked, floaters can sometimes require immediate medical attention. Formally termed muscae volitantes, Latin for 'flying flies,' floaters result from changes deep within the eye. The vitreous, the gel-like substance filling the eyeball, is perfectly clear at birth and completely attached to the retina. However, as individuals age, it progressively liquefies and begins to sag, forming clumps and strands that cast faint shadows on the retina, which appear as the floaters people observe.
Common Causes
Age represents the most common cause, while short-sightedness can accelerate the process. Prior eye surgery, including cataract removal, may also contribute, as can inflammation inside the eye and, in uncommon cases, bleeding into the vitreous stemming from conditions like diabetes.
When to Seek Immediate Help
For most individuals, floaters prove more of an irritation than a threat. However, certain situations demand immediate medical attention. A sudden surge of new floaters, flashing lights in peripheral vision, or the sensation of a grey curtain advancing across your field of view are all warning signs. These warning signs can indicate a retinal tear or detachment, which, without prompt treatment, may result in irreversible vision loss.
A Surgeon's Personal Experience
Mr Amir Hamid, a cataract and refractive surgeon with over 10,000 procedures to his name, understands this intimately. The Chief Medical Officer of eye hospital group Optegra unexpectedly found himself in the patient's position after developing the precise condition he has dedicated his professional life to treating. Mr Hamid required an emergency operation for a detached retina following the appearance of a blind spot in his right eye, a symptom he identified instantly.
"I was exercising when I noticed a black patch in my field of vision," he said. "Because I was a very high myope, very short-sighted, I knew immediately, being an eye doctor myself, that this was the sign of a retinal detachment."
Fortunately, he had a good contacts list and phoned Mr Chien Wong at OCL Vision, an excellent surgeon. He got to see him straight away the same day. "I'm a surgeon - I fix things. So my first thought was I need to find someone to fix this for me and who is the best guy to do it? My sight is really important to me. It's my livelihood, it's how I support my family."
Mr Chien Wong, Director and Partner at OCL Vision, who performed the procedure, revealed Mr Hamid had been mere hours away from losing his vision. "When another surgeon chooses me it means a lot," he said. "It's humbling and a privilege. Sight is such an important part of life but especially in a job like ours where people are putting their trust in you to carry out delicate and complex operations."
Empathy and Urgent Advice
The ordeal has also transformed how Mr Hamid relates to his own patients. He said: "It adds a level of insight and empathy. Patients find it reassuring that you can share a period in your life where you were vulnerable, just as they are. It has enriched me as a doctor."
He is now encouraging anybody who notices sudden alterations to their vision to act without delay. "Any situation where you have a rapid onset of visual impairment, you need to be seen immediately," he said. "Please don't be hesitant to seek that help straight away."
