A shutter that can snap shut and pull back thousands of times a day without losing its shape, the human eyelid is an engineering marvel of tension and release. We never consider our face’s structural integrity until it breaks in a way that doesn’t seem imaginable from a biological standpoint. That was a visceral and horrifying failure for a 39-year-old Brooklyn woman. She went into an ophthalmology clinic and said that her eyes had been wet and gritty for six weeks. This is a fairly frequent complaint in a city full of screens and dry air. Then she showed the real horror: her eyelids were flipping inside out and refusing to flip back, rolling up like a broken window shade.
After examining her, the physicians discovered that the tissue was not merely inflamed but had undergone a fundamental alteration. The upper lids were no longer stiff. The eyelid’s rigidity in a healthy eye is provided by the tarsal plate, a thick band of connective tissue that enables the eyelid to embrace the eyeball’s curvature. That plate had become pliable and stretchy in this patient. There was no snapping of her lid against the globe when the doctors drew it higher. With a painful ease, it continued to curl backward, revealing the raw, scarlet palpebral conjunctiva to the atmosphere.
With unusually direct medical terminology, the disorder is called Floppy Eyelid Syndrome (FES). The reality is a painful deterioration of the body’s connective fibers, despite the name being rather humorous. The eye dries out after being left uncovered and unblinking. It gets irritated. The cornea is left open to abrasions and ulcers in the absence of the windshield-wiper function of a taut eyelid. However, the most disturbing aspect of FES is not the eye’s condition but rather the reason behind it. The lungs are the cause, and the eye is frequently only the sufferer. +1

Following a line of data that has only become more conclusive in the past ten years, the Brooklyn doctors questioned the woman about her sleep. She acknowledged snoozing. Coffee couldn’t alleviate the bone-deep fatigue she had during the day. The fact that the damage was occurring in the dark was indicated by the fact that her eye symptoms were always worse in the morning.
She was referred for a sleep study, which validated the findings of the eyelid laxity. She suffered from obstructive sleep apnea. Her breathing halted, her airway collapsed, and her body was thrown into hypoxia twenty-seven times every hour. This is where the eyelid’s chemistry shifts in the oxygen-starved darkness.
Recent studies point to an exciting, horrifying series of occurrences. The body experiences oxidative stress when it is continually deprived of oxygen. Matrix metalloproteinases, which are particular enzymes made to break down proteins, are released as a result. These enzymes seem to target elastin, the protein that causes our tissues to snap and recoil, in patients with sleep apnea. The glue that holds the eyelid together is melted by the hypoxia.
After reading the first pathology report, I recall checking the suppleness of my own eyelid in the mirror and feeling a sudden, silent appreciation for the invisible tension that keeps us all together.
The mechanics exacerbate this chemical deterioration. Patients who have sleep apnea usually bury their faces in their pillows, toss and turn, and have restless sleep. The eyelid of a person with normal elastin can tolerate the friction of a pillowcase. However, the friction is too much for someone whose lids have gotten loose and rubbery. The cushion pulls on the loose skin. The eyelid everts. For hours, the patient grinds the fragile corneal surface against the linen while they sleep face down with their eye wide open and crushed against the mattress.
Because of the substantial correlation, ophthalmologists are increasingly being called upon to diagnose serious sleep problems. According to a study, almost all of the patients with FES had some form of sleep apnea. For the heart and lungs, the eye turns into a canary in the coal mine. The body is suffocating if the eyelids are malfunctioning.
The Brooklyn woman’s intervention did not involve surgery. The tarsal strip was not tightened with a scalpel on the eyelid, even though this is occasionally required in severe, long-term instances. Air was the prescription instead. She was connected with a continuous positive airway pressure (CPAP) machine, which maintains her airways open and pneumatic by continuously pumping oxygen into them.
The outcomes were nearly instantaneous.
After sleeping with the mask for two weeks, the change was finished. Her eyelids had regained their tightness, according to the specialists. They were no longer inverted. The tearing and the grit disappeared. The body stopped generating the enzymes that were destroying her elastin by addressing the hypoxia. The “rubber” reverted to solid tissue. She also said she was no longer sleepy during the day.
It serves as a clear reminder of how intertwined human biology is. We have a tendency to compartmentalize our illnesses; for example, an eye issue should be seen by an eye specialist, and a sleep issue by a sleep specialist. However, the body disregards these limits. A respiratory failure in the throat directly led to a structural breakdown in the face.
A diagnostic blind spot that still exists in contemporary medicine is brought to light by the “Floppy Eyelid” case. How many persons with persistently red eyes who are taking bottle after bottle of drops and who have been diagnosed with allergies or generic conjunctivitis are actually experiencing a blocked airway? The New York woman was lucky. Her symptoms were severe enough to warrant a closer examination.
Given the necessary resources, her recovery indicates that the body is remarkably forgiving. The tarsal plate’s deterioration was a biochemical reaction to stress rather than persistent scar tissue. The mechanism fixed itself as soon as the oxygen was restored. The shutters started operating once more. Finally, the eyes were able to close.
