While it is important to be on the lookout for common eye conditions such as glaucoma, cataracts, and macular degeneration, your eyes may also tell you when things are seriously off elsewhere.
1. High cholesterol
“Someone with high cholesterol can have transient vision loss that comes and goes, like a curtain or shade coming and going over their eye,” says Herrmann. This is a sign your carotid artery is plugged with plaque and struggling to get blood to your eye. You may also have eye pain, notice a grey ring around your cornea (called an arcus senilis), or have trouble adjusting to bright light. In some cases, yellowish cholesterol deposits called xanthelasma can show up on your eyelids or in the corners of your eye socket.
2. Thyroid problems
Your thyroid is a butterfly-shaped organ in your neck, and it controls certain hormones that help control your growth and metabolism. If your thyroid isn’t functioning properly it can lead to a host of problems, which sometimes includes swollen eye muscles and congested eye sockets that cause your eyes to bulge out and look bigger than usual, says Herrmann. You might also have double vision.
Graves’ disease, an autoimmune disorder that affects your thyroid, can make your eyelids retract, which can also make your eyes look bigger than usual. If your eyelids retract enough that you can’t close your eye, you may develop dry eye, since your lids can’t keep moisture in.
Regular eye exams are a good idea for anyone, but it’s a must if you have diabetes or are at high risk for the disease. “Diabetes can make the macula—the part of the retina that controls your central vision—swell or retain fluid or fluid,” says Herrmann……..
