Overview of Vision problems, such as blurred vision, double vision or loss of peripheral vision
Double vision is the perception of two images of a single object seen adjacent to each other (horizontally, vertically, or obliquely) or overlapping. Diplopia is the medical term for double vision. Polyplopia is the perception of three or more images of a single object overlapping each other.
Double vision is called "monocular" when the double image is perceived by an eye that is tested alone. In "binocular" double vision, each eye sees a single image when tested alone, but a double image is present when both eyes are open.
Home Remedies for Vision problems, such as blurred vision, double vision or loss of peripheral vision :
There are a number of simple home remedies for sore eyes. Here are a few of them:
Place a cold washcloth over your closed eyes two to three times a day for five minutes at a time to manage pain and swelling.
When to see doctor for Vision problems, such as blurred vision, double vision or loss of peripheral vision :
Changes in vision are expected and normal as we grow older, but if you experience sudden changes in vision, it?s a sign that something is amiss, and it?s time to schedule an appointment with an eye doctor. Sudden changes in vision, including blurriness, blind spots, halos around lights or dimness of vision are grounds to see an eye doctor.
Changes in vision can get worse over time if left untreated, causing permanent damage. Vision changes may be indicative of an eye condition such as:
- Cataracts, or a clouding of the eye?s lens.
- Glaucoma, or increased pressure in the eye.
- Diabetic retinopathy, a complication of diabetes that causes retinal bleeding.
- Macular degeneration, or loss of central vision, blurred vision (especially while reading), distorted vision (like seeing wavy lines) and colors appearing faded.
- Retinal detachment
- Dry eye
Treatment for the Vision problems, such as blurred vision, double vision or loss of peripheral vision
Once the underlying cause has been determined, treatment is tailored to the underlying condition.
For example, diplopia stemming from refractive errors (myopia, hyperopia, astigmatism) can be corrected with glasses or contact lenses. Dry eyes may be treated with artificial tears, anti-inflammatory drops, punctal plugs, warm compresses, and a variety of other treatments. Many corneal irregularities are treatable with medication, laser, or surgery. Cataracts are treated with surgery, and posterior capsule opacification (after cataract surgery) is treated with laser. Binocular diplopia is occasionally caused by vision-threatening or life-threatening conditions requiring urgent or emergent treatment. This is particularly the case with aneurysms, head trauma, stroke, and other neurologic conditions. Any onset of diplopia with accompanying neurologic symptoms such as headache, nausea, dizziness, loss of balance, etc., should be evaluated immediately.
In many cases, double vision may subside with treatment of the underlying disease.
Double vision produced by poor blood supply to the nerves in diabetes will often resolve over time as the blood sugar is brought under better control. If eye muscle movements are restricted due to scarring (such as chronic Graves' disease) or entrapment (as after traumatic orbital bone fracture), surgery of the muscles or surrounding tissue may correct the problem.
Convergence insufficiency, or inability to align the eyes when focusing on a near object, is a common benign cause of intermittent binocular diplopia when reading. It can improve with eye exercises (pencil pushups) or with use of prisms.
Often glasses with prisms can be worn to correct binocular diplopia. If the diplopia is expected to resolve, temporary prisms (Fresnel prisms) can be added to glasses and later removed when the eyes realign.
