Eyes Disorders |
 |
|
The eye is a complex structure
that receives and translates light into impulses that our
brain recognizes as images. Vision provides much of our
daily sensory input. It is important for us to be aware of
symptoms that indicate a potential threat to our vision. |

Disorders Symptoms |

There are many types of eye
problems and visual disturbances. These include blurred
vision, halos, blind spots, floaters, and other symptoms.
Changes in vision, blurriness, blind spots, halos around
lights, or dimness of vision should always be evaluated by a
medical professional. Such changes may represent an eye
disease, aging, eye injury, or a condition like diabetes
that affects many organs in your body. Vision changes and
problems can be caused by many different conditions:
Presbyopia difficulty focusing
on objects that are close. Common in the elderly. |
|
 |
Cataracts: Cloudiness over the eye's lens, causing poor
nighttime vision, halos around lights, and sensitivity to
glare. Daytime vision is eventually affected. Common in the
elderly.
Glaucoma: Increased pressure
in the eye, causing poor night vision, blind spots, and loss
of vision to either side. A major cause of blindness.
Glaucoma can happen gradually or suddenly, if sudden, it's
a medical emergency. |

Diabetic retinopathy: This complication of diabetes can lead
to bleeding into the retina. Another common cause of
blindness.
Macular degeneration loss of central vision, blurred vision
(especially while reading), distorted vision (like seeing
wavy lines), and colors appearing faded. The most common
cause of blindness in people over age 60.
Floaters: Tiny particles drifting across the eye. Although
often brief and harmless, they may be a sign of retinal
detachment.
Retinal detachment: Symptoms include floaters, flashes of
light across your visual field, or a sensation of a shade or
curtain hanging on one side of your visual field.
Optic neuritis inflammation
of the optic nerve from infection or multiple sclerosis. You
may have pain when you move your eye or touch it through the
eyelid. |
