Conjunctivitis is an inflammation of the conjunctivae, which are the mucous membranes covering the white of the eyes and the inner side of the eyelids. It usually affects both eyes at the same time although it may start in one eye and spread to the other after a day or two. It may be asymmetrical, affecting one eye more than the other. There are many causes and the treatment will depend upon the cause.
The macula is located in the center of the retina, the light-sensitive tissue at the back of the eye. The retina instantly converts light, or an image, into electrical impulses. The retina then sends these impulses, or nerve signals, to the brain.
The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain.
When the retina detaches, it is lifted or pulled from its normal position. If not promptly treated, retinal detachment can cause permanent vision loss.
Diabetic retinopathy is an eye disease that's associated with long-standing diabetes. It's a major cause of poor vision in the UK.Retinopathy can occur with all types of diabetes. If left untreated, diabetic retinopathy can lead to blindness.
Dry eye produces discomfort and reduces vision when the tear film becomes chronically table or unavailable thereby leading to dryness of the conjunctiva and cornea.
Severe problems with eyes should always be referred to a specialist, but alternative therapies can support orthodox treatment and may be very useful in conditions that affect the eyelids and tear glands.
