Developmental problems, injury, or breakdown of any part of the eye can lead to changes in vision and vision loss. Each part of the eye turns light into images. If one or more parts of the eye are not working correctly, the light information our brain receives may change or not arrive. Damage to cells in the retina causes some of the most common eye diseases, including age-related macular degeneration, diabetic retinopathy, glaucoma, and inherited retinal diseases.
Scroll down the site to find your disease or condition. Then, you look for the treatment color. The treatment colors are magenta (red-blue), blue, cyan (blue-green), green, yellow (red-green), and red. I give the treatment colors a number. Magenta = 0, blue = 1, cyan = 2, green = 3, yellow = 4, and red = 5. Amblyopia (Lazy eye) would then be categorized as 06-00-1. Here, the last digit, the treatment color, is blue. The first two digits are the disease/condition group (Eye Diseases are 06). The next two digits (Amblyopia (Lazy eye) is 00) are the illness within the group, and the last digit (blue is 1) is the treatment color.
When you use the projector, click on your treatment color, and a large image of it will appear. Make the color cover the whole page and project it onto yourself. When you use the LED light bulb, you choose your color manually.
Lazy eye (amblyopia) is reduced vision in one eye caused by abnormal visual development early in life. The weaker — or lazy — eye often wanders inward or outward.
Amblyopia develops from birth up to seven years of age. It is the leading cause of decreased vision among children. Rarely, lazy eye affects both eyes.
A cataract develops when the lens in your eye, which is usually straightforward, becomes foggy.
Light passes through a clear lens behind the iris (the colored part of your eye) for your eye to see. The lens focuses the light so your brain and vision can work together to process information into a picture.
When a cataract clouds over the lens, your eye cannot focus light similarly. It leads to blurry vision or other vision loss (trouble seeing). Your vision change depends on the cataract’s location and size.
Charles Bonnet syndrome (CBS) is a disease in which visual hallucinations occur because of vision loss. CBS is not related to psychosis or dementia, and people with CBS are aware that their hallucinations are not real. The hallucinations people with CBS experience are described as simple or complex. Simple hallucinations include shapes and patterns, while complex images include people, vehicles, animals, and plants. Hallucination episodes can range from a few seconds to hours and may recur over several days to years.
The conjunctiva is a part of the eye that covers the white of the eye. Irritation or damage to this surface can lead to conjunctival disease.
The conjunctiva can be damaged by injury, infection, chemical irritation, allergic reactions, dry eye, and, rarely, cancers. Inflammation in the conjunctiva is known as conjunctivitis.
Inflammation may be caused by infection (such as trachoma) or by an auto-immune response in which the body attacks itself with the system that usually fights off infection.
Age can also lead to the conjunctiva becoming loose and developing folds.
Symptoms of conjunctival disease may include redness and irritation, discharge, swollen eyelids, a burning sensation, and pain.
Some conjunctival conditions can cause significant scarring.
The lacrimal system or apparatus is the anatomical system containing the ocular structures for tear production and drainage. Therefore, any disruption to tear production or drainage will result in lacrimal disorders, leading to acute or chronic eye discomfort.
Dry eye is one of the most common eye problems. As we age, the protective tear film on the eye’s surface diminishes, exposing the eye’s delicate tissues to the drying effects of air, wind, dust, and the sun.
Wet eyes are blockages within the lacrimal drainage system that can keep tears from draining into the nose, causing the tears to build upon the lower eyelid and spill over into the face.
Bacterial conjunctivitis is characterized by lid swelling, yellowish discharge, sometimes a scratchy feeling in the eye, and itching and mattering, especially in the mornings upon awakening.
Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision. Abnormally high pressure often causes this damage in your eye.
Glaucoma is one of the leading causes of blindness for people over the age of 60. It can occur at any age but is more common in older adults.
Vision loss due to glaucoma can’t be recovered. Therefore, it’s essential to have regular eye exams that include eye pressure measurements so a diagnosis can be made in its early stages and treated appropriately.
Microphthalmia is an eye abnormality that arises before birth. In this condition, one or both eyeballs are abnormally small. In some affected individuals, the eyeball may appear to be ultimately missing. However, even in these cases, some remaining eye tissue is generally present. Such severe microphthalmia should be distinguished from another condition, anophthalmia. When no eyeball forms at all. However, the terms anophthalmia and severe microphthalmia are often used interchangeably. Microphthalmia may or may not result in significant vision loss.
People with microphthalmia may also have a condition called coloboma. Colobomas are missing pieces of tissue in the eye’s structures. They may appear as notches or gaps in the iris, the colored part of the eye.
Uveitis is the name for a group of diseases that cause inflammation of the uvea. The middle layer of the eye contains most of the blood vessels.
These diseases can destroy eye tissue and even cause eye loss. People of all ages can have it. Symptoms may go away quickly or last for a long time.
People with immune system conditions like AIDS, rheumatoid arthritis, or ulcerative colitis may be more likely to have uveitis. Symptoms may include blurred vision, eye pain, redness, and light sensitivity.
Visual disturbance occurs when you experience a short spell of flashing or shimmering light in your sight. The symptoms usually last around twenty minutes before your view returns to normal. Usually, there is no headache during the visual disturbance.
