  • Cataracts: Cloudy areas on the eye's cornea interfering with vision.
  • Chalazion: Slow-growing swelling of the upper or lower eyelid usually caused by a blockage in the oil glands in the eyelid.
  • Choroiditis: Inflammation of the part of the eye called the choroid (layer behind the retina). Usually only one eye is affected.

  • Diabetic Eye Disease: Eye disease caused by diabetes
  • Diabetic Lens Osmosis: Eye lens vision changes due to diabetic sugars; usually reversible.
  • Diabetic Retinopathy: Diabetic retinopathy is the most common diabetic eye disease and a leading cause of blindness in American adults. It is caused by changes in the blood vessels of the retina.
  • Dichromasy: Defective colour vision
  • Double vision: Double vision
  • Dry Eye: Dry eyes or gritty eye feeling.
  • Eye and vision conditions: Medical conditions affecting the eyes or the vision systems.
  • Eye cancer: A malignancy that affects the eye
  • Eye foreign body: Feeling of grit or sand in the eye
  • Eye movement symptoms: Symptoms affecting the movement of the eye
  • Eye pain: Pain in the eye.
  • Fuchs' Dystrophy: Cataract-like vision problems from corneal deposits.
  • Glaucoma: Glaucoma is the term for a diverse group of eye diseases, all of which involve progressive damage to the optic nerve. Glaucoma is usually, but not always, accompanied by high intraocular (internal) fluid pressure. Optic nerve damage produces certain characteristic visual field defects in the individual's peripheral (side), as well as central, vision.
  • Halal Setton Wang syndrome: A very rare syndrome characterized mainly by eye, teeth, nail and skin abnormalities.
  • Head Conditions: Conditions that affect the head
  • Headache-free migraine: A syndrome with no headache but other migraine-like symptoms
  • Hemangioblastoma: A benign tumor that tends to occur in the central nervous system such as the brain and spinal cord. The tumor arises from the stem cells that develop into blood vessels or blood cells (hemangioblasts). Symptoms vary depending on the exact location and size of the tumor.
  • Hyperopia: Far-sightedness often requiring glasses
  • Hyphema: Bleeding between cornea and iris in the eye
  • Idiopathic basal ganglia calcification, childhood onset: A rare disorder involving the buildup of calcium deposits in various parts of the brain. It manifests as degeneration of the nervous system.
  • Iridocorneal Endothelial Syndrome: ICE syndrome is a spectrum of conditions of the eye, where the inner layer of the cornea appears abnormal. It includes Cogan-Reese syndrome, Chandler's syndrome, and progressive iris atrophy.
  • Iridocyclitis: Inflammation of the iris and ciliary body (just behind the iris) of the eye.
  • Juvenile idiopathic arthritis: A group of chronic inflammatory joint disorders that affects children. The condition generally involves periods of time where the condition is active followed by periods of abatement of symptoms. In some cases, the condition can be systemic and can cause symptoms such as fever and rash with organ involvement. There are three main types of juvenile idiopathic arthritis - oligoarticular, polyarticular and systemic (Still's disease).
  • Keratitis: Any inflammation of the cornea of the eye
  • Keratoconus: A rare degenerative eye disorder where the corneas of the eye become progressively thinner and cone-shaped which affects vision.
  • Lattice dystrophy: Cloudiness of the cornea
  • Leber's hereditary optic atrophy: Rare mitochondrial eye disease.
  • Lens disorders: Any disorder that affects the lens of ones eye
  • Macular hole: A hole in the eye's macula that affects the retina.
  • Map-dot-fingerprint dystrophy.: Eye cornea condition
  • Melanoma: Melanoma is the most dangerous type of skin cancer. It is the leading cause of death from skin disease. It involves cells called melanocytes, which produce a skin pigment called melanin. Melanin is responsible for skin and hair color.
  • Microcephaly -- microphthalmos -- blindness: A very rare syndrome characterized mainly by a small head, small eyes and blindness.
  • Myopia: Short-sightedness often requiring glasses
  • Neonatal ophthalmitis: Eye discharge in newborns
