Glossary for Astigmatism

  • Albinism: A rare inherited condition characterized by a lack of pigmentation in the hair, skin and/or eyes.
  • Anisometropia: This is where there is an inequality in refractive power of the two eyes
  • Arthritis -- short stature -- deafness: A very rare syndrome characterized by arthritis, short stature, deafness and numerous other abnormalities.
  • Atrophia aerata: A rare, inherited, slow progressing eye disease.
  • Bardet-Biedl Syndrome: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities.
  • Bardet-Biedl syndrome, type 1: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 1 is caused by a defect in chromosome 11q13.
  • Bardet-Biedl syndrome, type 10: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 10 is caused by a defect in chromosome 12q.
  • Bardet-Biedl syndrome, type 11: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 11 is caused by a defect in chromosome 9q33.1.
  • Bardet-Biedl syndrome, type 12: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 12 is caused by a defect in chromosome 4q27.
  • Bardet-Biedl syndrome, type 2: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 2 is caused by a defect in chromosome 16q21.
  • Bardet-Biedl syndrome, type 3: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 3 is caused by a defect in chromosome 3p12-q13.
  • Bardet-Biedl syndrome, type 4: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 4 is caused by a defect in chromosome 15q22.3.
  • Bardet-Biedl syndrome, type 5: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 5 is caused by a defect in chromosome 2q31.
  • Bardet-Biedl syndrome, type 6: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 6 is caused by a defect in chromosome 20p12.
  • Bardet-Biedl syndrome, type 7: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 7 is caused by a defect in chromosome 4q27.
  • Bardet-Biedl syndrome, type 8: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 8 is caused by a defect in chromosome 14q32.11.
  • Bardet-Biedl syndrome, type 9: A rare genetic disorder characterized by mental retardation, obesity, polydactyly and retinal pigmentation as well as other abnormalities. Type 9 is caused by a defect in chromosome 7p14.
  • Blepharoptosis -- aortic anomaly: A rare disorder characterized mainly by the presence of droopy upper eyelids and an abnormal aorta.
  • Blurred vision: Blurriness of vision or images.
  • Caudal appendage -- deafness: A very rare syndrome characterized mainly by deafness, finger bone abnormalities and a spinal extension giving a tail-like appearance (caudal appendage).
  • Cornea disorders: Disorders affecting the cornea of the eye
  • Diabetic Lens Osmosis: Eye lens vision changes due to diabetic sugars; usually reversible.
  • Ehlers-Danlos syndrome, cardiac valvular form: A rare genetic connective tissue disorder characterized by hypermobile joints, joint dislocations and skin hyperextensibility and fragility.
  • Eye and vision conditions: Medical conditions affecting the eyes or the vision systems.
  • Eye conditions: Any condition that affects the eyes
  • Fitzsimmons-McLachlan-Gilbert syndrome: A very rare syndrome characterized mainly by mental retardation paraplegia and thickened coarse skin on palms and soles.
  • Forsius-Eriksson syndrome: A rare inherited disorder characterized by reduced eye pigmentation and various eye problems. The disorder is inherited in a familial X-linked manner so only males manifest the symptoms whereas females may be asymptomatic or suffer mild symptoms.
  • Gorlin-Chaudhry-Moss Syndrome: A very rare inherited condition involving various physical and mental abnormalities.
  • Head Conditions: Conditions that affect the head
  • Hyperopia: Far-sightedness often requiring glasses
  • Joubert Syndrome 9: Joubert syndrome is a rare congenital neurological disorder characterized mainly by a brain anomaly where the cerebellar vermis is underdeveloped. This part of the brain is responsible to for balance and coordination. Most of the symptoms are of a neurological type. There are ten subtypes of the disorder, each with a different origin for the genetic anomaly. Type 9 is linked to a defect on chromosome 4p15.3.
  • Keratoconus: A rare degenerative eye disorder where the corneas of the eye become progressively thinner and cone-shaped which affects vision.
  • Kozlowski-Brown-Hardwick syndrome: A very rare syndrome characterized mainly by various skeletal anomalies, unusual facial appearance, eye abnormalities and communicating hydrocephaly.
  • Lens disorders: Any disorder that affects the lens of ones eye
  • Mental retardation -- short stature -- heart and skeletal anomalies: A very rare syndrome characterized mainly by mental retardation, short stature and heart and skeletal anomalies.
  • Microcephaly -- mental retardation -- retinopathy: A very rare syndrome characterized mainly by a small head, mental retardation and retinal disease.
  • Myopia: Short-sightedness often requiring glasses
  • Oculo skeletal renal syndrome: A very rare syndrome characterized mainly by eye, skeletal and kidney problems.
  • Presbyopia: Age-related far-sightedness often requiring glasses
  • Refractive Eye Disorders: Any disorder that affects the ability of the eye to focus on an object
  • Ring dermoid of cornea: A rare eye disorder which results in the appearance of a dark ring around the cornea.
  • Van Bogaert-Hozay syndrome: A rare disorder characterized by destruction of ends of finger bones, mental retardation, skin wasting and eye and facial abnormalities.
  • Vision distortion: Distortions or changes to vision
  • Volubilis, syndrome du: A rare birth defect of the optic papilla which is the part of the eye where the optic nerve emerges. Usually only one eye is affected.
