| snow blindness | <ophthalmology> Severe photophobia that occurs secondary to ultraviolet light induced keratoconjunctivitis. (27 Sep 1997) |
|---|---|
| solar blindness | Damage to the fovea centralis of the retina and the adjacent choroid due to the thermal action of infrared rays, consequent to sungazing or watching a solar eclipse without sufficient eye protection. See: photoretinopathy. Synonym: eclipse blindness, solar blindness. (05 Mar 2000) |
| night blindness | Failure or imperfection of vision at night or in dim light, with good vision only on bright days. (12 Dec 1998) |
| note blindness | Loss of the ability to read music. (27 Sep 1997) |
| day blindness | <ophthalmology> Day blindness, defective vision in a bright light. Origin: Gr. Hemera = day, alaos = blind (18 Nov 1997) |
| object blindness | Visual agnosia for objects. The subjet sees the object, but cannot identify it; due to a lesion in area 18 of the occipital cortex. Synonym: object blindness, psychanopsia, psychic blindness. (05 Mar 2000) |
| taste blindness | Inability to appreciate gustatory stimuli. (05 Mar 2000) |
| text blindness | Loss of the ability to understand printed words or sentences (27 Sep 1997) |
| eclipse blindness | Damage to the fovea centralis of the retina and the adjacent choroid due to the thermal action of infrared rays, consequent to sungazing or watching a solar eclipse without sufficient eye protection. See: photoretinopathy. Synonym: eclipse blindness, solar blindness. (05 Mar 2000) |
| flash blindness | A temporary loss of vision produced when retinal light-sensitive pigments are bleached by light more intense than that to which the retina is physiologically adapted at that moment. (05 Mar 2000) |
| flight blindness | Visual blackout in aviators. See: amaurosis fugax. (05 Mar 2000) |
| legal blindness | Generally, visual acuity of less than 6/60 or 20/200 using Snellen test types, or visual field restriction to 20 |
| letter blindness | Visual agnosia for letters. The subject sees the letters but cannot identify them; caused by a lesion in the occipital cortex. (05 Mar 2000) |
| hearing loss, functional | Hearing loss without a physical basis. (12 Dec 1998) |
| orthodontic appliances, functional | Loose, usually removable intra-oral devices which alter the muscle forces against the teeth and craniofacial skeleton. These are dynamic appliances which depend on altered neuromuscular action to effect bony growth and occlusal development. They are usually used in mixed dentition to treat paediatric malocclusions.
