Dark adaptometry
|
|
Dark adaptometryA type of electrophysiologic retinal testing done to measure the period of time which passes before the retina regains its maximal sensitivity to low amounts of light when going from conditions of bright light to darkness.
RELATED TERMS--------------------------------------
Electrophysiologic
Pertaining to electrophysiology.
Retinal
Light-absorbing portion of rhodopsin. The absorption of light causes retinal to change from 11-cis to 11-trans configuration
Retina
A membrane lining the inside of the back of the eye that contains light-sensitive nerve cells that convert focused light into nerve impulses, making vision possible.
Sensitivity
1. The reciprocal of the minimum stimulus strength required for the stimulus to be detected reliably (1/threshold) May be related to noise and other mechanisms. 2. Physiologically measured sensitivity averaged over many stimulus/response cycles. A measure of gain. Noise free.
SIMILAR TERMS--------------------------------------
Dark light
Rods spontaneously produce a signal that is indistinguishable from a photon elicited event even in complete darkness about once every 160 msec.
PREVIOUS AND NEXT TERMS--------------------------------------
Dander
Tiny scales shed from human or animal skin or hair. Dander floats in the air, settles on surfaces and makes up much household dust. Cat dander is a classic cause of allergic reactions.
Dandy fever
An acute mosquito- borne viral illness of sudden onset that usually follows a benign course with headache, fever, prostration, severe joint and muscle pain, swollen glands (lymphadenopathy) and rash.
Danlos syndrome
Better known today as Ehlers-Danlos syndrome (EDS), this is an inherited disorder with easy bruising, joint hypermobility (loose joints), skin laxity, and weakness of tissues. There are a number of different Ehlers-Danlos syndromes which share these features but can be categorized into nine different types.
Danon disease
A genetic disorder characterized by heart problems, mental retardation and muscle weakness that affects males who usually die of cardiac arrhythmia or heart failure at around the age of 30. The disease is due to a deficiency of LAMP-2 (which stands for lysosome-associated membrane protein 2.)
Darier disease
A genetic skin disease characterized by slowly progressive hardening of the skin (keratoses) around the hair follicles. This disorder is inherited in an autosomal dominant manner and is due to mutation in a gene called ATP2A2 on chromosome 12. Also known as keratosis follicularis.
Dark adaptometry
DASH diet
An eating plan designed to lower the blood pressure. DASH is an acronym for Dietary Approaches to Stop Hypertension. The DASH "combination diet" has been shown to decrease the blood pressure and so helps prevent and control high blood pressure. The DASH "combination diet" is rich in fruits, vegetables, and low fat dairy foods, and low in saturated and total fat. It also is low in cholesterol, high in dietary fiber, potassium, calcium, and magnesium, and moderately high in protein.
Date, expiration
The date for a drug estimated for its shelf life with proper storage in sealed containers away from harmful and variable factors like heat and humidity.
Daughter
1. A female offspring. 2. A female adopted child. 3. A product of radioactive decay. 4. A cell resulting from cell division.
Daw
Abbreviation meaning "dispense as written." One of a number of hallowed abbreviations of terms that have traditionally been used in prescriptions.
Day sight
Day sight (night blindness) is a classic symptom resulting from deficiency of vitamin A. Also called nocturnal amblyopia and nyctanopia.
