Blind spot
The location where optic nerve fibers leave the retina. This area has no photoreceptors and therefore no visual input. The cortex appears to fill-in this missing information so we are not conscious of the blind spot.
Blind study
One in which the subject or the investigator (or both) are unaware of what trial product a subject is taking. See also double-blind study, single-blind study, triple-blind study.
Blinded medications
Products that appear identical in size, shape, colour, flavour, and other attributes to make it very difficult for subjects and investigators to determine which medication is being administered.
Blinded study
A study done in such a way that the patients or subjects do not know (is blinded as to) what treatment they are receiving to ensure that the results are not affected by a placebo effect (the power of suggestion).
Blinding/masking
A procedure in which one or more parties to the trial are kept unaware of the treatment assignments. Single-blinding usually refers to the subject(s) being unaware, and doubleblinding usually refers to the subject(s), investigators, monitor, and, in some cases, data analyst(s) being unaware of the treatment assignments.
Blindness
Legal blindness is defined as: 1) visual acuity of 20/200 (only being able to see the big E on the eye chart) or less in the best eye even with the eyes corrected by glasses or contact lenses; or, 2) The peripheral visual field is reduced to 20 degrees of visual angle or less. Twenty degrees of visual angle is about the size of a one foot ruler held at arms length.
Blindness, legal
See: Legal blindness.
Blindness, night
Impaired vision in dim light and in the dark, due to impaired function of specific vision cells (namely, the rods) in the retina.
Blindsight
A phenomenon reported in individuals suffering from cortical blindness (i.e. damage to the primary visual cortex resulting in blindness). Individuals with blindsight report that they are unable to see, yet under forced choice conditions are able to indicate the presence and location of visually presented objects.
Blink rate
The number of times per minute that the eyelid automatically closes -- normally 10 to 30 per minute.

In a parallel trial design, differences between subjects are used to assess treatment differences.
Bioavailability
Rate and extent to which a drug is absorbed or is otherwise available to the treatment site in the body.
Bioequivalence
Scientific basis on which generic and brand-name drugs are compared. To be considered bioequivalent, the bioavailability of two products must not differ significantly when the two products are given in studies at the same dosage under similar conditions.
Biostatistics
Application of statistics to biological and medical problems.

Brucella
A genus of encapsulated, nonmotile bacteria (family Brucellaceae) containing short, rod-shaped to coccoid, Gram-negative cells. These organisms are parasitic, invading all animal tissues and causing infection of the genital organs, the mammary gland, and the respiratory and intestinal tracts, and are pathogenic for man and various species of domestic animals. They do not produce gas from carbohydrates.
