RELATED TERMS--------------------------------------
Asthma
Asthma is a chronic, inflammatory lung disease characterized by recurrent breathing problems. People with asthma have acute episodes or when the air passages in their lungs get narrower, and breathing becomes more difficult. Sometimes episodes of asthma are triggered by allergens, although infection, exercise, cold air and other factors are also important triggers.
Bronchospasm
Contraction of the muscle in the walls of the bronchi.

Floaters
Small condensations of cells in the vitreous body, the fluid in the eye, which cast shadows on the back of the eye, known as the retina. This is normally associated with aging. Floaters may indicate a more serious problem such as a retinal detachment. If you suddenly see a lot of floaters, please see your eye doctor.
Fluorescein angiography
Fluorescein Angiography is a diagnostic test used to assess pathology that affects the retina, choroid and/or iris of the eye. Fluorescein angiography is used to assess the blood flow of the eye and abnormal states are referred to as either hyperfluorescence or hypofluorescence relative to the normal amount of fluorescence. Fluorescein angiography involves an intravenous injection of sodium Fluorescein ( a dye) into the antecubical vein ( a vein in the arm) and then photographs are taken of the eye as the dye enters and leaves the blood system of the eye. The doctor will evaluate prefilling ( i.e., what the retina and choroid look like before the dye enters the eye), transit ( i.e., first passage of dye through the retina and choroid), recirculation (i.e., fluoroscien has become equally distributed throughout the eye and then starts to circulate through again) and later phase ( i.e., as the fluoroscien is eliminated from the body by the kidneys). The test lasts about 30 minutes. Nausea and vomiting are the most common side effects, occurring in about 5% or less of patients. Severe side effects ( e.g., anaphylaxis, death) have been reported but are very rare.
Fovea
A central portion of the retina and macula that contains only cones. The fovea is the only part of the eye that is capable of 20/20 or better vision.
Fundus
The back part of the eye that can be seen with an instrument called an ophthalmoscope. Visible features include the retina with its blood vessels, the optic nerve and choroid. The fundus surrounds the fovea, that part of the eye used for reading.
Fundus flavimaculatus
See Stargardt’s disease.
