GonioscopyIn ophthalmology, gonioscopy is a routine procedure that measures the angle between the iris and the cornea (the iridocorneal angle), using a goniolens (also known as a gonioscope) together with a slit lamp or operating microscope. Its use is important in diagnosing and monitoring various eye conditions associated with glaucoma. The goniolens allows the clinician - usually an ophthalmologist or optometrist - to view the irideocorneal angle through a mirror or prism, without which the angle is masked by total internal reflection from the ocular tissue.

Eye care professionalAn eye care professional (ECP) is an individual who provides a service related to the eyes or vision. It is any healthcare worker involved in eye care, from one with a small amount of post-secondary training to practitioners with a doctoral level of education. Ophthalmology Ophthalmologists are Doctors of Medicine (M.D./D.O.)(physicians) who specialize in eye care - this includes optical, medical and surgical eye care. They have a general medical degree, not a degree in eye care specifically.
Champ de vuedroite|vignette|L'angle de vue peut être mesuré horizontalement, verticalement ou en diagonale. Le champ de vue est la mesure du monde observable tel que vu à un temps donné. Dans le cas d'instruments d'optique ou de capteurs, c'est l'angle solide au travers duquel un détecteur est sensible aux rayonnements électromagnétiques. La capacité visuelle d'un animal n'est pas uniforme à travers le champ de vue, et varie d'un animal à l'autre.
Congenital red–green color blindnessCongenital red–green color blindness is an inherited condition that is the root cause of the majority of cases of color blindness. It has no significant symptoms aside from its minor to moderate effect on color vision. It is caused by variation in the functionality of the red and/or green opsin proteins, which are the photosensitive pigment in the cone cells of the retina, which mediate color vision. Males are more likely to inherit red–green color blindness than females, because the genes for the relevant opsins are on the X chromosome.
