|
cornea
|
fibrous, transparent tissue that extends like a dome over the pupil and iris.

|
optic chiasm
|
point at which optic nerve fibers cross in the brain.
(Latin chiasma means crossing)) |
|
|
astigmatism
|
defective curvature of the cornea or lens of the eye.
|
|
|
glaucoma

increased intraocular pressure results in damage to the retina and optic nerve with loss of vision.
|

tonometry
|
measures intraocular pressure to detect glaucoma. (ton/o=tension)

|
LASIK
|
Use of an excimer laser to correct errors of refraction (myopia, hyperopia, and astigmatism).

|
|
photocoagulation
|
intense, precisely focused light beam (argon laser) creates an inflammatory reaction that seals retinal tears and leaky retinal blood vessels.

|
rods
|
photoreceptor cell of the retina essential for vision in dim light and for peripheral vision.

photoreceptor cell in the retina that transforms light energy into a nerve impulse. Cones are responsible for color and central vision.
