Anatomy
What are the 2 types of photoreceptive cells?
rods and cones
A degenerative condition affecting the central part of the retina and resulting in distortion or loss of central vision is called?
(It occurs especially in older adults, drusen are the defining feature of this disease)
age-related macular degeneration
Treatment for advanced cases of diabetic retinopathy using lasers to shrink blood vessels in your eye that are causing vision problems
panretinal photocoagulation
The part of the eye responsible for our blind spot is called?
optic disk
The muscle responsible for blinking is called?
orbicularis oculi muscle
An inherited degenerative disease that slowly affects the retina and causes loss of night and side vision is called?
retinitis pigmentosa
A procedure to repair a detached retina and restore vision in which a gas bubble is injected into the eye, then a freezing device is used to seal the retina against the wall of the eye.
pneumatic retinopexy
The top layer of the Retina is called?
pigmented epithelium
The pigmented vascular layer of the eyeball between the retina and the sclera is called?
choroid
A thin sheet of fibrous tissue that can develop on the surface of the macular area of the retina and pulls up on the retina, which distorts your vision and may make objects appear blurred or crooked is called?
epiretinal membrane
A surgical procedure used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye's trabecular meshwork and adjacent structures.
Trabeculectomy
The small depression in the retina of the eye where visual acuity is highest is called?
Fovea
The place in the brain where some of the optic nerve fibers coming from one eye cross optic nerve fibers from the other eye is called?
Optic Chiasm
A disease resulting in a sudden rise in intraocular pressure as a result of the angle between the iris and cornea closing is called?
(Symptoms and damage that are usually very noticeable in contrast to the more common type of this disease which develops slowly)
angle-Closure, acute, or narrow-angle glaucoma
A group of medicines given as an injection which reduce new blood vessel growth (neovascularisation) or edema (swelling)
Anti–vascular endothelial growth factor therapy (Anti-VEGF)
The strucutre where the retinal artery (arteria centralis retinæ) pierce the optic nerve, and enter the bulb of the eye through is called?
porus opticus
The unique vascular structure that functions to maintain fluid homeostasis by draining aqueous humor from the eye into the systemic circulation is called?
schlemm's canal
An infection (viral) that attacks the light-sensing cells in the retina is called?
(It is most often diagnosed in patients with a severely compromised immune system, including those with AIDS or those on chronic immunosuppressive therapy following organ transplantation)
cytomegalovirus

The pigmented cell layer just outside the neurosensory retina that nourishes retinal visual cells, and is firmly attached to the underlying choroid and overlying retinal visual cells is called?
retinal pigment epithelium
