30
Q

diplopia

A

Double vision

31
Q

pneumatic retinopexy

A

A gas bubble is injected into the vitreous cavity to put pressure on the area of the retinal tear until the retina is reattached

32
Q

fluorescein angiography

A

Intravenous injection of fluorescein (a dye) followed by serial photographs of the retina through dilated pupils

33
Q

ophthalmoscopy

A

Visual examination of the interior of the eye

34
Q

slit lamp microscopy

A

Examination of anterior ocular structures under microscopic magnification

35
Q

visual acuity test

A

Clarity of vision is assessed

36
Q

visual field test

A

Measurement of the entire scope of vision (peripheral and central)

37
Q

enucleation

A

Removal of the entire eyeball

38
Q

keratoplasty

A

Q

nerve deafness

sensorineural hearing loss

A

Impairment of the cochlea or auditory (acoustic) nerve

47
Q

conductive deafness

A

Impairment of the middle ear ossicles and membranes transmitting sound waves into the cochlea

48
Q
