Q

Anterior chamber Angle

A

formed by junction of cornea and iris

22
Q

Herpes Simplex Virus

A
  • corneal infection can lead to scarring
  • corneal infection characterized by dendritic pattern
  • causes fever blisters or “cold sores”
  • caused by chicken pox
23
Q

Structures involved in creating focused visual image

A
  • lens
  • retina
  • cornea
24
Q

What structure blocks aqueous outflow channel in the anterior chamber in primary angle-closure glaucoma

25
Ischemic process
reduction in blood flow to an organ or structure | i.e. heart attacks, strokes, retina artery occlusions
26
Neoplastic process
solid tissue growth or tumor that may be benign or malignant | i.e. Melanoma of choroid
27
Hydrophobic
resists water
28
Acute angle-closure glaucoma
* elderly pt * negative for POH * nausea * sudden onset pain OD * blurred vision w/haloes around lights
29
Polycarbonate lenses
* recommended for safety glasses | * recommended for pts with vision in only one eye
30
Thyroid ophthalmology can cause:
* strabismus | * proptosis
31
Important in assessing glaucoma
* visual field * measure corneal thickness * IOP check
32
Ocular manifestations of systemic disease
* proptosis w/exposure keratopathy * diabetic retinopathy * sjogren syndrome
33
Cells found in conjunctiva
goblet cells
34
Part of eye involved in focusing light
Cornea and Lens
35
Open-angle Glaucoma
common in elderly
36
What tissues compose the uveal tract
* iris * ciliary body * choroid
37
What structure attaches to elevator muscle
tarsus
38
Common ocular manifestations of myasthenia gravis
ptosis and diplopia
39
Dacryocystitis
inflammation of lacrimal sac
40
Papilledema
caused by increased intracranial pressure
41
Hypopyon
layer of pus (white blood cells) in anterior chamber
42
Found in anterior segment of eye
* schlemm's canal * lens * aqueous humor
43
Cells found in retina
* ganglion cells * bipolar cells * rod cells
44
Medial rectus
extraocular muscle that adducts the eye (turns it inward)
45
Varicella-zoster
painful skin eruptions across the left/right side of his forehead that extends onto his left/right (same side) scalp area
46
Structure that light passes through before reaching the photoreceptors (rods and cones)
ganglion cells
47
Optic Neuritis
* inflammation of the optic nerve | * associated with multiple sclerosis
48
Endothelium
corneal tissue that pumps fluid out of cornea
49
Range of the wavelengths of visual light
400 to 750 nanometers
50
Hormones produced by endocrine system
* thyroxine * insulin * estrogren
