HEENT Flashcards
Lesion is at the optic chiasm
Bitemporal Hemianopsia
Occlusion of a branch of the central retinal artery; Ischemia of the optic nerve can also produce the similar defect
Horizontal Defect
Causes Ptosis (3)
- Myasthenia Gravis
- CN 3 damage
- Damage to sympathetic nerve supply (Horner Syndrome)
A harmless yellowish triangular nodule in the bulbar conjuctiva
Pinguecula
Localized ocular inflammation of the episcleral vessels
Episcleritis
Causes Episcleritis (3)
- Rheumatoid Arthritis
- Sjogren Syndrome
- Herpes Zoster
A painful, tender, red infection at the margin of the eyelid
Hordeolum (Stye)
A subacute non-tender nodule caused by a blocked meibomian gland
Chalazion
Slightly raised, yellowish, well-circumscribed cholesterol-filled plaques that appear along the nasal portions of one or both eyelids
- Xanthelesma
A thin grayish white arc or circle not quite at the edge of the cornea
Corneal Arcus
A golden to red brown ring, sometimes shading to green or blue, from copper deposition in the periphery of the cornea found in Wilsons Disease
Kayser-Fleischer Ring
A superficial grayish white opacity in the cornea, secondary to an old injury or to an inflammation
Corneal Scar
A triangular thickening of the bulbar conjunctiva that grows slowly across the outer surface of the cornea, usually from the nasal side.
Pterygium
Opacities of the lenses visible through the pupil.
Cataract
Risk factors of Cataract (4)
- Older age
- Smoking
- Diabetes
- Corticosteroid use
Cataract that looks gray when seen by a flashlight
Nuclear Cataract
Cataract - if the pupil is widely dilated, the gray opacity is surrounded by a black rim
Nuclear Cataract
Cataract - produces spokelike shadows that point - gray against black, as seen with a flashlight, or black against red with an ophthalmoscope
Peripheral Cataract
Effect on pupil when Anisocoria is greater in dim light than in bright light
the smaller pupil cannot dilate properly caused by an interruption of the sympathetic nerve supply
Effect on pupil when Anisocoria is greater in bright light than in dim light
the larger pupil cannot constrict properly
Causes of Anisocoria where it is greater in bright light than in dim (4)
- blunt trauma
- open-angle glaucoma
- impaired parasympathetic nerve supply to the iris
- occulomotor nerve paralysis
Pupil is large, regular and usually unilateral
Tonic Pupil (Adie’s Pupil)
The dilated pupil is fixed to light and near effort
CN III Paralysis
Horner’s Syndrome symptoms (6)
S ympathetic A nhidrosis M iosis P tosis L oss of Ciliospinal Reflex E nopthalmos
Small, irregular pupils that accommodate but do not react to light
- Argyll Robertson
- Central Nervous System Syphilis
The affected pupil, though small, reacts briskly to light and near effort
Horner’s Syndrome
Caused by an imbalance in ocular muscle tone
Developmental Dysconjugate Gaze
CN6 Paralysis
Estropia appears when looking straight ahead
CN 4 Paralysis
cannot look down and in
Test for convergence is poor in ____
Hyperthyroidism
A small whitish depression in the optic disc, the entry point for retinal vessels
Physiologic Cup
These are developmental variations that appear as either white sclera, black retinal pigment, or both, especially along the temporal border of the disc
Rings and Crescents
What is the normal appearance of the Optic Disc (4)
- Color yellowish orange to creamy pink
- Disc vessels are tiny
- Disc margins are sharp (except perhaps nasally)
- Physiologic cup is located centrally or somewhat temporally
Appearance of Optic Disc during Papilledema (5)
- Color pink, hyperemic
- Often loss of venous pulsations
- Disc vessels more visible, more numerous, curve over the borders of the disc
- Disc swollen with margins blurred
- Physiologic Cup is not visible
Appearance of Optic Disc during Glaucomatous Cupping (2)
- Physiologic cup is enlarged, occupying more than half of the disc’s diameter, at times extending to the edge of the disc
- Retinal vessels sink in and under it, and may be displaced nasally
Appearance of Optic Disc during Optic Atrophy (2)
- color white
- Tiny disc vessels are absent
Small, linear, flame-shaped, red streaks in the fundi
Superficial Retinal Hemorrhages
Diplopia in one eye, with the other closed suggests a problem in the
Cornea
What do tragal or mastoid tenderness signify?
Middle ear infection (Otits Media)
Movement of the auricle and tragus (tug test) is painful in
Acute otitis externa
Rounded bony growth in the inner surface of the mandible. It is typically bilateral, asymptomatic and harmless.
Torus mandibularis
Valsalva maneuvers and leaning forward may increase pain from
Acute sinusitis
A subacute nontender, usually painless nodule caused by a blocked meibomian gland may become acutely inflamed usually points inside the lid.
Chalazion
There is thickening of the arterial wall, causing focal or generalized narrowing of the lumen and the light reflex.
Retinal arteries in hypertension
Occasionally the wall of narrowed artery becomes opaque so there is no visible blood.
Silver Wiring
Sometimes the arteries become full and somewhat tortuous and develop an increased light reflex with a bright coppery luster.
Copper Wiring
This headache is generalized, very severe “the worst of my life”
Thunderclap (Subarachnoid hemorrhage)
A sudden visual loss that is painless and unilateral. Consider the following causes (6)
- Vitreous Hemorrhage from Diabetes
- Trauma
- Macular Degeneration
- Retinal Detachment
- Retinal Vein Occlusion
- Central Retinal Artery Occlusion
Sudden, Unilateral, Painful Visual Loss (5)
- O ptic Neuritis from Multiple Sclerosis
- T raumatic Hyphema
- A cute Angle Closure Glaucoma
- C orneal Ulcer
- U veitis
there specks in the vision or areas where the patient cannot see
Scotomas
Headache:
One side of the head, light and sound sensitivity
Migraine
Headache:
Band around the head, Aching pressure, triggered by stress
Tension Headache
