The most dangerous basal cell ulcer is known as a _____ b/c it can kill by relentless local invasion. Removal requires ____ margins.
rodent ulcer; 1mm
Typical location of rodent ulcer is in ____, which makes it cosmetically difficult, therefore surgeons use ____ surgery, which uses microscopic sections and tissue dx as excision is being done.
upper face; Mohs surgery
_____ cancer is usually seen on the lower lip and territories below the horizontal live drawn across the mouth. This cancer CAN mets to _____.
Squamous cell; regional LNs
Excision of Squamous cell carcinoma requires _____ margins. _____ may need to be biopsied or dissected; radiation is another treatment option

Pathology of melanoma MUST include the presence of cancer and _____
depth of invasion
Melanoma: _____ have good prognosis. ____ have bad prognosis and can be lethal.
superficial invasions; deep invasions
Melanomas less than ___ deep require local excision only. Those between _____ require 2cm margins and attention to LNs. Those greater than ____ have a terrible prognosis despite therapy.
1mm; 1 to 4mm; 4mm
MC locations of mets malignant melanoma
LNs, liver, lung, brain, bone, other “weird” places
Metastatic malignant melanoma has no predictable timetable. _____ is the current preferred adjuvant systemic therapy.
Interferon
____ is a vision impairment resulting from interference with the processing of images by the brain during the first 6 or 7 years of life. Most common presentation is a child with _____.

Strabismus is verified by showing that the reflection from a light comes from ______ in each eye.
different areas of the cornea
When strabismus not diagnosed right away, there can be exaggerated convergence caused by refraction difficulties. _____ instantly resolve the issue.
corrective glasses
A ____ in a baby is indicative of retinoblastoma and is an ophthalmologic emergency. It could also be a _____, but you must treat it right away to prevent amblyopia.
white pupil; congenital cataract
___ is a common source of blindness and is silent in nature so it is rarely discovered by PCP unless eye exam is done.
Glaucoma
_____ glaucoma shows up at very severe eye pain or frontal headache typically starting in the evening when the pupils have been dilated for several hours. Pt might say they are seeing ____ around lights.
Acute angle closure; halos
Acute angle closure glaucoma on physical exam shows a _____ pupil that [DOES/DOES NOT] react to light; the cornea has a _____ hue and the eye feels hard as a rock.
mid-dilated; does not; greenish
Emergency surgery for Acute angle closure glaucoma includes ______ to allow drainage of fluid trapped in the [ANTERIOR/POSTERIOR] chamber.
drilling a hole in the iris; anterior
While waiting for sx for Acute angle closure glaucoma, give ______ and apply topical ____. Mannitol and pilocarpine may also be used.

_____ is another emergency recognized by patients reporting “flashes of light” and “floaters”. The number of floaters tells you about the magnitude of the problem.
Retinal detachment
In retinal detachment, the person with one or two floaters may only have ______ of the retina, whereas a “snowstorm” of floaters or a big dark cloud at the top of the visual field indicates _______.
vitreous tugging; big horseshoe piece of retina pulling away and at risk for ripping of rest

embolic occlusion of retinal artery; 30 minutes
Intermittent tx for embolic occlusion of retinal artery
breathe into paper bag and have someone repeatedly press hard on eye and release [to vasodilate and shake clot into more distal location to prevent ischemia]
_____ patients MUST have an ophthalmologic evaluation. ___ damage may have already occurred at this time.
