H.E.E.N.T Flashcards
- Acute onset of severe eye pain, photophobia, and blurred vision in one eye.
- “Fern-like” lines in the corneal surface are a positive sign.
- Infection permanently damages corneal epithelium, which may result in corneal blindness.
- Herpes Keratitis
Diagnostics for Herpes Keratitis is:
- Fluorescein Dye, and…

- An ophthalmologic emergency
* Acute onset of severe eye pain, accompanied by headache, nausea/vomiting, halos around lights, and decreased vision.
- Acute Angle-Closure Glaucoma
What does the examination of “acute angle-closure” glaucoma reveal?
- Examination reveals a mid-dilated pupil (oval shape)
- Fundoscopic exam reveals cupping of optic nerve
- Cloudy corneas
- Cauliflower like growth accompanied by foul-smelling ear discharge.
- Hearing loss reported on affected ear.
- Tympanic membrane ad ossicles are NOT VISIBLE.
- NON-CANCEROUS
- Cholesteatoma
- Cholesteatoma is associated with
- History of chronic Otitis Media
- Bilateral condition manifesting as a white ring around the cornea.
- It is a benign variant in the elderly
- It is associated with ↑ cholesterol and ↑ triglycerides in the young adult
- Arcus Senilis
- Common “NON-CANCEROUS” growth of the conjunctiva.
- A yellow triangular thickening of the bulbar conjunctiva.
- Located on the “inner and outer margins of the cornea”
- May be associated with long-term sunlight
- Pinguecula

- Battle Sign
If a basilar skull fracture is noted, what should the practitioner check for?
- Check for CSF FLUID. It can slowly leak through the fracture
- Sore throat and “low-grade” fever
- Markedly swollen neck (bull neck)
- Hoarseness and dysphagia
- A “Pseudomembrane” is located on the pharynx, uvula, tonsils, and soft palate.
- Diptheria
- A yellow triangular thickening of the conjunctiva that extends on the “nasal or temporal” side of the cornea.
- Caused by UV light damage
- Pterygium
- Sore red eyes with increase tearing
- No reports of purulent discharge
- Higher risk with autoimmune disorders (RA, lupus, ankylosing spondylitis), sarcoidosis, and syphilis.
- Anterior Uveitis
Part of the eye that is responsible for color and night vision
- Cones (also responsible for high spatial acuity)
What is a normal result of the Rinne Test
- Air conduction is greater than bone conduction
The Cover/Uncover test is used to screen for?
- Strasismus
Vertical nystagmus is _______, but horizontal nystagmus after a lateral gaze is ________
- Vertical Nystagmus is Abnormal
* Horizontal (a few beats) is Normal
Peripheral vision is examined with the:
- Visual fields of confrontation
Legal blindness is considered when
- Best corrected vision is 20/200
* Visual field is less than 20 degrees
The area of the eye that determines 20/20 vision
Fovea (Macula and Fovea)
- White spots that appear on the surface and under the tongue.
- May be cancerous.
- A sign in patients with a history of chewing tobacco
Leukoplakia
- Normal range of Intraocular Pressure is
