Eye Assessment Flashcards

Ptosis
Drooping of eyelid

Entropion
Inward turning of eyelid

Ectropion
Outward turning of eyelid

Lid retraction; Exopthalmous
Retracted lid and lid lag; bulging eyes

Corneal Arcus
Blue hue surrounding peripheral cornea

Corneal Scar
Superficial gray-white opacity in cornea

Pterygium
Triangular thickening of bulbar conjunctiva growing outward from nasal side
Cataracts
Opacities of lenses visible through pupil

Nuclear cataract
Gray when seen by flashlight

Peripheral cataract
Gray, spotlike shadows pointing inwards

Conjunctivitis
Diffuse dilatation of conjunctival vessels with redness that’s peripherally maximal

Subconjunctival Hemorrhage
Leakage of blood outside vessels; homogeneous demarcated red area
Corneal Injury/Infection; Acute Iritis; Glaucoma
Ciliary injection: dilation of deeper vessels visible as radiating or reddish-violet flush around limbus; diffusely red.
Pseudostrabismus

Temporary strabismus at birth/infancy

Esotropia
Cross-eyed
Permanent malallignment

Exotropia

Blindness
Loss of vision/visual acuity
Vision is = 20/200

Anisocoria

Lesion of optic nerve or eye

Bitemporal Hemianopsia
Temporal peripheral vision loss in both eyes; no peripheral vision
Due to lesion in optic chiasm

Left Homonymous Hemiopsia
Vision loss on same side in each eye
Due to lesion in Right optic tract or right optic radiation

Homonymous Left Superior Quadrantic Defect
