entropion
a condition which the eyelid is rolled inward
causes scarring of conjunctiva
caused my msk spams and inflammation
hordeolum
aka sty
rapid onset
acute focal infection usually caused by staphlococcal
glands involved with hordeolum
zeis glands: external meibomian glands (less frequent) internal
chalazion
an obstruction of an meibomian gland drainage duct within the eyelid
usually slow onset and progress
difference between a hordeolum and a chalazion
sty is caused by an acute infective process- usually more painful
chalazion is caused by inflammatory process
hyphema
collection of blood in the anterior chamber
will effect vision
causes of hyphema
blunt trauma
increased inter-ocular pressure
sub-conjunctival hemhorrhage
ruptured vasculature under conjunctiva
- does not affect vision
- non-painful
causes of sub-conjuntival hemorrhage
valsalva maneuver (birth/strain) trauma hypertension medications idiopathic
papilledema
swelling of the optic disc from increased ICP
will appear fuzzy on fundoscopy exam
normal range 7-15 mmHg
indications of papilledema
brain tumor
cns inflammation
idiopathic intracranial hypertension
closed head trauma
pterygium
non-cancerous growth in the conjunctival tissue of the eye
grows to cover the sclera and extends down to the cornea
risk for development of pterygium
exposure to sunny, dusty, sandy or windblown areas
strabismus
aka crossed eyes
