What is ptosis? dropping of the upper eyelid (CNIII)
What is Blepharitis? inflammation of the eyelid with associated crusting and itching. Caused by infection or autoimmune conditions. Expect so tbe more generalized than a stye or chalazion
What is hordeolum? stye. Infection of the sebaceious glands at the base of eyelashes. Usually staph. Painful
What is chalazion? a blockage of the meibomian glands on the endge of th eyelid. NOT painful
What is the conjunctiva? clear membrane as opposed to the white sclera covering the eye surface. Keeps the eye most and serves as a barrier to microbial invasion
What is conjunctivitis? inflammation of the conjunctivae caused by infection or allergic reactions. Usually associated with an erythematous, cobblestoned appearance, especially on the posterior surface of the eyelid
What is the arcus senilis of the Cornea ring around the edge of the cornea caused by lipid deposition. Normal finding in patients > 60 y/o.
What is the corneal light reflex? shine penlight directly at patient's eyes. Look for the reflection off the cornea. It should shine equally on the nasal portion of each cornea. Aysmmetry indicates strabismus or amblyopia
What is strabismus? patient cannot focus both eyes on an object simultaneiously. May have defvfaion of one eye out of position. Called lazy eye
What is exopthalmos? bulging eyes. Increased volume of orbital content. if bilateral, commonly associated with hyperthyroidism. Grave's disease is a common cause of autoimmune induced hyperthyroidism especially in women If UNILATERAL suspect retro-orbital tumor or mass
Waht is anisocoria? unequeal pupils Normal in 20% of people but may be associated with destruction of teh sympathetic or parasympathetic pathways during trauma
What is miosis pinpoint pupils Opiod abuse
What is mydriasis abnormally dilated pupils. midbrain lesions, hypoxia, CN III damage. Acute angle glaucoma, drug abuse
What should you suspect if the pupils fail to constrict? PSNS problems
What should you suspect if pupils fail to dilate think SNS problems
What is horner's syndrome? hi-sided loss of cervical sympathetic innervation to face and eye. Results in ipsilateral ptosis, miosis, vasodiation and anhydrosis. May be congenital, trauma or cancer
What is CN III Palsy damage to CN III which results in ptosis, mydriasis and abducation and depression of the pupil
What is cataracts? clouding or increased opacity of teh lens leading to blurring of loss of vision. Risk factors: increased age, corticosteroid use, UV light exposure, smoking, diabetes
What is retinoblastoma malignant tumor of the retina often found in children < 2 yo. usually present with loss of the reflex in the affected eye adn replacement with a white reflex instead
What is glaucoma? disease consisting of damage to the optic nerve usually caused by increased intr-ocular pressure frmo blocked exit of the aqueous humor fromt eh anterior chamber of the eye
What is open angle glaucoma? chronic glaucoma Trabecular meshwork becomes blocked over time. Often asymptomatic except for gradual loss of vision over a period of years. tiny blind spot appear at teh edges of teh visual field. colored halos around lights
Waht is closed angle glaucoma? opening between the cornea and iris narrows resulting in a rapid buildup of pressure. Intense ocular pain, blurred vision, visual halows, red eyes, dilated pupils or rapid loss of vision
What are the physical findings of glaumoa? cupping of the optic disc, hemorrhages around the edge of the optic disk
What are the normal structures seen in fundoscopic examination? fundus optic disc macula lutea fovea
Where is fundus found? posterior retina
Describe the optic disk where vessels and nerves enter the eye. Shoudl be yellow to creamy pink with well definded margins
Describe teh macula lutea yellowish area without blood vessels where visual acuity is heightened. Contains teh fovea
Describe the fovea area of highest visual acuity on the retina. Within the macula lutea
What is papilledema? increased intracranial pressure. Optic disc looses definition and pushed out central vessels.
What is glaucomatous cupping of the optic disc? caused by increased intra-ocular pressure and the death of ganglion cells secondary to glaucoma. cupping around the edges of the optic disc. Blood vessels may disappear around the edge of the disc
What are drusen bodies? usually caused by aging, associated with senile macular degeneration. Small discrete yellow spots on the retina that enlarge over time
What is diabetic retinopathy? dot hemorrhages, hard exudates, soft exudates ("cotton wool spots") Local hypoxia leads ot neovascularaion but the new vessels are weak adn leak easily leading to hemorrhage and vision loss
What is hypertensive retinopathy? increased light reflex from teh arterioles. Thre is narrowing adn AV nicking. Shiny retina, cotton wool spots. Flame hemorrhages, pailledema (late findig) Normal arterial-venous size ration is 3:5 and it will be decreased in hypertensive retinopathy
What is difference between diabetic retinopathy and hypertensive retinopathy? in HTN retinopathy look for AV nicking. It appears wehre an arteriole adn vein cross over each other.
AV nicking is associated with? hypertensive retinopathy
What are cotton woll spots infact areas assocaited with diabetic retinopathy or HTN retinopathy
Neovascularization diabetic retinopathy
Drusen bodies macular degeneration and aging
Hemorrhage at teh edge of optic disc glaucoma
flame hemorrhages diabetic retinopathy or HTN retinopathy
Retinal hemorrhages in infant SHAKEN BABY SYNDROME!!!!
