- 30—Ptosis

- 31EntropionLid droops inward, lower lash may irritate conjunctiva and cornea
- 32EctropionLid droops outward exposing palpebral conjunctiva - when punctum gets blocked it causes poor drainage and tearing
- 33—Entropion

- 40—Dacrocystitis

- 41—Scleral Icterus (jaundice in eye)

- 42—Pterygium

- 43—Subconjunctival Hemorrhage

- 44PterygiumA triangular thickening of the bulbar conjunctiva that grows slowly across the outer surface of the cornea (usually from the nasal side)
- 45ConjunctivitisDiffuse dilatation of conjunctival vessels with redness that tends to be maximal peripherally. Can be viral, allergic, bacterial.
- 46StrabismusA deviation of the eyes from the normally conjugate position
- 47NystagmusFine, rhythmic oscillations of the eyes, normal for a few beats seen at terminal range of eye movement. Sustained indicates neurological condition. Lid lag can indicate hyperthyroidism
- 48Miosisconstriction of the pupils
- 49Mydriasisdilation of pupils
- 50AnisocoriaUnequal pupils
- 51AccommodationAbility of pupils to constrict when focus shifts from distance to close object
- 52ConvergenceAbility of eyes to move toward the nose symmetrically when following an object moving toward them.
- 53PERRLAPupils Equal, Round, Reactive to Light and Accommodation
- 54What muscle moves the eyes to the left and right?Lateral Rectus & Medical Rectus
- 55What muscle moves the eye up and down?Superior Rectus and Inferior Rectus
- 56Name the 6 cardinal gazes1. Medial Rectus
2. Lateral Rectus
3. Superior Rectus
4. Inferior Rectus
5. Superior Oblique
6. Inferior Oblique - 57What is the nerve innervation of lateral rectus?Abducens nerve (CN VI)
- 58What is the nerve innervation of superior oblique?Trochlear nerve (CN IV)
- 59What is the nerve innervation for the majority of the ocular muscles?Oculomotor nerve (CN III)
- 60FundusPosterior aspect of the eye seen through the ophthalmoscope
- 61Retinavisual screen and inner layer of the eye
- 62What does the optic disc contain?optic nerve (CN II), retinal vein and arteries
- 63FoveaA small depression in the retinal surface where largest concentration of cones are contained therefore the central point of vision
- 64Maculayellow oval around the fovea - acts as a natural blocker of UV light and sunblock for the fovea
- 65Physiologic cupdepression in the optic disc
- 66What is the red reflex?During a fundoscopic exam, it is the light reflecting off the retina. (absence of red reflex can mean cataracts or vitreous hemorrhage)
- 67What are the two types of glaucoma?1. open angle glaucoma (2nd leading cause of blindness in Americans)
2. acute closed angle glaucoma - 68A-V taperingThe vein appears to taper down on either side of the artery.
- 69A-V nickingvein abruptly stops on either side of the artery
- 70—A-V tapering

- 71—A-V nicking

- 72—Cotton-wool patches

- 73—Retinal Detachment

- 74What is a sit lamp examination and what does it examine?Magnifying device to examine anterior portion of the eye.
- cornea
- anterior chamber
- iris
- lens - 75Conjunctivaclear membrane covering the eye and the underside of the eyelids
- 76—Scleritis

- 77Nuclear Cataractlooks gray when seen by a flashflight
- 78Peripheral cataractProduces spokelike shadows that point gray against black, as seen with a flashlight, or black against red with an ophthalmoscope
- 79Arcus senilisRing around the iris. Common in elderly, From cholesterol deposits, may indicate hyperlipidemia.
- 80—Arcus Senilis

- 81—Peripheral Cataract

- 82—Nuclear Cataract

- 83Angle Closure Glaucomaa sudden elevation in intraocular pressure that occurs when the iris blocks the eye's drainage channel—the trabecular meshwork
- 84Extraocular MovementsTesting the function of each ocular muscle and the cranial nerve that supplies it by asking the patient to move the eye in the direction controlled by that muscle (H)
- 85Consensual reactionpupillary constriction in the opposite eye
- 86What does the swinging flashlight test examine for?Used to test for impairment of optic nerves II and III
- 87How do pupils constrict?Reflex arc is initiated by reaction to light: CN2 (afferent) and CN3 (efferent)
CN3: parasympathetic innervation, pupil constricts
Sympathetic: dilate - 88Name possible retinopathies for diabeticsHard exudates
Cotton wool patches
Deep hemorrhages - 89Name possible retinopathies for hypertensivesAV tapering, nicking, banking
Copper wiring
Hard exudates
Papilledema
