2 Flashcards
Location of goblet cells
Epithelium of conj
What 4 layers of the eyelid contain the aponeurosis of the levator palpebrae
Epidermis
Submuscular areolar
Subcutaneous areolar
Orbital septum
Descemet’s
- hydrops
- hassall-henle bodies
- haab’s striae
Hydr: ruptured D, corneal ectasias (Kconus, Kglobus, pellucid)
HHB: thickened (Fuchs)
HS: folds/ruptures in D (cong glauc)
Vogt’s striae
Keratoconus late sign
Vertical lines in deep stroma
Disappear with pressure
Assoc with aniridia (5)
PAS Foveal hypoplasia -> nystagmus ON hypoplasia Lens subluxation Microcornea
How PGAs decr IOP
Relax CM -> incr spacing bw muscle fiber bundles -> incr uveoscleral AH flow
Where are they
- drance
- dot/blot
- flame-shaped
- CWS
Dot/blot = INL (bigger supply)
Drance, flame-shaped, CWS = NFL
3 common findings with phacomorphic glaucoma
Large intumescent cataract
Schwalbe’s most posterior structure visible on gonio
PAS
Phacomorphic = 1 of 3 types of POAG
Which 2 CNs carry PNS fibers that incr lacrimation
7
5
The primary difference bw juxtamedullary and cortical nephrons is the length of the
Thin segment of the LOH
Drugs that undergo 1st pass metabolism are delivered to the liver by what vessel
Portal vein
Cells from a choroidal melanoma most commonly metastasize to the liver by traveling thru which vessel
Hepatic artery
Poor nutrient exchange b/w small intestine and liver is most likely due to damage to
Portal vein
Ganglion that provides PNS innervation to the lacrimal gland
Pterygopalatine
Blood supply to the eyelid (3)
Lateral and medial palpebral arteries
Branches of facial arteries
Iris anterior vs posterior stromal leaves
Ant: ABL + small portion of stroma in ciliary zone
Post: most of iris stroma in ciliary zone, all of stroma in pupillary zone, and anterior border leaf
Cycloablation decr IOP by targeting
Pars plicata (corona ciliaris)
*pars plana = orbicularis ciliaris
Gracilis tract
Propioception: touch, pressure, vibration of lower body
Decussate in medulla
Impaired release of melatonin in most likely to result from damage to
Epithalamus - contains pineal gland
Lobe:
- broca’s
- wernicke’s
B: frontal
W: temporal
Craniopharyngioma VFD
Bitemporal hemianopsia more dense inferiorly (superior fibers)
Which ocular dominance columns rec’v input from both eyes (assume healthy pt)
2-6
Which specific part of the eye is tested
- EOG
- ERG
EOG: RPE
ERG:
- A wave = PR
- B wave = BP
- C wave = RPE
Head tilt with damage to
- right superior oblique innervation
- right superior oblique nucleus
Left head tilt
Right head tilt (R nucleus = L SO = R head tilt)
CSCR is most likely to occur from hyperactivity of SNS fibers traveling with which nerve
SPCNs
- SNS fibers that innerv choroidal BVs follow V1 to ciliary ganglion -> pass thru and follow SPCNs to choroid
- hyperactivity -> localized damage to Bruch’s -> CSCR
4 sinuses at the confluence
Occipital
Transverse
Straight
Superior sagittal
Which of the following do not display center-surround fields: horizontal, ganglion, amacrine, biopolar
Horizontal
SPCAs supply (4)
Posterior choroid (cherry red spot)
Circle of Zinn
Outer retina
Cilioretinal artery
Layers of cornea and thickness
Epi 50 (z occludens) Bowmans 10 Stroma 450 Descemets 5-15 Endo 5 (m occludens)
Where are Hallers and Sattlers layers
Choroidal stroma
-sattlers = superficial
