- Vessel layer/stroma of the choroid has two layers
- HaLler's layer = outer, Larger vessels
- Sattler's layer = inner, Smaller vessels
- An easy way to remember where the optic nerve head is
- Nerve head is in Nasal retina (therefore the blind spot is in temporal visual space)
- How to remember the levator's innervation
- Imagine the levator being held up by three columns (CN III)
- Innervation of the extraocular muscles (EOMs)
- Lateral Rectus innervated by CN VI, Superior Oblique by CN IV, all other EOMS = CN III
- Mnemonic = "LR6 SO4, all others CN III"
- The eight orbital branches of the ophthalmic artery = "PSALMS MD"
- Posterior ethmoidal
- Supraorbital
- Anterior ethmoidal
- Lacrimal
- Muscular branches
- Supratrochlear
- Medial palpebral
- Dorsal nasal
- What feeds the superior ophthalmic vein = "APL MASC"
- Anterior ethmoidal
- Posterior ethmoidal
- Lacrimal
- Muscular branches
- Anterior ciliary veins
- Superior vortex (lateral & medial)
- Central retinal vein
- Three branches of the ophthalmic nerve = "NFL"
- Nasociliary
- Frontal
- Lacrimal
- How to remember the function of the Gland of Moll
- Functions as a sweat gland - mnemonic = "Sweaty Molly"
- Glands of the conjunctiva = Little Kittens Walking Go to My Home
- Serous:
- Lacrimal
- Krause
- Wolfring
- Mucin:
- Goblet
- Manz
- Henle (crypts of)
- A simplified figure of how the nasal retinal fibers decussate
- Simply memorize and be able to reproduce this drawing:
- How to remember the difference between the Parvocellular and Magnocellular pathways of the LGN
- Think Parvocellular as "Puny" therefore tiny, which implies very fine ("tiny") detail; also involves contrast sensitivity, spatial resolution, color vision, detection of low temporal, and high spatial frequencies (hence fine detail)
- Remember, the Magnocellular involves high temporal and low spatial frequencies
- How to remember that Asians have narrow angles
- Think of narrow fissures ("narrow eyes") therefore narrow angles [note that this is not necessarily a correlation, but a way to memorize this]
- Retinal layers = "RPE o-NP i-NP GNI"
- Retinal Pigment Epithelium (RPE)
- Photoreceptor layer
- External Limiting Membrane
- outer Nuclear Layer
- outer Plexiform Layer
- inner Nuclear Layer
- inner Plexiform Layer
- Ganglion Cell Layer
- Nerve Fiber Layer (NFL)
- Inner Limiting Membrane
- How to remember what a sudoriferous cyst looks like
- "Sudoriferous" sounds like "suds" i.e. bubble suds, and they actually do look like bubbles and have a translucent appearance
- How to remember Hudson-Stahli line's deposit
- "Stalin ruled with an Iron fist" - Hudson-Stahli involves iron deposits in the cornea
- Episcleritis involves the 70/30 rule
- 70% simple, female, unilateral, idiopathic
- 30% nodular, male, bilateral, systemic
- How to know what is infected in Dacryoadenitis vs. Dacryocystitis
- Dacryadenitis involves an infected lacrimal gland
- Dacrycystitis has the "s" sound in "cys" and therefore you can associate it as an infected lacrimal sac
