Cheat Sheet
- Refractive Power of Cornea and Lens -
The cornea contributes about two-thirds (~42 diopters) of the eye's total refractive power, while the crystalline lens adds the remaining ~18D for fine focus (NEI, University of Iowa). Use the formula P_total = P_cornea + P_lens to understand accommodation and common refractive errors in your eye practical quiz. Memorize that most refraction happens at the air - cornea interface for quick recall.
- Retinal Layers and Photoreceptors -
The retina's multi-layered structure houses rods for scotopic (low-light) vision and cones for photopic (color) vision, with the fovea centralis packed densely with cones for highest acuity (Guyton & Hall). A handy mnemonic, "PPRG" (Pigment epithelium, Photoreceptors, Bipolar cells, Ganglion cells), helps you recall outer-to-inner retinal layers. This is essential knowledge for any eye anatomy quiz or ocular anatomy quiz section on sensory transduction.
- Aqueous Humor Dynamics -
Aqueous humor is secreted by the ciliary body into the posterior chamber, flows through the pupil, and drains via the trabecular meshwork into Schlemm's canal (Johns Hopkins Ophthalmology). Understanding this pathway is key to grasping intraocular pressure regulation and glaucoma pathophysiology in an eye practical assessment. Remember: "C-P-T-S" (Ciliary body → Pupil → Trabecular meshwork → Schlemm's canal).
- Extraocular Muscle Innervation -
Six muscles control eye movements; lateral rectus uses CN VI, superior oblique uses CN IV, and all others use CN III (LR6 SO4 R3). This concise rule is often tested on parts of the eye and ocular structure questions in the eye structure quiz. Practice drawing the muscle orientations with their cranial nerve numbers for visual reinforcement.
- Visual Pathway to Cortex -
Retinal ganglion cell axons form the optic nerve, partially decussate at the optic chiasm, continue as optic tracts to the lateral geniculate nucleus, then project via optic radiations to V1 in the occipital lobe (NIH NINDS). Diagrams of this pathway are staple slides in any eye anatomy quiz and help you predict visual field deficits clinically. Use the phrase "ON-Chiasm-OT-LGN-V1" to lock in each segment's order.
