NBEO Part I study plan

Draw from memory a labeled cross-section of the globe and the anterior chamber angle, then correct it against a standard histology text until every structure is placed accurately

Label the layers of the retina in correct order and state which cell type and which vascular supply (central retinal artery vs choriocapillaris) serves each layer

Trace the full afferent visual pathway from photoreceptor to striate cortex, naming each synapse, decussation, and the blood supply of each segment

Explain aqueous humor production, trabecular vs uveoscleral outflow, and the ionic transport mechanisms that drive each, in writing without notes

Build a one-page summary table of corneal layers with their regenerative capacity, innervation, and pump function

Explain the phototransduction cascade step by step, including the role of rhodopsin, transducin, phosphodiesterase, cGMP, and the dark current, and identify where each step can be pharmacologically or pathologically interrupted

Compare rod and cone function on sensitivity, temporal resolution, adaptation, and distribution, and state the clinical consequence of each difference

Describe tear film composition and the contribution of each gland to the lipid, aqueous, and mucin layers, and predict which layer fails in a given presentation

Explain corneal transparency in terms of stromal collagen spacing, relative dehydration by the endothelium, and the consequence of each failing

Summarize the metabolic pathways of the lens and the biochemical basis of cataract formation in diabetes and galactosemia

Derive and apply vergence, thin-lens, and thick-lens equations to calculate image position, magnification, and power for at least 15 numerical problems without looking up formulas

Calculate the power of a spherical refracting surface and convert between reduced, front, and back vertex distances for a given lens

Compute prism diopter deviation, induced prism at the optical center, and Prentice's rule for decentered lenses in at least 10 practice problems

Explain diffraction, interference, and polarization in the context of at least three clinical instruments or tests

Predict how changes in pupil size, wavelength, and target luminance shift visual acuity and contrast sensitivity, and justify each prediction from the underlying physics

Diagram the actions of each extraocular muscle in primary, elevation, and depression positions and explain the role of the oblique muscles in torsion

Trace the supranuclear control of horizontal and vertical gaze, including the paramedian pontine reticular formation, medial longitudinal fasciculus, and rostral interstitial nucleus of the medial longitudinal fasciculus, and predict the deficit from a lesion at each site

Apply Hering's and Sherrington's laws to interpret a cover test finding and identify the paretic muscle in at least five written case vignettes

Explain sensory fusion, Panum's area, and the neural basis of stereopsis, and calculate expected stereoacuity from a given interpupillary distance and viewing distance

Describe the development of binocular vision and the critical period, and state the rationale for amblyopia therapy timing

Perform and record retinoscopy and subjective refraction technique steps in correct sequence, and state the criteria for endpoint in each

Interpret a keratometry or corneal topography readout and classify a pattern as regular astigmatism, irregular astigmatism, or ectasia with stated reasoning

Compare spectacle, soft toric, rigid gas-permeable, and orthokeratology correction for a given refractive and corneal profile, and justify the recommendation

Build a drug table covering mechanism, concentration, dosing, and key adverse effects for at least 15 topical ophthalmic agents across glaucoma, anti-infective, anti-inflammatory, and diagnostic classes

Predict the ocular and systemic side effects of a given drug from its receptor pharmacology, including beta-blocker, alpha-agonist, cholinergic, and corticosteroid examples

Describe the cardinal pathologic processes (inflammation, repair, neoplasia, degeneration) and match each to at least two ocular examples with the microscopic finding named

Classify ocular tumors by cell of origin and site and state the histologic feature that distinguishes each from its main mimic

Compare the major bacterial, viral, fungal, and protozoal causes of keratitis and endophthalmitis on stain, culture, and typical clinical pattern

Explain innate versus adaptive ocular immunity, the concept of immune privilege, and the mechanisms that maintain it

Explain hypersensitivity types I through IV with one ocular example of each and the cell or antibody responsible

Build a system-by-system map linking at least 12 systemic diseases to their earliest and most characteristic ocular findings and the recommended referral urgency

Explain the ocular risk stratification for diabetes and hypertension and state the interval at which each should be re-examined

Interpret sensitivity, specificity, positive and negative predictive value, and likelihood ratios, and explain why predictive value changes with prevalence

Identify the study design used in a given abstract and name its main bias and the appropriate measure of association

Calculate and interpret confidence intervals, number needed to treat, and statistical versus clinical significance for a short trial result

Apply informed consent, confidentiality, scope of practice, and duty-to-refer principles to at least six written ethical scenarios and justify each decision by principle rather than preference

State the legal standard of care and the elements of malpractice, and identify which element is most often contested

Complete two full timed mixed-domain practice blocks and categorize every missed item by domain and by error type (knowledge gap, misread, calculation, or guessing)

Re-review only the highest-frequency error categories from the practice blocks and rewrite the underlying rule for each in your own words

Recite from memory the top five facts for each of the 12 domains as a final consolidation pass
