Arab Board Ophthalmology Part 1 study guide
Arab Board Ophthalmology Part 1 · Work through your exam, one topic at a time.
The Arab Board Ophthalmology Part 1 is the written, multiple-choice entry examination that candidates sit before progressing to the clinical and advanced stages of ophthalmology training under the Arab Board of Health Specializations. It is designed for residents and trainees at the start of their specialty training who have completed or are completing an internship and now need to demonstrate a broad foundation across the basic and clinical sciences underpinning eye care. The Arab Board Ophthalmology Part 1 study guide has 12 sections and about 2,632 words.
01Anatomy, Physiology and Embryology of the Eye
Know the layers of the cornea (epithelium, Bowman, stroma, Descemet, endothelium) and that the endothelium is neural-crest derived and non-regenerating in humans. Trace the aqueous pathway: ciliary epithelium → posterior chamber → pupil → anterior chamber → trabecular meshwork → Schlemm canal → collector channels → episcleral veins; the non-pigmented ciliary epithelium is the secretory layer.
277 words, about 1 min02Ocular Pharmacology and Therapeutics
Separate drug classes by mechanism: beta-blockers (timolol) reduce aqueous production; alpha-2 agonists (brimonidine) reduce production and increase uveoscleral outflow; carbonic anhydrase inhibitors reduce production; prostaglandin analogues (latanoprost) increase uveoscleral outflow; pilocarpine increases trabecular outflow. Know systemic side effects: beta-blockers cause bronchospasm and bradycardia; CAIs cause paraesthesia and metabolic acidosis; alpha-agonists cause fatigue and dry mouth.
219 words, about 1 min03Optics, Refraction and Clinical Optics
Master vergence, the thin-lens equation (1/f = 1/v − 1/u), and the relationship between dioptres and focal length. Understand emmetropia, myopia, hyperopia, astigmatism, and presbyopia.
229 words, about 1 min04Ocular Pathology and Microbiology
Know the basic categories of ocular pathology: inflammation, degeneration, dystrophy, neoplasia, and vascular disease. Understand the difference between hypertrophy, hyperplasia, metaplasia, and dysplasia.
235 words, about 1 min05Ocular Immunology and Inflammation
Understand the basic immune mechanisms: innate versus adaptive immunity, humoral versus cell-mediated responses, and the role of complement. Know the ocular immune privilege of the anterior chamber (ACAID) and the blood-ocular barrier.
222 words, about 1 min06Cornea and External Disease
Know the corneal layers and their diseases: epithelial (recurrent erosion, dry eye), stromal (keratoconus, dystrophies), endothelial (Fuchs). Understand the causes of red eye: conjunctivitis (viral, bacterial, allergic), keratitis, uveitis, acute angle closure, scleritis, and episcleritis.
192 words, under 1 min07Lens and Cataract
Know lens anatomy (capsule, cortex, nucleus) and the types of cataract: nuclear sclerotic, cortical, posterior subcapsular, and traumatic. Understand risk factors: age, diabetes, steroids, UV, trauma, smoking.
194 words, under 1 min08Glaucoma
Understand aqueous dynamics and the difference between open-angle and angle-closure glaucoma. Know that open-angle glaucoma is usually asymptomatic until late, while angle closure presents acutely with pain, halos, and a mid-dilated fixed pupil.
241 words, about 1 min09Retina and Vitreous
Know retinal anatomy: layers, macula, fovea, and the blood-retinal barrier. Understand common conditions: diabetic retinopathy (non-proliferative and proliferative), retinal vein occlusion, retinal detachment (rhegmatogenous, tractional, exudative), and age-related macular degeneration (dry and wet).
196 words, under 1 min10Uveitis and Intraocular Tumors
Classify uveitis by location (anterior, intermediate, posterior, panuveitis) and by course (acute, chronic, recurrent). Know common causes: HLA-B27, sarcoidosis, tuberculosis, toxoplasmosis, herpes viruses, and Behçet disease.
203 words, about 1 min11Neuro-Ophthalmology and Strabismus
Understand the afferent and efferent visual pathways. Know that optic neuritis causes painful visual loss with a relative afferent pupillary defect and dyschromatopsia; papilloedema is bilateral disc swelling from raised intracranial pressure.
220 words, about 1 min12Oculoplastics and Orbital Disease
Know eyelid anatomy (skin, orbicularis, tarsus, conjunctiva) and the lacrimal system. Understand common conditions: chalazion, hordeolum, blepharitis, ptosis, ectropion, entropion, and eyelid tumours (basal cell carcinoma most common; sebaceous carcinoma aggressive).
