Section 3: The Ocular Adnexa (Supporting Structures)
No study of anatomy is complete without the supporting cast: ak khurana anatomy and physiology of eye pdf
- The Orbit: Boundaries, fissures, and foramina (superior orbital fissure, optic canal). This is critical for understanding cranial nerve palsies.
- Extraocular Muscles (EOMs): Origins, insertions, actions, and nerve supply (CN III, IV, VI). The PDF usually includes a handy table for the "Laws of Ocular Motility" (Sherrington’s and Hering’s law).
- The Eyelids and Lacrimal System: Anatomy of the tear film (lipid, aqueous, mucin layers) and the physiology of tear drainage.

Why This Book Remains the Gold Standard
The human eye is a masterpiece of biological engineering. Standard anatomy books often give it a chapter or two. Khurana’s book, however, dedicates an entire volume to the subject, offering depth that general textbooks cannot match. and errors of refraction (myopia
Section B: Physiology of the Eye
This section explains "how" the eye works. It transforms the anatomical structures into functional mechanisms.
- Physiology of Vision: How light is converted into electrical impulses (phototransduction).
- Optics: Basic principles of physical optics, refraction, and errors of refraction (myopia, hypermetropia, astigmatism).
- Accommodation: The mechanism by which the eye focuses on near objects.
- Pupillary Reflexes: The anatomy behind the direct and consensual light reflex.
- Intraocular Pressure (IOP): The dynamics of aqueous humor production and drainage, which is fundamental to understanding glaucoma.
- Ocular Motility: How the extraocular muscles work together for binocular vision.
