Khurana Indu Khurana is a cornerstone textbook in ophthalmic education, widely used by postgraduate students and residents to build a fundamental understanding of ocular structures and functions. Amazon.com Core Content & Organization The book is structured into 14 chapters
- 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.
- Ocular anatomy: globe, orbit, adnexa
- Extraocular muscles and innervation
- Eyelids, lacrimal apparatus, conjunctiva
- Cornea, sclera, uveal tract (iris, ciliary body, choroid)
- Lens structure and accommodation
- Retina: layers, photoreceptors, visual pathway
- Aqueous humor dynamics and intraocular pressure
- Electrophysiology and basic visual physiology
- Common clinical correlations and examination basics

Anatomy and Physiology of the Eye
2. External & Protective Structures
Orbit & Ocular Adnexa
- Bony Orbit: Pyramidal cavity protecting the globe; contains fat, vessels, nerves, and extraocular muscles.
- Eyelids (Palpebrae): Protect from trauma/light; distribute tear film. Layers: skin, muscle (orbicularis oculi, levator palpebrae superioris), tarsal plate, conjunctiva.
- Conjunctiva: Transparent mucous membrane covering sclera (bulbar) and lining lids (palpebral); contains goblet cells for mucus secretion.
- Lacrimal Apparatus: Lacrimal gland (tear secretion) → puncta → canaliculi → lacrimal sac → nasolacrimal duct. Tears provide lubrication, nutrition, and antibacterial action (lysozyme).
