Slide 1: Anatomy of the Conjunctiva • Definition: A thin, vascular, transparent mucous membrane covering the anterior sclera and lining the eyelids. • Parts of Conjunctiva: • Palpebral Conjunctiva: Lines the inner surface of the eyelids. • Bulbar Conjunctiva: Covers the anterior sclera (white of the eye). • Fornix Conjunctiva: The transition zone forming a cul-de-sac between eyelids and globe. • Histology: Non-keratinized stratified columnar epithelium containing Goblet cells (secretes mucin). Slide 2: Physiology & Functions of Conjunctiva • Protection: Acts as a physical and immunological barrier against foreign bodies and pathogens (contains MALT - Mucosa-Associated Lymphoid Tissue). • Lubrication: Goblet cells secrete the mucin layer of the tear film, preventing eye dryness. • Mobility: Allows smooth and independent movement of the eyeball. Slide 3: Common Pathologies of Conjunctiva • Conjunctivitis (Pink Eye): Inflammation caused by bacterial, viral, or allergic agents. • Subconjunctival Hemorrhage: Broken blood vessels causing a bright red spot on the sclera (harmless, self-limiting). • Pterygium & Pinguecula: Non-cancerous growths linked to chronic UV light and wind exposure With photos of disess .

This overview covers conjunctival anatomy, detailing the palpebral, bulbar, and fornix regions, and their relation to the sclera and Tenon’s capsule. It explores the conjunctiva's functions, including MALT-mediated protection and the role of goblet cells in mucin lubrication, alongside the mechanics of tear film layers and blinking. Additionally, it addresses conjunctival diseases, comparing conditions like conjunctivitis, hemorrhage, and pterygium, while linking symptoms to potential causes...
