Papillae and follicles

PARTS OF CONJUNCTIVA-

• Palpebral-
• Marginal
• Tarsal
• Orbital
• Fornix
• Bulbar
• Limbal

MICROSCOPIC-

1. EPITHELIUM

• Palpebral conj- 2 layers of epith
• Intermarginal strip-Transitional stratified squamous epith
• From fornix to limbus-4-6 layers
• Limbus- stratified epith

2. SUB-EPITHELIAL / ADENOID LAYER-

Loose connective tissue + leukocytes

C . FIBROUS LAYER

FOLLICLES-

Localised aggregation of lymphocytes in the subepithelial adenoid layer.
CAUSES-

• HSV conjunctivitis
• molluscum contagiosum c’vitis
• chlamydial infection
• Parinaud’s oculoglandular syndrome

Q Diff bet trachomatous follicles & follicles in follicular conjunctivitis?

Ans

- Trachomatous follicles- 5mm dia
-Commence in lower fornix
-Form a row along upper tarsal margin
-Undergo cicatrisation & form minute 

-Stellate scars.

PAPILLAE-

Hyperplasia of central Vs surrounded by diffuse infiltrates of lymphocytes,plasma cells & eosinophils
CAUSES-

• Chronic blepharitis
• Vernal catarrh
• Giant papillary conjunctivitis
• contact lens induced
• Superior limbic keratoconjunctivitis

CONJUNCTIVAL CONGESTION	CILIARY CONGESTION
Bright red	Dull red
Near the fornix	Around the limbus
Branch dichotomously	Branch radially
Arise from post conj Vs	Arise from anterior ciliary Vs
Phenylephrine→ blanch	Do not blanch
Vs fill up from the fornix	Vs fill up from the limbus
Superficial inv-c’vitis, simple hyperaemia	Deep inv-iritis, scleritis

TRUE PTERYGIUM	PSEUDOPTERYGIUM
Degenerative	Inflammatory
Usually progressive	Stationary
