GIANT PAPILLARY CONJUNCTIVITIS (GPC)

Giant papillary conjunctivitis is the inflammation of conjunctiva with formation of very large sized papillae.

Etiology. It is a localised allergic response to a physically rough or deposited surface (contact lens, prosthesis, left out nylon sutures). Probably it is

Atopic keratoconjunctivitis (AKC)

Atopic  keratoconjunctivitis (AKC) can be thought of as an adult equivalent of vernal keratoconjunctivitis and is often associated with atopic dermatitis. Most of the patients are young atopic adults, with male predominance.

Symptoms include:

• Itching, soreness, dry sensation.
• Mucoid discharge.
• Photophobia or blurred vision.

Signs

• Lid margins are chronically inflamed with

VIRAL CONJUNCTIVITIS

Most of the viral infections tend to affect the epithelium, both of the conjunctiva and cornea, so, the typical viral lesion is a 'keratoconjunctivitis'. In some viral infections, conjunctival involvement is more prominent (e.g., pharyngo-conjunctival fever), while in others cornea is more involved (e.g., herpes simplex).

Viral infections of conjunctiva include:

• Adenovirus conjunctivitis
• Herpes simplex keratoconjunctivitis
• Herpes zoster conjunctivitis
• Pox virus conjunctivitis
• Myxovirus conjunctivitis
• Paramyxovirus conjunctivitis
• ARBOR virus conjunctivitis

Clinical presentations. Acute viral conjunctivitis may
