This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1903 edition. Excerpt: ... a positive differentiation. The disease is rare. Symptoms.--i. Congestion of the conjunctival vessels is hidden by the plastic membrane in severe cases.

Pain is generally of an itching, burning character, but when there is great swelling of the lid there is an added sensation of pressure on the ball. 3. Discharge is at first serous and flaky, and may be tinged with a little blood. As soon as the membrane begins to soften the discharge becomes purulent. 4.

Vision is affected as in purulent conjunctivitis (page 96). 6. Ulceration of the cornea is produced as in purulent conjunctivitis (page 96). In croupous conjunctivitis it rarely happens but in diphtheritic conjunctivitis, if severe, it is almost inevitable. 7. The membrane in mild cases is limited to the palpebral conjunctiva and can be wiped off leaving a slightly bleeding surface. In severe cases it covers the entire conjunctiva and can only be removed by force, leaving a raw surface. 8. Constitutional Symptoms will only be present when the disease is diphtheritic.
