Bilateral symmetrical tuberculous ulcers of the bulbar conjunctivae treated with streptomycin.

CLINICAL TYPES. (1)' Ulcerative type-characterised clinically by the presence of one or more miliary ulcers, which may or may not coalesce. They are usually found on the palpebral conjunctiva, rarely on the bulbar conjunctiva. (2) Nodular type-characterised by small greyish subcorjunctival nodules, which are very difficult to differentiate from trachomatous granules. (3) Hypertrophic papillary type-characterised by outgrowths of granulation tissue, which usually arise from the fornices, sometimes from the tarsal conjunctiva. Sometimes they become pedunculated and project on to the surface forming cock's-comb excrescences, which frequently show superficial ulceration. (4) Polypoid type-pedunculated tumours arising from the tarsal conjunctiva. (5) Tuberculoma-hard solid subconjunctival nodules in the bulbar conjunctiva, which do not undergo ulceration. The conjunctival epithelium remains intact, while the rest'of the conjunctiva remains normal.
