Abstract
Streptococci were isolated in 18 of a series of 520 cases of inflammation of the eye and adnexa. Streptococcus hemolyticus, Streptococcus viridans, or Streptococcus nonhemolyticus was recovered in pure culture in 9 cases but in the others, other bacteria were also present. The virulence was variable. The location, symptoms, and clinical course are discussed. Three types of streptococcal conjunctivitis, i.e., pseudomembranous, lacrimal, and acute conjunctivitis associated with some skin disease, are reported; a fourth type, occuring in the newborn, is referred to in the literature. Streptococcus is an infrequent cause of conjunctivitis. The organism is not an epithelial parasite, apparently growing in subepithelial tissues in two cases, and in the remainder, multiplying in the conjunctival secretions and producing a conjunctivitis by action of exotoxins.
