The present invention contemplates a topical ophthalmic
system for treating a
Gram-positive bacterially-infected
mammalian eye. The
system comprises an ophthalmic composition containing a halogenated
fluorescein or a pharmaceutically acceptable salt or ester thereof dissolved or dispersed in an aqueous ophthalmic carrier and present in an anti-bacterial
keratitis-treating effective concentration of about 0.2 μg / mL to about 50 μg / mL. The ophthalmic composition has a pH value of about 6.5 to about 7.6, a
viscosity of about 10 to about 300 cps and an osmolality of about 270 mOsm / kg to about 340 mOsm / kg. The ophthalmic composition is present in a vessel opaque to actinic light. Also contemplated is a method of treating a
mammal having a
Gram-positive bacterial infection of an eye by administering the ophthalmic composition to the infected eye and maintaining the treated eye in the substantial absence of actinic light for about 3 hours to about 12 hours.
