Is Tobrex a Good First-Line Antibiotic for Conjunctivitis?

Most conjunctivitis is due to viral disease, which will not respond to any antibiotic. Tobrex is a good, broad spectrum antibiotic which can be used to prevent secondary infection of the eye if that is a concern. For that purpose it is a good first line antibiotic since it is inexpensive and the production of resistant organisms is less of a serious problem than using more powerful antibiotics for this purpose.
