Any other information on results incl. tables

All rabbits displayed slight injection of the conjunctival blood vessels one hour after instillation of 0.1 g Bisphenol-M. At the 24-hour examination two animals were showing slight corneal opacity over less than one-quarter of the cornea and a crimson-red appearance

to the conjunctivae. Similar changes were present in both cases at the 48 and 72-hour examinations, but had completely resolved by Day 9. All ocular changes had resolved in the third animal by Day.3.
