A study has been performed testing the relative bursting strength of sclera in rabbits treated with diathermy, cryotherapy, or ruby laser energy. Neither the cryotherapy nor laser appeared to weaken the strength of sclera, whereas the diathermy appeared to cause an appreciable loss of scleral bursting strength.
