 behalf of the government declared,
 mAlthough extensive research has been devoted
 to glaucoma, very little is actually known
 about the disease, especial_[n_egarding its
 cause, prevention and cure. _I
 Spaeth notes, #[w]hat is known is that glaucoma causes damage to
 the optic nerve and can ultimately lead to blindness. "_-q/
 In the absence of conclusive evidence, uninhibited by a
 clear factual understanding of the disease process, opthamolo-
 gists are prone to speculate. Over the years they have advanced
 many, often inconsistent theories relating to the causes of
 glaucomas conjectured on _possible cures_ x and held many diverse
 opinions regarding the proper treatment of this disease. 43---I/
 Within the limited scope of current medical understanding there
 is only one fact upon which opthamologists are universally
 agreed: The only known way to stop progressive injury to the
 optic disk -- and thus prevent a further erosion of vision -_ is
 to reduce the patient's intraocular pressure. There is, for
 examples no conflict between ophthalmic witnesses who testified
 in this proceeding over the central importance of intraocular
 pressure reduction in the management and control of glaucoma°
