conditions may be determined by placing the index finger 

 of the right hand upon the upper lid of the left eye and the 

 index finger of the left hand upon the upper lid of the right 

 eye; then compare the tension or hardness of one eye with 

 the other by palpating with the tips of the fingers; in in- 

 creased hardness, firm pressure of the finger tip produces no 

 impression; but the tension may be doubtful unless there is 

 a marked difference in the impressions made upon the two 

 eyes. The pupil is generally greatly expanded and the lens, 

 as a rule, remains transparent, but m.iy in rare instances be 

 opaque. The depth of the anterior part of the aqueous 

 chamber is diminished ; the front surface of the iris is almost 

 in contact with the internal surface of the cornea. The iris 

 in some cases appears swollen and it is sluggish in movement 

 or entirely inactive. The slight diffuse cloudiness of the 

 cornea and the aqueous humor produces the sea green (glau- 

 coma) color of the pupil. The episcleral and conjunctival 

 vessels are more or less congested. But the excavation or 

 sinking or depression of the optic nerve can not be seen 

 without the aid of an opthalmoscope; this cupping of the 

 optic disc is due to the intraocular pressure ; the cup is called 

 the glaucomatous cup and the yellow halo around it is known 

 as the glaucomatous ring. 



Treatment consists in preventing inflammatory adhesions 

 between th& ms and cornea by using eserine. Also, reduce 

 inflammation if the iris, ciliary bodies and choroid, that 

 may lead to glaucoma; this may be accomplished by using 

 hot or cold water fomentations. A well developed case can 

 only be relieved by irodectomy. If eserine is used con- 

 stantly it must be in a weak solution (1-10 to l-16th grain 

 to one ounce of water.) Irodectomy consists in removing a 

 portion of the iris; in glaucoma one-fifth to one-fourth of 

 the iris should be removed; or what is known as the broad 

 peripheral irodectomy can be done only by a skilled surgeon.
