LXfl. On the Staphyloma, Hydrophthalmia, and Carcinoma 

 of the Eye. By James Ware, £^9., F.R.S. and Vice 

 President of the Medical Society. 



[Continued from p. 304.] 



i- NEXT proceed to consider the disorder called Hydro- 

 phthalmia. By this term authors do not in general mean 

 an accumulation merely of the aqueous humour, but so great 

 an enlargement of the whole eye/produced by an increase 

 of the vitreous humour as well as the aqueous, as to cause 

 the eye to occupy an undue portion of the orbit, and to 

 occasion difficulty and pain when the eyelids are closed over 

 it. Thus defined, it may perhaps with more propriety be 

 denominated Exophihaimia than Hydrophthalmia*. In 

 describing this disorder, a greater discrimination is required 

 than seemed necessary in the former part of this paper. In 

 the sta|ihylom3, for instance, the opake projecting cornea 

 designates the nature of the disorder in so plain a manner, 

 that it seems impossible to make a mistake with regard to 

 its nature. But in the hydrophthalmia, which implies aa 

 universal enlargement of the eye, some examination is re- 

 quisite in order to ascertain what occasions the enlargement : 

 whether there be an equal enlargement of all the different 

 parts of the eye ; a morbid enlargement of one particular 

 part only ; the formation of an adventitious body within 

 the eye ; or a projection of the eye in consequence of a 

 substance formed behind it. 



Scarpa is of opinion that an accumulation of water between the choroid 

 coat and retina is a common cause ot tlie hydropiithalniia, and he minutely 

 de^cribes a case of this kind wliich ocrurjt d in a child three years and a half 

 old, invvhich the eye was a third iarj^er than its natural size, the cornea 

 partalcinf; of the increase, in the same proportion as the sclerotica. I have 

 several tune? observed, on disscctinj,' ihc eye after death, that there has been 

 an eft used fluid between the choroid coat and retina, the vitreous hmnour 

 bein;^ wholly absorbed, and (he retina collapsed into a cylindrical, or rather 

 a Conical, chord like substance, its apex arising frjm the optic nerve, and its 

 basis sui rounding the crystalline humour ; but, though this elTusiori had pro- 

 duccd a fixed dil.i'aiion of the pupil, an opacity of the crystalline, and somc- 

 tniits a vi(,li;iit dc. p-scated pain in the eye, 1 have never known it to occakiun 

 an ftalargeinent of this or^au.
