Not illustrated. 1896 edition. Excerpt: ...in the part non-vascularised does not become pigmented, and at the margin of the patch there is often an excess of pigmentation. These patches of failure in the differentiation of the choroid give rise to what are known as colobomata. They occur, of course, most frequently in the region of the foetal ocular cleft, but may be met with, as pointed out by Lindsay Johnson r, in any part of the fundus.

CAsEs OF GLAUCOMA IN WHICH THE INCREASE OF TENSION IS DIFFICULT TO EXPLAIN. THE pathology of glaucoma may not inaptly be compared to a large child s puzzle with many pieces of various and irregular shapes. Its framework has by the united efforts of many earnest workers been pieced together. Several important centre pieces, however, have yet to be added to make the picture complete. Some of these have probably been placed wrongly; every additional bit, however small, rightly inserted may, by forming some fresh curve or notch, suggest how the centre pieces should lie. I propose now to deal with some of these small bits, the shape and situation of which I have carefully studied. Of all the theories which have been put forward to explain the increase of tension in glaucoma, that which attributes it to the obstruction to the exit of the aqueous humour from the eye, and which has been so ably expounded and supported by Mr. Priestley Smith, is the most fascinating and apparently explains best the...
