    CHANGES IN VESSEL-WALLS. NEW VESSELS IN VITEEOUS. Fig. 90.—Degenerative Change in Arterial Walls. Ann H., 43. BE. DravuTig made July 1889. Six months previously, in the eighth month of pregnancy, there was sudden loss of vision in the LE., followed by gradual partial recovery. She has had three similar attacks; the last, which occurred a month ago, was not followed by any improvement. In the LE. no definite opacity can be seen in the media, but there is only a faint fundus-reflex obtainable. V. LE. no p.l, EE. = Urine pale, acid. A well-marked cloud of albumen. Description.—Inferior temporal artery in part of its course converted into a white band of the width of the corresponding vein. In places, a thin blood stream is visible down the centre. A small vessel passing upwards and outwards is entirely white, and the inferior nasal artery is similarly affected on the disc. Two uniform-looking haemorrhages. No changes at the macula. Fig. 91.—New Vessels in the Vitreous. Frances C, 54. BE. Drawing made November 1889.—First seen June 3rd for recent failure of right eye, V. BE. = LE. = ^. There was a ha?morr]iage in the macular region, and a corresponding defect in the visual field, which was otherwise normal. Urine pale, cloudy, siJ. gr. 1022. Faint trace of albumen. Patient sutlers from headache, giddiness, and oedema of feet. On November 12th, V. BE. The ophthalmoscopic appearances depicted were discovered. Description.—Several of the retinal vessels have white lines accompanying them on either side, and some of the smaller ones appear as white bands. There are several small haemorrhages, one below, of a peculiar feather-like shape. A few soft white patches on the retina. Springing from the disc are numerous fine vessels. The majority of these lay in a plane anterior to the disc (2'0 D). Some appear to have at their distal extremities swellings of the same colour. Most of these latter were ill-defined, and had the appearance of haemorrhages, but the shape of others suggested that they were composed of the closely packed convolutions of a fine vessel. Subsequent History.—In January 1890 the vessels were accompanied by a thin gauze- like membrane which was sharply limited below, but shaded off gradually above. There was a smaller bundle of new vessels on the inner side of the disc. The vitreous soon afterwards became opaque. But in May 1892 it had partially cleared, and the fundus could be seen indistinctly. Upwards and inwards from the disc a brilliant white membrane could be seen with some vessels on it. It appeared to be too smooth for a detachment of the retina.
