Tafel Xl.VIf. Fig. 104. A. G.. aet. 20 years, a labourer's daughter, belongs to a very healtiiy family. According to her own account her sight has been weak from birth. Right Eye; V. =-/(so: no improvement possible with glasses, but objectively there is M. = 5 D; reads Nieden VI with difficulty. Slight Strabismus divergens et sursum vergens. Left Eye: V-^/ao without correction: M.-5D; reads Nieden V. with difficulty. In both eyes the peripheral field of vision is normal, and no central scotoma can be made out. Only in the i-ight eye a crescent- shaped scotoma corresponding to the choroidal patch is present on the temporal side between IS** and 28. Right and Left: Microphthalmos of slight degi-ee. Cornea: vertical diameter 10 mm, horizontal 9 mm; sliglit Corectopia to the nasal side. From the lesser circle of the iris a light greyish-white ridge or crest rises round the pupil, it is low and yet projects distinctly into the anterior chamber in a slanting direction, and presents in one or two places oval recesses and openings. In the right eye alone a very short thread springs from the upper and inner border of the ridge. In neither eye does the ridge keep to the small circle of the iris in the lower and inner quadrant, but separated from it by a distance of about 4 mm. it passes into two curved spurs which disappear behind the lower and inner corneo-scleral margin. The pupillary zone of the iris and the part of it not covered by the crest present no peculiarity either in pattern or colour. The scleral border appears to project a short distance into the cornea with jagged glistening processes. Media normal. Right Eye: The optic disc appears somewhat enlarged and slightly angular in shape. The centre of it is entirely devoid of vessels, and presents a pit in whicli no details can be observed. Between the edge <of this pit and that of the papilla there is a narrow rose-pink ring composed of the optic fibres. With the exception of the superior nasal vein which appears to come forward close under the upper margin of the disc, all the retinal vessels emerge at the edge of the pit, having already split into lateral branches without any visible connection with a main vessel. The arteries take a normal straight course, but the two upper and lower veins which are of normal size describe numerous tortuosities. Only one single tiny
