[Acute blindness due to trauma in a Welsh pony-colt].

A healthy, 10-day-old Welsh A pony colt was totally blind 1 day after arrival at a studfarm. Both eyes appeared normal on external inspection. The young animal had been very distressed during the 40-km journey to the studfarm. Intravenous corticosteroids were administered for 2 days, but did not result in any observable improvement. The animal was euthanized at the owner's request. Both eyes with the optic nerves were removed for histological examination. Both optic nerves showed Wallerian degeneration, a well-known response of peripheral nerves to trauma. The foal, which was not tethered during transportation, probably sustained a blunt trauma in the trailer. This case highlights the importance of taking adequate measures to prevent young animals from sustaining blunt trauma during transport.

[Chondroma in a sheep].

A chondroma localized in the last two ribs at one-third of the distance from the spinous process to the sternum, and approximately 35 cm in diameter, is reported. The ewe was about four to five years of age and in fairly good condition. Apparently it was a rare case; a condition of this type was not previously reported in the Netherlands. Only two cases of chondrosarcoma (also in the costal arch) out of 129,981 autopsies are reported (1).
