In 48 children with cerebral palsy the characteristics of the squint and amblyopia were analyzed, also with respect to the features of cerebral palsy and to birth weight. Strabismus of congenital esotropia type was found to be common, as was also exotropia of early onset. Spontaneous alternation or an accommodative component of the squint was present only(More)

On the basis of the patients' history, recurrencies, and clinical and fluorescein angiographic features, it was suspected that the disorder was of(More)

The condition called “lactation optic neuritis” has been previously considered a clinical entity of its own.

The course of the disorder was(More)
A 14-year-old boy had an acute attack of measles while on cytotoxic chemotherapy for a testicular neoplasm. Two months later a fatal measles encephalopathy developed, verified by histological, ultrastructural, and immunofluorescent studies. Ophthalmoscopy showed progression of flat depigmented areas of the retina as well as prominent lesions mimicking(More)
Fifteen patients suffering from serpiginous choroiditis were followed up for 1 to 10 years (mean 4.9 years). There were 7 women and 8 men with ages ranging from 20 to 65 years (mean 35 years). In 13 patients both eyes were involved. Ten of the 15 patients had both inactive scars and fresh lesions when first seen. The individual lesions resolved in a few(More)
In a family consisting of 8 surviving siblings, pseudoxanthoma elasticum was diagnosed in 4 sisters. One of them had a severe visual handicap, and another a slight decrease of the visual acuity because of the ocular lesions. The other 2 sisters also had fundal lesions, but they were visually symptom-free. Great variation was also found in the appearance of(More)
