We report ophthalmological findings in 15 cases of nephropathia epidemica. The patients, 13 men and 2 women, were 20 to 62 (mean 30) years of age. The onset of the disease was characterized by high fever, nausea, headache, abdominal pain, backache, somnolence, red throat, proteinuria, and oliguria. The symptoms subsided rapidly during the polyuria stage. Transitory myopia occurred in 8 patients (53%). Conjunctival injection and haemorrhages were seen in 3 patients (20%). One patient had acute glaucoma with oedema in the cornea and shallowing of the anterior chamber, with subsequent anterior uveitis and haemorrhages in the ocular fundus, and another patient had acute glaucoma. Three patients had photophobia which occurred in 2 patients without any glaucoma or anterior uveitis.
