ABSTRACT
The prognosis for spontaneous improvement of Brown's syndrome has not yet been clarified. The present longitudinal long-term study comprised 10 patients with idiopathic Brown's syndrome arising or noticed during the first or second year of life. They were followed for an average of 13 years during which each had a mean of 9 examinations. Spontaneous improvement occurred in 9 of the patients, 3 of whom were cured, obtaining normal motility. All three cases had initially been permanent and monolateral, with initially mild, moderate, and severe restriction, respectively. In the remaining 6 patients who changed for the better, the spontaneous improvement consisted of a reduction of the initial hypotropia and the initial depression of the adducted eye. When the patients were last seen, the sensorial state of binocular vision demonstrated in 4 of the 10 normal binocularity, in 2 binocularity corresponding to microstrabismus, and in 4 alternating suppression.

An epidemiological study of amblyopia was performed among old people without previous screening and treatment. The study revealed a prevalence of 2.9% (strabismic in 2.3%, anisometropic in 0.6%). Present residual amblyopia among Danish school children is about 1% according to literature. The rate of cure of amblyopia by the present Danish system of prophylaxis and treatment is estimated to be 60-70%.

Ten years post-operative follow-up of 25 consecutive patients with intermittent exotropia have been performed. 13/25 patients are at follow-up fine, that is small and symptom-free exoforia, good sensorial binocular functions of normal type, sufficient although subnormal fusional amplitude and never exotropia. 8/25 patients are fair, that is only occasionally momentary occurrence of exotropia and binocular complaints. 4/25 patients are orthoptically poor (suppression on all tests), but without complaints. Eye position is on a whole unchanged for distance, whereas exodeviation has increased about 10 PD for near during the 10 years post-operative observation time (no orthoptic treatment in this period). 22/25 patients indicated spontaneously at the follow-up examination that they considered their squint cured. None of the patients had cosmetic or functional restrictions in jobs or studies.
