[Circular figures surrounding the macula of patients with albinism in chromato-ophthalmoscopic examination with transformed light].
Examination of the fundus oculi in redfree polarized light carried out in 19 patients (12 with albinism and 7 with albinotic type of fundus oculi) have revealed for the first time peculiar ringlike figures. Since there is no evidence that these figures are formed by retinal folds, the authors suppose that it may be the result from light wave interference. Light waves of the fundus oculi may be reflected not only by the internal limiting membrane but also by Bruch's membrane. These waves overlapping each other form a figure identical to Newton's interference rings, since the thickness of the retina is increasing from the foveola towards the periphery. The ringlike figure in the center of the fundus oculi may be regarded as an additional clinical signs of albinisms of the fundus oculi.
