[The significance of the phenomenon of dynamic disadaptation scotoma in the early diagnosis of macular dystrophies].
Examinations of 202 patients (337 eyes) with different forms of macular dystrophies, such as idiopathic flat detachment of the retina in the macular area, central sclerotic dystrophy of the retina, tapetoretinal macular degeneration, outcome of local inflammation of pigmented epithelium, post-traumatic central chorioretinitis, etc., allowed to receive data confirming high information value of a method based on the phenomenon of dynamic scotoma of disadaptation as compared with examinations on the Amsler's grid and campimetry. Thus, metamorphopsias were revealed on the Amsler's grid in 193 eyes (57%), changes by means of campimetry--in 171 eyes (51%), while dynamic scotoma disadaptation was revealed in 337 eyes (100%). The method is most effective at early stages of the disease because it allows to reveal it in the presence of high visual acuity and negative data of the Amsler's grid and campimetry.
