Accommodative fluctuations in Adie's syndrome.
Recent reports suggest that the higher frequency components (around 2 Hz) of accommodative fluctuations may arise from the accommodative 'plant' and may have no role in the control of the accommodation system. The dynamic responses of accommodation in two cases with Adie's syndrome were recorded. The results showed that the velocity of accommodative responses was reduced, and the accommodative fluctuations in the higher frequency components were completely diminished. It can be concluded that the origin of fast fluctuations is not located at a more peripheral site than the lesion of tonic accommodation. Since the possible lesion exists at the ciliary ganglion, the origin of the fast oscillation may not be the accommodative 'plant', but the neural one.
