Web1 de mar. de 2024 · The eye movement pattern, sometimes referred to as a waveform, can be classified into different categories and there are at least 12 different types of nystagmus waveforms according to a classification study (Hussain, 2016; Theodorou & Clement, 2016; Dell’Osso & Daroff, 1975 ). WebThe Nystagmus waveforms are generated according to the rough existing Nystagmus classification. The pendular Nystagmuses are modelled by a sinusoidal signal and the jerks are modelled by quadratic slow phases and linear quick phases.
