Ocular Motor Function	Clinical Findings	Literature
Smooth pursuit	Significantly reduced pursuit gain in elderly (66–87 y) compared with middle-aged (35–60 y)	Zackon and Sharpe⁶⁶
	Lower vertical tracking gain in elderly (70 ± 8 y) with increased phase lags for higher frequencies compared with younger (30 ± 6 y) subjects	Demer⁶⁷
	Lower tracking gain for predictable targets in the elderly (70 ± 8 y) with increased phase lags with increasing target stimuli Hz compared with younger (30 ± 6 y) subjects	Demer⁶⁷
Saccadic tracking	Peak eye velocities reduced in the elderly (66–87 y) to unpredictable targets	Sharpe and Zackon⁶⁸
	Latency and accuracy reduced for predictable and unpredictable targets in the elderly (66–87 y)	Sharpe and Zackon⁶⁸
	Frequency hypometric saccades in the elderly (66–87 y)	Sharpe and Zackon⁶⁸
	Increased latency and decreased peak eye velocity with advancing age (20–68 y)	Pitt and Rawles⁶⁹
Optokinetic	Reduced optokinetic gain for elderly (70 ± 8 years) with greater phase lag than younger (30 ± 6 y) group	Demer⁶⁷
