Not from the same study unfortunately but these recent findings of visual deficits due to sleep deprivation :

strike me as similar, on first reading, to those found in ME/CFS (particularly with regards to tracking/smooth pursuit):

By using state-of-the-art eye movement research techniques, they were able to generate reliable effects showing trends of increasing impairment throughout the night for components of motion perception, such as smooth, continuous tracking eye movements (called pursuit), and effects on the small, episodic, jumping corrective eye movements (called saccades).
The researchers found that when participants were asked to track stimuli with unpredictable onset, direction, speed and starting location, human eye movements were dramatically impaired.

strike me as similar, on first reading, to those found in ME/CFS (particularly with regards to tracking/smooth pursuit):
Patients and controls exhibited similar error rates and saccade latencies (response times) on prosaccade and antisaccade tasks. Patients showed relatively intact ability to accurately fixate the target (prosaccades), but were impaired when required to focus accurately in a specific position opposite the target (antisaccades). Patients were most markedly impaired when required to direct their gaze as closely as possible to a smoothly moving target (smooth pursuit).
