Eye movements were recorded by a modified technique of electro-oculography in 11 alert patients during binocular patching, monocular patching, and no patching. Quantitative analysis of the frequency and amplitude of eye movements revealed a statistically significant decrease in both parameters during binocular patching as compared to no patching. Binocular patching decreased the frequency of eye movements by a mean of 44% and decreased the amplitude by 20%. Monocular patching did not decrease the frequency or amplitude to a significant degree.

Horizontal fixational shifts were present during all patching conditions, but were less frequent during binocular patching. Periodic vertical conjugate eye movements were observed only during binocular patching. The clinical impression that binocular patching decreases eye movements in the alert patient was substantiated.
