No great treatment. Ocular dysmetria is a type of dysmetria that involves the under- or over-shooting of the eyes when attempting to re-fixate gaze on something. This is usually from problems in the cerebellum of the brain, and can be seen with multiple sclerosis. Isoniazid and Clonazepam have been used to treat dysmetria. There is no surgical or ocular procedure that helps this. Nor can glasses.
