The symptoms described suggest that the Colonel may have suffered a left-sided stroke which could have affected his right visual field resulting in a condition called left homonymous hemianopsia. This means that the left half of his visual field is affected and objects on his left side may be invisible to him. A diagnosis of glaucoma or presbyopia does not explain the specific symptoms mentioned, and hemi-inattention would not typically be diagnosed by an ophthalmologist.
