The practicing ophthalmologist faces a common challenge on a daily basis: A patient's vision is worse than was expected, based on the appearances of the initial examination. Usually, a renewed and more careful examination explains the discrepancy. Often, however, additional examination finds nothing to explain the conflicting findings. Time is limited, and one is tempted to refer the patient to a neurologist or another ophthalmic service. The diagnostic modalities available at the next site often lead to an unguided attempt at diagnosis when it is felt that some sort of explanation for the visual loss must be found. This scenario can be both expensive and dangerous, subjecting the patient to a random wandering through neurodiagnostic procedures. At the end of this process, the patient is unsatisfied and anxiety ridden and returns to the ophthalmologist or seeks the counsel of other physicians or even alternative medicine practitioners. If the ophthalmologist wishes to find the correct diagnosis by the most efficient means, he/she must analyze the clinical findings carefully before referring the patient, to arrive systematically and rationally at a conclusive, problem-oriented working diagnosis.
