A patient who presents with recent onset diplopia can be a cause of concern. It is possible a patient with a PSC cataract could experience diplopia. A good way to differentiate PSC as the cause of diplopia from a potential pathological cause is by utilizing case history and your occluder.

A patient with diplopia due to a PSC will likely experience the diplopia at both distance and near viewing. In addition, when covering the “non problematic” eye, the diplopia will still be present. In contrast, a patient with a potential pathological cause of recent onset diplopia may only experience diplopia at distance or near, and the diplopia may resolve by simply covering either of the eyes. It is crucial to obtain a good case history in helping you determine whether or not recent onset diplopa could be a very dangerous situation.
