Carline just went for an eye exam and the Dr. (a Neuro Opthalmologist) found that she cannot converge her eyes properly. (Imagine if you look at your outstretched finger at arms length. If you now bring the finger closer, you will look at the finger cross-eyed because both eyes must look at the finger simultaneously.) The ability to turn the eyes toward a target is the convergence and the Dr. told us that a PD symptom can be a reduction of the ability to turn in the eyes. This is called Convergence Insufficiency". It can be corrected by putting prisms in the eyeglasses. The correction will help, for instance, for reading and other close work. Just another PD symptom. K-F Etzold cg Carline (73/4)
