Visual training continues to be used as a remediation technique for reading disabilities despite consistent evidence that it does not provide effective treatment. A review of the ophthalmologic, optometric, and psychological literature relating to the assumption that a relationship exists between reading failure and perceptual ability has found no evidence to support this assumption.
Four children had benign, isolated, and recurrent sixth nerve palsies. Two of the children had palsies that occurred following immunizations. This had not been previously reported, to our knowledge. The other two patients had palsies that followed mild, febrile illnesses that were assumed to be of viral origin. In all patients the palsy resolved without other associated neurologic signs or symptoms. When a child has an atraumatic sixth nerve palsy, a tumor, hydrocephalus, and meningitis must be considered. If the neurologic examination shows no associated abnormalities, invasive testing is not indicated. The patient should be followed up closely by the ophthalmologist and pediatrician for spontaneous recovery.

A total of 15 eyes of 13 patients with lateral rectus palsies underwent Jensen procedures; one eye had a medial rectus recession and lateral rectus resection. It was arbitrarily decided to perform a Jensen procedure for patients with less than 40% normal abduction saccadic function. The patients' conditions were evaluated preoperatively and postoperatively by prism cover test. Versions, forced ductions, saccadic velocities, and diplopic field examinations were done. Postoperatively, all patients showed improved saccadic function; 12 of 13 patients acquired a functional range of diplopia-free vision; and 11 of 13 patients had aligned eyes with a good head position. By retrospective analysis we determined that the Jensen procedure gives good results for patients with severe lateral rectus palsy (less than 40% normal saccadic function).
Six patients are presented with ametropic amblyopia secondary to bilateral hypermetropia. Two patients had a strabismic amblyopia superimposed upon the ametropic amblyopia. All patients had a marked improvement in their visual acuity with the use of constant glass wear only. No associated ocular pathology was identified. It is the authors' belief that these patients are seen occasionally in general ophthalmologic practice. The diagnosis and treatment is straightforward; however, the diagnosis can be perplexing and unnecessary referrals and neuro-ophthalmologic investigation can ensue if this entity is not recognized.
