NYSTAGMUS AND STRABISMUS

Drugs will assume a growing importance in the treatment of nystagmus a nd strabismic sensorial anomalies, but side effects should first be el iminated. New procedures have been proposed for abnormal head tilt in patients with nystagmus and inferior rectus complications. On the othe r hand, many classic procedures are reported to effectively manage inf erior oblique muscle overaction and dissociated vertical deviation (DV D). Unfortunately, little has been found in the current literature abo ut the action of these procedures on torsion. Association of DVD with vertical anatomical deviation (Brown's syndrome, ''A'' patterns, plagi ocephaly) gives rise to intriguing clinical pictures. Critical analysi s of the articles is increasingly arduous because it has been statisti cally demonstrated that 82% of the articles reviewed in three ophthalm ological journals presented statistical analysis using eight different methods.
