The effects of congenital nystagmus surgery.
Anderson-Kestenbaum operations for congenital nystagmus with severe head turn have been employed for the past 25 years. They have been documented as being effective in correcting head turns associated with congenital nystagmus. We have studied a group of patients with congenital nystagmus and head turn, both preoperatively and postoperatively, by means of recordings of eye movements. We have do...
متن کاملCongenital nystagmus surgery. A quantitative evaluation of the effects.
Nystagmus intensities at various gaze angles were studied both preoperatively and postoperatively, using accurate ocular motility recordings, in three cases of congenital nystagmus. In addition to shifting the nystagmus null, the surgery broadened the null region and resulted in an overall reduction in nystagmus intensity at all gaze angles. Surgical rotation also resulted in improved visual ac...
متن کاملEye Muscle Surgery for Acquired Forms of Nystagmus
We report 3 patients with acquired nystagmus who were treated with eye muscle tenotomy and reat tachment. The first patient had acquired pendular nystagmus (APN) associated with multiple sclerosis (MS) and underwent bilateral medial rectus tenoto mies and bilateral lateral rectus recessions to cor rect exotropia. Eye movements were recorded before surgery, after surgery, and after surgery an...
متن کاملThe Benefits of Extraocular Muscle Surgery in Infantile Nystagmus Syndrome
The following summary is written in response to the reports of patients whose physicians have made uninformed or erroneous comments to them regarding the efficacy of extraocular muscle (EOM) surgery for the improvement of visual function in patients with infantile nystagmus syndrome (INS). Also included are the results of studies demonstrating that the four-muscle tenotomy and reattachment (T&R...
متن کاملStudy of congenital nystagmus: optokinetic nystagmus.
A severe defect of optokinetic nystagmus (OKN) was found in 46 patients with congenital nystagmus. Abnormal patterns of OKN, such as superimposition of pendular oscillations on the optokinetic slow component and inversion of OKN, were observed. Optokinetic gain (eye movement velocity/drum velocity) was decreased compared to that in normal subjects, and optokinetic after-nystagmus, or transient ...
