title: [Cyclotropia and surgical treatment after macular translocation].
abstract: OBJECTIVE
  Macular translocation is a new surgical treatment method successfully performed in recent years in cases of age-related macula degeneration. Cyclotropia and associated orthoptic problems may occur after macular translocations. The aim of our study was to present the application and results of various external eye muscle surgery techniques to eliminate cyclodeviation after macular translocation.
  
  
  METHODS
  Between January 2001 and April 2001, 15 patients underwent macular translocation. After an average of 47 days counterrotation was applied to these patients to eliminate incyclotropia formed due to macular translocation. In 8 cases, superior and inferior oblique muscle surgery was combined with opposite vertical transpositions of the horizontal recti. In 5 cases, full tendon transposition of the superior oblique muscle to the nasal part of the globe was combined with the anterior margin advancement of the inferior oblique muscle. In 2 cases, only combined surgery of superior and inferior oblique muscles was performed. The degree of cyclodeviation was measured by both objective and subjective methods before and after counterrotation. Mean follow-up period was 53.9 days.
  
  
  RESULTS
  The average objective cyclodeviation formed after macular translocation was 29.6 degrees. Combined surgery of superior and inferior oblique muscles led to a mean excyclorotation of 15 degrees whereas combined oblique muscle surgery performed with vertical transposition of horizontal recti provided a mean excylorotation of 20.8 degrees. The most effective method was the combination of total nasal transposition of superior oblique muscle with the anterior margin advancement of the inferior oblique muscle resulting in an improvement by 33 degrees.
  
  
  CONCLUSIONS
  Macular translocations cause cyclodeviation. The ensuing cyclotropia can be eliminated by various surgical techniques of external eye muscles according to the degree of cyclotropia.
