Abstract
Background. The majority of cases of exotropia with extreme deviations (30- 45 degrees or 60-90 prism dioptres) are secondary forms of strabismus, eith er consecutive, following monolateral combined recession/resection procedur es in childhood, extreme anisometropia or following trauma. For the surgica l treatment the deviation is often too great to be corrected completely by conventional repositioning of the medial and lateral rectus muscle of the a ffected eye and patients justifiably refuse an operation even on the main e ye because the indications are mostly more aesthetic than functional. Methods. The paper presents a technique of a free mucosa transplant. The ef fect can be strengthened and made more secure following repositioning of th e muscle. Results. With this method even extreme deviations (up to 45 degrees corresp onding to 90 prism dioptres) could be successfully and permanently correcte d by surgery on the deviated one eye only. Conclusions. This method provides a new option for patients who are often i ncorrectly told that their deviation cannot be corrected by monolateral sur gery.
