Surgical outcome for cyclic strabismus
Reviewed by Fiona Rowe

The aim of this study was to report the outcome of surgical treatment in a series of seven cases of paediatric cyclic strabismus. This was a retrospective study of children with surgical treatment for the manifest cyclic deviation. Six children had cyclic esotropia and one had cyclic esotropia with vertical deviation. There were four males and three females. Age at presentation was a mean of 4.42 ±3.69 years (range 1-12 years). Mean esotropia angle was 36.4 ±14.9PD (range 20-60) for near and 32.1 ±6.9PD (range 20-40) for distance. Mean follow-up was 18.4 ±5.5 months. Duration of strabismus prior to surgery was 11.1 ±9.4 months (range 3-29). All children had a 48-hour cycle and surgery was based on the maximum angle on the strabismus day. Best corrected visual acuity was 0.0/0.1 logMAR and general ophthalmic examination was normal. On straight days, there was positive binocular vision. Postoperatively, all cases were orthophoric and this was maintained over the follow-up period. The authors found surgical treatment to be the most effective management plan in the long-term.
