title: Visual complications of Stickler syndrome in paediatric patients with Robin sequence.
abstract: BACKGROUND
  The most frequent diagnosis in patients with syndromic Pierre Robin sequence is Stickler syndrome, which may be complicated by congenital high myopia and substantial risk of retinal detachment. However, cases of Stickler syndrome with probable visual complications are rarely identified among this group of patients by members of the cleft team. This study was designed to determine the prevalence of Stickler syndrome among the author's group of patients with Robin sequence, and to investigate the visual outcome among paediatric patients with Robin sequence and Stickler syndrome.
  
  
  METHODS
  Eight children (six male and two female) with Stickler syndrome and Robin sequence were referred to be followed up every 6 months in the Ophthalmologic Department because of high myopia at less than 10 years of age. Three patients came from the author's study group and five were referred by other cleft surgeons. They were examined with repeat ophthalmic and indirect fundus examinations including cycloplegic refraction, and slit lamp biomicroscope examinations. Laser photocoagulation (2 cases) treatment for retinal degeneration or operation (3 cases) for retinal detachment was performed once evidence of significant ophthalmologic finding was noted.
  
  
  RESULTS
  Of the 91 cases of newborns with isolated cleft palate treated by the first author, eight patients had Robin sequence, and among these, three had Stickler syndrome. The prevalence of Stickler syndrome among this subgroup of patients was 37.5% (3/8). Among these three patients and the additional five referred by other cleft surgeons, the average spherical equivalents of the first cycloplegic refraction for the 16 eyes was -12.39+/-2.72 diopter (D) (range -8.75 to -18.5D). Of the eight patients, five did not need any therapy, two children had retinal degeneration in the left eye and retinal detachment in the right eye while one child had retinal detachment in the right eye only. Laser photocoagulation was performed in the two left eyes with retinal degeneration and was successful. Surgery was performed on the three eyes with retinal detachment, one was successful while two failed and the patients developed total blindness at ages four and six respectively. Out of these three children with retinal complications, only one child remained free of visual deterioration in both eyes during the follow-up period.
  
  
  CONCLUSIONS
  Early identification of Stickler syndrome in children with Robin sequence by cleft surgeons is necessary to insure early referral to an ophthalmologist for detection of myopia, monitoring for retinal detachment, and prevention of visual complications.
