NCT04465188

Brief Summary

The purpose of this study is to determine whether a scleral buckling surgical procedure performed on fellow eyes of patients with genetically confirmed Stickler syndrome can prevent the occurrence retinal detachment and/or severe vision loss of the study eye.

    5 years

Secondary Outcomes (5)

  • Rate of retinal breaks

    5 years

  • Rate of intravitreal hemorrhage

    5 years

  • Effect of add-on cryotherapy

    5 years

  • Safety of the experimental procedure

    5 years

Study Arms (2)

Experimental arm

EXPERIMENTAL

Surgical procedure to prevent retinal detachment in the unaffected eye

Procedure: Encircling scleral buckle surgical procedure

Control arm

NO INTERVENTION

Standard procedure of clinical practice without any surgical procedure for the unaffected fellow eye.

Interventions

You may qualify if:

  • Genetically confirmed Stickler Syndrome
  • Aged 5 to 35
