Recurrent retinal detachment in Stickler Syndrome

Area of Science:

• Ophthalmology
• Genetics
• Retinal Diseases

Background:

• Stickler Syndrome is a genetic disorder associated with an increased risk of retinal detachment.
• Understanding recurrence patterns is crucial for managing visual outcomes in these patients.

Purpose of the Study:

• To investigate the clinical factors contributing to recurrent retinal detachment (RD) in patients diagnosed with Stickler Syndrome.
• To characterize the specific features and timing of recurrence following initial RD repair.

Main Methods:

• A retrospective case series was conducted on patients with Stickler Syndrome who underwent surgical repair for rhegmatogenous retinal detachment.
• Recurrent RD was classified as 'early' (within 1 year) or 'late' (after 1 year) post-initial surgery.

Main Results:

• Recurrent RD occurred in 46% of eyes treated with pars plana vitrectomy/scleral buckling (PPV/SB) and 63% treated with primary scleral buckling (SB).
• Early recurrences were primarily associated with proliferative vitreoretinopathy (PVR), while late recurrences often resulted from new retinal breaks.
• Eyes with recurrent RD had poorer visual acuity compared to those without recurrence.

Conclusions:

• Early recurrent RD in Stickler Syndrome is predominantly driven by PVR.
• Late recurrent RD is frequently caused by the development of new retinal breaks, sometimes posterior to surgical intervention sites.
• Patients undergoing primary SB for rhegmatogenous RD remain at significant risk for late re-detachment, necessitating vigilant monitoring.
