Use of autologous fascia lata as a natural biomaterial for tectonic support in surgically induced necrotizing scleritis.

BACKGROUND

Surgically induced scleral necrosis (SINS) is a severe form of scleritis threatening both vision and integrity of the eye. SINS is a rare sequel of ocular surgery and has been described after cataract extraction, trabeculectomy, strabismus, retinal detachment surgery including parsplana vitrectomy, penetrating keratoplasty, pterygium excision, and diode cyclophotocoagulation.

MATERIALS AND

METHODS

To report on the application of autologous fascia lata as a readily available natural biomaterial for ocular tectonic support in SINS, we performed this retrospective chart review including two eyes of two patients; one case following both repaired rupture globe, parsplana vitrectomy, and diode laser transscleral cyclophotocoagulation and one case following pterygium surgical excision.

RESULTS

Successful coverage of the area of scleral thinning with autologous fascia lata was achieved in both cases with overlying healthy vascularized conjunctiva and resolution of the ocular inflammation.

CONCLUSION

The fascia lata transplant combined with systemic immunosuppression was successful in providing adequate tectonic support and controlling the progression of scleral melt for two cases with SINS.
