AUTOLOGOUS RETINA TRANSPLANTATION FOR TREATMENT OF REFRACTORY DOUBLE FULL-THICKNESS MACULAR HOLE IN ALPORT SYNDROME.

PURPOSE: To report the structural and functional outcomes of autologous neurosensory retinal transplantation for closure of refractory double full-thickness macular hole in a patient diagnosed with Alport syndrome.

METHODS

Patient with previous pars plana vitrectomy and a failed macular hole surgery (internal limiting membrane removal) underwent pars plana vitrectomy and autologous neurosensory retinal flap transplantation with silicone oil tamponade. Follow-up was performed after one year. The anatomic outcomes were evaluated mainly by fundus examination, optical coherence tomography (OCT), and microperimetry (MAIA). The functional changes were evaluated comparing best-corrected visual acuities preoperative and 1 year after surgery.

RESULTS

A 35-year-old man with progressive visual loss of two years of evolution presented a double full-thickness macular hole in the left eye. After retinal flap transplantation, the macular hole appeared successfully closed during the entire follow-up. Integration of both retinal flaps into the surrounding retina and regeneration of the external retinal layers were observed in optical coherence tomography. Best-corrected visual acuities improved from 20/200 preoperatively to 20/80 one-year postoperatively.

CONCLUSION

Pars plana vitrectomy combined with autologous neurosensory retinal flap transplantation is an effective option to achieve the anatomic closure of recurrent double full-thickness macular hole and significant visual recovery in Alport syndrome.
