SURGICAL OUTCOMES OF VASOPROLIFERATIVE TUMORS REFRACTORY TO NONINVASIVE THERAPIES

Introdução / Purpose

To evaluate the outcomes of surgical treatment of refractory vasoproliferative retinal tumors (VPTs) and its complications.

Material e Método / Methods

Clinical charts of all patients diagnosed with VPTs who underwent surgical treatment from 2005 to 2020 were reviewed. Clinical features, surgical techniques and outcomes were evaluated.

Resultados / Results

From 25 eyes of 23 patients with VPTs, 17 eyes (68%) underwent surgical intervention to treat tumor activity and associated complications including epiretinal membrane (n=10, 59%), retinal detachment (n=8, 47%) and vitreous hemorrhage (n=3, 18%). All eyes underwent pars plana vitrectomy (PPV) with endolaser/cryotherapy to control tumor activity and to treat associated complications. Three cases required tumor resection. At the end of follow-up (mean 55.4 months, range 2 – 305 months), no eye presented tumor activity, nor retinal detachment after one or two surgeries. There was no epiretinal membrane recurrence. The mean baseline best-corrected visual acuity (BCVA) was 1.2 ± 0.7 logMAR and the mean final BCVA was 0.7 ± 0.6 logMAR (p<0,05). BCVA improved two or more lines in 12 eyes (70.5%) at the end of follow-up.

Discussão e Conclusões / Conclusion

In this series of patients with large active VPTs, surgical intervention allowed control of tumor activity in all patients and provided overall satisfactory anatomic and functional outcomes.
