Purpose: To evaluate PCPV during vitrectomy on the treatment of posterior pole tumors. Methods: Two choroidal melanomas that refused radiotherapy and enucleation, one choroidal hemangioma and a Von Hippel hemangioma were included. All cases except one melanoma had serous retinal detachment (RD). In cases with RD the purpose was to reattach the retina and apply laser to the tumor. In a large melanoma without RD 8mm high and 4.5 mm base, the end point was to excise the tumor. Results: One choroidal hemangioma with complete serous retinal detachment (RD) and a Von Hippel hemnagioma with RD were treated. One melanoma without RD was excised by the use of vitrectomy probe. One melanoma with serous RD was treated by endolaser fotocoagulation with 810 nm laser previous indocianine green IV injection. Vitreous was removed by PCPV in all cases, a rapid retinal reattachment was observed in eyes with RD. Vitreous cavity was isolated during vitrectomy and melanoma excision. Vitrectomy probe was useful to remove the melanoma, to perform retinectomy and choroidal tumor excision. Vitreous cavity was maintained clear from blood when the melanoma was removed. Follow–up was of 6 months at minimum. All eyes treated with laser had an attached retina and involution of the tumor. The eye in which the melanoma was removed had a useful vision with an attached retina at 8 months follow–up. Eyes with melanoma had no metastasis up to the last visit. ICG–IV injection along with 810 nm laser was applied in the treatment of melanoma. 50cc to 150 cc of PCL were used in each case. Conclusions:PCPV is an alternative method to treat tumors from the posterior pole. It maintains an isolated and a clear vitreous cavity during vitreous removal, endolaser treatment and tumor excision..
