Posterior segment tumor resection is a procedure used to remove tumors from the posterior part of the eye, which includes the retina and choroid. This procedure is commonly performed for tumors such as choroidal melanoma, retinoblastoma, or metastases from other parts of the body.

During the surgery, the surgeon removes the tumor while taking care to minimize damage to the surrounding retina and other eye structures. In some cases, the eye may need to be reconstructed or a prosthesis may be used.

Posterior segment tumor resection is critical for preventing tumor spread, preserving vision, and managing the symptoms of ocular malignancies.
