Clinical Case:
No intraocular biopsy technique is free of risk and all have the possibility of giving false negatives due to the difficulty in obtaining a sufficient sample. A modified chorioretinal biopsy was performed on a patient with suspected choroidal melanoma after negative biopsy with 25G vitrectomy. In addition to removing a solid fragment of tumor material using bimanual surgery, material from the lesion was obtained with the vitreotome to perform cytology, which confirmed the diagnosis of melanoma.
Discussion:
Cytology obtained through the vitreotome in association with removing a solid sample of the choroidal lesion may improve the efficiency of intraocular biopsy.
