Purpose. To present initial experience with a novel biopsy method, the Essen biopsy forceps. Therefore, two patients with diagnostic suspicion of uveal melanoma underwent biopsy for histopathological confirmation. Case Presentation. Two patients presented with painless unilateral vision reduction. Ultrasound revealed the diagnostic suspicion of uveal melanoma. Therefore, biopsy with the Essen biopsy forceps using a sutureless 23-gauge three-port vitrectomy system was performed. The specimens were then submitted to a pathologist and processed. Histopathology of the obtained specimen confirmed the diagnostic suspicion of choroid melanoma in both patients. Conclusion. Essen biopsy forceps is a very practicable alternative method to the FNAB, allowing a combined histopathological and immunohistochemical examination for achieving high diagnostic accuracy at minimal risk.
