Electrochemical lysis at the stage of endoresection for large posterior intraocular tumors

By Yu. A. Belyy, A. V. Tereshchenko, A. V. Shatskih and D. K. Solovyov


<p><strong>Purpose</strong>: to design the new combined technique of endoresection with intraoperative intraocular electrochemical lysis at the tumor destruction stage for large posterior intraocular tumors.<br /><strong>Methods</strong>: 3 patients (3 eyes) with large choroidal melanomas t3N0M0 (tumor thickness — 8-10 mm, base diameter — 13-15 mm, juxtapapillary localization). Mean age was 55.4 years old. Endoresection with intraoperational intraocular electrochemical lysis of the tumor was performed. Electrochemical lysis was performed with use of the technical unit ECU 300 (Soering, Germany) and the original method of combined intratumoral positioning of two platinum electrodes: anode and cathode.<br /><strong>Results</strong>: the tumor was removal completely in all 3 cases. the anatomical retinal reattachment was reached in all patients. Sclera was safe in all 3 cases. Visual acuity was not changed (NLP). At the place of the removal tumor a surgical choroidal coloboma without pigmentation all over scleral bed and periphery was shown in all cases in distant postoperative period (from 1.5 to 3 years). No local recurrences or metastasis were revealed in all patients.<br /><strong>Conclusion</strong>: Further investigations in clinical group are necessarily to determinate the real possibilities of the combined method and the indications for endoresection with intraoperative intraocular electrochemical lysis for large intraocular tumors.</p><p> </p
