Normal intraocular pressure during enucleation for choroidal melanoma.
A simple surgical technique for maintaining normal intraocular pressure during enucleation of eyes with a malignant melanoma of the choroid consists of making an incision into the anterior chamber through clear cornea with a microvitreo-retinal blade, followed by the introduction of a No. 21-gauge scalp vein needle or a No. 23-gauge sidewall-holed needle attached to a closed system filled with balanced salt solution. Measurements of pressure fluctuations during five enucleations are given. Such a system maintains the anterior chamber and keeps fluctuations in IOP to a minimum. This may be important in preventing hematogenous dissemination of tumor cells, resulting in metastatic disease.
