iridocyclectomy
Pronunciation: eye-rid-oh-sigh-KLEK-toh-mee
Surgical procedure involving excision of iris and ciliary body tissue, typically for localized anterior uveal tumors.
Full Definition
Iridocyclectomy is a globe-preserving surgical technique that involves the complete excision of affected iris and ciliary body segments, primarily used for treating localized anterior uveal melanomas and other iris or ciliary body tumors. The procedure aims to achieve complete tumor removal while preserving the eye and maintaining useful vision when possible. Surgical planning requires careful assessment of tumor extent, typically measured in clock hours, and may involve partial or complete iridectomy combined with ciliary body resection. Potential complications include hypotony, cataract formation, and corneal decompensation. Patient selection is critical, as tumors exceeding certain size parameters or those with extensive circumferential involvement may be better managed with alternative treatments such as enucleation or radiotherapy.
Usage
Usage note: Document extent of resection in clock hours and specify margin status in surgical reports.
