Abstract

Surgical excision in uveal tumors can be done via iridectomy, par- tial lamellar sclerouvectomy (PLSU), and endoresection. PLSU is employed in tumors involving the iridociliary, ciliary body, cili- ochoroidal and peripheral choroidal tumors. In PLSU surgery, a partial thickness scleral fl ap is dissected, the intraocular tumor is excised, and the fl ap is sutured back in position. PLSU surgery is done in iridociliary and ciliary body tumors with less than 3 clock hours of iris and ciliary body involvement and in choroidal tumors with a base diameter less than 15 mm. However, it can be employed in any size tumor for biopsy purposes. Endoresection is a relatively new technique whereby the intraocular tumor is ex- cised using vitrectomy techniques. The rationale for performing endoresection is based on the fact that irradiated uveal melano- mas may be associated with exudation, neovascular glaucoma, intraocular pigment and tumor dissemination and removing the dead tumor tissue may contribute to better visual outcome. There are some centers where endoresection is done without prior radi- otherapy. Allegedly, avoidance of radiation retinopathy and papil- lopathy are the main advantages of using endoresection without prior radiotherapy. PLSU, endoresection with or without prior external radiotherapy have similar vision, local recurrence, globe preservation, and metastasis rates compared to radiotherapeutic methods. PLSU and endoresection have become established as important surgical techniques that can be considered in the ma- nagement of intraocular tumors.

Özet

Göz içi tümörlerinde tümör eksizyonu; iridektomi, parsiyel la- meller sklerouvektomi (PLSU) ve endorezeksiyon yöntemleri kullanılarak yapılmaktadır. PLSU, iridosiliyer, siliyer, siliyoko- roid ve periferik koroidi tutan tümörlerde uygulanan bir cerrahi yöntemdir. Bu ameliyat için bir sklera fl ebi oluşturulur; tümör eksize edildikten sonra fl ep yerine sütüre edilir. PLSU ameliyatı, eksizyon amaçlı olarak üç saat kadranından daha az iris ve sili- yer cisim tutulumu yapan iridosiliyer/siliyer tömürler, ve taban çapı 15 mm’den büyük olmayan koroid tümörlerinde yapılabilir. Biopsi amaçlı olarak her büyüklükteki tümöre uygulanabilir. En- dorezeksiyon, vitrektomi yoluyla göz içi tümörünün eksizyonu esasına dayanan nisbeten yeni bir tekniktir. Endorezeksiyon ge- nellikle stereotaktik radyocerrahi sonrasında uygulanmaktadır. Radyoterapi sonrası göz içindeki ölü tümör dokusu neovasküler glokom, eksüdasyon, göz içine tümör ve pigment dispersiyonu gibi komplikasyonlara neden olabilir (toksik tümör sendromu). Ölü tümör dokusunun eksize edilmesinin bu hastalardaki gör- me prognozu üzerine olumlu etkileri bulunmaktadır. Endore- zeksiyon cerrahisini, radyasyon uygulamadan yapan merkezler de bulunmaktadır. Buradaki amaç ise, radyasyon makülopati ve papillopati gibi komplikasyonlardan da korunmaktır. PLSU, radyoterapi sonrası yapılan endorezeksiyon ve radyoterapisiz en- dorezeksiyon sonrasında plak radyoterapiyle karşılaştırıldığında benzer görme, lokal nüks, göz korunma ve metastaz oranları bil- dirilmektedir. PLSU ve endorezeksiyon cerrahileri, göz içi tümör- lerinin tedavisinde uygulanabilecek tedavi seçenekleri arasında yer almaktadır.
