25-Gauge Transconjunctival Sutureless Pars Plana Vitrectomy

Abstract

The TSV system was observed to be feasible, effective, and safe for a variety of vitre o retinal diseases. This minimally invasive and completely sutureless (transconjunctival) technique appears to decrease the convalescence period, operating time, and postoperative inflammatory response, and improve patient comfort.

Comparison of 25- and 23-gauge sutureless microincision vitrectomy surgery in the treatment of various vitreoretinal diseases

“…[3][4][5][6][7][8][9][10][11][12] Furthermore, a few recent reports continue to prove the superiority of MIVS in direct comparison with conventional 20-gauge vitrectomy. 6,7,[14][15][16][17] Although the makers of each of two commercially available small gauges, 25 and 23 gauges, claim to offer the safest and best product, no studies have yet compared the 25-and 23-guage systems.…”

“…Although a few studies have compared these minimally invasive MIVS approaches with conventional 20-gauge vitrectomy, 6,7,[14][15][16][17] no comparison between 25-and 23-gauge MIVS has yet been reported.…”

“…MIVS shortens operative time and facilitates postoperative recovery. [4][5][6][7][8][9][10][11][12] This 25-gauge sutureless system, however, was useful only in cases of relatively simple vitreoretinal pathology owing to limitations in cutter performance and a lack of necessary accessory instruments. In 2005, Eckardt developed 23-gauge sutureless vitrectomy using an obliquely entering trocar cannular system.…”

25-Gauge Transconjunctival Sutureless Vitrectomy for Idiopathic Macular Hole

“…Pars plana vitrektomi (PPV) ilk kez 1971 y›l›nda Machemer taraf›ndan uygulanm›flt›r (1) 25-G TSV'nin epiretinal membran ve makula deli¤i gibi vitreomaküler yüzey hastal›klar›, vitreus hemorajisi, proliferatif vitreoretinopatiyle komplike olmayan retina dekolman› ve yayg›n vitreus diseksiyonu gerektirmeyen traksiyonel diyabetik retina dekolman›nda uygulanabilece¤i bildirilmifltir (6)(7)(8)(9)(10). Biz de çal›flmam›zda, idiyopatik makula deli¤i tedavisinde 25-G TSV'nin etkinli¤ini ve güvenilirli¤i-ni araflt›rd›k.…”

“…Böylece konjonktivada skar geliflmesi engellenmekte ve gelecekte sa¤lam kalan konjonktivaya ihtiyaç duyulacak glokom cerrahisi gibi giriflimlere olanak sa¤lamaktad›r. Yine bu sistemde daha küçük skleral kesi olaca¤›ndan yara yerinin iyileflmesi de daha h›zl› olmaktad›r (6)(7)(8). Postoperatif konjonktival enjeksiyon ve a¤r›n›n daha az olmas›, hasta konforunun artmas›, erken postoperatif dönem astigmatizman›n olmamas›, konjonktiva diseksiyonu yap›lmad›¤›ndan limbal hücrelerin zarar görmemesi de TSV'nin avantajlar›ndand›r (6,(11)(12)(13).…”
