23-gauge transconjunctival vitrectomy for posterior segment intraocular foreign bodies

BACKGROUND: This study is a report of the outcomes of 23-gauge (G) transconjunctival vitrectomy (TV) performed to treat a posterior segment intraocular foreign body (IOFB).
METHODS: The data of 14 eyes of 14 patients who underwent 23-G TV for the removal of a posterior segment IOFB were reviewed in this study. Surgery was initiated with a 23-G system in each case and the posterior segment IOFB was removed through the enlarged sclerotomy site. All of the patients were male. The mean age of the patients was 36.6±11.0 years.
RESULTS: The foreign body (FB) was located in the vitreous in 11 eyes and in the retina in 3 eyes. Before the 23-G TV, complicated cataract was detected in 6 eyes, vitreous hemorrhage was detected in 5 eyes, and retinal detachment was detected in 1 eye. The size of the FB ranged from 3 mm to 7 mm; 12 of the FBs were metallic and 2 were glass. Silicone oil was used as a tamponade agent in 5 eyes and gas tamponade (C3F8) was used in 4 eyes. The mean follow-up time was 8.15±2.9 months. At the last examination, of the 14 eyes included in the study, the visual acuity (VA) was 0.1 or better in 10 eyes and less than 0.1 in 4 eyes because 2 eyes had peri-macular scar, 1 eye had massive sub-epiretinal membrane and 1 eye had retinal re-detachment.
CONCLUSION: 23-G TV is seen as an effective and minimally invasive technique to remove posterior segment IOFBs.

Göz içi arka segment yabancý cisimlerinin yönetiminde 23-gauge transkonjonktival vitrektomi

AMAÇ: Göz içi arka segment yabancý cisimlerinin (GÝASYC) yönetiminde 23-gauge (G) transkonjonktival vitrektomi (TV) sonuçlarýnýn bildirilmesi amaçlanmýþtýr.
GEREÇ VE YÖNTEM: Bu çalýþmada GÝASYC nedeniyle 23-G TV uygulanan 14 hastanýn 14 gözü incelendi. Tüm olgularda cerrahiye 23-G sistem kullanýlarak baþlandý ve GÝASYC’ler geniþletilmiþ sklerotomilerden çýkartýldý. Çalýþmadaki tüm olgular erkek olup, ortalama yaþ 36.6±11.0 yýldý.
BULGULAR: Yabancý cisim 11 olguda vitreus içerisindeyken, üç olguda retina içindeydi. 23-G TV cerrahisi öncesinde, altý hastada komplike katarakt, beþ hastada vitreus içi kanama ve bir olguda retina dekolmaný tespit edildi. On ikisi metalik ve ikisi cam tipinde olan yabancý cisimlerin boyutlarý 3 mm ile 7 mm arasýnda deðiþmekteydi. Cerrahi tamponat olarak, beþ olguda silikon yaðý kullanýlýrken dört olguda gaz tamponat (C3F8) kullanýldý. Cerrahi sonrasý ortalama takip süresi 8.15±2.9 aydý. Son muayenede, çalýþmaya dahil edilen 14 gözün 10’unda görme keskinliði (GK) 0.1 veya üzerindeyken, dört gözde 0.1’in altýndaydý ki bunlardan ikisinde perimaküler skar, birinde yoðun sub-epiretinal membran ve birinde nüks retina dekolmaný mevcuttu.
TARTIÞMA: Göz içi arka segment yabancý cisimlerinin çýkarýlmasýnda 23-G TV etkin ve minimal invaziv bir yöntem olarak görünmektedir.
