⚡ TL;DR(Too Long; Didn't Read)

Conclusion: Satisfactory anatomic and functional results can be achieved by using bimanual lee hnique and inhibiting neovascularisation in severe PDR patients, whom surgery was avoided and accepted as unsuccessful in recent years because of heavy bleeding and retinal tears.

Abstract

Objectives: To evaluate the anatomic and functional results of pars plana vitrectomy performed with bimanual technique following intravitreal bevacizumab injection in florid type severe PDR patients with intense neovascular vessel and membrane formation. Methods: 14 eyes of 10 patients, in a group of 7 females and 3 males whose ages ranged from 23 and 54, presenting intense neovascular vessel and membrane; formation with various degrees of intravitreal haemorrhage were studied. 1.25 mg of 0.05ml bevacizumab injections were performed 3-7 days before surgery. 6 of the 12 phakic eyes were performed fakoemulsification and IOL implantation in the bag just before the surgery. PPV was performed using three-port vitrectomy approach and membranes were peeled with the help of twinlight chan - delier by the bimanual technique. Following aggressive endophotocoagulation, intraocular tampon was inserted(5 eyes C3F8/9 eyes silicone oil). Palients were followed up for at least 3 months Results: 7 patients had preoperative visual acuity of hand movement. 4 patients had a visual acuily of linger counting from 1 meter, 1 patient had a visualacuity of finger counting from 3 meters and 2 palients had a visual acuiy of 1/10 respectively. 10 of the patients had a visual acuity measured 5/200 or better afler the surgery. (Patients with a pre-operative visual acuity of hand movement were 3/7, and patients with a better visual acuily were 7/7). Anatomic success was achieved in all cases. The cause of failure in palients whom visual acuity did not improve after surgery was attributed to optic atrophy and unfunclionality of large vessels. One of the patients suffered from aggressive rubeosis iridis and neovascular glaucoma postoperatively. Conclusion: Satisfactory anatomic and functional results can be achieved by using bimanual lee hnique and inhibiting neovascularisation in severe PDR patients, whom surgery was avoided and accepted as unsuccessful in recent years because of heavy bleeding and retinal tears.

Özet

Amaç: Yoğun neovasküler damar ve membranları bulunan florid karakterdeki ağır proliferatif diyabetik retinopatili olgularında intravitreal bevacizumab enjeksiyonunu takiben bimanuel teknikle yapılan pars plana vitrektomicerrahisinin anatomik ve fonksiyonel sonuçlarını irdelemek. Yöntem:Yaşları 23 ile 54 arasında değişen, yoğun neovasküler damarlar ve membranlar yanında değişik miklarlarda VİH gösteren, 7'si kadın, 3'ü erkek 10 diyabetli olgunun 14 gözü çalışmaya alındı. Olgulara cerrahiden 3-7 gün önce 1.25mg 0.05 ml intravitreal bevacizumab enjeksiyonu uygulandı.Fakik 12 gözden 6'sına cerrahinin başında fakoemülsifikasyon ve in the bag GIL uygulandı. 3'lü girişimle PPV yapılıp; membranlar bir twinlight chandelier varlığında bimanuel teknikle soyuldu. Agresif endolotokoagülasyonu takiben bir göz içi tamponu yerleştirildi (5 göz C3T8 / 9 göz silikon yağı). Olgular en az 3 ay takip edildi. Bulgular: Cerrahi öncesi gözlerden 7'si EH , 4'ü 1 mps, biri 3 mps ve ikisi 1/10 görme keskinliğine sahipli. Cerrahi sonrasında gözlerden lO'u 5/200 ya da daha iyi bir görme seviyesine sahip oldu (Başlangıçta görme seviyesi EH olan gözlerde 3/7, EH'den daha iyi olan gözlerde 7/7). Tüm olgularda anatomik başarı sağlandı, Görme seviyesi artmayan olgularda başlıca neden optik atrofi ve büyük damarların fonksiyon göremez durumda oluşuydu. 1 olguda ise cerrahiden bir süre sonra agresif bir rubeozis ve neovasküler glokom gelişli. Sonuç: Daha önceki yıllarda ağır kanamalar ve retina yırtıkları nedeniyle başarısız olduğumuz ve cerrahi uygulamaktan kaçındığımız pek çok ileri PDR'li olguda ncovaskülarizasyonun baskılanması ve bimanuel tetkik sayesinde tatminkar anatomik ve fonksiyonel sonuçlara ulaşılabilmekledir.
