“…Indeed, a valve mechanism has been introduced in an attempt to prevent complications sometimes encountered with non-valved GDIs, such as hypotony, shallow anterior chamber, choroidal effusion and choroidal detachment [14]. Several studies have shown that AGV is safe and effective in reducing IOP in patients with primary [15][16][17], secondary [18][19][20][21][22][23][24] and refractory glaucoma [25][26][27]. However, the hypotensive efficacy of AGV in comparison with other anti-glaucoma interventions has not been completely elucidated.…”

The Ahmed glaucoma valve (AGV) is a popular glaucoma drainage implant used for the control of intraocular pressure in patients with glaucoma. While in the past AGV implantation was reserved for glaucoma patients poorly controlled after one or more filtration procedures, mounting evidence has recently encouraged its use as a primary surgery in selected cases. AGV has been demonstrated to be safe and effective in reducing intraocular pressure in patients with primary or secondary refractory glaucoma. Compared to other glaucoma surgeries, AGV implantation has shown favorable efficacy and safety. The aim of this article is to review the results of studies directly comparing AGV with other surgical procedures in patients with glaucoma.

“…Seton implantlarının, medikal tedavi ve filtran cerrahilere rağmen kontrol altına alınamayan olgularda GİB'i düşürmede etkili olduğu gösterilmiştir [3,8]. Seton cerrahisi sonrasında hifema, hipotoni, korneal ödem, tüp exposure, sığ ön kamara gibi çeşitli komplikasyonlar görülmektedir.…”

Amaç. Medikal tedavi ile kontrol altına alınamayan glokomlarda seton implantasyonu sonuçlarını değerlendirmek. Yöntem. Kliniğimizde, Ocak 2004-Ocak 2011 tarihleri arasında medikal tedaviyle kontrol altına alınamayıp seton implantasyonu yapılan 123 glokom hastasından, dosya bilgilerine ulaşılan ve düzenli takiplerine gelen 31 olgunun dosya bilgileri retrospektif olarak incelenmiştir. Bulgular. 24 olguya neovasküler glokom, 4 olguya üveitik glokom, 2 olguya afakik glokom, 1 olguya psödoeksfolyatif glokom tanısı ile seton implantasyonu yapılmıştır. 25 olguda Ahmed, 3 olguda Molteno, 2 olguda Baerveldt, 1 olguda Keiki Mehta implantı kullanılmıştır. Ameliyat öncesi göz içi basıncı ortanca değeri 40 mmHg (23-66) olarak bulunmuştur. Olguların takip sürelerinin ortanca değeri 10 ay (3-78) olarak saptanmıştır. Son kontroldeki GİB ortanca değeri 15,5 mmHg (6-67) olarak bulunmuştur. Ameliyat sonrası komplikasyonlar; 3 olguda kronik hifema, 1 olguda hifema ve hipotoni, bir olguda hipotoni ve sonrasında ftizis bulbi, 1 olguda ağrılı göz nedeni ile evisserasyon, 1 olguda epiretinal membran, 1 olguda lokalize endotelyal yetmezlik görülmüştür. Sonuç. Seton implantasyonu medikal tedaviye dirençli glokom olgularında etkili bir tedavi yöntemidir.Anahtar sözcükler: Glokom, seton implantları Abstract Aim. To evaluate our glaucoma tube implantation results for glaucoma cases that cannot be controlled with medication therapy. Method. The records of 31 cases whose medical records could be reached and and who could come to regular follow up visits among 123 patients that applied to our clinic between January 2004-January 2011 with refractory glaucoma for medical therapy were evaluated retrospectively. Results. Glaucoma tube implantation was performed with diagnosis of neovascular glaucoma in 24 cases, uveitic glaucoma in 4 cases, aphakic glaucoma in 2 cases, pseudoexfoliation glaucoma in 1 case. Ahmed valve for 25 cases, Molteno for 3 cases, Baerveldt for 2 cases, keiki mehta for one case were implanted. Preoperative intraocular pressure median value was 40 mmHg (23-66).The median value of follow up duration was found to be 10 months (3-78). The median value of intraocular pressures for last follow up visit was 15.5 mmHg (6-67). As postoperative complications, chronic hyphema in 3 cases, hypotony and hyphema in 1 case, hypotony and following phthisis bulbi in 1 case, painful eye and following evisceration in 1 case, epiretinal membrane in 1 case, endothelial failure in 1 case were observed. Conclusion. Glaucoma tube implantation is efficient alternative treatment method for refractory.

“…Ahmed glaucoma valve 5,6 is an established modality of management of advanced glaucoma cases withcumulative probability of successful outcome reported from different studies ranges from 76% to 87% at 1 year and 68% to 77% at 2 years [7][8][9] . Several early and late postoperative complications 3 have been reported in the literature including transient hypotony (19.5%), shallow anterior chamber (14.5%), tube blockage (11.3%), hemorrhage (7.2%),encapsulated bleb ( hypertensive phase)(10.9%), exposure of tube (5.0%), tube malposition (4.5%), corneal decompensation (2.3%),extrusion of implant (1.4%), and rarely endophthalmitis (1.7%) 4 .…”
