Comparison of Medpor coated tear drainage tube versus silicon tear drainage tube in conjunctivodacryocystorhinostomy: problems and solutions.

Purpose: This study aims at comparing two different types of drainage tubes in conjunctivodacryocystorhinostomy, which are used for upper lacrimal system obstruction or damage, with respect to their respective postoperative problems and solutions.

Methods: Nineteen eyes of 17 patients who underwent conjunctivodacryocystorhinostomy (CDCR) or conjunctivorhinostomy (CR) surgery with a Medpor coated tear drainage tube or silicon tube placement between October, 2010, and February, 2014, were included in this retrospective comparative study.

Results: In the initial surgery, Medpor coated tear drainage tubes were used in 11 eyes by CDCR, whereas silicon tear drainage tubes were implanted into 2 eyes by CR and 6 eyes by CDCR.

Results of intravitreal triamcinolone acetonide in patients with macular edema secondary to branch retinal vein occlusion.

Background: Macular edema is one of the most common causes of visual loss in patients with retinal vein oclusions. Intravitreal corticosteroids and intravitreal anti-vascular endothelial growth factors are modalities of treatment for macular edema secondary to branch retinal vein occlusion (BRVO).

Objective: To present the results of intravitreal triamcinolone acetonide therapy in patients with macular edema secondary to BRVO.

Effect of Bevacizumab Injection before Vitrectomy on Intravitreal Hemorrhage in Pseudophakic Patients with Proliferative Diabetic Retinopathy.

We evaluated the effect of intravitreal bevacizumab (IVB) injection before pars plana vitrectomy (PPV) on intravitreal hemorrhage (VH) during and after vitrectomy for postoperative the first day and the first month in pseudophakic patients with proliferative diabetic retinopathy (PDR). This retrospective study was performed on 44 eyes of 44 patients who underwent vitrectomy for PDR. Patients were divided into PPV (n = 22 eyes) and PPV + IVB (n = 22 eyes) groups.
