Our findings demonstrate the safety and efficiency of Tissucol Duo as a conjunctival adhesive for pterygium autograft surgery as treatment of primary pterygium. Because of its fast and easy application, this product considerably reduces the time of surgery. Its use also avoids complications derived from sutures and diminishes the sensation of a foreign body in the eye following surgery.

Sterile endophthalmitis appears as an infrequent complication of intravitreal injections and seems to develop mainly in the context of the off-label use of drugs that have not been conceived for intravitreous administration. The aetiology of sterile endophthalmitis, independently of the administered drug, remains uncertain and a multifactorial origin cannot be discarded. Sterile inflammation secondary both to intravitreal triamcinolone acetonide and to intravitreal bevacizumab share many characteristics such as the acute and painless vision loss present in the big majority of the cases. Dense vitreous opacity is a common factor, while anterior segment inflammation appears to be mild to moderate. In eyes with sterile endophthalmitis, visual acuity improves progressively as the intraocular inflammation reduces without any specific treatment. If by any chance the ophthalmologist is not convinced by the sterile origin of the inflammation, this complication must be treated as an acute endophthalmitis because of the devastating visual prognosis of this intraocular infection in the absence of therapy.

With Densiron-68, high anatomical and functional success rates can be achieved with primary vitrectomy for RRD and predominantly inferior pathology.

The study suggests that intravitreal bevacizumab injection cannot prevent rebleeding in eyes undergoing pars plana vitrectomy for treatment of diabetic vitreous hemorrhage.

Aims To evaluate the recurrence rate of vitreous haemorrhage (VH) in patients treated with one intravitreal bevacizumab (IVB) injection (2.5 mg/0.1 ml) before planned pars plana vitrectomy for treatment of diabetic nonclearing VH. Methods Prospective pilot study of 32 eyes of 31 consecutive diabetic patients who underwent IVB injection within 1 week before surgery for persistent VH in the presence of active proliferative diabetic retinopathy. Three masked retinal specialists graded the amount of VH from grade 0 to grade 3 with slit-lamp biomicroscopy. Main outcome measures were the rate of recurrence of the VH, improvement in visual acuity, incidence of cataract formation, and postoperative complications through a followup of 6 months. Results The percentage of severe recurrent VH with no fundus details (grade 3) was 3% at 1 week follow-up and 3, 6, and 6% respectively at 1-, 3-, and 6-month follow-up. The mean best-corrected visual acuity (BCVA) improved from 1.6 (1/60) to 0.40 (6/15) logMAR (P ¼ 0.02) in 29 out of 32 eyes (91%). In all, 12 out of 22 (54%) phakic eyes developed cataract during the follow-up period, and 10 (31%) of them underwent cataract surgery. Conclusions Our study suggests that IVB injection few days before planned surgery seems to be efficacious and safe as an adjuvant treatment to prevent rebleeding in eyes undergoing pars plana vitrectomy for treatment of diabetic vitreous haemorrhage. IVB facilitates the surgery and reduces the need for extensive delamination and segmentation, decreasing the possibility of significant early active postoperative VH.

Intravitreal bevacizumab may be associated with an early growth of ERM in eyes with RVO, although a causative relationship cannot be established. Future randomised clinical trials are necessary to determine the efficacy and safety profile of this novel therapy.

Diabetic macular edema is one of the leading causes of visual loss in first world countries and the first cause in diabetic retinopathy. The Early Treatment Diabetic Retinopathy Study showed a significant benefit in using focal laser photocoagulation for the treatment of macular edema, more specifically defined as clinically significant macular edema. Nevertheless, progressive visual loss is found in the 26% of patients with diabetic macular edema treated with photocoagulation. The failure of laser treatment and the destructive nature of the therapy has forced researchers to pursue new alternatives including vitrectomy with or without internal limiting membrane peels, the use of proteinkinase C inhibitors, intravitreal injections of antibodies that inhibit the vascular endothelial growth factor, somatostatin analog, or the intravitreal injection with corticosteroids. Triamcinolone acetonide is glucocoticosteroid with antiangiogenic and antiedematous properties. Publications evaluating the safety and efficacy of intravitreal injection of triamcinolone in the treatment of diabetic macular edema show varying outcomes with respect to the increases of visual acuity and decreases in foveal thickness. Despite this, intravitreal triamcinolone is a treatment that has evolved quickly and is considered increasingly useful.
