AI Article Synopsis
- The study assessed the safety and effectiveness of injecting bevacizumab into silicone oil for treating iris neovascularization in diabetic patients post-vitrectomy.
- All treated eyes showed regression of neovascularization, with controlled intraocular pressure and visual improvement in most cases.
- Some recurrence of neovascularization occurred, but a second injection effectively managed it, suggesting the method is both safe and effective, warranting further research.
Article Abstract
Purpose: To evaluate the efficacy and safety of intrasilicone injection of bevacizumab for the treatment of iris neovascularization after vitrectomy for proliferative diabetic retinopathy.
Methods: Bevacizumab 1.25 mg/0.05 ml was injected into silicone oil in 15 eyes of 11 patients with iris neovascularization which had developed 2.5-6 months after vitrectomy and silicone oil tamponade. The main outcome measures were regression of iris neovascularization, intraocular pressure elevation, and visual acuity.
Results: In all eyes, iris neovascularization regressed and postinjection intraocular pressure was controlled within 7 days postinjection. Visual acuity improved in 12 eyes. In 4 patients, iris neovascularization recurred within 10 weeks after the injection and they were successfully treated with a second intrasilicone bevacizumab injection of the same dose.
Conclusion: Intrasilicone injection of bevacizumab is safe and effective in the treatment of patients with iris neovascularization after vitrectomy for advanced proliferative diabetic retinopathy. Further studies on greater numbers of patients and more advanced neovascularization are recommended.

Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic multisystem phakomatosis that can affect the skin, bones, and nervous system. NF1 typically presents with skin lesions, including freckles, café-au-lait macules, plexiform neurofibromas, and bony dysplasia, and is usually accompanied by a family history of the disorder. Ocular manifestations vary, but iris Lisch nodules and optic nerve gliomas are the most common features.

To our knowledge, this is the first report of anterior segment ischaemia after PreserFlo Micro-Shunt insertion surgery. Our patient developed anterior chamber (AC) activity and keratic precipitates 1 week after surgery. Five weeks after surgery, examination revealed a shallow AC, a distorted pupil with posterior synechiae and surface iris neovascularisation.

Article Synopsis
- - This study compares the outcomes of early versus delayed pars plana vitrectomy (PPV) in patients experiencing their first vitreous hemorrhage (VH) due to proliferative diabetic retinopathy (PDR) at Moorfields Eye Hospital from 2014 to 2016, excluding patients with specific eye conditions.
- - Patients were categorized into two groups: early PPV (within 6 weeks) and delayed PPV (after 6 weeks), with data collected on visual acuity and complications at baseline and 12 months post-surgery.
- - Results indicated that the early PPV group had significantly better visual acuity and fewer serious complications compared to the delayed group, highlighting the benefits of earlier intervention.

Introduction: Neovascularization of the lens is a rare entity linked to lens-induced inflammation due to many causes like trauma. We describe a case managed using suprachoroidal triamcinolone, an anti-VEGF injection, in conjunction with cataract surgery and IOL implantation.
Patient And Clinical Findings: A male patient, 27, presented with a severe reduction in vision in his right eye (RE) accompanied by redness for one month.
