Abstract: High speed and small gauge vitrectomy systems have made surgical intervention in complications of diabetic retinopathy (DR) safer. The availability of anti-vascular endothelial growth factor (anti-VEGF) compounds for use in DR has significantly improved intraoperative and postoperative outcomes. This review discusses the indications for surgical intervention in DR. The role of anti-VEGF compounds is discussed as surgical adjuvants with an emphasis on timing of treatment before surgery.

Abstract: Deep anterior lamellar keratoplasty (DALK) is preferred over conventional penetrating keratoplasty (PKP) for the treatment of anterior corneal opacities or ectasias due to decreased risk of endothelial rejection. However, DALK remains surgically challenging, largely due to challenges associated with achieving consistent pneumo-dissection of posterior stroma from the underlying pre-Descemet’s or Descemet’s membrane (DM). Air must be injected at sufficient depth in the corneal stroma in order to achieve successful pneumo-dissection, but advancing a needle too deep into the cornea can lead to perforation of DM. We describe here a novel technique using a handheld slit lamp (Eidolon model 510L, Eidolon Optical LLC, Natick, MA, USA) to assist in creation of the big-bubble in DALK surgery. Use of a handheld slit beam intraoperatively is a safe, relatively inexpensive, and effective technique for increasing the success of big-bubble formation in DALK procedures.

Abstract: Diabetic retinopathy (DR) is a complex multifactorial disease and one of the leading causes of visual impairment worldwide. DR pathogenesis is still not completely understood and, even if studies performed in the past focused on microvascular dysfunction as the main event, growing body of scientific evidence has demonstrated an important role of inflammation and neurodegeneration in the onset and progression of DR. This review summarizes current literature on the role of inflammation in the pathogenesis and progression of DR. In particular, it focuses on clinical inflammatory biomarkers detectable with non-invasive retinal imaging, suggestive of a local inflammatory condition. Current available treatments are applicable only at advanced stages of disease, therefore, there is the need to detect biomarkers of subclinical or early DR that can help in DR management before irreversible damage occurs. A better understanding of inflammatory pathways involved in DR may permit to implement more specific and personalized therapeutic strategies and clinical biomarkers may be a helpful tool in the everyday clinical practice to direct the patient to the most appropriate treatment option.

Abstract: Despite appropriate management of the systemic disease, patients with diabetes may develop severe forms of diabetic retinopathy that require surgery. Non-clearing vitreous haemorrhage (VH), traction retinal detachment involving the macula, combined traction and rhegmatogenous retinal detachment, progressive fibrovascular proliferation (PFP) and rubeosis with acute VH represent the main indications for surgery. Vitrectomy techniques and surgical tools have developed dramatically in the last decade in order to help the surgeon succeed in these challenging cases.

Abstract: The Handan Offspring Myopia Study (HOMS) is the first offspring eye study in a Chinese population. The study design is based on another representative study, Handan Eye Study. In this study, we found 1 diopter (D) of generational myopic shift, a weak protective effect of the outdoor activity on myopia, and a modest protective effect of the eye exercises of acupoints on myopia, among the rural children in the northern area.
