REVIEW
Michael W Stewart
INTRODUCTION: Laser photocoagulation has been the standard treatment for diabetic macular edema (DME) and proliferative diabetic retinopathy (PDR) for several decades. The discovery of vascular endothelial growth factor (VEGF) and the subsequent determination of its critical role in the development DME and PDR has led to the development of VEGF inhibitory drugs. Ranibizumab was the first anti-VEGF drug approved for the treatment of both DME and diabetic retinopathy in eyes with DME. METHODS: Medline searches with the keywords "ranibizumab," "diabetic macular edema," and "proliferative diabetic retinopathy" were performed to identify pertinent pre-clinical studies and clinical trials...

REVIEW
Yujia Zhou, Ahmad A Aref
Selective laser trabeculoplasty (SLT) has been widely used in the clinical management of glaucoma, both as primary and adjunctive treatment. As new evidence continues to arise, we review the current literature in terms of indications and efficacy, surgical technique, postoperative care, repeatability, and complications of this therapy. SLT has been shown to be effective in various glaucomas, including primary open-angle glaucoma (POAG), normal-tension glaucoma (NTG), steroid-induced glaucoma, pseudoexfoliation glaucoma (PXFG), and primary angle-closure glaucoma (PACG), as well as other glaucoma subtypes...

A 10-year-old male was referred for evaluation of a right orbital mass present for 3 weeks with associated tenderness to palpation. Magnetic resonance imaging (MRI) and computed tomography imaging (CT) revealed a solid mass centered in the frontal bone with extension into the orbit. Surgical excision and histologic analysis of the lesion was consistent with a diagnosis of a Giant Cell Tumor (GCT) of the frontal bone. The patient tolerated the procedure without complication and is doing well upon follow-up.

REVIEW
H Burkhard Dick, Tim Schultz
The use of femtosecond laser surgery improves the precision and reproducibility of corneal incisions and the capsular opening; it also reduces the amount of ultrasound energy required for lens nucleus work-up. The rate of complications reported so far appears to be low. There are a number of contraindications such as a history of cornea and/or glaucoma surgery and certain anatomical features like deep-set eyes, kyphosis, tremor, and obesity. Visual recovery and refractive results of both techniques are excellent...

REVIEW
Daniel Su, Jean-Pierre Hubschman
The role of retinal photocoagulation as a first line therapy for various retinal pathologies has decreased with the introduction of anti-vascular endothelial growth factor therapy. However, retinal laser therapy remains an important treatment modality, especially with the emergence of micropulse subthreshold treatment and the integration of newer technology such as augmented reality and semi-automated delivery. This review summarizes current evidence for micropulse laser as a treatment modality and discusses the role of new technology such as augmented reality in the future of laser therapy...

Sameh M Fouda, Hala K Mattout
INTRODUCTION: Laser in situ keratomelieusis (LASIK) is one of the commonest refractive procedures performed nowadays. The dry eye problem is nearly universal in all patients after LASIK and it can be so annoying that the post-operative patient satisfaction is sometimes precluded. Conventional treatment includes the use of artificial tears. Alternative methods such as punctal plugs and botulinum toxin injection can be used for the management of post-LASIK dry eye. The aim of this study is to compare botulinum toxin injection in the orbicularis muscle to lacrimal punctal plugs for the control of post-LASIK dry eye manifestations...

INTRODUCTION: Vernal keratoconjunctivis (VKC) is a severe form of pediatric ocular allergy, characterized by acute and chronic corneoconjunctival inflammation that may lead to visual sequelae. Although topical immunosuppressive drugs such as cyclosporine are usually effective, some severe forms may be refractory and require prolonged steroid therapy. Very few papers report the use of omalizumab in VKC in the literature. In the present study, we describe our clinical experience with omalizumab in severe VKC children...

Evaporative dry eye has gained increasing interest in recent years in academia, pharmaceutical, and medical device industries. The main cause of this type of dry eye is attributed to meibomian gland dysfunction (MGD). MGD is a diffuse abnormality of the meibomian glands characterised by terminal duct obstruction and eventually leading to signs and symptoms of dry eye. There have been only a few reported animal models of MGD, but recent advances are likely to lead to new models and better ways to assess the pathology in these animals...

Mohammed Ali Khan, Julia A Haller
Pharmacologic vitreolysis with ocriplasmin, a 27 kilodalton serine protease, is an effective nonsurgical treatment option for vitreomacular traction (VMT). Data from phase III clinical studies, including the Microplasmin for Intravitreal Injection-Traction Release without Surgical Treatment (MIVI-TRUST) and Ocriplasmin for Treatment for Symptomatic Vitreomacular Adhesion Including Macular Hole (OASIS) studies, have demonstrated the treatment efficacy of ocriplasmin for VMT and full-thickness macular hole (FTMH)...

Central retinal artery occlusion (CRAO) is an infarction to the retina that results in acute, frequently severe vision loss. Long-term complications such as ocular neovascularization (ONV) can occur and result in neovascular glaucoma and vitreous hemorrhage. Recent studies have explored acute hyperbaric oxygen (HBO) therapy as a promising treatment for CRAO to improve long-term vision potential; however, its effects on CRAO complications have not been well characterized. This study was conducted to better characterize the effects of HBO therapy on complications from CRAO...

INTRODUCTION: Neuroticism is a personality trait often described in individuals with glaucoma (GLC), but is not necessarily representative of the total population of patients. There is a population of patients with GLC who are invisible to clinical ophthalmologists; in other words, those who once have been diagnosed with GLC, but spontaneously stop visiting an ophthalmologist. Little is known about their neuroticism personality trait. In the present study, the authors compared the level of neuroticism between patients no longer visiting an ophthalmologist and those who continue visit them regularly...
