Loss of cone photoreceptors, crucial for daylight vision, has the greatest impact on sight in retinal degeneration. Transplantation of stem cell-derived L/M-opsin cones, which form 90% of the human cone population, could provide a feasible therapy to restore vision. However, transcriptomic similarities between fetal and stem cell-derived cones remain to be defined, in addition to development of cone cell purification strategies. Here, we report an analysis of the human L/M-opsin cone photoreceptor transcriptome using an AAV2/9...

Sheffali Gulati, Vishal Sondhi
Cerebral palsy (CP) is a neurodevelopmental disorder characterized by abnormalities of muscle tone, movement and motor skills, and is attributed to injury to the developing brain. The clinical features of this entity evolve over time and the specific CP syndrome may be recognizable only after 3-5 y of age; although suggestive signs and symptoms may be present at an earlier age. The management involves neurological rehabilitation (addressing muscle tonal abnormalities, and devising physical and occupational therapies) and diagnosis and management of co-morbidities (including epilepsy, impairment of cognition, vision, hearing, and disturbances of growth and gastrointestinal function)...

PURPOSE: Pterygium is a frequent ocular disease, where the major challenge is the high level of recurrence after its surgical removal. We performed a network meta-analysis to identify, among several adjuvant treatments for primary pterygium, which is the best to prevent recurrence. METHODS: A search was conducted using PubMed, Scientific Electronic Library Online, Latin American and Caribbean Centre on Health Sciences and Cochrane Eyes and Vision Group Trials Register between 1993 and 2015 for randomisedclinical trials (RCTs) comparing adjuvant treatments following primary pterygium surgery...

INTRODUCTION: Because of the great potential of vascular endothelial growth factor inhibitors (anti-VEGF) for retinal exudative diseases, an increased number of patients receives this treatment. However, during this treatment, patients are subjected to frequent invasive intravitreal injections, and the effects on reversing the process of vision loss are uncertain, which may have negative consequences for patients' mental health. One in three patients experience at least mild symptoms of depression/anxiety...

While the development of anti-vascular endothelial growth factor (anti-VEGF) as a therapy for neovascular age-related macular degeneration (AMD) was a great success, the pathologic processes underlying dry AMD that eventually leads to photoreceptor dysfunction, death, and vision loss remain elusive to date, with a lack of effective therapies and increasing prevalence of the disease. There is an overwhelming need to improve the classification system of AMD, to increase our understanding of cell death mechanisms involved in both neovascular and non-neovascular AMD, and to develop better biomarkers and clinical endpoints to eventually be able to identify better therapeutic targets-especially early in the disease process...

RATIONALE: Blunt cerebrovascular injury (BCVI) is a rare complication that may occur after craniocervical trauma. The current literature is limited to extracranial carotid artery injuries; however, no reports have been published on blunt intracranial carotid injury (BICI), especially those associated with optic nerve injury. PATIENT CONCERNS: Here we report on 3 BICI cases that demonstrated optic nerve injuries after craniofacial injuries. All 3 patients showed post-trauma vision loss on the injured side...

There is little published evidence relating to the final visual acuity of children who are identified as having reduced vision at a school screening program. The school vision screening program in Leeds (led by an orthoptist but delivered by health care support workers within the school nursing team) is examined. RESULTS: 7807 children were screened in school between November 1, 2013, and September 1, 2014. Of these, 319 (4%) failed the screen and were referred to the general optometry service and 547 (7%) were referred to the Children's Community Eye Service (CCES)...

REVIEW

Leber's hereditary optic neuropathy (LHON) is a common inherited mitochondrial disorder that is characterized by the degeneration of the optic nerves, leading to vision loss. The major mutations in the mitochondrial genes ND1, ND4, and ND6 of LHON subjects are found to increase the oxidative stress experienced by the optic nerve cell, thereby leading to nerve cell damage. Accurate treatments are not available and drugs that are commercially available like Idebenone, EPI-743, and Bendavia with their antioxidant role help in reducing the oxidative stress experienced by the cell thereby preventing the progression of the disease...

The emergence of yoga therapy in the United Kingdom began about 45 years ago with the emergence of yoga therapy organizations that offered both treatment and training. The integration of yoga into the National Health Service (NHS) is gradually happening Because: (a) yoga research supports its efficacy as a cost-effective, preventive and complementary treatment for a host of non-communicable diseases; and (b) the escalating economic burden of long-term conditions is overwhelming the NHS. The NHS is actively developing 'sustainability and transformation plans' that include yoga...

Clustered regularly interspaced short palindromic repeats (CRISPR) has been gaining widespread attention for its ability for targeted genome surgery. In treating inherited retinal degenerations, gene therapies have had varied results; the ones effective in restoring eye sight are limited by transiency in its effect. Genome surgery, however, is a solution that could potentially provide the eye with permanent healthy cells. As retinal degenerations are irreversible and the retina has little regenerative potential, permanent healthy cells are vital for vision...

Diabetes is one of the leading public health problems worldwide. Diabetic macular edema (DME) is the main cause of vision loss in patients with diabetes. Ideal metabolic control of diabetes is the primary goal of treatment and the basic way of preventing and stopping the progression of DME. Although laser photocoagulation has been the standard treatment of DME for nearly three decades, superior outcomes can be achieved with novel, intravitreal anti-VEGF and steroid therapy. Novel treatment option for DME depends on visual acuity and location/extent of macular thickening based on optical coherence tomography scans...

Carotid cavernous fistulae (CCF) are defined as abnormal connections between the carotid circulation and cavernous sinus. CCFs can be categorized as being direct or indirect. Direct CCFs are usually associated with trauma, whereas indirect CCFs are associated with revascularization following cavernous sinus thrombosis. We present a case of a 53-year-old male who presented with tinnitus, proptosis, conjunctivitis, and blurry vision. The patient had a recent endovascular transvenous embolization that was only partially successful, with a residual carotid cavernous fistula draining to the left superior ophthalmic vein and multiple cortical veins...
