Abstract: The bone morphogenetic protein (BMP) family of proteins has a multitude of roles throughout the body. It plays important roles in development and in the adult vascular endothelium, by modulating the angiogenic response. The endothelial-specific receptor BMP receptor Alk1 is of particular importance in the proper remodeling of the vasculature and its ligand BMP9 has been shown to be a potent inhibitor of neovascularization. Dysregulated BMP signaling has been linked to multiple vascular diseases and can lead to the abnormal angiogenesis. We therefore investigated the role of BMP9/Alk1 signaling in retinal angiogenesis, and its therapeutic implications for vascular pathologies of the eye.

Abstract: Pediatric neuro-ophthalmology is a subspecialty within neuro-ophthalmology. Pediatric neuro-ophthalmic diseases must be considered separate from their adult counterparts, due to the distinctive nature of the examination, clinical presentations, and management choices. This manuscript will highlight four common pediatric neuro-ophthalmic disorders by describing common clinical presentations, recommended management, and highlighting recent developments. Diseases discussed include pediatric idiopathic intracranial hypertension (IIH), pseudopapilledema, optic neuritis (ON) and optic pathway gliomas (OPG). The demographics, diagnosis and management of common pediatric neuro-ophthalmic disease require a working knowledge of the current research presented herein. Special attention should be placed on the differences between pediatric and adult entities such that children can be appropriately diagnosed and treated.

Abstract: Pathologic myopia is the major cause of the loss of the best-corrected visual acuity (BCVA) worldwide, especially in East Asian countries. The loss of BCVA is caused by the development of myopic macula patchy, myopic traction macula patchy, and myopic optic neuropathy (or glaucoma). The development of such vision-threatening complications is caused by eye deformity, characterized by a formation of posterior staphyloma. The recent advance in ocular imaging has greatly facilitated the clarification of pathologies and pathogenesis of pathological myopia and myopia-related complications. These technologies include ultra-wide field fundus imaging, swept-source optical coherence tomography, and 3D MRI. In addition, the new treatments such as anti-VEGF therapies for myopic choroid all neovascularization have improved the outcome of the patients. Swept-source OCT showed that some of the lesions of myopic maculopathy were not simply chorioretinal atrophy but were Bruch’s membrane holes. Features of myopic traction maculopathy have been analyzed extensively by using OCT. The understanding the pathophysiology of complications of pathologic myopia is considered useful for better management of this blinding eye disease.

Abstract: Corneal blindness represents one of the world’s three major causes of blindness, and the fundamental problem of corneal transplantation is a severe shortage of donor tissues worldwide, resulting in approximately 1.5 million new cases of blindness annually. To address the growing need for corneal transplants two main approaches are being pursued: allogenic and bioengineering cornea. Bioengineering corneas are constructed by naturally generating an extracellular matrix (ECM) component as the scaffold structure with or without corneal cells. It is well established that the scaffold structure directs the fate of cells, therefore, the fabrication of the correct scaffold structure components could produce an ideal corneal substitute, able to mimic the native corneal function. Another key factor in the construction of tissue engineering cornea is seed cells. However, unlike the epithelium and stroma cells, human cornea endothelium cells (HCECs) are notorious for having a limited proliferative capacity in vivo because of the mitotic block at the G1 phase of the cell cycle due to “contact-inhibition”. This review will focus on the main concepts of recent progress towards the scaffold and seed cells, especially endothelial cells for bioengineering cornea, along with future perspectives.

Abstract: In a rapidly changing world, there is an increased need to cultivate ophthalmologists who are not only technically capable but also possess the leadership skills required to be at the forefront of change. Ophthalmologists make daily frontline decisions that determine the quality and efficiency of care based on their leadership qualities. However, they also educate, advocate, perform research, run departments and work in practices—all of which require the practice of effective leadership. Although the need for ophthalmic leadership has been recognised, few training programs offer leadership skills as a component of their core curricula, focussing on clinical knowledge with less emphasis on teaching of non-clinical professional competencies. Clinicians who participate in leadership development are more likely to feel empowered to provide patient-centred care, develop a greater self-awareness and confidence to initiate positive change and promote better team alignment. In turn, the ophthalmic profession collectively benefits from effective leadership as organizations are better run, issues are advocated more globally and challenges are address holistically by ophthalmologists who are not merely technically capable surgeons or researchers, but effective communicators and collaborators. In this paper, we explore the role of leadership in the spheres of healthcare and ophthalmology. We discuss the value of leadership across clinical, educational and organisational levels, with specific emphasis on the current state of development and conclude with a series of recommendations to ensure the continued development of effective ophthalmic leaders into the future.

Abstract: Presentations using PowerPoint or similar software are probably the most commonly used format that doctors use for teaching in medical school, during residency, at medical meetings and other continuous medical education (CME) activities. However, their effectiveness has been questioned by many. This article intends to provide, in a synthetized way, several recommendations that can help make presentation more effective.

Abstract: Timely and widely available, social media (SM) platforms and tools offer new and exciting learning opportunities in medical education. Despite scarce, we sought for a body of consistent evidence allowing us to substantially approach the concept of SM and how physicians as learners and medical educators can use SM based-education to benefit their clinical practice and their patients’ outcomes. We correlate education theories with the progression of world-wide web phases and how this influences the process of teaching and learning. We mention some examples of SM tools already in use in healthcare education. Potential advantages and effectiveness SM in medical education, as well as limitations of SM and pre-requisites for its use are discussed. Our concluding remarks underline the good practices in effectively utilizing SM in healthcare education.
