Participation in continuing professional development (CPD) is part of lifelong learning required by ophthalmologists. Metacognition is a new area of educational research. It is important because metacognitive skills are essential in medical education and likely to improve effectiveness of CPD activities. We systematically searched PubMed using the search terms 'metacognition' and 'CPD' or 'continuing medical education (CME)' and found only 5 articles. These articles were supplemented by a broad-based review of published literature including educational psychology, across the continuum of medical education...

Diabetic retinopathy, glaucoma, and age-related macular degeneration are leading causes of vision loss and blindness worldwide. They tend to be asymptomatic in the early phase of disease and therefore require active screening programs to identify the patients requiring referral and treatment. Deep learning-based artificial intelligence technology has recently become a major topic in the field of ophthalmology. This paper aimed to provide a general view of the major findings on the application of deep learning for the classification of eye diseases from common imaging modalities...

Presbyopia affects more than 1 billion people worldwide, and the number is growing rapidly due to the aging global population. Uncorrected presbyopia is the world's leading cause of vision impairment, and as with other causes, the burden falls unfairly on low- and middle-income countries (LMICs), where rates of presbyopic correction are as low as 10%. The importance of presbyopia as a cause of vision impairment is further underscored by the fact that it strikes at the heart of the productive working years, although it can be safely and effectively treated with a pair of inexpensive glasses...

Glaucoma is the leading cause of irreversible blindness in Africa. The condition is treatable but not curable. There are numerous obstacles to glaucoma care in Africa, including availability, accessibility and affordability of treatments, as well as medication nonadherence among patients. Medical therapy is costly relative to the average income in Africa and it requires daily self-dosing by patients. Surgery is of limited availability in many regions in Africa, and a high proportion of patients refuse surgery because it is expensive...

The first description of exfoliation syndrome (XFS) was presented by John Gustaf Lindberg in his doctoral thesis 100 years ago. The syndrome is an age-related disorder in which abnormal fibrillar extracellular material is produced and accumulates in several ocular tissues. Once thought to be peculiar to Scandinavia, XFS is found in almost every race and ethnic group. Subsequent studies provided evidence for the systemic nature of XFS, which involves an aberrant connective tissue metabolism throughout the body...

Neurofibromatosis type 1 (NF1) is an autosomal dominant neurocutaneous disorder affecting 1:3000 births. This familial tumor predisposition syndrome is diagnosed clinically and affects the skin, bones, and nervous system. Malignant tumors can arise in childhood or adulthood and are the commonest cause of mortality in this population. Early diagnosis and management led by a multidisciplinary team remains the standard of care, particularly in the management of optic pathway glioma. Emerging concepts in the genetic patterns of this condition have led to the introduction of new treatment modalities that target the mitogen activated protein kinase (MAPK) and the mammalian target of rapamycin (mTOR) pathways...

During development, the fetal vasculature nourishes the developing lens and retina, subsequently regressing after the formation of the retinal vessels. Persistent fetal vasculature (PFV) occurs as a result of a failure of fetal ocular vasculature to undergo normal programmed involution, which leads to blindness or serious loss of vision. Persistent fetal vasculature is responsible for as much as 5% of childhood blindness in Western countries. The regulatory mechanisms responsible for fetal vascular regress remain obscure, as do the underlying causes of the failure of regression...

Glaucoma is a serious and irreversibly blinding eye condition of public health importance in Africa. The absence of distinct early symptoms makes the condition hard to recognize by patients. The gradual vision deterioration that occurs is worse in one eye, thereby making it difficult for those affected to be aware of the vision loss until the advanced stages of the disease. We discuss the epidemiology of glaucoma in sub-Saharan Africa, highlighting the risk factors for the disease as well as risk factors for blindness in glaucoma patients...

The burden associated with the rising prevalence of myopia and high myopia, and the associated vision impairment and sight-threatening complications, has triggered the need to evaluate strategies to control the progression of myopia. We provide an overview of the literature on the use of optical (spectacles, contact lenses, and orthokeratology) and pharmaceutical approaches to slow progress of myopia. The evidence indicates that myopia progression can be slowed by varying degrees using these strategies. All approaches play a role in the management of myopia as needs and requirements of an individual vary based on age, suitability, affordability, safety of the approach, subjective needs of the individual, and rate of progression...

Visual impairment resulting from pathological myopia is a serious issue worldwide. This is mainly due to the development of different types of myopic maculopathy. Despite being a major cause of visual impairment worldwide, myopic maculopathy was not consistently defined until 2015. To overcome this problem, the Meta-Analysis for Pathologic Myopia study group proposed a simplified, uniform classification system for myopic maculopathy. Among several lesions of myopic maculopathy, myopic choroidal neovascularization (CNV) is 1 of the most common and severe vision-threatening complications...

Vision impairment and blindness arise both as a cause, and a consequence, of poverty. Achievement of the United Nations Sustainable Development Goals in providing universal access and equity in eye care, both within and between among countries, remains challenging. A severe shortage of eye care providers is creating unnecessary blindness and vision impairment in developing communities worldwide. Education and training develops and strengthens the capacity of emerging nations to contribute to global eye health and the World Health Organization Development Goals in an effective and sustainable way...
