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: Complications of myopia have become an important public health issue with serious socio-economic burdens. Prevention and treatment are both important. The Taiwan Student Vision Care Program (TSVCP) promoted by Ministry of Education (MOE) has been carried out for 3 decades in Taiwan. The myopia prevalence has increased rapidly to a high level and therefore myopia prevention has continued to be the most important item in the program. Therefore, TSVCP aims to decrease the prevalence of myopia, in order to decrease the high myopia related blindness in the future. Recently, outdoor activity has been found to be an important protective factor for myopia and was implemented in TSVCP since 2010. Afterwards, the nationwide vision impairment rate (uncorrected vision 20/25 or less) of elementary school students declined unprecedentedly and continuously in recent years. Evidence-based protective and risk factors for myopia are now clearer. Widespread acknowledgement of myopic disease, preventing the onset of myopia, prompt diagnosis, and early treatment to control progression are all important.
Abstract: Successful management of a case of aggressive posterior retinopathy of prematurity (APROP) poorly responsive to laser therapy with intravitreal bevacizumab (IVB) is discussed. IVB is useful as rescue therapy in such cases, if given within the correct window period post laser therapy.
Background: Disruption of the microstructure in corneal stroma can lead to the loss of transparency. The lack of a characterization method for the microstructure prevents such scaffolds to be implemented in tissue transplantation. The non-invasive, three-dimensional (3D) rendering multiphoton microscopy (MPM) poses the potential to solve this problem.
Methods: MPM images and data analyses were performed with three kinds of samples with known and different quality. Isosurfaces (ISOs) were constructed for the evaluation of void volume and collagen distribution.
Results: The differences in the microstructures of these samples were revealed with clear indications and links to their behaviours in rehydration and possible transparency. According to this analysis, the scaffold with the highest void space ratio amongst the three presented the highest successful rates to be thoroughly rehydrated.
Conclusions: Such a method can be developed for assessing the quality of tissue engineered corneas, or donated corneas, and be useful as a powerful research tool in cornea related research.
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.
