Chemical neuromodulation of the retina using native neurotransmitters to biomimetically activate target retinal neurons through chemical synapses is a promising biomimetic alternative to electrical stimulation for restoring vision in blindness caused by photoreceptor degenerative diseases. Recent research has shown that subretinal chemical stimulation could be advantageous for treating photoreceptor degenerative diseases but many of the parameters for achieving efficacious chemical neuromodulation are yet to be explored. In this paper, we investigated how the depth at which neurotransmitter is injected subretinally affects...

AbstractPurpose of ReviewCorneal diseases are a major cause of blindness worldwide, resulting from corneal scarring and neovascularization. There is an unmet need for developing effective therapies to prevent and/or treat corneal neovascularization.Recent FindingsTopical steroid medication, cautery, argon and yellow dye laser, and fine needle diathermy have all been advocated with varying degrees of success. Vascular endothelial growth factor family of proteins play a pivotal role in corneal neovascularization, and current therapies are aimed at disrupting the various steps in this pathway. Advancement in cell-based therap...

Authors: Augstburger E, Héron E, Abanou A, Habas C, Baudouin C, Labbé A Abstract Ischemic optic neuropathies are among the leading causes of severe visual acuity loss in people over 50 years of age. They constitute a set of various entities that are clinically, etiologically and therapeutically different. Anatomically, it is necessary to distinguish anterior and posterior forms. From an etiological point of view, the diagnosis of the arteritic form due to giant cell arteritis requires emergent management to prevent blindness and even death in the absence of prompt corticosteroid treatment. When this d...

This article highlights that though with the availability of proper healthcare facilities, the trend is changing for the causes but still a lot of effort in the form of timely neonatal eye care facilities, pediatric surgical services and proper refraction strategies is required.

Rohit Saxena, Pradeep Sharma, Pediatric Ophthalmology Expert Group# Indian Journal of Ophthalmology 2020 68(2):325-332 Childhood blindness causes significant social and economic burden. Even though pediatric eye care has gained priority under Vision 2020, it continues to come under the purview of tertiary care centers due to lack of knowhow and facilities at primary and secondary level. Currently, India does not have standard guidelines on pediatric eye examination, refraction, and amblyopia management and therefore these are being managed inadequately or inappropriately. In view of this, an expert group of pediatric opht...

This article focuses on delivery of PEC models in India, specifically through the vision center (VC) approach. VCs are part of a larger eye care network and provide PEC in remote rural areas of the country. The authors describe the how PEC is delivered in more than 300 VCs operated by six mentor hospitals in India under the Global Sight Initiative (GSI). Key factors compared include: The role of leadership; human resource planning, including recruitment and retention; service delivery; leveraging technology for planning and reaching key populations; financial sustainability; supply chain management; and quality and monitor...

Conclusion: Whole globe anomaly constitutes a major cause of SVI and blindness, especially in AP. Lens-related pathologies were higher in TS. Nearly 40% of the causes were avoidable. Hence, robust screening methods and strategies must be established for timely intervention to reduce the burden on VI in children.

Conclusion: Teleconsultation has a significant role in the management of anterior segment conditions in bridging the gap between the patients and ophthalmologists in rural India. TO can also play an important role in the diagnosis and management of anterior segment, lid, and adnexa-related pathologies.
