Sustenance of visual function is the ultimate focus of ophthalmologists. Failure of complete recovery of visual function and complications that follow conventional treatments have shifted search to a new form of therapy using stem cells. Stem cell progenitors play a major role in replenishing degenerated cells despite being present in low quantity and quiescence in our body. Unlike other tissues and cells, regeneration of new optic cells responsible for visual function is rarely observed. Understanding the transcription factors and genes responsible for optic cells development will assist scientists in formulating a strategy to activate and direct stem cells renewal and differentiation. We review the processes of human eye development and address the strategies that have been exploited in an effort to regain visual function in the preclinical and clinical state. The update of clinical findings of patients receiving stem cell treatment is also presented.

The treatment of corneal blindness due to corneal diseases and injuries often requires the transplantation of healthy cadaveric corneal endothelial graft tissue to restore corneal clarity and visual function. However, the limited availability of donor corneas poses a significant challenge in meeting the demand for corneal transplantation. As a result, there is a growing interest in developing strategies alleviate this unmet need, and one of the postulated approaches is to isolate and expand primary human corneal endothelial cells (HCECs) for use in cell therapy.

Behçet's disease is a kind of variable vessel vasculitis (VVV) and inflammatory systematic disease affecting various organs of the body. The cause of the disease is idiopathic but is most commonly genetic in origin. A positive skin prick test (dermatographia), genital sores, eye irritation, skin sores, and at least three episodes of mouth sores in a year confirm the diagnosis.

Remote sighted assistance (RSA) offers prosthetic support to people with visual impairments (PVI) through image- or video-based conversations with remote sighted assistants. While useful, RSA services introduce privacy concerns, as PVI may reveal private visual content inadvertently. Solutions have emerged to address these concerns on image-based asynchronous RSA, but exploration into solutions for video-based synchronous RSA remains limited.

Introduction: Cataracts are associated with a decline in both cognitive and visual functions. This study examines postoperative changes in cognitive and visual functions in patients with age-related cataracts, focusing on the differential effects of unilateral and bilateral cataract surgeries on these functions. Additionally, the study evaluates changes in cognitive function following cataract surgery in individuals with mild cognitive impairment (MCI).

Background The objective of this review is to study the demographics, aetiology, clinical findings, and surgical outcomes of patients who presented with ocular trauma and underwent emergency operations at Hospital Kuala Lumpur, Malaysia. Methods Patients who presented from 2016 to 2023 with ocular trauma and underwent emergency ocular surgery were identified and their medical records were reviewed with respect to demographics, mechanism of injury, type of injury, initial presenting visual acuity and final visual acuity after surgery. Components of the ocular trauma score (OTS) were also recorded.
