Today's world acknowledges the escalating significance of assistive technology (AT) in mitigating functional limitations for individuals with disabilities, those suffering from chronic debilitating illnesses, and the elderly. selleck inhibitor The conclusion is clear: all people, temporarily or permanently, will ultimately require assistive technology to boost their physical and functional capacities, thereby improving independent living, social participation, and educational attainment. Concurrently, the demand for AT is anticipated to increase, concentrated primarily within nations characterized by low-to-middle-income status. Similarly, in India, the prevalence of unmet or met needs for assistive technology (AT) remains unknown, yet the demand is poised to escalate. A substantial gap exists between the requirements for assistive technology and the accessibility of such technology. Various initiatives, led by the WHO, are in place to promote the use of assistive technologies for its member states, stemming from the 2018 resolution of the 71st World Health Assembly. The UN Sustainable Development Goals (SDGs) pledge that no individual's personal attributes should determine their exclusion. India, a ratified member of the WHO and UN, must harmonize its policies with the initiatives of these global organizations. India, despite encountering myriad difficulties, needs to formulate an evidence-based AT policy, effectively integrated into the existing healthcare system, in partnership with both government and non-government organizations, including industrial enterprises. This article delves into the necessity, accessibility, and potential obstacles surrounding AT services within India. Anti-inflammatory medicines We concluded with a review of diverse AT initiatives in the country and potential recommendations to enhance AT service provisions throughout the nation.
Visual deprivation during the crucial early years of life can manifest as amblyopia, a condition impacting either monocular or binocular visual acuity. The most common cause of impaired vision in children is refractive error, followed by the condition we are currently focusing on in second place. helicopter emergency medical service Patching forms the cornerstone of amblyopia treatment, with atropine penalization and filters being less typical adjunctive therapies. These therapies are specifically designed to improve the visual acuity in the amblyopic eye, and only that eye. Prolonged periods are necessary for gains to be realized, despite their compliance and psychosocial challenges. Experimental studies reveal binocular cortical communication in amblyopes and the lasting effects of neural plasticity, observed in both late childhood and adulthood. Using this as a foundation, the binocular vision therapy that focuses on stimulating both eyes, not just the amblyopic eye, was established. The therapies' visual tasks are purposely designed to be executable exclusively via binocular vision. From rudimentary red-green glass games to immersive 3-D experiences and cinematic viewing, the tasks exhibit diverse complexity. Preliminary findings indicate that binocular vision therapy has produced sustained enhancements in visual sharpness and might serve as a valuable supplement, or even a replacement, for conventional amblyopia treatment. Our intent in this article is to characterize the various binocular vision therapies, and subsequently review the related literature.
Within the working-age population, diabetic macular edema (DME) represents a significant cause of visual impairment. Deep learning models are now capable of detecting diabetic macular edema (DME) from a variety of sources, including two-dimensional retinal images and optical coherence tomography (OCT) images. The algorithms' performances show fluctuation, often prompting concerns about their usefulness in clinical scenarios. In healthcare settings constrained by resources, these algorithms can substantially contribute to the determination of appropriate referrals and treatments. The survey elucidates a spectrum of macular edema detection methods, including cutting-edge research, aimed at informing research groups, healthcare professionals, and diabetic patients about the significance of deep learning in retinal image detection and classification procedures. The period from the beginning of their availability until March 31, 2022, was covered in the search of electronic databases, like PubMed, IEEE Explore, BioMed, and Google Scholar, and the bibliographies of published papers were also reviewed. The study's methodology conformed to the PRISMA reporting guidelines for systematic reviews and meta-analyses, adhering to the preferred reporting items. Deep learning models, encompassing their precision, training epochs, anomaly detection capabilities for limited datasets, theoretical concepts, and application-level hurdles, were scrutinized. A comprehensive analysis of 53 studies evaluated deep learning model performance on 1,414,169 CT volumes, a significant number of B-scans, 1,414,169 patients, and 472,328 fundus images. The comprehensive area under the receiver operating characteristic curve (AUROC) was 0.9727. The study observed a 96% sensitivity (95% CI: 94-98%) for DME detection when using OCT imagery. Using fundus images to identify DME yielded a sensitivity of 94%, with a 95% confidence interval of 090-096.
Pediatric handheld fundus cameras, epitomized by the RetCam, 3netra Forus, and Phoenix ICON pediatric retinal camera, have substantially aided in the detection and screening of retinopathy of prematurity (ROP), especially in nations with limited ophthalmological expertise. Thanks to the recent introduction of smartphone-based camera technology, pediatric fundus photography is now more accessible and portable than ever. The incorporation of ultra-wide field fundus cameras, trans-pars-planar illumination pediatric fundus cameras, and the utilization of artificial intelligence, deep learning algorithms, and handheld SS-OCTA can revolutionize imaging accuracy and record keeping. This paper investigates the features, strengths, weaknesses, and effectiveness of current and forthcoming imaging technologies for retinopathy of prematurity (ROP), ultimately advocating for the incorporation of telescreening as a standard screening practice in both developed and developing regions.
Irreversible blindness is a tragic outcome of glaucoma, a widespread issue internationally. The only currently known approach to stop further harm to the optic nerve head is by managing intraocular pressure (IOP). Pharmacotherapy is the principal therapeutic intervention in glaucoma management. Prostaglandin analogs (PGAs) have emerged as the initial treatment choice for glaucoma in recent years, marking a noteworthy advancement. The significant rise in usage of PGAs, as opposed to traditional -blockers, stems from their exceptional effectiveness, their simple daily dosing regimen, the superior regulation of intraocular pressure throughout the day, and their favorably lower risk of systemic side effects. Through this review article, we intend to provide information on the different PGAs being used and the cutting-edge, promising medications emerging.
In the global arena, glaucoma, the second leading cause of visual impairment, is estimated to impact 575 million people. To halt the progression of visual field deficits in glaucoma, the primary therapeutic approach centers on reducing intraocular pressure, the sole proven treatment method for this condition. Glaucoma patients are believed to benefit from yoga practices, which are thought to lower intra-ocular pressure and prevent further eye damage. Accordingly, a systematic review was undertaken to examine the scientific evidence regarding yoga and intraocular pressure within the context of glaucoma. The investigation of the literature was underpinned by the critical role of PubMed, the Cochrane Library, and Google Scholar. To evaluate the quality of the clinical trials, the Jadad Scale was utilized; similarly, the JBI Critical Appraisal Checklist was used to evaluate the quality of the case studies included. A final review of studies on yoga and intra-ocular pressure in glaucoma patients, conducted between 2007 and 2021, included six studies after rigorous quality assessment and eligibility evaluation. Patients with glaucoma who underwent Jyoti-trataka (steady gazing) and particular slow yogic breathing techniques showed a decrease in intra-ocular pressure, according to the outcomes. Research on inversion Asanas (yoga postures), conversely, revealed a rapid rise in intra-ocular pressure soon after their initiation. The meta-analysis's inclusion of three high-quality RCTs demonstrated a greater improvement in intra-ocular pressure for yoga groups in both eyes compared to the control groups. However, limitations existed, such as a small sample size, inconsistencies in study quality, a prolonged follow-up period, and different yoga practices implemented. For a better grasp of the subject matter and surpassing the inherent limitations, studies involving more subjects and longer follow-up periods are warranted.
The gradual and relentless loss of retinal ganglion cells, a hallmark of glaucoma, a series of interconnected optic nerve diseases, causes a progressive and irreversible loss of vision, leading to complete blindness. Prolonged neglect of optic nerve damage invariably results in visual impairment and, eventually, full loss of sight. The most common form of glaucoma, encompassing a significant portion of glaucoma cases, is primary open-angle glaucoma (POAG). A range of environmental and genetic elements play a significant role in the genesis of this complex and heterogeneous condition. Anticipating the year 2040, a projected 1,118 million people worldwide will be diagnosed with glaucoma, with a substantial proportion of this figure attributable to patients in Asia and Africa. This review intends to elaborate on how nuclear and mitochondrial genes, along with their various mutations, influence the pathophysiology of POAG. PubMed and Google Scholar databases were electronically combed for publications up to the end of September 2022.
