Application of mydriasis and eye steering in ultrawide field imaging for detecting peripheral retinal lesions in myopic patients

To compare mydriatic and eye-steering ultrawide field imaging (UWFI) with standard non-mydriatic UWFI examination in detecting peripheral retinal lesions in a myopic patient's cross-sectional observational study. 220 eyes from 110 myopia patients with known peripheral retinal lesions in at least one eye were recruited for Goldman 3 mirror contact lens examination. Using Optomap UWFI (Daytona, Optos, UK), non-mydriatic standard and eye-steering UWFI images were taken in the center and eye-steered in the up, down, nose, and temporal gaze directions. Standard and eye steering mydriatic UWFIs were recorded with a central line of sight and four different peripheral lines of sight. We compared the sensitivities of detecting peripheral retinal lesions at various UWFI settings. 141 (64.09%) eyes had peripheral retinal lesions. Sensitivity to detect low to high peripheral lesions is 41.84% (95% CI 33.62% to 50.54%) with standard non-mydriatic UWFI settings and 52.48% (95% CI 44, 08% to 60.75%) with default mydriatic settings. %)was. 75.18% (95% CI 67.21% -82.06%) for non-mydriatic eye-tracking and 86.52% (95% CI 79.76% -91.69%) for mydriatic eye control. Both mydriasis and eye steering techniques increase the sensitivity to detect peripheral lesions with statistical significance (p0.05), and axial length (p> 0.05) also influences peripheral lesion detection independently. It wasn't a factor. Both eye steering technology and mydriasis have the potential to effectively improve sensitivity in detecting peripheral retinal lesions in patients with myopia. Upper and lower quadrant lesions benefited more from eye steering technology. The incidence of myopia is increasing worldwide each year 1, and myopia-related macular disease has emerged as one of the leading causes of blindness 2. Today, more than 3 million myopia patients seek surgical treatment to correct myopia, almost half of whom have severe myopia. 4 Previous studies have shown that self with high myopia, peripheral degeneration such as retinal holes or lacerations, lattice degeneration, and planned intraocular surgery are independent risk factors for retinal detachment. People with a predisposition to retinal detachment were asked in clinical practice.

Longitudinal Changes in Scotopic and Mesopic Macular Function as Assessed with Microperimetry in Patients with Stargardt Disease

Image
  The Nidek MP1S device was used to measure central 20 ° macular sensitivity under mesopic and scotopic conditions. Mean deviations (MD) from normal value for mesopic macular sensitivity for fovea (within 2 ° eccentricity) and extrafovea (4 ° 10 ° eccentricity) and the MD for scotopic sensitivity for extra fovea were calculated. Linear mixed effects models were used to estimate mesopic and scotopic changes and the mMD was 10.7 dB (p <0.001). Longitudinally, all eyes showed a statistically significant deterioration trend: the rates of foveal mMD and extrafoveal mMD and some were 0.72 (95% CI 0.37 to 1.07), 0.86 (95% CI: 0.58 to 1.14) and 1.12 (95% CI.). : 0.66 to 1.57) dB / year. In STGD1, the loss of scotopic macular function preceded the extrafovea and was faster than the loss of mesopic macular function. Scotopic and mesopic macular sensitivities using microperimetry provide alternative visual function results for STGD1 treatment studies. At baseline, all eyes had a larger sMD...

A Revision of the International Classification of Retinopathy of Prematurity

Image
Retinopathy of prematurity (ROP) is still a major threat to premature babies' vision, with some cases resulting in irreversible vision loss. The International Categorization of Retinopathy of Prematurity (ICROP), a clinical classification system for acute ROP, was created in 1984 with input from experts from around the world.  Cryotherapy's efficacy in preventing retinal detachment and vision loss due to ROP was promptly proven in a multicenter clinical trial. 2 Since its inception, ICROP has enhanced clinical care by permitting reliable documenting of ROP, facilitating comparison of serial examinations by numerous doctors, and facilitating consultation with peers. The ICROP has undergone fine-tuning in the past, most recently in 2005. 3 The ICROP3 classification, which was released this year, was updated to better characterise the disease as it is being managed. 4 ICROP3's primary revisions address concepts added over the last two decades that are thought to influence the ...

Independent and integrated ophthalmology – where justice and excellence meet

Image
About 2.2 billion people worldwide are visually impaired, at least half of whom are preventable. Current estimates of preventable causes of moderate to severe visual impairment or blindness include untreated refractive error (88.4 million), cataracts (94 million), glaucoma (7.7 million), corneal opacity (4.2 million), Includes diabetic glaucoma (3.9 million) and trachoma (3.9 million). 2 million), but mostly due to uncorrected presbyopia (826 million). Of gross domestic product.  The World Health Organization's resolution on "Integrated Human-Centered Ophthalmology (IPEC), Including Preventive Blindness and Visual Impairment". At the core of the resolution is to make IPEC the optimal model and ensure its widespread implementation. It is estimated that about two-thirds of the population of India may require free or subsidized eye care, and if they have no such access, they may suffer marginalization and exclusion. Affordable and accessible high-quality care delivered by t...
