“…Additionally, a build-up of extracellular material between the layers and alterations in the retinal pigment epithelium occur. This build-up causes a localized deficiency of vitamin A, which leads directly to a rise in the adaptation threshold (and a delay in adaptation to low illumination) [112][113][114]. In addition, there is a midperipheral loss of rods at a rate of 0.4% per year.…”

“…In addition, there is a midperipheral loss of rods at a rate of 0.4% per year. On average, an elderly person can take ten minutes to adjust to an environment that a young person would adapt to in two minutes; a significant delay [112][113][114]. A simple aid is to suggest the use of dark lenses encompassing the visual field in a very bright environment, thereby decreasing the adaptation time as light bleaching is avoided.…”

As life expectancy grows, so too will the number of people adversely affected by age. Although it is acknowledged that many conditions and diseases are associated with age, this mini-review will present a current update of the various visual changes that generally occur in healthy individuals disregarding the possible effects of illness. These alterations influence how the world is perceived and in turn can affect efficiency or the ability to perform ordinary daily tasks such as driving or reading. The most common physical developments include a decreased pupil size and retinal luminance as well as changes both in intercellular and intracellular connections within the retina along the pathway to the visual cortex and within the visual cortex. The quantity and the physical location of retinal cells including photoreceptors, ganglion and bipolar retinal cells are modified. The clarity of intraocular organs, such as the intraocular lens, decreases. These all result in common visual manifestations that include reduced visual acuity, dry eyes, motility changes, a contraction of the visual field, presbyopia, reduced contrast sensitivity, slow dark adaptation, recovery from glare, variation in color vision and a decreased visual processing speed. Highlighting these prevalent issues as well as current and possible future innovations will assist providers to formulate treatments and thereby conserve maximum independence and mobility in the modern mature population.

“…[ 13 ] Serious lesions in the retina and choroids of highly myopic eyes have profound implications for color vision, visual acuity, and other visual functions. [ 14 , 15 ] Consequently, the occurrence of high myopia at a young age not only affects pediatric patients physically and psychologically [ 16 ] but also imposes mental and economic burdens on their families. Current research aims to comprehend the structural and blood flow characteristics of the retina in highly myopic individuals, aiding in the prevention of fundus lesions associated with high myopia.…”

“…This study was approved by the Ethics Committee of Enshi Aier Eye Hospital (2023-ae-NO. 14). In this retrospective study, we selected pediatric patients with high pediatric myopia (30 patients, 60 eyes) and pediatric patients with low to moderate myopia (30 patients, 60 eyes) admitted to our hospital from January 2021 to January 2022.…”

To analyze the relationship in retinal thickness, macula retina and choroidal microcirculation in pediatric patients with myopia. Pediatric patients with high myopia (high myopia group, n = 30, 60 eyes) and pediatric patients with low to moderate myopia (low myopia group, n = 30, 60 eyes) admitted to our hospital from January 2021 to January 2022 were randomly selected as the study subjects. Retinal thickness, the blood density of retina, and the blood density of the choroid were collected in each area of the macula by taking optical coherence tomography (OCT) and OCT angiography (OCTA). Pearson correlation analysis was conducted to compare the results from the 2 groups. Outer retinal thickness showed a weak positive correlation with Superficial vascular complex flow density (SVD) and deep vascular complex flow density (DVD) (P < .05), but no significant correlation with choroidal capillary density (P > .05); inner retinal thickness showed a weak positive correlation with SVD and DVD (P < .05), but no significant correlation with choroidal capillary density (P > .05). In pediatric patients with myopia, there is a positive correlation between the blood flow density of macular retina and retinal thickness, and the retinal thickness will become thinner with increasing myopia.

Dark adaptation changes in highly myopic patients

Abstract: In this study, dark adaptation time did not significantly differ between myopic patients and controls but was correlated with axial length in patients with severe myopia and was significantly longer in the presence of retinal pigment epithelium atrophic lesions.
