One's preference for certain time orientations is influenced by many factors including culture. The aim of this research was to describe the phenomenon of time perspective in different cultures. The authors carried out re-evaluation of reliability and validity of the Russian version of the Zimbardo Time Perspective Inventory (ZTPI) scale and compared the findings with the original scale as well as with its adapted versions (French and others). The sample consisted of 1136 people aged 14 to 81 from eighteen Russian cities and was divided into seven age groups. As a result, the five factor structure of the ZTPI was replicated on the Russian sample (reliability and validity proved to be quite high), although certain changes had been made to the test keys because of cultural differences. The five factors of the ZTPI that are similar both in Russian and French samples make it possible to carry out cross-cultural comparisons using this scale. It was also found that women have higher orientation to Past Positive and Present Fatalistic than men. People living in large cities score higher on Present Hedonistic and lower on Future that people living in small towns.

BackgroundMobile phone screens can facilitate stimulation to various components of the visual system and many mobile apps are accepted as a means of providing clinical assessments for the oculo-visual system. Although many of these apps are intended for use in clinical settings, there is a growing number of apps in eye care developed for self-tests and eye exercises for lay people. These and other features, however, have not yet been well described.ObjectiveOur objective was to identify, describe, and categorize mobile apps related to eye care that are available to users in the Canadian iTunes market.MethodsWe conducted an extensive search of the Apple iTunes Store for apps related to eye care. We used the terms “eye,” “eye care,” “vision,” and “eye test” and included apps that are targeted at both lay people and medical professionals. We excluded apps whose primary function is not related to eye care. Eligible apps were categorized by primary purpose, based on how they were described by their developers in the iTunes Store.ResultsOur search yielded 10,657 apps, of which 427 met our inclusion criteria. After removing duplicates, 355 unique apps were subject to further review. We assigned the eligible apps to three distinct categories: 39/355 apps (11.0%) were intended for use by medical professionals, 236 apps (66.5%, 236/355) were intended for use by lay people, and 80 apps (22.5%, 80/355) were intended for marketing eye care and eye-care products. We identified 9 subcategories of apps based on the descriptions of their primary functions. Apps for medical professionals fell into three subcategories: clinical calculators (n=6), clinical diagnostic tools (n=18), and education and networking apps for professionals (n=15). Apps for lay people fell into four subcategories: self-testing (n=153), eye exercises (n=30), patient tools and low vision aids (n=35), and apps for patient education (n=18). Mixed-use apps (n=80) were placed into two subcategories: marketing of individual practitioners or eye-care products (n=72) and marketing of multiple eye-care products or professional services.ConclusionsThe most extensive subcategory pertaining to eye care consisted of apps for use by lay people, especially for conducting self-tests (n=236). This study revealed a previously uncharacterized category of apps intended for use by doctors and patients, of which the primary goal is marketing of eye-care services and products (n=80).

BACKGROUND AND OBJECTIVE: There is an emerging role for optical coherence tomography angiography (OCTA) in detecting microvasculature changes in diabetic retinopathy (DR). This study aimed to investigate visual functions and OCTA parameters of retinal and choriocapillaris (CC) flow in patients with type 1 diabetes mellitus (T1DM) without apparent DR. PATIENTS AND METHODS: Patients and age-matched healthy volunteers were enrolled. All participants underwent low-luminance visual acuity assessment, OCT, and OCTA. Assessed OCTA parameters included foveal avascular zone area, acircularity index, vessel density (VD), skeletonized density, and CC flow deficits. RESULTS: Low-luminance deficit (LLD) was significantly higher in patients with diabetes mellitus and correlated with skeletonized density and VD in the superficial vascular plexus (SVP). In the T1DM group, vessel density and skeletonized density were reduced in the SVP and deep capillary plexus. Flow deficits density and the mean size of the flow deficits were increased in patients with T1DM. CONCLUSION: Functional and microvasculature changes were observed at the preclinical stage of DR. Correlation of LLD and OCTA parameters can be a sign of early neurovascular impairment. [ Ophthalmic Surg Lasers Imaging Retina . 2021;52:S30–S34.]
