ABSTRACT
BACKGROUND: Coronavirus disease 2019 (COVID-19) has created an escalating need for limiting in-person examination and potential viral exposure. Under these circumstances, teleophthalmology allows ophthalmologists to continue providing care to patients while ensuring their safety and that of the medical staff. OBJECTIVE: The primary objective of this study was to assess patient satisfaction with an asynchronous teleconsultation for glaucoma patients in a rural German area. Secondary endpoints were patient adherence and the need to change the therapeutic regime. METHODS: This retrospective, observational, and monocentric study included 50 patients diagnosed with primary open-angle glaucoma (n = 49) and ocular hypertension (n = 1) requiring medication to lower intraocular pressure (IOP). Only patients with well-controlled diseases were included, and a brief questionnaire was evaluated, which was completed one year after the baseline visit. Best-corrected visual acuity (BCVA), IOP measurements, visual fields, optical coherence tomography images of the optic nerve head, ultra-widefield photographs of the fundus, and photographs of the anterior segment of the eye were taken at each visit by an experienced optometrist. RESULTS: Of the 50 patients included, the mean number of follow-up visits in this observation period was 4.4. No patient was lost to follow-up, and there were a total of nine missed follow-up visits (but not lost to follow-up). No patients required a change in their treatment regime during the observational period. Regarding patient-focused assessment, the majority of patients were satisfied or very satisfied with teleconsultation in general. CONCLUSION: Asynchronous teleophthalmology is a promising option and effective means to monitor glaucoma patients. The majority of teleophthalmology patients were satisfied with their teleconsultation and adhered to the follow-up schedule. However, prospective trials with a larger number of patients and a more focused examination on specific patient populations are required. Further trials should also focus on the aspect of cost-effectiveness.
ABSTRACT
The purpose of this study was to evaluate the effect of the E3 Fitness Grips (BioGrip, Inc., Rancho Cordova, CA) on running economy, as measured by oxygen uptake (VO2), and heart rate (HR) during submaximal treadmill running. Eleven subjects, seven female and four male, completed a submaximal running test on a treadmill while VO2 and HR were measured continuously. After achieving steady-state at a speed and grade that elicited a VO2 equivalent to 70% VO2max, the subjects ran for five minutes holding the E3 Fitness Grips (G) and five minutes without the grips (NG). The tests were counterbalanced so half of the subjects held the grips first and half completed the NG condition first. The difference in VO2 and HR between the G and NG conditions were compared to determine the effect on running economy. The mean VO2 (33.2±4.6 vs. 33.2±4.6 ml·kg-1·min-1, p=0.96) and mean HR (172.0±8.9 vs. 172.8±8.9 beats·min-1, p=0.38) were not significantly different between the G and NG conditions during submaximal running. These findings suggest that the E3 Fitness Grips do not significantly alter running economy, as measured by VO2, or HR during submaximal treadmill running.
