NCT ID: NCT06173245 Completed - Clinical trials for Diabetic Retinopathy

Subfoveal Choroidal Thickness and Visual Acuity After Intravitreal Injection of Ranibizumab in Diabetic Retinopathy

Start date: February 1, 2021
Phase: N/A
Study type: Interventional

The aim of this study is to compare subfoveal choroidal thickness (SFCT) and the visual status before and after intravitreal injection of ranibizumab in diabetic macular edema (DME) with the use of 3D-OCT by enhanced depth spectral-domain imaging (EDI-OCT) with fixating other factors.

NCT ID: NCT06167642 Enrolling by invitation - Multiple Sclerosis Clinical Trials

Retinal Atrophy and Neurofilament Light Chain in People With Multiple Sclerosis Taking Ofatumumab

Start date: May 22, 2023
Phase:
Study type: Observational

This study aims to assess whether, and the degree to which, ofatumumab modulates or reduces rates of retinal atrophy in people with relapsing-remitting MS (RMS), according to baseline serum neurofilament light chain (sNfL) levels.

NCT ID: NCT06131476 Completed - Visual Acuity Clinical Trials

Clinical Investigation of Visual Acuity in Contact Lens Wearers After Instillation of a Lipid- Based Lubricating Eye Drop

Start date: September 16, 2020
Phase: Phase 1
Study type: Interventional

This is a single visit, randomized, double masked, bilateral, non-dispensing, 2×2 crossover study to assess visual acuity.

NCT ID: NCT06054763 Not yet recruiting - Glaucoma Clinical Trials

Buyang Huanwu Decoction and Normal Tension Glaucoma

Start date: October 1, 2023
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to test Buyang Huanwu Decoction in normal intra-ocular pressure glaucoma. The main question to answer is: the effect of Buyang Huanwu Decoction and its safety in patients with normal intra-ocular pressure glaucoma. Participants will take 3 grams of Buyang Huanwu Decoction or placebo for 12 weeks. Researchers will compare treatment group and placebo group to see if the visual acuity, visual field would be improved.

NCT ID: NCT06019806 Recruiting - Visual Acuity Clinical Trials

Effects of Forward Head Posture Correction on Visual Acuity in Low Level Visually Impaired University Students

Start date: September 6, 2023
Phase: N/A
Study type: Interventional

The aim of this research is to find the effect of forward head posture correction on visual acuity and fatigue in low level visually impaired university students. Randomized controlled trials at Cecos University of IT and Emerging Sciences would be done. The sample size would be 48. The subjects would be divided in two groups, 24 subjects Intervention group and 24 in control group. Study duration would be 6 months. Sampling technique applied would be a non-probability convenience sampling technique. Only 18-25 years low level visually impaired university students with forward head posture would be included. Tools used in the study would be asthenopia questionnaire, Snellen chart and CVA angle photogrammetry

NCT ID: NCT05956938 Not yet recruiting - Visual Acuity Clinical Trials

Effect of Action Video Games and Stroboscopic Glasses on Dynamic Visual Acuity.

Start date: January 2024
Phase: N/A
Study type: Interventional

The study aims to observe the possible improvement of performance in dynamic visual acuity (DVA), in terms of speed and trajectory, comparing training using action video games and strobe glasses. The results will allow us to understand which visual training is more beneficial for improving dynamic visual acuity in athletes.

NCT ID: NCT05835193 Completed - Refractive Errors Clinical Trials

Pre-symptomatic Screening of Visual Acuity in Pre-school Students

Start date: April 20, 2023
Phase:
Study type: Observational

The present research process is a prospective, non-interventional clinical study that will be conducted -under the auspices of the Democritus University of Thrace (DUTH)- in the pre-school students of the city of Alexandroupolis, Greece. - The study aims to assess the visual acuity of the kindergarten students. - The measurement of monocular best-spectacle corrected visual acuity will be performed using a web-based visual acuity chart
