About this study

This study aimed to design and validate a VR-based ophthalmic clinic that replicates traditional tests of visual acuity, stereopsis, and contrast sensitivity within an immersive digital environment. Using a rigorously developed system based onprogrammable interfaces, and standardized testing paradigms, we compared VR assessments against gold-standard clinical tools in a cohort of healthy adult participants. Key outcomes included test consistency, correlation, user acceptability, visual fatigue, and time efficiency. Our findings offer evidence for the viability of VR as a platform for remote ophthalmic testing and pave the way for scalable digital eye care delivery.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Accommodative Response

    The actual amount of accommodation that exists is measured with a skiascope

    Measured: 60 min

  2. AC/A Ratio

    The ratio of accommodation convergence to accommodation is measured and calculated by maddox

    Measured: 60 min

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Accommodative Response (time frame: 60 min). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jun 2025.
