What this trial studies

This observational study aims to assess the safety of the Terahertz (THz) scanning system in individuals with non-seeing eyes but healthy corneas. Participants will undergo THz scanning, followed by comprehensive eye examinations at various intervals to monitor visual acuity, corneal health, and nerve status. The study hypothesizes that the THz scanning system is safe for application on the human cornea, which is crucial for understanding corneal hydration and preventing conditions like corneal opacification. The findings could provide insights into non-invasive monitoring techniques for corneal diseases.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 21 and older with at least one functionally blind eye that has a healthy cornea.

Not a fit: Patients with a history of major corneal surgery, active inflammation, or systemic diseases affecting the ocular surface may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer and more effective monitoring of corneal diseases, potentially preventing irreversible blindness.

How similar studies have performed: While the use of Terahertz imaging is a novel approach in this context, similar imaging techniques have shown promise in other areas of ocular health.
