PVVAT incorporates ATS-HOTV and E-ETDRS® - Precision Vision
Pioneering Gold-Standard ETDRS Diagnostics
Precision Vision® Expands Clinical Trial Solutions with Validated Computerized Acuity Algorithms
Proudly Announcing E-ETDRS and ATS-HOTV Validation
Precision Vision® prides itself on maintaining its position as the undisputed global leader in uncompromised vision testing media and retro-illuminated logMAR infrastructure. We are thrilled to announce a transformative digital milestone to our foundational testing ecosystem.
Our proprietary PVVAT™ Computerized Acuity System has been officially vetted and validated by the prestigious Jaeb Center for Health Research. This formal certificate confirms that both the standardized ATS-HOTV and advanced E-ETDRS examination algorithms have been flawlessly implemented within our code framework.
Multi-Center Study Eligibility: Backed by this independent compliance verification, the digital PVVAT™ suite is fully approved for immediate deployment in NEI-funded protocols managed by the Jaeb Center, as well as a diverse matrix of private pharmaceutical clinical trial tracks.

Precision Vision’s Historical Role in Defining Ophthalmic Standards
Decades ago, the National Eye Institute’s landmark Early Treatment Diabetic Retinopathy Study (ETDRS) required an entirely new, highly regulated physical testing method to replace erratic traditional charts. Precision Vision was single-handedly relied upon to engineer the first commercially viable, trans-illuminated optotype charts and standardized cabinets for that historical study.
The resulting combination—merging the geometric parameters of the Bailey-Lovie Eye Chart layout with the structural proportions of Dr. Louise Sloan's nonserif optotypes—breathed life into the exact logMAR framework recognized globally today as the absolute "Gold Standard."
While raw raw compounds and technical electrical components have evolved across generations, our manufacturing parameters remain unyielding. We perform exhaustive quality controls throughout every production run to confirm that the strict luminance output ($85\text{ or }160\text{ cd/m}^2$) and absolute uniformity of light distribution across our ETDRS charts remain perfectly constant. This consistency guarantees seamless test-retest reliability whether a patient is sitting in a local practice lane or an international multi-center pharmaceutical trial.
Bailey-Lovie Eye Chart Set Availability
Engineered to perfectly map a patient's exact threshold curves using uncompromised logMAR spacing. Available for immediate clinical integration to eliminate memorization shortcuts and isolate true visual thresholds.
