Early Treatment Diabetic
Retinopathy Study (ETDRS)

BCVA is the primary endpoint for vision in many ophthalmic clinical trials. Standardized measurement and collection of BCVA is key for successful trials. Standardization through certification and centralized data review supports accurate quantification of vision and consistent measures of vision change.

ETDRS BCVA Certification

BCVA certification assures Sponsors that clinical trial site personnel are adequately trained in performing BCVA assessments in a standardized and correct way. In addition, lane certification ensures that all lane and exam room requirements are met.

Centralized Data Review of ETDRS BCVA

Given the importance of BCVA as the primary endpoint for the majority of ophthalmic clinical trials, prompt and accurate review of the BCVA source documents by an ophthalmology specialist is critical. Centralized data review allows sponsors to provide more efficient oversight, with the potential for reduced risk and lower costs.
