What should be done if the fundus picture taken during a Retinal Image is dark and unclear?

When a fundus picture is dark and unclear, dimming the lights in the pre-test room and retaking the pictures is the recommended approach. This action helps to enhance the pupil's dilation and overall visibility of the retina, allowing for a clearer image capture.

Reducing ambient light can lead to pupil dilation, which facilitates more light entering the eye and better visualization of the retinal structures. The retinal camera typically requires optimal lighting conditions to capture detailed images, and by controlling the pre-test room lighting, technicians can significantly improve image quality.

While altering camera settings or other options may seem viable, these actions do not address the immediate issue of pupil size and the influence of external light. Thus, adjusting the light conditions in the pre-test environment specifically supports better imaging results.
