Cobalt blue light unit filter - A smartphone attachment for blue light photography.

ABSTRACT:

Purpose

The aim of this study was to carry out blue light photography of fluorescein-stained corneas using a novel smartphone attachment.

Methods

A smartphone attachment known as the cobalt blue light unit (C-BLU) was developed. It can filter out all wavelengths of light except the blue light emerging from the flashlight of a smartphone. A pilot study was carried out wherein the images captured with the C-BLU system were compared with slit-lamp photographs of the same patients. This setup was then used to photo document fluorescein-stained corneas in various clinical settings assembled at point-of-care.

Results

Many pathologies of the fluorescein-stained cornea were captured using the C-BLU filter. It was used effectively in various settings (remote eye camps, intensi
