Abstract

PURPOSE

To permit blue light photography with any smartphone using a universal novel solution to aid photo-documentation in ophthalmology.

METHOD

To devise an attachment so as to enable blue light photograph with any smartphone. The BLU patch was developed with similar properties as the traditional cobalt blue filter found in slit-lamps. It was then attached to a smartphone and then various clinical photographs were obtained with it.

RESULTS

BLU patch helped in capturing varied pathologies of the fluorescein stained cornea. Corneal pathologies like corneal ulcers, infiltrates, exposure keratopathy, punctate keratitis, siedel’s test etc to name a few were photographed.

CONCLUSION

BLU patch is a low-cost accessory for any smartphone, without any technical expertise needed to obtain a clear image of the fluorescein stained cornea. Enabling prospects in tele-ophthalmology for photo documentation and monitoring at an affordable level in settings where imaging cannot be done otherwise.
