Riboflavin (vitamin B2) is part of the vitamin B group. Riboflavin 5’-phosphate is the precursor of two coenzymes, flavin adenine dinucleotide and flavin mononucleotide, which catalyze oxidation/reduction reactions involved in a number of metabolic pathways. FAD and riboflavin phosphate in foods are hydrolyzed in the intestinal lumen by nucleotide diphosphatase and a variety of nonspecific phosphatases to yield free riboflavin, which is absorbed in the upper small intestines by a sodium-dependent saturable mechanism. Riboflavin has been used in several clinical and therapeutic situations. For over 30 years, riboflavin supplements have been used as part of the phototherapy treatment of neonatal jaundice. Corneal ectasia is a progressive thinning of the cornea; the most common form of this condition is keratoconus. Collagen cross-linking is a non-surgical treatment intended to slow progression of corneal ectasia by strengthening corneal tissue. The standard protocol calls for application directly to the eye of a 0.1% riboflavin solution for 30 minutes followed by 30 minutes of ultraviolet-A irradiation with a wavelength of 370 nm and power of 3 mW/cm2. Under the conditions used for corneal collagen cross-linking, riboflavin 5‘-phosphate functions as a photo enhancer and generates singlet oxygen which is responsible for the cross-linking.

Sample Use Guides

In Vivo Use Guide

instill 1 drop topically on the eye every 2 minutes for 30 minutes. After 30 minutes, examine the eye under slit lamp for presence of a yellow flare in the anterior chamber. If flare is not detected, instill 1 drop every 2 minutes for an additional 2 to 3 drops and recheck for yellow flare. Once flare is observed, perform ultrasound pachymetry. If corneal thickness is less than 400 microns, instill 2 drops every 5 to 10 seconds until the corneal thickness increases to at least 400 microns.
