“…Photophobia and, ultimately, blepharospasm affect the quality of life to such an extent that the slightest glimmer of sunlight can be debilitating. In addition, crystal accumulation over a period of years can cause the formation of corneal scars, keratitis and cataracts, as well as band keratopathies (Gahl et al, 2000). The oral form of Cystagon has no effect on depleting corneal crystals due to poor drug availability stemming from the absence of vasculature in the cornea (Gahl, et al 1987;Gahl and Kuehl, 2000), thus cysteamine must also be administered topically in the form of eye drops.…”

“…Compliance with the use of eye drops is a major issue however, as in order to achieve the maximum benefit in their current formulation these drops must be routinely administered every hour while awake (Gahl and Kuehl, 2000;Gahl, et al 2007). This is due to a low bioavailability commonly reported for topical eye treatments, with tissue contact time varying from 1-2 minutes (Gangrade, et al 1996;Jansook, et al 2010;Le Bourlais, et al 1998) to 5 minutes (McKenzie and Kay 2015;Robinson, 1989;Shell, 1984;Urtti and Salminen 1993).…”
