However — the eye (retina) uses a related enzyme called PDE6 for converting light into nerve signals Filitra 10 Some PDE?5 inhibitors — especially at higher doses — can also (accidentally) inhibit PDE6. PMC nhibition of PDE6 can alter how retina photoreceptors respond to light and color. In practical terms — that may cause: Changes in color perception (for example, a blue or blue?green tint) — sometimes described as “everything looks bluish.” euroclinix.net Potential Risks & When Vision Changes Are More Likely Visual side?effects tend to be dose?dependent: higher doses raise the chance of vision disturbances. PubMed +2 PubMed +2 Besides mild, temporary visual effects, there have been rare but more serious reports associated with ED drugs: for example, a condition called Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION) — which can cause sudden vision loss. quallentpharmaceuticals.com +2 PubMed +2 The risk of such serious problems appears higher in individuals who have pre?existing risk factors for eye/vascular disease (older age, diabetes, hypertension, vascular disease, “crowded disc” anatomy of optic nerve, etc.) — but causation is not always clear.
