Trifluridine, known by its brand name Viroptic, is primarily utilized in the treatment of viral infections affecting the eye, most notably herpes simplex keratitis. This antiviral medication works by interfering with the DNA synthesis of the virus, thereby inhibiting its ability to replicate and spread. By applying trifluridine directly to the affected area of the eye, it helps to reduce the severity of the infection and promotes healing.

The other options do not align with the primary use of trifluridine. Intraocular pressure is typically managed with different classes of medications, such as ocular hypotensive agents, rather than antiviral drugs. Dry eye syndrome is addressed with lubricating eye drops or anti-inflammatory medications, while color vision deficiency is managed through non-pharmacological means and is not treated using any medications, including trifluridine. Thus, the correct choice focuses on the specific antiviral action of trifluridine in treating viral eye infections.
