The primary site of administration for ophthalmic drugs is indeed in the eye. This is because ophthalmic medications are specifically formulated for delivery directly to ocular tissues, allowing for targeted treatment of various eye conditions, such as glaucoma, infections, or inflammation. The eye has unique anatomical features that facilitate the absorption of these medications, and providing treatment directly to this area maximizes therapeutic efficacy while minimizing systemic exposure and potential side effects.

In contrast, administering drugs in the muscle, dermal layer, or bloodstream involves different pharmacokinetics and targeted sites that are not appropriate for ocular treatments. Muscle administration would generally be used for systemic effects or when intramuscular injection is indicated, while dermal administration targets skin conditions. Bloodstream administration relates to systemic delivery of medications, which would not achieve the local effect desired for treating eye-specific conditions.
