Rapidly lowering intraocular pressure in the affected eye often needs a timed combination approach that uses two drugs with different mechanisms. Latanoprost lowers IOP by increasing uveoscleral outflow, while dorzolamide decreases aqueous humor production. Administering alternating drops every few minutes for about 30 minutes delivers a rapid, additive effect from both mechanisms, and then rechecking the IOP confirms how well the pressure has fallen and whether further treatment is needed. This approach is more effective for urgent or acute assessment than a single nightly drop or a single daily dose, which would not produce the same prompt reduction.
