A pharmaceutical carrier suitable for topical administration to the eye, comprising:

an oil-in-water microemulsion comprising
(i) an oil selected from the group consisting of isopropyl myristate, isopropyl palmitate, and medium chain triglycerides;
(ii) a pair of surfactants selected from the group consisting of two polysorbates, a polysorbate and propylene glycol, a polysorbate and glycerol, a polysorbate and 1,2,3-triacetoxypropane, polyethoxylated castor oil and 1,2,3-triacetoxypropane, and polyethoxylated castor oil and propylene glycol;
and
(iii) water,
wherein:
the water represents 50 to about 95 percent (w/w) of the pharmaceutical carrier;
the oil and surfactants represent substantially all of the remainder of the pharmaceutical carrier;
