Many ophthalmologists are aware of the uses of optical coherence tomography (OCT)1 in diagnosing glaucoma and retinal pathologies such as macular hole and cystoid macular edema. However, anterior segment OCT imaging2 is still rarely used because of lack of dedicated commercial instrumentation. Maldonado et al. have shown that the commercial OCT retinal scanner (Zeiss Humphrey Systems, Dublin, CA) can be used to image corneal anatomy after LASIK.3 This has sparked an interest in developing dedicated anterior segment OCT systems.

San Antonio, TX-A treatment for seasonal allergic conjunctivitis, pemirolast potassium 0.1% ophthalmic solution (Alamast, Santen Inc., Napa, CA), was shown to be more comfortable for patients and equally effective when used twice a day during ragweed season when compared with nedocromil sodium 2% ophthalmic solution (Alocril, Allergan, Irvine, CA). These two drugs are the two latest mast-cell stabilizers that have become commercially available to treat ocular allergies.

London, Ontario, Canada-Patients with seasonal allergic conjunctivitis that includes ocular symptoms may benefit from a combination of fexofenadine HCl capsules (Allegra, Aventis Pharmaceuticals Inc., Bridgewater, NJ) supplemented with the ophthalmic solution of nedocromil sodium 2% (Alocril, Allergan, Irvine, CA).

Olopatadine HCl 0.1% (Patanol, Alcon) is significantly more effective than ketotifen fumarate 0.025% (Zaditor, Novartis), nedocromil sodium 2% (Alocril, Allergan), and azelastine HCl 0.05% (Optivar, Muro) in relieving itching associated with allergic conjunctivitis and has a comfort advantage as well, according to results of prospective, double-masked comparison studies.
