| Usage | Indicated for elevated IOP of ocular hypertension or open-angle glaucoma. |
| Dorzolamide is a sulfonamide but one retrospective study1 suggested that topical CIA's can be safely used despite a patient reported history of "sulfa alergy". Use cautioned as sensitization may occur when sulfonamides are readministered. |
