Randomized Controlled Trial Comparative Study Clinical TrialComparison of ketorolac tromethamine, diclofenac sodium, and moist drops for ocular pain after radial keratotomy.
To compare the 2 most popular commercially available topical nonsteroidal anti-inflammatory drugs (NSAIDs) in the treatment of ocular pain following radial keratotomy (RK). ⋯ Both ketorolac tromethamine and diclofenac sodium were more effective in reducing post-RK discomfort than the control (moist artificial tears). Given the large number of tests and the small number that tested as significant, the significant differences (7 of 210 measurements) observed among the 3 treatment groups probably occurred by chance, although the improved foreign-body sensation, functionality, and compliance scores in the ketorolac group during the first 4 hours might be clinically important.

After having a retrobulbar injection for anesthesia before cataract surgery, a patient developed dysarthria. This was the presenting sign for penetration of the optic nerve sheath by the retrobulbar injection, with subsequent brainstem anesthesia. Thereafter, the patient demonstrated cranial nerve dysfunctions with tongue deviation, tachycardia, hypertension, and contralateral sixth and third nerve palsies. I believe this is the first documented case in which dysarthria is the presenting sign for brainstem anesthesia resulting from a retrobulbar injection.
