To report the diagnosis and management of a patient with chronic ophthalmic topical anesthetic abuse and floppy eyelid syndrome. We describe the case of a 47-year-old man suffering from persistent bilateral ocular irritation and chronic corneal erosions. The patient was
To study the association between the insertion location of iris root and narrow angle. This was a prospective observational study. A total of 142 eyes of 142 subjects were recruited, including 78 with narrow angles and 64 normals. All participants
Proxymetacaine and oxybuprocaine were clinically used for topical ocular anesthesia but never for spinal anesthesia, and therefore spinal anesthetic effects of proxymetacaine and oxybuprocaine were performed and compared with bupivacaine and lidocaine. After rats were injected intrathecally with proxymetacaine, oxybuprocaine
