--- abstract: 'Unintended intravascular injection from inferior alveolar nerve blocks can result in frustrating distant complications affecting such structures as the middle ear and eyes. Possible complications affecting the eyes include blurring of vision, diplopia, mydriasis, palpebral ptosis and amaurosis ( temporary or permanent). In this article, we present a complication that has been reported only rarely. Two patients developed transient loss of power of accommodation of the eye resulting in blurred vision after routine inferior alveolar nerve blocks on the ipsilateral side. Clear vision returned within 10 - 15 minutes after completion of the blocks. The possible explanation for this phenomenon is accidental injection into the neurovascular bundle of local anesthetic agents, which were carried via the blood to the orbital region. This resulted in paralysis of a branch of cranial nerve III, the short ciliary nerves that innervate the ciliary muscle, which controls accommodation.' altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: - ngeowy@um.edu.my - ~ - ~ creators_name: - family: Ngeow given: W.C. honourific: Dr. lineage: '' - family: Shim given: C.

He graduated from the University of Malaya in 1992 and was a private practitioner for 9 months before he was offered the post of tutorship at his alma matter. Three years later, he went to do a house job at the Queen Victoria Hospital in East Grinstead, England. He obtained his Fellowship in Dental Surgery from the Royal College of Surgeons in Ireland and the Royal College of Surgeons ofEngland in 1996. He subsequently returned to Malaysia and was a pioneer lecturer at the then newly established Universiti Kebangsaan Malaysia. He left for private practice in 1999 but the temptation to return to academic life was greater, hence he returned to the University of Malaya the subsequent year. His research interest are craniofacial anthropometry, variations of the mandibular nerve, and recovery of peripheral nerves after microsurgical repair. \r\n \r\n\r\nAREAS OF EXPERTISE\r\n\t\r\nDentofacial Anthropometry (Head & Neck, anthropology)\r\n\r\nDental Analgesics (analgesic, local anaesthetic, COX-2 inhibitors)\r\n\r\nSurgical Anatomy (mental foramen, anterior loop)" sword_depositor: ~ sword_slug: ~ thesistype: ~ title: 'Transient loss of power of accommodation in 1 eye following inferior alveolar nerve block: report of 2 cases' type: journalp userid: 16514 volume: 72
