Table 1 Case reports of isolated vascular compression of the oculomotor nerve treated by microvascular decompression

Ref.	Case number	Age/sex	Culprit vessel	Vascular anomaly	Clinical Presentation	Past history	Treatment/outcome
Kojo et al[1], 1988	1	47/F	Left PcomA	Tortuous and dilated	1 d, left blepharoptosis and diplopia	Migrainous headache and cerebral aneurysm	MVD, improved at 28 d after surgery
Nakagawa et al[12], 1991	1	59/M	Bilateral PCA and postoperativearachnoidaladhesions	Atherosclerosis	Left-sided, 1 mo, ophthalmoplegia	None	MVD, the left-sided ocular symptoms were improved at 1 mopostoperatively (mild residual diplopia)
					Right-sided, 2 d, ophthalmoplegia		MVD, the right-sided ocular movement and ptosis were improved at 1.5 mo postoperatively (mild residual ptosis)
