Correlation between the orbital and intraocular portions of the optic nerve in glaucomatous and ocular hypertensive eyes
Background/Purpose It has recently been reported that the retrobulbar optic nerve diameter (OND) and cross-sectional area (ONCSA) are reduced in glaucoma. This study was performed to investigate the correlation b...

ERG and EOG abnormalities in carriers of X-linked retinitis pigmentosa
The diagnosis of X-linked retinitis pigmentosa (XL-RP) relies on the identification of the female carriers, in whom fundal abnormalities are often minimal and variable. The electroretinogram (ERG) has been rep...
