Optical coherence tomography (OCT) findings in congenital/long-standing homonymous hemianopia.
OBJECTIVE
To report abnormalities of retinal nerve fiber layer (RNFL) thickness using optical coherence tomography (OCT) in patients with trans-synaptic degeneration.


METHODS
Observational case reports.


METHODS
Two patients with congenital/long standing occipital lobe lesions who had asymptomatic homonymous hemianopic field defects were examined using OCT.


RESULTS
In case 1, there was loss of RNFL in the projection of the nasal hemifovea temporally and the horizontal projection nasally in the right eye and thinning in the superior and inferior temporal arcades in the left eye corresponding to visual field abnormalities. In case 2, abnormalities in the RNFL pattern corresponded to the visual defects even though the field defect was incomplete.


CONCLUSIONS
OCT measurements of the RNFL provide useful information in the diagnosis of congenital/long standing occipital lobe lesions.
