Optic coherence tomography in a patient with diffuse unilateral subacute neuroretinitis.
OBJECTIVE
To measure retinal nervous fiber layer (RNFL) thickness using OCT3 (Carl-Zeiss) in patients with diffuse unilateral subacute neuroretinitis (DUSN) with or without live worm and correlate it with visual acuity.


METHODS
RNFL thickness, using RNFL thickness 3.4 program and best corrected visual acuity were measured in patients with DUSN between January 2005 and December 2006.


RESULTS
Thirty-eight patients, aged 9 - 42 years were selected, of whom 20 had live worm. Mean RNFL was 71.55 +/- 27.26 in the DUSN eye and 103.07 +/- 20.66 in the contralateral eye (p<0.001). Pearson's correlation between visual acuity and RNFL was r= -0.522 (p<0.001) in the DUSN eye and r= -0.097 (p=0.509) in the contralateral eye.


CONCLUSIONS
RNFL thickness in DUSN patients is directly proportional to visual acuity. Further research is needed to reinforce the correlation between visual acuity and thickness of the nerve fibers in patients with DUSN to follow them after the treatment.
