SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY EVALUATION OF RETINAL STRUCTURE IN PATIENTS WITH SUSACS SYNDROME
To report spectral-domain optical coherence tomography (SD-OCT) features in patients diagnosed with Susacs syndrome.Methods:
Clinical report of two cases.Results:
Spectral-domain optical coherence tomography was performed in two patients diagnosed with Susacs syndrome. Both the patients had normal macular perfusion on fluorescein angiography (FA). However, SD-OCT revealed bilateral, temporal macular atrophy with disorganization and thinning of the retinal layers. The outer plexiform layer showed nodularity and waviness suggestive of ischemic swelling of the bipolar cells.Conclusion:
Retinal structural changes in Susacs syndrome have not been described earlier. Spectral-domain optical coherence tomography may be more sensitive than fluorescein angiography in detecting microstructural retinal alterations in various layers, especially in apparently perfused retina. These findings may provide an insight into the pathogenesis of Susacs syndrome.
