Abstract

Purpose: To investigate the advantages offered by a novel Wide Field Spectral Domain-Optical Coherence Tomography (WF SD-OCT) device characterized by Long Term Averaged B-scans in the detection and follow up of chorioretinal affections examined at the ocular oncology service of Luigi Sacco Hospital, University of Milan, Italy.

Methods: Case series study performed using a prototype (OCT2 module) derived from the Heidelberg Spectralis HRA+OCT (Heidelberg Engineering, Heidelberg, Germany). Patients presenting with peripheral lesions difficult to be examined secondary to their anterior position or thickness were included in the study.

Results: 43 eyes affected by miscellaneous chorioretinal affections were included in the study. 5 patients suffered of peripheral exudative hemorragic chorioretinopathy (PEHCR), 13 displayed choroidal nevi, 4 uveal melanomas and 3 had choroidal metastasis. Additionally there were 4 choroidal osteomas, 5 choroidal hemangiomas, 6 vasoproliferative tumors of the retina and 3 sclero-choroidal calcifications. In all cases continuous averaging allowed good visibility of both the deep structures and the vitreous. The thickest lesion which could be imaged measured 3.5 mm. Interestingly, high quality images could be obtained also anteriorly to the equator requiring poor or no pupil dilation.

Conclusions: We evaluated a new prototype of SD-OCT capable to obtain wide field imaging of the retina and choroid characterized by faster images acquisition. WF SD-OCT offered a comprehensive view of both retinal and choroidal affections with the possibility of imaging thicker lesions compared to standard devices. In the future this could represent a useful tool in the daily practice adding useful informations to ocular ultrasonography.
