OCT as sensitive indicator of geometric fundus deformities

AbstractPurpose To emphasize the contribution of optical coherence tomography in detecting geometric fundus deformitiesMethods Seven cases of geometric fundus deformities are evaluated retrospectively with regard to OCT (Heidelberg Spectralis), B‐scan ultrasound, fundus imaging, direct ophthalmoscopy and functional examinations, among them acuity, color vision and various perimetric techniques.Results Patients were referred to our hospital because of unexplained reduction in visual acuity or loss within their visual fields, or were identified as being affected from geometric fundus deformity on routine exam. OCT provided the first‐at‐hand finding leading towards the explanation of abnormal visual function, or was the first to point incidentally to a geometric fundus deformity. Ophthalmoscopy (incl. an estimate of paraxial optic path length) and fundus imaging ranked next, whereas B scan ultrasound provided affirmative data. Among functions, visual fields were more often affected than acuity. There were no defects in color vision.Conclusion OCT profiles of the posterior pole of the eye provide a sensitive indicator of geometric fundus deformities, thus leading to an understanding of otherwise unexplained defects of visual function.
