    9. OPTICAL COHERENCE TOMOGRAPHY FEATURES OF ACTIVE AND INACTIVE RETINAL NEOVASCULARIZATION IN PROLIFERATIVE DIABETIC RETINOPATHY

      OPTICAL COHERENCE TOMOGRAPHY FEATURES OF ACTIVE AND INACTIVE RETINAL NEOVASCULARIZATION IN PROLIFERATIVE DIABETIC RETINOPATHY
      Purpose: To describe spectral domain-optical coherence tomography features of retinal neovascularization in proliferative diabetic retinopathy and thus to identify novel signs of new vessel activity. Methods: Retrospective, cross-sectional study. Data were collected over a 9-month period. Spectral domain optical coherence tomography scans were performed over areas of new vessel complexes (NVC) in both the disk and elsewhere, and were qualitatively graded by two masked observers. New vessel complexes activity was ...
