Hierarchical Attention for Sparse Volumetric Anomaly Detection in Subclinical Keratoconus

arXiv — cs.CVThursday, December 4, 2025 at 5:00:00 AM
  • A recent study has introduced a hierarchical attention model for detecting sparse volumetric anomalies in subclinical keratoconus using 3D anterior segment OCT volumes. This model was compared against sixteen modern deep learning architectures, revealing superior performance in sensitivity and specificity over traditional 2D/3D CNNs and ViTs.
  • The advancement in anomaly detection is significant for early diagnosis and treatment of subclinical keratoconus, a condition that can lead to severe vision impairment if not addressed promptly. Enhanced detection methods can improve patient outcomes and reduce healthcare costs.
  • This development highlights a growing trend in medical imaging towards hybrid architectures that combine local feature extraction with global context modeling. As the field evolves, the integration of various deep learning techniques, such as CNNs and ViTs, is becoming crucial for addressing complex challenges in medical diagnostics.
