Purpose
To discuss the clinical features, differential diagnosis and the novel confocal microscopic findings noted in the rare ‘deep blue dot corneal degeneration’.
Methods
Observational case report.
Results
Slit-lamp biomicroscopic examination revealed bilateral, numerous, circular to oval discrete blue opacities at the level of deep stroma and fine grey linear opacities at the level of mid to deep stroma. Confocal microscopy demonstrated two types of corresponding hyper-reflective extracellular lesions: oval deposit-like, most concentrated at a depth of 430–480 µ and needle-like at the depth 330–370 µ.
Conclusions
Deep blue dot corneal degeneration is a rare entity where blue deposits of amyloid are seen in the deep corneal stroma. It should be considered as a differential diagnosis when an old-aged person presents with good vision and the above mentioned findings.
