Abstract

Early detection and treatment are key in limiting vision loss from glaucoma, the second leading cause of blindness worldwide. The alteration of the optic nerve head’s (ONH) morphology, detectable early in the condition, is a key clinical indicator. The current gold standard is subjective observation through a slit lamp. If quantitative diagnostic devices to extract the topography of the ONH could be made objective and affordable, it could mean task shifting glaucoma diagnostics from specialist to primary/community care. A potentially cost-effective solution is to apply digital 3D reconstruction to stereo images obtained through a slit lamp, a mainstay of eye diagnostics, present in practically all ophthalmology and optometry practices. This works shows ONH reconstruction in an eye phantom through a common slit lamp fitted with extremely inexpensive cameras. Quantitative reconstructions, in close agreement with ground truths, were obtained.
