Choroidal Thickness App


Choroidal Thickness App is a medical tool that improves the diagnosis and clinical follow-up of ocular diseases by supporting the evaluation of choroidal membrane.

This CAD system is able to automatically identify the different layers of the eye globe, even in OCT images with lower quality, and calculate the choroidal thickness in the regions of interest defined by ophthalmologists. The visualisation and data integration options available in this medical solution save time to ophthalmologists, provide clinical registries and make the communication with patients easier.

Challenge | Opportunity

The choroid is a vascular layer of the eye globe located between the retina and the sclera and its thickness is affected by a range of diseases such as retinitis pigmentosa and serous chorioretinopathy. Choroidal evaluation is carried out through OCT imaging but current software solutions require excessive inputs from  ophthalmologists and present poor performance in lower quality images.

Automatic segmentation of eye regions eases medical evaluation but the technology available in clinical arena is not able to fulfill the required level of accuracy. Moreover, there is a gap in solutions that allow the combination of two sets of OCT scans, for a better estimation of the choroidal thickness or analysis on the thickness progression.

Main Advantages

  • Construction of a 3D map of the choroidal thickness by integrating multiple sets of OCT B-scans;
  • Ready for large-scale screening;
  • Follow-up of choroidal thickness variations;
  • Option for calculating choroidal thickness in specific areas of the eyes;
  • Perform accurate measurements even in lower-quality images;
  • Parallel or perpendicular integration of OCT scans sets;
  • Allow manual adjustments of the automated measures by the physicians.


This software has been developed to support the diagnosis and clinical follow-up of variations in choroidal thickness, which can be affected either by systemic diseases such as diabetes and  ageing and by ophthalmologic pathologies such as myopia, retinitis pigmentosa and serous chorioretinopathy.
