Area of Science:

  • Neuroscience
  • Ophthalmology
  • Computational Biology

Background:

  • Manual quantification of retinal ganglion cells (RGCs) in animal glaucoma models is time-consuming.
  • Accurate RGC counting is crucial for understanding optic neuropathy progression.

Purpose of the Study:

  • To develop a fully automated and robust method for quantifying β-III-tubulin-stained RGCs.
  • To accelerate RGC image analysis in glaucoma research.

Main Methods:

  • Combined CellProfiler for cell recognition with CellProfiler Analyst for machine-learning-based phenotypic classification.
  • Validated the automated method in a murine model of microbead-induced optic neuropathy.

Main Results:

  • The automated method accelerated RGC image quantification tenfold.
  • 1800 images were analyzed in 3 hours, compared to 72 hours for manual counting.
  • The method demonstrated robustness and user-friendliness.

Conclusions:

  • The developed automated method offers a significant improvement in efficiency for RGC quantification.
  • This technique is easily implementable in any laboratory due to its user-friendly design and use of publicly available software.
  • Facilitates faster and more efficient research in glaucoma and optic neuropathies.
