Global quantitative measures of eye tracking dysfunction (ETD) are crucial for schizophrenia research. Our findings clarify misunderstandings and present differing rates of ETD in schizophrenia compared to Levy et al.

Area of Science:

  • Psychiatry
  • Genetics
  • Neuroscience

Background:

  • Levy et al. reviewed quantitative measures of eye tracking dysfunction (ETD) in schizophrenia.
  • The review discussed the role of ETD in schizophrenia research and genetic homogeneity.

Discussion:

  • This response clarifies misunderstandings regarding the authors' previous work on ETD in schizophrenia.
  • It details the computation of data fit to the Mendelian latent structure model.
  • Discrepancies in reported ETD rates between the authors and Levy et al. are highlighted.

Key Insights:

  • Global quantitative measures of ETD are vital for schizophrenia studies.
  • The authors' mixture analyses and abnormality rates differ from Levy et al.'s findings.
  • A clear explanation of fitting data to the Mendelian latent structure model is provided.

Outlook:

  • Further research is needed to reconcile differing findings on ETD rates in schizophrenia.
  • Refined quantitative measures may improve understanding of ETD's genetic underpinnings.
  • Continued investigation into the genetic homogeneity of ETD in schizophrenia is warranted.
