Summary

Anatomical ophthalmological connections and their dynamics are still debated in the scientific community. However, their considering is essential in many surgeries (strabismus, cataract, refractive...) or in clinical practice.

The correlation between these biometric values would make it possible to refine the knowledge related to these landmarks and thus offer better ophthalmological management by integrating these variables into the clinical examination.

The aim of the study is to analyze the correlation between the angle lambda and the ocular dominance depth in healthy individuals without ophthalmologic disorder.

Then, seconds goals were defined as the study of the relation between the value of the angle lambda and the fixation disparity quantified with the Rousseau test.

Relation between ocular dominance measured with the Guillon's test and the Hole-in-car test will also studied.
