title: [Prospective study of 163 retinal detachments operated by episcleral technique (preoperative examination)].
abstract: The predominance of retinal breaks in the superior temporal quadrant is well known. This predominance was found to be related to age and refraction (p < 0.01). The distribution of breaks plotted across the 12 meridians shows a predilection for the superior temporal quadrant and half of the inferior temporal and superior nasal one. However, in this area the distribution is irregular (p >> 0.001) with a predominance in the 10-11 and 12-1 o'clock section (if we consider the right eye). The H/T ratio (holes/tears for each case) is positive for patients under 40 years of age and becomes negative after 50 years.
