Abstract: : Purpose:To describe the variation in ocular biometry and age in adults having spontaneous posterior vitreous detachment. Methods: A prospective observational case series study of subjects presenting acute posterior vitreous detachment (PVD) of less than 3 months duration. Diagnosis of PVD was established using 10–Mhz B–scan ultrasound and fundus biomicroscopy. Axial length (AL) was measured using A scan mode. Results: A total of 127 subjects were eligible for the survey of whom 43 were men and 84 were women. Mean ALs were 23,412 ± 0,97 in men and 22,89± 1,11 in women. (p=0,01). The mean age at presentation was 68,05 ± 5,46 in men and 63,95 ± 7,05 in women (p=0,001). Data analysis excluding subjects having ALs greater than 26 mm. did not show correlation between AL and age of presentation of PVD. Conclusions: We found that PVD occurs earlier during life–time in women than in men despite presenting shorter axial lengths. Female gender may be more determinant than axial length alone for the occurrence of PVD Refractive measures using diopters may not be adequate for evaluation of risk factors associated to PVD.
