Abstract Details

Purpose:

To report vitreoretinal interface abnormalities evaluated by spectral-domain optical coherence tomography (SD-OCT) and ocular ultrasonography (OUS) in patients with Asteroid Hyalosis (AH).

Setting:

Teaching hospital.

Methods:

Prospective study that included 14 eyes (12 patients) with confirmed diagnosis of AH. OUS and Macular SD-OCT scans (Heidelberg Engineering, Heidelberg, Germany) were obtained and the posterior vitreoretinal interface was examined.

Results:

In ten of fourteen AH eyes, SD-OCT revealed abnormal vitreoretinal abnormalities. In five eyes a epiretinal membrane was present, three eyes revealed a vitreomacular adhesion and two eyes vitreomacular traction. In three of these nine eyes, posterior vitreoschisis could be detected, and no clear posterior vitreous detachment (PVD) could be seen on OCT or OUH in the other six AH eyes.

Conclusions:

Vitreoretinal interface in AH patients commonly present vitreoretinal abnormalities. Complete PVD is uncommon in AH eyes and spontaneous PVD may lead to vitreoschisis and anterior-posterior traction.
