Vitreous Hyper Reflective Dots in Association With Pseudophakic Cystoid Macular Edema

The aim of this study is to assess the association between vitreous hyper-reflective dots (VHD) and the macular thickness changes following uneventful phacoemulsification. In this prospective study the investigators performed optical coherence tomography (OCT) imaging in patients undergoing cataract surgery preoperatively and postoperatively after 1 week, 1 month and 3 months and analyzed the OCTs for VHDs. The investigators then measured the macular thickness in patients with VHDs and without VHDs and correlated the macular thickness with the number of VHDs.
