Vitreous Hyper Reflective Dots in Association With Pseudophakic Cystoid Macular Edema

Prospective Analysis of the Correlation Between Hyperreflective Dots in the Vitreous Body and the Appearance of a 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.

Inclusion Criteria:

• patients undergoing cataract surgery
• minimum age 18 years
• phacoemulsification technique
• subsequent implantation of a monofocal hydrophobic acrylic intraocular lens

Exclusion Criteria:

• intraoperative complications including capsule rupture with or without anterior vitrectomy
• iris bites
• previous interventions including vitrectomy
• glaucoma surgery
• exudative or dry age-related macular degeneration
• presence of diabetes
• history or presence of retinal vein occlusion or uveitis
• epiretinal glioses
