Impact of prior pars plana vitrectomy on development of cystoid macular edema after uneventful cataract surgery

“…A large, retrospective database study showed that the incidence and relative risk of developing pCME within 3 months postoperatively was increased in subjects with a history of retinal detachment repair. 12 In patients with a history of PPV with gas or air tamponade, the incidence of pCME was reported to be 17.2%. 13 In line with these previous reports, our study found that the incidence of clinically significant, acute onset pCME in eyes with a history of PPV was 13%.…”

Intraoperative complications and visual outcomes of cataract surgery in patients with retinal vein occlusion: multicenter database study

“…It is believed that postoperative CME is caused by release of inflammatory mediators during phacoemulsification, which in turn increases vascular permeability. 7 Eyes with RVO have a compromised blood-retinal barrier and abnormalities in the structure of the retinal capillary networks. 8,9 These factors could explain why eyes with RVO are more susceptible to development of macular edema postoperatively than those without RVO.…”

“…The Caldicott Guardian, who oversees data protection, and lead clinician at each center gave approval for the data extraction. 7 This study was conducted in accordance with the tenets of the Declaration of Helsinki. The extracted patient information was deidentified and, therefore, was not classified as human subject research, and institutional board review approval was waived.…”

Macular edema after cataract surgery in diabetic patients evaluated by Spectral domain OCT at Thammasat eye center

“…1 Pseudophakic macular edema occurs commonly after cataract surgery, even in the absence of risk factors and complications. 2 The incidence of pseudophakic macular edema in previous studies varies between 0.20% to 20%. 3 In diabetic patients, postoperative macular edema is a complex and frequent encountered problem, especially in patients with preexisting diabetic retinopathy.…”
