“… 14 – 19 China is one of the most rapidly aging societies in the world, and the prevalence rate of ERM is estimated to be 7.3%–11.43%. 18 , 19 Moreover, with the adoption of the 23G system (a more refined vitrectomy system), and more sophisticated OCT instruments and staining techniques, 4 the prognosis for macular diseases treated with PPV has improved in recent years. Therefore, more patients with ERM and MH prefer PPV than conservative treatment, which is another reason for the increase in the rate of macular diseases treated with PPV.…”

BackgroundSeveral new instruments and techniques for pars plana vitrectomy (PPV) have been widely used in recent years, but information about the related characteristics of PPV in China is limited. To investigate the trends in the characteristics of PPV in Eastern China, an 8-year retrospective study was conducted.Patients and methodsWe collected data from patients who underwent PPV at the Eye, Ear, Nose and Throat Hospital of Fudan University, Shanghai, China, in November 2007, November 2011, and November 2015. Cases of trauma-related retinopathy were excluded. Data on the patient demographics, surgical procedures, and the prophylactic use of IOP-lowering medications were collected and analyzed.ResultsIn 2015, most PPVs were conducted with a 23-gauge system, whereas all PPVs in 2007 and 2011 were conducted with a 20-gauge system. The proportions of macular disease in the population in 2007, 2011, and 2015 were 9.1%, 10.7%, and 21.5%, respectively (P<0.001). The proportion of PPV that was combined with lens extraction and intraocular lens (IOL) implantation increased significantly from 12.81% in 2007 to 25.95% by 2015 (P<0.001). The proportions of patients treated with IOP-lowering drugs in 2007, 2011, and 2015 were 27.40%, 38.20%, and 12.60%, respectively (P<0.001). In 2007, systemic carbonic anhydrase inhibitors (CAI-Ss) and beta blockers (BBs) were the two main types of prophylactic IOP-lowering drugs administered, but their use had decreased in 2015 (P<0.001). The preventive use of adrenergic agonists (AAs), topical carbonic anhydrase inhibitors (CAI-Ts), and prostaglandin analogs (PGAs) became increasingly frequent from 2007 to 2015 (P<0.05).ConclusionThe 23-gauge system, rather than the 20-gauge system, had become the mainstream PPV instrument by 2015. The proportion of macular disease patients requiring PPV in China clearly increased, and the rate of prophylactic IOP-lowering drug use decreased by 2015.

“…However, almost 40% of the cases in that series had vitreomacular adhesion alone. In an urban Chinese population, Liu et al 11 reported a prevalence of 16.8% for any VRIA among adults without eye disease, excluding eyes with posterior vitreous detachment alone. Meuer et al 12 reported a prevalence of 39.7% for any VRIA, excluding macular and paravascular cysts, among the residents of Beaver Dam.…”

Vitreoretinal interface abnormalities in middle-aged adults with visual impairment in the UK Biobank study: prevalence, impact on visual acuity and associations

2017

ObjectiveThe aim of this study was to determine the prevalence of vitreoretinal interface abnormalities (VRIA), the degree of visual impairment and associations with VRIA among adults, aged 40–69 years, in the UK Biobank study.Methods and analysisColour fundus photographs and spectral domain optical coherence tomography images were graded for 25% of the 8359 UK Biobank participants with mild visual impairment or worse (LogMAR >0.3 or Snellen <6/12) in at least one eye. The prevalence and contribution of VRIA to visual impairment was determined and multinomial logistic regression models were used to investigate association with known risk factors and other predetermined socioeconomic, biometric, lifestyle and medical variables for cases and matched controls.ResultsThe minimum prevalence of any VRIA was 17.6% and 8.1% in the eyes with and without visual impairment, respectively. VRIA were identified as the primary cause of visual impairment in 3.6% of eyes. Although epiretinal membrane and vitreomacular traction were the most common VRIA, the degree of visual impairment was typically milder with these than with other VRIA. Visual impairment with a VRIA was positively associated with increasing age (relative risk ratio (RRR) 1.22 (95% CI 1.07 to 1.40)), female gender (RRR 1.28; 1.08 to 1.52) and Asian or Asian British ethnicity (RRR 1.60; 1.10 to 2.32).ConclusionsVRIA are common in middle-aged adults in the UK Biobank study, especially in eyes with visual impairment. VRIA were considered to be the primary cause of visual impairment in 3.6% of all eyes with visual impairment, although there was variation in the degree of visual impairment for each type of VRIA.

“…The prevalence of PVD is mainly affected by the age of the patients, but there are also other known risk factors including: greater eye length and myopia, aphakia, inflammatory diseases, eye traumas, and ocular surgery [11]. World literature provides data indicating a higher prevalence of PVD in patients with type 2 diabetes compared to non-diabetic patients [12,13]. The results of our study indicate that also prediabetes should be considered as a factor favouring the posterior vitreous detachment.…”
