“…The results of this study did not identify a difference between women and men for the prevalence of VMT due to the limited study cohort. The Beijing Eye Study [20] reported a slightly higher prevalence of VMT of 2.4% in a Chinese population aged >50 years. This prevalence increased with age and was higher in women than in men.…”

“…While the prevalence [14,15,16,17,18] and incidence [19] of MH in the general population is well documented, there are few data available on the prevalence of VMA and traction amongst the general population [20,21]. A diagnosis of VMI conditions is often only made at an advanced stage, when patients are experiencing the visual burden of the later stages of the disease.…”

Purpose: The primary objective of this study was to determine the prevalence of vitreomacular interface (VMI) changes on optical coherence tomography (OCT) in the general population. Second, other OCT changes were described. Methods: Abnormalities in the VMI were diagnosed by OCT scan and graded according to the International Vitreomacular Traction Study (IVTS) Group classification and subdivided into 3 grades according to John et al. [Retina 2014;34:442-446]. Results: The estimated prevalence of vitreomacular abnormalities within a Belgian population aged ≥50 years was 1.17% [confidence interval (CI 0.38-3.62)] for focal vitreomacular traction (VMT) grade 1; 0.39% (CI 0.05-2.76) for focal VMT grade 2; 8.17% (CI 5.33-12.53) for focal vitreomacular adhesion, and 17.9% (CI 13.41-23.9) for broad vitreomacular adhesion. Conclusion: The prevalence of vitreomacular abnormalities within a Belgian study cohort was reported. These results closely match previously reported data on the prevalence of VMT. Correct knowledge of the epidemiology of VMI disorders and early diagnosis will enable adequate intervention.

“…There are no published incidence studies of VMT to compare with, but the Beijing Eye study did use OCT to evaluate the completeness of PVD and found a prevalence figure of 2.3% with incomplete PVD. 17 The prevalence of symptomatic VMT in patients with and without coexisting pathology was estimated by Jackson et al 18 to be 0.35%. This discrepancy may not only be due to Jackson et al using combined numbers from smaller trials in tertiary referral centres compared with our general hospital setting but may also be due to the inevitable discrepancy in classification of VMA and VMT.…”

Aim Identify the incidence of vitreomacular traction (VMT) and frequency of reduced vision in the absence of other coexisting macular pathology using a pragmatic classification system for VMT in a population of patients referred to the hospital eye service. Methods A detailed survey of consecutive optical coherence tomography (OCT) scans was done in a high-throughput ocular imaging service to ascertain cases of vitreomacular adhesion (VMA) and VMT using a departmental classification system. Analysis was done on the stages of traction, visual acuity, and association with other macular conditions. Results In total, 4384 OCT scan episodes of 2223 patients were performed. Two hundred and fourteen eyes had VMA/VMT, with 112 eyes having coexisting macular pathology. Of 102 patients without coexisting pathology, 57 patients had VMT grade between 2 and 8, with a negative correlation between VMT grade and number of Snellen lines (r ¼ À 0.61717). There was a distinct cutoff in visual function when VMT grade was higher than 4 with the presence of cysts and sub retinal separation and breaks in the retinal layers. Conclusions VMT is a common encounter often associated with other coexisting macular pathology. We estimated an incidence rate of 0.01% of VMT cases with reduced vision and without coexisting macular pathology that may potentially benefit from intervention. Grading of VMT to select eyes with cyst formation as well as hole formation may be useful for targeting patients who are at higher risk of visual loss from VMT.

“…Aunque la prevalencia [14][15][16][17][18] y la incidencia [19] de los AM en la población general se encuentran bien documentados se disponen de pocos datos sobre la prevalencia de la AVM y la TVM en la población general [20,21] . El diagnóstico de las enfermedades en la IVM a menudo se realiza tan solo en estadios avanzados, cuando los pacientes experimentan la carga de la enfermedad sobre la vista en las últimas etapas de la enfermedad.…”

Objetivo: El objetivo principal del presente estudio consistió en determinar la prevalencia de los cambios en la interfase vitreomacular (IVM) mediante tomografía de coherencia óptica (OCT) en la población general. En segundo lugar, se describieron otros cambios de la OCT. Métodos: Las anomalías en la IVM se diagnosticaron mediante OCT y se distribuyeron de acuerdo con la clasificación del grupo International Vitreomacular Traction Study (estudio internacional de tracción vitreomacular, IVTS, por sus siglas en inglés) y se dividieron en 3 grados según John et al. [Retina 2014;34:442-446]. Resultados: La prevalencia calculada de anomalías vitreomaculares en la población belga de ≥50 años fue del 1,17% [intervalo de confianza (IC 0,38-3,62)] en el caso de tracción vitreomacular (TVM) focal de grado 1; del 0,39% (IC 0,05-2,76) en el caso de TVM focal de grado 2; del 8,17% (IC 5,33-12,53) en el caso de adhesión vitreomacular focal; y del 17,9% (IC 13,41-23,9) en el caso de adhesión vitreomacular difusa. Conclusiones: Se presentó la prevalencia de anomalías vitreomaculares en un estudio de cohortes belga. Estos resultados concuerdan en gran medida con los datos presentados previamente sobre la prevalencia de la TVM. Un conocimiento correcto sobre la epidemiología de las alteraciones en la IVM y un diagnóstico temprano permitirán una intervención satisfactoria.
