Vitreomacular traction (VMT) is a condition characterized by an incomplete posterior vitreous detachment resulting in traction on the macula and decreased visual acuity. The process of vitreomacular traction can lead to a number of maculopathies including cystoid macular edema, epiretinal membranes, and macular holes. VMT is more common in patients over 40 years of age; however no population-based studies documenting the prevalence of VMT in this age group has been published. Purpose: The current study was undertaken to evaluate the prevalence of vitreomacular traction syndrome in the population aged above 40. Clinical examination does not adequately illustrate the extent of vitreomacular adhesion; therefore, Optical Coherence Tomography (OCT) was used to determine the presence of VMT. High-definition OCT has provided new insight into vitreomacular traction syndrome by allowing for better visualization of the tractional forces at the vitreoretinal interface. This investigation will analyze the vitreomacular interface with regard to VMT in correlation to age through use of the Spectral Domain OCT. Methods: One hundred and thirty-one eyes of 67 patients (36 females/31 males) were examined by optical coherence tomography (OCT). OCT was performed to obtain high-resolution cross-sectional images of the vitreoretinal interface in the posterior fundus. Results: The status of the posterior vitreoretinal interface was evaluated as follows; (1) Intact Vitreous- No posterior vitreous abnormality is depicted on OCT. (2) Vitreomacular adhesion/incomplete PVD- the posterior vitreous is partially attached and can be seen in contact with the macula on OCT. (3) Vitreomacular traction- the posterior vitreous is partially adhered to the inner retina resulting in distortion of the retinal architecture. (4) Complete posterior vitreous detachment, indicating no contact between the vitreous and retina. Conclusion: OCT results found no vitreous abnormality in 39.7% of all eyes; PVD in 6.87% of eyes, VMA in 51.1% of eyes, and VMT in 2.29% of eyes. Age was a significant risk factor to the development of VMT, while gender was not. As age increases, the probability of having VMT increases by 1.2%. Due to the association between vitreomacular traction and a variety of maculopathies, recognition and diagnosis of this entity is crucial. High definition OCT has allowed for outstanding visualization of the vitreomacular interface, which has allowed for a better understanding of this entity.
