Brief Summary:
The purpose of this study is to evaluate the prevalence of vitreomacular adhesion (VMA) in patients 40 years and older using Spectral Domain Optical Coherence Tomography.

Condition or disease
Vitreomacular Adhesion

Detailed Description:
As a function of age, liquefaction of the vitreous body results in separation of the vitreous cavity from the retina. This posterior vitreous separation may be incomplete, leading to areas of residual VMA. These adhesions can result in maculopathies such as vitreomacular traction syndrome, macular hole, epiretinal membrane, cystoid macular edema, diabetic macular edema, neovascularization in diabetic retinopathy and retinal vein occlusion, exudative age-related macular degeneration, and myopic traction maculopathy. VMA may lead to pathological sequelae due to the static and dynamic anteroposterior tractional forces to the surface of the macula. The resultant complication will depend on the size and strength of the traction, with smaller areas of adhesion leading to greater traction. Identifying the prevalence of vitreomacular adhesion and its associated complications will yield valuable, new epidemiologic data, leading to improved diagnosis and management of patients with this condition. The prevalence of vitreomacular adhesion in specific age groups has not been investigated.

Vitreomacular adhesion
Male or female subjects aged over 40 years with vitreomacular adhesion

Primary Outcome Measures :
  1. What is the overall prevalence of Vitreomacular adhesion in the population 40 years and older? [ Time Frame: Two years ]
    Prevalence will be measured using Spectral Domain Optical Coherence Tomography. Tomography scans will be evaluated for the presence or absence of vitreomacular adhesion.

Secondary Outcome Measures :
  1. Is there is a significant correlation between VMA and various maculopathies including diabetic macular edema, retinal vascular occlusion, and age-related macular degeneration? [ Time Frame: 2 years ]
    Spectral domain optical coherence tomography scans will be used to evaluate for the presence of isolated or concomitant vitreomacular adhesion.

Other Outcome Measures:
  1. Is VMA more common in males or females? [ Time Frame: 2 years ]
    The prevalence of VMA in both genders will be identified using Spectral Domain Optical Coherence Tomography and evaluated for statistical significance.
