Three-dimensional foveal shape changes after asymptomatic macular posterior vitreous detachment

To show a case in which the shape of the fovea changed after an asymptomatic macular posterior vitreous detachment (PVD).

The foveal shape was determined from the spectral-domain optical coherence tomography (OCT) images before and after a spontaneous macular PVD.

A 66-year-old man with a unilateral macular hole in the right eye presented with a perifoveal PVD in the asymptomatic left eye. One year later, the left eye developed a macular PVD, and OCT measurements showed a 16.7% decrease in the central foveal thickness, and increases in the pit depth by 20.5%, foveola diameter by 14.7%, and pit volume by 19.4%. The thicknesses of the macular subfields of the Early Treatment Diabetic Retinopathy Study were decreased by 13.0% in the central subfield and by 1.4%-6.6% in the other subfields.

The deepening and widening of the fovea after a macular PVD indicate that a PVD can alter the shape of the fovea.
