Methods
This was retrospective study of consecutive SD OCT images of eyes with VMT or ERM examined in a retinal referral practice. No eye had known causes that induce or are associated with proliferative changes, such as retinal vascular disease, ocular inflammation, retinal tears, or retinal detachment.
An SD OCT system combined with a nonmydriatic fundus camera 3-D OCT 1000 (Topcon Corp, Tokyo, Japan) was used in our study. This system used a superluminescent diode with a center wavelength of 830 nm
Results
There were 53 eyes of consecutive 39 patients (16 men and 23 women; mean age, 69.3 years; range, 52 to 87 years). The visual acuity ranged from 20/20 to 3/400 (median, 20/30). Sixteen eyes had an implanted intraocular lens. VMT was seen in 12 eyes. The clinical characteristics of the eyes with focal and broad VMT are summarized in the Table.
Discussion
The SD OCT provided unprecedented 3-D visualization of the vitreomacular interface in eyes with VMT and idiopathic ERM. The relatively large volume imaged, 6 × 6 × 1.7 mm in each scan, enabled visualization and characterization of vitreomacular configurations. By means of 3-D imaging and measurement using SD OCT, we found the vitreous attachment in VMT could be split into two main categories, focal and broad, each with specific macular findings. Most of the eyes with VMT were found to have
