To investigate the prevalence of intraretinal hyperreflective lines (IHL) in eyes with vitreomacular adhesion.
A retrospective study in Ophthalmology Consult - Ophthalmology Department of the University of Health Science, Ankara Ulucanlar Eye Education and Research Hospital, Ankara, Turkey.
49 eyes of 49 patients with VMA were included. Spectral domain optical coherence tomography (SD-OCT) volume scans were analysed for the presence of a central vertical hyperreflective line. The sequential OCT images of the fellow eyes of patients with IHL were further studied to analyse the changes in vitreous interface status during the follow up period.
IHL was observed in 10 of 49 eyes (20.4%) of patients with vitreomacular adhesion (VMA). The vitreous interface status of patients with IHL included VMA (eight eyes) and posterior hyaloid detachment on foveal region (two eyes). In fellow eyes, 5 VMA, 2 vitreomacular traction (VMT), 2 full thickness macular hole (FTMH), 1 full thickness macular hole – rhegmatogenous retinal detachment (FTMH-RRD) were detected. At later periods, in the 2 eyes with VMA, lamellar and full-thickness macular hole developed. 5 of fellow eyes displayed IHL in the course of time.
The presence of IHL detected by SD-OCT in patients with VMA may indicate that posterior hyaloid firmly attached to the fovea. This in turn may reflect the onset of foveal dehiscence due to the structural changes on foveal architecture. The increase in the prevalence of vitreomacular interface disease (VMID) in fellow eyes of patients with IHL may require close follow up.
