Purpose
The study aims to observe the spontaneous remission of posterior vitreous detachment (PVD)-type vision degrading myodesopsia (VDM) during long-term follow-up.
Methods
We retrospectively reviewed VDM patients with PVD type that refused any treatment. The ratio and time of significant spontaneous remission of floater symptoms occurring were described. The associated factors with significant remission of floater symptoms were analyzed in the univariate and multivariate logistic regression analyses.
Results
In total, 179 patients with VDM were assessed. The mean age of all patients was 60.56 ± 0.47 years old, and the mean duration of follow-up was 23.89 ± 6.63 months. Of the patients, 40.78% have significant improvement in their floater symptoms after mean 16.55 ± 10.63-month follow-up. Myopia (OR = 0.280, 95% CI = 0.084–0.932, P = 0.038), the number of floaters > 3 (OR = 0.343, 95% CI = 0.172–0.683, P = 0.002), and floaters with string-like pattern (OR = 0.370, 95% CI = 0.166–0.824, P = 0.015) and blocky pattern (OR = 0.299, 95% CI = 0.090–0.993, P = 0.049) were negatively correlated with the significant spontaneous remission of VDM symptoms in the multiple binary logistic regression analysis.
Conclusions
Approximately 40% of VDM patients with PVD may experience significant spontaneous remission during long-term follow-up. Patients that are non-myopic and with fewer floaters are more likely to feel relief from VDM symptoms. Floaters with string-like or blocky patterns are less likely to undergo spontaneous remission.
