Comparison between ophthalmological outcomes of eyes with and without vitreous floaters among patients with unilateral symptomatic eyes.
| Unilateral vitreous floaters | Symptomatic eyes with vitreous floater (n = 163) | Contralateral eyes without vitreous floater (n = 163) | P-value+ |
|---|---|---|---|
| BCVA (logMAR) | 0.06 ± 0.11 | 0.04 ± 0.08 | 0.09 |
| S.E. (D) | − 0.7 ± 2.2 | − 0.5 ± 1.9 | 0.02 |
| IOP (mmHg) | 14.7 ± 3.2 | 15.2 ± 3.0 | 0.02 |
| CMT (μm) | 259.4 ± 20.2 | 260.0 ± 19.5 | 0.56 |
| pRNFL (μm) thickness | 100.7 ± 11.6 | 100.5 ± 11.4 | 0.08 |
| pVO on UWF | 0.04 | ||
| None | 60 eyes (36.8%) | 133 eyes (81.6%) | |
| pVO | 103 eyes (63.2%) | 30 eyes (18.4%) | |
| PVD on SD-OCT (*) | (86 eyes total) | (86 eyes total) | < 0.001 |
| Stage 0 | 4 (4.7%) | 9 (10.5%) | |
| Stage 1 | 6 (6.9%) | 12 (13.9%) | |
| Stage 2 | 5 (5.8%) | 30 (34.9%) | |
| Stage 3 | 5 (5.8%) | 10 (11.6%) | |
| Stage 4 | 66 (76.7%) | 25 (29.1%) | |
*PVD was staged according to SD-OCT finding as Stage A (perifoveal), Stage B (macular PVD with vitreopapillary adhesion), and Stage C (complete PVD). The SD-OCT data for 53% (86 out of 163 eyes) were available.
+P-value was calculated using the Student t test for numerical values and Fisher exact test for categorical values.
BCVA best-corrected visual acuity, logMAR the logarithm of the minimal angle of resolution, S.E. spherical equivalents, D diopters, IOP intraocular pressure, CMT central macular thickness, pRNFL peripapillary retinal nerve fiber layer, pVO peripapillary vitreous opacity, UWF ultra-widefield scanning laser ophthalmoscopy, PVD posterior vitreous detachment, SD-OCT spectral domain-optical coherence tomography.
