Visual outcomes of early and late vitrectomy for breakthrough vitreous hemorrhage associated with exudative age-related macular degeneration and polypoidal choroidal vasculopathy.

To compare the visual outcomes of early and late vitrectomy for breakthrough vitreous hemorrhage (VH) associated with exudative age-related macular degeneration (exudative AMD) and polypoidal choroidal vasculopathy (PCV). A retrospective chart review was performed with data of all patients diagnosed with exudative AMD and PCV-related breakthrough VH who underwent early or late vitrectomy (within or after 3 months, respectively). Demographic data and best-corrected visual acuity (BCVA) at baseline, and 1, 3, 6, and 12 months postoperatively were recorded and analyzed. Overall, 105 eyes with breakthrough VH were examined and categorized in either the early or late vitrectomy group. In the early and late vitrectomy group, LogMAR BCVA improved from 2.15 ±â€…0.08 and 2.07 ±â€…0.14 at baseline to 1.26 ±â€…0.09 and 1.27 ±â€…0.14 at 12 months, respectively (P < .001). Between early and late vitrectomy, the PCV subgroup demonstrated improved LogMAR BCVA at 1 year, but there was no statistically significant (P = .754). Conversely, the LogMAR BCVA improvement at 1 year in the early vitrectomy group demonstrated statistically significant differences from the late vitrectomy group (P = .025) in the exudative AMD subgroup. Both, early and late vitrectomy can improve visual acuity in patients with breakthrough VH secondary to exudative AMD and PCV. However, early vitrectomy is more beneficial for breakthrough VH-associated exudative AMD.
