Background and objectives: Complications of Bales disease can cause visual
loss. Long term visual prognosis following vitrectomy for Bales disease com
plications has been studied. Patients and methods: Retrospective analysis o
f 64 eyes of 57 patients who underwent vitrectomy for Bales disease complic
ations with a minimum follow-up of 60 months. Results: 62.4% eyes at 2 mont
hs and 71.8% at 60 months had 6/60 or better visual acuity. Visual acuities
for individual cases were quite stable at the 60 month follow up with 50 e
yes (78.5%) either maintaining or improving upon their 2 month post operati
ve visual acuity. Conclusion: Visual acuity improves after vitrectomy in ma
jority of patients with Bales disease complications and remains stable on l
ong term follow-up.
