Pars plana vitrectomy effectively improved vision in most Eales disease patients with vitreous hemorrhage or neovascular membranes. However, extensive disease and retinal detachment led to limited visual gains, suggesting earlier intervention is beneficial.

Area of Science:

  • Ophthalmology
  • Retinal Surgery

Background:

  • Eales disease is a rare condition characterized by inflammation and neovascularization in the retina.
  • Complications include persistent vitreous hemorrhage (PVH), traction retinal detachment (TRD), and neovascular membranes (NVM), often leading to significant vision loss.

Purpose of the Study:

  • To evaluate the efficacy of pars plana vitrectomy in managing complicated Eales disease.
  • To assess visual outcomes based on the extent of neovascularization and retinal detachment.

Main Methods:

  • Retrospective review of 47 patients (49 eyes) who underwent vitrectomy for Eales disease.
  • Patients were categorized into four subgroups based on PVH, optic disc NVM (NVD), peripheral NVM (NVP), or extensive NVM with long-standing TRD (ENV).

Main Results:

  • Postoperative visual acuity improved in most eyes with PVH, NVD, or NVP (mean acuity 0.32).
  • Eyes with extensive NVM and TRD (ENV) showed limited visual improvement (range 0.02-0.15).
  • Significant differences in visual outcomes were observed between the ENV subgroup and the other three subgroups (P < 0.01).

Conclusions:

  • Pars plana vitrectomy, combined with endolaser photocoagulation, can improve vision in the majority of Eales disease patients.
  • Extensive fibrovascular membranes and chronic retinal detachment are associated with poorer visual outcomes.
  • Early surgical intervention is recommended to prevent irreversible vision loss in Eales disease.
