Both scleral buckling and vitrectomy surgeries for retinal detachment impact choroidal perfusion, potentially affecting optic nerve head blood flow. Further research is needed to understand long-term consequences.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Retinal Diseases

Background:

  • Retinal detachment is a serious condition requiring surgical intervention.
  • Scleral buckling and vitrectomy are common surgical procedures for retinal detachment.
  • Choroidal perfusion is critical for retinal health and optic nerve function.

Purpose of the Study:

  • To evaluate the impact of scleral buckling and vitrectomy on choroidal perfusion.
  • To compare the effects of these two surgical techniques on ocular blood flow.

Main Methods:

  • The study included 17 patients with rhegmatogenous retinal detachment.
  • Seven patients underwent scleral buckling, and 10 underwent vitrectomy.
  • Choroidal perfusion was assessed using the pOBF Langham system before and after surgery, with the fellow eye as a control.

Main Results:

  • Scleral buckling showed a mean change in choroidal perfusion of 470 (355.32) microl/min.
  • Vitrectomy resulted in a mean difference of 254.2 (132.53) microl/min.
  • Both procedures demonstrated a statistically significant difference in choroidal perfusion compared to the control eyes.

Conclusions:

  • Both scleral buckling and vitrectomy significantly alter choroidal perfusion.
  • These surgical interventions may potentially impair blood supply to the optic nerve head.
  • Understanding these hemodynamic changes is crucial for managing patients with retinal detachment.
