Summary
Cutting an encircling band significantly improves pulsatile ocular blood flow (POBF) in eyes. This procedure restores blood flow without negatively impacting visual acuity or buckle height.
Area of Science:
- Ophthalmology
- Ocular Circulation
- Retinal Surgery
Background:
- Encircling bands are used in retinal detachment surgery.
- The impact of these bands on ocular hemodynamics is not fully understood.
Purpose of the Study:
- To investigate the effect of removing an encircling band on pulsatile ocular blood flow (POBF).
Main Methods:
- An interventional case series involving 27 eyes with encircling bands.
- Ocular pulse amplitude (OPA) and pulsatile ocular blood flow (POBF) were measured before and after band removal.
- Follow-up measurements were taken at 1 month, 3 months, and 1 year.
Main Results:
- Encircling bands reduced POBF to 43% of the fellow eye (P < 0.001).
- Cutting the band restored POBF to a mean of 85.6% of the fellow eye.
- No retinal detachment occurred, buckle height was minimally affected, and visual acuity remained stable.
Conclusions:
- Encircling bands significantly impair pulsatile ocular blood flow.
- Surgical removal of encircling bands effectively restores ocular blood flow without compromising surgical outcomes.
