Abstract
Purpose :
To investigate the changes in choroidal thickness (CT) in the macular areas of patients with rhegmatogenous retinal detachment after scleral buckle surgery using enhanced depth imaging optical coherence tomography.
Methods :
78 Patients with rhegmatogenous retinal detachment and relatively healthy vitreous body who had the indication to take scleral buckle surgery were included in this study. Choroidal thickness in the macula area was measured with enhanced depth imaging optical coherence tomography at baseline, 1 month, and 6 months after scleral buckle surgery.
Results :
The mean subfoveal CT increased significantly at 1 month (335.0 ± 81.6 mm, P <0.001) after scleral buckle surgery and then decreased when compared with baseline (312.2 ± 68.1 mm). The subgroup analysis showed similar trends of CT changes in patients with or without subretinal fluid. The mean change in CT was statistically significantly correlated with the mean change in best-corrected visual acuity and MP-1 results after scleral buckle surgery.
Conclusions :
In patients with rhegmatogenous retinal detachment, the mean CT increased significantly in the macular area in the early stage after scleral buckle surgery. This may be the result of reversible subclinical microcirculatory dysfunction of the choroid. The results might reflect a redistribution of choroidal blood flow, which may effect in retinal reattachment and vision prognosis of the patients.
