Objective:
To explore the relationship between subfoveal choroidal thickness (SFCT) and persistent subretinal fluid (pSRF) at the macula after successful rhegmatogenous retinal detachment (RRD) surgery.
Methods:
This is a retrospective multicenter comparative study of Caucasian subjects with successful RRD repair. SFCT was measured in 2 groups: Group 1 with persistent subretinal fluid (pSRF) 1 month after repair, and Group 2 with absence of pSRF. SFCT was measured by a masked observer based on ImageJ. Multiple regression analyses were implemented to control for age, refraction, and gender.
Results:
Surgery type was as follows: Group 1 (24 scleral buckle SB, 23 pars plana vitrectomy PPV, 9 SB+PPV, and 5 pneumoretinopexy), and Group 2 (68 PPV). Adjusted mean 1-month SFCT was thicker in Group 1 than in Group 2 by 41.0 µm (p = 0.049). Within Group 1, PPV subgroup tended to have thinner SFCT than the other subgroups by: SB (117.4 µm), SB-PPV (9.3) and pneumoretinopexy (1.2 µm) (all p>0.05). SFCT at 1-month was not different between pSRF (237.5±77.2 µm) and no pSRF (213.7±72.1 µm) in PPV groups (p=0.2).
Conclusion:
SFCT post PPV appeared similar in eyes with or without pSRF. In eyes with pSRF, SFCT tended to be thicker following SB compared to PPV.
