This 66YO female was examined following successful vitrectomy three months earlier for a macula-off, rhegmatogenous retinal detachment (RRD). Vision improved from a preoperative 20/200 to 20/40 postoperatively.
OCT scanning shows multifocal areas of intraretinal and subretinal fluid (SRF). Four months later, vision remains at 20/40, and all areas of the SRF are shrinking.
Learning Points:
Loculated fluid, which represents an area of persistent subclinical SRF in the presence of a clinically reattached retina, is seen postoperatively in up to 15% of RRD following vitrectomy (Retina 2020;40:1153-1159), and eventually resolves after many months of observation.
In a post hoc analysis of the PIVOT trial, there were no differences in the incidence of loculated fluid between vitrectomy and pneumatic retinopexy (BJO 2021-320981, ahead of print). Although subfoveal loculated fluid was associated with reduced visual acuity at 3 months, vision eventually was similar to that of those without fluid at 1 year.
Bansal et al described the en face findings for loculated fluid (Ophthalmology Retina 2023;7:496-502), which prompted us to perform en face imaging in this patient.
In our practice, we continue to find that en face imaging often provides a unique and compelling perspective on a variety of pathologies, and we hope other clinicians will add it to their daily clinical routine.
