Patients and Methods
Consecutive patients undergoing outpatient review at 6 weeks after pars plana vitrectomy surgery for uncomplicated primary rhegmatogenous retinal detachment were recruited to the study. Patients with preexisting macular pathologic features (e.g., age-related macular degeneration) likely to influence imaging and visual outcome were excluded from the study. Patients underwent best-corrected visual acuity assessment as measured on an Early Treatment of Diabetic Retinopathy Study chart, pin-hole
Results
One hundred patients were recruited to the study. Table 1 shows demographic data (type of retinal detachment, clock hours of detachment, etc.). At the 6-week investigation, 15 patients had persistent SRF on OCT (Table 2). Patterns of SRF were defined according to those noted in our previous investigation on scleral buckle patients as either confluent fluid, single, or multiple blebs (Benson et al, unpublished data). In this study, we noted that most of those affected had a single bleb of fluid,
Discussion
Optical coherence tomography can detect SRF not appreciated on clinical examination in patients having undergone vitrectomy and gas procedures for retinal detachment. Subretinal fluid was seen in 15 of 100 patients at 6 weeks, was associated with worse VA at this time point, and was seen clinically in only 8 of these 15. The presence of fluid did not seem to be associated with the patient demographics or characteristics of retinal detachment other than macular involvement.

2021, Photodiagnosis and Photodynamic TherapyCitation Excerpt :Changes in choroidal nutrition can cause damage to the retina, RPE, and optic nerve [17]. In addition, the macula can be affected by surgeries such as cataract and retinal surgery, as well as by various vascular and inflammatory diseases [18–21]. Due to the close relationship between the choroid and the retina, conditions that affect the macula can be expected to affect the choroidal layer as well.
