This study aimed to analyze the duration and causes of persistent subretinal fluid (PSF) after scleral buckle (SB) surgery in patients with macula-involving rhegmatogenous retinal detachment (RRD). Sixty-one eyes of 61 patients with macula-involving RRD who underwent SB surgery between 2016 and 2022 were reviewed retrospectively. PSF was confirmed on optical coherence tomography. The PSF duration after surgery and the analysis of relevant ocular and systemic factors were conducted according to the PSF duration. The mean duration of PSF was 5.9 ± 4.6 months in all eyes and 8.1 ± 5.0 months in eyes not treated with external subretinal fluid (SRF) drainage, which was significantly longer than 4.5 ± 3.7 months in those subjected to external SRF drainage. The mean best-corrected visual acuity improved significantly 3 months after surgery. There were significant visual improvements in the external SRF drainage group compared to the non-drainage group during all follow-up periods. Longstanding shallow RRD was significantly associated with longer PSF duration after SB surgery. External SRF drainage during SB surgery can effectively reduce SRF, shorten the duration of PSF, and accelerate visual improvement.

UI MeSH Term Description Entries
D012163 Retinal Detachment Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery. (Dorland, 27th ed; Newell, Ophthalmology: Principles and Concepts, 7th ed, p310-12). Retinal Pigment Epithelial Detachment,Detachment, Retinal,Detachments, Retinal,Retinal Detachments
D004322 Drainage The removal of fluids or discharges from the body, such as from a wound, sore, or cavity.
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons. Retrospective Study,Studies, Retrospective,Study, Retrospective
D012591 Scleral Buckling An operation for retinal detachment which reduces the size of the globe by indenting the sclera so that it approximates the retina. Buckling, Scleral,Bucklings, Scleral,Scleral Bucklings
D014792 Visual Acuity Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast. Acuities, Visual,Acuity, Visual,Visual Acuities
D014821 Vitrectomy Removal of the whole or part of the vitreous body in treating endophthalmitis, diabetic retinopathy, retinal detachment, intraocular foreign bodies, and some types of glaucoma. Vitrectomies
D058471 Subretinal Fluid An exudate between the RETINA and CHOROID from various sources including the vitreous cavity, SUBARACHNOID SPACE, or abnormal vessels. Intraretinal Fluid,Sub-Retinal Fluid,Fluid, Intraretinal,Fluid, Sub-Retinal,Fluid, Subretinal,Intraretinal Fluids,Sub Retinal Fluid
D041623 Tomography, Optical Coherence An imaging method using LASERS that is used for mapping subsurface structure. When a reflective site in the sample is at the same optical path length (coherence) as the reference mirror, the detector observes interference fringes. OCT Tomography,Optical Coherence Tomography,Coherence Tomography, Optical,Tomography, OCT
