Project description:PurposeTo investigate the molecular composition of subretinal fluid (SRF) in central serous chorioretinopathy (CSCR) and rhegmatogenous retinal detachment (RRD) using proteomics and metabolomics.MethodsSRF was obtained from one patient with severe nonresolving bullous CSCR requiring surgical subretinal fibrin removal, and two patients with long-standing RRD. Proteins were trypsin-digested, labeled with Tandem-Mass-Tag and fractionated according to their isoelectric point for identification and quantification by tandem mass spectrometry. Independently, metabolites were extracted on cold methanol/ethanol, and identified by untargeted ultra-high performance liquid chromatography and high-resolution mass spectrometry. Bioinformatics analyses were conducted.ResultsIn total, 291 proteins and 651 metabolites were identified in SRF samples. Compared with RRD, 128 proteins (77 downregulated; 51 upregulated) and 76 metabolites (43 downregulated; 33 upregulated) differed in the SRF from CSCR. Protein and metabolites notably deregulated in CSCR were related to glycolysis/gluconeogenesis, inflammation (including serum amyloid P component, versican), alternative complement pathway (complement factor H and complement factor H-related protein), cellular adhesion, biliary acid metabolism (farnesoid X receptor/retinoid X receptor), and gluco- and mineralocorticoid systems (aldosterone, angiotensin, and corticosteroid-binding globulin).ConclusionsProteomics and metabolomics can be performed on SRF. A unique SRF sample from CSCR exhibited a distinct molecular profile compared with RRD.Translational relevanceThis first comparative multiomics analysis of SRF improved the understanding of CSCR and RRD pathophysiology. It identified pathways potentially involved in the better photoreceptor preservation in CSCR, suggesting neuroprotective targets that will require additional confirmation.

Project description:The purpose of the study is to report a case of peripheral exudative hemorrhagic chorioretinopathy (PEHCR), managed surgically with favorable visual outcome. A 66-year-old female presented with painless visual loss due to dense vitreous and subretinal hemorrhage extending from the far periphery to the macula. Pars plana vitrectomy (PPV) with subretinal tissue plasminogen activator (TPA) injection was performed resulting in good anatomical and visual outcome. PEHCR can present with severe visual loss. Surgical management with PPV and subretinal TPA injection might result in favorable anatomical and visual outcome.

Project description:Background To determine the incidence and characteristics of the multiple subretinal particles (SRPs) present after pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). Methods The medical records of 224 eyes of 224 patients that underwent PPV for RRD were reviewed. The presence of SRPs in the subretinal fluid blebs and the presence of subretinal deposits were determined by optical coherence tomography (OCT) and fundus autofluorescence (FAF). The characteristics of the FAF and infrared reflectance (IR) images of a scanning laser ophthalmoscope in eyes with SRPs (SRPs group) were compared to that of eyes without SRPs (control group). Results SRPs were observed in 27 eyes (12%), and they were completely resolved in 20 eyes (74%) after 6 months. The incidence of macula-off RRD (85%) and preoperative precipitates (41%) were significantly higher in the SRPs group than that in the control group (64%, P = 0.046; 12%, P = 0.002). The axial length was significantly shorter in the SRPs group than that in the control group (25.04 ± 1.54 mm, 26.00 ± 1.78 mm, P = 0.012). The preoperative and postoperative best-corrected visual acuity were not significantly different between the two groups (P = 0.702, P = 0.337). The subretinal fluid bleb determined by OCT were hyperfluorescent in the FAF images in 24 eyes (89%), and the subretinal deposits were hypofluorescent with solid appearance by OCT other than fluid in 3 eyes (11%). The hypofluorescent subretinal deposits in the FAF images were bright in the IR images in 2 eyes. Conclusions The SRPs consist of lipofuscin-related hyperfluorescent subretinal fluid and the subretinal deposits containing bright IR melanin particles of proliferating retinal pigment epithelial cells.

Project description:BackgroundMachine learning was used to predict subretinal fluid absorption (SFA) at 1, 3 and 6 months after laser treatment in patients with central serous chorioretinopathy (CSC).MethodsThe clinical and imaging data from 480 eyes of 461 patients with CSC were collected at Zhongshan Ophthalmic Center (ZOC) and Xiamen Eye Center (XEC). The data included clinical features from electronic medical records and measured features from fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), optical coherence tomography angiography (OCTA), and optical coherence tomography (OCT). A ZOC dataset was used for training and internal validation. An XEC dataset was used for external validation. Six machine learning algorithms and a blending algorithm were trained to predict SFA in patients with CSC after laser treatment. The SFA results predicted by machine learning were compared with the actual patient prognoses. Based on the initial detailed investigation, we constructed a simplified model using fewer clinical features and OCT features for convenient application.ResultsDuring the internal validation, random forest performed best in SFA prediction, with accuracies of 0.651±0.068, 0.753±0.065 and 0.818±0.058 at 1, 3 and 6 months, respectively. In the external validation, XGBoost performed best at SFA prediction with accuracies of 0.734, 0.727, and 0.900 at 1, 3 and 6 months, respectively. The simplified model showed a comparable level of predictive power.ConclusionsMachine learning can achieve high accuracy in long-term SFA predictions and identify the features relevant to CSC patients' prognoses. Our study provides an individualized reference for ophthalmologists to treat and create a follow-up schedule for CSC patients.

Project description:PurposeTo assess the efficacy of photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (cCSC), in whom subretinal fluid (SRF) was solely present outside the foveal area.MethodsIn this retrospective study, 16 eyes of 15 cCSC patients who received half-dose PDT because of notable subjective visual complaints due to the presence of extrafoveal SRF, were included. An ophthalmic examination was performed before treatment, including Early Treatment Diabetic Retinopathy Study best-corrected visual acuity measurement, applanation tonometry, slit-lamp examination, and indirect ophthalmoscopy, followed by multimodal imaging, including fundus photography, fundus autofluorescence, spectral-domain optical coherence tomography (OCT), enhanced-depth imaging OCT of the choroid, fluorescein angiography, and indocyanine green angiography.ResultsIn 7 treated patients (47%), PDT led to a decrease in visual complaints at the first evaluation visit. At this visit, extrafoveal SRF on OCT had resolved in 14 eyes (88%), whereas a complete resolution of extrafoveal SRF had occurred in all eyes at final follow-up visit. At baseline, posterior cystoid retinal degeneration was also present in 5 eyes (31%) and this remained present at all evaluation visits in these patients. Choroidal thickness decreased statistically significantly in the treated eyes, both foveally and at the location of the maximum height of extrafoveal SRF. No complications of PDT were observed.ConclusionsHalf-dose PDT treatment of cCSC patients with visual complaints due to extrafoveal SRF accumulation is a safe procedure leading to complete SRF resolution, a decrease in choroidal thickness, and a reduction in visual symptoms.

Project description:To investigate hemodynamic changes in macula-off rhegmatogenous retinal detachment (RRD) and its impact on visual prognosis by comparing with central serous chorioretinopathy (CSC). Using optical coherence tomography angiography (OCTA), vascular density in the superficial capillary plexus and deep capillary plexus (DCP) was retrospectively compared with that in contralateral unaffected eyes in macula-off RRD and CSC eyes. In RRD eyes, pre- and postoperative ultra-widefield (UWF) fluorescein angiography (FA) were obtained to analyze vascular changes. In OCTA, both macula-off RRD and CSC eyes showed less density in macular DCP, compared to the unaffected fellow eyes. Compared to CSC, eyes affected by macula-off RRD showed a reduction in DCP vascular density and an increase in foveal avascular zone area, although it had a much shorter macular detachment period. In macula-off RRD, less density of DCP was strongly correlated with longer duration of detachment, greater ellipsoid zone disruption, and poor visual recovery. In UWF-FA, detached retina showed capillary hypoperfusion, venous stasis and leakage, which were improved after reattachment. In conclusion, macular capillary loss of flow, which was associated with photoreceptor disruption, correlated with duration of detachment in RRD. Early reattachment and reperfusion are required for minimizing macular vasculature and photoreceptor damage in macula-off RRD.

Project description:PurposeTo describe the clinical course of a patient with persistent subretinal fluid (SRF) after primary scleral buckle surgery for a rhegmatogenous retinal detachment (RRD) repair who was subsequently treated with oral eplerenone for resolution of SRF.ObservationsA 34 year-old-male presented with a large bullous macula-involving RRD of unknown duration and underwent primary scleral buckle and retinotomy for drainage of subretinal fluid (SRF). His post-operative course was characterized by persistent macular SRF for 1.5 years with poor vision largely unchanged from his pre-operative presentation. Patient declined additional surgical treatment and opted for conservative management. Given such persistent SRF, the patient was trialed on a course of oral eplerenone 50 mg po bid. After only one month on this therapy, a marked decline in SRF was noted with near complete resolution after two months.Conclusions and importanceTo our knowledge, this is the first report of its kind to show the effectivity of oral eplerenone treatment in the reduction of SRF following retinal detachment surgery.

Project description:BackgroundTo compare the safety and efficacy of Ab-externo subretinal bands removal in comparison with the classical Ab-interno approach during pars plana vitrectomy for primary rhegmatogenous retinal detachment.MethodsSubjects aged 28-62 years with primary RRD complicated by proliferative vitreoretinopathy (PVR) with subretinal bands interfering with retinal flattening were treated by pars plana vitrectomy (PPV) and silicone oil injection. Subretinal bands were removed using the classical AB interno approach through one or more retinotomies in ten patients (group A) and using AB externo approach in twenty cases (group B). Post-operative follow-up visits occurred at 1 day, 1 week, 1 month, and 3 months, after surgery. The main outcomes were assessment of subretinal bands removal efficacy, documentation of complications, anatomical reattachment rate, and postoperative best-corrected visual acuity (BCVA).ResultsThere was no statistically significant difference between both groups regarding patients' age, gender, lens status, and the onset of retinal detachment. Seventy percent of both groups presented with inferior retinal detachment while ten percent presented with temporal detachments and twenty percent had a total retinal detachment. Both groups had a statistically significant improvement in postoperative visual acuity in comparison with preoperative visual acuity (P = 0.005 for group A and P = < 0.001 for group B). There was no statistically significant difference between both groups regarding preoperative (P = 0.928) and postoperative (P = 0.185) visual acuity. A higher incidence of complications was reported in group A (40%) in comparison with group B (30%) but this difference was not statistically significant (P = 0.69). More Epimacular membranes were seen postoperatively in group A (30%) in comparison with group B (20%) but again this difference was not statistically significant (P = 0.657). Subretinal hemorrhage was seen in ten percent of cases in both groups. Intraocular pressure was measured in every follow-up of all patients in both groups, no statistically significant difference was found between both groups.ConclusionsBoth techniques are effective and safe to remove subretinal bands with similar outcomes.

Project description:PurposeTo study the proteome of the subretinal fluid (SRF) from rhegmatogenous retinal detachment (RRD) in search for novel markers for improved diagnosis and prognosis of RRD.MethodsHuman undiluted SRF obtained during vitrectomy for primary RRD using a 41-gauge needle (n = 24) was analyzed and compared to vitreous humor from 2-day postmortem eyes (n = 20). Sample preparation underwent nanoflow liquid chromatography-tandem mass spectrometry. Label-free quantification (LFQ) using MaxQuant was used to determine differentially expressed proteins between SRF and vitreous humor. The intensity-based absolute quantification (iBAQ) was used to rank proteins according to their molar fractions within groups. Identification of proteins beyond the quantitative level was performed using the Mascot search engine.ResultsThe protein concentration of the control vitreous humor was lower and more consistent (1.2 ± 0.4 mg) than that of the SRF (17.9 ± 22 mg). The iBAQ analysis showed high resemblance between SRF and vitreous humor, except for crystallins solely identified in vitreous humor. The LFQ analysis found 38 protein misregulations between SRF and vitreous humor of which the blood coagulation pathway was found to be enriched using the PANTHER Classification System. Combined, the iBAQ, LFQ, and Mascot analysis found an overlap only in chitinase-3-like protein 1 and galectin-3-binding protein unique to the SRF.ConclusionsThe proteome of the SRF was highly represented by proteins involved in proteolysis. Such proteins can possibly serve as targets in modulating the effects of SRF in RD.Translational relevanceTo identify potential novel biomarkers for therapeutic targeting in RD.
