Background: Acute central serous chorioretinopathy (CSCR), with subretinal fluid (SRF) resolving spontaneously within a few months from disease onset, has been considered as a benign and self-limiting disease for many years. This study sought to discover if a short presence of SRF can result in morphological and functional damage to the retina. Materials and methods: The study included patients treated by subthreshold diode micropulse laser (SDM) application for acute CSCR at the Dobry Wzrok Ophthalmological Clinic between January 2018 and November 2019. Inclusion criteria were: first episode of CSCR; duration of symptoms of two months or less; complete resolution of subretinal fluid (SRF) after a single session of SDM; and a lack of any retinal pathology, previous CSCR episode, significant anisometropia or amblyopia in the collateral eye. Fifteen patients fulfilled the inclusion criteria, including 13 males and two females aged 42.3 ± 9.5 years. The mean duration of symptoms before treatment was 4.7 ± 1.3 weeks on average. Baseline and follow-up examinations were performed in both the affected and collateral eyes and included best-corrected visual acuity (BCVA); spectral-domain optical coherent tomography measurements such as central retinal thickness (CRT) and minimal foveal thickness (MFT) (at the follow-up visit only); fluorescein angiography (at presentation only) and fundus autofluorescence. The first follow-up visit, when the total resolution of SRF was noted, was conducted between 8 and 12 weeks after SDM. Results: Resolved CSCR eyes had significantly poorer BCVA, CRT, and MFT findings in comparison with healthy collateral eyes (respectively, 0.11 +/− 0.1 vs. 0.01 +/− 0.04 logMAR; 238.80 +/− 23.39 vs. 264.87 +/− 21.22 µm and 178.93 +/− 16.88 vs. 199.47 +/− 17.87 µm) despite the short period of CSCR duration (maximum of 14 ± 2.15 weeks on average). Conclusion: Short presence of SRF typical for acute CSCR can affect retinal function and morphology resulting in poorer visual outcome.

Abstract Background Subthreshold microsecond pulsing laser is an increasingly common treatment approach for central serous chorioretinopathy. However, there is no literature available on the safety of microsecond laser using different fluence settings in this disease. While many publications can be obtained from conventional microsecond pulsing lasers, few parameter sets are published with the navigated microsecond pulsing laser. Therefore, this study aims to investigate the safety of different parameter sets in subthreshold microsecond pulsing laser treatments. Methods In this retrospective chart review, consecutive patients with central serous chorioretinopathy (> 3 months duration of symptoms) treated with navigated subthreshold microsecond pulsing laser and a follow up of at least five months after microsecond laser application were included. For each patient, the treatment parameters, plan layout, and adverse events related to laser were evaluated. Secondary outcomes included best-corrected visual acuity and anatomical improvements (central retinal thickness). Results One hundred and one eyes were included in the observation and followed for a mean of 10 months (range 5–36). Although a larger range of parameter sets and fluence settings have been used, no patient demonstrated adverse events from navigated microsecond pulsing laser. While 88% of the cases demonstrated stability, 13 cases lost five or more letters due to the persistence of the subretinal fluid. In mean, a best-corrected visual acuity improvement of 0.07logMar (± 0.2) was seen (p = 0.02). In 51% of the patients, a statistically significant improvement of the central retinal thickness was noted at the last follow-up with a mean thickness reduction of 70 µm (± 143) (p < 0.01). Conclusion In conclusion, none of the used parameter sets lead to tissue damage (when using a cautious titration) and, in summary, lead to an improvement in subretinal fluid and improvement in visual acuity. However, further prospective studies are needed to correctly identify the dependency of the treatment strategy on the outcome criteria.

Chronic Central Serous Chorioretinopathy

Central serous chorioretinopathy (CSCR) is a maculopathy characterized by the separation of the neurosensory layer as a result of fluid accumulation between the retinal pigment epithelium (RPE) and the photoreceptor layer. Classically it is classified as acute and chronic forms. When the disease lasts longer than 4-6 months, it is called a chronic form and comprises 15% of all CSCR cases. Although the exact etiology is unknown; studies emphasize changes in choroidal circulation causing choroidal ischemia and vascular hyperpermeability as well as subretinal fluid accumulation due to deterioration pump function of RPEs. Subretinal fluid accumulation can lead to photoreceptor dysfunction and loss of vision. Classical findings in patients are a decrease in visual acuity, blurred vision, metamorphopsia, micropsia, disturbance in color vision and dark adaptation, and scotomas. Diagnosis and follow-up depend on fundoscopy as well as imaging. Optical coherent tomography is the primary method. Fundus autofluorescence (FAF) is useful in defining RPE changes noninvasively. Fundus fluorescein angiography (FFA) shows the source of leakage. In recurrent, unresolved and chronic cases, OCT, FAF, FFA, and indocyanine green angiography can be used all together to manage the disease, to follow-up its extension, and to diagnose possible neovascular as well as polypoidal component. For the treatment of chronic CSCR patients, besides medical treatments such as carbonic anhydrase inhibitors, mineralocorticoid receptor, and glucocorticoid antagonists and intravitreal vascular endothelial growth factor antagonist (Anti-VEGF) injections, half-dose photodynamic therapy and subthreshold micropulse laser treatment are used. Prospective, controlled trials with large series for the treatment of chronic CSCR warranted.

Purpose. Subthreshold diode micropulse laser (SDM) treatment is believed to be safe method of treating clinical entities involving retinal edema. We present a case of serous edematous reaction of the retina to SDM treatment.Methods. Case report.Results. A patient with chronic central serous chorioretinopathy (CSCR) was treated with SDM Yellow multispot laser. Procedure had been preceded by careful titration of the laser power, which after achieving of the threshold parameter was decreased by 50%. The follow-up visit two days after treatment revealed significant central retinal edema and subretinal fluid. Fundus autofluorescence image showed thermal reaction from the RPE in the form of small spots of hyperfluorescence corresponding to the laser multispot pattern used for treatment. Retinal edema resolved after topical bromfenac and single intravitreal bevacizumab injection. Slight pigmentary reaction from the RPE persisted.Conclusion. In the treatment of CSCR, there is a need to significantly reduce threshold SDM power parameters or simply use very low power without titration.

Purpose. To investigate the risk factors for persistent or recurrent central serous chorioretinopathy (CSC). Materials and Methods. Consecutive treatment-naïve CSC patients were included from January 2017 to October 2018. All patients were asked to complete questionnaires, addressing previously described risk factors for the development of CSC. Patients were divided into two groups: those with acute CSC, who were in the first episode, with spontaneous resolution of subretinal fluid within 3 months, and with no recurrence within 1 year; and those with persistent or recurrent CSC, the remaining patients. Results. In total, 138 patients were enrolled: 20 (14.5%) with acute CSC and 118 (85.5%) with persistent or recurrent CSC. Using multivariate analysis, male sex (odds ratio (OR), 95% confidence interval: 5.63 [1.02–31.02]; p=0.047), older age (OR: 1.14 [1.03–1.25]; p=0.008), and higher Insomnia Severity Index score (OR: 1.30 [1.05–1.60]; p=0.015) were found to be independently associated with persistent or recurrent CSC. Conclusions. Male sex, age, and sleep disorders are risk factors for persistent or recurrent CSC in the natural history. These patients may require early photodynamic therapy. Treatment for sleep disorders is strongly recommended. All CSC patients may require careful and periodic follow-up.

Purpose. To evaluate anatomical retinal changes measured by spectral-domain optical coherence tomography (SD-OCT), after applying photodynamic therapy (PDT) for treatment of chronic central serous chorioretinopathy (CSC). Methods. A retrospective analysis was conducted on 43 patients (48 eyes) with chronic CSC treated with PDT. Visual acuity (VA), central retinal thickness (CRT), outer nuclear layer (ONL) thickness, subretinal fluid (SRF), and photoreceptor ellipsoid zone (EZ) measured by SD-OCT were collected at baseline and at 3, 6, and 12 months after PDT. Differences between normally distributed variables were calculated by a paired-sample t-test; p<0.05 was considered statistically significant. Results. Mean age was 50 ± 9.8 years. Mean time from diagnosis to PDT was 12.5 months. Baseline VA was 0.51 ± 0.24 and significantly improved (p<0.001) to 0.74 ± 0.26 one year after PDT. CRT and SRF significantly decreased (p<0.001) at 3, 6, and 12 months after treatment. ONL thickness and EZ did not significantly change at any point during follow-up. Conclusions. Not significant changes were found in the ONL or EZ 12 months after PDT.

Purpose To evaluate the short-term safety and efficacy of intravitreal bevacizumab for the treatment of intraretinal or subretinal fluid accumulation secondary to chronic central serous chorioretinopathy (CSC). Methods Twelve patients were treated with intravitreal injections of 2.5 mg bevacizumab at 6-to 8-week intervals until intraretinal or subretinal fluid resolved. Observation procedures were Early Treatment Diabetic Retinopathy Study best-corrected visual acuity (BCVA), ophthalmic examination, and optical coherence tomography (OCT), performed at 6- to 8-week intervals. Fluorescein angiography was performed at baseline visit and thereafter depending on clinical and OCT findings. Multivariate analysis of variance with repeated measures was used to calculate a statistical significance of change in BCVA and mean central retinal thickness, which were the main outcome measures. SAS statistical software was used for analyses. Results Patients received 2±1 intravitreal injections of bevacizumab on average during a follow-up of 24±14 weeks. Mean BCVA increased by 2±2 lines; the change in BCVA (log-MAR) was significant (p<0.02). Mean central retinal thickness decreased significantly over follow-up (p<0.05), with 6 patients (50%) showing complete resolution of subretinal fluid. Conclusions Anatomic and functional improvement following intravitreal bevacizumab injections suggest that vascular endothelial growth factor (VEGF) may be involved in fluid leakage in patients with chronic CSC. The results suggest a possible role for anti-VEGF agents in the treatment of chronic CSC. Further evaluation of intravitreal bevacizumab for chronic CSC in controlled randomized studies is warranted.

Purpose: To assess treatment with a 577-nm subthreshold micropulse laser (SML) in patients with chronic central serous chorioretinopathy (cCSC). Methods: This retrospective study included 38 patients treated with a 577-nm SML (Supra Scan; Quantel Medical) for cCSC. We included a subgroup of 18 patients with persistent subretinal fluid (SRF) after photodynamic therapy (PDT). Assessment included visual acuity (VA), central retinal thickness (CRT) and resolution of SRF. Results: At the last follow-up (mean 5 months), 74% of patients responded to therapy. The CRT decreased after treatment (mean CRT -115 µm, p < 0.001) and VA improved (mean logMAR -0.06, p = 0.039). No laser burns were detected with any imaging modality. In the subgroup of patients resistant to PDT, 61% of patients responded to therapy with a decrease in CRT (mean CRT -75 µm, p = 0.019). Conclusions: The 577-nm SML is an effective treatment for cCSC even in patients without sufficient improvement after PDT.

Abstract Background Central serous chorioretinopathy (CSC) is characterized by an accumulation of subretinal fluid (SRF) in the macula. It is usually treated by laser photocoagulation or photodynamic therapy (PDT) with consisting of different doses and power. This study aimed to compare the efficacy of half-dose PDT and one-third-dose PDT in chronic or recurrent CSC. Methods A retrospective review of patients with chronic or recurrent CSC who were treated with either a half-dose or one-third-dose PDT, and had follow up 12 months afterwards. Best-corrected visual acuity (BCVA), central retinal thickness (CRT) and resolution of subretinal fluid (SRF) at baseline as well as 1, 3, 6 and 12 months post-PDT were assessed. Results Forty-six eyes and 20 eyes received half-dose and one-third-dose PDT, respectively. The study showed efficacy of the one-third-dose PDT compared with half-dose PDT in BCVA improvement (0.10±0.04 logMAR for one-third-dose versus 0.17±0.04, for half-dose, P=0.148) and CRT improvement (125.6±24.6 μm for one-third-dose versus 139.1±16.54, for half-dose, P=0.933) at 12 months. The SRF recurrence rate was significantly higher in the one-third-dose PDT group compared with the half-dose PDT group (40.0% versus 15.2%, P=0.027) at 12-months. Conclusion At 12 months, the one-third-dose PDT was effective in terms of BCVA and CRT improvement, when compared with half-dose PDT. However, this study showed that one-third-dose PDT had a higher recurrence rate of SRF.

Purpose. To evaluate normalized short-wavelength fundus autofluorescence (SW-FAF) imaging changes over time as a predictive parameter for the retinal pigment epithelium (RPE) function in eyes compromised by acute central serous chorioretinopathy (CSCR) after indocyanine green angiography-guided verteporfin (Visudyne®, Novartis Pharma, Basel, Switzerland) photodynamic therapy (PDT) with a half-fluence rate (25 J/cm2). Methods. Quantitative data of SW-FAF grey values (SW-FAF GV) from a 350 μm (SW-350) and 1200 μm (SW-1200) diameter circle centered on the fovea and normalized with the level of SW-FAF GV in a 30° image of 20 eyes in 11 patients initially treated for unilateral acute symptomatic CSCR were collected and retrospectively analyzed after 7 years. A 2-sided t-test was calculated to explore the differences of SW-350 and SW-1200 between one month and the long-term follow-up. Results. Mean differences (95% CI) in SW-FAF GV between 1 month and 7 years after half-fluence PDT were 0.07 ± 0.11 for SW-350 ([95% CI: −0.002; 0.14], p=0.06) and 0.11 ± 0.15 for SW-1200 ([95% CI: 0.01; 0.21], p=0.03). Mean differences in SW-FAF GV of the contralateral untreated eye were 0.06 ± 0.14 for SW-350 ([95% CI: −0.04; 0.17], p=0.22) and 0.05 ± 0.13 for SW-1200 ([95% CI: −0.04; 0.15], p=0.22). Conclusion. After 7 years, normalized SW-FAF GV were significantly lower in eyes with resolved acute CSCR treated with reduced-fluence PDT compared to the follow-up after 1 month without correlation to explicit pattern changes or structural damages. Half-fluence PDT remains a safe and considerable treatment option in acute CSCR.

Lumbar disc herniation was treated by percutaneous discectomy using a new instrument for automatic aspiration and cutting of disc material. The inclusion criteria were limited to patients with pure disc herniation without stenosis or any other additional factors. Only contained hernias with a maximum size of 50% of the thecal sac were included. Three procedures out of 45 were technical failures. At 1-year follow-up 69% of the patients were satisfied. No complications were seen. The result was not influenced by the amount of disc material removed, age, duration of symptoms or the size of the disc hernia. Reduced size of disc hernia was found in 13 out of 14 satisfied patients followed by CT. All unsatisfied patients were conventionally operated on. The percutaneous treated patients had 1 day of hospitalisation and on average 11 weeks of sick-leave compared to an average of 6 days and 16 weeks following conventional discectomy.
