Purpose: Comparing the effect of half-dose photodynamic therapy and high-density subthreshold micropulse laser treatment on retinal pigment epithelial detachments (PEDs) in chronic central serous chorioretinopathy.
Methods: This study included data from the PLACE trial, a prospective randomized controlled trial comparing half-dose photodynamic therapy and high-density subthreshold micropulse laser treatment in chronic central serous chorioretinopathy. Main outcome measurements were changes in both the foveal PED and the highest PED within the macula at baseline compared with first and final evaluation visit.
Article Synopsis
- RVCL-S is a genetic small vessel disease linked to TREX1 mutations, affecting the retina and brain, with optical coherence tomography (OCT) being used to assess retinal layer thickness as a biomarker.
- A study comparing 17 TREX1 mutation carriers to 9 controls found significantly reduced thickness in the peripapillary retinal nerve fiber layer (pRNFL) and total macular volume (TMV) among mutation carriers.
- Results suggest that OCT findings indicate retinal thinning in RVCL-S patients, even in cases with normal eye examinations, highlighting the potential for using OCT as an early diagnostic tool for vascular retinopathies.
Purpose: To compare the efficacy and safety between half-dose photodynamic therapy (PDT) and eplerenone therapy for treating chronic central serous chorioretinopathy (cCSC).
Design: This was a multicenter, open-label, randomized controlled trial.
Methods: This investigator-initiated trial was conducted in 3 academic medical centers in the Netherlands.
Purpose: To describe the treatment outcomes and recurrence risk of chronic central serous chorioretinopathy (cCSC) in patients who had complete resolution of subretinal fluid (SRF) after either primary half-dose photodynamic therapy (PDT) or high-density subthreshold micropulse laser (HSML) in the PLACE trial.
Methods: This multicentre prospective follow-up study evaluated cCSC patients at 1 year after completion of the PLACE trial. Outcomes included: complete resolution of SRF on OCT, best-corrected visual acuity (BCVA) in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters, retinal sensitivity on microperimetry and a visual function questionnaire (NEI-VFQ25).

Graefes Arch Clin Exp Ophthalmol
February 2021
Purpose: To describe the clinical characteristics and outcome of polypoidal choroidal vasculopathy (PCV), also known as aneurysmal type 1 (sub-retinal pigment epithelium (RPE)) neovascularization, in Caucasian patients.
Methods: Single-centre study in 66 Caucasian patients with a diagnosis of PCV based on optical coherence tomography scan and indocyanine green angiography. Clinical characteristics and multimodal imaging were collected and assessed by an experienced retina specialist.
Purpose: To generate conclusive evidence regarding the noninferiority of intravitreal bevacizumab compared with ranibizumab in patients with diabetic macular edema (DME).
Design: Comparative, randomized, double-masked, multicenter, noninferiority clinical trial.
Participants: Eligible patients were older than 18 years, diagnosed with type 1 or type 2 diabetes mellitus, with glycosylated hemoglobin of less than 12%, central area thickness of more than 325 μm, and visual impairment from DME with a best-corrected visual acuity (BCVA) between 24 letters and 78 letters.
Purpose: To assess whether chronic central serous chorioretinopathy (cCSC) patients without a complete resolution of subretinal fluid (SRF) after either half-dose photodynamic therapy (PDT) or high-density subthreshold micropulse laser (HSML) treatment may benefit from crossover treatment.
Design: Multicenter prospective interventional case series.
Methods: cCSC patients with persistent SRF at the final visit of the PLACE trial were included.
Purpose: Comparing the efficacy of intravitreal injections of bevacizumab to ranibizumab in the treatment of macular edema (ME) resulting from retinal vein occlusion (RVO).
Design: Comparative, randomized, double-masked, multicenter, noninferiority clinical trial. The noninferiority margin was 4 letters.
Purpose: Central serous chorioretinopathy (CSC), a distinct form of macular degeneration, has been associated with glucocorticoid use and possibly also with an increased endogenous activity of the hypothalamic-pituitary-adrenal (HPA) axis. To estimate long-term glucocorticoid exposure, measurement of hair cortisol concentrations (HCC) has emerged. This cross-sectional study aimed to investigate HCC, as a reflection of chronic endogenous steroid exposure, in a cohort of patients with chronic CSC (cCSC).

Patients And Methods: A total of 66 patients (81 eyes) with active severe cCSC were studied, and their response to PDT was compared with a control group consisting of 35 active cCSCs (37 eyes) that did not display characteristics of severity. Best-corrected visual acuity (BCVA) and complete resolution of subretinal fluid (SRF) were considered as main outcome measures.
Article Synopsis
- The study explored the relationship between personality traits, psychological stress, and coping strategies in patients with chronic central serous chorioretinopathy (cCSC), challenging previous assumptions linking Type A behavior and stress to the condition.
- Findings indicated that maladaptive personality traits were not more common in cCSC patients compared to the general population, and that psychological morbidity levels were similar as well.
- The study highlighted that cCSC patients utilized various coping strategies, particularly passive and active coping, and suggested that focusing on these strategies through psychosocial care could enhance self-management and potentially improve treatment outcomes.
Purpose: To assess parameters on optical coherence tomography (OCT), and their correlation with best-corrected visual acuity (BCVA) in patients with non-resolving central serous chorioretinopathy (CSC).
Methods: For 25 non-resolving CSC patients treated with photodynamic therapy (PDT), the thickness of retinal layers was assessed on the foveal spectral-domain (SD) OCT scan. Evaluated OCT parameters included the central retinal thickness (CRT), defined as the internal limiting membrane (ILM) to ellipsoid zone (EZ) distance, and the second band thickness (SBT), defined as the EZ to hyperreflective subretinal accumulation distance.
Purpose: To compare the anatomic and functional efficacy and safety of half-dose photodynamic therapy (PDT) versus high-density subthreshold micropulse laser (HSML) treatment in patients with chronic central serous chorioretinopathy (cCSC).
Design: Open-label, multicenter, randomized controlled clinical trial.
Participants: Patients with cCSC whose disease had to be confirmed by both clinical characteristics and findings on multimodal imaging.
Purpose: To identify characteristics of Caucasian chronic central serous chorioretinopathy (cCSC) patients without a complete resolution of subretinal fluid (SRF) after reduced-settings photodynamic therapy (PDT), or with a recurrence of SRF after PDT.
Methods: Chronic CSC patients treated with reduced-settings PDT were divided into a successful PDT group and unsuccessful PDT group. Patients in the successful PDT group did not have any subretinal fluid (SRF) during follow-up after PDT, whereas the unsuccessful PDT group was categorized based on either persistence or recurrence of SRF after PDT treatment.
Objective: Central serous chorioretinopathy (CSC), a specific form of macular degeneration, has been reported as presenting manifestation of Cushing's syndrome. Furthermore, CSC has been associated with both exogenous hypercortisolism and endogenous Cushing's syndrome. It is important to know whether CSC patients should be screened for Cushing's syndrome.

Methods: In 103 subjects from 23 families with at least 2 affected patients with CSC per family, prospective extensive ophthalmologic examination was performed, including best-corrected visual acuity, indirect ophthalmoscopy, digital color fundus photography, optical coherence tomography, fundus autofluorescence, and fluorescein angiography imaging. From these, 24 individuals from 6 families had undergone extensive ophthalmologic examination in either 1994 or 1995 and were followed up in this study.
Photodynamic therapy in chronic central serous chorioretinopathy with subretinal fluid outside the fovea.
Graefes Arch Clin Exp Ophthalmol
October 2017
Purpose: To 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.
Methods: In 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.
Article Synopsis
- The study focused on patients with neovascular age-related macular degeneration (nAMD) in one eye but without drusen in the other eye, analyzing clinical features and treatment outcomes.
- A total of 381 patient records were examined, revealing that 8% (29 patients) had this specific condition and received anti-VEGF therapy, with some also getting photodynamic therapy (PDT).
- While there was no significant overall change in best-corrected visual acuity (BCVA) during follow-ups, a majority of patients showed stable or improved vision, and central retinal thickness significantly decreased, indicating a positive response to treatment despite the absence of drusen.
Purpose: To assess the short-term outcome of and possible temporary vision loss after half-dose verteporfin photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (cCSC).
Methods: In this prospective study, 14 eyes of 13 cCSC patients who underwent half-dose PDT were included. Patients received spectral-domain optical coherence tomography (OCT) imaging and microperimetry before PDT on the day of treatment and 1 week after treatment.
Article Synopsis
- Cerebroretinal vasculopathy and related disorders are now recognized as a single disease linked to mutations in a specific gene, specifically termed ‘retinal vasculopathy with cerebral leukodystrophy’.
- In a study of 78 individuals from 11 families, researchers identified five different mutations and gathered extensive data, revealing that 64 mutation carriers exhibited vascular retinopathy and notable neuroimaging findings, such as white matter lesions.
- Clinical symptoms included a range of neurological issues, with a mean diagnosis age of 42.9 years and an average death age of 53.1 years, alongside systemic problems like liver disease and hypertension in many patients.
Purpose: To compare the effectiveness of bevacizumab and ranibizumab in the treatment of exudative age-related macular degeneration (AMD).
Design: Multicentre, randomized, controlled, double-masked clinical trial in 327 patients. The non-inferiority margin was 4 letters.
