Photodynamic therapy in chronic central serous chorioretinopathy with subretinal fluid outside the fovea

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. 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. In 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. Half-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 symptom

Clinical characteristics of chronic central serous chorioretinopathy patients with insufficient response to reduced-settings photodynamic therapy

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. Data on age, sex, best-corrected visual acuity (BCVA), PDT spot size, characteristics on fluorescein angiography (FA), indocyanine green angiography (ICGA), and optical coherence tomography (OCT) were obtained. Results: Twenty-six patients in the successful PDT group (20 males, 6 females) had a mean age of 51 years (range, 25–78). In the unsuccessful PDT group, 20 males with a mean age of 60 years (range, 34–78) were included. At last visit before PDT, age, percentage of males, and percentage of patients with diffuse leakage > 1 optic disc diameter on FA were higher in the unsuccessful PDT group (p = 0.010, p = 0.029, and p = 0.008, respectively). At last visit before PDT, BCVA and the percentage of patients with intense hyperfluorescence on ICGA were lower in the unsuccessful group (p = 0.017 and p = 0.004, respectively). Patients with intense hyperfluorescence on ICGA were more likely (95% CI 1.3–333 times) to have a successful outcome (p = 0.045). A decrease in SFCT at final visit was observed in both groups (− 111 μm and p = 0.013, and − 141 μm and p = 0.007, respectively). BCVA only improved at final visit in the successful PDT group (5 Early Treatment of Diabetic Retinopathy Study letters, p < 0.001). Conclusions: Chronic CSC patients with recurrent or persistent SRF after PDT are characterized by a higher percentage of males, more patients with diffuse leakage on FA, more patients without intense hyperfluorescence on ICGA, higher age, and lower pre-PDT and long-term BCVA than in the successful PDT group. A reduction in SFCT after PDT does not necessarily lead to complete resolution of SRF, while a resolution of SRF appears to be required to lead to a significant BCVA improvement in cCSC

The spectrum of polypoidal choroidal vasculopathy in Caucasians: clinical characteristics and proposal of a classification

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. Results: This study involved 74 eyes of 66 patients with PCV, with a mean age at onset of 73 years and a female preponderance of 66%. The mean number of polypoidal lesions per eye was 1 (range: 1–5 lesions), out of which 75% was located in the macula and 19% in the peripapillary region. Of the 74 eyes, 37 eyes (50%) had PCV associated with a drusenoidal neovascular age-related macular degeneration (AMD) phenotype (PCV-AMD) and 18 eyes (24%) had PCV associated with non-polypoidal type 1 choroidal neovascularization/branching vascular network (PCV-BVN) without signs of drusenoidal AMD, while 19 eyes (26%) had idiopathic, isolated PCV (iPCV). The mean subfoveal choroidal thickness measured in 22 patients was 245 μm (range: 71–420 μm). In 51% of patients, the initially performed therapy showed good anatomical recovery (resolution of intra- and subretinal fluid). Conclusions: A spectrum of PCV (aneurysmal type 1/sub-RPE neovascularization) can be seen in Caucasian patients. PCV associated with a drusenoidal neovascular AMD phenotype in Caucasians is phenotypically and presumably pathophysiologically more associated with neovascular AMD (PCV-AMD: type A PCV). However, this may not be the case for patients with PCV with non-polypoidal type 1 choroidal neovascularization or BVN and no signs of drusenoidal AMD (PCV-BVN: type B PCV), and for patients with idiopathic PCV without associated drusen or BVN (iPCV; type C PCV). Most patients have a thin choroid, even when drusen are absent. For the entire patient group, a moderate anatomical recovery was observed after treatment

Maladaptive personality traits, psychological morbidity and coping strategies in chronic central serous chorioretinopathy

Purpose: ‘Type A’ behavioural characteristics and psychosocial stress have traditionally been associated with chronic central serous chorioretinopathy (cCSC). However, a characteristical personality profile could not be identified in these patients and the presumed association with stress is subject to controversy, due to a lack of convincing studies using validated measuring instruments. In this study, we aimed to assess maladaptive personality traits, psychological morbidity and coping strategies in patients with cCSC, in order to identify potentially modifiable psychosocial aspects which could be used in support to current standard treatment. Methods: A cross-sectional study in a cohort of 86 patients with cCSC using validated questionnaires. Findings were compared to both Dutch population reference data and reference data from patients treated for Cushing's disease. Results: Maladaptive personality traits were not more prevalent in patients with cCSC than in the general population, and psychological morbidity was not increased. Patients with cCSC were shown to make more use of passive coping, active coping and seeking social support. Interestingly, personality, psychological morbidity and coping characteristics of patients with cCSC were more comparable to features of patients treated for Cushing's disease than to population-based data. Conclusion: Maladaptive personality traits such as type A behavioural characteristics are not more prevalent in patients with cCSC. Patients with cCSC make more use of certain coping strategies, which could be addressed by psychosocial care to improve self-management. Further research is needed establish whether the course of disease can be improved by altering coping and reducing ‘stress’

Half-Dose Photodynamic Therapy Versus Eplerenone in Chronic Central Serous Chorioretinopathy (SPECTRA): A Randomized Controlled Trial

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. Eligible patients were randomized at a 1:1 ratio to receive either indocyanine green angiography-guided half-dose PDT or oral eplerenone for 12 weeks. Both anatomical and functional outcomes were evaluated at 3 months after the start of treatment. Results: A total of 107 patients were randomly assigned to receive either half-dose PDT (n = 53) or eplerenone treatment (n = 54). Thirteen patients (3 in the PDT group and 10 in the eplerenone group) did not adhere to the study protocol. At the 3-month evaluation visit, 78% of patients in the PDT group had complete resolution of subretinal fluid accumulation compared to only 17% of patients in the eplerenone group (P < .001). Mean best-corrected visual acuity in Early Treatment of Diabetic Retinopathy Study letters at the 3-month evaluation visit was 83.7 ± 10.8 and 82.8 ± 9.0 in the PDT and eplerenone groups, respectively (P = .555). In addition, mean retinal sensitivity on microperimetry was 25.4 ± 3.4 dB and 23.9 ± 4.0 dB in the PDT and eplerenone groups, respectively (P = .041). Finally, mean vision-related quality of life scores were 87.2 ± 8.5 and 83.8 ± 12.1 in the PDT and eplerenone groups, respectively (P = .094). Three patients (6%) in the PDT group experienced adverse events during the study compared to 18 patients (33%) in the eplerenone group. Conclusions: Half-dose PDT is superior to oral eplerenone for cCSC with respect to both short-term safety and efficacy outcomes

Neovascular age-related macular degeneration without drusen in the fellow eye: clinical spectrum and therapeutic outcome

Purpose: To investigate the clinical characteristics and therapeutic outcome of patients with neovascular age-related macular degeneration (nAMD) in 1 eye, without drusen in the fellow eye. Patients and methods: Medical records of 381 patients were analyzed to identify the cases. The main outcomes included Early Treatment Diabetic Retinopathy Study (ETDRS) best-corrected visual acuity (BCVA) and change in central retinal thickness (CRT). These parameters were reviewed at baseline, first follow-up visit, and after 6, 12, and 24 months. Results: Out of 381 patients, 29 cases (8%) were included (of whom 3 had polypoidal choroidal vasculopathy [PCV]) who were treated with anti-vascular endothelial growth factor (anti-VEGF) therapy which was supplemented by photodynamic therapy (PDT) in the PCV patients. Overall, no statistically significant change in mean BCVA was observed during follow-up. BCVA improved or remained stable (defined as a gain in BCVA, a stable BCVA, or a loss of = 5 ETDRS letters at final follow-up. A gain of >= 15 ETDRS letters at final follow-up was seen in 5 patients (17%). Mean CRT had decreased significantly with 99 mu m (P < 0.001) at 24 months after the initial visit. Conclusion: There is a clinical spectrum of nAMD that is not associated with drusen in the fellow eye. Patients with nAMD without drusen in the fellow eye respond to anti-VEGF treatment and, in cases of PCV, to supplemental PDT. The pathophysiology of this spectrum of nAMD may be different from drusen-associated age-related macular degeneration
