Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients with central serous chorioretinopathy (CSC) will be monitored with laser speckle flow graphy (LSFG), swept source optical coherence tomography (SS-OCT) and SS-OCT angiography (SS-OCTA). The aim is to unveil the flow and pulse wave characteristics of the choroidal circulation in acute CSC and chronic CSC.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Acute CSC - The proposed study tests the hypothesis that choroidal blood flow characteristics are related to the eventual resolution of subretinal fluid. Such relation can shed light on pathophysiological disease mechanisms and constitute a biomarker for disease activity.

Chronic CSC - The proposed study tests the hypothesis that choroidal blood flow characteristics will change in response to standard treatment with PDT. The research of such changes will increase the understanding of the treatment response. This knowledge will help in the effort to understand the why some patients are non-responsive to the treatment.

Acute

Patients with acute first attack CSC with subretinal fluid (SRF) on OCT and symptom duration under 4 months.

No interventions assigned to this group

Chronic

Patients with chronic CSC, i.e. symptoms and SRF for more than 4 months.

Verteporfin

Intervention Type DRUG

Chronic CSC are receiving one treatment before the observation period.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Able to sign informed consent
* Possible to obtain fundus imaging
* Acute CSC ˂4 months of duration in one eye, defined as:

1. Subfoveal presence of SRF on OCT
2. Present attack is 1st -3rd attack of CSC

b) Patient history and examination consistent with acute CSC c) Characteristic appearance of acute CSC on fundus autofluorescence (FAF) and OCT
* Chronic CSC ≥4 months of duration in one eye, defined as:

1. Subfoveal presence of SRF on OCT
2. Subjective visual loss/symptoms
3. Characteristic appearance of chronic CSC on FAF, fluorescein angiography (FA), and indocyanin angiography (ICGA) and OCT
4. Patient history and examination consistent with chronic CSC

Exclusion Criteria

* History of retinal disease other than CSC (e.g. retinal detachment)
* Contraindications for FA, ICGA or PDT (only for chronic CSC)
