Title: Prospective Study on the Efficacy of 1.5mg Bevacizumab Versus Selective Subthreshold Micropulslaser in Central Serous Chorioretinopathy
Brief Summary: The purpose of this study is to evaluate the clinical efficacy of an initial subthreshold retinal micropulselasercoagulation versus a single intravitreal 1.5mg bevacizumab injection in central serous choriretinopathy, as the micropulse will selectively treat the damaged RPE to induce reproliferation of healthy RPE cells, whereas the intravitreal injection should non-selectively stop the RPE leakage.


Options:
A: Inclusion Criteria:

1. best-corrected visual acuity (BCVA) between 0.0 and 1.0 logarithm of the minimal angle of resolution (logMAR)
2. presence of subfoveal fluid persisting for 3 months or more on optical coherence tomography (OCT)
3. presence of leakage and multifocal/diffuse RPE decompensation on fluorescein angiography (FA)
4. choroidal vascular hyperpermeability and abnormal dilation of choroidal vasculature on indocyanine angiography (ICGA)

Exclusion Criteria:

1. previous treatment, such as laser photocoagulation, PDT, intravitreal injection of steroid or anti-VEGF agent
2. evidence of choroidal neovascularization
3. any other ocular diseases that could affect visual acuity
4. systemic steroid treatment in the previous 12 months
5. media opacity such as cataract that could interfere with adequate acquisition of OCT, FA and ICGA images
B: Inclusion Criteria:

* Anamnestic reduction of visual acuity
* Atients with best-corrected visual acuity (BCVA) of 20/200 or better
* Presence of subretinal fluid (SRF) on optical coherence tomography (OCT)
* Presence of active angiographic (multi)focal leakage in fluorescein angiography (FA) caused by ICSC but not choroidal neovascularisation (CNV) or other diseases
* Absence of other retinal or ocular diseases (e. g. glaucoma, vessel diseases, vein occlusion or proliferative retinopathy)
* Absence of cataract or media opacities of a degree which precludes taking retinal photographs and FA's
* Absence of angle closure glaucoma which precludes pharmacological dilatation of the pupil.

Exclusion Criteria:

* Patients who received any previous treatment, including PDT or focal cw laser photocoagulation for ICSC, or who had evidence of CNV, PCV, or other maculopathy on clinical examination or FA were excluded.
* Patients receiving exogenous corticosteroid treatment, with systemic diseases such as Cushing's disease or renal diseases, and pregnant patients also were excluded.
* Informed consent was obtained from all subjects, and the study protocol was approved by the ethics committee of the University of Kiel.
C: INCLUSION CRITERIA:

* male and female patients ≥ 18 years of age who are able to give written informed consent
* active chronic central serous chorioretinopathy
* subjective visual loss \> 6 weeks, interpreted as onset of active disease
* subretinal fluid that includes the fovea on OCT scanning at Baseline Examination.

Please NOTE: Subretinal fluid does not have to include fovea on OCT to be eligible for treatment at Control Visit 1, as long as there is persistent subretinal fluid in the macula, which is interpreted as persistently active disease (see 5.7 "Retreatment criteria and considerations").

* hyperfluorescent areas on ICG angiography
* ≥1 ill-defined hyperfluorescent leakage areas on fluorescein angiography with retinal pigment epithelial window defect(s) that are compatible with chronic CSC

EXCLUSION CRITERIA:

The participant may not enter the study if ANY of the following apply:

* any previous treatments for active CSC in the study eye
* current treatment with corticosteroids (topical or systemic), or anticipated start of corticosteroid treatment within the first 7-8 months from the start of the trial period
* evidence of other diagnosis that can explain serous subretinal fluid or visual loss
* BCVA \< 20/200 (Snellen equivalent)
* profound chorioretinal atrophy in central macular area on ophthalmoscopy and OCT
* myopia \> 6 dioptres
* visual loss and/or serous detachment on OCT \< 6 weeks
* continuous and/or progressive visual loss \> 18 months or serous detachment on OCT \> 18 months
* no hyperfluorescence on ICG angiography
* intraretinal edema on OCT
* (relative) contraindications for PDT treatment (pregnancy, porphyria, severely disturbed liver function). Pregnancy will not be routinely tested in female patients, but the possibility of pregnancy will be discussed during eligibility screening
* (relative) contraindications for fluorescein angiography or ICG angiography (known allergies especially against shellfish, previous reactions)
* Soft drusen in treated eye or fellow eye, signs of choroidal neovascularization on ophthalmoscopy and/or fluorescein angiography/indocyanine green angiography
D: Inclusion criteria:

* CSC of \>4 months duration

Exclusion Criteria:

* History of macular or chorioretinal inflammation
* Lens / corneal opacities

Answer: D
