Clinical Trial Summary

In this pilot study the effect and safety of the use of steroid eye drops in chronic central serous chorioretinopathy (cCSC) will be evaluated. The study is conducted as a randomized single-blind placebo-controlled trial. Forty patients will be randomized to either steroid eye drops or placebo eye drops. Patients will self-administer the eye drops three times a day for four weeks.

Description:

Severe chronic central serous chorioretinopathy (cCSC) is a disease part of the pachychoroid disease spectrum and is characterized by the presence of subretinal and intraretinal fluid. Left untreated these patients are at serious risk of irreversible vision loss. The most effective treatment is photodynamic therapy (PDT), which is expensive, invasive and currently only available to a limited extent. Pachychoroid diseases are correlated to the use of systemic steroids or an increase in cortisol, to stress, sleep apnea and sildenafil use. In many cases there is no clear correlation to one of the risk factors. However, in clinical practice, a strikingly good effect on sub- and intraretinal fluid in another disease that is part of the pachychoroid disease spectrum was seen by using steroid eye drops (PPS; peripapillary pachychoroid disease). Steroid eye drops are used in many ophthalmic diseases, however, there is no clinical experience for the use steroid eye drops in cCSC.

The aim of this study is to assess the safety and the effect of steroid eye drops in patients suffering from cCSC for clinical, multimodal imaging, anatomical and functional outcomes. In addition, we want to gain insight in the mechanism of action and to investigate the effect of topical steroids on the intraocular pressure.

No previous studies have evaluated the effect of steroid eye drops on cCSC, therefore this study is set up as a pilot study, with a randomized, single-blinded, placebo controlled trial design. In total, forty patients will be randomized to either steroid eye drops or placebo eye drops. Patients will self-administer the eye drops three times a day for four weeks. The study will last for four weeks per patient and each patient will visit the outpatient clinic 2 times.

Treatment response will be objectified by multimodal imaging and by measuring the best-corrected visual acuity, after four weeks of using steroid eye drops or placebo.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: All patients will undergo multimodal imaging before inclusion and at the end point of the study, this includes invasive studies. All studies are part of the regular clinical work-up for cCSC and no additional (invasive) investigations will be performed. The use of steroid eye drops holds the risk of an increasement of intraocular pressure (IOP) and may induce cataract. However, both these risks are neglectable when used for 4 weeks only and outweighs the possible reductive effect of steroid eye drops on subretinal and intraretinal fluid.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in sub- and intraretinal fluid on OCT scan	The primary outcome measure of this study is the effect of steroid eye drops in cCSC on the amount of sub and intraretinal fluid. The difference in the amount of sub- and intraretinal fluid will be compared between the OCT scan made prior to the study and the OCT scan made at the second consultation after the study medication has been used for four weeks.	1 month after the start of treatment
Secondary	Change in best corrected visual acuity	Mean change in BCVA between baseline and after using the study medication for 4 weeks.	1 month after the start of treatment
Secondary	Intra ocular pressure (IOP)	Mean change in IOP between baseline and after using the study medication for 4 weeks.	1 month after the start of treatment
Secondary	Change of hyperfluorescent areas on fluorescence angiography (FA)	Mean change in hyperfluorescent areas on FA between baseline and after using the study medication for 4 weeks.	1 month after the start of treatment
Secondary	Change of hypercyanescent areas on Indocyanine Green Angiography (ICGA)	Mean change in hypercyanescent areas on ICGA between baseline and after using the study medication for 4 weeks.	1 month after the start of treatment
