NCT05278169

Brief Summary

Objectives:

  1. 1.To conduct a Natural History Observation Study to characterize the clinical features and progression of Central Serous Chorioretinopathy (CSCR) from the earliest to the vision-threatening stages.
  2. 2.Collect genetic samples of affected individuals and their families to establish whether there is a genetic basis for the disease.
  3. 3.To create a Registry of patients affected by CSCR who may agree to be contacted for inclusion in future clinical trials.
  4. 4.To determine the incidence and risk factors for progression of pachychoroid phenotypes identified from the unaffected fellow eyes of CSCR patients.

Outcome Measures

Primary Outcomes (3)

  • Longitudinal change of retinal pigment epithelium defects on Fundus Autofluorescence (FAF) from baseline and between visits.

    Fundus Autofluorescence - performed using Spectralis (Heidelberg Engineering, Heidelberg, Germany) to acquire 35 degree and 55 degree image centred on the fovea.

    At baseline (Month 0), Month 6, Month 12, Month 18 and Month 24.

  • Longitudinal change of retinal pigment epithelium defects on Spectral Domain Optical Coherence Tomography (SD-OCT) from baseline and between visits.

    Macular Spectral Domain Optical Coherence Tomography (SD-OCT) - performed using Spectralis (Heidelberg Engineering, Heidelberg, Germany) to acquire a 6x6 mm cube comprising of 97 retinal scans centred on the fovea.

    At baseline (Month 0), Month 6, Month 12, Month 18 and Month 24.

  • Longitudinal change of retinal pigment epithelium defects on infrared imaging from baseline and between visits.

    Ultra-widefield color fundus photography and autofluorescence (Optos PLC, Dunfermline, UK) - performed to capture 240 degree image centred on the fovea.

    At baseline (Month 0), Month 6, Month 12, Month 18 and Month 24.

Secondary Outcomes (43)

  • Progressive attenuation of outer nuclear layer (ONL), external limiting membrane (ELM) and ellipsoid zone (EZ) on SD-OCT.

    At baseline (Month 0), Month 6, Month 12, Month 18 and Month 24.

  • Changes of subfoveal choroidal thickness on swept source optical coherence tomography (SS-OCT).

    At baseline (Month 0), Month 6, Month 12, Month 18 and Month 24.

  • Incidence of intraretinal cysts.

    At baseline (Month 0), Month 6, Month 12, Month 18 and Month 24.

    At baseline (Month 0), Month 6, Month 12, Month 18 and Month 24.

  • +38 more secondary outcomes

Sampling MethodNon-Probability Sample
Study Population

The study aims to enrol a total of 350 patients with CSCR, of which: * 170 subjects from a previous cross-sectional observation study titled 'The Association of Sleep Disturbances and Maculopathy' (IRB / REC No.: 2018.158) at the CUHK Eye Centre. * An addition of 180 subjects will be recruited during the proposed study duration. Of the 180 new recruits, 100 will be recruited from Hong Kong Eye Hospital and CUHK Eye Centre.The remaining 80 subjects will be recruited from Department of Ophthalmology and Visual Sciences, Prince of Wales Hospital and Alice Ho Miu Ling Nethersole Hospital.

You may qualify if:

  • Presence or evidence of prior serous retinal detachment documented on OCT involving the posterior pole unrelated to another disease process.
  • At least 1 area of retinal pigment epithelium (RPE) alteration on FAF, SD-OCT, or infrared imaging.
  • Subfoveal choroidal thickness (SFCT) of 300μm or more on SD enhanced depth imaging (EDI) OCT or SS-OCT for at least one eye.
  • Patient 18 years or older.
  • Willing to undergo pupil dilation, and protocol-required procedures for both eyes.

You may not qualify if:

  • Other maculopathy on clinical examination such as age-related macular degeneration (AMD).
  • Media opacity such as cataract that could interfere with adequate acquisition of fundal images.
  • Pregnant or nursing women.
