About this study

Official title: To Determine Long-term Outcomes, Recurrence Rates, and Treatment Needs in Polypoidal Choroidal Vasculopathy(PCV)

To determine long-term outcomes, recurrence rates, and treatment needs in Polypoidal Choroidal Vasculopathy (PCV). Specifically, to describe the long-term outcomes, recurrence rates and treatment patterns PCV patients 5 years after first presentation. This study will also evaluate whether polyp closure within the first 12 months of therapy is associated with better long-term visual outcome and will also determine the risk of disease development in the fellow eye

Read the detailed description

The investigators will conduct a non-interventional, observational cohort study to assess the visual outcome of patients who have completed one of three recent randomized controlled trials in Polypoidal Choroidal Vasculopathy (PCV) EVERESTII, PLANET, PCV Treat and Extend (T\&E) study. After completion of the randomized controlled trails (2 years for EVEREST II and PLANET; 1 year for T\&E study), patients will be released from clinical trial protocol. At approximately 6 years (2019-2024), patients will be contacted by research coordinators and invited to attend a follow-up examination.

Study Design:

Non-interventional, observational, cohort study

Clinical coordinators will contact patients of:

  • EVEREST II (2013-2015)
  • PLANET (2014-2015)
  • PCV T\&E (2018-2019) at ~72 +/- 6 months after their initial baseline visits (2019-2024) Study Visits and Procedures Participants will only be expected to attend 1 evaluation clinic which will last approximately 3 hours

Contact of prior trial participants Participants from prior randomized control trials (EVEREST II, PLANET and PCV T\&E) will be contacted by phone and invited to attend 1 post-trial evaluation clinic.

Historical Information A history will be elicited from the participant and extracted from available medical records.

Data to be collected will include: age, gender, ethnicity and race, past medical history and medications being used, as well as ocular diseases, surgeries, and treatment.

An assessment of visual related quality of life will be performed using the impact of visual impairment (IVI) questionnaire.

Testing Procedures The following procedures will be performed (using the study technique and by delegated personnel) as part of usual care, it does not need to be repeated specifically for the study if it was performed within the defined time (within 14 days prior to visit).

  1. Best-corrected Visual Acuity (BCVA) will be measured using the ETDRS VA protocol following manifest refraction.
  2. Optical Coherence Tomography/ OCT Angiography: OCT and OCTA will be performed. Both standard and enhanced depth imaging scans will be performed.
  3. Ocular examination on each eye including slit lamp, measurement of intra-ocular pressure, lens assessment, and dilated ophthalmoscopy.
  4. Fundus Photography
  5. Fundus fluorescein and Indocyanine Green angiography: FFA and ICGA will be performed.

Disease characteristics of the study eye assessed by the investigator including:

  • Activity of PCV based on ICGA.
  • Presence of activity clinically as evidence by presence of hemorrhage, edema.
  • Presence of activity as evidence by intra retinal or sub retinal fluid on OCT. The clinical data from the exit of trial to this visit will be accessed from medical records both paper- based and electronic formats.

All the data collected from this visit, data from the prior trial and the clinical course and treatment from the end of the trial to this visit will be anonymized and sent to the Singapore Eye Research Institution (SERI) for analysis. Only the principal investigator and study team at site and SERI will have access to the anonymized collected information.

Questions about this trial

What is this clinical trial studying?

An observational study of Polypoidal Choroidal Vasculopathy, run by Singapore National Eye Centre at 3 sites in Singapore.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Long term prognostication (time frame: within 72 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2025; AzTrials last refreshed its copy on 6 Nov 2026.
