Trial summary

Many patients will have underlying maculopathy present when undergoing cataract surgery, which are not visible on fundoscopy alone. Knowledge of this underlying pathology will allow an improved consenting process and discussion with the patient regarding the risks, visual prognosis and recovery following cataract… Read more about this study

Study population: This was a prospective cross-sectional study of 626 consecutive patients attending cataract assessment clinics at the Sussex Eye Hospital between 2/11/20 and 6/11/20. ]As part of work to decrease waiting times for patients in the wake of the first wave of COVID-19 pandemic and the shutdown of non-emergency services, a week of activity dedicated to cataract assessment was undertaken at Brighton \& Sussex University Hospitals NHS trust between 2nd and 6th November 2020.

Who may be able to join

  • Patients referred for cataract surgery

Who cannot join

  • Patients unable to attend the cataract assessment clinic
  • Morbid patients who cannot be assessed on OCT or slit lamp

About this study

Official title: Importance of Ocular Coherence Tomography During Cataract Assessment

Many patients will have underlying maculopathy present when undergoing cataract surgery, which are not visible on fundoscopy alone. Knowledge of this underlying pathology will allow an improved consenting process and discussion with the patient regarding the risks, visual prognosis and recovery following cataract surgery. Incidental findings in the fellow eye would also allow for improved diagnosis and management of these patients without adding significant additional time to specialist high volume cataract assessment clinics.

Read the detailed description

The majority of anterior segment pathology may be diagnosed with simple slit lamp biomicroscopy, but posterior segment pathology may not be quite so obvious and can be missed on simple examination especially if a visually significant cataract is present impeding the view. There is also a degree of subjectivity from how much the cataract impairs the vision in comparison to the other elements of the optical pathway within the eye, and whilst there is no single way to evaluate this.

Optical coherence tomography (OCT) has been widely present in ophthalmology clinics since it's development 20 years ago although it is not commonly used in all units for the pre-operative assessment of patients referred for cataract surgery in high volume set ups such as the National Health Service (NHS) in the United Kingdom. There may still be reluctance to use OCT in a normal cataract assessment clinic as it may be perceived as an additional step that decreases time efficiency and increase financial investment in the services.

In this study we sought to investigate the prevalence of retinal pathology in the patient cohort, the comparison of subjective clinical slit lamp fundoscopy assessmenet with OCT findings and the co-incidental OCT findings in the fellow eye at the time of cataract assessment. OCT was chosen as the most efficient way to support clinicians in the assessment clinics, and to see if the addition of this step added value to the patient consultation and pre-operative assessment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ocular Coherence TomographyDiagnostic test

    Also called Swept Source ocular coherence tomography

    OCT images were recorded as a fast macular radial line scan with captured on either Heidelberg Spectralis (Heidelberg Engineering GmbH, Germany) or Topcon DRI Triton (Topcon Medical Systems inc. USA).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of occult macular pathologies in the eye referred for cataract surgery

    Comparison of slitlamp biomicroscopy fundus finding with ocular coherence tomography (OCT) scan of the macula

    Measured: During the cataract assessment clinic

Secondary outcomes (1)
  1. Incidence of macular pathologies in the fellow eye

    Noting the incidence of macular pathologies noted on OCT

    Measured: During the cataract assessment clinic

Questions about this trial

What is this clinical trial studying?

An observational study of Cataract Senile and Macula Hole, run by Brighton and Sussex University Hospitals NHS Trust at 1 site in United Kingdom.

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 1 inclusion and 2 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 3 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. 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?

Incidence of occult macular pathologies in the eye referred for cataract surgery (time frame: During the cataract assessment clinic). 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 3 Nov 2023.
