Incidence of Macular Edema in a Uveitis Population

November 12, 2024 updated by: Lasse Jørgensen Cehofski, Aalborg University Hospital

Incidence of Macular Edema in a Uveitis Population of 1500 Patients

Macular edema from uveitis is a serious condition that can lead to vision loss. Uveitis is an inflammation inside the eye, and macular edema is when fluid builds up in the central part of the retina, called the macula, which is crucial for clear vision. This fluid buildup can blur vision, sometimes severely. Managing this condition can be challenging and may require several treatments to reduce the fluid and protect sight. While we know macular edema is a common cause of vision loss in uveitis, there's limited data on how often it affects people in Europe

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The study population will consist of all uveitis patients treated at hospitals in the North Denmark Region.The included study population consists of all patients with a primary or secondary first-time discharge diagnosis of uveitis from the ophthalmologic department at Aalborg University Hospital in the North Denmark Region. Both inpatient and outpatient diagnoses are included. The following ICD-10 codes for uveitis will be included: DH200 acute and subacute anterior uveitis, DH201 Chronic anterior uveitis, DH209 anterior uveitis unspecified, DH208 other anterior uveitis, DH300 focal posterior uveitis, DH309 posterior uveitis unspecified, DH308 other posterior uveitis, DH301 disseminated posterior uveitis, DH302 intermediate uveitis, and DH441E panuveitis

Description

Inclusion Criteria:

  • Hospital-admitted patients in the North Denmark Region with non-infectious uveitis.
  • Both juvenile and adult patients.
  • Diagnosed with non-infectious uveitis by a medical doctor.
  • Patients presenting with unspecific macular edema may be included if medical records indicate uveitis as the cause of the edema.

Exclusion Criteria:

  • Patients incorrectly classified as having uveitis based on their medical records (no confirmed diagnosis of uveitis).
  • Patients with infectious uveitis.
  • Macular edema due to other cause than uveitis will not count as uveitis associated edema

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Non-infectious uveitis patients treated at a hospitals in the North Denmark Region
Drug: Local and systemical treatment
Evaluating the management of the edema including topical/local treatment (dexamethasone and NSAID, periocular injections, and dexamethasone intravitreal implant) and systemic treatment (prednisolone, DMARD, and biological agents, for example TNF-alpha inhibitors and interleukin-6 inhibitors). Moreover, the duration of any treatment as well as numbers of injections or implants.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of Macular Edema in patients with Uveitis
Time Frame: 10 years
The outcome of interest is macular edema in non-infectious uveitis. We will estimate the incidence rate and cumulative incidence of macular edema in patients with uveitis. In addition, the population will be stratified according to sex, age, non-infectious uveitis subtype, HLA- subtype, and ethnicity (if available), and the rate and risk of macular edema will be assessed for each strata. The incidence rate for macular edema will be calculated for a 1-10 years follow-up periods. Furthermore, the cumulative incidence will be assessed using the Aalen Johansen estimator. The stratified groups will be compared using a cox proportional hazard model to quantify the differences between the respective groups. Patients will be excluded if essential information is missing in their medical journal. Follow-up will terminate in case the patient moves to an address outside the North Denmark Region.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
