Customized Multiple Orbital Wall Decompression for Sight-threatening Graves's Ophthalmopathy

November 17, 2022 updated by: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

Customized Modified Multiple Orbital Wall Decompression With Fat Removal for Sight-threatening Graves's Ophthalmopathy : a Retrospective Cohort Study

Graves' orbitopathy (GO) is an disfiguring and disabling autoimmune condition. Sight-threatening GO is an most severe form and occurs in about 5% of patients with Graves' disease. It can cause blurred vision, color vision and vision function damage, and affects the quality of life. The goal of this retrospective cohort study is to propose a customized orbital decompression algorithm for patients with sight-threatening Graves'ophthalmopathy and to explore the therapeutic effect of customized orbital decompression in sight-threatening patients.

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

18 years to 65 years (Adult, Older Adult)

Probability Sample

Study Population

This was a retrospective cohort study of patients with sight-threatening Graves orbitopathy (GO) who underwent customized/individual multiple orbital wall decompression plus fat removal at Sun Yat-Sen Memorial Hospital from Jan. 2017 to Dec. 2021.

Description

Inclusion Criteria:

  • Sight-threatening patients undergoing interdisciplinary discussion and orbital decompression operation.
  • The sight-threatening GO refer to those with DON, exposure keratitis or corneal breakdown.
  • DON was diagnosed according to the following clinical findings including optic nerve head edema, visual field defect, impaired color vision, afferent pupil defect, retinal folds, radiologic evidence of apical optic nerve compression or globe subluxation.
  • Diagnosis of exposure keratitis or corneal breakdown was made based on physical exam signs, e.g. microepithelial defects, abrasion or ulcer. A minimum follow-up of 12 months was required for inclusion.

Exclusion Criteria:

  • Patients were excluded if exophthalmos, rather than acute visual loss, was the indication for surgery.
  • Cases with a history of previous ocular surgery, glaucoma, and visual defects from other ocular conditions were excluded from the study.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Single Group Assignment
patients with sight-threatening Graves orbitopathy (GO) who underwent customized/individual multiple orbital wall decompression plus fat removal
Procedure: Modified multiple orbital wall decompression
Thyroid dysfunction of all patients is stabilized by ATDs until treatment of TAO is completed. All patients with sight-threatening GO were admitted for emergency steroid pulse therapy. And additional drugs for protecting gastrointestinal mucous membrane, potassium and calcium supplements, and sedatives were used. All emergency cases, whose signs of visual impairment clinically attributable to GO existed despite first-line steroid treatment, were referred and discussed at the surgical board of our interdisciplinary center for prompt surgical orbital decompression. Urgent orbital decompression was performed when response is absent or poor within 1-2 weeks.

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.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion (Anticipated)

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.
