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.

Detailed Description

The study will be performed on 18 patients who received UC-MSC and CM transplantation in 2018. The study is included as retrospective cohort since the transplantation happened 5 years ago. Patients will do a visual field test, visual acuity test, electroretinography, funduscopy, and Optical Coherence Tomography examination. The observation results will be written in the observation table and analyzed by a statistic.The study will be performed at Rumah Sakit Jakarta Eye Center and Rumah Sakit Umum Pusat Dr. Sardjito Yogyakarta.

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)

Accepts Healthy Volunteers

No

Sampling Method

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
Visual Acuity Test
Time Frame: 5 years after injection
a test to see the sharpness of vision using Snellen Chart which is read at a distance of 6 meters. Normal eye test results are stated in 6/6.
5 years after injection
Visual Field Test
Time Frame: 5 years after injection
a test to assess the breadth of views of the lateral, medial, superior and inferior aspects using Humprey's perimetry.
5 years after injection
Funduscopy
Time Frame: 5 yeas after injection
an examination to see and assess the abnormalities and conditions in the ocular fundus using an ophthalmoscope. This examination is carried out by an ophthalmologist.
5 yeas after injection
Electrorectinography
Time Frame: 5 years after injection
an examination to provide a picture of objectivity, a quantitative measure of retinal function to monitor the function of stem cells and ganglion cells in the eye. This examination is carried out by a trained ophthalmologist.
5 years after injection
Optical Coherence Tomography (OCT)
Time Frame: 5 years after injection
is a diagnostic test that give the information about posterior segment structure, which is retina and optic nerve papillae so that it can be used to assess macular abnormalities
5 years after injection
Angiography
Time Frame: 5 years after injection
a process of taking photos of the retina by injecting fluorescent to get a bleeding location on the retina.
