Clinical Trial Summary

The study will perform to follow-up UC-MSCs and CM transplantation. 18 patients will be called back to be examined after 5 years of UC-MSC and/or CM transplantation.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Visual Acuity Test	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
Primary	Visual Field Test	a test to assess the breadth of views of the lateral, medial, superior and inferior aspects using Humprey's perimetry.	5 years after injection
Primary	Funduscopy	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
Primary	Electrorectinography	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
Primary	Optical Coherence Tomography (OCT)	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
Primary	Angiography	a process of taking photos of the retina by injecting fluorescent to get a bleeding location on the retina.	5 years after injection
