Retrospective Case Series of Trans-scleral Cryotherapy for Retinal

Status Active, not recruiting

Clinical Trial Summary

Background: Retinal hemangioblastoma (RH) is a tumor. It grows from the retina in the eye. It can threaten a person s vision. Trans-scleral cryotherapy is used to destroy the tumors and minimize the long-term risks of vision loss. RH is a rare condition, often occurring in people with von Hippel-Lindau disease. There are no clinical trials to study how well the treatment works. Researchers want to study the medical records of people with RH who were treated at the NIH eye clinic to learn more. Objective: To analyze clinical data collected over a 20-year span to study consecutive cases of RH managed with trans-scleral cryotherapy at the NIH. Eligibility: People who took part in NIH natural history protocols for which cryotherapy of RH was performed as a standard care measure. Design: Researchers will collect and study data from participants medical charts. Participants will not be contacted because no new data is needed. Researchers were granted a waiver of informed consent for use of these medical records. To protect patient privacy, participants will be assigned an ID number. Their data will be entered into a spreadsheet in a coded fashion. The key to this code will be kept in a secure file. No patient identifying information will be used in the analysis or the publication....

Clinical Trial Description

Study Description: This study is a retrospective review of medical records in the NIH eye clinic. To our knowledge, there has been no report in the current era dedicated to a description of trans-scleral cryotherapy for retinal hemangioblastomas despite its routine use in this setting. This study aims to explore features and outcomes of these cases to better inform best practices. Objectives: The objective of this study is to perform a retrospective analysis of consecutive cases of retinal hemangioblastoma managed with trans-scleral cryotherapy at the NIH (single center retrospective case series). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
