Trial record 2 of 9 for:    sickle cell retinopathy

New, Previously Unknown, Uses of Optical Coherence Tomography Angiography (OCTA) (OCTA)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03068702
Recruitment Status : Completed

Brief Summary:
Sickle cell maculopathy was sparingly mentioned in the literature before despite the fact that sickle cell disease or sickle cell trait is common in people of many areas of the world. This study shows that OCTA is a very valuable, non invasive, office procedure that may well be used in diagnosing this disease.

Condition or disease Intervention/treatment
Sickle Cell Retinopathy Device: Optical Coherence Tomography Angiography

Detailed Description:
this is a clinical study of two African Canadian patients that were diagnosed with sickle cell trait. I used OCTA to show macular vascular occlusions that usually happen with this disease.

Study Type : Observational
Actual Enrollment : 2 participants
Observational Model: Case-Only
Time Perspective: Retrospective
Official Title: New, Previously Unknown, Uses of Optical Coherence Tomography Angiography (OCTA): Sickle Cell Maculopathy
Actual Study Start Date : August 21, 2016
Actual Primary Completion Date : January 12, 2017
Actual Study Completion Date : February 21, 2017

Group/Cohort Intervention/treatment
African Canadians
African Canadians with sickle cell disease maculopathy diagnosed by OCTA.
Device: Optical Coherence Tomography Angiography

Primary Outcome Measures :
  1. vascular changes seen in the macular vasculature of people with sickle cell disease/ trait as compared to macular vasculature of normal macula. [ Time Frame: through study completion, an average of one year ]
    in this angiography the delicate vasculature of the macula can be clearly visualized and documented.
