Abstract

Background: Utilization of OCT angiography and en face analysis allowed the detection of 20 microns of subclinical leakage, with associated exudates, in a patient with idiopathic juxtafoveal telangiectasia type I.  Previously, the vascular mass was interpreted as a dot blot hemorrhage near the macula.   This patient case shows the value in detecting subclinical macular edema via advanced imaging techniques.

Case Report: A 69-year old Hispanic female presented to the office with a presumed dot blot hemorrhage temporal to the macula in the right eye that was diagnosed at her last eye exam one-year prior.   At her most recent comprehensive eye exam, the same vascular mass, approximately 250 microns in size with well-defined borders, was still seen slightly temporal to the macula.  Upon further analysis with OCT, the vascular mass was found to be intraretinal with an adjacent cyst in the interplexiform layer.  The patient was diagnosed with idiopathic juxtafoveal telangiectasia type I.  OCT angiography and en face analysis allowed breakdown of individual retinal layers and revealed 20 microns of leakage with associated exudates in the outer plexiform layer.

Conclusion: This case suggests a need for further research regarding the use of advanced imaging techniques for diagnosis and management of idiopathic juxtafoveal telangiectasia.  With advanced OCT analysis now available, the use of more invasive methods may not be a necessary option for detection and monitoring of macular edema.
