Enhanced Depth Imaging Optical Coherence Tomography A New Method in Diagnosis and Evaluation of Treatment for Choroidal Hemangioma: A Case Report

Purpose: To report the evaluation of the treatment response in choroidal hemangioma with application of enhanced depth imaging optical coherence tomography (EDI-OCT) technique Case report: A 73-year-old woman with a circumscribed choroidal hemangioma in the posterior pole of her left eye underwent photodynamic therapy and intravitreal injection of bevacizumab. EDI-OCT obtained from the affected eye before and after the treatment. The efficacy of treatment evaluated with indocyanine green and fluorescein angiography (FA). Results: The EDI-OCT taken before treatment showed increased thickness of choroidal layer as multiple large dark spaces in the outer and middle layers of the choroid. After treatment, EDI-OCT revealed shrinkage of the choroidal thickness (from 712 μm to 273 μm) more pronounced in outer and middle layers. Conclusion: EDI-OCT may be used as a noninvasive test to help in the diagnosis and evaluation of the treatment response and follow-up of patients with choroidal hemangioma.
