Introduction:

HRA (Heiderberg Retina Angiograph) 2 uses a confocal scanning laser system which can provide high quality digital images but its imaging field is only 30°at most. HRA2 with a wide-field contact lens system allows an imaging field of up to 150°.

Methods:

We examined the advantages and disadvantages of HRA2, with a wide-field contact lens, for the evaluating diabetic retinopathy (DR).

Results:

HRA2 was beneficial for obtaining images of the entire retina simultaneously, without missing peripheral retinal non-perfusion and neovascularization. On the other hand, clear images connot be acquired in cases with media opacities such as corneal dystrophy, cataract and asteroid hyalosis, or in those with yellow tinted IOL.

Conclusions:

HRA2 with a wide-field contact lens is useful for visualizing peripheral retinal lesions in DR cases.

Keywords: : Heidelberg retina angiograph 2, wide-field contact lens, diabetic retinopathy.
