Abstract Details



Purpose:

To evaluate diabetic maculopathy features by fluorescein angiography (FA) and compare them with optical coherence tomography angiography (OCT-A) for analysis of the retinal microvasculature in diabetic maculopathy.

Setting:

Ophthalmology department. Habib Thameur Hospital. 8 street Ali Ben Ayed Montfleury 1008 Tunis, TUNISIA

Methods:

In a prospective serial case reports, 20 patients with diabetic maculopathy underwent routine clinical examination, FA and OCT-A (Triton Swept-Source OCT-Angiography). The retinal microvasculature of posterior pole was analysed in the superficial capillary plexus and deep capillary plexus using 4,5x4,5 mm OCT-A angiograms.

Results:

A total of 38 diabetic maculopathy were evaluated with FA and OCT-A. Microaneurysms were identified both by FA and OCT-A but their intraretinal depth was exactly localized by OCT-A using superficial and deep capillaries plexa. Non-perfusion areas were identified with OCT-A in all cases.

Conclusions:

OCT-A is noninvasive technique that offers several advantages over FA. It can provide additional information regarding the localization and morphology of microvascular lesions of posterior pole in diabetic maculopathy.
