Abstract
Fluorescein angiography (FFA) and optical coherence tomography
(OCT) scans are important tools used in the examination and management of
retinal diseases. These investigative modalities complement to each other, and
many situations require both imaging methods to make the correct diagnosis
and treatment plan. This article compares the two technologies in various
clinical situations.
Fluorescein angiography provides retinal circulation details, and OCT
offers high-quality anatomic images. Fluorescein angiography is invasive, nonquantitative,
and subjective, with limited use for patients with small pupils or
insufficient media clarity. Optical coherence tomography is objective and is
not so much affected by pupil size or media clarity. Registration of OCT scans
helps clinicians properly assess patients during follow-up visits. Both
diagnostic tools depend heavily upon patient cooperation. Both are useful, and
often complimentary, in the diagnosis and management of a variety of retinal
disorders.
The aim of work is a comparison between fluorescein angiography and
optical coherence tomography in detection of macular changes of retinal
vascular disorders and to detect points of strength and weakness in each of
them
The present study is a observational, retrospective, longitudinal study.
Patients were recruited the outpatient retina clinic at Ophthalmology
Department; Tanta University during the period from December 2014 to May.
