Iris and macular angiography in intraocular implants

Iris fluorescein angiography in clinical practice

Iris fluorescein angiography is a valuable technique for elucidating a wide range of eye pathologies, among them developmental anomalies, degenerative disease, retinal vascular occlusions, diabetic microangiopathy, uveitis of various etiologies, glaucoma, tumor, and surgical or accidental trauma. In fact, IFA is more sensitive than biomicroscopy in the evaluation of iris abnormalities. Moreover, it provides indirect but reliable information on the retinal circulation when this cannot be examined directly. Some of the most important clinical applications involve the early detection of iris new vessels, cataract management in diabetic patients, and monitoring of iris tumors. Equipment, procedures, and fluorescein angiography patterns in normal and disease states are described and extensively illustrated. More widespread use of this valuable technique is encouraged.

Pseudophakic cystoid macular edema with the Severin lens

Clinically significant cystoid macular edema confirmed by fluorescein angiography has been studied in a consecutive series of 285 eyes having intracapsular cataract extraction and Severin intraocular lens implantation. The incidence and natural course of the condition is described and associated factors are discussed.
