In particular, fluorescein angiography has become a very important tool in the diagnosis and treatment of chorio-retinal diseases. However, limitations of fluorescein angiography in imaging the choroidal circulation and associated pathologies prompted the use of alternative dyes to improve choroidal angiography.

Indocyanine green angiography is a diagnostic study where indocyanine green, a fluorescent dye, is injected intravenously, and observations of the retina are made at intervals as increasing intensity of retinal and choroidal circulation is displayed.

Indocyanine green angiography is used for the imaging of retinal and choroidal vasculatures. It is effective when used as an adjunct to fluorescein angiography in the diagnosis and treatment of ill-defined choroidal neovascularization i.

It is generally used in evaluating retinal neovascularization, serous detachment of retinal pigment epithelium, hemorrhagic detachment of retinal pigment epithelium, and retinal hemorrhage. Indocyanine green angiography has been under development for the past 30 years as an imaging method for the choroidal vasculature.

Although standard fluorescein angiography is widely used to evaluate exudative and proliferative lesions of the retina, its diagnostic ability in imaging the choroid is limited because of dye scatter by the overlying pigmented structures of the fundus, and also due to leakage of fluorescein through the fenestrated capillaries of the choroid.

Improvements in indocyanine green angiography, specifically the development of high resolution digital imaging systems, have permitted the technical feasibility and commercialization of the technology. The most commonly proposed application of indocyanine green angiography is the detection of choroidal neovascularization, a common component of age related macular degeneration.

A series of randomized studies in the s called the Macular Photocoagulation Study showed that patients with "classic" choroidal neovascularization could benefit from photocoagulation treatment.

Those with diffuse or poorly defined disease or disease involving the foveal avascular zone were considered poor candidates for photocoagulation.

With these criteria, it has been estimated that only about about half of patients would be candidates for treatment.

In as much as the key to the success of photocoagulation was accurate delineation of choroidal neovascularization, it was hoped that the improved diagnostic capabilities of indocyanine green angiography would lead to the identification of more patients who would be appropriate candidates for treatment.

Given the above discussion, an appropriate outcome for indocyanine green angiography would be its diagnostic capabilities compared to fluorescein angiography in the evaluation of patients with choroidal neovascularization. Yannuzzi and colleagues performed indocyanine green angiography on patients with age related macular degeneration and ill defined or occult neovascularization as identified by a previous fluorescein angiography.

A total of 12 patients underwent laser photocoagulation based on the indocyanine green videoangiography ICGA findings. Although the exact techniques may vary from study to study, several subsequent reports have also documented improved diagnostic capabilities of indocyanine green angiography compared to fluorescein angiography.

As discussed in the studies above, indocyanine green angiography is used as a second level diagnostic test to further evaluate patients with choroidal neovascularization.

Typically all patients will first undergo a fluorescein angiography which will simultaneously evaluate the retinal vasculature, and give initial information regarding the choroidal vasculature.

Background Before writing the letter, confirm the following:
Recent Posts M81 You are required to code to the highest level of specificity.

Fluorescein angiography can definitively identify some patients who are not candidates for photocoagulation i. Indocyanine green angiography is then appropriate in those patients with equivocal results with fluorescein angiography, or who require more accurate definition of the neovascularization before proceeding to photocoagulation therapy.

Therefore the appropriateness of indocyanine green angiography is contingent upon the results of fluorescein angiography. In an evidence review on the use of indocyanine green angiography in chorio-retinal diseases, Stanga et al stated that they do not recommend ICGA for scleritis and posterior scleritis, drusen differentiation, Behcet's disease Behcet's syndromeor sarcoidosis, because it has not been demonstrated to add useful clinical information.

Surgical management of macular holes consists of pars plana vitrectomy, removal of the posterior hyaloid facia, and peeling of the epi-retinal membranes ERM.

Additionally, removal of the internal limiting membrane ILM may enable an increase in the anatomical and functional success rates.

However, recognition of fine ILM is difficult; thus increasing the time that the macula is exposed to intra-operative light. However, there are some concerns about the intra-vitreal ICG application. Reports in the literature described a variety of application techniques using different concentrations.

The post-operative outcomes were controversial reporting heterogeneous anatomical and functional outcomes after ICG application, as well as descriptions of adverse effects related to the dye.
