One year of intravitreal injections of steroids.

Purpose: Chronic macular oedema sometimes does not respond to classic treatment such as laserphotocoagulation, periocular and systemic steroids or carbonic anhydrase inhibitors. High dose intravitreal injection of steroids can be a valuable alternative in these patients.

Methods: Sixty-four eyes of 51 patients with chronic macular oedema, refractory to conventional treatments, received an intravitreal injection of 4 mg Kenacort (triamcinolone acetonide).

Diabetes mellitus and the eye.

In Belgium as in other industrialized countries, diabetic retinopathy is still the most important cause of blindness in the active population group, but can be prevented by an early and adequate treatment. This highly socio-economic problem should therefore have priority with the autorities of the Belgian Health Department. The costs of a well-organized screening programme of the diabetic population are far less than the costs that arise from the economic and social consequences caused by irreversable visual loss, the costs of long and expensive treatments and long periods of inability to work, when advanced diabetic eye disease has developed.

Indocyanine green angiography is of value for the diagnosis of chronic central serous chorioretinopathy in elderly patients.

Background: Central serous chorioretinopathy is characterized on indocyanine green angiography by areas of transient choroidal hyperfluorescence. These findings are thought to be the consequence of altered permeability of the choroidal vessels.

Methods: The indocyanine green angiograms of 41 patients between 40 and 60 years of age, with central serous chorioretinopathy and of 120 patients above 64 years of age with occult choroidal neovascularization due to age-related macular degeneration were reviewed for the presence of transient indocyanine green leakage.

Comparison of fluorescein and indocyanine green angiography in angioid streaks.

Background: The main cause of vision loss in patients with angioid streaks is choroidal neovascularization and subsequent macular degeneration. Indocyanine green angiography allows visualization of the choroidal circulation and may be superior to fluorescein angiography in the evaluation of patients with angioid streaks.

Methods: The ophthalmoscopic, fluorescein and indocyanine green angiographic characteristics of angioid streaks were studied in 34 patients with such streaks.

Indocyanine green angiography in angioid streaks.

Purpose: To present the indocyanine green angiographic features of angioid streaks.

Methods: The angiographic findings of five typical cases, three cases of idiopathic angioid streaks and two pseudoxanthoma elasticum patients, are reported.

Results: In most cases angioid streaks are hyperfluorescent in the late venous and late phase of the indocyanine green angiogram.
