Purpose: To report the indocyanine green angiography findings in a case of acute idiopathic blind spot enlargement syndrome., Method: The patient underwent ophthalmologic examination with fluorescein angiography and indocyanine green angiography., Results: A monocular enlarged blind spot was found on automated perimetry; fluorescein angiography showed a hypofluorescent peripapillary atrophic area and indocyanine green angiography highlighted diffuse, small hypofluorescent spots scattered throughout the posterior pole. Visual field defects and indocyanine green angiography abnormalities resolved over 4 weeks., Conclusion: Indocyanine green angiography in acute idiopathic blind spot enlargement syndrome showed many lesions not visible with fluorescein angiography, indicating a choroidal involvement reaching not only the peripapillary area but the entire posterior pole.

Purpose: To highlight the possible role of indocyanine green angiography in predicting future exudative changes in eyes that are candidates for drusen laser treatment., Methods: In a 56-year-old woman, fluorescein and indocyanine green angiography were performed before drusen laser treatment., Results: The treated eye had a suspicious lesion at baseline indocyanine green angiography and a nonsuspicious fluoroangiographic pattern. Seven months after treatment, the patient developed choroidal neovascularization and pigment epithelial detachment in the treated eye., Conclusion: To decrease the risk of macular exudative changes that may be related to laser treatment, eyes that are candidates for drusen laser treatment should be examined before treatment, not only by fluorescein angiography, but also by indocyanine green angiography.

A randomized prospective study on two groups of ten patients compared the efficacy of diode laser and argon laser trabeculoplasty. In the diode laser group the intraocular pressure was 23.0 +/- 3.97 mm Hg before the treatment, 20.2 +/- 4.49 mm Hg at two hours, 16.3 +/- 3.13 at six months, and 16.9 +/- 2.80 mm Hg at one year. The differences from baseline were statistically significant at six months (P = .0001) and at one year (P = .0001) but not at two hours. In the argon laser group the intraocular pressure was 23.4 +/- 3.6 mm Hg before the treatment, 22.7 +/- 4.35 mm Hg at two hours, and 17.6 +/- 4.53 mm Hg at six months. One patient had uncontrolled mean high intraocular pressure and underwent surgery. In the nine patients who completed the study the intraocular pressure at one year was 16.7 +/- 3.00 mm Hg. The differences from baseline were significant at six months (N = 10; P = .0001) and 12 months (N = 9; P = .0001) but not at two hours. Differences between the two groups were not significant at two hours, six months, and one year. Laser trabeculoplasty may be effectively with a diode laser.
