1/5. Macular translocation for subfoveal choroidal neovascularization in angioid streaks.PURPOSE: To report a case of visual improvement after macular translocation performed for a subfoveal choroidal neovascular membrane in a patient with pseudoxanthoma elasticum and angioid streaks. methods: The fovea was translocated inferiorly by scleral imbrication, intentional retinal detachment with a small posterior retinotomy, and partial fluid-air exchange. The choroidal neovascular membrane was photocoagulated 1 week later. RESULTS: The visual acuity of the patient improved from 20/125 to 20/40. The center of the foveal avascular zone was moved inferiorly 844 microm. The choroidal neovascular membrane was extrafoveal after translocation and was treated with laser photocoagulation. CONCLUSION: Macular translocation may be considered in the management of subfoveal choroidal neovascular membrane in patients with pseudoxanthoma elasticum and angioid streaks.- - - - - - - - - - ranking = 1keywords = neovascularization (Clic here for more details about this article) |
2/5. Reticular-like pigmentary patterns in pseudoxanthoma elasticum.Of 14 consecutive patients with pseudoxanthoma elasticum (PXE), 9 (64%) had a spectrum of peculiar, sometimes reticular, pigmentary changes in the retina. Ten of 18 (56%) eyes had a random scattering of small, round pigment dots throughout the macula and around the optic nerve, sometimes extending to the equator. In four of 18 (22%) eyes, the pigment clumps appeared in lines, resembling a string of pearls. These strings occasionally radiated from the macula in a spoke-like fashion. In 4 of the 18 (22%) eyes, the pigment clumping occurred in a fishnet, or truly reticular, pattern. Of the 18 eyes in these 9 patients, 12 (67%) had subretinal neovascularization. Of the ten eyes in the five patients who did not show this pigmentary change, two (20%) had subretinal neovascularization.- - - - - - - - - - ranking = 0.5keywords = neovascularization (Clic here for more details about this article) |
3/5. angioid streaks associated with pseudoxanthoma elasticum in a 13-year-old patient.This report describes a 13-year-old girl who presented with angioid streaks associated with pseudoxanthoma elasticum (PXE). Extensive retinal pigment epithelial (RPE) mottling, known as peau d'orange, characteristic of PXE, was also noted. The potential complication of choroidal neovascularization is described. physicians should be aware that angioid streaks and their potentially sight-threatening complications can occur in this age group.- - - - - - - - - - ranking = 0.25keywords = neovascularization (Clic here for more details about this article) |
4/5. Laser treatment of choroidal neovascular membranes in angioid streaks.Eight patients with active extrafoveal choroidal neovascular membranes related to angioid streaks were studied. One eye of each of four patients was treated with argon laser. Two patients received bilateral treatment. Four patients received multiple treatments at different times for recurrence of neovascular membranes. Two patients were not treated. The visual acuity of the treated eyes remained the same or improved posttreatment, with one exception. The majority of untreated eyes lost vision. The vast majority of the treated eyes showed a marked improvement in central visual field posttreatment, whereas the untreated eyes remained the same or lost considerably more central visual field. In one to four years after treatment, recurrences of the neovascular membranes occurred in four of the treated eyes demonstrating that these cases must be followed indefinitely. Carefully selected cases appear to benefit from complete obliteration of choroidal neovascularization by argon laser photocoagulation.- - - - - - - - - - ranking = 0.25keywords = neovascularization (Clic here for more details about this article) |
5/5. 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. Within areas of chorioretinal atrophy they are not visualized. The 'peau d'orange' appearance is much better visualized by indocyanine green angiography than by fluorescein angiography. indocyanine green angiography further characterizes choroidal neovascularization, which is the major complication of angioid streaks. CONCLUSION: indocyanine green angiography contributes to the visualization of alterations in Bruch's membrane such as angioid streaks and the 'peau d'orange' appearance.- - - - - - - - - - ranking = 0.25keywords = neovascularization (Clic here for more details about this article) |
