ABSTRACT To describe visual acuity and angiographic outcomes of juxtafoveal choroidal neovascularization (CNV) treated with photodynamic therapy and verteporfin (PDT).
Four hundred eighty-four consecutive eyes of 446 patients treated with PDT from January 1, 2001, to June 30, 2002, were identified from billing records. Fluorescein angiograms were reviewed retrospectively to identify juxtafoveal CNV. Eligible patients had CNV in which the central boundary of the lesion was between 1 and 199 microm from the geometric center of the foveal avascular zone (FAZ). Patient charts were reviewed for visual acuity of the treated eye before PDT and at 6- and 12-month follow-up examinations. Presence of subfoveal CNV at 6 and 12 months of follow-up was determined by review of fluorescein angiograms. A lesion was considered subfoveal if it extended underneath the geometric center of the FAZ.
Twenty-one eyes had juxtafoveal CNV. Median change in visual acuity both 6 and 12 months after the initial PDT was 0 lines (n = 18 at 6 months, range -14 to + 8 lines; n = 17 at 12 months, range -18 to + 7 lines). Eleven lesions progressed to a subfoveal location by 12 months. Visual acuity in eyes with progressive lesions decreased a median of 4 lines of vision.
Despite a small sample size and limited length of follow-up, this study shows that visual acuity on average can remain stable for at least 12 months after PDT of juxtafoveal lesions. Growth through the foveal center still can occur, however, and this can be associated with substantial visual loss.

    ABSTRACT: To evaluate the efficacy of intravitreal ranibizumab with a "pro re nata" regimen in the treatment of nonsubfoveal neovascular membranes secondary to age-related macular degeneration. Retrospective noncomparative case series. Thirty-one eyes with naive nonsubfoveal neovascularization secondary to age-related macular degeneration were consecutively enrolled and treated with ranibizumab intravitreal injections according to a pro re nata regimen. The follow-up was performed monthly up to 6 months and quarterly up to 2 years (25 patients). Early treatment diabetic retinopathy study best-corrected visual acuity and lesion size analysis with fluorescein angiography were recorded. The mean baseline early treatment diabetic retinopathy study best-corrected visual acuity worsened from 20/40 (0.28 logMAR) at baseline to 20/50 (0.42 logMAR) at 1-year follow-up and 20/60 (0.53 logMAR) at 2-year follow-up. The mean lesions size nearly doubled from baseline at the 2-year follow up (1.19-2.47 mm). Twenty-two patients had one or more recurrences at 1-year follow-up. All 25 patients developed a recurrence at 2 years with 7 cases developing a recurrence by 12 months. Twelve cases progressed to subfoveal lesions by the 24-month visit. Other regimens described in the literature might result in a more the satisfactory outcome using more frequent follow-up and more frequent intravitreal injections.

    ABSTRACT: A blue laser system for eye diseases (age related macular degeneration, sub-retinal neo-vascularisation in myopia and presumed ocular histoplasmosis syndrome - POHS) photo-dynamic therapy, based on riboflavin as photosensitive substance, has been developed. A CW diode laser at 445 nm wavelength was coupled through an opto-mechanical system to the viewing path of a bio-microscope. The laser beam power in the irradiated area is adjustable between 1 mW and 40 mW, in a spot of 3-5 mm diameter. The irradiation time can be programmed in the range of 1-19 minutes. Currently, the laser system is under clinic tests.
