Retrospective case series of juxtafoveal choroidal neovascularization treated with photodynamic therapy with verteporfin.
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: This prospective, open label, non-comparative, observational case series evaluates 6-month results of Pegaptanib Sodium (Macugen) and Photodynamic Therapy (PDT) in predominantly classic juxtafoveal choroidal neovascularisation (CNV) in age-related macular degeneration (AMD) in seven eyes of seven patients. Best corrected visual acuity (BCVA) diminished with a mean of five letters. Initial area of CNV increased significantly from 1.4 mm2 to 2.7 mm2. There was a significant increase in the greatest linear dimension (GLD) from 1280.3 microm to 2065.7 microm at the 24-week follow-up. Predominantly classic juxtafoveal CNVs are highly aggressive lesions that demonstrate poor response despite combined therapy using PDT and Macugen.The British journal of ophthalmology 02/2008; 92(1):74-5. · 2.92 Impact Factor

ABSTRACT: To evaluate the effects of verteporfin photodynamic therapy (PDT) on choroidal neovascularization (CNV) at the edge of chorioretinal atrophy in eyes with pathologic myopia. Twenty eyes of 20 consecutive patients were treated according to Verteporfin in Photodynamic Therapy criteria. The patients were divided into 3 groups based on CNV location and were followed up with clinical and fluorescein angiographic examinations to evaluate visual acuity (VA) changes and number of treatments. The mean follow-up was 35 months. In group 1 (n = 8; subfoveal CNV), VA declined from 20/73 (0.56 ± 0.26 logMAR) to 20/115 (0.76 ± 0.30 logMAR; p = 0.192). In group 2 (n = 6; juxtafoveal CNV), VA improved from 20/69 (0.54 ± 0.25 logMAR) to 20/46 (0.36 ± 0.16 logMAR; p = 0.176). In group 3 (n = 6; extrafoveal CNV), VA worsened from 20/50 (0.40 ± 0.21 logMAR) to 20/91 (0.66 ± 0.49 logMAR; p = 0.292). PDT showed inhibitory effects on myopic CNV arising at the edge of chorioretinal atrophy, especially in young adult myopic eyes with juxtafoveal neovascular membranes.Ophthalmologica 01/2011; 225(3):161-8. · 1.41 Impact Factor
