Long-term chorioretinal changes after photodynamic therapy for chronic central serous chorioretinopathy.

PURPOSE: To evaluate morphological and functional chorioretinal changes 5 years after standard photodynamic therapy (PDT) for chronic central serous chorioretinopathy (CSC). METHODS: A retrospective, nonrandomized study, including patients with chronic CSC treated with standard PDT and followed for at least 60 months. All patients underwent a complete ophthalmological examination, and the location and number of treatments were registered. Five or more years after treatment, subfoveal and non-subfoveal treated areas were evaluated with Spectralis optical coherence tomography and microperimetry. RESULTS: Seventeen eyes of 15 patients were included, with mean age of 48.3 ± 8.4 years and a mean follow-up of 80.6 ± 12.4 months (range from 62 to 104 months). All eyes had neurosensory detachment (NSD) at baseline. Treatment was performed under the fovea in 58.8 % and in a non-foveal area in 41.2 % of the eyes. At the final visit all eyes had resolution of the NSD, with a statistical significant reduction in central macular thickness (p = 0.005) and preserved neuroretinal thickness (p = 0.839). There was a statistical difference between initial and final BCVA (p < 0.001) and a mean gain of 8.4 ± 7.8 letters. Subfoveal morphological changes in external limiting membrane (ELM) and in photoreceptor inner and outer segment junction (IS/OS) were correlated with final BCVA (p = 0.015 and p = 0.014 respectively), but not with the variation of BCVA. There was a statistical correlation between morphological changes in IS/OS line and retinal sensitivity in the central 12° and 2° (p = 0.003 and p = 0.002 respectively). The morphological changes in the subfoveal layers were not dependent on treatment location (p = 0.154, p = 0.644, and p = 1.0 for ELM, IS/OS line, and retinal pigment epithelium respectively). Subfoveal final mean choroidal thickness was 295.1 ± 68.7 µm, and showed no statistical difference from the normal population (p = 0.633). CONCLUSIONS: Morphological and functional chorioretinal changes, observed 5 or more years after standard PDT for chronic CSC, were not correlated with the location of treatment, neither with the progression of visual acuity or with the location of treatment, and are more likely to be related to the disease itself than with the treatment provided.

Long-term follow-up of myopic choroidal neovascularization treated with ranibizumab.

PURPOSE: To evaluate the long-term safety and efficacy of intravitreal ranibizumab in the treatment of myopic choroidal neovascularization (CNV). METHODS: Three-year retrospective, nonrandomized, interventional case series. Forty eyes of 39 patients with myopic CNV were included; 15 with previous photodynamic therapy, and 25 naïve eyes. Best-corrected visual acuity (BCVA) changes, central foveal thickness (CFT), and number of treatments were assessed, from baseline to month 36. RESULTS: Mean visual acuity improved from 55.4 Early Treatment Diabetic Retinopathy Study (ETDRS) letters at baseline to 59.7 letters at 12 months (p = 0.07), 61.8 letters at 24 months (p = 0.008) and 63.4 letters at 36 months (p = 0.039). Twenty-five percent of the patients gained ≥15 letters (3 lines) at 12 months, 30% at 24 months and 35% at 36 months. There was a mean reduction of 80 µm in CFT (p < 0.001). A mean of 4.1 injections were performed in the first year, 2.4 in the second year and 1.1 in the third year. Fifty-three percent of the eyes had no need for treatment during the third year of follow-up. CONCLUSIONS: Intravitreal ranibizumab seems to be an effective and safe therapeutic procedure to treat CNV in highly myopic eyes, with a high proportion of patients gaining or stabilizing BCVA at a 3-year follow-up.

Photodynamic therapy with verteporfin in polypoidal choroidal vasculopathy: results after 3 years of follow-up.

PURPOSE: The purpose of this study was to evaluate the efficacy of verteporfin photodynamic therapy on the treatment of polypoidal choroidal vasculopathy. METHODS: A prospective, nonrandomized institutional study was conducted involving 42 eyes of 38 patients with newly diagnosed symptomatic polypoidal choroidal vasculopathy treated exclusively with photodynamic therapy. Twenty-seven eyes completed 3 years of follow-up. Subjects were observed every 3 months with evaluation of best-corrected visual acuity (BCVA), retinography, and fluorescein and indocyanine green angiography. Treatment was given whenever the patient exhibited subfoveal exudation on fluorescein angiography. RESULTS: Mean BCVA was 0.91 +/- 0.33 logarithm of the minimum angle of resolution on the initial visit and 0.93 +/- 0.39 on the 36-month visit. Patients were submitted to an average of 3.19 treatment sessions. On the final evaluation at 36 months, 14.8% of the treated eyes improved their BCVA by at least 0.3 logarithm of the minimum angle of resolution, 74.1% had no significant loss of BCVA, and 25.9% lost >or=0.3 logarithm of the minimum angle of resolution. Recurrences were frequent (59.3% of the eyes at 3 years of follow-up), responded well to retreatment, and were not associated with additional BCVA loss. CONCLUSION: Photodynamic therapy remains a good option for management of polypoidal choroidal vasculopathy. After 3 years, approximately three fourths of the treated eyes had no significant loss of vision, and 14.8% showed significant improvement in visual acuity.

Intravitreal ranibizumab for myopic choroidal neovascularization: 12-month results.

PURPOSE: The purpose of this study was to evaluate the safety and efficacy of intravitreal ranibizumab after 12 months in the treatment of choroidal neovascularization secondary to pathologic myopia. METHODS: This was a prospective, multicenter, consecutive, nonrandomized, interventional case series. The study included 34 eyes of 32 patients with choroidal neovascularization secondary to pathologic myopia; 13 eyes had previous photodynamic therapy, and 21 eyes had no previous treatment. The patients were followed for > or = 12 months. Best-corrected visual acuity, optical coherence tomography, and the presence of metamorphopsia were assessed monthly. RESULTS: Mean visual acuity improved 8 letters from baseline to 12-month follow-up, and the difference was statistically significant (P < 0.001): 100% of the eyes lost <3 lines on the Early Treatment Diabetic Retinopathy Study chart, 24% of the eyes improved > or = 3 lines, 44% improved > or = 2 lines, 65% improved > or = 1 line, and 79% improved > or = 0 lines. Central retinal thickness decreased significantly from baseline to the 12-month follow-up (P < 0.01). A mean of 3.6 treatments were performed during the 12-month follow-up, and no systemic or ocular side effects were registered during that time. CONCLUSION: One-year results of intravitreal ranibizumab for myopic choroidal neovascularization are very promising. Additional prospective studies are necessary to better determine long-term efficacy and safety.

Chorioretinal anastomosis and photodynamic therapy: a two-year follow-up study.

BACKGROUND: To evaluate the two-year efficacy of photodynamic therapy with Visudyne (PDT) in neovascular age-related macular degeneration (AMD) eyes with chorioretinal anastomosis (CRA). METHODS: A non-randomized, institutional, prospective study, of 28 consecutive eyes of 23 patients, with CRA, treated with PDT. Masked best corrected visual acuity (VA) and angiographic features at baseline and during the period of two years were evaluated. RESULTS: Twenty eight eyes completed one year and 19 eyes completed two years of follow-up. The number of treatments was 3 in the first year, and 0.8 in the second year. A VA loss < 3 lines occurred in 53% of the eyes, at two years. Treated eyes lost 0.5 lines in the first year and 2.4 lines in the second (p < 0.01). Recurrence with additional significant VA loss occurred in four eyes (21%) during the second year. Fourteen eyes (74%) showed no fluorescein leakage at two years. CONCLUSION: AMD eyes with chorioretinal anastomosis can benefit from PDT with Verteporfin at two years. However, during the second year significant additional VA loss occurs mainly due to recurrence. New modalities of treatment are necessary to achieve VA improvement in CRA eyes.

Polypoidal choroidal vasculopathy and photodynamic therapy with verteporfin.

BACKGROUND: We evaluated, in a nonrandomised, institutional, prospective study, the efficacy of photodynamic therapy (PDT) with verteporfin in age-related macular degeneration (AMD) eyes with polypoidal choroidal vasculopathy (PCV) and subfoveal exudation. METHODS: A prospective clinical and angiographic study was done in 40 consecutive eyes with PCV treated with PDT using masked best-corrected visual acuity (VA) and fluorescein and indocyanine green angiographic features at baseline and over 2 years. RESULTS: Twenty-one eyes completed 1-year follow-up and showed, after a mean 2.9 PDT sessions, VA improvement in 12 eyes, no change in five eyes, and VA decrease in four eyes. Leakage was absent at the retinal and choroidal level in 14 eyes at 1 year. Recurrence occurred in one eye during the first year. Six eyes completed 2 years of follow-up and showed, after a mean 4 PDT sessions, VA improvement in five eyes and VA decrease in one eye. Leakage was absent at the retinal and choroidal level in five eyes. Recurrence occurred in four of these six eyes during the second year of follow-up. No serious adverse events were observed during the 2 years of follow-up. CONCLUSIONS: PDT with verteporfin was shown to be safe and effective for treating AMD eyes with PCV with subfoveal involvement. VA improvement and absence of leakage were achieved, respectively, in 57.1% and 66.6% of the eyes at 1 year. Recurrences were more frequent during the second year of follow-up.
