Different types of CNV in exudative AMD can be visualized and differentiated with OCT-A. Type 1 CNV were larger with minor demarcation from the surrounding vasculature and were visible on the slab "mid-choroid", "CC" and "RPE". In contrast, type 2 CNV demonstrated a sharp demarcation from the surrounding vasculature reaching the slab "outer retina".

Purpose Retinal pigment epithelium (RPE) tears may develop as a complication after anti-VEGF (vascular endothelial growth factor) treatment for pigment epithelial detachments (PEDs) in exudative age-related macular degeneration (AMD). This retrospective study analyses best-corrected visual acuity (BCVA) and foveal involvement after RPE tears that are associated with anti-VEGF therapy due to PED in exudative AMD. Methods A total of 37 patients with RPE tears during anti-VEGF therapy (bevacizumab 12, ranibizumab 21 and pegaptanib 4 eyes) for progressive PED in AMD (PED with occult choroidal neovascularization 25 eyes and PED with retinal angiomatous proliferation 12 eyes) were included in this study. We analyzed BCVA and different morphologic aspects by means of appearance on fluorescein angiography and optical coherence tomography. Mean follow-up was 88 weeks. Results RPE tears were diagnosed a mean of 56 days after the first injection. BCVA deteriorated after RPE tear and during follow-up significantly (Po0.001), with 53.2% of eyes being legally blind (WHO, world health organization) at 12 months. RPE-free foveal area, foveal wrinkling of the RPE, and fibrotic scar development were significantly associated with worse visual acuity. Discussion RPE tears can be observed in 12-15% of treated eyes during anti-VEGF therapy for PED in exudative AMD. Owing to the close time relationship with the therapy, this complication must be taken into consideration. Visual prognosis is associated with a decrease in vision in the long term, often resulting in a severe visual disability. Relevant factors for a negative visual prognosis were the potential foveal involvement of the central RPE and morphologic fibrovascular transformation of the RPE tear.

Aims To investigate the therapeutic effects of different treatments on serous pigment epithelium detachment (PED) in age-related macular degeneration (AMD). Methods A total of 328 patients suffering from serous PED in AMD were retrospectively analysed. We treated only patients with documented visual deterioration: 86 patients with bevacizumab, 128 with ranibizumab, 60 with pegaptanib, and 54 with photodynamic therapy (PDT) combined with intravitreal triamcinolone acetonide (IVTA). Bestcorrected vision was determined in the logarithm of the minimal angle of resolution (logMAR). We also analysed morphological findings such as full foveal thickness by optical coherence tomography (OCT), manually calculated height of PED as measured by OCT, and fluorescence angiography. Results The mean follow-up was 42.4 weeks. The best-corrected visual acuity of 0.78 logMAR before treatment could be improved by about 0.066 logMAR after treatment. Retinal thickness decreased in all patients with PED, in the mean by about 64.06 lm, and the mean value of the manually calculated height decreased by about 0.98 units. All functional and morphological results proved to be significantly better after injection of ranibizumab and bevacizumab than after pegaptanib and the combined treatment with PDT and IVTA. In all, 41 (12.5%) of our patients developed a tear of the retinal pigment epithelium (RPE). Conclusion The therapeutic results were significantly better in patients treated with bevacizumab and ranibizumab than in those treated with pegaptanib or with a combination of PDT and IVTA. Even with treatment, tears of the RPE or only a partial flattening of the PED always indicated a worse prognosis in eyes with exudative AMD than in eyes with classic choroidal neovascularization.

Purpose: To compare the effect of orbital floor (OFTA) or intravitreal (IVTA) administration of triamcinolone acetonide on visual acuity and chronic cystoid macular edema (CME) in patients with uveitis. Methods: Retrospective study of patients suffering from chronic noninfectious uveitis in whom CME (n = 97) did not respond to systemic corticosteroids and/or immunosuppression combined with acetazolamide. Patients received a single injection of either IVTA (n = 48, group 1) or OFTA (n = 49, group 2). Best-corrected visual acuity, macular edema (fluorescein angiography), uveitis activity, ocular hypertension, and cataract formation were analyzed over the course of 1 year. Results: Improvement in visual acuity (≥2 lines, LogMAR) was noted in 50% (IVTA) and 34% (OFTA) after 3 months (p = 0.23), and in 18% (IVTA) and 20% (OFTA) after 12 months. CME improved in 100% (IVTA) and 76% (OFTA) of the eyes within the first month postoperatively (p = 0.36). Macular edema was reduced in 100% (group 1) and 20% (group 2) after 3 months (p < 0.01). At 1 year, cataract progression was noted in 68% (IVTA) and 27% (OFTA) (p < 0.01). Increased intraocular pressure (>21 mm Hg) was detected in 21% (IVTA) and 0% (OFTA) at 4 weeks (p < 0.01) after injection. Conclusion: Uveitic CME and visual acuity not responding to systemic immunosuppression and acetazolamide may improve after an IVTA and OFTA injection. The effect is mostly transient. While the IVTA injections were more effective for improving CME, ocular hypertension and cataracts developed more often.

The flexible, predominantly visual acuity-driven ranibizumab retreatment regimen employed in clinical practice in Germany generally resulted in a loss of initially gained VA during 12 months of follow-up. Subgroup analysis showed that this negative effect was especially present in patients with relatively bad VA at treatment entry as well as the highest visual gain. Because this result demonstratse that a visual acuity-related retreatment regimen can not preserve the initial positive treatment effects with ranibizumab in exudative AMD, a revision of this schematic retreatment regimen used in Germany and adaptation to more sensitive retreatment parameters is recommended.
