LONG-TERM EFFICACY OF FLUOCINOLONE IN EYES WITH IRIS-LENS DIAPHRAGM DISRUPTION AND PCME WITH MEDICATION FIXED IN THE SCLERA (MEFISTO).

PURPOSE: The aim of our prospective off-label, interventional clinical trial was to evaluate the efficacy and safety of the fluocinolone-loop-anchoring technique over two years in eyes with iris-lens diaphragm disruption and pseudophakic cystoid macular edema. METHODS: In 10 eyes, scleral fixation of fluocinolone implant was performed. Main outcome measures were the development of best-corrected visual acuity (BCVA), central retinal thickness over 24 months, and general safety of the procedure. RESULTS: A significant improvement to 0.57 ± 0.38 log MAR (Snellen 20/80) (range 0-1.30) was observed (P = 0.003) at 1 month. Further improvement to 0.45 ± 036 log MAR (Snellen 20/60) was observed until month 18 (P = 0.081). Mean central retinal thickness decreased by 22% from 601.6 ± 235.5 µm to 449.1 ± 128.9 µm at 1 month. In one patient, the implant has to be removed at Month 7 because of elevated intraocular pressure and one patient after globe rupture had a retinal redetachment at Month 4. CONCLUSION: In this study, we showed that the treatment of recalcitrant pseudophakic cystoid macular edema with scleral fixated fluocinolone implant in eyes with disruption of the iris-lens diaphragm provides good anatomical and functional results with a reasonable safety profile over 24 months in eyes where pseudophakic cystoid macular edema is otherwise difficult to treat and often left untreated.

Optimal Patient Adherence and Long-Term Treatment Outcomes of Neovascular Age-Related Macular Degeneration in Real-Life.

PURPOSE: To report on long-term real-life outcomes of anti-vascular endothelial growth factor (anti-VEGF) therapy in neovascular age-related macular degeneration (nAMD) with optimal patient adherence. METHODS: For this retrospective monocenter study, we identified 3217 eyes of 2793 patients that received a minimum of three intravitreal anti-VEGF injections for nAMD therapy between 2006 and 2014 at the University Eye Hospital Munich. From those, we included eyes with treatment-naïve nAMD, follow-up (FU) of ≥60 months and continuous adherence during FU. Primary measures were corrected visual acuity (VA), number of injections and visits as well as treatment regimen. RESULTS: We included 161 eyes of 125 patients with a mean FU of 8.0 ± 2.3 years. Mean VA at baseline was 60.1 letters (Snellen equivalent, 20/63). After the third year, mean VA declined constantly by 2-3 letters per year. After 5 and 8 years, 26.1% and 42.1% had lost at least 3 lines from baseline. Mean cumulative number of injections was 5.3 after the first year, and 23.9, 38.1, 48.5 after 5, 8, and 10 years. "Treat and extent" regimen with higher injection frequency correlated with better function. At time of last FU, 69.8% of eyes were under active treatment. Eyes with ≥70 letters at baseline correlated with better VA at the end of FU. CONCLUSIONS: Despite optimal patient adherence, visual function declined progressively in real-life nAMD therapy over long-term. The highest impact on treatment success is given by an early treatment start with individual but intensive anti-VEGF therapy.

Vanishing pachy-choroid in pachychoroid neovasculopathy under long-term anti-vascular endothelial growth factor therapy.

BACKGROUND: To investigate the diagnostic value of choroidal thickness in the definition of pachychoroid neovasculopathy (PNV), especially in eyes treated with anti-vascular endothelial growth factor (VEGF) therapy. METHODS: Twenty-two consecutive eyes of 11 patients with uni- or bilateral PNV were analyzed. Anti-VEGF treatment was correlated with changes in choroidal thickness on enhanced depth imaging optical coherence tomography. RESULTS: There were 14 eyes with PNV and 8 non-neovascular partner eyes. Mean age was 64.2 ± 4.0 (range: 60-72), total follow-up was 1.8 ± 0.4 (1-2) years. In PNV eyes, choroidal thickness at baseline was 400 ± 58 (269-485) µm. After two years and 13 anti-VEGF injections on average, a mean reduction of - 39 ± 10 (- 26 to - 56) % to final 241 ± 52 (162-327) µm was observed (p < 0.0001). Meanwhile, choroidal thickness in the partner eyes remained stable (p > 0.13 for all comparisons). A significant correlation of choroidal thinning and anti-VEGF injection rate was observed at year one (r = - 0.79; R2 = 0.63; p = 0.00073) and two (r = - 0.69; R2 = 0.48; p = 0.019). While 85.7% of PNV eyes exceeded a pachychoroid threshold of ≥350 µm at baseline, this figure dropped to 21.4% at year one and 0% at year two. CONCLUSION: In PNV, choroidal thickness significantly decreases with anti-VEGF therapy, resembling a "vanishing pachy-choroid", and thus does not represent a valid long-term diagnostic criterium, especially when differentiating PNV from nAMD.

Subthreshold laser therapy with a standardized macular treatment pattern in chronic central serous chorioretinopathy.

PURPOSE: There is an ongoing controversial debate about the effectiveness of laser treatments in chronic central serous chorioretinopathy (cCSC). We performed a prospective non-randomized interventional study to learn about the effects of a subthreshold laser treatment (Topcon Endpoint Management™, Topcon Healthcare Inc., Tokyo, Japan) in patients with cCSC. METHODS: Patients with cCSC and a minimum symptom duration of 4 months were included and treated with a standardized laser pattern covering the macular area. Retreatment was performed every 3 months if persistent subretinal fluid was observed. The primary endpoint was resolution of subretinal fluid at 6 months. Further outcome parameters included best corrected visual acuity, microperimetry, central macular and subfoveal choroidal thickness. RESULTS: A total of 42 eyes of 39 patients were included. Mean patient age was 48 ± 10.6 years (range 25-67). Mean symptomatic time before inclusion into the study was 134 ± 133.4 weeks (16-518). Before inclusion, 78.6% of the patients had failed to resolve subretinal fluid under mineralocorticoid receptor antagonists and 14.3% had a recurrence after half-dose photodynamic therapy. Complete resolution of subretinal fluid was observed in 42.9% at 6 months and in 53.8% at 12 months after baseline. Central retinal thickness decreased from 398 ± 135 µm to 291 ± 68 µm (p < 0.001), subfoveal choroidal thickness changed slightly (430 ± 116 µm to 419 ± 113 µm, p = 0.026), microperimetry-derived macular function improved by 19.1 ± 4.7 dB to 21.3 ± 4.8 dB (p = 0.008) and mean BCVA improved by 4.9 ± 8.6 ETDRS letters (p < 0.001). CONCLUSION: The results show that the investigated laser treatment is effective in reducing subretinal fluid and leads to an improvement of functional parameters.

[Retinal imaging of vitreomacular traction diseases]. / Retinale Bildgebung bei traktiven vitreomakulären Erkrankungen.

Advances in imaging techniques of the retina have substantially enhanced our current understanding of the pathogenesis, morphology and prognosis of vitreomacular retinal diseases. Optical coherence tomography-based criteria and classification systems were recently proposed for uniform diagnoses and treatment recommendations for patients with vitreomacular traction, epiretinal gliosis and the various forms of macular holes. This article provides an overview of the different retinal imaging modalities as well as the currently recommended classification for vitreomacular traction pathologies.

Ranibizumab non-response in pachychoroid neovasculopathy: Effects of switching to aflibercept.

Non-response to intravitreal ranibizumab represents a frequent problem in pachychoroid neovasculopathy (PNV). To investigate the effectivity of switching to aflibercept, the database of the Ludwig Maximilians University, Munich, was screened for patients fulfilling the following inclusion criteria: (i) diagnosis of PNV; (ii) inadequate response to ≥ 3 ranibizumab injections, in spite of monthly dosing, defined as persistence of subretinal-fluid four weeks after the last ranibizumab injection; (iii) resulting switch to aflibercept administered as three monthly injections. Primary outcome measure was percentage of eyes with a dry macula four weeks after the third aflibercept injection. Secondary outcome measures included changes in maximum subretinal fluid (SRF), central subfield thickness (CST) and subfoveal choroidal thickness (SFCT). In total, 14 eyes of 14 patients were included. Mean age was 64.1 ± 7.5 (range: 51-78) years. Switching to aflibercept was performed after mean 8.4 ± 4.1 (3-15) ranibizumab injections. While no eye (0%) achieved a dry macula status during ranibizumab treatment, switching to aflibercept achieved a dry macula status in eight eyes (57.1%) after three injections. While both ranibizumab and aflibercept showed an effect on CST (p = 0.027, p = 0.003), only aflibercept showed a significant effect on SRF (p = 0.0009) and SFCT (p = 0.044). In cases of PNV not responding to intravitreal ranibizumab, switching treatment to aflibercept induces a favorable short-term response resolving persistent fluid and achieving a dry macula. Further studies with longer follow-up are warranted.

Scleral Fixation of the Fluocinolone Acetonide Implant in Eyes with Severe Iris-Lens Diaphragm Disruption and Recalcitrant CME: The Fluocinolone-Loop-Anchoring Technique (FLAT).

INTRODUCTION: While proven to be an effective treatment for cystoid macular edema (CME) and diabetic macular edema, intravitreal steroid implants (IVSI) may cause undesirable side effects, including steroid-related glaucoma or migration into the anterior chamber in the case of iris-lens diaphragm disruption. Here we present a new surgical technique that allows for the easy implantation and subsequent fixation of the fluocinolone acetonide intravitreal implant without the risk of migration as a feasible and possibly reversible approach in the treatment of persistent CME in severely damaged eyes. METHODS: In this single-center, prospective off-label, proof of principle, scleral fixation of the fluocinolone implant was performed in two eyes with disrupted anterior-posterior segment border and persistent CME. Both eyes were then followed monthly in accordance to a detailed protocol. RESULTS: The procedure was overall well tolerated without severe side effects. There was no migration of the implant in the anterior chamber in either eye. CONCLUSION: Scleral fixation of the fluocinolone implant proved to be a safe and feasible approach in eyes with persistent CME and disrupted anterior-posterior segment border. This new technique also allows for the possible removal of the implant and may therefore be suitable even for eyes at higher risk for side effects, such as glaucoma.

Evaluation of a short-term topical interferon α-2b treatment for histologically proven melanoma and primary acquired melanosis with atypia.

OBJECTIVE: To evaluate the efficiency of series of 6-week treatments with brief intervals (6-week = 1 cycle) of topical Interferon α-2b (IFNα-2b) treatment in primary acquired melanosis (PAM) with atypia and melanoma of the conjunctiva. PATIENTS AND METHODS: Five patients with biopsy-proven PAM with atypia and seven patients with melanoma of the conjunctiva, treated with topical IFNα-2b (1 million units/ml, 5 times daily), were included in the study. All patients had colour photographs and the tumour area was measured manually for each patient before and after treatment. RESULTS: The median age of 12 patients at initiation of treatment was 61.5 years (range 39-75 years). The mean therapy duration was 2.4 cycles (range 1-6 cycle). Compared to pretreatment lesion dimension, the mean decrease in tumour size were after the first cycle 66% (range 18-98%; p = 0.004; n = 10 patients), after the second cycle 55% (range 10-100%; p = 0.016; n = 7 patients), and after the third cycle 74% (range 23-100%; n = 3 patients). In one patient 6 cycles of topical IFNα-2b were needed. The decrease in size was 22% after the 4(th) cycle, 34% after the 5(th) cycle, and 98% after the 6(th) cycle. CONCLUSION: Our clinical experience demonstrates promising results of topical IFNα-2b treatment for PAM with atypia and melanoma of the conjunctiva without any local or systemic side effects. However, future multicenter prospective studies are recommended to confirm the efficiency and safety of topical IFNα-2b treatment.

Utility values in patients with acquired anophthalmus.

BACKGROUND: Loss of an eye can be supposed to lead to reduced health-related quality of life. This can be due to monophthalmia in acquired anophthalmus and/or because of cosmetic impairment. Meanwhile several methods exist to evaluate the quality of life and the impairment in utility values in patients with ophthalmological diseases. METHODS: Twenty-three patients who underwent enucleation of one eye with good visual acuity of the fellow eye (>20/30) were included. All patients were asked to complete a standardized time trade-off (TTO) utility assessment form as well as the self-administered National Eye Institute Visual Function Questionnaire 25 (VFQ 25). TTO was assessed for restoring vision (TTO-A) and for restoring cosmetic appearance (TTO-B). RESULTS: The mean TTO value for visual function (TTO-A) was 0.87, the mean TTO value for cosmetic restoration (TTO-B) was 0.90 with a significant correlation. These values are surprisingly high compared to current TTO data. Visual acuity of the last eye and utility values were not correlated. TTO was not influenced by the underlying diagnosis. Patients older than 50 years were willing to trade off relatively more years than younger patients. TTO values were independent from the duration of the acquired anophthalmus. The mean VFQ-25 composite score was 81.0 and significantly lower than in the normal population. There was no significant correlation between TTO and the VFQ-25 composite score or any of the 12 subscales of the VFQ-25. CONCLUSION: Utility of patients with acquired anophthalmus and good vision of the last eye is very similar to patients with two eyes of which one is worse and good binocular vision. The VFQ-25 is no predictor for time trade-off.
