Real-world insights and outcomes related to ciclosporin A 0.1% cationic emulsion for the long-term treatment of dry eye disease in Germany: Country-level sub-analysis of the PERSPECTIVE study.

PURPOSE: The PERSPECTIVE study was a real-world European, non-interventional, multicenter, observational study that evaluated the effectiveness, tolerability, and safety of ciclosporin A (CsA) 0.1% cationic emulsion (CE) in routine clinical practice as a treatment for adults with severe keratitis and dry eye disease (DED) that remained insufficiently controlled with artificial tears. This sub-analysis examined data from ophthalmology clinics in Germany to provide more precise insights into treatment patterns, outcomes, and clinical decision-making related to CsA 0.1% CE. METHODS: Study data were collected from adults starting CsA 0.1% CE (one drop in both eyes at bedtime) and followed up at Week 4, 12, and 24, and Month 12. The primary endpoint was mean change from baseline in corneal fluorescein staining (CFS) score (Oxford Grade Scale) at Month 12. Secondary endpoints examined the severity of ocular signs and symptoms, and adverse events (AEs). RESULTS: A total of 236 patients from 20 ophthalmology clinics in Germany participated in the PERSPECTIVE study (69.9% female; mean age 60.8 years). Following treatment with CsA 0.1% CE, patients experienced significant reductions in CFS score from Week 4, which were maintained through to Month 12 (P < 0.0001). From baseline, 81.6% of patients experienced an improvement in CFS score at Month 12. CsA 0.1% CE provided significant reductions in the severity of eyelid and conjunctival erythema at Month 12 compared with baseline (P < 0.001), as well as significant reductions in the severity of subjective ocular symptoms (all P ≤ 0.015). Safety data were consistent with the known safety profile of CsA 0.1% CE. Tolerability was rated as "satisfactory," "good," or "very good" by 97.2% of physicians and 95.7% of patients. CONCLUSION: Outcomes in Germany were similar to those reported for the overall European study population and are indicative of the treatment results that ophthalmologists may expect to see with CsA 0.1% CE treatment in real-life clinical practice. Treatment with CsA 0.1% CE provided long-term improvements over 12 months and was generally well tolerated.

Real-World Effectiveness, Tolerability and Safety of Cyclosporine A 0.1% Cationic Emulsion in Severe Keratitis and Dry Eye Treatment.

INTRODUCTION: The PERSPECTIVE study evaluated, in routine clinical practice, the effectiveness, tolerability and safety of cyclosporine A (CsA) 0.1% cationic emulsion (CE) in controlling severe keratitis in adults with dry eye who remained insufficiently controlled despite artificial tear (AT) use. METHODS: A prospective, multicenter, observational study was conducted at 44 ophthalmology clinics across Finland, Germany, Norway, Sweden and the UK. Adults treated with ATs for severe keratitis and dry eye received CsA 0.1% CE therapy (1 drop in both eyes at bedtime) and were followed up at weeks 4, 12 and 24 and at month 12. Primary endpoint was mean [standard deviation (SD)] change from baseline in corneal fluorescein staining (CFS; Oxford Grade Scale) at month 12 following CsA 0.1% CE initiation. Secondary endpoints examined ocular sign and symptom severity and adverse events (AEs). RESULTS: The full analysis set included 472 adults (75.9% female). Mean (SD) age was 61.9 (15.41) years. Mean (SD) CFS score was significantly reduced from baseline [2.56 (1.10)] at month 12 [1.10 (SD 1.13); P < 0.0001]. CFS score reductions were statistically significant from week 4, with further incremental decreases reported at study visits through month 12 (P < 0.0001). Severity of eyelid and conjunctival erythema was significantly reduced from baseline at week 4 and maintained through month 12 (P < 0.001). Tear film breakup time increased significantly from baseline at all study visits through month 12 (P < 0.001). Ocular symptom severity was significantly reduced from baseline at all study visits through month 12 (P < 0.001). Overall, 101 treatment-related AEs were reported. Most were mild/moderate (83.6%) and resolved by month 12 (73.3%). CONCLUSIONS: In routine clinical practice, CsA 0.1% CE provided statistically significant reductions in dry eye signs and symptoms. Improvements were seen at week 4 and maintained over 12 months. Treatment tolerability was good and consistent with previous CsA 0.1% CE clinical studies.

[Adherence to anti-VEGF treatment-Considerations and practical recommendations]. / Adhärenz bei der Anti-VEGF-Therapie ­ Überlegungen und praktische Empfehlungen.

BACKGROUND: Numerous studies have identified a lack of treatment adherence as an important factor that often conflicts with the necessary number of anti-VEGF injections and therefore a better functional result. OBJECTIVE: This article discusses approaches and possible measures to reduce the risk of late and infrequent intravitreal injections leading to the major issue of undertreatment. MATERIAL AND METHOD: In the course of an expert dialogue, relevant parameters of treatment adherence and variables were identified. Meaningful processes were structured and assigned to organizational areas. RESULTS: The compilation of meaningful measures enables practitioners to optimize their own implementation in different areas. Regular monitoring measures can identify the extent of treatment interruption and discontinuation. For specific indicators (treatments per time interval, longest pause interval, minimum coverage per unit time, delay) an effect on the development of visual function was demonstrated. Organizational measures, training of teams and referring physicians, redundant and iterative information transfer to patients have been proven in the experience of experts. The firm integration of these processes into the structures is facilitated by working with checklists. CONCLUSION: An optimization of the processes is possible to improve the adherence and the functional results; however, interventional studies showing how adherence and persistence can be increased in the German treatment setting are still lacking.

Clinical and Ophthalmological Characteristics of Ocular Syphilis in a Retrospective Tertiary Hospital Cohort.

BACKGROUND: Data on ocular syphilis (OS) and its clinical presentation are currently insufficient. This study aimed to investigate the characteristics of a cohort with a high OS incidence at a university hospital in Germany, focusing on the clinical presentation of OS. METHODS: This single-center cohort study retrospectively analyzed data on 90 patients with 109 episodes of syphilis between 2008 and 2018. Cases of OS were identified and additionally reevaluated through a study-specific secondary assessment by an ophthalmologist specializing in uveitis. RESULTS: Twenty-three patients (26%) were diagnosed with OS, 16 (70%) of whom were with binocular involvement. Uveitis, especially that of the posterior segment, showed a high prevalence. Lumbar puncture was performed in 20 OS patients (87%), of whom 17 (85% of those with lumbar puncture/74% in total) met the 2018 Centers for Disease Control and Prevention criteria for likely neurosyphilis. Five (22%) of 23 patients had HIV infection, of whom 2 did not receive antiretroviral therapy. The preferred syphilis treatment regimens were benzylpenicillin and ceftriaxone, which yielded favorable serological, clinical, and ophthalmological outcomes. CONCLUSIONS: A high incidence of OS was identified, and physicians should be aware of uveitis as a manifestation of syphilis. Most patients presented with uveitis and syphilis in an early or late latent stage and showed central nervous system involvement.

Systematic review: non-adherence and non-persistence in intravitreal treatment.

PURPOSE: Intravitreal injection of VEGF inhibitors has become the standard of care for different macular diseases within the last years resulting in improved visual outcomes. Under real-life conditions, however, the necessity for frequent retreatments and reexaminations poses a burden for patients and treatment centers. Non-adherence and non-persistence to intravitreal treatment may lead to inferior clinical outcomes, and knowledge of contributing factors is crucial to improve adherence. This systematic review analyzes current literature for potential factors involved in non-adherence and non-persistence. METHODS: A systematic search was conducted in PubMed and Embase including three different aspects of intravitreal injection therapy: (1) diseases with intravitreal injections as treatment, (2) intravitreal injection, and (3) aspects of therapy adherence or therapy persistence. Data from identified quantitative studies were further extracted and grouped according to WHO criteria (condition, socio-economy, therapy, patient, and health system). The methodological quality of identified studies was graded. Identified qualitative studies (i.e., interviews) were descriptively analyzed and their findings narratively reported. RESULTS: Twenty-four publications were included. In 16 of those publications, a quantitative data analysis was conducted, analyzing factors associated with non-adherence. Worse visual acuity at baseline and unfavorable development of visual acuity, higher age, and greater distance to the treatment center were associated with non-adherence, while there was inconsistent evidence for an association of comorbidity. In qualitative studies, high follow-up/treatment burden, fear and anxiety, disappointed patient expectations, and lack of motivation to continue treatment were reported as reasons for non-persistence. CONCLUSIONS: Knowledge of potential barriers in IVT treatment may improve adherence and potentially clinical results. Improvements can be achieved particularly in the healthcare complex (organizational improvements) and the "patient" complex by establishing realistic expectations. Recurrent education of the patient may be necessary.

Systemic exposure to intracameral vs topical mydriatic agents: in cataract surgery.

OBJECTIVE: The objective of this study was to compare systemic exposure to tropicamide/phenylephrine following intracameral or topical administration before cataract surgery. PATIENTS AND METHODS: Mydriatics exposure was calculated in patients randomized to intracameral fixed combination of mydriatics and anesthetic ([ICMA]: tropicamide 0.02%, phenylephrine 0.31%, and lidocaine 1%, N=271) or mydriatic eye drops ([EDs]: tropicamide 0.5% and phenylephrine 10%, N=283). Additional doses were permitted if required. Mydriatic plasma levels were determined by mass spectrometric HPLC in 15 patients per group before and after administration. RESULTS: Most ICMA patients (73.6%) received a single dose (200 µL) representing an exposure to tropicamide of 0.04 mg and phenylephrine of 0.62 mg. None of these patients received additional mydriatics. In the control group (three administrations), the exposure was 0.45 (11.3-fold higher than ICMA) and 10.2 (16.5-fold higher) mg. When additional ED was used in this group (9.2% of patients), it was 37.5-fold higher for tropicamide (10 drops, 1.5 mg) and 54.8-fold higher for phenylephrine (10 drops, 34 mg) than the recommended ICMA dose. Tropicamide plasma levels were not detectable at any time point in ICMA patients while it was detectable in all ED patients at 12 and 30 minutes. Phenylephrine was detectable in 14.3% of ICMA patients compared to all ED patients at least at one time point. More ED patients experienced a meaningful increase in blood pressure and/or heart rate (11.2% vs 6.0% of ICMA patients; P=0.03). CONCLUSION: Systemic exposure to tropicamide/phenylephrine was lower and cardiovascular (CV) effects were less frequent with ICMA. This could be of particular significance in patients at CV risk.

[Vascular Biomarkers in Retinal Vessel Analysis]. / Vaskuläre Biomarker der retinalen Gefäßanalyse.

Modern non-invasive imaging procedures - including fundus photography and optical filming - can be used to investigate objective aspects of changes in the function and structure of retinal vessels. In the pre-, post- and capillary areas, the status and behaviour of retinal vessels passively and actively influence blood flow and flow-related metabolism through changes in vascular diameter. Retinal vessels have the same structure and function as cerebral vessels and reflect the status of the microcirculation. In dynamic retinal vessel analysis, the function and structure of the longitudinal section of retinal vessels are subjected to a non-invasive functional and structural examination over a period before, during and after a specific vascular stimulation. The exact methodology of the evaluation and the designation of the parameters depend on the investigation. Retinal vessel analysis has been employed in several cross-sectional and interventional clinical studies in ophthalmology and other specialities, including cardiology, neurology, neurosurgery, nephrology, gynaecology, sports medicine, diabetology, hypertensiology and others. Static retinal vessel analysis is an inexpensive, reproducible, non-invasive technique, which can be used to make a prognostic statement on the vascular health of an individual patient. Dynamic retinal vessel analysis possesses a broader spectrum of diagnostic applications than the static procedure, as it examines changes in vessel diameter continuously over time. The use of several different methodological modalities for retinal vessel analysis together with their relevant quantitative biomarkers represents a promising approach for the evaluation of vascular diseases and cerebro- or cardiovascular morbidity and mortality. Interdisciplinary clinical application of these vascular biomarkers is becoming increasingly important in ophthalmology and other specialities.

Enteric-coated mycophenolate sodium in the treatment of non-infectious intermediate uveitis: results of a prospective, controlled, randomised, open-label, early terminated multicentre trial.

BACKGROUND/AIMS: To evaluate the efficacy, safety and tolerability of enteric-coated mycophenolate sodium (EC-MPS) in combination with low-dose corticosteroids compared with a monotherapy with low-dose corticosteroids in subjects with non-infectious intermediate uveitis (IU). METHODS: Open-label, prospective, controlled, randomised multicentre trial. Patients were randomised in a 1:1 ratio to either the treatment group (prednisolone plus EC-MPS) or control group (prednisolone monotherapy). Patients in the control group who relapsed within 6 months changed to the crossover group (prednisolone plus EC-MPS). Maximum treatment duration was 15 months. The primary endpoint was the time to first relapse in the treatment group and control group. RESULTS: Forty-one patients at eight sites were analysed. Twenty-two patients were allocated to the treatment group, with 19 patients in the control group. A first relapse occurred in 9 patients (40.9%) in the treatment group and 15 patients (78.9%) in the control group (p=0.03). The median time to the first relapse was >15 months for the treatment group and 2.8 months for the control group (p=0.07). The probability of relapse-free survival at month 15 was estimated to be 52.9% in the treatment group and 19.7% in the control group (p=0.01). 15 patients changed to the crossover group. Of these, only four patients developed a second relapse. No safety concerns arose during the trial. Only one patient had to discontinue EC-MPS due to increased liver enzymes. CONCLUSION: EC-MPS can be considered an effective and well-tolerated immunosuppressive drug to prevent relapses in patients with chronic IU.

Comparison of the influence of aerobic and resistance exercise of the upper and lower limb on intraocular pressure.

PURPOSE: To compare the influence of aerobic and resistance exercise on intraocular pressure (IOP). METHODS: Twenty-one healthy subjects participated. Aerobic exercise was performed using a cycle ergometer, and resistance exercise was performed with a leg curl and a butterfly machine. Intraocular pressure was measured at baseline, during exercise and 10 min after. During resistance exercise, a Valsalva manoeuvre was prevented. RESULTS: Before aerobic exercise, the mean IOP was 18.8±2.7 mmHg. It was 16.5±2.8 after 10, 17.1±2.6 after 20 and 16.7±3.3 mmHg after 30 min of exercise. After 10 min, the IOP returned to baseline (18.8 ±2.7 mmHg). The mean IOP before resistance exercise with the leg curl machine was 17.0 (15.6-18.4; 65%Wmax ) and 16.8 (15.3-18.3) mmHg; 75%Wmax ) and did not change significantly during the experiment. The mean IOP before resistance exercise with the butterfly machine (65%Wmax ) was 16.4 (15.2-17.6) and increased to 17.2 (16.0-18.4) mmHg (p<0.05). After 10 min of recreation, it recovered to 16.3 (15.0-17.5) mmHg. At 75%Wmax , the mean baseline IOP was 16.3 (15.2-17.4) mmHg, and there were no significant changes. CONCLUSIONS: Aerobic exercise leads to a significant decrease of IOP. There was no influence of resistance exercise on IOP as long as a Valsalva manoeuvre was prevented.

Ocular perfusion pressure in glaucoma.

This review article discusses the relationship between ocular perfusion pressure and glaucoma, including its definition, factors that influence its calculation and epidemiological studies investigating the influence of ocular perfusion pressure on the prevalence, incidence and progression of glaucoma. We also list the possible mechanisms behind this association, and discuss whether it is secondary to changes in intraocular pressure, blood pressure or both. Finally, we describe the circadian variation of ocular perfusion pressure and the effects of systemic and topical medications on it. We believe that the balance between IOP and BP, influenced by the autoregulatory capacity of the eye, is part of what determines whether an individual will develop optic nerve damage. However, prospective, longitudinal studies are needed to better define the role of ocular perfusion pressure in the development and progression of glaucoma.

Preservative-free tafluprost in the treatment of naive patients with glaucoma and ocular hypertension.

PURPOSE: The study reported here investigated the efficacy, tolerability, and safety of the preservative-free prostaglandin analog tafluprost 0.0015% in treatment-naive patients. PATIENTS AND METHODS: Data were collected in two non-interventional, prospective, multicenter, observational, open-label studies of identical design that were conducted in Germany and the Czech Republic. All subjects received preservative-free tafluprost 0.0015% once daily. Intraocular pressure (IOP) levels were recorded for each eye at untreated baseline and 3 months after initiation of medical treatment. The primary outcome was change in mean IOP from baseline to month 3. In the primary open-angle glaucoma (POAG) and ocular hypertension (OH) patient subgroups, analyses were stratified by the level of baseline IOP: ≥20 to 23 mmHg versus ≥24 mmHg. In addition, responder rates and the achievement of pre-specified IOP levels at month 3 were evaluated. Local tolerance of preservative-free tafluprost was evaluated by the patients at final visit. Overall satisfaction with the medical treatment was evaluated by both patients and physicians. All adverse events were recorded. RESULTS: A total of 579 treatment-naive patients with POAG (n = 349), OH (n = 105), normal tension glaucoma (n = 71), exfoliative glaucoma (n = 27), or other glaucomas (n = 27) were included in this observational study. Mean IOP level at baseline for all patients was 23.6 ± 4.0 mmHg. Mean IOP at month 3 was 16.8 ± 2.9 mmHg (-28.8% vs baseline). At month 3, significant reductions in mean IOP (P < 0.001) were seen in all patients and all subgroups. Preservative-free tafluprost lowered mean IOP significantly in patients with POAG and OH with IOP levels ≥ 20 to 23 mmHg from 21.9 ± 1.1 mmHg at baseline to 16.5 ± 2.2 mmHg, and in the subgroup with IOP levels ≥ 24 mmHg from 26.2 ± 2.4 mmHg to 17.9 ± 2.4 mmHg. In the subgroups of patients with POAG and OH, an IOP response ≥20%, ≥30%, and ≥40% was achieved by 83.4%, 44.1%, and 12.8%, respectively. Overall, patients with higher baseline IOP values showed a better response than patients with lower baseline IOP levels. Preservative-free tafluprost was well tolerated and safe. After 3 months, 97.9% of all patients remained on therapy. CONCLUSION: In this real-world observational study, treatment with once-daily preservative-free tafluprost proved efficacious, well tolerated, and safe in treatment-naive patients.

Changes in the foveal microstructure after intravitreal bevacizumab application in patients with retinal vascular disease.

PURPOSE: To investigate changes in the area of the foveal avascular zone (FAZ) in patients with retinal vascular disease. PATIENTS AND METHODS: This retrospective, consecutive study examined 53 eyes of 53 patients with macular edema due to branch retinal vein occlusion in 25 patients (47.2%) and nonproliferative diabetic retinopathy in 28 patients (52.8%). The macular edema was treated with an intravitreal injection of 0.05 mL equal to 1.25 mg bevacizumab. Before and 6-8 weeks after the injection, best corrected visual acuity, slit lamp biomicroscopy of the anterior segment and fundus, optical coherence tomography, and fluorescein angiography were conducted. The FAZ was manually circumscribed on early-phase angiography images and the area of the FAZ was measured. RESULTS: The preoperative overall mean FAZ area was 0.327 ± 0.126 mm(2) (median 0.310 mm(2)). At the control consultation, the overall mean area was significantly larger (0.422 ± 0.259 mm(2); median 0.380 mm(2); P < 0.001). In the nonproliferative diabetic retinopathy subpopulation, the mean area was 0.361 ± 0.129 mm(2) (median 0.330 mm(2)) before bevacizumab application and 0.434 mm(2) at the follow-up visit (mean increase 0.071 mm(2)/19.7%). In the branch retinal vein occlusion group, the baseline FAZ area was 0.290 ± 0.115 mm(2) and 0.407 ± 0.350 mm(2) at follow-up (median 0.330 mm(2); mean increase 0.117 mm(2)/40.3%). No cases of severe operation-associated complications were observed. CONCLUSION: The results confirm the safety of intravitreal bevacizumab injection in patients with macular edema due to nonproliferative diabetic retinopathy and branch retinal vein occlusion. The enlargement of the FAZ could be equivalent to an increase in retinal ischemia. These results may be transient; a potential vascular risk, however, when applying antivascular endothelial growth factor therapy in eyes with preexistent vascular disease must be considered.

Does increased blood pressure rather than aging influence retinal pulse wave velocity?

PURPOSE: It was demonstrated previously that retinal pulse wave velocity (rPWV) as a measure of retinal arterial stiffness is increased in aged anamnestically healthy volunteers compared with young healthy subjects. Using novel methodology of rPWV assessment this finding was confirmed and investigated whether it might relate to the increased blood pressure usually accompanying the aging process, rather than to the aging itself. METHODS: A total of 12 young 25.5-year-old (24.0-28.8) [median(1st quartile-3rd quartile)] and 12 senior 68.5-year-old (63.8-71.8) anamnestically healthy volunteers; and 12 senior 63.0-year-old (60.8-65.0) validated healthy volunteers and 12 young 33.0-year-old (29.5-35.0) hypertensive patients were examined. Time-dependent alterations of vessel diameter were assessed by the Dynamic Vessel Analyzer in a retinal artery of each subject. The data were filtered and processed using mathematical signal analysis and rPWVs were calculated. RESULTS: rPWV amounted to 1200 (990-1470) RU (relative units)/s in the hypertensive group and to 1040 (700-2230) RU/s in anamnestically healthy seniors. These differed significantly from rPWVs in young healthy group (410 [280-500] RU/s) and in validated healthy seniors (400 [320-510] RU/s). rPWV associated with age and mean arterial pressure (MAP) in the pooled cohort excluded validated healthy seniors. In a regression model these associations remain when alternately adjusted for MAP and age. When including validated healthy seniors in the pooled cohort only association with MAP remains. CONCLUSIONS: Both aging (with not excluded cardiovascular risk factors) and mild hypertension are associated with elevated rPWV. rPWV increases to a similar extent both in young mildly hypertensive subjects and in aged anamnestically healthy persons. Healthy aging is not associated with increased rPWV.

Using TNF-alpha antagonist adalimumab for treatment for multisystem sarcoidosis: a case study.

We report the usage of the TNF-alpha antagonist adalimumab in patients with progressive multisystem sarcoidosis. Three patients with multisystem sarcoidosis (MSS) were treated with adalimumab for 12 months. All three patients were quickly responded to adalimumab and experienced a nearly complete regression of the symptoms that lead to an intensive immunosuppression. However, some accompanying symptoms of sarcoidosis, such as splenomegalia, did not respond. One patient suffered 18 months later a new unspecified abdominal lymphadenopathy. TNF-alpha antagonists can be helpful agents in the treatment for MSS. However, the experience with TNF-alpha antagonists in patients with sarcoidosis is still limited. Multicenter trials and a comparison of the different agents are needed to validate the safety and efficacy in these patients. Optimal dosage, duration of therapy and long-term toxicity of anti-TNF therapy in patients with refractory sarcoidosis are yet to be determined in prospective trials.

Use of colour Doppler imaging in ocular blood flow research.

The main objective of this report is to encourage consistent quality of testing and reporting within and between centres that use colour Doppler imaging (CDI) for assessment of retrobulbar blood flow. The intention of this review is to standardize methods in CDI assessment that are used widely, but not to exclude other approaches or additional tests that individual laboratories may choose or continue to use.
