    Background Patients with initially low visual acuity were excluded from the therapy approval studies for retinal vein occlusion. But up to 28 % of patients presenting with central retinal vein occlusion have a baseline BCVA of less than 34 ETDRS letters (0.1). The purpose of our study was to assess visual acuity and central retinal thickness in patients suffering from central retinal vein occlusion and low visual acuity (<0.1) in comparison to patients with visual acuity (≥0.1) treated with Dexamethasone implant 0.7 mg for macular edema. Methods Retrospective, controlled observational case study of 30 eyes with macular edema secondary to central retinal vein occlusion, which were treated with a dexamethasone implantation. Visual acuity, central retinal thickness and intraocular pressure were measured monthly. Analyses were performed separately for eyes with visual acuity <0.1 and ≥0.1. Results Two months post intervention, visual acuity improved only marginally from 0.05 to 0.07 (1 month; p = 0,065) and to 0.08 (2 months; p = 0,2) in patients with low visual acuity as compared to patients with visual acuity ≥0.1 with an improvement from 0.33 to 0.47 (1 month; p = 0,005) and to 0.49 (2 months; p = 0,003). The central retinal thickness, however, was reduced in both groups, falling from 694 to 344 μm (1 month; p = 0.003,) to 361 μm (2 months; p = 0,002) and to 415 μm (3 months; p = 0,004) in the low visual acuity group and from 634 to 315 μm (1 month; p < 0,001) and to 343 μm (2 months; p = 0,001) in the visual acuity group ≥0.1. Absence of visual acuity improvement was related to macular ischemia. Conclusions In patients with central retinal vein occlusion and initially low visual acuity, a dexamethasone implantation can lead to an important reduction of central retinal thickness but may be of limited use to increase visual acuity

    Background: We report a 35-year-old female patient with cerebral manifestations of chronic graft-versus-host disease (cGvHD) and putative retinal involvement after allogeneic peripheral blood stem cell transplantation (alloHSCT). Patient and Methods: The patient experienced recurrent episodes of fever and encephalitic signs 7 months after alloHSCT during taper of immunosuppression (IS). Results: Cerebral magnetic resonance imaging (MRI) showed non-gadolinium-enhancing confluent periventricular lesions and cerebrospinal fluid inflammation. After exclusion of infectious causes, treatment with steroids and antiepileptics improved cognitive deficits. Steroid reduction provoked a relapse responding to IS. 2 years later, she complained of right-sided blurred vision and floaters; both eyes showed whitish circumscribed retinal infiltrations, cellular infiltration of the vitreous and mild bilateral optic disc edema. Oncological and neurological work-up ruled out infectious diseases and other GvHD manifestations. Symptoms and signs resolved under continued systemic IS, leaving pigmented retinal scars. After IS withdrawal, classical cutaneous cGvHD developed, resolving on systemic IS. 94 months after transplantation, she is doing well. Conclusion: To our knowledge, this is the first observation of retinal involvement of cerebral cGvHD manifestations with retinal infiltrations documented in the absence of other causes and in parallel to periventricular lesions in cerebral MRI. Based on bone marrow histology, we discuss a small vessel pathophysiology of cGvHD

    Background graft-versus-host disease (GvHD) is a common complication after allogeneic haematopoietic stem cell transplantation (allo-SCT) and causes immunological rejection of host tissues, which can occur both acute or chronically. Approximately 40-80% of patients with the diagnosis of chronic GvHD (cGvHD) also develop ocular GvHD. For these patients, immediate and uncomplicated access to interdisciplinary patient-centred care is important. We performed this survey to improve understanding of the structure of patient-centred care in Germany. Methods The GvHD working party of the Cornea Section of the German Society of Ophthalmology sent the Survey of ocular GvHD 2016 to all university and specialised hospitals in Germany. We evaluated the data and compared the information with survey results from 2014, in order to draw conclusions about the structure and process of patient-centred care in ocular GvHD. Besides the questions from 2014 on the numbers of allo-SCT, frequency of examinations, etc. there were additional questions on the prescription of ciclosporin and autologous serum eye drops. The question on frequency examination was further expanded to include examinations of paediatric patients. Results Of 30 participating hospitals, 22 had already taken part in the first survey. According to the information they provided, approx. 1860 allo-SCTs were performed in the transplantation units of the participating eye hospitals in 2016. This was more than half of the transplantations performed in Germany. Ophthalmologists examined between 2 and 250 Patients per year per centre. Eight clinics provide a specialised outpatient clinic for ocular GvHD. Nearly all the participating clinics prescribe ciclosporin eye drops. About 2/3 provide autologous serum eye drops, seven obtain them from external sources. Overall approx. 125- 140 children were examined in 2016. Conclusions Due to the potential severity of ocular GvHD with immobilisation of the patients and the imminent loss of sight, further improvements in eye care are required. For example, offers such as special consultations, with expertise located close to any transplantation unit are recommended. This requires in particular ophthalmologists to participate in the patient care to enhance quality of life after allo-SCT. In summary, we conclude that the present structures are not sufficient to treat all patients suffering from ocular GvHD in Germany, but the situation has evidently improved

    The purpose of the study was to validate a recently proposed new grading system for ocular manifestations of chronic graft-versus-host disease (cGVHD). Diagnosis of cGVHD was based on the NIH consensus criteria. In addition, a grading scale was applied, which has been developed by the German-Austrian-Swiss Consensus Conference on Clinical Practice in cGVHD. Sixty-six patients (male n=46, female n=20, mean age 48 years) with ocular cGVHD were included. Application of the proposed Consensus Conference grading revealed inflammatory activity in all patients with mild (33 %), moderate (44 %), or severe inflammation (23 %). Clinical scoring by the NIH scoring system showed that 6 % of patients had mild symptoms; 59 % of patients had moderate dry eye symptoms partially affecting activities of daily living, without vision impairment; and 35 % of patients had severe dry eye symptoms significantly affecting daily activities. Clinical characterization and grading by the Consensus Conference grading scale revealed that ocular cGVHD (1) frequently leads to severe ocular surface disease based on impaired function of the lacrimal glands and involvement of cornea, conjunctiva, and lids; (2) is mostly associated with ongoing inflammatory activity; (3) often leads to functional impairment and reduced quality of life; and (4) is associated with an increased risk for severe, sight-threatening complications

    Purpose To evaluate the outcome of phacoemulsification in patients with chronic ocular Graft-versus-host disease (oGVHD) after allogeneic hematopoietic stem cell transplantation (aHSCT). Methods Retrospective, observational multicenter study from 1507 oGVHD patients. From the patient files, data were collected including best-corrected visual acuity (BCVA), intraocular pressure (IOP), Schirmer's test I, tear film break-up time (TFBUT), corneal fluorescein staining score, postoperative complications, and pre- and post-operative topical therapy. Results Seventy-three patients underwent cataract surgery in 104 eyes. In n = 84 eyes, the oGVHD NIH grade was documented; 12% (n= 12) of analyzed eyes were staged oGVHD NIH grade 1, 31% (n= 32) NIH 2 and 39% (n = 41) NIH 3. The mean BCVA improved in 82% of the eyes (n = 86 eyes). BCVA significantly increased from 0.7 +/- 0.5 to 0.4 +/- 0.4 LogMAR after surgery independent from oGVHD severity. The mean IOP decreased from 14 +/- 4 to 13 +/- 4 mmHg after surgery. Visual acuity was moderately correlated to the pre-operative degree of corneal staining (Pearson p = 0.26, p = 0.002, Cohen's effect size f= 0.29). The visual acuity decreased by 0.078 LogMar units (95% CI =0.027-0.141) with each increase of corneal staining by one grade (p = 0.05). After surgery, corneal epitheliopathy increased significantly in 42% (n = 44) of the eyes. Postoperative complications included corneal perforation (n = 6, 6%), cystoid macular edema (n = 4, 4%), and endophthalmitis (n =1 , 1%) . Conclusion Phacoemulsification in patients with chronic oGVHD significantly improves visual acuity, but is associated with an increased risk of complications in particular corneal epitheliopathy and corneal perforations

    Survey of Rejection Prophylaxis Following Suture Removal in Penetrating Keratoplasty in Germany

    No full text
    Background Penetrating keratoplasty (PK) gets more and more reserved to cases of increasing complexity. In such cases, ocular comorbidities may limit graft survival following PK. A major cause for graft failure is endothelial graft rejection. Suture removal is a known risk factor for graft rejection. Nevertheless, there is no evidence-based regimen for rejection prophylaxis following suture removal. Therefore, a survey of rejection prophylaxis was conducted at 7 German keratoplasty centres. Objective The aim of the study was documentation of the variability of medicinal aftercare following suture removal in Germany. Methods Seven German keratoplasty centres with the highest numbers for PK were selected. The centres were sent a survey consisting of half-open questions. The centres performed a mean of 140 PK in 2018. The return rate was 100%. The findings were tabulated. Results All centres perform a double-running cross-stitch suture for standard PK, as well as a treatment for rejection prophylaxis with topical steroids after suture removal. There are differences in intensity (1-5 times daily) and tapering (2-20 weeks) of the topical steroids following suture removal. Two centres additionally use systemic steroids for a few days. Discussion Rejection prophylaxis following PK is currently poorly standardised and not evidence-based. All included centres perform medical aftercare following suture removal. It is assumed that different treatment strategies show different cost-benefit ratios. In the face of the diversity, a systematic analysis is required to develop an optimised regimen for all patients

    National Institutes of Health Consensus Development Project on Criteria for Clinical Trials in Chronic Graft-versus-Host Disease: IV. The 2020 Highly morbid forms report

    No full text
    Chronic graft-versus-host disease (GVHD) can be associated with significant morbidity, in part because of nonreversible fibrosis, which impacts physical functioning (eye, skin, lung manifestations) and mortality (lung, gastrointestinal manifestations). Progress in preventing severe morbidity and mortality associated with chronic GVHD is limited by a complex and incompletely understood disease biology and a lack of prognostic biomarkers. Likewise, treatment advances for highly morbid manifestations remain hindered by the absence of effective organ-specific approaches targeting irreversible fibrotic sequelae and difficulties in conducting clinical trials in a heterogeneous disease with small patient numbers. The purpose of this document is to identify current gaps, to outline a roadmap of research goals for highly morbid forms of chronic GVHD including advanced skin sclerosis, fasciitis, lung, ocular and gastrointestinal involvement, and to propose strategies for effective trial design. The working group made the following recommendations: (1) Phenotype chronic GVHD clinically and biologically in future cohorts, to describe the incidence, prognostic factors, mechanisms of organ damage, and clinical evolution of highly morbid conditions including long-term effects in children; (2) Conduct longitudinal multicenter studies with common definitions and research sample collections; (3) Develop new approaches for early identification and treatment of highly morbid forms of chronic GVHD, especially biologically targeted treatments, with a special focus on fibrotic changes; and (4) Establish primary endpoints for clinical trials addressing each highly morbid manifestation in relationship to the time point of intervention (early versus late). Alternative endpoints, such as lack of progression and improvement in physical functioning or quality of life, may be suitable for clinical trials in patients with highly morbid manifestations. Finally, new approaches for objective response assessment and exploration of novel trial designs for small populations are required.
