Abstract
Purpose: This work aims to assess the value of intravitreal triamcinolone acetonide (IVTA) as an adjunctive therapy in advanced Coats disease with exudative retinal detachment (ERD). Methods: A retrospective review was conducted of patients with Coats disease stage 3 or higher who received IVTA to decrease subretinal fluid (SRF), facilitate retinal ablative therapy, and avoid surgical drainage. Primary outcomes were SRF resolution and avoidance of surgical SRF drainage. Results: Seventeen eyes of 17 patients (mean, [SD] age, 3.9 [3.4] years) met the inclusion criteria. ERD configuration was bullous in 7 and shallow in 10 eyes. Following a single IVTA injection, ablative therapy was achieved after a mean (SD) of 2.1 (3.0) weeks. Complete SRF resolution was observed in 13 eyes (76.4%) after a mean of 1.3 IVTA injections and a mean of 2 (SD, 1.27) laser sessions, and none of these eyes required SRF drainage up to last follow-up (mean [SD], 50.5 [26.24] months). In 4 eyes with bullous ERD at presentation, SRF persisted ( P = .015) despite additional measures including surgical drainage. Final visual acuity ranged from 20/100 to no light perception. Cataract developed in 12 of the 17 eyes (70.5%). None developed an increase in intraocular pressure at final follow-up. Conclusions: IVTA injection can be a helpful adjunctive modality to address SRF in advanced Coats disease. It may obviate the need to surgically drain SRF to effectively treat the condition, particularly when the ERD is not highly bullous.

Abstract
Interstitial lung diseases (ILDs) other than idiopathic pulmonary fibrosis (IPF) have an array of immunomodulatory treatment options compared with IPF, due to their inflammatory component. However, there is a relative paucity of guidance on the management of this heterogeneous group of diseases. In ILDs other than IPF, immunosuppression is the cornerstone of therapy, with varying levels of evidence for different immunomodulatory agents and for each specific ILD. Classification of ILDs is important for guiding treatment decisions. Immunomodulatory agents mainly include corticosteroids, mycophenolate mofetil (MMF), azathioprine, methotrexate, cyclophosphamide and rituximab. In this review, the available evidence for single agents in the most common ILDs is first discussed. We then reviewed practical therapeutic approaches in connective tissue disease-related ILD and interstitial pneumonia with autoimmune features, scleroderma-related ILD, vasculitis and dermatomyositis with hypoxemic respiratory failure, idiopathic non-specific interstitial pneumonia, hypersensitivity pneumonitis sarcoidosis, fibrosing organizing pneumonia and eosinophilic pneumonia. The treatment of acute exacerbations of ILD is also discussed. Therapy augmentation in ILD is dictated by the recognition of progression of disease. Criteria for the evaluation of progression of disease are then discussed. Finally, specific protocol and measures to increase patients' safety are reviewed as well, including general monitoring and serologic surveillance, Pneumocystis jirovecii prophylaxis, patients' education, genetic testing for azathioprine, MMF serum levels and cyclophosphamide administration protocols. Immunomodulatory therapies are largely successful in the management of ILDs and can be safely managed with the application of specific protocols, precautions and monitoring.

Validation of the risk stratification score in idiopathic pulmonary fibrosis: study protocol of a prospective, multi-centre, observational, 3-year clinical trial. BMC Pulm Med 2021; 21:396. [PMID: 34863146 PMCID: PMC8645123 DOI: 10.1186/s12890-021-01753-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 11/18/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is characterized by a poor prognosis, with a progressive decline in lung function and considerable variability in the disease's natural history. Besides lung transplantation (LTx), the only available treatments are anti-fibrosing drugs, which have shown to slow down the disease course. Therefore, predicting the prognosis is of pivotal importance to avoid treatment delays, which may be fatal for patients with a high risk of progression. Previous studies showed that a multi-dimensional approach is practical and effective in the development of a reliable prognostic score for IPF. In the RIsk Stratification scorE (RISE), physiological parameters, an objective measure of patient-reported dyspnea and exercise capacity are combined to capture different domains of the complex pathophysiology of IPF. METHODS This is an observational, multi-centre, prospective cohort study, designed to reflect common clinical practice in IPF. A development cohort and a validation cohort will be included. Patients newly diagnosed with IPF based on the ATS/ERS criteria and multi-disciplinary discussion will be included in the study. A panel of chest radiologists and lung pathologists will further assess eligibility. At the first visit (time of diagnosis), and every 4-months, MRC dyspnea score, pulmonary function tests (FEV1, FVC and DLCO), and 6-min walking distance will be recorded. Patients will be prospectively followed for 3 years. Comorbidities will be considered. The radiographic extent of fibrosis on HRCT will be recalculated at a 2-year interval. RISE, Gender-Age-Physiology, CPI and Mortality Risk Scoring System will be calculated at 4-month intervals. Longitudinal changes of each variable considered will be assessed. The primary endpoint is 3-year LTx-free survival from the time of diagnosis. Secondary endpoints include several, clinically-relevant information to ensure reproducibility of results across a wide range of disease severity and in concomitance of associated pulmonary hypertension or emphysema. DISCUSSION The objective of this study is to validate RISE as a simple, straightforward, inexpensive and reproducible tool to guide clinical decision making in IPF, and potentially as an endpoint for future clinical trials. TRIAL REGISTRATION U.S National Library of Medicine Clinicaltrials.gov, trial n. NCT02632123 "Validation of the risk stratification score in idiopathic pulmonary fibrosis".

Abstract
Purpose Novel 3D digital display systems, such as NGENUITY 3D digitally assisted visualization system (DAVS), can provide enhanced illumination, depth of field, and digital filtering. This study compared vitreous removal using NGENUITY 3D DAVS with a standard surgical microscope. Methods This was an in vivo, 2-arm laboratory study in 15 Yorkshire pig eyes. The LuxOR LX3 microscope with NGENUITY 3D DAVS (arm 1) and the LuxOR LX3 microscope alone (arm 2) were used with 5× optical magnification and Oculus BIOM 200 mm optics. Standard core and peripheral vitrectomy without scleral depression was performed using the CONSTELLATION Vision System. Residual vitreous weight was assessed in enucleated eyes by a masked observer. Axial length and vitreous weight of contralateral eyes were compared from an additional 14 Yorkshire pigs to confirm that eyes from a single animal were essentially identical. Results After vitrectomy, mean ± SD residual vitreous was significantly smaller with NGENUITY versus standard microscope (0.143 ± 0.146 versus 0.580 ± 0.269 g, respectively; P < 0.0001). Based on a mean initial vitreous weight of 2.5 g, as determined by assessment in contralateral eyes from an additional 14 Yorkshire pigs, the mean percentage vitreous removal was 94% ± 6% versus 77% ± 11%, respectively. Further, vitreous weight and axial length for contralateral eyes from any single animal in these additional 14 animals were essentially identical, as mean differences were 0.046 ± 0.035 g and 0.11 ± 0.08 mm, respectively. Conclusion Vitrectomy with NGENUITY 3D DAVS resulted in significantly less residual vitreous in pig eyes compared with standard microscopy. NGENUITY may improve vitreous removal during vitreoretinal surgery by enhancing visualization.

Abstract
To report the outcomes, advantages and disadvantages of a heads-up three-dimensional (3D) visualization system compared to the conventional microscope in pediatric tractional retinal detachment (TRD) surgery secondary to advanced stage retinopathy of prematurity (ROP). Medical records of patients with ROP stage 4 or 5 who underwent surgery for tractional retinal detachment at King Khaled Eye Specialist Hospital between September 2017 and July 2019 were identified and reviewed. Eyes were divided into 2 groups, eyes that underwent surgery with a 3D heads-up platform (3D group) and eyes that underwent surgery with a conventional microscope (conventional group). Data were collected on neonatal history, visual acuity, intraoperative complications and success rates between groups.Eighteen eyes of 14 patients who underwent surgical repair of TRD related to ROP. Postoperative outcomes were compared between 10 eyes (7 patients) in the 3D group and 8 eyes (7 patients) in the conventional group There was no statistically significant difference in success rate between both groups (75% conventional group vs 70% 3D group). Partial or complete reattachment was achieved in 7 eyes in 3D group compared to 6 eyes in conventional group. Lower postmenstrual age at the time of the first surgery and presence of retinal breaks were associated with poorer surgical outcome. Heads up 3D visualization system is feasible in tractional retinal detachment related to ROP with similar success rate and no increased risk of complications when compared to conventional microscope. This system may be advantageous in advanced pediatric tractional retinal detachment surgeries.

Abstract
Purpose To compare the specificity of diagnosing posterior vitreous detachment (PVD) using preoperative optical coherence tomography (OCT) versus intraoperative triamcinolone acetonide (TA) staining in patients undergoing vitrectomy. Patients and Methods This retrospective cohort study included patients undergoing pars plana vitrectomy for diverse retinal pathologies. Intraoperatively, surgeons evaluated the posterior hyaloid status with TA staining and compared it with preoperative OCT findings. Results One hundred six patients underwent intraoperative assessments of posterior hyaloid status, with 72% (76/106) of the eyes showing positive staining. Sixty-two patients had also undergone preoperative OCT. Of the patients diagnosed with PVD on preoperative OCT, 50% (15/30) showed positive TA staining intraoperatively. The sensitivity of preoperative OCT assessment was 83.3%, and its specificity was 65.9%. Conclusion Preoperative OCT imaging is associated with lower sensitivity and specificity for diagnosing PVD when compared to intraoperative TA staining.

Abstract
Vaccination plays a key role in the prevention of the infectious diseases, which the armed forces are exposed to during overseas deployments. Historically, the French military health service have always contributed greatly to progress in vaccination. The military immunization schedule has often been used as a model for the national schedule. It is a powerful tool, which is constantly evolving to take into account the risks of infection inherent in deployment and to include new scientific data, while still remaining aware of the limitations of vaccination from an individual and collective standpoint. In the current context of increasingly fast emergence or re-emergence of pathogens with a high epidemic potential, developing preventive medical measures is more necessary than ever before, and the French military health service is actively participating.

Abstract
The purpose of the study is to report a case of peripheral exudative hemorrhagic chorioretinopathy (PEHCR), managed surgically with favorable visual outcome. A 66-year-old female presented with painless visual loss due to dense vitreous and subretinal hemorrhage extending from the far periphery to the macula. Pars plana vitrectomy (PPV) with subretinal tissue plasminogen activator (TPA) injection was performed resulting in good anatomical and visual outcome. PEHCR can present with severe visual loss. Surgical management with PPV and subretinal TPA injection might result in favorable anatomical and visual outcome.

Abstract
PURPOSE To determine the incidence of endophthalmitis after pars plana vitrectomy (PPV), organisms' profile, and management outcomes at a tertiary eye hospital in a Middle East country. METHODS In this single-arm cohort study conducted in 2020, medical records of patients who underwent PPV not accompanied by any other intraocular surgery were reviewed; those with a diagnosis of acute endophthalmitis in the immediate postoperative period (within 6 weeks) during the past 6 years were analyzed. RESULTS A total of 8153 records of PPV surgeries were reviewed. Five cases had endophthalmitis post-PPV with an incidence of 0.061%. Three (0.037%) had positive cultures, all of them for Staphylococcus epidermidis. The interval between PPV and diagnosis of endophthalmitis ranged from 3 to 25 days (mean, 15.8 days). Final vision after treatment ranged from 20/400 to no light perception, and one eye was eviscerated. CONCLUSION The incidence of endophthalmitis post PPV is low. Despite prompt diagnosis and standard management, visual prognosis seems to be poor. The infective agents for endophthalmitis were commensals from the ocular surface.

Abstract
BACKGROUND Patients with interstitial lung disease (ILD) are known to have diminished exercise ability. This study aimed to explore the relationship between nutrition status and body composition parameters with exercise capacity in ILD patients. A second aim focused on assessing the appropriateness of surrogate markers of nutrition status in ILD patients. METHODS Disease severity was determined by the percentage of predicted forced vital capacity. Exercise capacity was determined using 6-minute walk distance. Nutrition status was assessed using the subjective global assessment (SGA), standardized phase angle (SPhA), and impedance ratio z-score (z-IR). Bioelectrical impedance analysis estimated body composition parameters. RESULTS 45 of 79 participants (57%) were malnourished according to the SGA. FFM index z-score (z-FFMI) (r = 0.42, P = .02) and SGA (r = 0.49, P < .01) were significant predictors of exercise capacity independent of disease severity. Age (odds ratio [OR] = 1.1; 95% CI, 1.01-1.25; P = .04), low body mass index (OR = 0.73; 95% CI, 0.57-0.92; P = .01), z-FFMI (OR = 0.34; 95% CI, 0.17-0.68; P < .01), and body fat mass index z-score (OR = 0.39; 95% CI, 0.17-0.91; P = .03) were significantly associated with severe malnutrition. There was no significant difference in SPhA across SGA groups; however, a higher z-IR (poorer cell health) significantly increased the odds of severe malnutrition (OR = 2.75; 95% CI, 1.27-6.03; P = .02). CONCLUSION In ILD patients, malnutrition and loss of FFM negatively impact the ability to perform activities of daily living.

Abstract
BACKGROUND Literature focusing on nutritional variables and survival in interstitial lung disease (ILD) is limited by its focus on weight and BMI and has not considered body composition. OBJECTIVES The primary objective of this study was to examine whether body composition measures, specifically fat-free mass index z-score (z-FFMI) and body fat mass index z-score (z-BFMI), were predictors of survival in fibrotic ILD patients. The second objective was to examine if nutrition status was a predictor of survival. METHOD Seventy-eight outpatients diagnosed with fibrotic ILD were recruited in this cross-sectional study. Body composition data using dual frequency bioelectrical impedance analysis (BodyStat 1500MD; UK) and nutrition status using the subjective global assessment (SGA) were determined. To control for age and sex, z-FFMI and z-BFMI were calculated using population means. Participant charts were reviewed for diagnosis, age, disease severity, and exercise capacity. RESULTS Age (HR 1.08, 95% CI [1.03-1.13], p < 0.01), BMI (HR 0.90, 95% CI [0.84-0.97], p < 0.01]), z-FFMI (HR 0.70, 95% CI [0.56-0.87], p = 0.02), z-BFMI (HR 0.74, 95% CI [0.57-0.96], p < 0.01), 6-min walk distance (6MWD) (HR 0.99, 95% CI [0.99-1.00], p < 0.01), percent predicted diffusing capacity for carbon monoxide (%DLco) (HR 0.93, 95% CI [0.89-0.97], p < 0.01), and severe malnutrition (SGA-C) (HR 6.98, 95% CI [2.00-24.27], p < 0.01) were significant predictors of survival. When controlled for exercise capacity and disease severity, z-FFMI and severe malnutrition were significant predictors of survival independent of %DLco. CONCLUSION z-FFMI and severe malnutrition were significant predictors of survival in fibrotic ILD patients independent of disease severity.

Abstract
OBJECTIVE We examined the incidence and natural history of macular retinochoroidal neovascularization (RCN) in enhanced S-cone syndrome (ESCS). DESIGN Retrospective case series. METHODS This single-center study included 14 of 93 patients with ESCS who had signs of active or inactive RCN in ≥1 eye. We conducted multimodal retinal imaging, full-field electroretinography, and molecular genetic analysis of NR2E3 gene. Our main outcome measures included the cumulative incidence of RCN in ESCS, type of RCN, and mode of evolution of RCN. RESULTS Fourteen (15.1%) of 93 patients with ESCS had RCN in ≥1 eye at 2 to 27 years of age. All 22 RCNs (21 eyes of 14 patients) were macular. Twelve of the RCNs were active with exudates/hemorrhages. Of these, 5 appeared de novo in a subretinal location, with photographic evidence of no pre-existing lesions. The latter were compatible with type 3 neovascularization or retinal angiomatous proliferation and subsequently evolved into unifocal fibrotic nodules. The remaining active lesions all had some degree of pre-existing fibrosis and remained stable. Ten inactive fibrotic nodules, identical to end-stage de novo lesions, were found and were presumed to represent healed RCNs. CONCLUSIONS RCN, a treatable condition, may occur as early as 2 years of age and may be much more common in patients with ESCS than previously estimated. It may be the primary cause of the unifocal submacular fibrosis that is commonly observed in this condition. Additional research is needed to establish the pathogenesis of RCN in patients with ESCS and its optimal management.

Abstract
Tobacco worker's lung (TWL) is a type of hypersensitivity pneumonitis (HP) affecting workers exposed to tobacco leaves and molds in the humidified environment of the tobacco production industry. Limited epidemiological data point to a prevalence of TWL that is not negligible and probably underestimated. As in other types of HP, an acute vs. chronic presentation depends on the pattern of the exposure. Therefore, the clinical presentation can vary from an acute influenza-like syndrome, mostly self-limiting with the removal of the exposure, to an insidious onset of cough, exertional dyspnea, fatigue and weight loss in chronic presentations, where fibrotic changes may be observed. The main treatment strategy is the removal of the exposure to tobacco dust and molds, while the main aim of corticosteroid therapy is to reduce morbidity and prevent complications, namely the development of pulmonary fibrosis and permanent lung dysfunction. Despite the fact that TWL is quite well described, preventive measures are not usually adopted in the tobacco production industry. We present here a state of the art review of this neglected, preventable, but still prevalent and occupational-related subtype of HP.

Abstract
BACKGROUND The choice of immunosuppressive therapy in interstitial lung disease (ILD) other than idiopathic pulmonary fibrosis (IPF) is based on safety profile and expected efficacy. Azathioprine is one of the most commonly used agents to treat ILD. The immunosuppressive effect and pancreatitis risk of azathioprine are influenced by the activity of the enzyme thiopurine methyltransferase (TPMT) and by the genetic mutations in HLA-DQA1-HLA-DRB locus, respectively. We hypothesized that systematic genotyping prior to starting azathioprine improves the rate of discontinuation of immunosuppressive therapy and the total incidence of adverse drug reactions (ADRs). METHODS Eighty-two patients with ILD other than IPF were included in the study. The rate of immunosuppressive therapy discontinuation due to major ADRs and the total incidence of ADRs were compared between a cohort of genotyped patients (n = 49) and an untested cohort of patients (n = 33). RESULTS Thirty-seven out of 49 patients in the genotyped cohort and 27 out of 33 patients in the untested cohort were started on azathioprine. The rate of immunosuppressive therapy discontinuation due to major ADRs was significantly lower (6/49) in the genotyped cohort compared to the untested cohort (11/33; p = 0.0276). All but one discontinuation due to severe ADRs occurred within a month of therapy. However, the total incidence rate of ADRs was very similar in the 2 cohorts (0.025 in the genotyped cohort vs. 0.023 in the untested cohort). CONCLUSION In patients with ILD other than IPF, genotyping for azathioprine metabolism prior to starting therapy is associated with a significantly reduced rate of immunosuppressive therapy discontinuation due to major ADRs, with prevention of bone marrow suppression and pancreatitis, but without a reduction of the total incidence of ADRs. While these data support the use of genetic profiling prior to starting azathioprine to treat ILD, its cost effectiveness remains to be established.

Mura M. Use of nintedanib in interstitial lung disease other than idiopathic pulmonary fibrosis: much caution is warranted. Pulm Pharmacol Ther 2020; 66:101987. [PMID: 33387612 DOI: 10.1016/j.pupt.2020.101987] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 12/12/2020] [Accepted: 12/27/2020] [Indexed: 01/03/2023]
Abstract
Interstitial lung disease (ILD) other than idiopathic pulmonary fibrosis (IPF) is currently treated with immunosuppressive therapy, with a dynamic algorithm based on continued clinical surveillance. Published results on mycophenolate mofetil, cyclophosphamide and azathioprine showed either stabilization or improvement of lung function with these therapies. However, despite treatment optimization, progression of disease in ILD other than IPF is often observed, and a role for antifibrotic drug nintedanib has been hypothesized. The present article first reviews relevant aspects when considering anti-fibrotic therapy in progressing ILD other than IPF, including accuracy of the diagnosis, optimization of disease-modifying, immunosuppressive therapy and optimal timing. Next, a critical appraisal of published results on nintedanib in ILD other than IPF considers the design of the studies, inclusion criteria, used definition of "progression" of disease, frequency and severity of side effects observed and cost of the therapy. There currently is a strong and legitimate interest in additional therapies that can help controlling progressing ILD other than IPF. When the studies on the use of nintedanib are carefully considered, however, caution should be exercised before prematurely endorsing and applying this therapy. The conduction of studies that will clarify and justify its potential role as switch vs. add-on therapy and, at the same time, a more rigorous definition of disease progression are both strongly encouraged.

Abstract
Purpose This study evaluates a new surgical technique consisting of minimal vitreous removal under air (minimal interface vitrectomy; MIV) to reduce postoperative complications while preserving the ability to address surgical factors at the retinal break. Methods This retrospective analysis examined the outcomes of minimal interface vitrectomies in consecutive cases, with a minimum 12-month follow-up period, of primary rhegmatogenous retinal detachment (RRD), recurrent RRD after pars plana vitrectomy (PPV), or failed surgery after primary scleral buckling surgery (SBS). Results Twelve eyes of 12 patients with RRD underwent MIV. The total surgical duration was 190–300 s (mean, 245.25 s). Eight (66.7%) eyes were treated with cryotherapy, and 4 (33.3%) with endolaser to seal the retinal break. Successful, complete retinal reattachment was achieved in all eyes and maintained during follow-up. No intra- or postoperative complications occurred and no patients developed inflammation or cataract during follow-up. Conclusion and Importance We effectively removed traction and subretinal fluid and treated breaks with endolaser or cryotherapy by using a novel minimal interface vitrectomy technique in this selected population.

Abstract
BACKGROUND Adams-Oliver syndrome (AOS) is a rare, inherited multi-systemic malformation syndrome characterized by a combination of aplasia cutis congenita and transverse terminal limb defects along with variable involvement of the central nervous system, eyes, and cardiovascular system. AOS can be inherited as both autosomal-dominant and recessive traits. Pathogenic variants in the DOCK6, ARHGAP31, EOGT, RBPJ, DLL4, and NOTCH1 genes have been associated with AOS. PURPOSE To report a novel homozygous variant in the DOCK6 gene associated with Adams-Oliver syndrome type 2. MATERIALS AND METHODS Case report. RESULTS We report a case of a 4-month-old male who presented with microcephaly, global developmental delay, truncal hypotonia, and limb reduction defects. Ophthalmic examination revealed bilateral nystagmus and retinal detachment with mild cataractous changes in addition to retrolental plaque in the left eye. Next generation sequencing analysis identified a novel homozygous frameshift likely pathogenic variant (c.1269_1285dup (p.Arg429Glnfs*32)) in the DOCK6 gene. The constellation of the clinical findings and the genetic mutation were consistent with a diagnosis of AOS type 2. CONCLUSION The discovery of this new likely pathogenic variant enriches the genotypic spectrum of DOCK6 gene and contributes to genetic diagnosis and counseling of families with AOS. Neurologic and ocular findings appear to be consistent with AOS type 2 for which multidisciplinary clinical evaluation is crucial.

Abstract
Background Progression of the disease in idiopathic pulmonary fibrosis (IPF) is difficult to predict, due to its variable and heterogenous course. The relationship between radiographic progression and functional decline in IPF is unclear. We sought to confirm that a simple HRCT fibrosis visual score is a reliable predictor of mortality in IPF, when longitudinally followed; and to ascertain which pulmonary functional variables best reflect clinically significant radiographic progression. Methods One-hundred-twenty-three consecutive patients with IPF from 2 centers were followed for an average of 3 years. Longitudinal changes of HRCT fibrosis scores, forced vital capacity (FVC), total lung capacity and diffusing lung capacity for carbon monoxide were considered. HRCTs were scored by 2 chest radiologists. The primary outcome was lung transplant (LTx)-free survival after the follow-up HRCT. Results During the follow-up period, 43 deaths and 11 LTx occurred. On average, the HRCT fibrosis score increased significantly, and a longitudinal increase > 7% predicted LTx-free survival significantly, with good specificity, but limited sensitivity. The correlation between radiographic and functional progression was moderately significant. HRCT progression and FVC decline predicted LTx-free survival independently and significantly, with better sensitivity, but worse specificity for a ≥ 5% decline of FVC. However, the area under the curve towards LTx-survival were only 0.61 and 0.62, respectively. Conclusions The HRCT fibrosis visual score is a reliable and responsive tool to detect clinically meaningful disease progression. Although no individual pulmonary function test closely reflects radiographic progression, a longitudinal FVC decline improves sensitivity in the detection of clinically significant disease progression. However, the accuracy of these methods remains limited, and better prognostication models need to be found.

Abstract
BACKGROUND Epiretinal membranes (ERM) form as a result of an inward displacement of retinal structures. Removal of an ERM leads to the outward displacement of retinal vessels and visual improvement. PURPOSE The aim of the study was to evaluate the direction and extent of displacement of retinal/superficial vascular structures after a membrane peeling procedure by means of image comparison and in selected cases, a vector analysis of displacement. METHODOLOGY Scanning laser ophthalmoscope images of the retina of eyes undergoing ERM peeling were compared before and 6 months after surgery. Stratification was made between prominent and limited displacement, with assessment of visual acuity (VA), and central macular thickness (CMT). In three cases, using the optic nerve as reference, 50 landmarks were chosen within the posterior pole along large and small vascular structures allowing the construction of a vector map of displacement over 1 year. RESULTS Nine eyes with prominent and six with limited displacement were assessed. Improvement in VA was similar for both groups, while CMT drop was greatest for the worst group. Vector analysis showed that most vascular movement occurs over the first 6 months, covers most of the posterior retina, is centered around distinct nodes, and may lead to several hundred micrometers of displacement. CONCLUSIONS Superficial retinal relaxation has no direct implication on visual recovery. It originates in nodes of retinal contraction. Its extent can be significant, covering most of the posterior pole. RELEVANCE FOR PATIENTS A better understanding of retinal relaxation following the peeling of ERM may help better understand when intervention is required and which part of the membrane is critical to surgical success.

Abstract
A 56-year-old female presented with vitreous opacity with gradual visual disturbance in her right eye of 1-year duration. A Non-Hodgkin's lymphoma had been treated 15 years before. Presenting best-corrected visual acuity (BCVA) was 20/200 in her right eye and 20/25 in her left eye. Intraocular pressure was 18 mm Hg bilaterally. Slit-lamp examination revealed no abnormal findings in the anterior segment of both eyes, including the absence of cells and flare. Fundoscopic examination indicated hazy media with the typical glass-wool-like appearance in her right eye. B-scan ultrasound demonstrated that the vitreous was full of middle-echo spots, vitreous opacities, and posterior vitreous detachment occurred. The patient underwent vitreous biopsy and a standard 25-gauge pars plana vitrectomy (diagnostic and therapeutic). Intraoperatively, the eye was noted to have severe diffuse debris and very strong vitreoretinal adhesions. Cytospin smears prepared from the vitreous aspirate indicated amorphous acellular material that stained positively with Congo Red and showed apple green birefringence on polarized microscopy, consistent with the diagnosis of amyloidosis. A genetic evaluation of tongue tissue demonstrated apolipoprotein AI-derived amyloidosis. The BCVA was 20/25 OU at 3 months postoperatively.

Abstract
PURPOSE To describe the findings and the management of macular hole (MH)-related retinal detachment (RD) in children with Knobloch syndrome. DESIGN Retrospective interventional case series. PARTICIPANTS Patients with Knobloch syndrome who presented with MH-related RD. METHODS Retrospective chart review of patients with Knobloch syndrome who presented with MH-related RD from January 2012 to December 2018. Interventions included pars plana vitrectomy and silicone oil tamponade with or without scleral buckle, drainage retinotomy, or relaxing retinectomy. MAIN OUTCOME MEASURES MH characteristics and surgical anatomical outcome. RESULTS The study included 9 eyes of 5 patients (age range 2 months to 5 years; median age 5.5 months). Presenting symptoms were poor fixation and nystagmus. The fellow eye of 1 patient had RD due to peripheral breaks. The MH was clinically visible in 8 eyes and detected only by OCT in 1 eye. The RD was shallow and extended to the anterior equator in 7 eyes and localized to a punched-out atrophic lesion in 1 eye. Seven eyes underwent surgical repair. At the last follow-up examination (follow-up range 11 to 42 months; mean 24 months, standard deviation 11.8 months), retinal reattachment with MH closure was achieved in 5 eyes along with marked improvement in fixation. CONCLUSION Patients with Knobloch syndrome may develop MH-related RD as early as infancy. The condition may be easily overlooked in children but should be suspected in the setting of high myopia, vitreoretinal degeneration, and encephalocele.
