SUPRACHOROIDAL SPACE INJECTION TECHNIQUE: Expert Panel Guidance.

PURPOSE: To develop professional guidelines for best practices for suprachoroidal space (SCS) injection, an innovative technique for retinal therapeutic delivery, based on current published evidence and clinical experience. METHODS: A panel of expert ophthalmologists reviewed current published evidence and clinical experience during a live working group meeting to define points of consensus and key clinical considerations to inform the development of guidelines for in-office SCS injection. RESULTS: Core consensus guidelines for in-office SCS injection were reached and reported by the expert panel. Current clinical evidence and physician experience supported SCS injection as a safe and effective method for delivering retinal and choroidal therapeutics. The panel established consensus on the rationale for SCS injection, including potential benefits relative to other intraocular delivery methods and current best practices in patient preparation, pre- and peri-injection management, SCS-specific injection techniques, and postinjection management and follow-up. CONCLUSION: These expert panel guidelines may support and promote standardization of SCS injection technique, with the goal of optimizing patient safety and outcomes. Some aspects of the procedure may reasonably be modified based on the clinical setting and physician judgment, as well as additional study.

Alternative career paths for ophthalmologists.

PURPOSE: Traditionally, ophthalmologists complete training and then choose a clinical care setting. The skills required to become an ophthalmologist can be applied to a variety of alternative career paths within and beyond healthcare. Not unexpectedly, therefore, there is a growing trend for ophthalmologists to explore alternative career paths in both healthcare and the life science industry more broadly. In this invited editorial, we summarize the more commonly considered 'alternative career paths,' and provide personal perspectives that have helped us and others when weighing such options. RECENT FINDINGS: Prior to pursuing an alternative career path, it is important to reflect on one's motivations and goals. A number of alternative careers paths are available, and the choice of when and what to pursue is both personal and personalizable. While it can be difficult to know a priori whether and to what extent a given path will be both enjoyable and rewarding, insights and advice from those who have walked that path before you can be invaluable. We review the more common paths of administrative leadership, entrepreneurship and innovation, product development, healthcare policy, nonprofit organizations, and investing, noting that these are just examples of the many options currently available. SUMMARY: Ophthalmologists should feel empowered to design a career that is both purposeful and personally meaningful, as this will result ultimately in the greatest happiness and fulfillment. There is a world of opportunity available to those who are willing to explore and create their own path.

THE CHRYSANTHEMUM PHENOTYPE OF IDIOPATHIC MULTIFOCAL CHOROIDITIS.

PURPOSE: To describe the clinical characteristics and multimodal imaging features of a distinctive subtype of active idiopathic multifocal choroiditis (iMFC) lesions with grey-yellow chorioretinal lesions surrounded by smaller satellite dots, a presentation referred to as "chrysanthemum lesions." METHODS: Retrospective, observational, multicenter case series of eyes with active iMFC and chrysanthemum lesions. Multimodal imaging features were reviewed and presented. RESULTS: Twenty-five eyes from 20 patients (12 women and 8 men), with a mean age of 35.8 ± 17.0 years (range, 7-78 years) were included. Chrysanthemum lesions were equally located in the macula (48.0%) or the mid/far periphery (52.0%). The number of lesions per eye varied from 1 (16.0%) to more than 20 (56.0%). On optical coherence tomography, chrysanthemum lesions showed typical features of iMFC, including subretinal hyperreflective material splitting the retinal pigment epithelium/Bruch membrane. Chrysanthemum lesions were hypoautofluorescent on fundus autofluorescence imaging, hyperfluorescent on fluorescein angiography, hypofluorescent on indocyanine green angiography, and associated with choriocapillaris flow signal deficit on optical coherence tomography angiography. CONCLUSION: Active iMFC may present with findings resembling chrysanthemum lesions. The distinctive lesion morphology on ophthalmoscopic examination, the large number of lesions, and the high prevalence of exclusive midperipheral and far peripheral involvement may represent a distinctive phenotype of iMFC.

IDIOPATHIC MULTIFOCAL CHOROIDITIS WITH SERPIGINOUS-LIKE PERIPAPILLARY CHORIORETINAL ATROPHY.

PURPOSE: To report nine cases of multifocal choroiditis with serpiginous-like peripapillary chorioretinal atrophy. METHODS: A retrospective observational case series of eyes with multifocal choroiditis with serpiginous-like peripapillary chorioretinal atrophy. Multimodal imaging findings were reviewed and presented. RESULTS: Fifteen eyes of 9 patients (6 women and 3 men), with a mean age of 48.1 years (median, 46 years; range, 23-74 years), presented with multifocal choroiditis serpiginous-like peripapillary chorioretinal atrophy. All 15 eyes presented with serpiginoid peripapillary changes and had discrete patches of atrophy or punched-out scars in the posterior pole or periphery. Eleven eyes (73.3%) had cone-shaped retinal pigment epithelium elevations on optical coherence tomography, 10 eyes (66.7%) had mild vitritis, and 4 eyes (26.7%) had peripheral curvilinear streak lesions. Three eyes (20%) had choroidal neovascularization. All patients responded well to treatment with systemic immunosuppression, local corticosteroid injections, and/or intravitreal anti-vascular endothelial growth factor injections. CONCLUSION: Multifocal choroiditis may present with peripapillary chorioretinal changes resembling a serpiginous-like choroiditis in addition to the classic findings of patches of atrophy or punched-out scars in the posterior pole or periphery, cone-shaped retinal pigment epithelium elevated on optical coherence tomography and peripheral curvilinear streak lesions.

PREVALENCE AND CHARACTERISTICS OF MULTIFOCAL CHOROIDITIS/PUNCTATE INNER CHOROIDOPATHY IN PATHOLOGIC MYOPIA EYES WITH PATCHY ATROPHY.

PURPOSE: To determine the prevalence and characteristics of multifocal choroiditis/punctate inner choroidopathy (MFC/PIC) in eyes with patchy atrophy because of pathologic myopia. METHODS: Five hundred eyes of 253 patients with patchy atrophy were examined between 2014 and 2020 at the Advanced Clinical Center for Myopia. The main outcome measures included the prevalence and characteristics of active MFC/PIC lesions diagnosed by optical coherence tomography. RESULTS: Fifty-five of the 500 eyes (11%) diagnosed with patchy atrophy had optical coherence tomography features of active MFC/PIC lesions, such as focal elevations of the retinal pigment epithelium filled with medium hyperreflectivity material, curvilinear scars (Schlaegel lines), and/or areas of outer retinal atrophy. At the time when the MFC/PIC was diagnosed, the mean age was 57.3 ± 12.0 years, and the mean axial length was 29.2 ± 1.8 mm. Macular neovascularization was found in 45 of eyes (81.8%) with MFC/PIC versus 151 eyes without such findings (33.9%; P < 0.001). In 25 of the 55 eyes (45.5%), active MFC/PIC lesions were found before the development of the patchy atrophy. The Bruch membrane defects were colocated with these lesions. CONCLUSION: Active MFC/PIC lesions were identified in a minority of eyes with pathologic myopia, and a subset of these lesions were observed to progress to findings indistinguishable from myopic patchy atrophy. Evidence of MFC/PIC in eyes with pathologic myopia appeared to be a risk factor for the development of macular neovascularization.

FINGERPRINT SIGN OF THE HENLE FIBER LAYER.

PURPOSE: To describe the appearance of concentric, fingerprint-like waves within the Henle fiber layer (HFL) using en face optical coherence tomography in patients with tractional pathologies of the retina. METHODS: Retrospective analysis of six eyes of six patients imaged by optical coherence tomography with volumetric slabs positioned at the level of the HFL. RESULTS: Optical coherence tomography data from six patients with tractional vitreoretinal pathology were reviewed. Concentric, fingerprint-like microwaves were visualized through en face optical coherence tomography in all six study eyes at the level of the HFL. This finding resembled the finding of HFL waves previously noted histopathologically from force exerted on this layer. CONCLUSION: In retinal pathologies in which specific physical forces act on the retina, volumetric optical coherence tomography may permit visualization of en face concentric, fingerprint-like hyperreflective rings within the HFL. This "fingerprint sign" may represent a biomechanical consequence of traction on the retina and allow clinical decision making based on improved recognition of the existence of such traction.

Drug-induced uveitis.

PURPOSE OF REVIEW: Nearly one-half of all uveitis cases seen at tertiary referral centers have no identifiable cause. Many systemic, paraocular, intraocular, topical medications, and even vaccines can induce intraocular inflammation, scleritis, and rarely orbititis and are often overlooked as causes of uveitis. This review was undertaken to elucidate the strength of association of these medications with uveitis and to make clinicians aware of these associations, especially among newer medications. RECENT FINDINGS: Medication-induced uveitis has become particularly important and more frequently seen because of the advent of biologic therapies such as immune checkpoint inhibitors (ICPIs), BRAF, and MEK inhibitors, antivascular endothelial growth factor agents, and antitumor necrosis factor agents, as well as newer systemic bisphosphonates are strongly associated with uveitis. SUMMARY: The ever-broadening scope of pharmaceuticals now available to treat previously untreatable conditions, such as advanced metastatic cutaneous melanoma, have resulted in unintended ocular inflammatory diseases. Ophthalmologists must recognize that drugs such as ICPIs, BRAF, and MEK inhibitors, anti-vascular endothelial growth factor agents, tumor necrosis factor-α inhibitors, cidofovir, bisphosphonates, topical prostaglandin analogues, topical brimonidine, BCG vaccination can cause of uveitis. Utilizing a thorough review of systems, physicians may readily identify medications that may cause uveitis and avoid expensive and unnecessary laboratory testing.

EXPANDED CLINICAL SPECTRUM OF MULTIPLE EVANESCENT WHITE DOT SYNDROME WITH MULTIMODAL IMAGING.

PURPOSE: To evaluate and characterize multiple evanescent white dot syndrome abnormalities with modern multimodal imaging modalities. METHODS: This retrospective cohort study evaluated fundus photography, fluorescein angiography, indocyanine green angiography, optical coherence tomography, enhanced depth imaging optical coherence tomography, short-wavelength autofluorescence, and near-infrared autofluorescence. RESULTS: Thirty-four multiple evanescent white dot syndrome patients with mean age of 28.7 years were studied (range, 14-49 years). Twenty-six patients were women, and eight were men. Initial mean visual acuity was 0.41 logMAR. Final mean visual acuity was 0.03 logMAR. Fluorescein angiography shows a variable number of mid retinal early fluorescent dots distributed in a wreathlike pattern, which correlate to fundus photography, fundus autofluorescence, and indocyanine green angiography. Indocyanine green angiography imaging shows the dots and also hypofluorescent, deeper, and larger spots, which are occasionally confluent, demonstrating a large plaque of deep retinal hypofluorescence. Optical coherence tomography imaging shows multifocal debris centered at and around the ellipsoid layer, corresponding to the location of spots seen with photography, indocyanine green angiography, and fluorescein angiography. Protrusions of the hyperreflectant material from the ellipsoid layer toward the outer nuclear layer correspond to the location of dots seen with photography, indocyanine green angiography, and fluorescein angiography. CONCLUSION: Multimodal imaging analysis of the retina in patients with multiple evanescent white dot syndrome shows additional features that may help in the diagnosis of the disease and in further understanding its etiology. Multiple evanescent white dot syndrome is predominantly a disease of the outer retina, centered at the ellipsoid zone, but also involving the interdigitation zone and the outer nuclear layer.

Idiopathic Orbital Inflammation Associated With Necrotizing Scleritis and Temporal Bone Inflammation.

The authors present a case of aggressive idiopathic orbital inflammation producing necrotizing scleritis along with synchronous tumefactive fibroinflammatory lesion of the temporal bone. A young woman with no medical history presented with sectoral scleritis and mildly reduced vision. Response to initial treatment, which included topical and systemic corticosteroids, as well as systemic nonsteroidal anti-inflammatory drugs, was limited. Over the following months, signs of orbital inflammation developed, including ptosis, proptosis, and limited extraocular motility. MRI revealed both orbital and ipsilateral temporal bone masses. An orbital biopsy was performed revealing a mixed inflammatory infiltrate, whereas a biopsy of the temporal bone mass revealed a tumefactive fibroinflammatory lesion. Biopsy showed no histopathologic evidence of infection nor neoplasm. The patient eventually responded to treatment with systemic prednisone, azathioprine, and rituximab.

Idiopathic multifocal choroiditis with outer retinal or chorioretinal atrophy.

PURPOSE: To report thirteen cases of idiopathic multifocal choroiditis with discrete chorioretinal lesions who were found to have zonal, multizonal, or diffuse outer retinal or chorioretinal atrophy. METHODS: A retrospective observational case series using multimodal imaging including high-definition optical coherence tomography, fundus autofluorescence imaging, and fluorescein and indocyanine green angiography. RESULTS: Twenty-one eyes in 13 patients with idiopathic multifocal choroiditis were found to have zonal, multizonal, or diffuse outer retinal or chorioretinal atrophy visualized using multimodal imaging. Thirteen eyes presented with diffuse disease, six eyes with multizonal, and two with zonal atrophy. Patterns of atrophy included zones surrounding the optic nerve, multiple geographic zones in the mid and far periphery, and a diffuse peripheral pattern with relative sparing of the central macula until later in the course of disease. Eleven of the 13 patients were treated with topical, periocular, or systemic corticosteroids, and 1 patient was also treated with systemic immunomodulatory treatment. The atrophic changes progressed over an average of 8 years of follow-up in 10 eyes despite therapy. CONCLUSION: Idiopathic multifocal choroiditis can present with an uncommon pattern of zonal, multizonal, or diffuse outer retinal or chorioretinal atrophy as part of its clinical spectrum. The severity, extent, and progression of these atrophic changes are best appreciated using multimodal diagnostic imaging.

Sensitivity of fluid detection in patients with neovascular amd using spectral domain optical coherence tomography high-definition line scans.

PURPOSE: To determine the sensitivity of the Cirrus high-definition (HD) 5-line raster scans for detecting retinal fluid in neovascular age-related macular degeneration when using the spectral domain optical coherence tomography macular cubes as a gold standard. METHODS: Patients were retrospectively identified from their initial follow-up visit after being newly diagnosed with neovascular age-related macular degeneration in at least one eye. Patients were imaged with Cirrus spectral domain optical coherence tomography using the 512 × 128 macular cube scan and HD 5-line raster scan settings. Patients with other diseases that cause subretinal or intraretinal fluid, or who had an epiretinal membrane causing macular traction were excluded from the analysis. We recorded the presence or absence of subretinal or intraretinal fluid in the macular cube and on the HD 5-line raster scans. RESULTS: Seventy-nine patients met the study requirements. Of the 63 patients who had fluid present on the macular cube, 1 did not seem to have fluid on the HD 5-line raster scans. Taking the macular cube as a gold standard, the sensitivity of the HD 5-line raster scans for detecting retinal fluid in this cohort was 98.4%. CONCLUSION: The Cirrus HD 5-line raster scans have a high sensitivity for detecting fluid in the macular cube in patients with neovascular age-related macular degeneration.

En face spectral domain optical coherence tomography analysis of lamellar macular holes.

PURPOSE: To analyze the anatomical characteristics of lamellar macular holes using cross-sectional and en face spectral domain optical coherence tomography. METHODS: Forty-two lamellar macular holes were retrospectively identified for analysis. The location, cross-sectional length, and area of lamellar holes were measured using B-scans and en face imaging. The presence of photoreceptor inner segment/outer segment disruption and the presence or absence of epiretinal membrane formation were recorded. RESULTS: Forty-two lamellar macular holes were identified. Intraretinal splitting occurred within the outer plexiform layer in 97.6% of eyes. The area of intraretinal splitting in lamellar holes did not correlate with visual acuity. Eyes with inner segment/outer segment disruption had significantly worse mean logMAR visual acuity (0.363 ± 0.169; Snellen = 20/46) than in eyes without inner segment/outer segment disruption (0.203 ± 0.124; Snellen = 20/32) (analysis of variance, P = 0.004). Epiretinal membrane was present in 34 of 42 eyes (81.0%). CONCLUSION: En face imaging allowed for consistent detection and quantification of intraretinal splitting within the outer plexiform layer in patients with lamellar macular holes, supporting the notion that an area of anatomical weakness exists within Henle's fiber layer, presumably at the synaptic connection of these fibers within the outer plexiform layer. However, the en face area of intraretinal splitting did not correlate with visual acuity, disruption of the inner segment/outer segment junction was associated with significantly worse visual acuity in patients with lamellar macular holes.

Multifocal choroiditis without panuveitis: clinical characteristics and progression.

PURPOSE: To describe the clinical characteristics and progression of patients with multifocal choroiditis lesions who had minimal or no evidence of anterior uveitis and/or vitritis. METHODS: Retrospective, observational, single-center consecutive case series. Clinical histories, examination, and multimodal imaging findings were analyzed. RESULTS: Sixty-five eyes of 41 patients were identified. The mean age at diagnosis was 38.4 years (median, 35 years; range, 15-81 years), and 70.7% of the patients were women. Involvement was bilateral in 21 patients (51.2%) at presentation. The 60-month bilateral event-free survival was 75.0% (95% confidence interval, 49.8-91.2%). The mean visual acuity was 20/46 (median, 20/25; range, 20/20 to count fingers at 2 feet) at presentation and 20/42 (median, 20/25; range, 20/20-5/400) at the last recorded visit. The 60-month "20/50 or worse" event-free survival was 100%. Between the first presentation and final follow-up (a mean duration of 92.6 months; range, 0-343 months), 46.7% of the eyes developed new or larger chorioretinal spots and 32.6% developed new or recurrent choroidal neovascularization. The 60-month choroidal neovascularization event-free survival was 68.1% (95% confidence interval, 39.2-85.4%). CONCLUSION: Patients with multifocal choroiditis lesions, but with minimal or no anterior uveitis or vitritis, tended to be young women. Approximately half of the patients presented with bilateral involvement, which is less than has been reported in most case series of multifocal choroiditis with panuveitis. One quarter of all unilaterally affected patients will develop bilateral involvement by 60 months.

Spectral domain optical coherence tomography findings in patients with acute syphilitic posterior placoid chorioretinopathy.

PURPOSE: To describe the appearance of acute syphilitic posterior placoid chorioretinitis, a rare ocular manifestation of syphilis, on spectral domain optical coherence tomography (SD OCT) both before and after treatment. METHODS: Ophthalmic examination and imaging studies of 30 eyes of 19 confirmed cases were analyzed both at the time of presentation and at each follow-up visit. Patients with SD OCT and fluorescein angiography at the time of presentation, and at least three documented follow-up visits after initiation of therapy, were included in the study. Standard treatment of neurosyphilis was given to each patient, including 4 million units of penicillin G administered intravenously every 4 hours for 14 days. RESULTS: Fundus examination and imaging studies were consistent with previous reports and confirmed the diagnosis of acute syphilitic posterior placoid chorioretinitis. In 13 eyes (43.3%), baseline SD OCT scans were performed within 1 to 2 days of presentation and revealed a small amount of subretinal fluid, disruption of the inner segment/outer segment junction, and hyperreflective thickening of the retinal pigment epithelium (RPE). All 30 eyes were again scanned between Days 7 and 9 after presentation and revealed loss of the inner segment/outer segment and OS/RPE bands, and irregular hyperreflectivity of the RPE with prominent nodular elevations but without subretinal fluid. Early disruption of the external limiting membrane and punctate choroidal hyperreflectivity were seen in 1 of the 30 eyes (3.3%) and 14 of the 30 eyes (46.6%), respectively. Vision improved and the outer retinal abnormalities normalized in 28 of the 30 eyes (93.3%) after the treatment of neurosyphilis. The external limiting membrane, inner segment/outer segment band, and/or linear outer segment/RPE junction remained substantially abnormal despite treatment in 2 eyes left with 20/200 vision. CONCLUSION: Patients with acute syphilitic posterior placoid chorioretinitis show characteristic outer retinal abnormalities on SD OCT imaging, including disruption of the inner segment/outer segment band, nodular thickening of the RPE with loss of the linear outer segment/RPE junction, and, in some cases, loss of the external limiting membrane, accumulation of subretinal fluid, and punctate hyperreflectivity in the choroid. Vision improved and these abnormalities reversed after treatment of neurosyphilis in most of the patients. Persistently, poor vision despite treatment was associated with long-term loss or disruption of outer retinal anatomy on SD OCT.

Intravitreal injection technique and monitoring: updated guidelines of an expert panel.

PURPOSE: To review evidence and provide updated guidelines on intravitreal (IVT) injection technique and monitoring. METHODS: A review of the published literature on IVT injection from 2004 to 2014 formed the basis for round table deliberations by an expert panel of ophthalmologists. RESULTS: The dramatic increase in the number of IVT injections has been accompanied by a comparable increase in evidence surrounding IVT practice patterns and techniques. The expert panel identified a number of areas that have evolved since publication of the original IVT injection guidelines in 2004, the most notable of which were a lack of evidence to support the routine use of pre-, peri-, and postinjection antibiotics to reduce the risk of endophthalmitis, and the role of aerosolized droplets containing oral contaminants from the patient and/or providers as a potential source of infection. The panel emphasized the continued importance of applying povidone-iodine to and avoiding eyelid contact with the intended injection site and needle. CONCLUSION: Updated guidelines on IVT injection technique and monitoring are proposed based on a review of published literature and expert panel deliberations.

Knowledge and Current Practices in Monogenic Uveitis: An International Survey by IUSG and AIDA Network.

INTRODUCTION: This study aims to explore awareness, knowledge, and diagnostic/therapeutic practices in monogenic uveitis (mU) among uveitis experts. METHODS: This is an explorative, cross-sectional survey study. An anonymous, semi-structured, electronic survey was delivered to uveitis experts from the Autoinflammatory Diseases Alliance (AIDA) Network and International Uveitis Study Group (IUSG). We included respondents answering ≥ 50% of the survey. RESULTS: Seventy-seven participants rated their knowledge of mU as proficient (3.9%), adequate (15.6%), sufficient (16.9%), or poor (63.6%). When asked about the first mU gene they thought of, 60.4% mentioned NOD2, 3.9% mentioned NLRP3 or MEFV, and 49.4% provided incorrect or no answers. Success rates in clinical scenarios varied from 15.6% to 55.8% and were higher for ophthalmologists working in multidisciplinary teams (p < 0.01). Genetic testing was ordered for suspected mU by 41.6% of physicians. The availability of molecular techniques did not significantly differ based on geography (p > 0.05). The public healthcare system ensured a higher percentage of tests prescribed were obtained by patients compared to private insurances (p < 0.00). In terms of disease-modifying anti-rheumatic drugs (DMARDs), tumor necrosis factor-α inhibitors were the most familiar to uveitis experts. The difficulties with off-label therapy procedures were the primary barrier to DMARDs prescription for patients with mU and correlated inversely with the obtained/prescribed drug ratio for interleukin-1 (p < 0.01) and interleukin-6 (p < 0.01) inhibitors. CONCLUSIONS: This survey identifies proficiency areas, gaps, and opportunities for targeted improvements in patients care. The comprehensive outputs may inform evidence-based guidelines, empowering clinicians with standardized approaches, and drive an AIDA Network-IUSG unified effort to advance scientific knowledge and clinical practice.

Drug-induced uveitis.

PURPOSE OF REVIEW: Although more than 50% of all uveitis cases have no identifiable cause, certain medications can cause ocular inflammation and are often overlooked. Drug-induced ocular inflammation has increased in frequency with the advent of new bisphosphonates, antitumor necrosis factor biologic agents, and intravitreal triamcinolone and antivascular endothelial growth factor medications. Identification of these inciting drugs will simplify work-up and management of patients with uveitis and improve visual outcomes. RECENT FINDINGS: This review briefly focuses on the drugs that have long been known to be strongly associated with uveitis and emphasize new observations about these associations. It will also highlight the newest medications associated with uveitis and scleritis. The strength of the association between each drug and uveitis will be quantified and categorized into definite, probable, possible, and unlikely causes of uveitis utilizing Naranjo's classification criteria. SUMMARY: Drug-induced uveitis has become increasingly recognized in association with a number of commonly used systemic, intraocular, and topical medications. A detailed history is often all that is needed to identify these important, often overlooked, and readily curable causes of uveitis. Most cases of drug-induced uveitis respond promptly to discontinuation of the suspected agent in conjunction with topical corticosteroid and cycloplegic therapy.
