RESUMO

PURPOSE: An independent Safety Review Committee (SRC), supported by Novartis Pharma AG, analyzed investigator-reported cases of intraocular inflammation (IOI), endophthalmitis, and retinal arterial occlusion in the phase 3 HAWK and HARRIER trials of brolucizumab versus aflibercept in neovascular age-related macular degeneration (nAMD). DESIGN: A post hoc analysis of a subset of data from two 2-year, double-masked, multicenter, active-controlled randomized phase 3 trials (NCT02307682, NCT02434328). PARTICIPANTS: Patients (N = 1817) with untreated, active choroidal neovascularization due to age-related macular degeneration in the study eye were randomized and treated in HAWK/HARRIER. The SRC reviewed data from cases of investigator-reported IOI (60/1088 brolucizumab-treated eyes; 8/729 aflibercept-treated eyes). METHODS: The SRC received details and images (color fundus photography, fluorescein angiography, and OCT) for all investigator-determined cases of IOI, retinal arterial occlusion, and endophthalmitis. Cases were reviewed in detail by ≥2 readers, then adjudicated by the SRC as a group. MAIN OUTCOME MEASURES: Within this patient subset: incidence of IOI, signs and incidence of retinal vasculitis and/or retinal vascular occlusion, and visual acuity loss; time since first brolucizumab injection to IOI event onset; and frequency of visual acuity loss after brolucizumab injection by time of first IOI event onset. RESULTS: Fifty brolucizumab-treated eyes were considered to have definite/probable drug-related events within the spectrum of IOI, retinal vasculitis, and/or vascular occlusion. On the basis of these cases, incidence of definite/probable IOI was 4.6% (IOI + vasculitis, 3.3%; IOI + vasculitis + occlusion, 2.1%). There were 8 cases (incidence 0.74%) of at least moderate visual acuity loss (≥15 ETDRS letters) in eyes with IOI (7 in eyes with IOI + vasculitis + occlusion). Of the 8 cases, 5 experienced their first IOI-related event within 3 months of the first brolucizumab injection (increasing to 7/8 within 6 months). Incidence of IOI in aflibercept-treated eyes was 1.1%, with at least moderate visual acuity loss in 0.14%. CONCLUSIONS: This analysis of IOI cases after brolucizumab injection identified signs of retinal vasculitis with or without retinal vascular occlusion and an associated risk of visual acuity loss. The findings will help physicians to evaluate the risks and benefits of brolucizumab treatment for nAMD.

RESUMO

PURPOSE: A prior study revealed discrepancies in self-reported surgical numbers between male and female ophthalmology residents. This study further investigates the gender differences in self-reported procedural volume among vitreoretinal surgery fellows and examines the differences for surgical, medical, and total self-reported procedural volume between male and female vitreoretinal fellows. METHODS: A retrospective review of case logs submitted to the American Society of Retina Specialists by first-year and second-year vitreoretinal fellows from July 1, 2018, to June 30, 2019, was performed. Fellows who reported fewer than 100 pars plana vitrectomies were excluded. A total of 133 fellows were included. RESULTS: Overall, 37 of 57 (65%) first-year fellows and 59 of 76 (78%) second-year fellows were male. An average of 1,120 procedures were self-reported among all vitreoretinal fellows. In the group of second-year fellows at the completion of fellowship, men reported more total procedures (1,171 [864-1,600] vs. 1,005 [719-1,257]; P = 0.072). Women reported statistically significant fewer endolaser (P = 0.018), internal limiting membrane peel (P = 0.042), and cryoretinopexy (P = 0.002) procedures compared with men. When splitting the data by total surgical versus medical procedures, men reported more procedures than women both surgically (1,077 [799-1,490] vs. 925 [622-1,208]; P = 0.085) and medically (72 [41-116] vs. 56 [20-94]; P = 0.141), although these differences were not statistically significant. CONCLUSION: There is a trend for female vitreoretinal fellows to report fewer surgical procedures than their male counterparts, raising concerns for gender gaps in vitreoretinal surgical training. Further research is needed to verify this discrepancy and identify potential barriers that female vitreoretinal surgeons are facing in training.

RESUMO

SIGNIFICANCE: This case report highlights the merits of using fine needle aspiration biopsy to obtain gene expression profiling of individual choroidal melanomas when more than one tumor arises in the same eye. It is also the first such case to document laser ablation therapy as the primary treatment. PURPOSE: This report describes a case of two primary choroidal melanomas with different genetic profiles in the same eye. CASE REPORT: An 80-year-old man presented to the office with a neoplasm of uncertain behavior in the left eye. The patient's visual acuity and IOP in the left eye, respectively, at the time of his first visit to the office were 20/25 and 8 mmHg. A dilated fundus examination revealed that there were two choroidal lesions in the left eye. The macular lesion was classified as type 1A, and the ciliochoroidal lesion was classified as type 1B. The patient underwent a vitrectomy of the left eye, followed by endolaser ablation of the tumors. The patient was also injected with bevacizumab. To date, the patient is free of known metastasis. Most recently, his visual acuity and IOP in the left eye were 20/30 and 14 mmHg, respectively. CONCLUSIONS: Although rare, multiple melanomas in the same eye may have differing genetic profiles, which may alter prognosis and management, depending on the class of tumor detected.

RESUMO

SIGNIFICANCE: This study aimed to highlight the association of stellate neuroretinitis occurring secondary to endogenous candidemia. PURPOSE: We report an unusual presentation of endogenous Candida endophthalmitis as a stellate neuroretinitis in the setting of Cornelia de Lange syndrome. CASE REPORT: A 34-month-old girl with severe Cornelia de Lange syndrome and a history of parenteral nutrition dependence requiring a chronic central venous catheter presented with bilateral endophthalmitis secondary to candidemia. In one eye, the endophthalmitis had the atypical presentation as a stellate neuroretinitis. CONCLUSIONS: This case represents a unique association of stellate neuroretinitis secondary to Candida infection in a patient with Cornelia de Lange syndrome.

RESUMO

OBJECTIVE: To describe the frequency and predictors of local treatment failure and enucleation after iodine 125 (I125) brachytherapy in patients with choroidal melanoma treated and followed up in a large randomized clinical trial. DESIGN: Prospective, noncomparative, interventional case series within a randomized, multicenter clinical trial. PARTICIPANTS: Patients enrolled in the Collaborative Ocular Melanoma Study (COMS) trial of enucleation versus brachytherapy between February 1987 and July 1998; tumors measured 2.5 to 10.0 mm in apical height and no more than 16.0 mm in longest basal dimension. METHODS: I125 brachytherapy was administered via episcleral plaque according to a standard protocol. Follow-up ophthalmic evaluations, including ophthalmic ultrasound and fundus photography, were performed according to a standard protocol at baseline, every 6 months thereafter for 5 years, and subsequently at annual intervals. Survival analysis methods were used to estimate the cumulative risk of postirradiation treatment failure and enucleation. Factors associated with treatment failure and enucleation of plaqued eyes were evaluated using Cox proportional hazards analysis. MAIN OUTCOME MEASURES: Reports of enucleation and of local treatment failure, defined as tumor growth, recurrence, or extrascleral extension, derived from clinical reports based on echographic and photographic documentation. RESULTS: As of September 30, 2000, 638 of the 650 patients randomized to brachytherapy and so treated had been followed up for 1 year or longer, and 411 had been followed up for at least 5 years. Sixty-nine eyes were enucleated during the first 5 years after brachytherapy, and treatment failure was reported for 57 eyes. The Kaplan-Meier estimate of proportion of patients undergoing enucleation by 5 years was 12.5% (95% confidence interval [CI], 10.0%-15.6%); the risk of treatment failure was 10.3% (95% CI, 8.0%-13.2%). Treatment failure was the most common reason for enucleation within 3 years of treatment; beyond 3 years, ocular pain was most common. Risk factors for enucleation were greater tumor thickness, closer proximity of the posterior tumor border to the foveal avascular zone, and poorer baseline visual acuity in the affected eye. Risk factors for treatment failure were older age, greater tumor thickness, and proximity of the tumor to the foveal avascular zone. Local treatment failure was associated weakly with reduced survival after controlling for baseline tumor and personal characteristics (adjusted risk ratio, 1.5; P = 0.08). CONCLUSIONS: Local treatment failure and enucleation were relatively infrequent events after I125 brachytherapy within the COMS. Treatment failure typically occurred early and was associated weakly with poorer survival. The COMS randomized trial documented the absence of a clinically or statistically significant difference in survival for patients randomly assigned to enucleation versus brachytherapy. This analysis documents the efficacy of brachytherapy to achieve sustained local tumor control and to conserve the globe.

RESUMO

PURPOSE OF REVIEW: This review provides a historic perspective of the impact that major pandemics have had on human and their relationship with ophthalmology. The novel coronavirus epidemic is also analyzed, highlighting the relevance of the eye as a possible source of transmission, infection, and prognosis for the disease. RESULTS: Smallpox is suspected to be present for more than 12 000 years. However, trachoma seems to be the first recorded ophthalmological infectious disease. The deadliest pandemics include the bubonic plague, smallpox, and Spanish flu. The CoVID-19 epidemic is still developing and measures need to be implemented to prevent further escalation of the crisis. SUMMARY: Understanding the current facts in light of earlier historical evidence may help us prepare better to minimize the spread of infections in the future.

RESUMO

SIGNIFICANCE: The case report highlights the possible complications of undergoing neck manipulation within a critical time period after intravitreal injection. PURPOSE: This study aimed to describe a case of traumatic hemorrhagic choroidal detachment after cervical manipulation during a chiropractic treatment session. CASE REPORT: A 43-year-old male patient with a history of complex rhegmatogenous retinal detachment repair and recurrent cystoid macular edema presented with decreased vision and sudden pain in the right eye after chiropractic manipulation of the neck, status post-intravitreal injection of triamcinolone, which was performed earlier that day. Vision in the right eye was hand motion and 20/20 in the left eye. IOPs were 8 and 11 mmHg, respectively. Slit lamp examination of the right eye revealed blood-tinged steroid residues in the anterior chamber. There was no view to the posterior pole. Ultrasonography showed a lobulated mass with heterogeneous echogenicity consistent with a large hemorrhagic choroidal detachment. No central kissing was observed. Left eye examination was unremarkable. CONCLUSIONS: With the increasing use of complementary and alternative medicine, a better understanding of potential complications to raise awareness is becoming essential.

RESUMO

INTRODUCTION: The intra-arterial chemotherapy (IAC) is increasingly used as a first-line therapy for retinoblastoma. The IAC has proved to be relatively safe. However, many local side effects of IAC have been described. CASE PRESENTATION: This case report describes a local side effect presenting as proptosis and myositis with vascular access difficulty of the middle meningeal artery, in a 2-year-old male with left eye diffuse multifocal stage Vb retinoblastoma complicated with retinal detachment. DISCUSSION/CONCLUSION: IAC is assured to provide as efficient results in eliminating the tumor as the systemic chemotherapy, without causing the systemic side effects. It has become an alternative to systemic chemotherapy. A better understanding of the local side effects is required.

RESUMO

PURPOSE: Pediatric retinal detachments (RDs) are unique in etiology, anatomy, and prognosis compared with the adult population. The mechanisms of pediatric RD include tractional (TRD), rhegmatogenous retinal detachment, traumatic, and other types, such as exudative or hemorrhagic. This study examined visual and anatomical outcomes of pediatric RD undergoing surgical repair at a single university referral center. METHODS: A retrospective consecutive case series of patients clinically diagnosed and undergoing surgery for RD between birth and 15 years of age from 2002 to 2013 at a single academic institution. RESULTS: A total of 206 patients (231 eyes) were included in this study, of which 25 (12%) had bilateral RD. Of those patients, 67 (29%) had TRD (retinopathy of prematurity, persistent fetal vasculature, or familial exudative vitreoretinopathy), 51 (22%) had rhegmatogenous retinal detachment (myopia, X-linked retinoschisis, or Stickler syndrome), 60 (26%) had traumatic RD, and 53 (23%) were due to other types of RD, such as Coats disease or coloboma. Presenting best-corrected visual acuity better than 20/200 correlated with better final best-corrected visual acuity (P < 0.0001). Anatomical success was strongly correlated with visual acuity outcome (P < 0.00001) and was significantly more likely in rhegmatogenous retinal detachment versus TRD (78% vs. 39%, P < 0.05). The rates of obtaining a final best-corrected visual acuity > 20/200 were poorer in TRD (10%) compared with rhegmatogenous retinal detachment (39%, P < 0.01) or traumatic RD (28%, P < 0.05). CONCLUSION: Visual and anatomical outcomes varied among categories of RD. Rhegmatogenous retinal detachments were associated with the best outcomes (anatomical success and globe conservation), whereas TRDs generally had poorer visual and anatomical outcomes.

RESUMO

SIGNIFICANCE: This case highlights the importance of using ultrasonography to evaluate an eye that has no clear view of the fundus. PURPOSE: Uveal melanoma stems from melanocytes found in the iris, ciliary body, and choroid, and it is the most common primary intraocular malignancy found in adults. The lesion is identified predominantly via fundus biomicroscopy and binocular indirect ophthalmoscopy. The authors present a unique case where visual evaluation of the fundus was not possible, and ultrasonography was used to assess the retina and choroid. CASE REPORT: A 38-year-old Hispanic man with prior ocular trauma presented with an eye that could not be clinically examined owing to complete pupil occlusion. The diagnosis of presumed uveal melanoma was made exclusively based on the outcome of ocular ultrasonography. Further histologic, antibody, and genetic testing was completed once the patient had undergone treatment of the affected eye and uveal melanoma was confirmed. CONCLUSIONS: In this rare instance, B-scan ultrasonography provided a finding that required the patient to undergo enucleation in an eye without visual potential. Genetic testing was then used to appropriately categorize the tumor as a class 1B melanoma, indicating that there is a risk of metastasis. Consequently, the patient is being monitored by a medical oncologist.

RESUMO

PURPOSE: To determine the feasibility and safety of bilateral simultaneous vitreoretinal surgery in pediatric patients. DESIGN: International, multicenter, interventional, retrospective case series. PARTICIPANTS: Patients 17 years of age or younger from 24 centers worldwide who underwent immediate sequential bilateral vitreoretinal surgery (ISBVS)-defined as vitrectomy, scleral buckle, or lensectomy using the vitreous cutter-performed in both eyes sequentially during the same anesthesia session. METHODS: Clinical history, surgical details and indications, time under anesthesia, and intraoperative and postoperative ophthalmic and systemic adverse events were reviewed. MAIN OUTCOME MEASURES: Ocular and systemic adverse events. RESULTS: A total of 344 surgeries from 172 ISBVS procedures in 167 patients were included in the study. The mean age of the cohort was 1.3±2.6 years. Nonexclusive indications for ISBVS were rapidly progressive disease (74.6%), systemic morbidity placing the child at high anesthesia risk (76.0%), and residence remote from surgery location (30.2%). The most common diagnoses were retinopathy of prematurity (ROP; 72.7% [P < 0.01]; stage 3, 4.8%; stage 4A, 44.4%; stage 4B, 22.4%; stage 5, 26.4%), familial exudative vitreoretinopathy (7.0%), abusive head trauma (4.1%), persistent fetal vasculature (3.5%), congenital cataract (1.7%), posterior capsular opacification (1.7%), rhegmatogenous retinal detachment (1.7%), congenital X-linked retinoschisis (1.2%), Norrie disease (2.3%), and viral retinitis (1.2%). Mean surgical time was 143±59 minutes for both eyes. Higher ROP stage correlated with longer surgical time (P = 0.02). There were no reported intraoperative ocular complications. During the immediate postoperative period, 2 eyes from different patients demonstrated unilateral vitreous hemorrhage (0.6%). No cases of endophthalmitis, choroidal hemorrhage, or hypotony occurred. Mean total anesthesia time was 203±87 minutes. There were no cases of anesthesia-related death, malignant hyperthermia, anaphylaxis, or cardiac event. There was 1 case of reintubation (0.6%) and 1 case of prolonged oxygen desaturation (0.6%). Mean follow-up after surgery was 103 weeks, and anatomic success and globe salvage rates were 89.8% and 98.0%, respectively. CONCLUSIONS: This study found ISBVS to be a feasible and safe treatment paradigm for pediatric patients with bilateral vitreoretinal pathologic features when repeated general anesthesia is undesirable or impractical.

RESUMO

PURPOSE: Retinal capillary hemangioma (RCH) can occur in isolation or may be associated with von Hippel-Lindau disease. The classic RCH is described as a globular reddish lesion with a dilated feeding artery and a tortuous draining vein, indicative of a common endophytic growth pattern. Exophytic patterns are far more rare and, because of its subtle appearance, often missed or misdiagnosed. CASE REPORT: A 24-year-old woman presented with complaints of a mid-peripheral superior field defect OS. She had no family history of von Hippel-Lindau disease. Best-corrected visual acuity was 20/20 OD, OS. Dilated fundus examination of the left eye revealed a peripheral large inferotemporal retinal lesion with an overlying vascular network. Corresponding feeding and draining vasculature was not clearly noted on dilated fundus examination. Optical coherence tomography, ultrasonography, and fluorescein angiography testing were used to confirm the diagnosis of an exophytic peripheral RCH. Anti-vascular endothelial growth factor injections and cryotherapy were initiated, and the patient was scheduled for radioactive plaque brachytherapy. Genetic testing and proper scans were also recommended. CONCLUSIONS: This case illustrates an atypical exophytic peripheral RCH, rarely reported in the literature. The utilization of a variety of diagnostic modalities was highly effective, aiding in the diagnosis of this condition.

RESUMO

PURPOSE: Terson's syndrome is a condition where a preretinal hemorrhage forms as a result of increased intracranial pressure. The elevated intracranial pressure is thought to be transmitted through the veins and the optic nerve sheath to the optic disc and retina, causing the thin capillary walls to rupture. The authors present a unique case of Terson's syndrome in a patient who underwent recent surgical management for cerebellar hemangioblastomas related to von Hippel-Lindau disease. CASE REPORT: A 17-year-old African American female patient with a history of von Hippel-Lindau disease presented with pain in her right eye. She had recently undergone surgery to remove cerebellar hemangioblastomas. Preliminary fundus imaging was performed, but before formal ophthalmic testing could be conducted, the patient seized and was taken directly to the emergency room. When the patient returned for a formal evaluation 3 weeks later, a new preretinal "boat-shaped" hemorrhage was now present. Additionally, reports from the emergency room suggested that she had bled into the cavity where the previous cerebellar resection had taken place. This hemorrhage likely led to an increase in intracranial pressure, causing a Terson's-like event. CONCLUSIONS: A Terson's event may be caused by high intracranial pressure secondary to the surgical removal of von Hippel-Lindau syndrome-associated cerebellar tumors and should be included as a possible complication of surgical management.

RESUMO

PURPOSE: Presumed congenital simple hamartoma of the retinal pigment epithelium (CSHRPE) is a rare intraocular finding that is described as a focal, nodular, jet black lesion. These lesions frequently occur at or near the macula and have no known association with changes in the surrounding neurosensory retina, retinal pigment epithelium, or choroid, nor have they been related with exudation or hemorrhage. Until now, there have been no cases reported of CSHRPE with associated vascular activity. CASE REPORT: A 14-year-old Hispanic adolescent girl with a presumed CSHRPE presented with adjacent macular edema. The patient was treated with an off-label intravitreal bevacizumab injection to decrease the edema. Two months later, the patient presented with improved visual acuity and decreased macular edema. CONCLUSIONS: This is the first documented case of macular edema secondary to vascular activity being associated with these rare lesions. When CSHRPE is found to have secondary vascular activity and associated macula edema, treatment of intravitreal bevacizumab may lead to improved visual and anatomical outcomes.

RESUMO

PURPOSE: Gene expression profiling has been shown to yield two distinct molecular genetic signatures for uveal melanoma. These class designations tend to predict tumor aggressiveness and the likelihood of metastasis. Tumors with a class 1 genetic signature are generally much less aggressive than tumors with a class 2 genetic signature. Gene expression analysis for previously treated uveal melanoma has not yet been reported. The authors report three cases where genetic analysis was successfully obtained from uveal melanoma that was previously treated years earlier with radiotherapy. CASE REPORT: The patients in all three cases received globe-conserving radiotherapy for treatment of choroidal melanoma before gene expression profiling was readily available. The patients in cases 1 and 2 received 125I plaque brachytherapy while the patient in case 3 received proton irradiation therapy. When secondary surgery was necessary to stabilize these eyes from the effects of radiation retinopathy, fine-needle aspiration biopsy was also performed for gene expression profiling. Genomic analysis revealed a class 1 molecular signature for the patient in case 1 and a class 2 molecular signature for the patients in cases 2 and 3. CONCLUSIONS: Gene expression profiling for uveal melanoma may be obtained from patients who were previously treated with radiotherapy; however, the implication of these results will benefit from ongoing clinical evaluation.

RESUMO

PURPOSE: A case of a teenage girl with tapioca melanoma of the iris is presented. This case is unusual, as the patient did not have heterochromia and did not present with elevated intraocular pressure. CASE REPORT: A 14-year-old female patient presented with an amelanotic, multinodular, multifocal lesion of the right iris. Pathology confirmed a diagnosis of tapioca melanoma using immunohistologic staining. The patient underwent enucleation of her right eye and has been free of metastatic disease 3 years later. CONCLUSIONS: Tapioca melanoma of the iris must be included among the other differential diagnoses when examining patients with amelanotic iris lesions, even when iris heterochromia is not clearly evident.

RESUMO

Purpose: To present 2 cases of large atypical melanocytomas that simulate melanoma. Methods: The largest risk factors for malignant transformation from melanocytoma into malignant melanoma are a combination of lesions with a thickness greater than 2 mm, visual symptoms, and tumor margin at the disc. The patients in this report were chosen because they both presented these factors with their lesions. Results: Because the lesions were properly identified as melanocytomas of the optic disc, the decision was made to monitor them closely and treat the associated vascular activity. Ultrasounds and close observations are key in differentiating these benign lesions from malignant melanomas. Conclusions: Both patients experienced long-term stability with intravitreal injections when needed for vascular activity.

RESUMO

PURPOSE OF REVIEW: Retinoblastoma is the most common malignant intraocular tumor of childhood. Treatment and diagnostic modalities associated to this condition are changing rapidly as our understanding of this condition crystallizes. The purpose of this review is to provide an update of the current understanding of retinoblastoma. RECENT FINDINGS: Knowledge on tumorigenesis and genomic expression has expanded tremendously with the development of a mouse model for retinoblastoma. Tumor hypoxia has been identified as a significant step in the tumor progression and a novel target for future treatments. Current globe-sparing therapies, including periocular carboplatin, selective ophthalmic artery chemoreduction, intravitreal melphalan, and focal consolidation are being used and investigated actively. Diagnosis and the management of retinoblastoma is also undergoing major advances including wide-field photography, autofluorescence, and high-resolution optical coherence tomography. SUMMARY: Progressive advances in the understanding of retinoblastoma pathogenesis continue to lead treatment strategies. Improvements in the diagnosis and management of retinoblastoma are improving morbidity and mortality associated to this condition in the developed nations. However, it is of outmost importance to flatten the international boundaries to offer prompt care to retinoblastoma children in underdeveloped communities.

RESUMO

PURPOSE: To describe fundus autofluorescence (FAF) characteristics associated with choroidal osteomas and their secondary complications. METHODS: Retrospective descriptive case series of six eyes of five patients with choroidal osteomas. Findings of FAF correlated with visual acuity, clinical features, lesion characteristics, and findings from other imaging modalities. RESULTS: All 6 choroidal osteomas (100%) had totally or partially calcified, orange portions that were isoautofluorescent. Partial decalcification also produced areas of hyperautofluorescence and granular hypoautofluorescence corresponding to overlying retinal pigment epithelium mottling in 3 eyes (50%). Total decalcification with retinal pigment epithelial atrophy produced decreased FAF in 2 eyes (33%). Serous retinal detachment was present in 3 eyes (50%). When the overlying retinal pigment epithelium was viable, hyperautofluorescence as a result of elongation of the outer segments of photoreceptor was observed. In one eye where geographic atrophy of the retinal pigment epithelium was present, FAF was decreased even in the presence of serous retinal detachment. Portions of three partially or totally decalcified osteomas within the treatment field of photodynamic therapy for choroidal neovascularization were hypoautofluorescent. Four eyes (67%) had reduced foveal FAF and visual acuity <20/20, while both eyes with foveal isoautofluorescence had normal (20/20) visual acuity. CONCLUSION: Calcified portions of choroidal osteomas not previously treated with photodynamic therapy were isoautofluorescent. Decalcification and secondary complications of serous retinal detachment, choroidal neovascularization, and geographic atrophy altered foveal autofluorescence and were associated with reduced visual acuity.
