RESUMEN

ABSTRACT: Neuroendocrine tumors (NETs) are rare cancers with heterogeneous histologies, response to treatments, and prognoses. Majority of these cancers originate in the gastrointestinal tract and metastasize to the liver. We report the cases of 5 patients with low-grade NET disease with rare metastases to the choroids. Two of the patients were treated with peptide receptor radionuclide therapy (lutetium 177 [ 177 Lu]). This is the first report confirming peptide radionuclide therapy safety in patients with low-grade NET with ocular metastases.

RESUMEN

PURPOSE: To report 6 cases of diffuse choroidal hemangioma in children treated with iodine-125 plaque brachytherapy at a single tertiary care center. METHODS: Retrospective case series. RESULTS: Six pediatric patients diagnosed with diffuse choroidal hemangioma were included in the study. Preplaque visual acuity ranged from 20/150 to no light perception. All patients had extensive serous retinal detachment at presentation. An iodine-125 radioactive plaque was placed on the affected eye to administer a dose of 34.2-42.1 Gy to the tumor apex over a median of 4 days. Tumor regression and subretinal fluid resolution were observed in all eyes within 17 months of treatment. Visual acuity improved in two patients. Radiation-induced cataract and subretinal fibrosis were documented in one case, and one patient developed radiation retinopathy. No patients developed neovascular glaucoma within the follow-up time of 12-65 months. CONCLUSION: Iodine-125 plaque radiotherapy is an effective option for diffuse choroidal hemangioma, although there is a risk for radiation-induced complications.

RESUMEN

PURPOSE: To report a rare case of infusion port site tumor seeding of choroidal melanoma after pars plana vitrectomy-assisted biopsy and successful treatment with second plaque brachytherapy. METHODS: Observational case report with clinical data and diagnostic images. RESULTS: A 55-year-old Caucasian woman diagnosed with choroidal melanoma of the left eye was found to have a second intraocular tumor thirty months after plaque brachytherapy and pars plana vitrectomy-assisted tumor biopsy. The second melanoma developed at the 5 o'clock vitrectomy infusion port site. The tumor regressed after plaque brachytherapy and the patient has not developed systemic metastasis five years after diagnosis of intraocular seeding. CONCLUSION: Intraocular seeding into the infusion port site, although rare, may be encountered after pars plana vitrectomy-assisted biopsy of choroidal melanoma.

RESUMEN

BACKGROUND: The management of an outbreak of endophthalmitis associated with intravitreal bevacizumab represents a challenging real-time process involving identification of cases, treatment and mitigation measures during the outbreak. We summarize the clinical presentation and management of a cluster of endophthalmitis cases from contaminated bevacizumab, in addition to mathematical probabilistic assessment of the number of cases that define an outbreak. METHODS: A retrospective study was conducted to assess the management of an endophthalmitis outbreak after intravitreal bevacizumab (IVB) administration. Demographic data, clinical information, individual patient management and public health reporting measures were reviewed. Outcomes of patients who received prophylactic antibiotics for endophthalmitis prevention were also reviewed. Binomial tail probability calculations were performed to determine the likelihood of clusters of endophthalmitis that could inform when an outbreak was evolving that would warrant more public health notification measures and communication. RESULTS: Forty-five eyes of 42 patients who received IVB from a single batch were reviewed. Four cases of endophthalmitis from Granulicatella adiacens, a nutritionally-variant Streptococcus species, were treated successfully with intravitreal antibiotics ± vitrectomy. Thirty-four of the remaining 41 eyes were treated with prophylactic intravitreal vancomycin with no additional cases of endophthalmitis. Outbreak management also included CDC, ASRS and public health authority notification. Binominal tail probabilities demonstrated the rarity of clusters from a single batch (i.e. ~ 1/10,000 for 2 cases; 1/2 million for 3 cases). However, given the U.S. scale of IVB administration, there is an 87% chance of a cluster ≧ 2 and a 1% chance of a cluster ≧ 3 cases annually, which may guide outbreak management. A process diagram was developed to incorporate patient management and public health measures when an outbreak is suspected. CONCLUSION: Intravitreal antibiotics and vitrectomy were effective in the individual management of cases of endophthalmitis, and no serious adverse events occurred with prophylactic intravitreal vancomycin for at-risk eyes. Best practices for outbreaks should be evaluated, given their likelihood within the U.S. and the sight-threatening consequences of endophthalmitis.

RESUMEN

PURPOSE: Determine the efficacy of combination intravitreal and systemic antiviral therapy for the treatment of acute retinal necrosis (ARN) and risk factors impacting visual acuity (VA) and retinal detachment (RD) outcomes. DESIGN: Single-center retrospective case series. PARTICIPANTS: Patients with an ARN diagnosis based on clinical features and polymerase chain reaction confirmation who were treated at a tertiary referral, university-based academic practice. METHODS: Patient records were reviewed for demographic information including age and gender. Snellen VA, disease findings including RD outcomes, optic nerve involvement, and treatments were recorded. Incidence rates of major VA and RD outcomes were calculated based on the number of events and exposure times. Cox proportional hazards regression modeling and survival analyses were used to identify factors related to VA and RD outcomes over time. MAIN OUTCOME MEASURES: Logarithm of the minimal angle of resolution VA, 2-line or more VA gain, severe vision loss (SVL) of 20/200 or worse, RD development, and fellow eye involvement. RESULTS: Twenty-three eyes of 21 patients (11 male, 10 female) were reviewed. Thirteen patients (62%) had herpes simplex virus and 8 patients (38%) had varicella zoster virus. The event rate for 2-line or more VA gain was 0.49 events/eye-year (95% confidence interval [CI], 0.26-0.86 events/eye-year), whereas the rate of SVL was 0.61 events/eye-year (95% CI, 0.34-1.02 events/eye-year). Retinal detachment development was observed at a rate of 0.59 events/eye-year (95% CI, 0.33-1.00 events/eye-year). Thirteen of 23 eyes (57%) demonstrated RD with a mean time of 120 days after ARN diagnosis. With each additional quadrant of retina involved, a greater risk of RD development over time was observed (hazard ratio, 2.21; 95% CI, 1.12-4.35). Nine percent of eyes progressed with additional quadrantic involvement, despite combination systemic and intravitreal antiviral therapy; however, none of the 19 patients demonstrating unilateral ARN showed fellow-eye involvement after initiation of therapy. CONCLUSIONS: Combination intravitreal and systemic antiviral therapy for ARN can be effective in improving VA and limiting retinitis progression. Each additional quadrant of retina involved was associated with a 2.2-fold greater risk of RD, which may impact monitoring, timing of intervention, and patient counseling.

RESUMEN

PURPOSE: Cutaneous melanoma metastatic to the vitreous is very rare. This study investigated the clinical findings, treatment, and outcome of patients with metastatic cutaneous melanoma to the vitreous. Most patients received checkpoint inhibition for the treatment of systemic disease, and the significance of this was explored. DESIGN: Multicenter, retrospective cohort study. PARTICIPANTS: Fourteen eyes of 11 patients with metastatic cutaneous melanoma to the vitreous. METHODS: Clinical records, including fundus photography and ultrasound results, were reviewed retrospectively, and relevant data were recorded for each patient eye. MAIN OUTCOME MEASURES: Clinical features at presentation, ophthalmic and systemic treatments, and outcomes. RESULTS: The median age at presentation of ophthalmic disease was 66 years (range, 23-88 years), and the median follow-up from diagnosis of ophthalmic disease was 23 months. Ten of 11 patients were treated with immune checkpoint inhibition at some point in the treatment course. The median time from starting immunotherapy to ocular symptoms was 17 months (range, 4.5-38 months). Half of eyes demonstrated amelanotic vitreous debris. Five eyes demonstrated elevated intraocular pressure, and 4 eyes demonstrated a retinal detachment. Six patients showed metastatic disease in the central nervous system. Ophthalmic treatment included external beam radiation (30-40 Gy) in 6 eyes, intravitreous melphalan (10-20 µg) in 4 eyes, enucleation of 1 eye, and local observation while receiving systemic treatment in 2 eyes. Three eyes received intravitreous bevacizumab for neovascularization. The final Snellen visual acuity ranged from 20/20 to no light perception. CONCLUSIONS: The differential diagnosis of vitreous debris in the context of metastatic cutaneous melanoma includes intravitreal metastasis, and this seems to be particularly apparent during this era of treatment with checkpoint inhibition. External beam radiation, intravitreous melphalan, and systemic checkpoint inhibition can be used in the treatment of ophthalmic disease. Neovascular glaucoma and retinal detachments may occur, and most eyes show poor visual potential. Approximately one quarter of patients demonstrated ocular disease that preceded central nervous system metastasis. Patients with visual symptoms or vitreous debris in the context of metastatic cutaneous melanoma would benefit from evaluation by an ophthalmic oncologist.

RESUMEN

With fewer than 100 peer-reviewed cases reported in the world to date, the underlying etiology of torpedo maculopathy has remained elusive. In this literature review, we provide new evidence to better support, reject and unify claims regarding cause, diagnosis, and proper clinical management of this disease. We reviewed 44 case reports and case series, which included 77 patients (after exclusions). We additionally introduced 3 new cases from our clinical practice for a total of 80 cases. Ages at presentation ranged from 6 months old to 73 years old (mean: 24.2 years old). The nasal aspects of torpedo maculopathy lesions pointed toward the optic disc and localized to a kite-shaped region of the temporal macula, correlating with the anatomic junction of the superior arcuate, inferior arcuate, and papillomacular bundles of retinal nerve fiber layer distribution. No patterns were observed among the temporal aspects of the lesions. These findings support a congenital etiology of torpedo maculopathy and a possible influence of the retinal nerve fiber layer in the development of mature retinal pigment epithelium.

RESUMEN

For the treatment of choroidal melanoma, palladium-103 (Pd) and ruthenium-106 (Ru) plaque brachytherapy shows reduced toxicity compared with the historical standard iodine-125. No report has directly compared the clinical outcomes between Pd and Ru, and the reasons for the selection of one over the other remain purely theoretical. Patients with choroidal melanoma with apical tumor height up to 5 mm were included. Patients from Emory University were treated with Pd between 1993 and 2012. Patients from Cleveland Clinic were treated with Ru between 2005 and 2010. Medical records were retrospectively reviewed. We compared post-treatment visual acuity (VA), toxicity, and oncologic outcomes. Pd patients (n=124) and Ru patients (n=42) had a median follow-up of 4.2 and 5.0 years, respectively. Radiation retinopathy-free survival was similar for both radioisotopes, but Ru had lower grades of retinopathy (P=0.006). Pd was associated with worse VA preservation (≥20/40) by year 3 (odds ratio: 3.8; 95% confidence interval: 1.01-14.31, P=0.048). Pd was associated with higher distant metastases-free survival (DMFS) in multivariate analysis (hazard ratio: 0.10; 95% confidence interval: 0.02-0.38; P<0.001). Ru had lower grades of radiation retinopathy and improved long-term VA preservation, but also inferior DMFS, compared with Pd. Because of the inherent limitations of a retrospective analysis, the significance of the inferior DMFS for Ru remains unclear, although the suggestion of a slight inferiority in terms of DMFS for Ru is consistent with the other limited literature. On the basis of this study, we believe that both radioisotopes remain appropriate for the treatment of small choroidal melanomas up to 5 mm in apical height.

RESUMEN

PURPOSE: To evaluate postoperative pain level using a supplemental peribulbar injection at the conclusion of retinal surgery. DESIGN: Prospective, parallel-assigned, single-masked, randomized clinical trial. PARTICIPANTS: Fifty-eight patients undergoing scleral buckle, vitrectomy, or combined surgery. METHODS: In a single academic institutional practice, 58 patients undergoing scleral buckle, vitrectomy, or combined surgery were enrolled. Exclusion criteria included those with a risk for glaucoma, a pre-existing chronic pain disorder, among others. Patients were assigned randomly to receive a postoperative peribulbar formulation of either bupivacaine, triamcinolone acetonide, and cefazolin (group A) or bupivacaine, balanced salt solution, and cefazolin (group B). The postoperative pain score and ocular motility were assessed by a masked observer on the first postoperative day. MAIN OUTCOME MEASURES: The primary outcome measure was the postoperative pain score. Secondary outcome measures included oral analgesic use, ocular motility, and intraocular pressure (IOP). RESULTS: The mean pain scores were 2.8±2.9 for group A and 3.8±2.6 for group B (P = 0.095). Pain was absent in 28% of group A patients versus 14% of group B patients (P = 0.11). Group A required less narcotic pain medication (hydroxycodone: group A, 0.7±3 mg vs. group B, 3±6 mg; P = 0.05; oxycodone: group A, 7±7 mg vs. 9±13 mg; P = 0.2) than group B. Motility was full in group B and limited in group A (P ≤ 0.001), with no differences in mean IOP measurements at any point after surgery. CONCLUSIONS: We did not demonstrate a statistically significant reduction in mean postoperative pain scores. However, patients in group A required less hydroxycodone use and had greater akinesia, suggesting prolonged neural blockade.

RESUMEN

PURPOSE: To evaluate outcomes of choroidal melanoma patients treated with 125I or 103Pd plaque brachytherapy. METHODS AND MATERIALS: From 1993 to 2012, our institution treated 160 patients with 103Pd (56.1%) and 125 patients with 125I (43.9%) plaque brachytherapy. Tumor outcomes, visual acuity (VA), and toxicity were compared. Multivariate analyses (MVAs) and propensity score analysis were used to help address differences in baseline characteristics. RESULTS: Median followup was longer for 125I patients, 52.7 vs. 43.5 months (p < 0.01). At baseline, 103Pd patients had lower rates of VA worse than 20/200 (4.4% vs. 16%, p = 0.002), T3-T4 tumors (17.5% vs. 32.8%, p = 0.03), and transpupillary thermotherapy use (3.1% vs. 9.6%, p = 0.001). Both 103Pd and 125I provided >90% 3-year overall survival and >93% 5-year secondary enucleation-free survival. On MVA, radionuclide was not predictive for tumor outcomes. A higher percentage maintained vision better than 20/40 with 103Pd (63% vs. 35%, p = 0.007) at 3 years. MVA demonstrated 103Pd radionuclide (odds ratio [OR]: 2.12, p = 0.028) and tumor height ≤5 mm (OR: 2.78, p = 0.017) were associated with VA better than 20/40. Propensity score analysis matched 23 125I with 107 103Pd patients. 103Pd continued to predict better VA at 3 years (OR: 8.10, p = 0.014). On MVA for the development of VA worse than 20/200 or degree of vision loss, radionuclide was not significant. Lower rates of radiation retinopathy were seen with 103Pd than 125I (3 years: 47.3% vs. 63.9%, p = 0.016), with radionuclide significant in MVA. CONCLUSIONS: Both 125I and 103Pd achieve excellent tumor control. An increased probability of long-term VA better than 20/40 and reduced risk of radiation retinopathy is associated with 103Pd.

RESUMEN

PURPOSE: To report on the clinical data of seven patients with T-cell intraocular lymphoma (IOL). METHODS: Retrospective case series. RESULTS: Seven immunocompetent patients, 12 eyes, 6 women, with T-cell-IOL were included from five countries. Mean age was 53.5 years (range: 25-82). Four patients had systemic-ocular lymphoma, two had CNS-ocular lymphoma, and one had systemic-CNS- ocular lymphoma. Vitritis was the most frequent clinical sign, followed by anterior uveitis and serous retinal detachment. Cytopathologic examination was performed on all ocular specimens (vitreous in six and iris mass biopsy in one patient). Adjunctive diagnostic procedures included immunohistochemistry, molecular tests, and cytokine profiling of vitreous samples. Treatment modalities included systemic chemotherapy (five patients), intravitreal methotrexate (three patients), globe radiotherapy, and intrathecal chemotherapy. Mean survival from diagnosis was 21.7 months (range: 2-69). Two patients are still alive. CONCLUSIONS: T-cell IOL has variable clinical manifestations and prognosis. Systemic involvement, SRD, and vitreoretinal involvement were frequently observed.

RESUMEN

PURPOSE: To report a case of panuveitis, retinal vasculitis, and optic disk granuloma due to sarcoidosis. METHODS: Case report and literature review. RESULTS: A 26-year-old previously healthy African American male presented with four months of gradual progressive visual decline in the right eye. Clinical examination revealed severe panuveitis, retinal vasculitis, and large optic nerve mass lesion. Diffuse supraclavicular lymphadenopathy was also present. Histopathologic examination of the lymph node biopsy revealed granulomatous inflammation with some areas of caseous necrosis consistent with sarcoidosis. CONCLUSION: Sarcoidosis is a common cause of uveitis and retinal vasculitis. In rare cases, an optic disk granuloma may occur and can be treated with immunosuppressive therapy.

RESUMEN

Cytotoxic T-lymphocyte-associated antigen is a naturally occurring inhibitor of T-cell costimulation. Monoclonal antibody inhibition of cytotoxic T-lymphocyte-associated antigen with ipilimumab blocks this negative regulator of costimulation, promoting T-cell activation and survival, and leads to melanoma regression. Findings of the Vogt-Koyanagi-Harada (VKH) syndrome, an uveomeningitic syndrome that features neurological, auditory, ophthalmologic, and cutaneous involvement because of autoimmune targeting of melanocytic antigen, have rarely been described in association with melanoma immunotherapy. We describe a case of VKH-like syndrome in a 45-year-old HLA-A02-positive patient with metastatic melanoma treated with ipilimumab. Disruption of immune tolerance by ipilimumab led to melanoma remission while also inciting systemic and ophthalmic autoimmunity toward melanocytic antigen. These observations provide insight into the pathophysiology of the VKH syndrome, and the balance between tumor-associated tolerance and autoimmunity.

RESUMEN

PURPOSE: To describe the fundus autofluorescence (FAF) features of the inflammatory maculopathies and develop a quantification method for FAF analysis. METHODS: This is a retrospective, consecutive case series of patients with inflammatory maculopathies from two tertiary centers. The clinical findings, demographics, and FAF imaging characteristics were reviewed. Foveal autofluorescence (AF) was analyzed. Median and standard deviation (SD) of foveal AF intensity were measured. RESULTS: Thirty eyes of 15 patients were evaluated with both qualitative and quantitative FAF analysis. In acute macular neuroretinopathy, the active phase showed foveal hypoautofluorescence, which became hypoautofluorescent with resolution. In acute posterior multifocal placoid pigment epitheliopathy, multiple lesions with hypoautofluorescent centers with hyperautofluorescent borders were observed in active disease and became hypoautofluorescent with disease convalescence. In multifocal choroiditis and punctate inner choroiditis, the active hyperautofluorescent lesions progressed to inactive, hypoautofluorescent scars. Active serpiginous choroiditis showed hyperautofluorescent borders adjacent to a helicoid-shaped, hypoautofluorescent scar. Active unilateral acute idiopathic maculopathy (UAIM) showed a complex pattern of hypo- and hyperautoflourescence in the macula. The median foveal AF was the greatest in acute macular neuroretinopathy and UAIM among the maculopathies, while the greatest SD of foveal AF intensity was observed in UAIM. CONCLUSION: The active phase of the majority of inflammatory maculopathies was characterized by hyperautofluorescent lesions. Increased SD of foveal AF correlated with a mixture of hypo-and hyperautoflourescence. Median and SD may be useful metrics in foveal AF and quantifiable values that may be assessed over time as a disease process evolves. Improvements in quantification methods of FAF imaging may allow us to objectively evaluate posterior uveitis.

RESUMEN

PURPOSE: To describe a series of chorioretinal folds (CRFs) representing a clinical sign that may be associated with multiple systemic, orbital, and ophthalmologic disorders. We report the associations with systemic disease and describe 3 stages of a CRF-related maculopathy. DESIGN: Observational, retrospective case series. METHODS: We reviewed 57 affected eyes from 40 patients with the clinical sign of CRF from 1 of 2 academic institutions. A careful review of the medical histories and systemic diagnostic evaluations were conducted. Imaging studies were conducted. RESULTS: The mean age at diagnosis was 64 ± 17 years. Most eyes (n = 18) were hyperopic (+2.60 ± +2.90 diopters). There were 20 patients (50%) with some form of autoimmune disorder. Overall, the mean presenting visual acuity was 20/50, declining slightly to 20/60 over 19 ± 30 months. Ten eyes had stage 3 CRF-related maculopathy, more common in older individuals with more chronic CRFs. Four stage 3 eyes had associated choroidal neovascularization, and these eyes had 20/60 presenting visual acuity that decreased to 20/100 over approximately 1.5 years. Stage 3 eyes without choroidal neovascularization had a mean presenting visual acuity of 20/40 that decreased to 20/65 over 2.1 years. CONCLUSIONS: CRFs are associated with numerous ophthalmic and systemic disorders. A careful medical history and evaluation are essential. We describe 3 stages of a unique CRF-related maculopathy. Stage 3 resembles occult choroidal neovascularization, occurs primarily in older individuals with chronic CRFs, and is accompanied by a slow deterioration in central acuity.

RESUMEN

Vision loss associated with the idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome most commonly occurs from macular edema or complications related to neovascularization. The authors present a case of advanced IRVAN associated with a massive exudative response characterized by peripheral retinal telangiectasias, exudative retinal detachment, and macular edema with lipid maculopathy. The patient was managed successfully with visual acuity from hand motion to 20/150 using a combination of local corticosteroids, intravitreal bevacizumab, panretinal photocoagulation, and eventually pars plana vitrectomy for progressive vitreomacular traction. VEGF- and non-VEGF-mediated mechanisms appear to be involved in the pathogenesis of IRVAN given the efficacy of combination therapy. [ophthalmic surg lasers imaging retina. 2013;44:599-602.].

RESUMEN

PURPOSE: To report results of aflibercept therapy in eyes with neovascular age-related macular degeneration previously treated with bevacizumab, ranibizumab, or both. DESIGN: Retrospective, interventional, noncomparative, consecutive case series. METHODS: Ninety-six eyes from 85 patients with neovascular age-related macular degeneration who previously had received bevacizumab, ranibizumab, or both were treated with aflibercept monthly for 3 months followed by a fourth injection within 2 months. Outcomes were determined 4 ± 1 months after the first aflibercept dose and included: proportion of patients gaining or losing 2 lines or more of best-corrected visual acuity, proportion remaining within a gain or loss of 1 line, mean change in logarithm of the minimal angle of resolution visual acuity, mean change in central foveal thickness, mean change in macular cube volume, and qualitative anatomic response as assessed by spectral-domain optical coherence tomography. RESULTS: At baseline, 82 (85%) eyes had signs of active exudation despite a mean of 17 previous anti-vascular endothelial growth factor injections. At final visit, 82 (85%) remained stable within a gain or loss of 1 line, 7 (7%) gained 2 lines or more, and 7 (7%) lost 2 lines or more of best-corrected visual acuity. Mean logarithm of the minimal angle of resolution visual acuity showed minimal change 0.02 (range, -0.46 to 0.70; P = .14). Mean central foveal thickness decreased -18 µm (range, -242 to 198 µm; P = .06). Mean macular volume decreased -0.27 mm(3) (95% confidence interval, -0.4 to -0.1 mm(3); P = .004). On qualitative analysis, 4 (5%) eyes had complete resolution of exudative fluid, 40 (49%) showed partial resolution, 26 (32%) remained unchanged, and 12 (14%) showed worsened exudative fluid. CONCLUSIONS: Aflibercept seems to be an effective alternative for neovascular age-related macular degeneration patients previously treated with bevacizumab, ranibizumab, or both at 4 months of follow-up. Most treated eyes demonstrated stable visual acuity and anatomic improvements by spectral-domain optical coherence tomography.
