RESUMO

PURPOSE: To investigate the incidence, risk factors, and their influence on visual outcomes of subretinal hemorrhage (SRH) in patients with neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy(PCV) who discontinue treatment. METHODS: This retrospective study included 148 patients with nAMD and PCV who discontinued treatment. The development of a 3-disc area or greater extent of SRH after treatment discontinuation was identified. Visual acuity at the final visit was compared between patients with and those without SRH. Factors associated with SRH were then analyzed. RESULTS: During the mean 56.8 ± 18.2 months of follow-up, treatment was discontinued at a mean 24.1 ± 16.3 months after diagnosis. SRH developed in 24 (16.2%) patients at a mean 21.5 ± 17.6 months after treatment discontinuation. The visual acuity at the final follow-up was significantly worse in patients with SRH than in those without SRH (P < 0.001). There was a significant difference in the incidence of SRH among the different types of macular neovascularization (MNV) (P = 0.024). In particular, the incidence of type 3 MNV was relatively high (36.0%). CONCLUSIONS: The development of SRH may lead to very poor visual prognosis in patients who discontinue treatment. The high risk of SRH in type 3 MNV suggests the need for caution when choosing treatment discontinuation in cases of type 3 MNV.

RESUMO

PURPOSE: To describe the clinical and multimodal imaging features of bacillary layer detachment (BD), and its response to intravitreal anti-vascular endothelial growth factor therapy, in eyes with macular neovascularization. METHODS: Retrospective, observational case series of 14 eyes (14 patients, 7 men) imaged with eyes (14 patients, 7 men) were imaged with spectral-domain optical coherence tomography, and either fluorescein angiography or optical coherence tomography angiography. Therapeutic response was monitored with serial imaging and best-corrected visual acuity assessments. RESULTS: The mean age was 75 ± 13 (range: 45-96) years, with mean follow-up duration of 27 ± 21 (range: 1-56) months. Neovascular age-related macular degeneration was found in 71% (10/14) eyes. Type 2 macular neovascularization lesions were associated with BD in all 14 eyes. Subretinal hemorrhage was noted in 79% (11/14) eyes. BD promptly resolved after intravitreal antivascular endothelial growth factor therapy in all eyes. The baseline best-corrected visual acuity improved from logarithm of the minimum angle of resolution 0.84 ± 0.32 (Snellen equivalent 20/138) to logarithm of the minimum angle of resolution 0.48 ± 0.31 (Snellen equivalent 20/60) at the last follow-up, with treatment of the macular neovascularization. CONCLUSION: Type 2 macular neovascularization and subretinal hemorrhage are associated with BDs, which may be due to a rapid influx of exudative fluid into the potential space between the external limiting membrane and ellipsoid zone. Intravitreal antivascular endothelial growth factor therapy results in rapid resolution of BDs and visual improvement in most eyes.

RESUMO

BACKGROUND: Roxadustat is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor approved in China for dialysis-dependent CKD anemia. METHODS: This phase 3, 24-week, double-blind, double-dummy study evaluated roxadustat's noninferiority to darbepoetin alfa for hemodialysis-dependent CKD anemia. We randomly assigned Japanese patients to oral roxadustat three times weekly or to darbepoetin alfa injections once weekly, titrating doses to maintain hemoglobin between 10-12 g/dl. The primary end point was change of average hemoglobin from baseline to weeks 18-24 (∆Hb18-24). Secondary end points were average hemoglobin and proportion of patients with hemoglobin between 10-12 g/dl (maintenance rate) at weeks 18-24, and iron parameters. Safety assessments included treatment-emergent adverse events and adjudicated ophthalmologic findings. RESULTS: We randomly assigned 303 patients to roxadustat (n=151) or darbepoetin alfa (n=152). The difference between roxadustat and darbepoetin alfa in ∆Hb18-24 was -0.02 g/dl (95% confidence interval, -0.18 to 0.15), confirming roxadustat's noninferiority to darbepoetin alfa. Average hemoglobin at weeks 18-24 with roxadustat was 10.99 g/dl (95% confidence interval: 10.88 to 11.10), confirming its efficacy. Among patients with one or more hemoglobin value during weeks 18-24, the maintenance rate was 95.2% with roxadustat and 91.3% with darbepoetin alfa. Serum iron, ferritin, and transferrin saturation remained clinically stable with roxadustat; transferrin and total iron binding capacity increased through week 4 before stabilizing. Common treatment-emergent adverse events were nasopharyngitis, shunt stenosis, diarrhea, contusion, and vomiting. The proportion of patients with new or worsening retinal hemorrhage was 32.4% with roxadustat and 36.6% with darbepoetin alfa. We observed no clinically meaningful changes in retinal thickness groups. CONCLUSIONS: Roxadustat maintained hemoglobin within 10-12 g/dl in patients on hemodialysis and was noninferior to darbepoetin alfa. Treatment-emergent adverse events were consistent with previous reports. CLINICAL TRIAL REGISTRY NAME AND REGISTRATION NUMBER: A Study of Intermittent Oral Dosing of ASP1517 in Hemodialysis Chronic Kidney Disease Patients with Anemia, NCT02952092 (ClinicalTrials.gov).

RESUMO

SIGNIFICANCE: Amiodarone is an excellent antiarrhythmic medication; however, it has numerous systemic and ocular adverse effects. PURPOSE: We aimed to improve our understanding of amiodarone and its ocular adverse effects by performing a systematic review and meta-analysis of published case reports. METHODS: This systematic review was reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. We used the MEDLINE database, primarily through PubMed, and used keywords (amiodarone, eye, eye diseases, visual/ocular adverse effects/manifestations) to identify case reports of ocular adverse effects after amiodarone use. The initial search resulted in 92 total case reports. However, after excluding nonrelevant case reports, 25 cases were selected for the final analysis. RESULTS: Among the patients in the 25 case reports, 18 were male (72%), and the median age was 66 ± 9.9 years. In 15 cases (60%), the patients reported halos around light and/or decrease in vision after amiodarone use. The most common ophthalmic examination findings were cornea verticillata/vortex keratopathy in 19 cases (76%), followed by different patterns of papilledema and retinal hemorrhages in 5 cases (20%). Discontinuation of amiodarone was the most common intervention, followed by application of topical heparin. Outcomes among case reports were variable. CONCLUSIONS: Cornea verticillata/vortex keratopathy was the most common ocular adverse effect in cases where amiodarone was administered. Early recognition of amiodarone-induced ocular adverse effects is imperative to prevent worsening keratopathy or uncommon adverse effects. Collaboration between physicians prescribing amiodarone-to recognize the ocular symptoms-and referral to eye care physicians are important.

RESUMO

SIGNIFICANCE: There are several isolated reports of systemic medications or medical conditions that can cause acute transient myopic shifts along with other ocular sequelae, but rarely has this been reported for the combination antibiotic sulfamethoxazole-trimethoprim. PURPOSE: This case illustrates a rarely seen condition that may result from treatment with sulfamethoxazole-trimethoprim and result in serious, vision-threatening conditions. These can be treated by immediate discontinuation of the drug, steroids, ocular hypertensive medication, and cycloplegia, depending on the circumstances. CASE REPORT: A 20-year-old woman presented complaining of blindness upon waking. She had been experiencing fever, malaise, and significant abdominal pain for weeks. Blood culture revealed infection with Staphylococcus aureus and Escherichia coli for which she was prescribed sulfamethoxazole (800 mg) and trimethoprim (160 mg) twice daily. After a week of treatment, she awoke unable to see. Examination revealed narrowed angles, bilateral 6-D myopic shift, macular folding with scattered microaneurysms, and intraretinal hemorrhages with mild macular edema and field defects. The condition resolved with discontinuation of the drug and use of steroids, ocular hypertensive, and cycloplegic agents. Her visual acuity returned to near normal within 3 days. Resolution of macular edema, field defects, and hemorrhages followed. CONCLUSIONS: An adverse reaction possibly caused by sulfamethoxazole-trimethoprim is described causing ciliochoroidal effusion resulting in acute myopic shift and other sequelae. Successful treatment is demonstrated, and implications are discussed.

RESUMO

PURPOSE: Because patients often take iron supplements without medical indication, and iron can accumulate in vascular endothelial cells, the authors evaluated the association of oral iron supplementation with retinal/subretinal hemorrhage in patients with neovascular age-related macular degeneration. METHODS: A post hoc secondary data analysis of comparison of age-related macular degeneration treatments trials was performed. Participants were interviewed for use of oral iron supplements. Trained readers evaluated retinal/subretinal hemorrhage in baseline fundus photographs. Adjusted odds ratios from multivariate logistic regression models assessed the association between iron use and baseline hemorrhage adjusted by age, sex, smoking, hypertension, anemia, and use of antiplatelet/anticoagulant drugs. RESULTS: Among 1,165 participants, baseline retinal/subretinal hemorrhage was present in the study eye in 71% of 181 iron users and in 61% of 984 participants without iron use (adjusted odds ratio = 1.47, P = 0.04), and the association was dose dependent (adjusted linear trend P = 0.048). Iron use was associated with hemorrhage in participants with hypertension (adjusted odds ratio = 1.87, P = 0.006) but not without hypertension. The association of iron use with hemorrhage remained significant among hypertensive participants without anemia (adjusted odds ratio = 1.85, P = 0.02). CONCLUSION: Among participants of comparison of age-related macular degeneration treatments trials, the use of oral iron supplements was associated with retinal/subretinal hemorrhage in a dose-response manner. Unindicated iron supplementation may be detrimental in patients with wet age-related macular degeneration.

RESUMO

PURPOSE: To expand understanding of presentation, diagnosis, and outcomes of hemorrhagic occlusive retinal vasculitis (HORV). DESIGN: Retrospective case series. PARTICIPANTS: Thirty-six eyes of 23 patients. METHODS: The American Society of Cataract and Refractive Surgery (ASCRS) and the American Society of Retina Specialists (ASRS) formed a joint task force to define clinical characteristics of HORV and to study its prevalence, cause, treatment, and outcomes. An online registry was established on both societies' web sites. Surveys were e-mailed to members of both societies soliciting cases of suspected HORV. A literature search was performed to uncover additional cases. MAIN OUTCOME MEASURES: Historical data including intraoperative characteristics, images, treatment regimens, and visual and anatomic outcomes. RESULTS: Characteristic findings of HORV included unremarkable postoperative day 1 undilated examination, delayed-onset painless vision loss, mild anterior chamber and vitreous inflammation, sectoral retinal hemorrhages in areas of ischemia, and predilection for venules and peripheral involvement. Based on predetermined diagnostic criteria, 36 eyes of 23 patients were diagnosed with HORV. All eyes received intraocular vancomycin via intracameral bolus (33/36), via intravitreal injection (1/36), or through the irrigation bottle (2/36). Patients sought treatment with HORV 1 to 21 days after surgery or intravitreal injection. Visual results usually were poor: 22 of 36 eyes (61%) had 20/200 or worse visual acuity and 8 of 36 eyes (22%) had no light perception (NLP). Neovascular glaucoma developed in 20 of 36 eyes (56%). Seven eyes received additional intravitreal vancomycin after surgery; 5 of these 7 eyes had NLP visual acuity at the most recent examination. Three eyes received intravitreal corticosteroids and had final visual acuities of 20/40, 20/70, and hand movements. CONCLUSIONS: Hemorrhagic occlusive retinal vasculitis is a rare, potentially devastating condition that can develop after cataract surgery or intraocular injection. All cases in this series were associated with intraocular vancomycin. Disease course and findings suggest that HORV is caused by a delayed hypersensitivity reaction to vancomycin. Early treatment with corticosteroids likely is beneficial. Subsequently, anti-vascular endothelial growth factor injections and panretinal photocoagulation are important to prevent neovascular glaucoma, a common complication. Avoidance of additional intravitreal vancomycin is recommended if HORV is suspected.

RESUMO

Background K-912 also known as NC-6300 is a novel epirubicin pro-drug conjugate developed using micellar nanoparticle technology. We conducted a first-in-human, Phase 1, open-label, non-randomized dose escalation study to evaluate the safety, tolerability, efficacy, and pharmacokinetics of K-912 administered as monotherapy in patients with advanced or recurrent solid tumors. Methods Patients aged 41 to 72 years with histologically or cytologically confirmed advanced or recurrent malignant solid tumors either refractory to standard therapy or had no other viable treatment options were enrolled. K-912 was administered as a 10-min intravenous infusion every three weeks. Doses were increased in a step-wise manner based on a predetermined series: 15, 30, 60, 80, 100, 130, 170, and 225 mg/m2. The appropriateness of doses above 60 mg/m2 was assessed using a Bayesian continual reassessment model. Treatment-emergent adverse events and tumor response were evaluated according to internationally accepted criteria. Results Nineteen patients were treated with K-912. No additional adverse events expected with anthracyclines were observed. While the number of patients treated at the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D) were small, MTD and RP2D were established to be 170 mg/m2. Partial response was observed in one patient with breast cancer treated at 100 mg/m2, yielding an objective response rate of 5% (1/19). Stable disease was observed in 10 patients. The human pharmacokinetic profile of K-912 was consistent with that observed from nonclinical studies in rats and monkeys. Conclusions This study showed that K-912 was well tolerated in patients with various solid tumors and exhibited less toxicity than conventional epirubicin formulations.

RESUMO

PURPOSE: To evaluate the association between use of antiplatelet or anticoagulant drugs and retinal or subretinal hemorrhage in participants with neovascular age-related macular degeneration (AMD) in the Comparison of AMD Treatments Trials (CATT). DESIGN: Cohort study within CATT. PARTICIPANTS: Participants in CATT with untreated active neovascular AMD (n = 1185). METHODS: Participants were interviewed for use of antiplatelet or anticoagulant drugs. Trained readers evaluated photographs for the presence and size of retinal or subretinal hemorrhage at baseline and years 1 and 2. Associations between use of antiplatelet or anticoagulant drugs and hemorrhage were evaluated among all participants and by baseline hypertension status using multivariate logistic regression models. MAIN OUTCOME MEASURES: Odds ratio for association with antiplatelet or anticoagulant use. RESULTS: Among 1165 participants with gradable photographs, 724 (62.1%) had retinal or subretinal hemorrhage at baseline; 84.4% of hemorrhages were 1 disc area (DA) or less, 8.1% were 1 to 2 DA, and 7.5% were more than 2 DA. At baseline, 608 participants (52.2%) used antiplatelet or anticoagulant drugs, including 514 participants (44.1%) using antiplatelets only, 77 (6.6%) using anticoagulants only, and 17 (1.5%) using both. Hemorrhage was present in 64.5% of antiplatelet or anticoagulant users and in 59.6% of nonusers (P = 0.09; adjusted odds ratio [OR], 1.18; 95% confidence interval, 0.91-1.51; P = 0.21). Neither presence nor size of baseline hemorrhage was associated with the type, dose, or duration of antiplatelet or anticoagulant use. Forty-four of 1078 participants (4.08%) had retinal or subretinal hemorrhage detected on 1- or 2-year photographs; these hemorrhages were not associated with antiplatelet or anticoagulant use at baseline (P = 0.28) or during follow-up (P = 0.64). Among participants with hypertension (n = 807), antiplatelet or anticoagulant use was associated with a higher rate of hemorrhage at baseline (66.8% vs. 56.4%; adjusted OR, 1.48; P = 0.01), but not size of retinal or subretinal hemorrhage (P = 0.41). CONCLUSIONS: Most retinal or subretinal hemorrhages in eyes enrolled in CATT were less than 1 DA. Among all CATT participants, antiplatelet or anticoagulant use was not associated significantly with hemorrhage, but it was associated significantly with hemorrhage in participants with hypertension.

RESUMO

PURPOSE: To assess the development of vision-threatening lesions at least 3.5 years after initiating anti-vascular endothelial growth factor (VEGF) for choroidal neovascularization (CNV) in eyes with age-related macular degeneration (AMD). DESIGN: Retrospective cohort study. PARTICIPANTS: A total of 75 patients (81 eyes) with CNV secondary to AMD who received intravitreous anti-VEGF treatment and were followed for at least 3.5 years after initiating treatment. METHODS: Retrospective record review of patients initiating anti-VEGF treatment between November 2005 and June 2008 at a university-based institution for whom at least 3.5 years of follow-up was available at the same institution. MAIN OUTCOME MEASURES: Predominantly hemorrhagic lesions or geographic atrophy (GA). RESULTS: Among 75 patients (81 eyes; 59% were women; median age, 78 years), mean follow-up was 4.9 years and at least 6 years for 40%. Median visual acuity (VA) was 20/80 (interquartile range [IQR], 20/50-20/100) initially, 20/63 (IQR, 20/40-20/160) at 2 years, 20/80 (IQR, 20/40-20/200) at 3.5 years, and 20/63 (IQR 20/32-20/200) at 6 years. Six eyes (7%) had predominantly hemorrhagic lesions initially, whereas this developed in an additional 3 eyes (4%, 95% confidence interval [CI], 1% to 10%) in 3.5 years and in 1 additional eye (1%, 95% CI, 0.03% to 7%) at more than 3.5 years of follow-up. Initially, GA within or overlapping the boundary of the entire CNV was present in 4 eyes (5%) and outside this boundary in 8 eyes (10%). Geographic atrophy enlarged in each eye over time. The only eyes that developed GA outside the CNV boundary were those that had GA outside the lesion at baseline. Additional atrophy within the boundary of CNV defined at baseline, termed "atrophic disciform scars," developed in 5 eyes (6%), all within 4 years of treatment initiation. CONCLUSIONS: Longer-term follow-up of neovascular AMD managed with anti-VEGF therapy suggests that predominantly hemorrhagic lesions may develop within 3.5 years of initiating therapy and more than 3.5 years after initiating therapy. In contrast, new areas of GA beyond the boundaries of the CNV lesion as defined at initiation of anti-VEGF therapy seem unlikely to develop if there is no GA outside of the CNV lesion initially.

RESUMO

PURPOSE: To describe a syndrome of hemorrhagic occlusive retinal vasculitis (HORV) that developed after seemingly uncomplicated cataract surgery. DESIGN: Retrospective case series. SUBJECTS: Eleven eyes of 6 patients from 6 different institutions. METHODS: Cases were identified after discussion among retina specialists. The findings on presentation, clinical course, and outcome of a series of 7 eyes of 4 patients were compared with a previous report of 4 eyes of 2 patients, and data from both series were combined for a comprehensive analysis. MAIN OUTCOME MEASURES: Historical data, examination findings, imaging results, systemic evaluation findings, treatment regimens, and visual outcomes. RESULTS: Eleven eyes of 6 patients underwent otherwise uncomplicated cataract surgery, receiving viscoelastic and prophylactic intracameral vancomycin during the procedure. Despite good initial vision on postoperative day 1, between 1 to 14 days after surgery, all eyes demonstrated painless vision loss resulting from HORV. Extensive ocular and systemic evaluations were unrevealing in all patients. All patients were treated with aggressive systemic and topical corticosteroids. Additional treatments included systemic antiviral medication in 4 patients, intravitreal antibiotics in 4 eyes, and pars plana vitrectomy in 4 eyes. Skin testing for vancomycin sensitivity showed negative results in 3 patients and was not performed in the others. Neovascular glaucoma developed in 7 eyes, and all eyes received intravitreal anti-vascular endothelial growth factor (VEGF) injection, panretinal photocoagulation, or both for retinal ischemia. Final visual acuity was less than 20/100 in 8 of 11 eyes. CONCLUSIONS: Postoperative HORV is an exceedingly rare and potentially devastating condition that can occur after otherwise uncomplicated cataract surgery. Although the precise cause remains unknown, this disease may represent a delayed immune reaction similar to vancomycin-induced leukocytoclastic vasculitis. Despite treatment with high-dose corticosteroids, antiviral medication, and early vitrectomy in many patients, visual outcomes typically were poor in this series. Early intervention with intravitreal anti-VEGF medication and panretinal photocoagulation may help to prevent additional vision loss resulting from neovascular glaucoma.

RESUMO

BACKGROUND: Fingolimod is the first oral agent used for treatment of relapsing-remitting multiple sclerosis. Macular edema, but not retinal hemorrhage, is a well-known adverse effect of fingolimod treatment. To the best of our knowledge, this is the first case report of extensive retinal hemorrhages following fingolimod treatment. CASE PRESENTATION: A 31-year-old male with relapsing-remitting multiple sclerosis developed macular edema and retinal hemorrhages in his left eye, 1 month after starting fingolimod treatment; treatment was then discontinued. The hemorrhages were flame-shaped, and were extensive along retinal arteries and veins. The hemorrhages started to decrease at 4 weeks and disappeared completely at 24 weeks after cessation of fingolimod treatment. CONCLUSIONS: Occurrence of retinal hemorrhage warrants careful follow-up for multiple sclerosis patients treated with fingolimod.

RESUMO

BACKGROUND: Patients with age-related macular degeneration (AMD) often receive concomitant systemic blood thinning medications. These are known to increase the risk of severe hemorrhage also in connection with AMD, which can lead to extensive subretinal hemorrhaging. OBJECTIVE: The purpose of this study was to investigate the proportion of patients with AMD and concomitant blood thinning treatment, including the type and reason for blood thinning treatment. METHODS: This survey was prospectively conducted at the University Eye Hospital, Bonn, Germany. Volunteers were recruited during retinal consultations and the consultations for intravitreal injections (IVOM). RESULTS: The questionnaire was completed by 178 patients. The mean age was 81.7 years (58-100) and 101 patients (57.7%) were undergoing blood thinning treatment. The majority of patients were taking antiplatelet agents (n = 59; 58.4%), especially ASA (n = 55; 54.5%). Direct oral anticoagulants (DOAC) were taken by 33 patients (32.7%), including most frequently apixaban (17.8%). Vitamin K antagonists (VKA) was taken by 4 patients (4%). The most common reason for blood thinning treatment was atrial fibrillation (n = 32, 31.7%), followed by stent implantation (n = 20, 19.8%) and stroke (n = 12, 11.9%) but 13 patients (12.9%) did not know why they were undergoing blood thinning treatment. No clear indications for the use of blood thinners were found in 31 patients (30.7%). CONCLUSION: A large proportion of patients with AMD undergo blood thinning treatment; however, not every patient has a clear indication. Due to the increased risk of bleeding, the use of blood thinners should be critically evaluated in close cooperation with primary care physicians and cardiologists.

RESUMO

OBJECTIVE: To evaluate long-term safety of intravitreal ranibizumab 0.5-mg injections in neovascular age-related macular degeneration (nAMD). DESIGN: Twenty-four-month, open-label, multicenter, phase IV extension study. PARTICIPANTS: Two hundred thirty-four patients previously treated with ranibizumab for 12 months in the EXCITE/SUSTAIN study. METHODS: Ranibizumab 0.5 mg administered at the investigator's discretion as per the European summary of product characteristics 2007 (SmPC, i.e., ranibizumab was administered if a patient experienced a best-corrected visual acuity [BCVA] loss of >5 Early Treatment Diabetic Retinopathy Study letters measured against the highest visual acuity [VA] value obtained in SECURE or previous studies [EXCITE and SUSTAIN], attributable to the presence or progression of active nAMD in the investigator's opinion). MAIN OUTCOME MEASURES: Incidence of ocular or nonocular adverse events (AEs) and serious AEs, mean change in BCVA from baseline over time, and the number of injections. RESULTS: Of 234 enrolled patients, 210 (89.7%) completed the study. Patients received 6.1 (mean) ranibizumab injections over 24 months. Approximately 42% of patients had 7 or more visits at which ranibizumab was not administered, although they had experienced a VA loss of more than 5 letters, indicating either an undertreatment or that factors other than VA loss were considered for retreatment decision by the investigator. The most frequent ocular AEs (study eye) were retinal hemorrhage (12.8%; 1 event related to study drug), cataract (11.5%; 1 event related to treatment procedure), and increased intraocular pressure (6.4%; 1 event related to study drug). Cataract reported as serious due to hospitalization for cataract surgery occurred in 2.6% of patients; none was suspected to be related to study drug or procedure. Main nonocular AEs were hypertension and nasopharyngitis (9.0% each). Arterial thromboembolic events were reported in 5.6% of the patients. Five (2.1%) deaths occurred during the study, none related to the study drug or procedure. At month 24, mean BCVA declined by 4.3 letters from the SECURE baseline. CONCLUSIONS: The SECURE study showed that ranibizumab administered as per a VA-guided flexible dosing regimen recommended in the European ranibizumab SmPC at the investigator's discretion was well tolerated over 2 years. No new safety signals were identified in patients who received ranibizumab for a total of 3 years. On average, patients lost BCVA from the SECURE study baseline, which may be the result of disease progression or possible undertreatment.

RESUMO

BACKGROUND: The objective of this study was to prospectively assess the risk of bleeding from vitreoretinal surgery in a continuous unbiased cohort of patients taking unsuspended antiplatelet or anticoagulant therapy. DESIGN: Prospective hospital-based study. PARTICIPANTS: Eighty-five patients taking unsuspended aspirin, clopidogrel and/or warfarin therapy undergoing all forms of vitreoretinal surgery at The Mater Misericordiae University and The Mater Private Hospital, Dublin, Ireland. METHODS: Consecutive patients undergoing vitreoretinal surgery taking unsuspended antiplatelet or anticoagulant therapy over a 1-year period were included in this prospective study to evaluate the intraoperative and postoperative bleeding complications. MAIN OUTCOME MEASURES: The intraoperative and postoperative bleeding rates. RESULTS: One hundred and seven vitreoretinal procedures were performed on 85 patients taking unsuspended antiplatelet or anticoagulant therapy. The intraoperative bleeding rate was 23%, the majority of which consisted of mild bleeding into the vitreous cavity during vitrectomy. The postoperative bleeding rate was 22%, consisting of 3.7% anterior chamber haemorrhage, 11% dispersed vitreous cavity haemorrhage, 4.7% dense vitreous cavity haemorrhage, 0.9% subretinal haemorrhage and 1.9% localized choroidal haemorrhage. The single greatest significant independent predictor of intraoperative bleeding was proliferative diabetic retinopathy and of postoperative bleeding was the presence of diabetes mellitus. CONCLUSIONS: There were no cases of uncontrolled intraoperative haemorrhage or serious postoperative choroidal haemorrhage. Mild haemorrhagic oozing during vitrectomy and dispersed vitreous cavity haemorrhage postoperatively were common. For the majority of patients taking antiplatelet or anticoagulant medication, these agents can be safely continued in the vitreoretinal surgical perioperative period.

RESUMO

This study describes three unilateral cases of hemorrhagic occlusive retinal vasculitis (HORV) after cataract surgery and a review of the literature until February 2022, including 21 articles reporting HORV cases. Altogether, 61 eyes (41 patients) were included. Twenty patients had bilateral and 21 patients had unilateral HORV. Prophylactic vancomycin was given to all patients. Additional vancomycin use was associated with the worst outcome. The mean time to HORV was 9 days post-cataract surgery. In bilateral cases, the median time between surgeries was 7 days. Visual acuity was < 20/400 in 48%, with no light perception in 20%. Neovascular glaucoma developed in 43%. Central macular thickening or hyperreflectivity of the inner retinal layers on optical coherence tomography was associated with worse outcomes. Corticosteroid treatment, early panretinal laser photocoagulation, or anti-vascular endothelial growth factor therapy, and prophylaxis alternative to vancomycin is recommended.
