RESUMEN

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.

RESUMEN

Purpose: To evaluate the safety and clinical outcomes of combined phacoemulsification with intraocular lens (IOL) placement and microincision vitrectomy surgery (MIVS) in adult patients with concomitant cataract and vitreoretinal disease. Methods: A consecutive series of patients with comorbid vitreoretinal disease and cataract who had combined phacoemulsification with IOL placement and MIVS was retrospectively analyzed. The main outcome measures were visual acuity (VA) and intraoperative and postoperative complications. Results: The analysis comprised 648 eyes of 611 patients. The median follow-up was 26.9 months (range, 12-60 months). The most common vitreoretinal pathology was intraocular tumor (53%). The best-corrected Snellen VA improved from 20/192 at baseline to 20/46 at the 12-month follow-up. The most frequent intraoperative complication was capsule tear (3.9%). The most common postoperative adverse events after 3 months of follow-up (mean, 24 months) were vitreous hemorrhage (3.2%) and retinal detachment (1.8%). No patient developed endophthalmitis. Conclusions: Combined phacoemulsification with IOL placement and MIVS is a safe, effective technique to manage a broad range of vitreoretinal diseases in patients with significant cataract.

RESUMEN

SIGNIFICANCE: This article reports two cases reported of combined treatment with topical dorzolamide and intravitreal bevacizumab injections, successfully treating small full-thickness macular hole without the need for traditional macular hole surgery. PURPOSE: This study aimed to report the potential effectiveness of combination treatment with topical dorzolamide and bevacizumab intravitreal injection therapy for small macular holes. CASE REPORTS: Case 1 was a 68-year-old woman presented with distorted and decreased vision in her right eye for 9 months. Fundus examination showed a full-thickness macular hole, which was confirmed with spectral domain optical coherence tomography measuring 96 µm. Treatment with topical dorzolamide and intravitreal bevacizumab 1.25 mg/0.05 mL injections was initiated. Spectral domain optical coherence tomography showed gradual improvement of the full-thickness macular hole with complete hole closure and visual improvement in just 1 month. Case 2 was a 73-year-old woman who presented with distorted and decreased vision in her right eye for 8 months. Fundus examination showed a full-thickness macular hole in the right eye, confirmed with spectral domain optical coherence tomography, measuring 76 µm. Treatment with topical dorzolamide and intravitreal bevacizumab 1.25 mg/0.05 mL injections was initiated. Spectral domain optical coherence tomography showed gradual improvement of the full-thickness macular hole with complete closure at 2 months and improvement in visual acuity. CONCLUSIONS: The combination of topical dorzolamide and bevacizumab intravitreal injection is a reasonable consideration for small macular holes with vascular components before considering surgery. Both cases had early macular closure in less than 3 months.

RESUMEN

OBJECTIVE: To report a consecutive series of compassionate, off-label use of intravitreal brolucizumab as a rescue therapy for complex, non-responsive macular edema. This report delineates primary diagnosis, indications for treatment, adverse events, and visual and anatomic outcomes after intravitreal brolucizumab. METHODS: A retrospective review of a consecutive clinical case series of 110 eyes treated with intravitreal brolucizumab between January 1st and March 1st. 2020. All patients were included if they received intravitreal brolucizumab in an off-label delivery and had ongoing macular edema in the setting of prior, multiple intravitreal anti-VEGF and/or intravitreal triamcinolone acetonide. All patients had spectral domain OCT documented before, at the time of, and in serial follow-up after intravitreal brolucizumab. RESULTS: Ninety-eight of 98 patients had marked decrease in macular edema. Indications for treatment were assigned to the primary etiologic diagnosis leading to the macular edema secondary to radiation retinopathy, complex epiretinal membrane, or complex diabetic retinopathy. In this series, sdOCT central point thickness decreased by an average of 71.5 microns, subretinal fluid resolved, and visual acuity was improved in 40% (greater than two Snellen lines) and stable in 60% (within two Snellen lines). No patient experienced a severe adverse event to specifically include vitritis and/or vasculitis. CONCLUSION: In this series, brolucizumab intravitreal injection was associated with significant improvement in macular edema in each diagnostic category. No serious complications to treatment were found in this series. Brolucizumab, though associated with known intraocular inflammation and vasculitis, demonstrated marked benefit in these complex eyes previously unresponsive to aggressive intravitreal pharmacotherapy.

RESUMEN

Purpose: This work describes the 2-year results of the Aflibercept for Radiation Maculopathy (ARM) randomized clinical study that evaluated intravitreal vascular endothelial growth factor antagonist therapy in radiation maculopathy delivering aflibercept using a second-year collapsed, every-6-weeks, treat-and-adjust interval. Methods: Forty patients were enrolled in an institutional review board-approved clinical trial and randomly assigned to aflibercept treatment via 1 of 2 regimens: fixed, every-6-week treatment or variable, treat-and-adjust therapy centered around 6 weeks. All patients had a diagnosis of treated uveal melanoma with documented tumor control, and they had visually compromising radiation maculopathy. At conclusion of year 1, the first 30 patients were offered a collapsed single-arm variable of an every-6-weeks treat-and-adjust aflibercept injection schedule for an additional treatment year. Results: Baseline best-corrected visual acuity (BCVA) was 20/63 at ARM study entry 20/62 at the institution of the year-2 extension. At ARM study entry baseline, spectral domain-optical coherence tomography mean central retinal thickness was 432 µm and was 294 µm at the same institution. At the 2-year study's conclusion, 76.7% (23 of 30) of eyes were better than 20/50, and only 6.7% (2 of 30) ended with a BCVA below 20/200. Final mean BCVA was 20/62 and final mean spectral domain-optical coherence tomography central retinal thickness was 286 µm, but as in year 1, this reduction in number of injections was not statistically significant. Conclusions: Aflibercept is effective in treating radiation maculopathy with maintained visual acuity at 2 years but continues to require an ongoing treatment approach to stabilize radiation maculopathy.

RESUMEN

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.

RESUMEN

PURPOSE: A private tertiary care ophthalmology practice was analyzed to see how Hurricane Irma affected patient care. METHODS: Eighty-two patients (96 eyes) that missed their scheduled appointments due to Hurricane Irma were reviewed. Patients were being treated with intravitreal injection therapy for diabetic retinopathy, radiation retinopathy, vein occlusions, choroidal neovascularization, or neovascular age-related macular degeneration. The authors assessed patients' visual acuity and macular thickness changes before the hurricane and their initial visit after the storm. Emergency preparedness was also evaluated in this setting. RESULTS: Patients on average were delayed 19.6 days. On average, best-corrected visual acuity was 20/97 (0.7 logMAR) before the hurricane and 20/82 (0.6 logMAR) after the storm. The average central macular thickness change was -1.30 µm. Intraocular pressure was not significantly affected and there were no ocular complications associated with the delay in therapy. A back-up electrical system was in place to maintain appropriate temperature for storage of medications and proper access to medical records. CONCLUSION: The authors believe that minimizing delay in treatment was the most important contributing factor to preventing worsening of ocular disease. Ophthalmology clinics should strive for appropriate treatment modality regarding injection intervals prior to a natural disaster and emergency planning with excellent patient communication both before and after natural disasters.

RESUMEN

PURPOSE: To evaluate 2 treatment approaches to intravitreal vascular endothelial growth factor antagonist therapy in radiation maculopathy comparing aflibercept delivered by either a 6-week treatment interval or treat-and-adjust interval. DESIGN: Randomized, prospective clinical trial. METHODS: Forty consecutive patients were enrolled in an institutional review board-approved clinical trial and randomized to aflibercept treatment via 1 of 2 regimens: (1) fixed, every-6-weeks treatment or (2) variable, treat-and-adjust treatment centered around 6 weeks. All patients had a diagnosis of treated uveal melanoma with documented tumor control. All patients showed visually compromising radiation maculopathy confirmed by a decline in best-corrected visual acuity (BCVA) and spectral-domain (SD) OCT documentation of radiation maculopathy. MAIN OUTCOME MEASURES: Best-corrected visual acuity and SD OCT central retinal thickness at 1 year. RESULTS: Thirty-nine of 40 patients completed the trial (97.5%) with 1 year of follow-up. Baseline study entry BCVA was 20/63 and was maintained at 20/62 at study conclusion at 60 weeks (1 year). At baseline, SD OCT mean central retinal thickness was 432 µm and improved to 294 µm at 60 weeks (P < 0.02). At the study conclusion, 42.5% of eyes (17/40) showed better than 20/50 BCVA, and only 5% of eyes (2/40) showed a BCVA worse than 20/200. In the every-6-weeks interval treatment arm, patients received 9 injections, whereas in the treat-and-adjust study arm, patients received 8.4 injections (P = 0.88, not significant). One patient experienced an inflammatory response after aflibercept injection, but this did not occur again for this patient, nor for any other study injections (1/400 injections [0.0025%]). No patients demonstrated endophthalmitis or metastatic disease or died during the study window. CONCLUSIONS: Aflibercept seems to limit vision loss associated with radiation maculopathy. In this randomized, prospective clinical study, no difference was found between a fixed 6-week treatment interval and a variable treat-and-adjust interval because virtually all patients required treatment every 6 weeks and were not able to extend. Remarkably, almost half of all treated patients maintained BCVA of 20/50 or better throughout 1 year of treatment. Aflibercept is effective in treating radiation maculopathy, but requires an ongoing treatment approach.

RESUMEN

A retrospective analysis was performed of patients who received a paracentesis immediately following an intravitreal injection of bevacizumab or triamcinolone acetonide. These patients were previously diagnosed as having glaucoma, ocular hypertension, or had responded previously with sustained elevated intraocular pressure. Of 1661 procedures were performed. Totally 219 (13%) of the injections were on phakic patients. A median (SD) of 210 µL (40 µL) of aqueous was removed during each paracentesis. There were no reported incidences of any complications. We propose performing a paracentesis immediately following intravitreal injections for patients at risk for ocular hypertension, glaucoma, and retinal vein or artery occlusion.

RESUMEN

BACKGROUND: Retinoblastoma is considered the most common intraocular malignancy in childhood, comprising 4% of all pediatric cancers. Management of retinoblastoma has evolved over the past two decades and intra-ophthalmic artery chemotherapy has emerged as a new modality of globe-conserving treatment with excellent results. This treatment achieves effective tumor reduction by delivering localized chemotherapy, decreases enucleation rate, and minimizes systemic and local side effects. CASE PRESENTATION: We report the case of an 8-year-old girl with a late presentation of an advanced unilateral retinoblastoma associated to diffuse exudative retinal detachment in the right eye, classified as group E by the International Classification of Retinoblastoma. The initial therapeutic proposal for the patient was five sessions of intra-ophthalmic artery chemotherapy (IAC) associated to large spot diode laser therapy. After undergoing four sessions of IAC, the fundus exam revealed a giant retinal tear associated to a total retinal detachment in the affected eye. The IAC treatment was concluded and enucleation was considered the best treatment option at that moment, since IAC was unable to control the tumor's activity and the patient's eye presented with a complex rhegmatogenous retinal detachment (RRD). However, family left for a second opinion and never returned. CONCLUSIONS: The usage of IAC for retinoblastoma management may lead to important local complications. Despite rare, RRD secondary to IAC may occur. We postulate that the giant tear observed in this case was caused by the rapid tumor necrosis using this route of treatment.

RESUMEN

Background. Optic disk melanocytoma is a primary tumor of the optic disk that represents a clinical diagnostic challenge due to its similarities with melanoma. Purpose. The authors present three cases in which genetic expression profiling was used to identify tumor prognosis of optic disk melanocytoma. Case Series. In two cases fine-needle aspiration biopsy was performed to obtain tissue through a transvitreal route into the apex of the tumor while the patient underwent pars plana vitrectomy, laser ablation, phacoemulsification with posterior chamber intraocular lens implantation, and intravitreal triamcinolone acetonide. In the other case the tissue was obtained after definite enucleation. Conclusion. Genetic expression profiling is a useful diagnostic tool for classification and can provide vital information to the ocular oncologist regarding prognosis.

RESUMEN

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.

RESUMEN

Recent advances in vitreoretinal surgical technology combined with advances in small-incision cataract surgery have enabled the ophthalmic surgeon to provide combined management of cataract and retinal pathology. Progressive understanding of the inevitability of cataract progression after pars plana vitrectomy along with the negative impact of early cataract progression on visual acuity outcomes have defined the importance of combined cataract surgery and pars plana vitrectomy in improving surgical outcomes. Combining phacoemulsification with intraocular lens placement with vitrectomy has now been shown to decrease visual rehabilitation time in patients with early/visually significant cataracts. These benefits are especially apparent when complex ocular pathology is present and clear visualization during surgery is needed. This report focuses on specific factors pertaining to combined surgery that include patient selection, mechanics of phacovitrectomy, and potential complications. The authors report that utilization of combined phacovitrectomy at their institution has had an outstanding success rate with 95% of the patients achieving 2-line or greater improvements in visual acuity within 6 weeks of surgery. Combined phacovitrectomy is associated with a significant reduction in overall healthcare costs that may become more important in this era of healthcare reform. Finally, rapid adoption of combined phacovitrectomy has occurred internationally, but remains delayed at most institutions in the USA.

RESUMEN

The authors present three cases in which spectral-domain optical coherence tomography was used to identify fine-needle aspiration biopsy incision sites. These biopsies were performed to obtain tissue for gene expression profiling of choroidal tumors. A transvitreal route into the apex of the tumors was utilized for the biopsies while the patients underwent pars plana vitrectomy, membrane peel, laser ablation, phacoemulsification with posterior chamber intraocular lens implantation, and intravitreal triamcinolone acetonide. To the best of the authors' knowledge, this is the first report documenting fine-needle aspiration biopsy incision wound architecture of the posterior segment with optical coherence tomography.

RESUMEN

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.

RESUMEN

PURPOSE: Three rare cases of macular holes coexistent with posterior uveal melanoma are presented. The possible pathogenesis of a macular hole secondary to uveal melanoma growth is discussed, as well as strategies to treat uveal melanoma before attempting macular hole repair. CASE REPORT: Each patient from all three cases had a macular hole and uveal melanoma at the initial presentation. The macular holes were present before uveal melanoma treatment in cases 1 and 2. The patient in case 3 had already been treated elsewhere with iodine-125 plaque brachytherapy for her melanoma. It was not known if macular hole formation occurred before or after that treatment. Macular hole repair was performed in case 1, and the hole was successfully closed. CONCLUSIONS: To the best of the authors' knowledge, there are now only nine documented cases of macular holes accompanying posterior uveal melanoma. Successful macular hole repair may prove difficult because the melanoma must first be properly treated and then monitored carefully to establish tumor inactivity.

RESUMEN

BACKGROUND: Microincisional vitrectomy surgery (MIVS) is the current standard surgical approach for pars plana vitrectomy. Historically, the most common surgical platform for vitrectomy surgery, since its introduction in 1997, has been the Accurus vitrectomy system. Recent introduction of the next generation of vitrectomy platforms has generated concerns associated with transitioning to new technology in the operating room environment. This study compared, in a matched fashion, surgical use of the Accurus vitrectomy system and the next generation Constellation Vision System to evaluate surgical efficiencies, complications, and user perceptions of this transition. METHODS: Electronic health records were abstracted as a hospital quality assurance activity and included all vitreoretinal surgical procedures at the Bascom Palmer Eye Institute, Anne Bates Leach Eye Hospital, during two discrete 12-month time periods. These two periods reflected dedicated usage of the Accurus (June 2008-May 2009) and Constellation Vision (July 2009-June 2010) systems. Data were limited to a single surgeon and evaluated for operating room (OR) total time usage/day, OR case time/case, and OR surgical time/case. Further analysis evaluated all patients undergoing combined MIVS and clear cornea phacoemulsification/intraocular lens (IOL) implantation during each individual time period to determine the impact of the instrumentation on these parameters. All records were evaluated for intraoperative complications. RESULTS: Five hundred and fourteen eligible patients underwent MIVS during the 2-year study windows, with 281 patients undergoing surgery with the Accurus system and 233 patients undergoing surgery with the Constellation system. Combined MIVS and phacoemulsification with IOL implantation was performed 141 times during this period with the Accurus and 158 times during the second study period with the Constellation. Total number of patients operated per day increased from 7.55 with Accurus to 8.53 with Constellation. Surgical room time decreased from 56 minutes with Accurus to 52 minutes with Constellation, and procedure time decreased from 35 minutes with Accurus to 31 minutes with Constellation (P < 0.004). Combined MIVS/phacoemulsification surgery saw similar declines in surgical room time and procedure time (P < 0.001). Subset analysis of procedures limited by case number per day (eg, four cases/day, five cases/day, six cases/day, and seven or more cases/day) showed similar outcomes with a decrease in surgical room time and procedure time. No increases in surgery-related complications were noted by quality assurance review during these time periods. DISCUSSION: Transitioning to advanced surgical technology is a complex issue for the surgeon, the hospital team, and the hospital administration. This study documents improvement in three significant measures of surgical efficiency: operative number of patients per day, operative room time, and surgical procedure time that reflect the positive impact of the novel, combined, integrated, posterior and anterior, ophthalmologic surgical platform of the Constellation Vision System. These data are imperative to evaluate the impact of transition from one surgical platform to another. During this transition, hospital quality assurance review and surgeon evaluation of operative complications showed no increased concerns for the shift from the Accurus to the Constellation Vision System surgical platform. Further, both operative staff and surgeons felt that the transition to the Constellation was not associated with increases in difficulty with setup, turnover, or use and that the Constellation decreased safety concerns for surgical usage. Ultimately, in this case, new technology benefited the surgeon, the patient, and the hospital.

RESUMEN

Objective. To investigate the efficacy of two different dosing strategies of radioactive iodine-125 ((125)I) in the management of small- and medium-sized posterior uveal melanoma. Patients and Methods. The medical records of consecutive patients with choroidal melanomas between 1.5 and 5.0 mm in apical height treated initially with (125)I plaque radiotherapy were reviewed. Patients were treated with one of the following two treatment dosing strategies: (1) 85 Gy to the apical height of the tumor (group 1) or (2) 85 Gy to a prescription point of 5.0 mm (group 2). Results. Of 95 patients, 55 patients were treated to the apical height of the tumor, and 40 were treated to a prescription point of 5.0 mm. Comparative analysis of the incidence rates of specific complications between the two groups demonstrates that group 2 had a significantly higher incidence of radiation retinopathy, radiation optic neuropathy, and/or visually significant cataract formation than group 1 (P = 0.028). Conclusion. Treatment of choroidal melanomas less than 5 mm in apical height with (125)I brachytherapy to the true apical height is equally effective when compared to treatment with 85 Gy to 5.0 mm. Treatment to the apical height of the tumor may result in lower incidence of radiation-related complications.

RESUMEN

PURPOSE: To document that with proper patient and procedure selection, children undergoing general inhalational anesthesia for ophthalmologic exams (with or without photos, ultrasound, laser treatment, peri-ocular injection of chemotherapy, suture removal, and/or replacement of ocular prosthesis) can be safely anesthetized without the use of an intravenous (IV) line. Children are rarely anesthetized without IV access placement. We performed a retrospective study to determine our incidence of IV access placement during examinations under anesthesia (EUA) and the incidence of adverse events that required intraoperative IV access placement. METHODS: Data collected from our operating room (OR) information system includes but is not limited to diagnosis, anesthesiologist, surgeon, and location of IV catheter (if applicable), patient's date of birth, actual procedure, and anesthesia/procedure times. We reviewed the OR and anesthetic records of children (>1 month and <10 years) who underwent EUAs between January 1, 2003 and May 31, 2009. We determined the percentage of children who were anesthetized without IV access placement, as well as the incidence of any adverse events that required IV access placement, intraoperatively. RESULTS: We analyzed data from 3196 procedures performed during a 77-month period. Patients' ages ranged from 1 month to 9 years. Overall, 92% of procedures were performed without IV access placement. Procedure duration ranged from 1-39 minutes. Reasons for IV access placement included parental preference for antinausea medication and/or attending preference for IV access placement. No child who underwent anesthesia without an IV line had an intraoperative adverse event requiring insertion of an IV line. CONCLUSION: Our data suggest that for children undergoing general anesthesia for ophthalmologic exams (with or without photos, ultrasound, laser treatment, intraocular injection of chemotherapy, suture removal, and/or replacement of ocular prosthesis), anesthesia can be safely conducted without placement of an IV line.
