PARACENTRAL ACUTE MIDDLE MACULOPATHY AS AN EARLY SIGN OF WALDENSTRÖM MACROGLOBULINEMIA.

PURPOSE: To report a case of paracentral acute middle maculopathy as the earliest sign of an undiagnosed, life-threatening hyperviscosity syndrome. METHODS: A 78-year-old man with an acute paracentral scotoma and examination findings of bilateral arteriolar tortuosity and unilateral paracentral acute middle maculopathy. RESULTS: Work-up revealed anemia and elevated serum viscosity. Protein electrophoresis demonstrated an immunoglobulin M kappa monoclonal protein spike, and bone marrow biopsy confirmed an immunoglobulin M gammopathy consistent with Waldenström macroglobulinemia. Systemic chemotherapy was initiated. CONCLUSION: This case demonstrates typical optical coherence tomography findings of paracentral acute middle maculopathy, which led to the diagnosis of a rare lymphoproliferative disorder. This highlights the importance of a prompt work-up for paracentral acute middle maculopathy to detect underlying systemic diseases, including hyperviscosity syndromes.

Rubella virus-associated necrotizing granulomatous inflammation with extensive eyelid, ocular, and orbital involvement.

We present a case of cutaneous granulomatous disease associated with rubella virus in a 4-year-old girl without an identifiable immunodeficiency. In this case, a combination of anti-inflammatory, anti-viral, and anti-neutrophil therapies successfully treated vision-threatening eyelid, conjunctival, scleral, and orbital inflammation.

Increased Number and Severity of Open Globe Injuries during COVID-19 Stay-at-home Orders.

PURPOSE: To evaluate the occurrence and outcome of open globe injury during state-mandated COVID-19 stay-at-home orders compared to historical averages at a tertiary medical center in Portland, Oregon. METHODS: Open globe injury between January 1, 2015 and December 31, 2020 was identified using relevant procedure codes. The number of injuries, mechanism of trauma, and short-term outcomes of globes repaired during the study period of March 23, 2020 to July 6, 2020 when stay-at-home orders were in effect were compared to a cohort from the same 15-week time frame in 2015-2019. We also evaluated injuries occurring throughout 2020 as compared to the prior 5 years. RESULTS: 263 consecutive open globe injuries were identified between January 2015 and December 2020. While Oregon's stay-at-home orders were in effect, we observed a significant increase in the number of open globe injuries treated compared to the prior 5 years (p = .004). Twenty-four cases identified during the study period represent a 2-fold increase over the 2015-2019 average of 11.8 globe repairs during the same 15-week time period. Visual acuity < 20/200 at 6 months (p = .008) and secondary enucleation (p < .001) were more frequent during stay-at-home orders, and severity of injury as calculated by the Ocular Trauma Scores (OTS) was higher. Time-to-repair was similar between the two cohorts. CONCLUSION: At our center, there was an increased number and severity of open globe injury during the period of mandatory COVID-19 stay-at-home orders. Visual acuity outcomes and risk for secondary enucleation were poorer compared to the reference cohort.Abbreviations: Ocular Trauma Score (OTS), Open globe injury (OGI), Emergency department (ED), Oregon Health and Science University (OHSU).

Membranous Encapsulation of an Akreos IOL Following Scleral Fixation masquerading as opacification.

PURPOSE: To report of case of membranous encapsulation of a scleral-fixated Akreos intraocular lens (IOL) that was successfully treated with vitrectomy and membranectomy without IOL exchange or removal. METHODS: Case report. PATIENT: A 58-year-old woman with a history of bilateral chronic anterior and intermediate uveitis underwent scleral fixation of Akreos IOL for dislocated 3-piece IOL in the vitreous cavity. She presented one year later with progressively worsening vision (decreased to 20/200) and was found to have a complete encapsulation of the IOL. RESULTS: The patient underwent successful vitrectomy and membranectomy with return of vision to 20/25 within three months of surgery. CONCLUSION: There are numerous case reports of opacification after scleral fixation of Akreos IOL. To our knowledge, this is the first report of complete encapsulation of the IOL with a membrane of this type and character. The etiology for this patient's presentation is unclear, but was presumed to be related to her history of chronic intraocular inflammation.

Electron Beam Irradiated Corneal Versus Gamma-Irradiated Scleral Patch Graft Erosion Rates in Glaucoma Drainage Device Surgery.

INTRODUCTION: Patch graft erosion and implant exposure is a known complication of glaucoma drainage device (GDD) surgery. Recently, electron beam (e-beam) irradiated corneal tissue ha s become available; however, limited data exist on the rates of erosion for e-beam irradiated corneal grafts compared to traditional scleral grafts after GDD surgery. METHODS: This retrospective study examines the records of 253 eyes from 225 adult subjects who underwent GDD surgery with either e-beam irradiated corneal or scleral grafts at the Casey Eye Institute by five surgeons between April 22, 2014 and October 11, 2017. Surgical procedures and the occurrence of graft erosion were determined using billing codes and verified by manual review of electronic health records. RESULTS: The average age at the time of surgery was 61.3 ± 17.5 years (n = 200) and 60.8 ± 16.8 years (n = 53) for the e-beam irradiated cornea and sclera groups, respectively. The average follow-up time post-surgery was 416 ± 345 days and 495 ± 343 days for the e-beam irradiated cornea and sclera groups, respectively. There were no statistically significant differences in sex, age, follow-up time, and glaucoma diagnosis between the groups; however, the e-beam irradiated cornea group was statistically more likely to have an Ahmed implant as compared to the sclera group. No erosion events were noted in either group. CONCLUSION: e-Beam irradiated corneal grafts were used 3.8 times more frequently relative to scleral grafts, yet there were no cases of graft erosion in either group during the follow-up period.

Evolution of Traumatic Parenchymal Intracranial Hematomas (ICHs): Comparison of Hematoma and Edema Components.

This study seeks to quantitatively assess evolution of traumatic ICHs over the first 24 h and investigate its relationship with functional outcome. Early expansion of traumatic intracranial hematoma (ICH) is common, but previous studies have focused on the high density (blood) component. Hemostatic therapies may increase the risk of peri-hematoma infarction and associated increased cytotoxic edema. Assessing the magnitude and evolution of ICH and edema represented by high and low density components on computerized tomography (CT) may be informative for designing therapies targeted at traumatic ICH. CT scans from participants in the COBRIT (Citicoline Brain Injury Trial) study were analyzed using MIPAV software. CT scans from patients with non-surgical intraparenchymal ICHs at presentation and approximately 24 h later (±12 h) were selected. Regions of high density and low density were quantitatively measured. The relationship between volumes of high and low density were compared to several outcome measures, including Glasgow Outcome Score-Extended (GOSE) and Disability Rating Score (DRS). Paired scans from 84 patients were analyzed. The median time between the first and second scan was 22.79 h (25%ile 20.11 h; 75%ile 27.49 h). Over this time frame, hematoma and edema volumes increased >50% in 34 (40%) and 46 (55%) respectively. The correlation between the two components was low (r = 0.39, p = 0.002). There was a weak correlation between change in edema volume and GOSE at 6 months (r = 0.268, p = 0.037), change in edema volume and DRS at 3 and 6 months (r = -0.248, p = 0.037 and r = 0.358, p = 0.005, respectively), change in edema volume and COWA at 6 months (r = 0.272, p = 0.049), and between final edema volume and COWA at 6 months (r = 0.302, p = 0.028). To conclude, both high density and low density components of traumatic ICHs expand significantly in the first 2 days after TBI. In our study, there does not appear to be a relationship between hematoma volume or hematoma expansion and functional outcome, while there is a weak relationship between edema expansion and functional outcome.
