IMPORTANCE: A unique pigmentary maculopathy was recently described in 6 patients with long-term exposure to pentosan polysulfate sodium (PPS), a long-standing oral therapy for interstitial cystitis. ...OBJECTIVE: To characterize the exposure characteristics and clinical manifestations of PPS–associated maculopathy. DESIGN, SETTING, AND PARTICIPANTS: In this multi-institutional case series, medical records of patients who exhibited the characteristic maculopathy in the setting of prior PPS exposure were retrospectively reviewed. Data were collected from August 1, 2012, to October 1, 2018, and data were analyzed from October 2018 to January 2019. MAIN OUTCOMES AND MEASURES: Drug exposure, visual acuity, and retinal imaging characteristics. RESULTS: Of the 35 included patients (70 eyes), 34 (97%) were female, and the median (range) age was 60 (37-79) years. The median (range) duration of PPS intake was 15 (3-22) years, and the median (range) cumulative exposure was 1.61 (0.44-4.31) kg. The leading visual symptoms were metamorphopsia, blurred vision, and prolonged dark adaptation. Median (range) logMAR visual acuity of all eyes was 0.10 (−0.12 to 1.18). Fundus examination often revealed hyperpigmented macular spots (34 of 64 eyes 53%) with interspersed pale-yellow deposits, although less commonly in eyes that exhibited retinal pigment epithelial atrophy (6 of 26 eyes 23%; P < .001). Optical coherence tomography showed foci of retinal pigment epithelium elevation or thickening associated with hyperreflectance on near-infrared reflectance imaging. Fundus autofluorescence imaging typically revealed a symmetric, confluent pattern of hyperautofluorescent and hypoautofluorescent spots that involved the fovea in all eyes and extended to the retinal periphery in 24 eyes (36%). Longitudinal evaluation demonstrated dynamic changes in pigmentary abnormalities. CONCLUSIONS AND RELEVANCE: These findings suggest that PPS–associated maculopathy is a vision-threatening condition that can manifest in the setting of long-term exposure to the drug. Multimodal imaging posits a distinctive clinical phenotype, characterized in this cohort by dynamic alterations within the retinal pigment epithelium and at the retinal pigment epithelium–photoreceptor interface. Ongoing work might explore causality and direct screening guidelines.
IMPORTANCE: The publication of the US Physician Payments Sunshine Act provides insight into the financial relationship between physicians and the pharmaceutical industry. This added transparency ...creates new opportunities of using objective data to better understand prior research that implicates pharmaceutical promotions as an important factor in a physician’s decision-making process. OBJECTIVE: To assess the association between reported industry payments and physician-prescribing habits by comparing the use of anti–vascular endothelial growth factor (VEGF) intravitreal injections by US ophthalmologists to the industry payments these same physicians received. DESIGN, SETTING, PARTICIPANTS: This study reviews data from the Centers for Medicare & Medicaid Services (CMS) 2013 Medicare Provider Utilization and Payment Data: Physician and Other Supplier Public Use File and the CMS-sponsored August through December 2013 Open Payments program (Physician Payments Sunshine Act). Ophthalmologists who prescribe anti-VEGF injections for all indications were analyzed. MAIN OUTCOMES AND MEASURES: Association between industry payments reportedly received and the number and type of anti-VEGF injections administered. RESULTS: A total of 3011 US ophthalmologists were reimbursed by CMS for 2.2 million anti-VEGF injections in 2013. Of these physicians, 38.0% reportedly received $1.3 million in industry payments for ranibizumab and aflibercept. Analysis revealed positive associations between increasing numbers of reported industry payments and total injection use (r = 0.24; 95% CI, 0.22-0.26; P < .001), aflibercept and ranibizumab injection use (r = 0.32; 95% CI, 0.29-0.34; P < .001), and percentage of injections per physician that were aflibercept or ranibizumab (r = 0.27; 95% CI, 0.25-0.29; P < .001). A smaller association was noted between greater number of industry payments and bevacizumab injection use (r = 0.07; 95% CI, 0.04-0.09; P < .001). Similar associations were found between the total dollars of reported industry payments received to injection use. Subgroup analysis further revealed that physicians receiving $1 to $25 in reported industry benefits were more likely than those not receiving industry payments to perform a greater percentage of their injections with aflibercept and ranibizumab. CONCLUSIONS AND RELEVANCE: Among ophthalmologists who prescribe anti-VEGF medications, there is a positive association between reported pharmaceutical payments and increased use of aflibercept and ranibizumab injections. As is inherent to the design of correlation studies, this analysis cannot determine whether the payments reported caused the increased use, are a result of the increased use, or are merely associated with some other factor that causes the increased use.
To evaluate visual outcomes after vitrectomy for intraocular hemorrhages secondary to traumatic brain injury.
Retrospective, observational case series.
A total of 28 eyes in 20 patients undergoing ...vitrectomy for Terson syndrome secondary to traumatic brain injury between 1997 and 2015.
We reviewed the records of patients undergoing a standard 20-gauge or 23-gauge pars plana vitrectomy for intraocular hemorrhages secondary to traumatic brain injury, and the timing of vitrectomy in relation to the inciting intracranial event was recorded.
The primary outcome measure was the change in the preoperative visual acuity score at postoperative month 1 and at the last noted clinic appointment.
A total of 28 eyes in 20 patients (all male) underwent pars plana vitrectomy for intraocular hemorrhages secondary to traumatic brain injury. The mean preoperative baseline logarithm of the minimum angle of resolution (logMAR) (Snellen) best-corrected visual acuity (BCVA) was 1.81±0.56 (20/1290). At 1-month postoperative follow-up, the mean BCVA was 0.30±0.33 (20/40). At the date of the last follow-up, the mean BCVA was 0.15±0.24 (20/30) and the median BCVA was 0.00 (20/20). Although the difference between preoperative and postoperative BVCA was significantly different at 1 month and the final postoperative clinic visits (P < 0.001), there was not a correlation between preoperative visual acuity as a predictor of final postoperative visual acuity outcome (r=-0.32; P = 0.09; 95% confidence interval CI -0.62 - 0.06). At the date of the last follow-up, the differences in visual outcomes between the individuals undergoing vitrectomy within 3 months of the inciting event, 0.08±0.15 (20/25), were not significantly different than those undergoing surgical intervention after 3 months, 0.18±0.27 (20/30) (P = 0.28). Three cases among those undergoing vitrectomy after 3 months were complicated by retinal detachment, none of which resulted in a BCVA worse than when the patient originally presented preoperatively.
In this retrospective series of patients without other ocular pathology, surgical intervention effectively provided rapid visual recovery in the majority of individuals with intraocular hemorrhages secondary to traumatic brain injury, irrespective of the timing of vitrectomy or of preoperative visual acuity.
To compare and contrast the manifestations and surgical management of subglottic stenosis in patients with airway obstruction attributed to granulomatosis with polyangiitis (GPA), previously known as ...Wegener granulomatosis, and those with idiopathic subglottic stenosis (iSGS).
Retrospective medical chart review. Review of subglottic stenosis cases seen in the otolaryngology department of an academic medical center from 2005 through 2010. Data were obtained on disease presentation, operative management. and findings.
Tertiary referral center.
A total of 24 patients with iSGS and 15 patients with GPA-associated subglottic stenosis (GPA-SGS).
All individuals with iSGS were female, and 40% of patients with GPA-SGS were male (P < .01). Patients with iSGS tended to have a higher Myer-Cotton stenosis grade at the time of dilation than those with GPA-SGS (P = .02). Individuals with GPA-SGS were more likely to undergo tracheotomy as a result of disease-related complications than individuals with iSGS (P < .01). No patients with an open airway reconstruction in the iSGS group required follow-up mechanical dilation. In contrast, all patients with open airway reconstructions in the GPA-SGS group underwent more than 1 subsequent airway dilation (P < .01).
While surgical utilization is the mainstay of treatment in iSGS and GPA-SGS, iSGS occurs almost exclusively in females and presents with a greater degree of stenosis at the time of endoscopic dilation. In contrast, GPA-SGS is associated with greater rates of tracheotomy. Open airway reconstruction may be used in the treatment of iSGS and GPA-SGS but is much more effective in iSGS.
Objectives/Hypothesis:
To describe the otolaryngologic presentation and natural history of granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis, and to compare ...otolaryngologic outcomes of patients with systemic GPA to those with a limited form of GPA confined to the head and neck.
Study Design:
Retrospective chart review.
Methods:
Review of GPA cases (identified by serology, biopsy, or clinical presentation) seen in the otolaryngology department of an academic medical center.
Results:
A total of 24 patients were identified; each patient was followed for an average 6.8 years. Sinusitis and subglottic stenosis were the most commonly observed head and neck manifestations at diagnosis, seen in 64% and 36%, respectively. Over time, disease spread to additional sites in more than half the cohort (n = 14), but only two of 13 patients with disease initially limited to the head and neck developed pulmonary disease, and none developed renal disease. Cumulatively, otitis media was more likely to be observed in patients with systemic disease (P = .04). Patients with localized (n = 12) and systemic (n = 12) GPA did not have significantly different rates of surgical interventions (0.55 vs. 0.72 surgical interventions/patient‐year of follow‐up, respectively, P = .19).
Conclusions:
GPA has a variety of head and neck manifestations, most commonly sinusitis, nasal disease, subglottic stenosis, and otitis media. GPA commonly progresses to involve additional sites, regardless of the extent of disease. These patients require frequent surgical intervention, and the clinician should remain vigilant for progression of disease.
Abstract Purpose To report the case of an adult female who presented on different occasions with recurrent uveitis provoked by initiating therapy of two recently approved agents, dabrafenib and ...pembrolizumab, for treatment of metastatic melanoma. Observations A 61 year old female presented with bilateral anterior uveitis after initiating therapy with dabrafenib for advanced metastatic melanoma. Her symptoms resolved and exam improved with oral and topical steroid therapy. Months later, she was started on pembrolizumab and transitioned off dabrafenib. Within days of starting pembrolizumab, she developed recurrent bilateral uveitis. This responded to escalating doses of topical and oral corticosteroid therapy and resolved following discontinuation of pembrolizumab. Nine months later, our patient received her third dose of pembrolizumab due to further progression of melanoma and within three days developed blurry vision, photophobia and subsequent ophthalmologic exam demonstrated bilateral panuveitis. Conclusions and importance Dabrafenib and pembrolizumab therapy have both previously been associated with uveitis. Here, we document a case of a woman who developed acute uveitis in response to beginning therapy with dabrafenib and then later developed acute uveitis soon after initiating pembrolizumab. To our knowledge, this is the first time this uncommon side-effect has been reported in the same patient after receiving sequential targeted agents and checkpoint inhibitors.
To report the case of an adolescent male with a history of Best macular dystrophy and retinal astrocytic hamartoma.
A 15 year old male with a history of Best macular dystrophy who had been followed ...by ophthalmology for 9 years was noted to have progressive enlargement of a superonasal peripapillary retinal lesion. Imaging and exam are consistent with a diagnosis of retinal astrocytic hamartoma. There were no extraocular signs or symptoms that were diagnostic of a phakamatosis. Genetic testing was positive for a mutation in
, but not

Retinal astrocytic hamartoma is an unusual association with Best macular dystrophy, and this case highlights the balanced approach needed to navigate a potentially complex work-up.
Owing to the global epidemic of obesity, the incidence of diabetes and its complications are rapidly increasing around the world. Yet, visual impairment caused by diabetic retinopathy is ...paradoxically on the decline. This improvement is due to better understanding of etiologic mechanisms, increased screening, and advent of newer therapies. Here, we discuss salient developments in the comprehension of the root causes of diabetic retinopathy and the molecular mechanisms underlying current treatment approaches.
To report on the microbiology, management, and visual outcomes of intravitreal injection (IVI)-associated, culture-proven endophthalmitis.
All patients seen at a tertiary referral center with ...culture-proven endophthalmitis associated with an IVI between June 2007 and July 2017 were included in this retrospective analysis.
Thirty-five patients with culture-positive endophthalmitis following IVI were identified. All gram-positive organisms (34 of 35) were susceptible to vancomycin. Cases due to pathogens associated with oral or respiratory flora were common (31.4%, n = 11), presented earlier (2.0 days vs. 4.6 days, P < .001), were more likely to undergo pars plana vitrectomy (81.8% vs. 25.0%, P = .002) and had worse visual acuity outcomes.
IVI-associated endophthalmitis pathogens and anti-microbial susceptibilities in the Pacific Northwest are similar to those reported from other geographic locations. Bacteria associated with the oral and respiratory flora are common isolates that result in a more aggressive course and worse visual outcomes. Ophthalmic Surg Lasers Imaging Retina. 2019;50:33-38..
Summary
Background
Through its powerful immunoregulatory effects, infection with atypical mycobacteria may exert a protective effect on the development of childhood allergic disease.
Objective
To ...examine the relationship between childhood atopy or allergic disease and previous infection with four species of atypical mycobacteria.
Methods
Eight hundred and six children aged 8–18 years and living in rural Crete – most of whom had had previous BCG immunization – underwent skin prick testing with 10 aeroallergens; their parents completed a standardized questionnaire relating to allergic disease. No less than 8 weeks later each child underwent intradermal skin tests with 0.1 mL solutions of four selected mycobacterial reagents (Aviumin C, Gordonin, Chelonin and Ranin I).
Results
Twenty‐three percent of children were atopic on skin prick testing; far fewer had symptoms of asthma (5%) or hayfever in conjunction with a positive prick test to pollens (2%). Eighty percent of children had positive skin responses to one or more mycobacterial species. Among all children – and those with a BCG scar – there was no association between atopy or allergic symptoms and mycobacterial skin responses; among the few children without a BCG scar however those with positive mycobacterial responses were less likely to be atopic or to report allergic symptoms; these differences were not statistically significant.
Conclusions
Our findings, in a population of BCG‐immunized children, do not lend support to the suggestion that infection with atypical mycobacteria is protective against childhood allergic disease.
