Abstract

Purpose Explore the spectrum of clinical manifestations of pentosan polysulfate sodium (PPS) maculopathy observed across a range of practice settings. Design Multi-institutional retrospective study. Participants Patients exhibiting findings suggestive of PPS maculopathy identified from April 30, 2019, to December 4, 2020. Methods Members of the Macula Society submitted cases of presumed PPS maculopathy for consideration in this series. Diagnosis was confirmed by masked review of fundus imaging. Clinical characteristics of confirmed cases were summarized with descriptive statistics. Main Outcome Measures Pentosan polysulfate exposure characteristics and fundus imaging features. Results There were 74 patients with PPS maculopathy included in the current study. Median (interquartile range) age at diagnosis was 62.0 years (56.0–65.8). The median duration of exposure to PPS was 14.0 years (10.2–18.9), with a median cumulative exposure of 1.5 kg (0.9–2.4). The most common presenting symptom was decreased or blurry vision (66.2%), followed by prolonged dark adaption or nyctalopia (32.4%). The most common referral diagnosis was age-related macular degeneration (54.1%); 16.2% of patients were referred for suspected PPS maculopathy. Novel imaging findings emerged, including highly asymmetric disease in 2 patients and a prominent vitelliform maculopathy in 2 patients. Conclusions Most patients with PPS maculopathy exhibit characteristic findings on multimodal fundus imaging in the setting of high cumulative exposure to the oral drug. Some patients in the current study manifested novel imaging findings, expanding our understanding of the phenotypic spectrum of this condition. We recommend considering standardized ophthalmic screening of patients treated with PPS.

Abstract

PURPOSE: Assess systemic vascular endothelial growth factor-A (VEGF) levels after treatment with intravitreous aflibercept, bevacizumab or ranibizumab. DESIGN: Comparative-effectiveness trial with participants randomly assigned to 2-mg aflibercept, 1.25-mg bevacizumab, or 0.3-mg ranibizumab following a retreatment algorithm. PARTICIPANTS: Participants with available plasma samples (N=436) METHODS: Plasma samples were collected before injections at baseline, 4-week, 52-week and 104-week visits. In a pre-planned secondary analysis, systemic free-VEGF levels from an ELISA immunoassay were compared across anti-VEGF agents and correlated with systemic side effects. MAIN OUTCOME MEASURES: Changes in the natural log (ln) of plasma VEGF levels. RESULTS: Baseline free-VEGF levels were similar across all 3 groups. At 4 weeks, mean ln(VEGF) changes were −0.30±0.61, −0.31±0.54, −0.02±0.44 pg/ml for the aflibercept, bevacizumab, and ranibizumab groups, respectively. The adjusted differences between treatment groups (adjusted CI; P-value) were −0.01 (−0.12, +0.10; P=0.89), −0.31 (−0.44, −0.18; P

Abstract

Purpose It is our impression that there is substantial, unexplained variation in hand surgeon recommendations for treatment of peripheral mononeuropathy. We tested the null hypothesis that specific patient and provider factors do not influence recommendations for surgery. Methods Using a web-based survey, hand surgeons recommended surgical or nonsurgical treatment for patients in 2 different scenarios. Six elements of the first scenario (symptoms, circumstances, mindset, diagnosis, objective testing, and expectations) had 2 possibilities that were each independently and randomly assigned to each rater. For the second scenario, 2 different scenarios were randomly assigned to each rater. Multivariable logistic regression sought factors associated with a recommendation for surgery. Results A total of 186 surgeons of the Science of Variation Group completed a survey regarding recommendation of surgery for 2 different patients based on clinical scenarios. Recommendations for surgery did not vary significantly according to provider characteristics. For the various elements in scenario 1, recommendation for surgery was more likely for patients who were self-employed and continued to work and who had objective electrodiagnostic abnormalities. For the 2 vignettes used in scenario 2, a recommendation for surgery was associated with abnormal electrophysiology. Conclusions The findings of this study suggest that—at least in a survey setting—surgeons prefer to offer peripheral nerve decompression to patients with abnormal electrophysiology, particularly those with effective coping strategies. Clinical relevance The role of objective verification of pathophysiology is debated, but it is an influential factor in recommendations for hand surgery.

Abstract

Purpose To address the factors that surgeons use to decide between 2 options for treatment when the evidence is inconclusive. Methods We tested the null hypothesis that the factors surgeons use do not vary by training, demographics, and practice. A total of 337 surgeons rated the importance of 7 factors when deciding between treatment and following the natural history of the disease and 12 factors when deciding between 2 operative treatments using a 5-point Likert scale between "very important" and "very unimportant." Results According to the percentages of statements rated very important or somewhat important, the most popular factors influencing recommendations when evidence is inconclusive between treatment and following the natural course of the illness were "works in my hands," "familiarity with the treatment," and "what my mentor taught me." The most important factors when evidence shows no difference between 2 surgeries were "fewer complications," "quicker recovery," "burns fewer bridges," "works in my hands" and "familiarity with the procedure." Europeans rated "works in my hands" and "cheapest/most resourceful" of significantly greater importance and "what others are doing," "highest reimbursement," and "shorter procedure" of significantly lower importance than surgeons in the United States. Observers with fewer than 10 years in independent practice rated "what my mentor taught me," "what others are doing" and "highest reimbursement" of significantly lower importance compared to observers with 10 or more years in independent practice. Conclusions Surgeons deciding between 2 treatment options, when the evidence is inconclusive, fall back to factors that relate to their perspective and reflect their culture and circumstances, more so than factors related to the patient's perspective, although this may be different for younger surgeons. Clinical relevance Hand surgeons might benefit from consensus fallback preferences when evidence is inconclusive. It is possible that falling back to personal comfort makes us vulnerable to unhelpful commercial and societal influences.

Abstract

The effect of grip on ulnar variance was evaluated in 66 symptom-free wrists of 53 volunteers. Zero-rotation posteroanterior x-ray films were taken of each wrist before and after exertion of a grip force measured with a Jamar dynamometer. The volunteers were randomly divided into two groups. Group I subjects (35 wrists) were asked to exert a constant grip force of 11.3 kg. Group II subjects (31 wrists) were asked to exert a maximum grip effort, which resulted in a mean grip force of 30 kg (range, 22.8 kg to 53.6 kg). Group I demonstrated a mean increase in ulnar variance of 1.27 mm and group II showed a mean increase of 1.95 mm. The minimum increase in ulnar variance observed was 0.25 mm. The changes observed were statistically significant. The results confirm that a relative increase in ulnar variance occurs with grip. There may be an etiologic role for daily activities that involve repetitive grip and forearm rotation in development of the ulnar impaction syndrome.

Abstract

We sent questionnaires to 424 retina specialists in order to compile information on the use of fluorescein angiography in pregnant women. Four-hundred and three specialists responded. Of these, 313 (78%) had never performed fluorescein angiography on a pregnant woman. Ninety specialists (22%) had performed at least one fluorescein angiogram on a pregnant woman; detailed information was obtained on 105 patients. Authors of previous reports that included fluorescein angiography during pregnancy provided information on an additional 11 patients. Substantiated side effects were nausea and/or vomiting in seven patients. Anomalies at birth, an undescended testicle and syndactyly, were reported in two children. There was one stillbirth with pathologic findings classic for toxemia and one fetal death not related in time to fluorescein angiography. One therapeutic abortion was performed for complications in toxemia. One spontaneous abortion occurred 3 days after fluorescein angiography in a patient who was four weeks pregnant. Eight children born to toxemic mothers had low birth weights. Based on our data, we conclude that fluorescein angiography does not offer a high rate of birth anomalies or complications during pregnancy.

Abstract

We sent 424 retina specialists questionnaires on fluorescein angiography performed on pregnant women; 399 specialists responded. Of these, 309 (77%) had never performed fluorescein angiography on a pregnant woman. Ninety specialists (23%) had performed at least one fluorescein angiogram on a pregnant woman; detailed information was obtained on 105 patients. Authors of previous reports that included fluorescein angiography during pregnancy provided information about an additional 11 patients. Substantiated side effects were nausea or vomiting in seven patients. Anomalies at birth, an undescended testicle and syndactyly, were reported in two children. There was one stillbirth with pathologic findings classic for toxemia, and one fetal death occurred several months after fluorescein angiography. One therapeutic abortion was performed for complications in toxemia. One spontaneous abortion occurred three days after fluorescein angiography in a patient who was four weeks pregnant. Eight children born to toxemic mothers had low birth weights. We conclude that fluorescein angiography does not cause a high rate of birth anomalies or complications during pregnancy.

Abstract

We reviewed ten patients who had posterior segment complications of acquired syphilis. Five of these patients had a neovascular membrane of the choroid associated with secondary or tertiary syphilis. Vision was stabilized after laser photocoagulation in one patient who had a choroidal neovascular membrane. Five additional patients had ocular manifestations including uveitis, optic neuritis, neuroretinitis, chorioretinitis, retinal hemorrhages, arterial and venous occlusion, vasculitis, and retinitis. Treatment of chorioretinal complications of syphilis with intravenous penicillin, if initiated early in the course of the disease, may result in excellent visual recovery.

Abstract

Purpose To examine the time burden of managing neovascular age-related macular degeneration (AMD) imposed on physicians, staff, patients, and caregivers. Design Mixed-methods, prospective, observational time-and-motion study. Methods The multicenter study was conducted from March 2011 through August 2012. Retina specialists administering ≥50 vascular endothelial growth factor (VEGF)–inhibitor injections monthly were surveyed and completed records for ≥5 patients scheduled for office visits within 3 weeks for anti-VEGF injection or monitoring. A survey was administered to 75 neovascular AMD patients aged ≥50 years who received ≥1 anti-VEGF injection in the past 6 months. Telephone interviews were conducted with 13 neovascular AMD patient caregivers. Results Fifty-six physicians provided data for 221 patients with neovascular AMD. Patients accounted for 20% of the health care staff's time per week, with an average of 23 staff members. An average patient visit for neovascular AMD was 90 minutes (range: 13 minutes to >4 hours). Patients reported an average time per visit of almost 12 hours, including preappointment preparation (16 minutes), travel (66 minutes), waiting time (37 minutes), treatment time (43 minutes), and postappointment recovery (9 hours). Patients stated that caregivers took time away from work (22%) and personal activities (28%) to provide transportation to appointments. Conclusions Neovascular AMD management imposes a substantial time burden on physicians, staff, patients, and caregivers. There may be a need for additional support and/or reimbursement for services required by patients and caregivers and provided by physicians.
