RESUMO

OBJECTIVES: Preeclampsia (PE) is a severe complication of pregnancy characterized by hypertension, proteinuria and compromised fetal blood supply. The eye, like other end organs, is affected by this systemic condition, but unlike in other organs, ocular media transparency allows high-resolution optical visualization of the vascular structure of the retina. Our aim was to assess how ultrasound-determined ocular blood-flow correlates with vascular structure of the retina and choriocapillaris determined by optical coherence tomography angiography (OCTA). METHODS: Plane-wave ultrasound and OCTA were performed on both eyes of 40 consecutive subjects consisting of normal controls (n = 11), mild PE (n = 5), severe PE (n = 17) and chronic or gestational hypertension (n = 7) within 72 hours following delivery. From ultrasound, we measured pulsatile flow velocity and resistance indices in the central retinal artery (CRA) and vein, the short posterior ciliary arteries (SPCAs) and choroid. From OCTA, we measured vascular density (VD) in the superficial, deep retina and choriocapillaris. We determined differences in Doppler and OCTA parameters among groups and correlations between ultrasound and OCTA. RESULTS: In severe PE, flow resistance was reduced with respect to controls. Flow velocity and resistance in the and SPCA were moderately correlated with VD in the choriocapillaris and peripapillary retina, but VD in PE did not differ significantly from controls. CONCLUSIONS: Although OCTA parameters were moderately correlated with Doppler ultrasound, OCTA did not demonstrate significant differences between PE and controls postpartum.

RESUMO

A 79-year-old male was hospitalized for respiratory failure secondary to coronavirus disease 2019 pneumonia. Approximately 6 hours after initiating proning, left globe subluxation with darkening of the superior sclera consistent with tache noir was noted. The left globe was thought to be hypotonus secondary to ciliary body shut down after a prolonged period of high intraocular pressure. The globe was reduced in the supine position with gentle traction of the eyelids. Over the next 24 hours, the left intraocular pressure improved to 10 mm Hg, and the tache-noir de la sclérotique resolved. The authors report the first known case of globe subluxation secondary to proning.

RESUMO

Purpose: To evaluate efficacy of a novel risk stratification system in minimizing resident surgical complications and to evaluate whether the system could be used to safely introduce cataract surgery to earlier levels of training. Materials and Methods: This is a retrospective cross-sectional study on 530 non-consecutive cataract cases performed by residents at Columbia University. Risk scores, preoperative best corrected visual acuity (BCVA), intraoperative complications, postoperative day 1 (POD1), and month 1 (POM1) exam findings were tabulated. The relationship between risk scores and POD1 and POM1 BCVA was modeled using linear regression. The relationship between risk scores and complication rates was modeled using logistic regression. Logistic regression was used to model the rates of complications across different levels of training. Rates of complications were compared between diabetic versus non-diabetic patients using t-tests. Results: Risk scores did not have significant association with intraoperative complications. Risk scores were predictive of corneal edema (OR = 1.36, p = 0.0032) and having any POM1 complication (OR = 1.20, p = 0.034). Risk scores were predictive of POD1 (ß = 0.13, p < 0.0001) and POM1 (ß = 0.057, p = 0.00048) visual acuity. There was no significant association between level of training and rates of intraoperative (p = 0.9) or postoperative complications (p = 0.06). Rates of intraoperative complication trended higher among diabetic patients but was not statistically significant (p = 0.2). Conclusion: Higher risk scores were predictive of prolonged corneal edema but not risk of intraoperative complications. Our risk stratification system allowed us to safely introduce earlier phacoemulsification surgery.

RESUMO

PURPOSE: To compare the rates of visual field (VF) progression between individuals of Black and White race and to investigate whether treatment effects may help explain differences previously reported between racial groups. DESIGN: Multicenter prospective observational cohort study. METHODS: Participants were patients in referral tertiary care glaucoma clinics with open angle glaucoma. Eyes were excluded who had <5 VF tests and <2 years of follow-up or any disease that could affect the optic nerve or the VF. The VF mean deviation (MD) slopes over time (dB/y) were calculated with linear regression models. Socioeconomic variables, rates of glaucoma surgery, medications, treated intraocular pressure (IOP), and central corneal thickness (CCT) were investigated. RESULTS: A total of 516 eyes were included with a mean (95% CI) follow-up time of 11.0 (range, 10.5-11.5) years and 15.0 (range, 14.1-15.8) visits. Participants of Black race were significantly younger (59.7 vs 66.9 years, P < .01) than those of White race. The mean CCT and socioeconomic variables were similar between Black and White groups (P = 0.20 and P = .56, respectively), as were treatment with topical medications (P = .90) and the rate of VF MD change (-0.24 [-0.31 to -0.17] dB/year vs -0.32 [-0.36 to -0.27], P = .11), despite higher treated mean IOP (14.9 [14.5 to 15.4] vs 14.0 [13.6 to 14.4] mm Hg, P = .03) and fewer trabeculectomies (29.5% vs 50.0%, P < .01) in the Black race group. CONCLUSIONS: Rates of VF progression were similar despite higher treated IOP in the Black race group. Mitigation of health access disparities in this study may have equalized previously reported different rates of VF progression between racial groups.

RESUMO

PURPOSE: The temporary cessation and profound changes in ophthalmic care delivery that occurred as a result of the coronavirus disease 2019 (COVID-19) pandemic have yet to be fully understood. Our objective is to assess patients' self-reported impact of health care lockdown measures on their fears and anxieties during the crisis period of the COVID-19 pandemic in New York City. METHODS: We conducted a digital, self-reported, patient care survey distributed by an e-mail at Columbia University's Department of Ophthalmology outpatient faculty practice. Inclusion criteria were age greater than or equal to 18 years, a diagnosis of either retinal disease or glaucoma, and a canceled or rescheduled ophthalmology established patient appointment during the acute phase of the COVID-19 pandemic in New York City. Patients without an e-mail address listed in their electronic medical records were excluded. The survey occurred between March 2, 2020, to May 30, 2020. Primary measures were survey responses to assess key areas of patient anxiety or concern during the pandemic including the safety of care delivery in a COVID pandemic, difficulties contacting or being seen by their ophthalmologist, concern of vision loss or disease progression, and concern over missed or access to treatments. Secondary measures were correlating survey response to factors such as visual acuity, intraocular pressure, diagnosis, disease severity, follow-up urgency, recent treatments, and diagnostic testing data. RESULTS: Of the 2594 surveys sent out, 510 (19.66%) were completed. Over 95% of patients were at least as concerned as in normal circumstances about their ocular health during the peak of the pandemic. Overall, 76% of respondents were more concerned than normal that they could not be seen by their ophthalmologist soon enough. Increased concern over ocular health, disease progression, and access to care all showed positive correlations (P<0.05) with worse disease severity as measured with testing such as visual fields and optical coherence tomography. In addition, 55% of patients were afraid of contracting COVID-19 during an office visit. CONCLUSION AND RELEVANCE: We found a majority of our patients were concerned about limitations in access to ophthalmic care and were fearful of disease progression. In addition, we found a number of demographic and clinical factors that correlated with increased anxiety in our patients.

RESUMO

Hemangiopericytomas and solitary fibrous tumors are uncommon neoplasms found in many locations, including the orbit. Both mesenchymal neoplasms share several clinicopathologic features, thus prompting intense debate as to whether they are variants of the same entity or merit separate designations in the orbit. These 2 entities, with the addition of giant cell angiofibroma of orbit, are of benign- to uncertain-behavior, CD34-positive, collagen-rich, specialized fibroblastic tumors, which may have overlapping or histologically identical features. In addition, so-called fibrous histiocytoma of orbit, a previous designation, has overlapping morphologic features with these tumors. To date, a large series of these collagen-rich fibroblastic tumors of the orbit has not been fully explored. Forty-one fibroblastic orbital tumors, originally diagnosed as hemangiopericytomas (n = 16), fibrous histiocytomas (n = 9), mixed tumors (hemangiopericytomas/fibrous histiocytoma) (n = 14), and giant cell angiofibromas of orbit (n = 2) between 1970 and 2009, were retrieved from our consultation files, the Ophthalmic Registry, at the Armed Forces Institute of Pathology. Slides and clinical records were reviewed, analyzed, and compared. Immunochemistry was performed for CD34, CD99, Bcl-2, Ki-67, and p53. Upon histologic review, all cases were reclassified as solitary fibrous tumor (41/41). The patients included 23 (56%) males, 17 (41%) females, and 1 unknown, with a mean age at presentation of 40.7 years (range, 16-70 years). The sites of involvement were the right orbit in 18 (44%) cases and the left in 16 (39%) cases. Tumors ranged in size from 0.4 to 5.0 cm (mean, 2.2 cm). Seventeen (41%) patients presented with an orbital mass, 8 (20%) with proptosis, 2 (5%) with painful mass, and 2 (5%) with painless mass. Duration of symptoms ranged from 3 to 96 months, with a mean of 23 months (median, 9 months). Microscopically, all lesions showed considerable similarity, varying in degree of cellularity, stromal collagen, and the presence of giant cells. Overlapping features with soft tissue giant cell fibroblastoma were observed. Immunochemistry revealed positivity for CD34 in all cases (100%), p53 in 85%, CD99 in 67.5%, and Bcl-2 in 47.5%. Although Ki-67 labeling was seen in all cases, it ranged from less than 1% in 54.3% of cases to 5% to 10% in 20% of cases. Taken together, the findings of this study suggest that orbital hemangiopericytoma and some cases previously designated as fibrous histiocytoma, giant cell angiofibroma of orbit, and solitary fibrous tumor have overlapping morphologic and immunohistochemical features and should be designated as solitary fibrous tumor. Adipocytes and unusual multivacuolated adipocytic cells may be present in these tumors, as well stromal myxoid change; and even stromal intramembranous ossification can be observed. There are overlapping features of orbital solitary fibrous tumor with another CD34-positive specialized fibroblastic tumor of soft tissue, giant cell fibroblastoma. Morphologic criteria for uncertain behavior to low-grade malignant ocular solitary fibrous tumors can be made by cytologic atypia and increased mitotic activity, but overall outcome for malignant solitary fibrous tumors of the eye should be further explored.
