Antibiotic utilization in endoscopic dacryocystorhinostomy: a multi-institutional study and review of the literature.

PURPOSE: Utilization of antibiotics for endoscopic dacryocystorhinostomy (endo-DCR) is largely dependent on individual surgeon preference. This study aimed to investigate prescribing practices of pre-, peri-, and postoperative antibiotics and effects on postoperative infection rates in patients who underwent endo-DCR. METHODS: A retrospective chart review of institutional data at two academic centers of endo-DCR cases from 2015-2020 was performed. Postoperative infection rates for patients who received pre-, peri-, and postoperative antibiotics, individually or in combination, and those who did not, were compared via odds ratio and ANOVA linear regression. RESULTS: 331 endo-DCR cases were included; 22 cases (6.6%) had a postoperative infection. There was no significant difference in the infection rates between patients without an active preoperative dacryocystitis who received different permutations of peri- and postoperative antibiotics. Patients who received preoperative antibiotics within two weeks of surgery for preexisting acute dacryocystitis, but did not receive peri- or postoperative antibiotics, had a higher rate of postoperative infections (p = 008). CONCLUSIONS: Our data suggest antibiotics may be beneficial only when patients have a recent or active dacryocystitis prior to surgery. Otherwise, our data do not support the routine use of antibiotic prophylaxis in endo-DCR.

Diverse Research Teams and Underrepresented Groups in Clinical Studies.

Importance: Several ophthalmic diseases disproportionately affect racial and ethnic minority patients, yet most clinical trials struggle to enroll cohorts that are demographically representative of disease burden; some barriers to recruitment include time and transportation, language and cultural differences, and fear and mistrust of research due to historical abuses. Incorporating diversity within the research team has been proposed as a method to increase trust and improve engagement among potential study participants. Objective: To examine how demographic factors of potential research participants and personnel may be associated with patient consent rates to participate in prospective ophthalmic clinical studies. Design, Setting, and Participants: This retrospective cohort study included patients from an urban, academic hospital who were approached for consent to participate in prospective ophthalmic clinical studies conducted between January 2015 and December 2021. Main Outcomes and Measures: Multivariable logistic regression assessing associations between patient and research personnel demographics and rates of affirmative consent to participate was used. Results: In total, 1380 patients (mean [SD] age, 58.6 [14.9] years; 50.3% male) who were approached for consent to participate in 10 prospective ophthalmic clinical studies were included. Of prospective patients, 566 (43.5%) were Black; 327 (25.1%), Hispanic or Latino; 373 (28.6%), White; 36 (2.8%), other race and ethnicity; and 78 (5.8%) declined to answer. Black patients (odds ratio [OR], 0.32; 95% CI, 0.24-0.44; P < .001) and Hispanic or Latino patients (OR, 0.31; 95% CI, 0.20-0.47; P < .001) were less likely to consent compared with White patients. Patients with lower socioeconomic status were less likely to consent than patients with higher socioeconomic status (OR, 0.43; 95% CI, 0.33-0.53; P < .001). Concordance between patient and research staff race and ethnicity was associated with increased odds of affirmative consent (OR, 2.72; 95% CI, 1.99-3.73; P < .001). Conclusions and Relevance: In this cohort study, patients from underrepresented racial and ethnic groups and those with lower socioeconomic status were less likely to participate in ophthalmic clinical studies. Concordance of race and ethnicity between patients and research staff was associated with improved participant enrollment. These findings underscore the importance of increasing diversity in clinical research teams to improve racial and ethnic representation in clinical studies.

Thyroid Eye Disease.

Thyroid eye disease (TED), an autoimmune inflammatory disorder of the orbit, presents with a potential array of clinical sequelae. The pathophysiology behind TED has been partially characterized in the literature. There remain certain elusive mechanisms welcoming of research advances. Disease presentation can vary, but those that follow a characteristic course start mild and increase in severity before plateauing into an inactive phase. Diagnosis and evaluation include careful physical examination, targeted laboratory work up, appropriate imaging studies, and tailored treatment regimens. Special consideration may apply to certain populations, such as pediatric and pregnant patients.

Partial Stenosis and Complete Punctal Closure Following Topical Netarsudil Use for Glaucoma.

PURPOSE: To describe patients who developed partial or complete punctal closure after the use of topical netarsudil in the treatment of glaucoma, with documented reversal of symptoms on drug cessation. PATIENTS AND METHODS: This is a retrospective, single-center case series including patients treated with topical netarsudil who were documented to have developed punctal disease ipsilateral to the eye(s) being treated. A literature review was also performed to identify other similar reports. RESULTS: A total of 10 patients were included in the study. Six patients developed partial punctal stenosis and 4 patients developed complete closure of the puncta in 1 or both eye(s) ipsilateral to the use of the topical medication. None of the patients developed punctal disease on the non-netarsudil side. The time from initiation of netarsudil to the documentation of punctal disease ranged from 5-32.2 months (18.41±9.94). In the patients with complete punctal closure, discontinuation of the topical medication led to clinical reappearance of the punctal opening, ranging from 31-83 days after drug cessation (45.75±21.57). In 8 cases, discontinuation of netarsudil resulted in improved epiphora and degree of punctal stenosis on clinical examination. CONCLUSIONS: The use of topical netarsudil for glaucoma may lead to punctal stenosis and complete punctal closure. These side effects of netarsudil are relevant to therapeutic considerations for glaucoma patients.

Unilateral Familial Exudative Vitreoretinopathy: Clinical Profile and Pathology.

We report a case of a newborn with unilateral retinal detachment that could not be repaired. At examination under anesthesia, the retina was markedly abnormal and a presumptive diagnosis of retinal dysplasia was made. Several years later, the eye was enucleated because it was blind and painful. Final pathology was consistent with familial exudative vitreoretinopathy (FEVR). The literature describing unilateral retinal dysplasia is sparse. This case adds to the clinical spectrum of pathologic findings in FEVR.

Non-Arteritic Anterior Ischemic Optic Neuropathy in Pilots.

BACKGROUND: Non-arteritic anterior ischemic optic neuropathy (NAION) is a common cause of optic neuropathy with the exact pathophysiology unknown. Risk factors include advanced age, small optic nerve head, hypertension, diabetes mellitus, and sleep apnea.6 High altitude is considered another risk factor, although only few cases have been reported. No cases of NAION have been reported to occur during flight.CASE REPORT: A 41-yr-old male pilot presented with vision change while performing high G-force maneuvers in an A10 fighter jet. He developed a paracentral visual field defect superiorly in the left eye. Contrasted MRI was within normal limits. The left optic nerve showed blurred margins while the right was sharp, but cupless. The left eye had similar episodes 16 mo before and 8 mo after, but not during flight.DISCUSSION: Our case may be the first reported NAION during flight in an airplane pilot. Our patient was an active U.S. Air Force pilot whose second episode of NAION occurred while performing maneuvers in a fighter jet. The patient is younger than expected for NAION and he did not have any of the commonly associated risk factors. His nonflight episodes suggest he was predisposed to NAION. G-force maneuvers, which restrict blood flow and force blood to the extremities away from the optic nerve head, were the precipitant of his second NAION. With a single case, whether high G maneuvers in general are a risk factor for NAION is unknown.Distefano AG, Lam BL. Non-arteritic anterior ischemic optic neuropathy in pilots.
