Serous Retinopathy Associated With Combination MEK and Fibroblast Growth Factor Receptor Inhibitor.

Purpose: To present a case of a chemotherapy regimen combining a fibroblast growth factor receptor (FGFR) and mitogen-activated protein kinase kinase (MEK) inhibitor leading to serous retinopathy. Methods: A retrospective chart review of a single case was performed. Results: A 67-year-old man with pancreatic and prostate cancer developed bilateral multifocal pockets of subretinal fluid while on an experimental chemotherapy regimen combining an MEK inhibitor (trametinib) and an FGFR inhibitor (erdafitinib). Conclusions: Given that FGFR lies upstream to the mitogen-activated protein kinase signaling pathway, retinal toxicity may be more severe and more common with FGFR-MEK combination therapy. Future studies are necessary to guide ophthalmic surveillance.

Risk of Infectious Endophthalmitis From a Resident-Performed Intravitreal Injection.

PURPOSE: This work assesses the safety of resident-performed intravitreal injections by comparing the incidence of postinjection endophthalmitis associated with residents vs surgical retina attendings. METHODS: In this retrospective noninferiority cohort study, the Current Procedural Technology code for an intravitreal injection was used to identify patients from July 1, 2015, to October 31, 2018, at a single-center Veterans Affairs hospital where patients receive intravitreal injections from attending vitreoretinal surgeons and residents. The medical record for each injection was reviewed for the training level of the proceduralist, indication, medication, and laterality. The main outcome was the incidence of postinjection endophthalmitis occurring within 30 days of an intravitreal injection, which was confirmed by at least 2 medical-record reviewers. RESULTS: In this cohort of 593 patients, most were male (97.0%), and the average age was 70.3 years (±10.8 years). Of the 6934 injections given, 3877 (55.9%) were performed by residents and 3057 (44.1%) by attendings. Of the 5 cases of endophthalmitis identified, 3 were associated with a resident-performed injection in his or her fourth year of postgraduate training. The difference (0.012%; 95% CI, -0.168% to 0.169%) in the incidence of postinjection endophthalmitis between residents (0.077%) and attendings (0.065%) did not cross the predetermined noninferiority limit (0.200%). CONCLUSIONS: At our teaching clinic, resident-performed injections were not associated with an elevated risk of endophthalmitis when compared with attending-performed injections. Under varying levels of supervision, residents appeared to demonstrate appropriate sterile injection technique.

Outcomes and Complications of Concurrent Pars Plana Vitrectomy and Scleral-Fixated Intraocular Lens Placement Using Gore-Tex Suture.

Purpose: The authors aim to describe the visual outcomes and postoperative complications of concurrent pars plana vitrectomy and scleral-fixated intraocular lens (IOL) placement using Gore-Tex suture. Methods: A retrospective review of medical records was performed on 27 eyes of 27 patients undergoing concurrent pars plana vitrectomy and scleral-fixated IOL with Gore-Tex suture. Outcome measures were change in preoperative and postoperative visual acuity, final manifest refraction, and incidence of intraoperative and postoperative complications. Results: The mean age was 69.2 ± 11.3 years; there were 16 male patients (59%). The duration of follow-up ranged from 33 to 576 days with a mean of 200 ± 143 days. All patients received Bausch + Lomb Akreos AO60 IOL. The overall mean best-corrected visual acuity in Snellen equivalent improved from 20/276 preoperatively to 20/44 postoperatively (P < .001). The mean postoperative manifest spherical equivalent refraction was -0.35 ± 1.34 diopters (D). Seventy-five percent of eyes were ± 1.0 D of target refraction. Postoperative complications included corneal edema (26.0%), ocular hypertension (25.9%), hypotony (7.4%), cystoid macular edema (7.4%), vitreous hemorrhage (7.4%), and hyphema (3.7%). No cases of suture breakage, IOL dislocation, retinal detachment, or uveitis-glaucoma-hyphema syndrome were identified. Conclusions: The use of Gore-Tex suture for posterior chamber IOL fixation resulted in favorable outcomes. No suture-related complications occurred during the follow-up period. Final refraction in this setting is typically within ± 1.0 D of target.

Utility of Ophthalmologic Screening for Patients With Candida Bloodstream Infections: A Systematic Review.

Importance: The Infectious Diseases Society of America recommends ophthalmologic examinations for everyone with positive Candida blood culture results (candidemia) to screen for endophthalmitis, a practice that remains controversial because of multiple concerns for its limited usefulness and potential for harm. Objective: To determine guideline efficacy by reconciling discrepancies in the incidence of endophthalmitis and evaluating outcomes of studies assessing ophthalmologic screening for candidemia. Evidence Review: PubMed literature searches, including the search terms candidemia, fungemia, chorioretinitis, and endophthalmitis, identified longitudinal studies prior to 2018 of patients who underwent ophthalmologic evaluations in the setting of positive fungal blood culture results regardless of symptoms or clinical status. Additional studies not captured by these queries were found by manually scanning references within the articles captured by the queries. Ambiguous studies of patients with concomitant bacterial or viral infections were excluded. Findings: Thirty-eight applicable studies of 7472 patients who underwent ophthalmologic screening for candidemia or fungemia were identified. Criteria were compared with the conventional definition of endophthalmitis based on present (concordant) or absent (discordant) frank vitreous involvement. Concordant (59 of 6693 [0.9%]) and discordant (114 of 779 [14.6%]) endophthalmitis incidence rates differed by 13.8% (95% CI, 11.4%-16.4%; P < .001). Visual acuity for each case was recorded verbatim as subjective report provided by each study, when available. None of the concordant endophthalmitis cases reported direct, intraocular, microscopic evidence of Candida or other fungal organisms. Outcomes were available for 19 patients with concordant endophthalmitis; 6 died within 4 weeks of screening. The rate of substantial vision loss was associated (φ = 0.58; 95% CI, 0.01-0.86; P = .046) with additional invasive intervention (3 of 6 [50.0%]) compared with medical management alone (0 of 6). Conclusions and Relevance: In this systematic review without meta-analysis, inconsistent definitions of endophthalmitis accounted for discrepancies of its incidence and overreporting among patients with candidemia, contributing to bias and resulting in the construction of guidelines. As few as 3 of 7472 patients had potential improvement, while routine examination overall could lead to additional interventions and harm in this population. These findings suggest that indiscriminate screening based on candidemia alone does not appear to be supported by the literature and should be reevaluated for inclusion as a recommendation from the Infectious Diseases Society of America.

CLEARED (Chemicals and Litmus testing with Effective Alkaline Range for Eye Damage): A Prospective, Interventional Study.

OBJECTIVES: While immediate diagnosis and irrigation is standard chemical eye burn practice, it is unknown to what extent specific pH measurements influence management, given the frequent clinical availability of narrow-spectrum nitrazine pH strips. We hypothesize that exclusive broad-spectrum pH strip implementation leads to more accurate measurement and expedited ophthalmologic consultation. METHODS: At a Level I trauma center over 25 months, all emergent adult ophthalmology consultations for chemical burns were included in a pre-intervention (n = 22) and post-intervention (n = 20) study design. During this time, narrow-spectrum nitrazine pH strips available to non-obstetric emergency department (ED) staff were exclusively replaced by broad-spectrum strips. Causative chemical, time from triage to ophthalmology consultation, examination findings, ocular pH by ED and ophthalmology staff, and irrigation quantity were analyzed. RESULTS: Most burns were alkaline. Time from triage (p = 0.043) and irrigation quantity following consultation (p = 0.047) each decreased following exclusive ED implementation of broad-spectrum pH strips. There was greater pH congruence between consulting and primary physicians after intervention (p = 0.03). CONCLUSIONS: Exclusive non-obstetric implementation of broad-spectrum pH strips may allow greater accuracy and faster management of ocular chemical burns. Availability of narrow-spectrum pH strips may be dangerous clinically by falsely reassuring the examiner with inherent inaccuracy.

Prospective analysis of pediatric ocular chemical burns: laundry detergent pods.

PURPOSE: To present data on chemical ocular burns in children seen at a single tertiary care facility resulting from accidental eye exposure to the contents of laundry detergent pods. METHODS: All emergent pediatric ophthalmology consultations specific for chemical ocular burns at a level I trauma center were included as part of a prospective quality improvement investigation over a 13-month period. Age, causative agent, and examination findings at presentation and final follow-up were recorded and analyzed. RESULTS: A total of 12 children with chemical ocular burns were seen during the study period. All patients were ≤5 years of age. Most chemical ocular burn consultations (n = 8) were specific to ocular exposure of laundry detergent pod contents; the remainder were associated with conventional cleaning agents or pesticides (n = 4). There was a significant association between laundry detergent pod as causative agent and a patient age of 2-5 years, compared to <2 years and any other agent (P = 0.018 [Fisher exact test]). CONCLUSIONS: In our study, laundry detergent pods were the most frequent cause of chemical ocular burns in children. Additionally, preschoolers may be at a higher risk of sustaining these injuries. Increased public awareness, product safety improvements, and/or regulation may be advisable to decrease the ocular hazards associated with laundry detergent pods.
