IMPORTANCEA review of the injury patterns, treatment strategies, and responding physicians' experience during the Port of Beirut blast may help guide future ophthalmic disaster response plans.OBJECTIVE To present the ophthalmic injuries and difficulties encountered as a result of the Port of Beirut blast on August 4, 2020. DESIGN, SETTING, AND PARTICIPANTSA retrospective medical record review of all patients who presented to the emergency department and 13 ophthalmology outpatient clinics at the American University of Beirut Medical Center for treatment of ophthalmic injuries sustained from the explosion in Port of Beirut, Beirut, Lebanon, from August 4 to the end of November 2020. Patients were identified from emergency records, outpatient records, and operative reports.MAIN OUTCOMES AND MEASURES Types of ocular injuries, final best-corrected visual acuity, and need for surgical intervention were evaluated. Visual acuity was measured with correction based on noncycloplegic refraction using the Snellen medical record. EXPOSURES Ocular or ocular adnexal injuries sustained from the Port of Beirut explosion.RESULTS A total of 39 blast survivors with ocular injuries were included in this study. Twenty-two patients presented with ocular injuries on the day of the blast, and 17 patients presented within the following 3 months to the ophthalmology clinics for a total of 48 eyes of 39 patients were treated secondary to the blast. Thirty-five patients (89.6%) were adults, and 24 (61.5%) were female. A total of 21 patients (53.8%) required surgical intervention, more than half of which were urgently requested on the same day of presentation (14 [35.9%]). Most eye injuries were caused by debris and shrapnel from shattered glass leading to surface injury (26 [54.2%]), eyelid lacerations (20 [41.6%]), orbital fractures (14 [29.2%]), brow lacerations (10 [20.8%]), hyphema (9 [18.8%]), open globe injuries (10 [20.8%]), and other global injuries. Only 7 injured eyes (14.5%) had a final best-corrected visual acuity of less than 20/200, including all 4 open globe injuries with primary no light perception (8.3%) requiring enucleation or evisceration. CONCLUSIONS AND RELEVANCEIn the aftermath of the Port of Beirut explosion, a review of the ophthalmic injuries showed a predominance of shrapnel-based injuries, many of which had a delayed presentation owing to the strain placed on health care services. Reverting to basic approaches was necessary in the context of a malfunctioning electronic medical record system.
Purpose: To describe an original technique to unfold the graft in vitrectomized eyes undergoing Descemet membrane endothelial keratoplasty (DMEK). Methods: We performed a retrospective chart and video review of successive cases presenting with corneal decompensation in vitrectomized eyes or aphakic eyes in which DMEK or combined DMEK/scleral-fixated intraocular lens implantation was indicated and in which a specific technique [Cornea-Press (C-Press)] was used to unfold the graft. C-Press is characterized by corneal indentation intended to artificially shallow the anterior chamber and allow the graft to unroll. Best spectacle-corrected visual acuity, central corneal thickness, the time of graft unfolding, endothelial cell count, and the incidence of intraoperative/postoperative complications were analyzed. Results: Eleven eyes of 11 patients (8 men, mean age: 73 ± 12 years) were included. Corrected distance visual acuity (logarithm of the minimum angle of resolution) improved from 1.44 ± 0.23 preoperatively to 0.77 ± 0.36 6 months postoperatively (P < 0.001). Central corneal thickness (CCT) decreased from 644 ± 79 preoperatively to 516 ± 49 μm 6 months postoperatively. The graft unfolding time was 4.4 ± 2.5 minutes. Mean endothelial cell density was 2762 ± 192 preoperatively and 1872 ± 324 cells/mm2 6 months postoperatively. No eye showed intraoperative complications. Rebubbling for partial detachment was needed in 2 cases (18%). Conclusions: The C-Press technique enables likely safe and reproducible DMEK surgery in vitrectomized eyes. Further clinical studies with a large number of patients and longer follow-up are required to confirm our preliminary results.
Background: Patient education demonstrates variable benefits on diabetes control. Introduction: To examine the effect of discussing nonmydriatic retinal imaging findings during a single endocrinology visit on HbA1c levels after 6, 12, and 60 months. Materials and Methods: Patients with HbA1c >8.0% and diabetic retinopathy were previously recruited for a prospective study looking at the change in HbA1c at 3 months between those assigned to a session of nonmydriatic imaging with discussion of retinal findings and those assigned to routine endocrinology evaluation alone. The patients were subsequently evaluated at 6, 12, and 60 months after the initial intervention. Results: Fifty-three of the 57 originally recruited intervention subjects (93%) and 48 of 54 subjects in the original control group (89%) were evaluated at 6 and 12 months and 44 patients in each group (75% and 81%, respectively) at 60 months. At 6 months, the intervention group maintained larger decreases in median HbA1c compared to control (-1.1 vs.-0.3, respectively, p = 0.002) with a trend persisting at 12 months (-0.6 vs.-0.2, respectively, p = 0.07). After 60 months, there was no significant difference in the median change in HbA1c between treatment and control groups (0.3 vs. 0.1, respectively, p = 0.54). Discussion: The short-term improvement in HbA1c resulting from discussion of retinal findings persists throughout the first year in this diabetic cohort, but its magnitude declines with time and becomes statistically insignificant at some point between 6 and 12 months. Conclusions: In patients with poorly controlled diabetes, retinal imaging review may help improve glycemic control but may require repetition periodically for benefit beyond 6 months.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
