Case series: Traumatic ocular lacerations secondary to pressure washers

Purpose

Numerous causes of ocular lacerations, including, open globe injuries have been extensively reported but to our knowledge this is first time that pressure washers have been reported to be the culprit. Thus, in this case series we describe the uniqueness of ocular findings secondary to high-power pressure washer injuries that are a result of their mechanistic function.

Observations

Here we report a case series of 3 patients who presented in an emergency department with pain and decreased visual acuity following usage of high-pressure washer machines. All three patients presented with features of both blunt and sharp mechanisms of ocular injury. Most lacerations caused injury that encompassed more than one zone. Two of the patients experienced an open globe injury, and all patients had poor final visual outcomes. Extraocular involvement included fractures and lid lacerations. All patients were managed surgically with repair of the ocular defects. Visual outcome in the first patient was hand motion, while the second patient received a prosthesis following enucleation due to lack of recovery after four months. Lastly, we were unable able to obtain visual outcome for the third patient due to lack of follow up.

Conclusion

Ocular injuries due to pressure washers have not been reported in literature, however, this case series serves to elucidate that pressure washers can cause ocular injuries with both blunt and laceration mechanical effects. Moreover, special care should be taken in preventing and managing these injuries due to their high ocular morbidity.

Ocular adverse effects of therapeutic biologics

Biological drugs, termed biologics, are medications that contain or are derived from a living organism (human, animal, or microorganism). With new biological agents being approved by the Food and Drug Administration (FDA) every year, clinicians need to know potential ocular adverse effects that are associated with these drugs. This review provides an overview of ocular adverse effects of biological medications used to treat both ophthalmic and non-ophthalmic diseases. We searched PubMed for relevant case reports, case series, reviews, and clinical trials reporting ocular adverse effects caused by biologics. This review was conducted in June 2021 and investigated the drugs listed in the most updated (April 2021) FDA Purple Book Database of Licensed Biological Products. This review focuses on monoclonal antibodies, interleukins, and receptor fusion proteins. We explore ocular side effects of 33 biological drugs, stating whether they are frequent, common, or rare.

A One Year Longitudinal Comparative Analysis of Visual Outcomes Between Femtosecond Laser-Assisted Cataract Surgery and Standard Phacoemulsification Cataract Surgery

Purpose

To assess visual outcomes over time of femtosecond laser-assisted cataract surgery compared to standard phacoemulsification cataract surgery.

Design

A retrospective, single-center comparative study.

Methods

Patient data including demographics, ocular biometry, pre- and postoperative visual acuity, postoperative complications, primary (uncorrected distance visual acuity over time) and secondary visual outcomes (uncorrected near visual acuity, best distance visual acuity, patient complaints, satisfaction, and postoperative surgery) were gathered and statistically analyzed. Demographic differences between patients receiving femtosecond-laser assisted cataract surgery (FLACS) versus standard phacoemulsification cataract surgery (PCS) were corrected for outcome comparison. Safety, efficacy, predictability, and stability were analyzed for each procedure and compared.

Results

A total of 155 eyes in PCS and 143 eyes in FLACS were analyzed at 1 week, 3 months, and 1 year using odds ratio. The odds ratio of being 20/20 or better and 20/40 or better at the specified time periods were similar and statistically insignificant at all time periods analyzed except 20/20 or better for uncorrected distance visual acuity (UDVA) at 1 year (p=0.0001) and uncorrected near visual acuity (UNVA) at 1 week (p=0.02). In both cases, the odds of being 20/20 or better favored FLACS. Mean UDVA, UNVA, and best distance visual acuity (BDVA) were all similar and statistically insignificant between the two groups. Postoperative patient complaints, safety, efficacy, predictability, and stability between the two groups showed no statistical significance.

Conclusion

Despite the odds ratio of being 20/20 or better favoring FLACS for UDVA at 1 year and UNVA at 1 week, the mean logMAR UDVA, BDVA, and UNVA were similar and statistically insignificant between the FLACS and PCS groups at 1 week, 3 months, and 1 year. Differences in visual acuity were likely due to differences other than surgical approaches. While both FLACS and PCS are appropriate approaches to cataract surgery, one does not appear to be superior when assessing longitudinal markers for visual acuity, safety, efficacy, predictability and stability.

Agreement of anterior segment measurements between four diagnostic imaging devices in myopic patients

PURPOSE

To compare the inter-device agreement of anterior chamber depth (ACD), central corneal thickness (CCT), flat keratometry (K1), steep keratometry (K2), corneal astigmatism (ΔK), and white-to-white (WTW) measurements.

METHODS

This is a retrospective study with 73 myopic patients (142 eyes). We extracted and compared anterior segment measurements (ACD, CCT, K1, K2, ΔK, and WTW) of four devices (OPD-Scan III, Pentacam HR, Lenstar LS 900, and Galilei G4), and performed pairwise agreement comparisons between them.

RESULTS

Agreement analyses revealed that the most agreement occurred: in Pentacam HR and Galilei G4 for ACD measurements, in Pentacam HR and Lenstar LS 900 for CCT measurements, in OPD-Scan III and Galilei G4 for WTW measurements, in OPD-Scan III and Pentacam HR for K1 and K2 measurements, and OPD-Scan III and Galilei G4 for ΔK measurements.

CONCLUSION

OPD-Scan III is interchangeable with both Galilei G4 and Lenstar LS 900 for WTW measurements. OPD-Scan III and the Pentacam-HR are interchangeable in K1, K2, and ΔK measurements. OPD-Scan III and Lenstar LS 900, and OPD-Scan III and Galilei G4 are interchangeable in K1 and ΔK measurements, respectively.

Sex differences in the association between suicide attempts and glucose disturbances in first-episode and drug naive patients with major depressive disorder

BACKGROUND

Glucose metabolism is related to depression, but the relationship between blood glucose and suicide attempts in patients with major depressive disorder (MDD) remains unclear. This large-scale sample explores the relationship between suicide attempts and fasting blood glucose, in addition to sex differences in first-episode and drug naive (FEDN) MDD patients.

METHODS

1718 FEDN MDD patients diagnosed for the first time were recruited, and their demographic data, clinical data, and blood glucose indicators were collected. 17-item Hamilton Depression Rating Scale (HAMD), 14-item Hamilton Anxiety Rating Scale (HAMA), and positive subscale of the Positive and Negative Syndrome Scale (PANSS) were used to assess their depression, anxiety and psychotic symptoms, respectively.

RESULTS

The depression, anxiety, psychotic symptoms and blood sugar levels of the suicide attempt group were higher than those of the non-suicide attempt group. Correlation analysis showed that blood glucose was significantly associated with suicide attempts in male and female patients. While binary logistic regression showed that blood glucose levels were significantly associated with suicide attempts in male patients, it showed that suicide attempts were not significantly associated with blood glucose levels in female patients.

LIMITATIONS

The main limitations are cross-sectional design and inability to control selection bias.

CONCLUSIONS

In male MDD patients, fasting blood glucose level is a potential biomarker of suicide attempt, which deserves attention to avoid suicide risk. However, in female patients, fasting blood glucose has no significant correlation to suicide attempts.
