Lacrimal gland botulinum toxin injection for epiphora management.

Purpose: Epiphora remains an often difficult to manage ocular complaint for ophthalmologists in all subspecialties. This review seeks to examine the safety and efficacy of botulinum toxin injection for management of chronic epiphora.

Methods: The authors conducted a Pubmed search for studies on the use of lacrimal and transplanted salivary gland botulinum toxin injections for the management of epiphora within the past 20 years.

The effect of visually significant dermatochalasis and blepharoptosis on driving safety.

Objective: To evaluate the impact of visually significant blepharoptosis and dermatochalasis on driving safety and performance. Patients with visually significant blepharoptosis often complain of difficulty with driving, but the impact of blepharoptosis on driving has not been evaluated in a real-world setting.

Methods: Retrospective cohort study of 610 consecutive adult patients undergoing bilateral functional blepharoplasty or ptosis repair surgery at a single, University-based practice between 2014 and 2017.

Can indocyanine green perfusion imaging detect microangiopathy in mastectomy skin flaps?

Intraoperative vascular imaging using indocyanine green (ICG) angiography may better predict flap viability than clinical judgement alone. Intraoperative ICG angiography was used in a chronic corticosteroid user undergoing bilateral nipple sparing mastectomy with expander placement. Large blood vessels were visualized, however, the skin surrounding these vessels remained dark.

Acquired Pediatric Brown Syndrome Secondary to Sinusitis.

Acquired pediatric Brown syndrome is rarely associated with sinusitis. Children may present with diplopia, elevation deficiency in adduction, and a head tilt or chin-up position. Magnetic resonance imaging can confirm the diagnosis.

Improved cookstoves and their effect on carbon monoxide levels in San Lucas Tolimán, Guatemala.

Introduction: Installation of ventilated cookstoves has been shown to improve 24-h carbon monoxide (CO) and particulate exposure in the Guatemalan highlands. However, a survey of villagers around San Lucas Tolimán found much higher than expected CO levels. Our purpose is to evaluate the effects of improved cookstoves on CO levels in these villagers.
