Sulfur mustard (SM) is a strong blistering, highly reactive, lipophilic chemical war agent that causes injury in different organs including the skin, eyes and respiratory tract. The Eyes are especially susceptible to the consequences of SM poisoning because of the aqueous and mucosal nature of conjunctiva and cornea. DNA alkylation and depletion of glutathione, are the most important mechanisms of SM action in the eye injuries. Acute clinical symptoms are including decrease in visual acuity, dryness, photophobia, blepharospasm, conjunctivitis and complaints of foreign body sensation and soreness that gradually progress to severe ocular pain...

PURPOSE: To provide guidelines for safe implantation of glaucoma drainage devices (GDDs) in small and pediatric eyes to avoid contact between the optic nerve (ON) and the posterior edge of the GDD plate. METHODS: We developed a formula for calculating limbus-to-ON distance to estimate the available "real estate" for GDD placement in small eyes. The formula was validated using eyes of pediatric decedents undergoing clinical autopsy, with axial lengths (AL) of 15-24 mm...

BACKGROUND: Laxity of the eyelid and periorbital area, a common manifestation of aging, is usually addressed via blepharoplasty and/ or fat transfer. Given the trend toward safer, less invasive treatments preferred by those patients reticent to undergo more invasive procedures, viable alternatives have been sought. Transcutaneous temperature controlled radiofrequency (TTCRF) integrates non- invasive super cial RF treatment with automatic temperature feedback control of energy deposition, as a stimulator of overall collagen remodeling; however, the globe of the eye is particularly sensitive to RF energy...

REVIEW
Abhirup Mandal, Rohit Bisht, Ilva D Rupenthal, Ashim K Mitra
Effective intraocular drug delivery poses a major challenge due to the presence of various elimination mechanisms and physiological barriers that result in low ocular bioavailability after topical application. Over the past decades, polymeric micelles have emerged as one of the most promising drug delivery platforms for the management of ocular diseases affecting the anterior (dry eye syndrome) and posterior (age-related macular degeneration, diabetic retinopathy and glaucoma) segments of the eye. Promising preclinical efficacy results from both in-vitro and in-vivo animal studies have led to their steady progression through clinical trials...

BACKGROUND: Few treatment modalities are available for treating alopecia areata (AA) of the eyebrow. Due to the anatomical proximity of the eyebrows to the eyes, safety issues and side effects should always be taken into consideration when choosing the treatment modality. This study was designed to examine the efficacy of superficial cryotherapy on patients with AA of the eyebrow. METHODS: Superficial cryotherapy was performed every other week on the right eyebrow (SC-treated) in a total of 20 patients who had been previously treated with diphenylcyclopropenone (DPCP) immunotherapy on the scalp...

Children with autism spectrum disorder (ASD) show reduced gaze to social partners. Eye contact during live interactions is often measured using stationary cameras that capture various views of the child, but determining a child's precise gaze target within another's face is nearly impossible. This study compared eye gaze coding derived from stationary cameras to coding derived from a "point-of-view" (PoV) camera on the social partner. Interobserver agreement for gaze targets was higher using PoV cameras relative to stationary cameras...
