Ocular Injuries and Cultural Influences in Afghanistan During 5 Months of Operation Enduring Freedom.

In support of Operation Enduring Freedom, American, North American Treaty Organization (NATO) Coalition, and Afghan forces worked together in training exercises and counterinsurgency operations. While serving at the NATO Role 3 Multinational Medical Unit, Kandahar, Afghanistan, numerous patients with explosive blast injuries (Coalition and Afghan security forces, and insurgents) were treated. A disparity was noted between the ocular injury patterns of US and Coalition forces in comparison with their Afghan counterparts, which were overwhelmingly influenced by the use, or lack thereof, of eye protection.

Intraocular lens calculation adjustment after laser refractive surgery using Scheimpflug imaging.

Purpose: To test a new method of intraocular lens (IOL) calculation after corneal refractive surgery using Scheimpflug imaging (Pentacam HR) and partial coherence interferometry (PCI) (IOLMaster) that does not require historical data; that is, the Schuster/Schanzlin-Thomas-Purcell (SToP) IOL calculator.

Setting: Shiley Eye Center, San Diego, California, and Walter Reed National Military Medical Center, Bethesda, Maryland, USA.

Design: Retrospective data analysis and validation study.

Patterns and severity of vincristine-induced peripheral neuropathy in children with acute lymphoblastic leukemia.

Vincristine, a critical component of combination chemotherapy treatment for pediatric acute lymphoblastic leukemia (ALL), can lead to vincristine-induced peripheral neuropathy (VIPN). Longitudinal VIPN assessments were obtained over 12 months from newly diagnosed children with ALL (N = 128) aged 1-18 years who received vincristine at one of four academic children's hospitals. VIPN assessments were obtained using the Total Neuropathy Score-Pediatric Vincristine (TNS©-PV), National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE©), Balis© grading scale, and Pediatric Neuropathic Pain Scale©-Five (PNPS©-5).

Delayed diagnosis of microsporidial stromal keratitis: unusual Wessely ring presentation and partial treatment with medications against Acanthamoeba.

The authors report a case of an immunocompetent 38-year-old male who presented with an indolent keratitis that eluded diagnosis after multiple cultures taken over 9 months. He was started initially on medications against Acanthamoeba, after presenting with a nearly complete corneal ring 2 months after trauma. These medications likely partially treated his condition, thereby making laboratory diagnosis more difficult.

Visual acuity recovery after late traumatic femtosecond laser in situ keratomileusis flap loss.

We report a case of traumatic flap loss from a fingernail 2 months after femtosecond laser-assisted laser in situ keratomileusis. On presentation, the patient's uncorrected visual acuity (UCVA) was 20/400 and complete flap avulsion was noted. Irrigation and treatment with mitomycin-C were done immediately, and a bandage contact lens was inserted.

Astigmatism: risk factor for postoperative corneal haze in conventional myopic photorefractive keratectomy.

Purpose: To retrospectively assess risk factors other than high myopia for corneal haze in patients who had conventional photorefractive keratectomy (PRK) without mitomycin-C (MMC).

Setting: Department of Ophthalmology, Naval Hospital Camp Pendleton, California, USA.

Methods: This retrospective study comprised 362 eyes of 193 military members who had conventional PRK with the Star excimer laser system from 2004 to 2006.

Medical considerations before refractive surgery retreatment.

We report a case of a significant hyperopic shift 2 years after myopic photorefractive keratectomy with an interim of stability. The patient was an otherwise healthy man who reported a sudden change in vision when climbing to altitude. Medical considerations for refractive shifts should be looked at before retreatment is proposed.
