A controlled trial of povidone-iodine to treat infectious conjunctivitis in children.

Purpose: To report the efficacy of povidone-iodine as a treatment for conjunctivitis in pediatric patients.

Design: Double-masked, controlled, prospective clinical trial.

Methods: In an ophthalmology clinic in a general hospital in Manila, Philippines, 459 children (mean [SD] age 6.

Ocular applications of povidone-iodine.

Ocular infections can have devastating consequences and may lead to blindness. Povidone-iodine (PVP-I) has many potential advantages over the currently used drugs, including a broader antibacterial spectrum, it turns the surface of the eye brown for a few minutes, bacterial resistance has not been seen and it is cheaper than other agents. PVP-I has made a significant contribution to pre- and postoperative ocular surgical prophylaxis, ophthalmia neonatorum prophylaxis and treatment of bacterial conjunctivitis.

Continuous oxygen monitoring of the conjunctiva in neonates.

Objective: To report the first use of a noninvasive conjunctival oxygen monitor in neonates. We wished to investigate if measuring the partial pressure of oxygen directly from the conjunctiva could track hyperoxia and hypoxia as well as, or better than, pulse oximetry. This has the potential to reflect brain oxygenation while yielding important systemic information.

Incentivized digital outcomes collection.

The objective of this study was to assess the feasibility of digital patient satisfaction outcomes collection using the Internet and interactive voice response technology. Patients, health care providers, and industry sponsors were provided with incentives to participate. The participants included the practitioners and patients in medical and surgical practices who used Project Quality Card (patent pending) and the Practice Improvement Program.

Atropine and bifocals can slow the progression of myopia in children.

Background: Atropine 1% ophthalmic solution has been used to retard progression of simple childhood myopia. Problems have been identified in previous studies, including possible observer bias. To address this issue, we evaluated our experience including the duration that atropine maintains a child at 20/30 or better in one spectacle correction compared with controls.

Timing of postoperative adjustment in adjustable suture strabismus surgery.

Purpose: The use of adjustable sutures in strabismus surgery has increased the rate of surgical success. Little data are available on the optimum timing for postoperative adjustment after strabismus surgery. We wanted to compare 2 common practices of adjustable suture technique after strabismus surgery.

Use of the HARK autorefractor in children.

Purpose: We investigated the reliability, accuracy, and repeatability of an autorefractor with the capability of over-refracting and measuring visual acuity for use in children in a prospective study.

Methods: Before and after cycloplegia, 68 children (mean +/- SD age, 10 +/- 3 years, range 5-16 years) underwent autorefraction twice with the HARK 599 Autorefractor (Humphrey Instruments Inc., San Leandro, CA), subjective over-refraction through the HARK autorefractor, and subjective refraction using a phoro-optometer.

The range of ocular movements decreases with aging.

Purpose: To determine whether normal maximum versions change as a function of age.

Methods: One hundred twenty-four healthy subjects without any history of strabismus, ocular or periocular surgery, or major illness were examined to confirm visual acuity better than 20/60 in each eye and the absence of strabismus. Maximum sustained elevation, depression, dextroversion, and levoversion were quantified by using a standardized lateral version light-reflex (LVR) test.

Vertical strabismus in monofixation syndrome.

Purpose: The manifest angle of the horizontal deviation in monofixation syndrome (MFS) has been reported to reach a maximum of 8 to 10 PD. Review of the literature, however, revealed no studies about the vertical deviation associated with MFS. The purpose of this study is to evaluate the range of the angle of the vertical deviation in MFS.

Ocular involvement in patients with posttransplant lymphoproliferative disorder.

Objectives: To describe ocular disease in 3 patients with posttransplant lymphoproliferative disorder (PTLD) and to identify the frequency of such ocular involvement.

Methods: Medical record reviews. Using Kaplan-Meier analysis, we calculated the frequency of ocular involvement among pediatric patients with systemic PTLD after liver transplantation.

Community-based outcomes research: the Project Solo experience.

One of the critical issues in outcomes research is physician participation. The lack of such participation is one of several factors that have made widespread adoption of outcomes measurement slow to materialize. This article focuses on the 6-year experience of Project Solo, a multi-site community-based outcomes research effort.

Posterior fixation sutures: a revised mechanical explanation for the fadenoperation based on rectus extraocular muscle pulleys.

Purpose: To determine the effect of the rectus extraocular muscle pulleys on the fadenoperation, an operation designed to fixate the posterior muscle belly to the underlying retroequatorial sclera.

Methods: First, duction into the field of action of the operated-on muscle was quantified retrospectively after fadenoperation. Magnetic resonance imaging was then performed prospectively after surgery to verify anatomic changes.

The effect of anterior transposition of the inferior oblique muscle on ocular torsion.

Introduction: The effects of anterior transposition of the inferior oblique on elevation in adduction have been studied, but changes in objective ocular torsion have not been investigated.

Methods: A prospective study on the effect of anterior transposition of the inferior oblique on objective torsion with use of fundus photography was undertaken in 24 eyes of 13 patients. The amount of oculartorsion was determined by measuring the angle formed by a horizontal line drawn across the geometric center of the disc and a second line connecting the geometric center to the foveola.
