    OBJECTIVE: To determine the sensitivity and specificity of vision screening using the Medical Technology and Innovations (MTI), Inc., PhotoScreener.

    DESIGN: Cross-sectional study. PARTICIPANTS AND TESTING: Three hundred ninety-two children less than 4 years of age received a complete ophthalmologic examination and were photographed using the MTI PhotoScreener. One hundred three children had normal examinations, and the remaining 284 children had conditions of interest for pediatric ...

    OBJECTIVE: To compare the rate of refractive growth in pseudophakic children's eyes to that of aphakic eyes.

    DESIGN: Multicenter, retrospective observational case series.

    PARTICIPANTS: 83 patients with pseudophakic eyes (100 eyes) and 74 patients with aphakic eyes (106 eyes), with an age of surgery between 3 months and 10 years and a minimum follow-up time of 3 years or more, depending on the age at surgery.

    METHODS: A logarithmic model was used to analyze the rate of refractive growth ...

    BACKGROUND: The treatment of Brown syndrome has been undergoing an evolution toward more effective procedures with fewer operative interventions. Dr Kenneth Wright has introduced a procedure of superior oblique muscle tenotomy with a silicone expander to reduce the incidence of overcorrection.

    METHODS: There was a retrospective study of 20 eyes of 19 consecutive patients with moderate or severe Brown syndrome (Brown syndrome "plus"). Follow-up ranged from 12 to 72 months. The expander, ...

    BACKGROUND: Children who have had cataract removal tend to have decreasing hyperopia (myopic shift) as they grow older. We wondered if the rate of myopic shift could be determined by age at surgery, cataract type, glaucoma, or other factors.

    METHODS: We studied 156 aphakic eyes of children who had cataract surgery before age 10 and documented refractions for more than 3 years. Refraction was corrected with contact lenses and spectacles; glaucoma was managed with medicine and surgery. ...

    In a retrospective study, a computer-based stepwise discriminant analysis was used to create a biostatistical model of the results of surgery in congenital esotropia. One hundred fifty-seven patients who had bilateral medial rectus muscle recession as an initial operative procedure with at least 6 months postoperative follow-up were studied. The outcome groups for the discriminant analysis were based on the ocular deviation 6 weeks after the first surgery and at the patient's last visit, ...

    PURPOSE: Previous studies of outcome in children with aphakia have approached the data by grouping patients according to features such as age at surgery, type of procedure, or some other common attribute. The purpose of this study is to identify factors predictive for visual outcome and complications in pediatric patients with cataracts.

    METHOD: One hundred seventy-four eyes in 118 patients underwent lensectomy and anterior vitrectomy for congenital or juvenile cataracts. All received ...

    PURPOSE: Open-angle glaucoma may develop after surgery for congenital or developmental cataract with an incidence ranging from 3% to 41%. The pathogenesis of "aphakic" (open-angle) glaucoma remains unknown. Despite numerous reported clinical series (>1000 eyes), we are unaware of any reported case of open-angle glaucoma after primary intraocular lens (IOL) implantation for congenital or developmental cataract. We decided to test the hypothesis that primary posterior chamber IOL ...

    OBJECTIVE: Children with aphakia tend to have decreasing hyperopia as they grow older. No large study of the long-term refractive changes in children with pseudophakia has been published, although myopic shifts of greater than 10 diopters (D) have been reported. The authors used the refractions of children with aphakia and long follow-up to calculate the theoretic long-term refractive effects of pseudophakia.

    DESIGN: The study design was a chart review of eyes that underwent cataract ...

    OBJECTIVE: To examine the ability of the Medical Technology and Innovations (MTI), Inc., Photoscreener (Cedar Falls, IA) to detect hyperopia and to improve the photograph grading criteria to screen for amblyopiogenic levels of hyperopia.

    DESIGN: Cross-sectional study and reanalysis. PARTICIPANTS AND TESTING: In previous work, 392 participants received a complete ophthalmologic examination and were photographed using the MTI Photoscreener. For this study, all 209 participants with normal ...

    The eyes of 392 consecutive childhood cataract aspiration procedures were analysed for frequency of the development of chronic glaucoma and retinal detachment and the performance of secondary membrane surgery. Three different modifications of the aspiration procedure were employed: the standard needle and syringe procedure leaving the posterior capsule intact (304 eyes), rotoextraction with small opening of the posterior capsule (34 eyes) and Ocutome aspiration with wide excision of the ...

    OBJECTIVE: This study aimed to determine the ability of healthcare professionals and lay volunteers to grade photoscreening photographs.

    DESIGN: The study design was a cross-sectional study.

    PARTICIPANTS AND INTERVENTION: One hundred children 3 years of age or younger received a complete ophthalmologic examination and were photographed using the Medical Technology Innovations (MTI) photoscreener. Twenty-six children had normal examination results, and the remaining 74 children had ...

    PURPOSE: To determine whether time of strabismus surgery for patients with acquired intermittent exotropia and constant exotropia influences postoperative sensory outcome.

    METHODS: In a retrospective, cross-sectional study, 76 patients with acquired intermittent or constant exotropia and motor realignment were evaluated for postoperative sensory status. Age at surgery, duration of exotropia, and presence of intermittent or constant exotropia were correlated with postoperative sensory ...

    PURPOSE: Although binocular vision deficits occur in children who have a constant esotropia onset following significant maturation of stereopsis, it is uncertain whether adults are susceptible to changes to binocular vision. We examined binocular vision in adults with longstanding surgical monovision (> or =6 month's duration) to determine whether the binocular visual system remains susceptible to change.

    METHODS: Participants included 32 adults with longstanding monovision through ...

    A statistical analysis of the onset and natural history of primary inferior oblique eye muscle overaction (IOOA) was conducted using the records of 456 strabismus patients. With 5 years or more of follow-up, IOOA developed in 72% of congenital esotropes (CETs), 34% of accommodative esotropes (AETs), and 32% of intermittent exotropes (X[T]s) at an average age of 3.6, 5.2, and 5.2 years, respectively. Incidence of IOOA was positively related to the number of horizontal surgeries in CETs ...

    Introduction For several years we have recognized an unusual eye reaction in some children after eye muscle surgery. The reaction appears unexpectedly, most often about one week after the operation. It is characterized by discomfort and itchiness of the eye, chemosis and hyperemia of the conjunctiva, and edema of the eyelids. The symptoms usually subside in 12 to 48 hours. At times the eye signs appear within 24 hours after operation. In these cases the reaction frequently is more ...
