NCT ID: NCT02201979 Completed - Ptosis Clinical Trials

Laser Fluorescent Imaging of Nipple and Areola During Breast Lift

Start date: July 2014
Phase: N/A
Study type: Observational

Breast lift surgery performed in combination with breast implants is a common cosmetic operation. However, there have been concerns regarding the safety of this treatment combination. Some investigators are concerned that an implant may increase the risk of complications, including loss of circulation to the nipple and areola. This study was undertaken to evaluate the blood supply of the breast using intraoperative laser fluorescent imaging and to determine whether a breast implant compromises blood supply to the nipple and areola.

Vision Screening for the Detection of Amblyopia

Start date: September 12, 2011
Phase: N/A
Study type: Interventional

INTRODUCTION. Amblyopia is defined as the loss of visual acuity (VA) in one or both eyes, without any obvious structural or pathological anomalies. Amblyopic eye should be able to regain some VA if treatment is initiated before the age of seven. It is the leading cause of monocular blindness in the 20- to 70-year olds with prevalence 2-5%. Amblyopia is mainly monocular, hence children are general asymptomatic. VA testing is the only reliable method of detecting amblyopia, and the fourth year of life is considered best for vision screening programs. AIM: The purpose of the study is to reduce the preventable vision loss. The main goal of the study is to evidence the problem of amblyopia in Zagreb and to release a model for formal, government directed vision-screening program as a Croatian public health policy. HYPOTHESIS. In Croatia, the prevalence and actual effect of amblyopia and amblyogenic factors, along with treatment efficacy is impossible to quantify, since no population-based studies have been performed regarding this issue. In addition, national screening of preschool children does not exist, while the school-entry screening is prescribed by law. The object of the study is to determine the prevalence of amblyopia in a 4-4.5 year old children of The Town of Zagreb, the efficacy of screening and effectiveness of treatment on reducing amblyopia prevalence. The primary hypothesis is defined: screening of visual acuity monocularly at distance and near in 4-4.5 year old children in Zagreb is effective in detecting amblyopia. PATIENTS AND METHODS: Monocular vision of about 7000 children/ year aged 4-4.5 for whom both parents gave consent is to be tested with Lea chart at near (40cm) and distance (3m) in the kindergartens of The Town of Zagreb. The criterion for referral to complete ophthalmological examination is VA <0.8.
