Electroretinography in newborn and young infants without sedation
International audience; Purpose: Electroretinography (ERG) is frequently a relevant diagnostic test in pediatric ophthalmology and neurology. ERG at early age is not easy to perform and requires simplified recording protocols and specific norms. In our laboratory especially devoted to developmental studies, an ERG recording method has been adapted to the very young infant. Methods: Monocular ERG was performed in 60 healthy subjects from birth at term to 3 years of age. ERG was recorded using disposable contact lens electrodes in the conscious child with eyes open, after topical anesthesia but without sedation. Stimulus was a white flash (color temperature 5600°K, energy at source 0.3J) appl…

Anatomical and functional macular changes after rhegmatogenous retinal detachment with macula off
International audience; Purpose: To evaluate the correlation between morphologic changes in the outer retina and visual function after successful repair of rhegmatogenous retinal detachment with macula off. Methods: Thirty patients (30 eyes) with successful repair of rhegmatogenous retinal detachment (RD) after macula off and a minimum 6-month follow-up after the surgery were examined. Preoperative characteristics of the RD (visual acuity and duration) were collected. Postoperative visual acuity measurement with ETDRS scale and fundus autofluorescence (FAF) were performed. Spectral-Domain Optical Coherence Tomography (HRA OCT) of outer retina was performed to analyse the number of disrupted…

Macular sensitivity and structure in idiopathic epiretinal membranes 12 months after surgical treatment
Purpose: To evaluate macular sensitivity (MS) change and its correlation with visual acuity (VA) and Spectral-Domain Optical Coherence Tomography (SD-OCT) in patients with idiopathic epiretinal membrane (ERM) at 3, 6 and 12 months after surgical treatment.Methods: Prospective, monocenter, interventional case series. We included 49 patients (49 eyes) with an idiopathic ERM scheduled for a surgical treatment. Among these patients, 40 were evaluated at 3 and 6 months (M3, M6), and 31 at 12 months (M12) after ERM and internal limiting membrane removal. At each visit a measurement of best-corrected visual acuity (ETDRS), a microperimetry and a SD-OCT were performed for all patients.Results: The …
Neurophysiologic Testing in Infants With Usher Syndrome Type 1
Purpose: Usher syndrome type 1 needs to be diagnosed at early age, when speech therapy and cochlear implantation can stimulate communication in a deaf child who will confront an additional visual handicap. Molecular diagnosis is not routinely available. Visual function tests are not easily performed in young children. Before the age of six years, progressive retinal degeneration does not always show fundoscopic changes and few data are available regarding neurophysiologic abnormalities. This study was designed to describe electroretinogram (ERG) and visual evoked potentials (VEP) in a series of fourteen children with Usher syndrome type I.Methods: Monocular ERG and binocular VEP were perfor…
Choroidal thickness in glaucoma patients and glaucoma suspects measured by spectral domain coherence optical tomography
Purpose: The aim of our study was to evaluate and compare retro-foveolar choroidal thickness (RFCT) of healthy subjects, individuals with intraocular hypertension, patients with primary open-angle glaucoma (POAG), patients with normal tension glaucoma (NTG) and patients with primary angle-closure glaucoma (PACG) by spectral domain optical coherence tomography (SD-OCT).Methods: Sixty-five healthy eyes, 30 eyes with intraocular hypertension, 90 eyes with POAG, 30 eyes with NTG and 20 eyes with PACG were included in this cross-sectional study. RFCT, foveolar retinal thickness and average retinal nerve fiber layer thickness (RNFL) were measured by SD-OCT (Spectralis HRA-OCT, Heidelberg Engineer…
