Visual Psychophysics / Physiological Optics - ARVO

ARVO 2013 Annual Meeting Abstracts by Scientific Section/Group – Visual Psychophysics / Physiological OpticsConclusions: Zonular Capture Haptic based accommodativedisaccommodativeIOL’s demonstrate a useful range ofaccommodation and significant axial shift in a first prototype, proofof concept IOL model.Conclusions: A significant difference in the number of patients withhigh scattered light measurements were observed in the patients withfloaters and no PVD. The exact nature of this difference needs to befurther evaluated. It is possible that only floaters close to the retinalsurface are able to induce a measureable light scattering and beresponsible for the clinical manifestations.Axial ShiftCommercial Relationships: Paul M.

MIOS, Lausanne, Switzerland.Purpose: To evaluate if straylight measures taken in patients withcomplaints of floaters (and no posterior vitreous detachment [PVD])are different from patients presenting with a PVD.Methods: A retrospective review of patients having undergone astraylight measurement with a C-Quant (Oculus, Germany) whopresented with a complaint of floaters or observed to have a PVDwhen examined but who did not complain of floaters. Data wascollected on age, status of the lens, and only the initial C-Quantmeasurement was analyzed if several were taken. Only patients withintact vitreous were considered in the study. Straylight measurementswere considered significant if they were above 2 standard deviations[SD] from a normative database, controlled for age.Results: The mean age for both groups was 58.58 years with an SDof 12.75 years. Thrity one eyes from 29 patients were included, 11eyes with a diagnosis of PVD, and 20 eyes with floaters. In the PVDgroup, only 5 eyes had measures above the 2 SD cutoff, while 14 of20 eyes in the floaters group met this criterion. The mean straylightvalue for the floaters group was 1.88 with an SD of 1.42 and for thePVD group of 1.24 with an SD of 0.25. The differences between bothgroups did not reach statistical significance (p=0.087).Commercial Relationships: Miguel Castilla, None; Marc D. deSmet, Thrombogenics (P), Thrombogenics (C), Sanofi (C), Bayer(C), Regeneron (C), Preceyes (R), Allergan (C), Janssens (R), GSK(C), CRL (C)Program Number: 569 Poster Board Number: C0180Presentation Time: 10:30 AM - 12:15 PMVisual findings in children with Autistic Spectrum DisorderPamela M.

The aim of this study wasto investigate visual findings in a large population of children withASD.Methods: Children with ASD (n=88, mean age 10.7 years ±3.1years, range 5-16 years) were recruited from a regional populationbasedregister (n=67) and special education schools (n=21). ASDdiagnosis was available from the register and classified as; Autism(AU) n=50, Asperger’s syndrome (AS) n=33, unspecified n=5. Agematchedcontrols were recruited from mainstream schools (n=204,mean age 11.5 years ±3.1 years).Monocular recognition crowded VA, presence of strabismus, NPC,fusional reserves (FR) and Frisby stereoacuity scores were assessed.Results: Table 1 presents success rates and summary statistics for alldata.Controls demonstrated slightly but significantly better VA than theASD group (Mann Whitney z=-2.49, p
