IPoster: Dilation or No Dilation for Threshold Visual Field Testing: Optometric Practice Patterns
Differences in philosophy for visual field (VF) testing have been noted. The purpose was to assess whether optometrists dilate their patients prior to threshold VF.
IPoster: Predicting End-of-Day Clearance and Effect of Solution Viscosity in Scleral Lens Wear Over Time
This study aims to evaluate the settling of a scleral lens and if this process is influenced by the nature of the fluid layer.
IPoster: Scleral Lenses in Current Ophthalmic Practice Evaluation: Patient Demographics, Indications and Lens Designs
This multi-center study reports demographics of scleral lens wearers and scleral lens prescription patterns as reported in an online survey.
IPoster: SD-OCT May Help Differentiate Adult-Onset Fovealmacular Vitelliform Dystrophy from Age-Related Macular Degeneration
Adult-onset fovealmacular vitelliform dystrophy (AOFVD) is a retinal dystrophy, characterized by bilateral foveal, yellow, round elevated subretinal lesions. These lesions mimic drusen and are often misdiagnosed as age-related macular degeneration (AMD). SD-OCT may be a useful technique to assist in distinguishing these two conditions.
IPoster: Vision-Related Quality of Life in Keratoconus: Scleral versus Corneal Gas Permeable Lens Correction
Identify differences in vision-related quality of life (VRQoL) for keratoconic (KCN) persons with scleral gas permeable (SGP) correction as compared to corneal gas permeable (CGP) correction. Contact lens comfort and handling were also assessed.
IPoster: Variability in Retinal Vessel Density Using Manufacturer Software and Publicly Available Image Processing Software in Optical Coherence Tomography Angiography
Many optical coherence tomography angiography (OCTA) devices are available, but not all of them provide quantitative measurements of retinal vasculature. Practitioners usually use publicly available image processing software to analyze OCTA images. This study compared vessel density results obtained using ImageJ with those obtained using a software recently launched by a manufacturer.
IPoster: Ocular Surface Imaging to Assess Tear Film Dynamics Associated with Contact Lens Wear
To evaluate the use of ocular surface imaging on pre-corneal tear film (PCTF) and pre-lens tear film (PLTF) dynamics associated with contact lens wear. To quantify changes in the PLTF on contact lens surfaces differing in material composition. To assess possible visual effects of PLTF changes during the course of a 6 hour period using high and low contrast visual acuity.
IPoster: Ocular Microbial Flora in Contact Lens and Non-Contact Lens Wearers – Are They Symptomatic?
To evaluate the microbial profile in Contact Lens (CL) wearers and non- Contact Lens wearers and to compare with symptomatic and asymptomatic contact lens wearers.
IPoster: Management of Corneo-Scleral Irregularities with Virtually Designed Custom Multi-Meridian Scleral Lenses
Toric haptic scleral lens designs are prescribed more often than in previous years. Recent interest in mapping the sclera and conjunctiva is proving that scleral shape is highly variable, and may explain the difficulty in fitting some patients with scleral lenses. A corneo-scleral topographical system was utilized to evaluate ocular shape of two patients. Custom multi-meridian back surface toric haptic scleral lenses were empirically designed to address the unusual scleral shape, which significantly deviated from a sin2 bitoric curve with a periodicity of 180°.
