Distortions and reflections in the high-power Fresnel prisms used in peripheral prism placement can be considerable, and the simplifying assumption that prism deflection power is independent of angle of incidence into the prisms results in substantial errors. We analyze the effects of high prism power and incidence angle on the field expansion, size of the apical scotomas, and image compression\/expansion. We analyze and illustrate the effects of reflections within the Fresnel prisms, primarily due to reflections at the bases, and secondarily due to surface reflections. The strength and location of these effects differs materially depending on whether the serrated prismatic surface is placed toward or away from the eye, and this affects the contribution of the reflections to visual confusion, diplopia, false alarms, and loss of contrast. We conclude with suggestions for controlling and mitigating these effects in clinical practice.<\/jats:p>","DOI":"10.1117\/1.oe.53.6.061707","type":"journal-article","created":{"date-parts":[[2014,1,17]],"date-time":"2014-01-17T12:41:05Z","timestamp":1389962465000},"page":"1-14","source":"Crossref","is-referenced-by-count":20,"title":["Impact of high power and angle of incidence on prism corrections for visual field loss"],"prefix":"10.1117","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5709-6045","authenticated-orcid":false,"given":"Jae-Hyun","family":"Jung","sequence":"first","affiliation":[{"name":"Harvard Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1340-9257","authenticated-orcid":false,"given":"Eliezer","family":"Peli","sequence":"additional","affiliation":[{"name":"Harvard Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"189","reference":[{"key":"r1","doi-asserted-by":"publisher","DOI":"10.1167\/tvst.2.4.2"},{"key":"r2","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000203338.54323.22"},{"key":"r3","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.40.10.1597"},{"key":"r4","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.09-3799"},{"key":"r5","first-page":"1","article-title":"Hazard detection by drivers with paracentral homonymous field loss: a small case series","author":"Bronstad","year":"2011"},{"key":"r6","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/176806"},{"key":"r7","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.2004.047498"},{"key":"r8","first-page":"33","article-title":"Vision-related quality of life in first stroke patients with homonymous visual field defects","author":"Gall","year":"2010"},{"key":"r9","first-page":"363","article-title":"Review of low vision management of visual field defects","author":"Goodlaw","year":"1983"},{"key":"r10","article-title":"Method of using a prism in lens for the treatment of visual field loss","author":"Gottlieb","year":"1988"},{"key":"r11","first-page":"60","article-title":"An overview of enhancement techniques for peripheral field loss","author":"Cohen","year":"1993"},{"key":"r12","doi-asserted-by":"publisher","DOI":"10.1097\/00006324-200009000-00006"},{"key":"r13","doi-asserted-by":"publisher","DOI":"10.1097\/00006324-200209000-00008"},{"key":"r14","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.126.5.657"},{"key":"r15","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.1952.01700030126001"},{"key":"r16","doi-asserted-by":"publisher","DOI":"10.1097\/00006324-197104000-00001"},{"key":"r17","first-page":"1","article-title":"Ray optics","author":"Saleh","year":"1991"},{"key":"r18","first-page":"192","article-title":"Prism","author":"Keating","year":"2002"},{"key":"r19","first-page":"192","article-title":"Polarization and crystal optics","author":"Saleh","year":"1991"},{"key":"r20","doi-asserted-by":"publisher","DOI":"10.1097\/00006324-196306000-00003"},{"key":"r21","first-page":"43","article-title":"Refraction by planes, plates and prisms","author":"Katz","year":"2004"},{"key":"r22","doi-asserted-by":"publisher","DOI":"10.1037\/h0027882"},{"key":"r23","first-page":"468","article-title":"Most naturally occurring human saccades have magnitudes of 15 degrees or less","author":"Bahill","year":"1975"},{"key":"r24","doi-asserted-by":"publisher","DOI":"10.1167\/8.14.25"},{"key":"r25","doi-asserted-by":"publisher","DOI":"10.3758\/BF03194544"},{"key":"r26","doi-asserted-by":"publisher","DOI":"10.3758\/BF03194545"},{"key":"r27","doi-asserted-by":"publisher","DOI":"10.1016\/0028-3932(94)00119-A"},{"key":"r28","article-title":"Driving with hemianopia: 3.
