Electrophysiological testing of visual function after mirror telescope implantation: a case report

Abstract

The mirror telescope preserved peripheral vision in contrast to classic telescopes; however, the telescope concurrently reduced the luminance of the magnified retinal image, which was likely responsible for the prolongation of the VEP latencies.

Scharioth Macula Lens: A new intraocular implant for low-vision patients with stabilized maculopathy- first experience

“…Many older visually impaired adults have difficulty in getting used to a new device and refuse to use them. Some disadvantages of external aids can be surpassed using intraocular implants 3,4 .…”

Vision before and after scharioth macular lens implantation in patients with AMD: an electrophysiological study

“…Regarding the use of electrophysiological examination of patients with AMD and an optical implant, we found only one published report (pubmed.gov searched for “visual evoked potential macular degeneration implant” in June 2020) describing the longitudinal monitoring of a 70-year-old female and a 90-year-old male with LMI implants [ 9 ]. While distant visual acuity increased after LMI implantation, and peripheral projection was preserved, the M-VEP M20° peak time was prolonged after implantation.…”

“…Our stimulation parameters and conditions were already described elsewhere [ 9 ], and they were intentionally kept similar to those used in our previous study of the intraocular mirror telescope—OriLens (LMI-Lipshitz Macular Implant). The only difference between the two studies was the pattern check size.…”

“…While these telescopes still limit the visual field of view by 20-24°, they can substantially improve quality of life [4][5][6][7]. This limitation led to progression from a Galilean type toward a mirror lens telescope (Cassegrain type) and opened peripheral vision [8]; however, it reduced contrast and luminance [9]. The disadvantage of the implanted aids is that they cannot be adjusted for a desired focus/magnification.…”

Methods of Improving the Visual Functions in Patients with Stable Maculopathy – Pilot Results of a New Study

“…Zraková rehabilitace je založena na opakovaném tréninku zrakových dovedností, jako je lokalizace, fixace, skenování a sledování objektu a zlepšení čtecí rychlosti [5,10]. Čtení se SML má totiž svá specifika.…”
