Cataract after silicone oil implantation
Springer Science and Business Media LLC - Tập 83 - Trang 79-82 - 1993
Dabov Borislav
During the period January 1987 till December 1990 192 patients (204 eyes) underwent pars plana vitrectomy (PPV) with silicone oil internal tamponade. 141 eyes were phakic and 63 eyes aphakic. 65 of the phacic eyes were diabetic, and 76 eyes nondiabetic. The silicone oil was removed on average at 8.3 months postoperatively. Cataract developed faster in the nondiabetic group and in the eyes with par...... hiện toàn bộ
Comparing the RETeval® portable ERG device with more traditional tabletop ERG systems in normal subjects and selected retinopathies
Springer Science and Business Media LLC - Tập 146 - Trang 137-150 - 2022
Jia Yue You, Allison L. Dorfman, Mathieu Gauvin, Dylan Vatcher, Robert C. Polomeno, John M. Little, Pierre Lachapelle
Our study aimed to determine if ISCEV standard-like ERGs recorded with the LKC RETeval® portable ERG unit compared to those obtained using the more traditional tabletop unit. ERGs recorded from normal subjects and patients affected with retinal ON and OFF pathway anomalies were compared. Analysis included peak time and amplitude measurements as well as time–frequency domain analysis with the discr...... hiện toàn bộ

Contrast sensitivity differences between strabismic and anisometropic amblyopia: objective correlate by means of visual evoked responses
Springer Science and Business Media LLC - Tập 58 - Trang 45-50 - 1984
Emilio C. Campos, Maria Luisa Prampolini, Rozanna Gulli
The visual evoked response transfer function of amblyopic subjects was studied. Strabismic amblyopes showed abnormalities only in the high spatial frequency range. Anisometropic amblyopes on the contrary, showed an abnormal function both in the low and high spatial frequency range. This is an objective correlate of functional differences between strabismic and anisometropic amblyopes.
Versuche zur isolierung und analyse der exophthalmus-produzierenden substanz des hypophysenvorderlappens
Springer Science and Business Media LLC - Tập 26 - Trang 375-383 - 1969
M. U. Dardenne, N. Poonawalla, H. Haase
In der vorliegenden Arbeit konnte gezeigt werden, daß das thyreotrope Hormon Ambinon® in 10 verschiedene Proteinfraktionen auftrennbar ist. Nur in 3 dieser Fraktionen, die nur einen sehr geringen Anteil der gesamten Eiweißmenge ausmachen, war eine exophthalmogene Aktivität nachweisbar. Die Aminosäurenanalysen der aktiven Fraktionen zeigten charakteristische Unterschiede zu der eiweißhaltigen Frakt...... hiện toàn bộ
Faster and more sensitive VEP recording in children
Springer Science and Business Media LLC - Tập 107 - Trang 251-259 - 2003
Alison M. Mackay, Ruth Hamilton, Michael S. Bradnam
Purpose: In the difficult-to-test paediatric population, shorter test procedures are desirable. This study investigates whether Laplacian analysis of a three occipital-electrode montage detects steady-state VEPs (ssVEPs) more often or faster in children than a conventional montage, and if so, in which age groups. Methods: Steady-state VEPs (7.78 reversals/s; checkerboard stimulus) to various chec...... hiện toàn bộ
Chiasmal syndrome ophthalmological and neuro-radiological aspects
Springer Science and Business Media LLC - - 1982
J. T. W. van Dalen, B. J. W. M. Verbeeten, F. L. M. Peeters
The chiasmal syndrome has distinct ophthalmological features such as visual field loss, optic disc changes, decrease in visual acuity, ocular motor disturbances and exophthalmos. However, the pathological processes in the chiasmal region often give rise to differential diagnostic problems. Before the era of computer tomography (CT) these processes could only be visualized by means of indirect or i...... hiện toàn bộ
Instrument myopia conceptions, misconceptions, and influencing factors
Springer Science and Business Media LLC - Tập 62 - Trang 281-308 - 1986
M. F. Wesner, R. J. Miller
The literature on instrument myopia is reviewed, with the review organized around three principal objectives. One is to describe and discuss various factors that may influence the degree to which instrument myopia is manifested, including monocular vs. binocular viewing, age, direction of focus, illumination level, fatigue, magnification, astigmatic variations, optical decentration, perceived prox...... hiện toàn bộ
Restoration of vision by combined experimental antithymocyte therapy, and orbital radiation with high-dose steroids for severe, acute, steroid-refractory, congestive thyroid orbitopathy
Springer Science and Business Media LLC - - Trang 1-9 - 2023
Monika Sarnat-Kucharczyk, Dorota Pojda-Wilczek, Maria Świerkot, Grażyna Kulawik, Ewa Mrukwa-Kominek
We report diagnostic and therapeutic dilemmas in the difficult case of compressive optic neuropathy with severe visual acuity and visual field loss with subsequent visual recovery in both eyes, in a patient with Graves’ orbitopathy (GO) by a combination of experimental antithymocyte therapy, orbital radiotherapy with high-dose steroids. A 72-year-old man presented with severe vision loss in both e...... hiện toàn bộ
