Functional visual loss

Ophthalmology Clinics of North America, 2004
Functional visual loss is a common problem encountered in practice. It must be recognized that this problem occurs in patients who have organic illness. Manual perimetry is the most effective method for evaluating functional visual loss, and the presence of a central scotoma in a functional visual field strongly suggests that organic pathology is ...

Functional hearing loss

The Laryngoscope, 1976
AbstractFunctional hearing loss is a rather common entity, although it probably is overlooked more often than not. In most instances, the services of an experienced audiologist are necessary if one is to detect these cases.First, one must consider carefully the patient's behavior before and during the otologic and audiologic examination, and note the ...

Functional visual loss

Current Opinion in Neurology, 2017
Purpose of review Functional visual loss (FVL) is a syndrome in which subjective visual parameters are inconsistent with objective measures. Recent advances in understanding the pathophysiology and management of functional disorders and FVL will be explored.

Robust Loss Functions for Boosting

Neural Computation, 2007
Boosting is known as a gradient descent algorithm over loss functions. It is often pointed out that the typical boosting algorithm, Adaboost, is highly affected by outliers. In this letter, loss functions for robust boosting are studied. Based on the concept of robust statistics, we propose a transformation of loss functions that makes boosting ...

Functional Visual Loss

American Journal of Ophthalmology, 1985
Patients with functional loss of visual acuity or visual fields range from the "deliberate malingerer" to the "suggestible innocent." Between these extremes are patients with varying mixtures of fraud and suggestibility. These patients do not, as a rule, have psychiatric disease and do not need to see a psychiatrist. The ophthalmologist must be able to

Functional vision loss

Current Opinion in Ophthalmology, 2012
Functional disorders are a major category of vision loss not uncommonly presenting to an ophthalmologist or neuro-ophthalmologist. There are constant advances in the discrimination of causes for functional vision loss, as well as testing and treatment of these patients.New tests for diagnosing functional vision loss have been reported.

The Loss of Visual Function in Glaucoma

Seminars in Ophthalmology, 2000
This article reviews innovative techniques for assessing the visual field and for examining glaucoma patients for evidence of visual field progression. The authors discuss the algorithms for assessing change in visual fields used in each of several multicenter studies sponsored by the National Eye Institute.
