A 67-year-old female with visual impairment secondary to macular degeneration complains of seeing frightening images for 3 days. She states that she sees a translucent elongated face with disproportionately large teeth and ears (Figure 1). There are no associated mental status changes, auditory hallucinations, headaches, fever or seizures. Clinical examination is normal aside from decreased vis...

mal position. On examination, the patient had blepharitis and corneal haze in both eyes (Figure 3). Ophthalmic examination showed no light perception in the right eye and a visual acuity of 20/200 in the left eye. Slitlamp examination showed palpebral conjunctival hyperemia with papillary hypertrophy and tears in the Descemet membrane in both eyes (Figure 4). Funduscopic examination showed bila...

In their everyday life, people interact with different objects, static as well as those in motion. However, dynamic acuity is rarely checked in medical examinations, even those preceding the issue of driving license. In order for driving to be safe, good eyesight or good correction with visual aids is imperative. Beside good eyesight, drivers also have to have good reflexes and short reaction s...

In 74 normal subjects (62 children aged 5-8 years and 12 adults), we tested the widely-held belief that visual sensitivity improves substantially during childhood. Maturation of the retino-striate pathways is generally invoked to account for age-related changes in visual sensitivity. We evaluated the extent to which attentional factors unduly emphasized the effect of age on the purely physiolog...

Visual field test and optic disc evaluation are the standard examination techniques used to detect the onset and progression of glaucoma. This explorative study was performed to assess the temporal correlation between visual field and optic disc changes in eyes with ocular hypertension and well-established glaucoma. Eighty-six hypertensive and 16 glaucomatous eyes were followed up for a period ...

BACKGROUND hip fractures are an increasing source of morbidity and mortality in older people. The role of visual function tests such as visual impairment, stereopsis, contrast sensitivity and visual field defects in low fragility hip fractures in Asian populations is not well understood. OBJECTIVE to determine the association between various visual function tests and low fragility hip fractur...

OBJECTIVE To characterize habitual visual acuity, contrast sensitivity, spectacle use, and eye care utilization in a large sample of older adults residing in nursing homes. METHODS Of 33 nursing homes identified in Birmingham, Alabama, 17 served as sites. Eligibility criteria included age 55 years or older, English-speaking, and Mini-Mental State Examination score of 13 or higher. Habitual di...

The paper presents the use of visual evoked potentials VEP to objective assessment acuity. Methods using (VEP) rely on changes electrical action generated within cortex. To diagnose degree weakening eyesight a series studies healthy people and visually impaired ones were made. Electrophysiological eye, noninvasive examination allow gives objectivity in acuity what may be very important ophthalm...

OBJECTIVE To investigate the clinical features and visual outcome of patients with peripapillary staphyloma. METHODS The medical records of patients diagnosed as having peripapillary staphyloma at Seoul National University Children's Hospital, Seoul, Korea, between January 1, 1991, and December 31, 2003, were reviewed. Visual acuity and associated ocular and systemic abnormalities were record...
