Visual field impairment affects more than 100 million people globally. However, due to the lack of the access to appropriate ophthalmic healthcare in undeveloped regions as a result of associated costs and expertise this number may be an underestimate. Improved access to affordable diagnostic software designed for visual field examination could slow the progression of diseases, such as glaucoma...

Fused hidden Markov models (FHMMs) have been shown to work well for the task of audio-visual speaker recognition, but only in an output decision-fusion configuration of both the audioand video-biased versions of the FHMM structure. This paper looks at the performance of the audioand video-biased versions independently, and shows that the audio-biased version is considerably more capable for spe...

Visual loss is a common symptom in neurologic emergencies. Although ocular causes of visual loss are usually identifi ed by eye care specialists, many patients appear in an emergency department or a neurologist’s offi ce when the ocular examination is normal or when it suggests a neurologic disorder. Indeed, many causes of monocular or binocular acute visual loss may reveal or precede a neurolo...

This case report describes the detection of homonymous hemianopsia and delirium during the admission physical examination of a patient with esophageal adenocarcinoma, resulting in the new diagnosis of subacute hemorrhagic stroke. The poststroke visual field defect can result in significant disability and reduction in quality of life. Patients with visual field cut show a severely reduced qualit...

A new instrument for visual field examination with binocular fixation is described. The binocular vision was dissociated with polarizing plates. Only the point of fixation was visible to both eyes while the testing chart (Amsler chart) was visible to one eye in the use of this apparatus. The examination was done with both the patient's eyes open. With the use of this apparatus, not only was the...

The authors report a case of binasal hemianopia in a 34-year-old female who, at the age of 22 years, underwent resection of a pinealoma located at the 3rd ventricle. Less than a year after the surgery, partial visual field losses occurred. Examination of retina, retinal nerve fiber layer (RNFL) as well as examination of the ganglion cell complex (GCC) excluded a pregeniculate lesion. Functional...

Method: Thirty-three clusters of 50 subjects ≥ 50 years old were randomly selected. Consenting subjects underwent enumeration to establish a demographic profile and thereafter a clinical examination. Visual acuity (VA) was measured with a Tumbling ‘E’ chart; participants having a VA < 6/18 were retested with a pinhole. If no improvement in VA occurred, subjects underwent clinical examination, i...

purpose: to report a uveal metastasis from infiltrative ductal carcinoma of breast. case report: a 45 year old woman with 9 year history of left breast ductal carcinoma and axillary lymph nodes involvement has found soft tissue are right eye uveal metastasis after 5 and 9 years respectively. conclusion: every patient with breast carcinoma should have complete eye examination at least every 6 mo...

purpose: to report a case of anterior segment eye deposits in a patient on long-term chlorpromazine therapy. case report: a 34 years old man had been on chlorpromazine therapy for 5 years with a total dose of 1,100 gram. since one year ago, he presented with gradual onset of decreased visual acuity in both eyes. slit-lamp examination revealed multiple fine yellow-brown deposits on the corneal e...

RATIONALE Occlusive cerebrovascular disease is the most common cause of homonymous hemianopia (HH) with macular sparing. PATIENT CONCERNS A 61-year-old man came to our ophthalmology clinic complaining of right-side hemianopia. Ophthalmic examination, visual field (VF) examination, and brain magnetic resonance imaging (MRI) were performed. DIAGNOSES He had right HH without macular sparing on...
