Melanoma of the eye is rare, but can mimic a range of disorders. This report highlights 2 cases of choroidal melanoma with vision loss mimicking neurological diagnoses. The first patient is a 41-year-old white male with a known history of multiple sclerosis and a previous episode of optic neuritis in the right eye, who presented with a 6-month history of decreased vision in the same eye, and oc...

Idiopathic central serous chorioretinopathy (ICSC) is an uncommon disease with the potential to cause loss of visual acuity, decreased color vision, and decreased depth perception. These visual changes may become permanent and require removal of aviators from flight status. This study reviews 55 eyes of 47 USAF aviators with ICSC examined at the United States Air Force School of Aerospace Medic...

Food deprivation alters the processing of sensory information, increasing neural activity in the olfactory and gustatory systems in animals across phyla. Neural signaling is metabolically costly, and a hungry animal has limited energy reserves, so we hypothesized that neural activity in other systems may be downregulated by food deprivation. We investigated this hypothesis in the motion vision ...

PURPOSE To evaluate how sutureless amniotic membrane patches may affect visual functions in normal human eyes. DESIGN Prospective intervention study. METHODS Ten sets of sutureless amniotic membrane patch manufactured as PROKERA were inserted in one eye of six normal patients. Four sets (one each) were inserted in four patients, while six sets (three each) were inserted in two patients. Unc...

Soldiers are subjected to increased risk of musculoskeletal injuries in night operations because of limited visual input. The purpose of this study was to determine the effect of vision removal on lower extremity kinematics and vertical ground reaction forces during two-legged drop landings. The researchers tested 139 Air Assault Soldiers performing a landing task with and without vision. Remov...

PURPOSE To test the efficacy of a novel dual treatment for improving accommodative accuracy and dynamics in young persons with myopia. METHODS Ninety-three young persons with myopia (mean spherical equivalent, -3.0 +/- 1.8 D; age 16.8 +/- 2.1 years; spherical aberration +0.06 +/- 0.04 microm) participated in the study. Custom-designed soft contact lenses were used to alter ocular SA to -0.10 ...

Purpose: To describe a rare occurrence of acute vision loss and diffuse alveolar hemorrhage following a treatment of injectable gluteal cosmetic filler. Patient and methods: A 20-year-old female underwent a cosmetic injection of unknown components for gluteal augmentation. Within hours she developed progressive shortness of breath secondary to diffuse alveolar hemorrhage. She presented to ophth...

Ocular toxoplasmosis is a common vision-threatening disease in Indonesia. Diagnosis of this disease is based on characteristic ophthalmoscopic appearances and laboratory findings. Between 1985 and 1989, the authors retrospectively evaluated 41 children under 12 years of age. Thirteen cases had retinal lesions suspected to be toxoplasmosis but the laboratory findings were negative. The remaining...

PURPOSE To evaluate the diode laser photodynamic therapy efficacy on choroidal neovascularization (CNV) in the treatment of three patients with age-related macular degeneration (ARMD). METHODS The authors selected three patients with ARMD whose vision has decreased due to CNV, and applied diode laser treatment after injecting an indocyanine green (ICG) solution. The patients were followed for...

A 54 year old healthy man presented with a two-month history of decreased vision of the right eye (OD). His past medical history was unremarkable, with no history of smoking. Vision was 1/60 for OD and 1.0 for the left eye (OS). The right eye showed a large, solid choroidal mass with exudative retinal detachment and was clinically suspected for a choroidal metastasis. CT imaging revealed pulmon...
