BACKGROUND: Cataracts occur earlier among HIV-infected adults and this is attributed to various intraocular inflammatory processes that result in early degeneration. In this study we purposed to investigate whether HIV infected individuals with cataracts develop heightened intraocular inflammatory processes compared to their HIV negative counterparts by determining the concentration of 8 cytokines in the aqueous humour of HIV-positive adults with cataracts and their HIV-negative counterparts...

AIM:  Diagnosing homonymous hemianopia (HH) in children can be difficult due to inability to comply with perimetry. Therefore, HH can often only be suspected by magnetic resonance imaging (MRI) showing lesions to the retrochiasmatic visual pathways. The aim of our retrospective observational cross-sectional study was to improve the radiologic detection of HH. METHODS:  MRIs of 21 subjects (5-17 years old) with ophthalmologically confirmed HH (14 complete, 7 incomplete hemianopias) were analyzed...

The purpose is to use laws of physics to elucidate the mechanisms behind capillary non-perfusion in diabetic retinopathy. In diabetic retinopathy, loss of pericytes weakens capillary walls and the vessel dilates. A dilated capillary has reduced resistance to flow, therefore increased flow in that vessel and decreased in adjoining capillaries. A preferential shunt vessel is thus formed from the dilated capillary and the adjacent capillaries become non-perfused. We apply the laws of Laplace and Hagen-Poiseuille to better understand the phenomena that lead to capillary non-perfusion...

Pigmented epithelioid melanocytoma (PEM) of the skin has been rarely reported in ophthalmology. The purpose of this case report is to present a young male born with a progressive, hyperpigmented lesion involving the orbit and intracranial cavity diagnosed as PEM. The case is unique given the young age and the size, multifocality, and growth of this tumor. Identification of this lesion is paramount due to its low-grade malignant potential.

A 35-year-old man was admitted due to somnolence and progressive sensory-motor polyneuropathy, followed by severe visual impairment in both eyes after direct skin exposure to an acrylamide monomer solution. The results of an ophthalmological examination including central critical flicker fusion frequency and the decreased amplitude of action potentials observed in the visual evoked potential studies suggested that acrylamide intoxication resulted in neuronal degeneration in the optic pathways. Additional attention should be directed to the potential effect of acrylamide on the human visual system...
