LETTERS Case of acute zonal occult outer retinopathy with altitudinal hemianopsia Since the clinical entity of acute zonal occult outer retinopathy (AZOOR) was initially proposed, 1 it has been noted that the visual loss may be misattributed to lesions in the optic nerve or central nervous system. Even with a likely visual field defect for those diseases—an afferent pupillary defect and reduced...

OBJECTIVE To quantify the variability of scotomas detected by 10-2 visual field (VF) testing with a red target in patients taking hydroxychloroquine without and with retinopathy. DESIGN Retrospective review of clinical charts and VFs. METHODS Twenty-four patients taking hydroxychloroquine without retinopathy, and eight patients taking hydroxychloroquine with retinopathy were tested in this ...

PURPOSE To describe the first case of retinal injury by a misuse of a toy using light-emitting diode. METHODS A 15-year-old male Japanese student received irradiation on his right eye by a 5 mW light-emitting diode of 410 nm wavelength for 20 seconds in 2 days. He noticed decreased vision and central scotoma approximately 2 weeks later from these events. The mechanism of injury was evaluated ...

Following circumscribed retinal damage, extensive reorganization of topographically organized visual cortical areas has been demonstrated in several species of mammals (including humans). Although reorganization is often studied over extended time scales, neural response properties change within seconds of retinal deafferentation. Understanding the mechanisms underlying these short-term effects...

PURPOSE The safety of bioptic telescopes for driving remains controversial. The ring scotoma, an area to the telescope eye due to the telescope magnification, has been the main cause of concern. This study evaluates whether bioptic users can use the fellow eye to detect in hazards driving videos that fall in the ring scotoma area. METHODS Twelve visually impaired bioptic users watched a serie...

We report the favorable anatomic and functional outcome of photodynamic therapy with verteporfin in a case of chronic central serous chorioretinopathy complicated with choroidal neovascularization (CNV). This 37-year-old Chinese male with bilateral chronic central serous chorioretinopathy presented with central scotoma, reduced vision and metamorphopsia in his right eye. Fluorescein angiography...

Acute Macular Neuro-retinopathy (AMN) is a rare clinical entity. We present case of 26 years old male who presented with one-week history sudden onset decrease vision in left eye associated paracentral scotomas. Dilated fundus examination the showed multiple reddish brownish petalloid para-foveal lesions apex pointing toward fovea. OCT hyper-reflective bands Outer Nuclear Layer and Plexiform al...
