CASE REPORT A case of maculopathy due to "poppers" is described. DISCUSSION Poppers is a drug composed of various forms of alkyl nitrite. A 39 year-old man, who had been using poppers for years, was seen in the clinic with phosphenes, reduced visual acuity and central scotoma. The SD-OCT in the right eye showed disruption at the level of the IS/OS junction line. The SD-OCT scan in the left ey...

Simultaneous branch retinal artery and vein occlusion is a rare condition that may cause severe visual loss, and its treatment is often unrewarding. Herein, we report a case with simultaneous central retinal vein and branch retinal artery occlusion; it was successfully treated with a single dexamethasone intravitreal implant. The affected eye attained a visual acuity level of 20/25 from the vis...

Occult macular dystrophy is an inherited macular dystrophy characterized by a progressive decline of bilateral visual acuity with normal fundus appearance, fluorescein angiogram and full-field electroretinogram. This case report presents a 20-year-old female patient with bilateral progressive decline of visual acuity for six years. Her visual acuity was 3-4/10 in both eyes. Anterior segment and...

Dengue infection is epidemic but ocular complications of dengue are less reported. We report a case of dengueinfected patient with disturbing ocular symptoms. He was admitted for severe dengue. Subsequently, he presented with symptoms of bilateral central scotoma with metamorphosia. Fundus examination revealed cotton wool spots and flame-shaped haemorrhages at the macula, with dull foveal light...

We characterized the perceptual, functional, and structural abnormalities associated with retinal ischemia during a cotton wool spot episode and its sequelae. The border of the visually salient field anomaly mirrored the quantitatively measured relative scotoma. Results of resolution perimetry and high resolution imaging indicated that there was a substantial loss of retinal ganglion cells with...

purpose: to determine the prevalence of various types of visual field defects in patients with open angle glaucoma at the time of diagnosis. methods: this cross-sectional study was performed on patients who were referred to our glaucoma clinic. open angle glaucoma was confirmed by intraocular pressure measurement, perimetry, fundoscopic examination and gonioscopy. the last perimetry of patients...

Spatial contrast sensitivity was measured in normal subjects with and without a retinally stabilized artificial scotoma (either circular or rectangular), which precluded foveal vision. Our results indicate that the type of contrast sensitivity loss obtained (predominantly high frequency or overall) depended on temporal factors associated with grating presentation. A predominantly high frequency...
