Acute retinal necrosis (ARN syndrome) is a rare syndrome; the germs involved belong to the herpes virus family. Complications include cystoid macular edema and retinal detachment, which is a frequent complication with a poor prognosis. We report the case of an immunocompetent patient with unilateral acute retinal necrosis due to VZV. The drop in visual acuity was brutal. Intravenous antiviral and anti-inflammatory therapy was initiated on an emergency basis, followed by oral maintenance therapy. The patient was complicated during this treatment by cystoid macular edema treated with retrobulbar steroids injections. The Knowledge of this condition, which diagnosis is essentially clinical, is necessary in order to avoid the extension of retinal necrosis and to prevent the reccurrence of complications.
Anthrax is an anthropozoonos is caused by Bacillus anthracis, a gram-positive, nonmotile, spore-forming rod that is found in soil and predominantly causes disease in herbivores such as cattle, goats, and sheep. Contamination is due to contact with sick animals or their contaminated products. The three major clinical forms of anthrax are gastrointestinal, cutaneous, and inhalational. It mostly occurs in exposed skin areas, like the face, neck and forearms. In the face, the eyelidis the most common site of infection. We report the case of 6-year-old femal child with a history of contact with animals who presented an eyelid anthrax complicatedcy a septicshoc.
Purpose: this population-based epidemiological study highlights the prevalence and causes of non-glaucomatous optic atrophy (NGOA) in Ehime Mbano.
Methods: In this prospective study, the case history, visual acuity, pupillary reflex and fundoscopy examination for three hundred and forty-nine (349) subjects between ages 17-85 was carried out using a pro forma, snellen chart, pen light and ophthalmoscope respectively. The presumed NGOA subjects (45) were further examined with perimetry and tonometry to rule out glaucomatous OA. The data collected was analyzed with the use of ANOVA and Chi-square statistical tests.
Results: The highest prevalence rate (20%) was accounted for by retinitis pigmentosa, nutritional amblyopia and unknown causes. Females (53.3%) more than males, had NGOA. Age ranges 57£77 had (20%) highest prevalence of NGOA. Most of the presumed NGOA cases (34.6%) had visual acuity of < 6/6-6/18 (20/20 – 20/63).
Conclusion: The total prevalence of NGOA in Ehime Mbano is 13.0%. The prevalence of NGOA is related to causes and visual acuity but not dependent on sex and age. More studies with larger sample sizes are however warranted to strengthen the correlation. Patients with presumed OA should be thoroughly evaluated as it may be a treatable condition or presentation of some other life-threatening conditions.
The present sttudy highlights the Visual acuity in patients before and after the first month phacoemulsification surgery. Phacoemulsification is the most common surgical treatment of ocular cataract. Removing the lens from a small incision, avoidance of intraoperative and postoperative complications and quick visual rehabilitation (visual acuity) are its advantages. This clinical study investigated the changes in V.A. of 80 patients 15 and 30 days after surgery. In all of the cases, postoperative astigmatism with a higher value of 1.75 D was measured, 30 days after surgery, there was a slight improvement in postoperative astigmatism. Clinical research, concluded that the restoration of vision of all patients was at high level from 0.26 to 0.89 and without any major complications within the first month after Phacoemulsification.
This review aims to make clear that applying contact lenses is not a risk factor for infection by coronavirus when the users follow the rules of personal hygiene. In December 2019, a coronavirus (CoV) epidemic broke out in China, causing severe acute respiratory syndrome. Today it has become a pandemic of coronavirus 2019 (COVID-19). In today's patient care environment, physicians and their primary care staff are responsible for ensuring that all guidelines and requirements for the care of all patients are strictly adhered to.
