Abstract

Laser induced maculopathy includes retinal photoreceptor disruption, macular hole, macular hemorrhage, and rarely choroidal neovascularization (CNV). Here we report a case of laser induced CNV that was treated by intravitreal anti-vascular endothelial growth factor (VEGF) injection and resulted in visual improvement and CNV resolution during 1-year follow up. In addition, the case of laser induced CNV treated with intravitreal anti-VEGF injections are reviewed for the first time in literature. A 7-year-old boy presented to our department with blurred vision in his right eye for 2 months. The symptom immediately happened after the boy staring at the laser beam for a few seconds. Examination of ocular fundus with slit lamp showed yellowish lesion in macula in his right eye. CNV was confirmed by fundus examinations, including color fundus photograph, spectral domain optical coherence tomography, fluorescein angiography, and spectral domain optical coherence tomography angiography. After the diagnosis of laser induced CNV, intravitreal ranibizumab (LUCENTIS, NOVARTIS) injection was performed. After 1 injection of intravitreal ranibizumab, the best corrected visual acuity improved from 20/50 to 30/50 and CNV gradually regressed duri...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
