Panoptic versus conventional ophthalmoscope

Clinical & Experimental Ophthalmology

The 'ease of use' and accuracy in measurement of the vertical optic cup/disc ratio (VCDR) was compared between the conventional direct ophthalmoscope (CO) and Panoptic direct ophthalmoscope (PO) in a group of 'naïve' first year medical students to determine which would be more suitable for non-ophthalmologists. In this quasi-randomized method comparison study, eight students received an introductory session on ophthalmoscopy then examined 18 eyes (9 left, 9 right) with each ophthalmoscope in a private practice. The subjects were the eight students themselves plus two other subjects. Each subject (n = 10) had one eye dilated. Students determined a VCDR and a subjective score of 'ease of use' on a scale of 1 (difficult) to 10 (easy). A consultant ophthalmologist (GAG) determined the benchmark VCDR for each eye with each ophthalmoscope. Of 288 eye examinations, there were 111 measurements of VCDR using the CO (47 undilated, 64 dilated), and 140 measurements using the PO (75 undilated, 65 dilated). Differences in the students' estimated VCDR and the benchmark were similar for the CO and PO (P = 0.67). 'Ease of use' was scored in 288 eyes and the median score was higher in the PO overall (CO: median 8, IQR 6-9; PO median 9, IQR 8-10...Continue Reading

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

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.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
