- 3. DEFINITION •Digital Eye Strain(DGE) Also referred as Computer Vision Syndrome (CVS) •A group of eye- and vision-related problems result from prolonged computer, tablet, e- reader, and cell phone use
- 4. PREVALENCE OF DGE/CVS •80% American adults report using digital devices for more than two hours/day • 59% report experiencing symptoms of DGE
- 5. PATHOPHYSIOLOGY When work ona digital device, the eyes have to •focus and refocus continously •Move back and forth as one read and likely have to look down at papers or other devices and then back up to the screen •Constantly reacting to images moving and changing, shifting focus, sending rapidly varying images to the brain, and its worsen with add contrast, flicker, and glare •Less frequently blink
- 6. RISK FACTORS •Spend afew hours a day at a computer or on a digital device •Viewing computer/digital device screen at an improper distance/angle •Poor posture while using the computer/digital device •Inadequate lighting causing increase glare from digital device •Don’t take breaks while working •Have vision problems not fully corrected with glasses or contact lenses (even minor changes in prescription) •Don’t blink frequently enough while using the digital devices
- 7. SYMPTOMS •Eye fatigue/tired eyes •Headaches •Tearing •Blurry vision/double vision •Eyediscomfort •Dry eyes/ itchy eyes / irritation •Neck pain / shoulder pain Symptoms may vary in frequency, severity, and quantity
- 9. TREATMENT Change how to usethe computer
- 10. TREATMENT Location of computer screen center of the screen 4- 5 inches below eye level 20-28 inches from the eyes
- 11. TREATMENT Lighting position the screento avoid glare (from overhead lighting or windows) Anti-glare screens Consider using screen glare filter, if there is no way to minimize glare from light sources
- 12. TREATMENT Seating position chairshould be comfortably padded and comfort to the body Chair should be adjusted so the feet rest flat on the floor
- 13. TREATMENT Rest breaks 15 minutesafter 2 hours of continous computer use 20/20/20 rule Blinking Effort to blink frequently Use artificial tears
- 14. TREATMENT Adjust the devices raise the contrast make text larger Change brightness: lighter/darker than the surroundings Lower the color temperature, giving less blue light
- 15. TREATMENT Correct the refractiveerror properly

Editor's Notes
- #1 Good morning, fellow, consultant and senior residents, I’d like to present my literature review entitled… from Neuro-ophthalmology division
- #3 Based on search results using keywords stated above, articles were considered eligible to be reviewed if the studies met the following inclusion criteria such as neuromyelitis optica that threated with azathioprine, mycophenolate mofetil, rituximab, or combinations between those drugs as preventive/maintenance therapy. The cases with primary attack of NMO and in pregnancy patient were excluded. The article that not published in English and not accessible full paper was also excluded. Publication date was restricted to five years (2014-2019). Selected articles were further screen by reviewing the content manually and chosen based on relevant study outcomes. The information extracted from each study included the authors of each study, the year study was reported, information on the study design, duration of the study, and number of subjects.
- #4 The prevalence of NMO varies considerably across studies (3–57 per million population).10 In North America, Australia, and Europe, NMO patients represent a small fraction (1%–2%) of Caucasians with inflammatory white matter disease; However, in Asia and the West Indies, the percentage rises to almost 50% of demyelinating disorders. With majority of female (80-90%) in most study.
- #5 Based on search results using keywords stated above, articles were considered eligible to be reviewed if the studies met the following inclusion criteria such as neuromyelitis optica that threated with azathioprine, mycophenolate mofetil, rituximab, or combinations between those drugs as preventive/maintenance therapy. The cases with primary attack of NMO and in pregnancy patient were excluded. The article that not published in English and not accessible full paper was also excluded. Publication date was restricted to five years (2014-2019). Selected articles were further screen by reviewing the content manually and chosen based on relevant study outcomes. The information extracted from each study included the authors of each study, the year study was reported, information on the study design, duration of the study, and number of subjects.
- #9 Treatment of NMO includes both the management of acute attacks and the prevention of exacerbations.
