Link Between COVID-19 and Endophthalmitis Found

 

A possible link between COVID-19 and endophthalmitis has been suspected for quite some time; now, researchers have established a connection between the two diseases, with a further investigation being conducted.

In only two months, three COVID-19 patients in New York’s Northwell Health Hospital succumbed to extreme vision loss from keratitis. Endophthalmitis resulted, and in one instance, a patient’s eye was removed. This occurrence of keratitis leading to endophthalmitis is exceedingly rare. Typically, cases of endophthalmitis from keratitis are associated with trauma or surgery.

The American Academy of Ophthalmology 2020 virtual conference released the findings. Researchers hope to gain more support from the medical community to conduct eye evaluations when assessing the role of anti-infectious treatments.

All three endophthalmitis patients were in their 60s, reside in the same relative area, and showed signs of the disease within a two-month period, while testing positive for COVID-19. Two were outpatients, and one was an in-patient at the time of diagnosis. One of the outpatients later passed away in a hospital. The culture results all came back from each individual with different organisms: Streptococcus pneumoniae, Serratia marcescens, and Candida parapsilosis.

A 2012 study reported that out of 9,934 eyes, only 27 throughout a 15-year period experienced endophthalmitis stemming from keratitis. Having three patients express symptoms while being diagnosed with COVID-19 is alarming, and suggests an association between the two.

Sonal S. Tuli, MD, said, “The findings do not suggest that COVID-19 causes endophthalmitis but that there is some relationship between the two. It is possible that some aspect of the health of these individuals made them more liable to get infected with COVID-19 as well as a severe infection in their eye, such as poor immune system or nutritional deficiencies. It is also possible that these findings are incidental because of the large numbers of COVID-positive patients presenting to New York hospitals during the peak of the pandemic.”

Age-Related Macular Degeneration Linked to Air Pollution

 

The University College of London revealed their study findings that showed a link between air pollution and a heightened risk of Age-Related Macular Degeneration (AMD.)

The most polluted areas tested in the study were at least eight percent more likely to report people having AMD. The leading cause of irreversible blindness among people over 50 in high-income countries is AMD. The projected amount of people affected by 2040 is 300 million. Some risk factors include old age, smoking, and genetic composition.

Brain conditions such as Alzheimer’s disease, Parkinson’s disease, and strokes have been implicated in those who breathe poor air conditions as well. In 2019, a study found air pollution was linked to an elevated glaucoma risk.

Professor Paul Foster, a lead author of the UCL Institute of Ophthalmology study, said, “Here we have identified yet another health risk posed by air pollution, strengthening the evidence that improving the air we breathe should be a key public health priority. Our findings suggest that living in an area with polluted air, particularly fine particulate matter, or combustion-related particles that come from road traffic, could contribute to eye disease. Even relatively low exposure to air pollution appears to impact the risk of AMD, suggesting that air pollution is an important modifiable risk factor affecting risk of eye disease for a very large number of people.”

The research was conducted with participants who were asked to report any formal doctor-diagnosed AMD. Structural changes in the thickness and/or numbers of light receptors in the retina were assessed in the participants using retinal imaging.

People in areas with high levels of fine particulate matter pollution were higher on the AMD scale. Even after taking other factors such as underlying health conditions and lifestyle, air pollutants (except coarse particulates) were associated with retinal structure changes. 

Though the study cannot confirm cause, as cautioned by the researchers, their findings align with evidence found worldwide. Ambient air pollution might be a culprit, through oxidative stress or inflammation.

Dr. Sharon Chua, of the UCL Institute of Opthamology, said, “Higher exposure to air pollution was also associated with structural features of AMD. This may indicate that higher levels of air pollution may cause the cells to be more vulnerable to adverse changes and increase the risk of AMD.”
