New study finds food eaten by millions can cause vision loss – ‘unlikely to be restored’ – Express

Three specialised ophthalmologists, including Professor Smith, assessed the scans for toxoplasmic retinochoroiditis, with positive cases confirmed with antibody blood tests.

“Among the 5000 people, we found eight participants with blood test-confirmed toxoplasmic retinal scars. Add to that about three-quarters of the retinal lesions would be in a position not visible in these particular photographs, we were able to estimate the prevalence of ocular toxoplasmosis to be one per 149 persons,” Professor Smith said.

The professor continued: “While there is no cure or vaccine, the symptoms of toxoplasmosis vary depending on the age, health and genetics of the infected individual. Many people are asymptomatic, but the most common disease that we see in the clinic is retinal inflammation and scarring known as ocular toxoplasmosis.

“Studies around the world show that 30 percent to 50 percent of the global population is infected with Toxoplasma, but despite knowing that, what we didn’t know was how common the related eye disease was.”
