Toxocariasis
Hi guys! I got curious (and admittedly slightly disgusted) at the idea that a worm could be in the eye from dog feecees so I decided to investigate some more. Apparently it’s called Toxocariasis and it’s an infection that’s caused by the roundworms in the guts of animals. So these animals deposit these roundworm eggs in soil, and when humans accidentally consume these eggs they’re hatched in your intestines. If untreated it can eventually lead to permanent vision loss.
I read the article here: https://www.allaboutvision.com/conditions/infections-allergies/toxocariasis/
Hope this helped anyone else who was slightly curious!

This is just a running theory, Occulation seems correct however I did also want to put this potential diagnosis out there
Diagnosis: This case is most consistent with a ruptured retinal arterial macroaneurysm (RAM), which is a weakened, enlarged area in a blood vessel of the retina that has burst and caused bleeding. The diagnosis is supported by the patient's sudden painless vision loss, the retinal photo showing a large area of hemorrhage (bleeding) near the optic nerve that extends toward the center of vision, and the imaging test showing leakage from a retinal blood vessel in the same area. Another scan shows blood underneath the retina, which explains the severe drop in vision. Retinal arterial macroaneurysms are most common in older adults, especially those with high blood pressure and blood vessel disease. In this case, the retinal arterial macroaneurysm ruptured, causing hemorrhaging under the retina and affecting the area responsible for sharp central vision.
Treatment: Treatment depends on the size of the hemorrhage, how much vision is affected, and whether the retinal arterial macroaneurysm (RAM) is still leaking. Small hemorrhages may simply be monitored because the blood can slowly be reabsorbed by the body over weeks to months. However, in a case like this with severe vision loss and a large amount of blood under the retina, treatment is often considered to prevent long-term damage to the retina. Options may include laser treatment to seal the leaking blood vessel, injections into the eye to reduce leakage and swelling, or in some cases surgery or a gas bubble procedure to move the blood away from the center of vision. It is also important to control high blood pressure and other blood vessel problems because these are common causes of retinal arterial macroaneurysms. The goal of treatment is to stop further bleeding, help the blood clear more quickly, and reduce the risk of permanent damage to the retina and vision.
