A histologic examination showed a hemorrhagic necrotic mass in the posterior chamber, surrounded by undifferentiated (immature, undeveloped) glial tissue. The diagnosis included a pseudotumor of the retina, hyperplasia of retinal, ciliary, and iris pigment epithelium, hypoplasia and necrosis of the inner layer of the retina, cataract, and Phthisis bulbi. This means his eye was removed because the physician suspected a tumor, although it emerged that it was a developmental defect that led to the malformation of inner parts of the eye.
