Newborns with clear raised membranes at the edge of the black eye are usually considered to be due to conjunctivitis, corneal clouding or fundus lesions. 1. Conjunctival lesions: If the newborn has been exposed to pollen, dust, or when rubbing the eye with force where a foreign body has entered, allergic conjunctivitis can result and conjunctival edema can occur. 2. Keratoconjunctival lesions: Newborns may have congenital keratoconjunctival lesions or superficial calcium deposits in the cornea, which can cause grayish-white membranous structures to develop. 3. Fundus lesions: it cannot be excluded that fundus tumors or retinopathy may cause grayish-white material deposition on the edge of the black eyeball. In conclusion, the reason for the appearance of transparent raised membrane at the edge of the newborn’s black eyeball is complicated, and the symptom should be promptly consulted for a clear diagnosis.
