White membranous material in the eye, consider blepharospasm, pterygium, corneal scarring, cataract, etc. Usually need clinical observation or surgical treatment. 1. Clinical observation: The presence of white membranous material in the white of the eye, mostly blepharospasm, can be considered for clinical observation. If the white membranous material grows towards the corneal surface and even covers the pupil area, it is mostly pterygium. If the pterygium is small, clinical observation is usually considered. If the white membranous material appears in the cornea, it is mostly corneal scar, if it has less effect on vision, clinical observation can be considered. 2. Surgery: If the pterygium is large and even affects vision, timely surgical removal is needed. If the pterygium is large and even affects vision, timely surgical excision is needed. If there is a white membrane in the pupil area, it is mostly cataract, which needs timely surgical treatment.
