Patient: Description of condition (onset, main symptoms, hospital visited, etc.): Blurred vision due to cloudy glass bulb caused by diabetes. I have suffered from diabetes for many years and suspect it is a complication of diabetes. How should I treat it? Zhou Yingming, Ophthalmology Department, Shanghai Ruijin Hospital: The probability of developing fundus lesions after years of diabetes is very high. You can dilate the pupil to check the fundus to rule out cataracts and glaucoma and other lesions such as retinal degeneration and fissures, and do fluorescence imaging to clarify the cause. Cataract and glaucoma can be treated surgically, retinal degeneration and fissure can be treated with laser if there is no retinal detachment, and if diabetic retinopathy is identified, laser and surgery can also be performed.
