Presentation
Early in life, the child presented a developmental delay: crawling at 18 months, sitting at 24 months, speech acquisition after 3 1/2 years. [hindawi.com]
However, spectacles were advised as low vision was present in our patient, and regular ophthalmological follow-up was stressed upon. Accessory digits are often nonfunctional and may be excised. [ijdvl.com]

These may be present at birth or may become noticeable as the child grows. For diagnosis, four primary symptoms should be present, or three primary plus two secondary symptoms. There is no specific test to detect the presence of BBS. [uhb.nhs.uk]

Prevention
There are no proven effective treatments to either prevent or alleviate the deterioration in vision. However, spectacles were advised as low vision was present in our patient, and regular ophthalmological follow-up was stressed upon. [ijdvl.com]
Good diet management can prevent the weight-related problems that manifest in later life. Consulting with a primary care physician and a dietician can help in planning for adequate nutrition and prevention of excess weight gain. [rarediseases.org]
