Hello. Thank you for writing to us.
I shall try to narrate all the possibilities in your case. However it is advised to consult an ophthalmologist for the confirmation and treatment.
According to the symptoms you have described, I understand that you are suffering from myopia that might be pathological. Lacquer cracks represent the regressing or healing breaks in the epithelium of retina, Bruch's membrane. This could be a consequence of degenerative myopia, a condition where the retina separates as a result of abnormal, continues elongation of the eye ball. In this the retina gets thin, and may lead to break down of macula resulting in a vision and floaters.
The drooping of eyelid is a result of Botox treatment. The progressing myopia and the drooping eyelid, changes in your macular area all these suggest an imminent need to consult the eye specialist. The degenerative myopia can be corrected with either sclera buckling or systemic therapy with 7 methylxanthine. I strongly suggest you to make an appointment with your ophthalmologist for early and prompt treatment.
Hope this helps.
