I am greatful for your opinion Doc..!!
You sister needs to be under the care of a Eye MD ophthalmologist physician. She shouldnot, in my opinion, be under the care of a non-MD optometrist.
SHe needs exams every 3-4 months and a full glaucoma work up: central corneal thickness measurement, Full exam with IOP, optic nerve photographs, gonioscopy, visual field and optic nerve OCT.
Treatment is with drops and/or laser.
