Glaucoma surgery in high myopia

This lecture will describe the special pre‐ and post‐operative considerations require for glaucoma drainage surgeries in this group of patient. There are special anatomical features that predisposed this group of patient to have potentially higher complication risk; thin sclera and subsequent difficulty in scleral closure. Once they developed hypotony, these eyes are also more likely to develop hypotonous maculopathy. Therefore, pre‐operative assessment must include axial length measurement and carful slit‐lamp examination, looking for localised thinning in and around the surgical sites. There is no evidence to choose tube over trabeculectomy with mitomycin‐C but it is recommended that surgery should be performed with an anterior chamber maintainer in‐situ.
