Overview
Macular oedema refers to an accumulation of intraretinal fluid within the macula. It is characterised on OCT by the presence of hypo-reflective cystic spaces.
Macular oedema can have a wide range of causes which can be grouped into tractional, toxic, traumatic, tumour related, iatrogenic, inflammatory, dystrophic and vascular causes.
Iatrogenic causes include cataract surgery, vitrectomy, epiretinal membrane peel, retinal detachment repair, pan retinal photogcoagulation, YAG laser capsulotomy and cryotheraphy.
Toxic causes include drugs such as prostoglandins, timolol, epinephrine, vitamin B3, tamoxifen, Interferon, thiazolidinediones and docetaxel.
