Cystoid macular edema (CME)


Cystoid macular edema:
Cystoid macular edema is a painless disorder which affects macula (central part of retina). This condition is due to accumulation of multiple areas of fluid as cysts in the macular area.

Cause: A variety of diseases are affected with this condition including retinal vein occlusion, uveitis (inflammation of the middle coats of the eye), and diabetes or after cataract surgery.
Symptom: Blurred or decreased central vision
Dilated Fundus examination: Edema or elevation of the macular area is seen on dilated Fundus examination.
Optical coherence tomography: The retinal section shows the presence and the height of elevation
Treatment: The factor causing the macular edema should be treated. Usually topical NSAIDS are the first line of management in CME systemic carbonic anhydrase inhibitors may be added to this, however if inadequate response is noted posterior subtenontriamicinolone may be considered and in resistant cases Intravitrealtriamicinolone or anti VEGF injection may be considered. If the cause is due to vitreous pull Vitrectomy is done to remove the insult.
