Ten Pearls for The Management of Pseudophakic Corneal Edema

A small, randomized control trial in compared topical ketorolac to topical prednisolone to combination therapy for the treatment of pseudophakic CME. The mechanism of the ridge formation is still unclear with some suggesting distortion of the chamber by sutures and others suggesting edema of the corneal stroma to be the cause. Conclusions: Although newer treatment options have been suggested, penetrating keratoplasty still remains the most definitive treatment and has the highest success rate.

There are multiple risk factors that hypothyroiddism contribute to corneal edema associated increase in the eye pressure after the use of the Nd:YAG laser, such as presence of glaucoma or high eye pressure before the surgery, absence of posterior chamber lens, myopia, laser energy used, etc. Loss of corneal endothelial cells pre-operatively, intra-operatively, and post-operatively are all thought to contribute to the development of irreversible corneal edema in PBK. They may also endorse discomfort and pain, due to the swelling of the epithelium with resultant stretching of corneal nerves or from a ruptured corneal bullae.

Characteristics of patients with CME following phacoemulsification. Currently, pre-operative endothelial cell count and surgical trauma are the most pseudo;hakic factors for the development of PBK. Occasionally, the inflammation produced by cataract extraction can cause contraction of the with hypothyroidism hyaloid face, leading to distortion of parafoveal capillaries and resultant macular edema. With approximately 3 million cataract surgeries performed in the United States per year and heightened patient expectations, it is important for retinal specialists to understand the varied pathogenesis, risk factors and proper management of PCME. Follow-up study of cystoid macular edema following cataract extraction. Corneal cultures should be performed if the keratitis is vision threatening. The incidence of PCME following phacoemulsification in uncomplicated, low-risk patients can vary from 2 percent to 12 percent.

A corneal ulcer is an open sore that forms on the cornea.

Subretinal fluid can also be seen. Post-operatively, various entities can increase risk of developing post-operative corneal edema including but not limited to inflammation and acquired hypothyroidism treatment. Xorneal endothelial cells are damaged, fluid can build up and cause the cornea to swell, clouding vision.
