“Because both conditions are strongly age-related, some individuals with cataract also hit AMD,” wrote Li dynasty Dong, of Stony Brook University School of Medicine in New York, and colleagues. “There has been a long-standing disceptation among clinicians as to whether cataract surgery is contraindicated in eyes with non-neovascular AMD. A field anxiety has been whether cataract surgery increases the venture of advancement to neovascular AMD (an modern modify of the disease involving manufacture of newborn murder vessels) in eyes at venture of advancement much as those with grey AMD.”
In this study, the researchers examined 71 eyes of patients with non-neovascular AMD before, and at digit hebdomad and digit assemblage after they had cataract surgery. After digit hebdomad of follow-up, fivesome eyes showed signs of neovascular AMD. But the researchers said the filler and positioning of the neovascular AMD lesions declare they haw hit been inform before surgery but couldn’t be perceived cod to the mirky receptor lense caused by cataract.
When these eyes were excluded, advancement to neovascular AMD occurred in 4.6 proportionality of the eyes between digit hebdomad and digit assemblage after cataract surgery, compared with 3 proportionality for cataract-free eyes.
“Our findings declare that preceding reports of the connexion or advancement of non-neovascular AMD to modern AMD after cataract surgery could be biased,” the researchers wrote.
“Subtle signs of neovascular AMD or TRUE atrophy, modify on an angiogram, haw be obscured by lense incomprehensibility meet preceding to cataract surgery,” the aggroup explain. “In much cases, the neovascular disease or the TRUE symptom haw advance to the individual’s exteroception loss, and this haw erroneously be ascribed to the cataract and advance to a selection to travel with cataract surgery.”
Dong’s aggroup concluded: “Our findings do not hold the concept that cataract surgery accelerates the advancement of AMD.”
The think results are publicised in the Nov supply of the book Archives of Ophthalmology.
