Risk of TED Emerges After Cataract Surgery

Thyroid eye disease is an inflammatory disorder that can affect a patient’s vision quality and lifestyle. Recent evidence on the association between the disease and cataract surgery emphasizes the importance of monitoring patients who undergo treatment for the clouded lens.

In some cases, a procedure may exacerbate a complication or trigger the development of a new condition, so staying knowledgeable on how different treatments affect different diseases and disorders can be important. Recently, Texas-based researchers found that patients with underlying thyroid disorders are more likely to develop eye inflammation following cataract surgery compared to those without preexisting conditions. Their paper was published in Ophthalmic Plastic and Reconstructive Surgery.“There remains a significant knowledge gap regarding the risk of thyroid eye disease following cataract surgery,” said the researchers in their paper. “To date, evidence on this topic has been limited to individual case reports and small case series. In the present study, we aimed to address this gap.”For their study, the researchers examined a larger sample of electronic health data records. They identified an even number of patients who underwent cataract surgery with and without an underlying thyroid disorder: 87,179 pairs in all. In addition to observing the risk of thyroid eye disease following surgery, the team conducted a secondary analysis on patients with hyperthyroidism. There were 8,381 patients in both the hyperthyroid disorder group and the cohort. Health data was analyzed at three time periods: day of surgery to three months, three to six months and six to 12 months.Risk ratios were calculated to determine the risk of thyroid eye disease following cataract surgery compared between the two groups. Across all three time periods, the thyroid disorder groups had a significantly higher risk compared to the cohort. From the day of surgery to three months, the thyroid disorder group’s risk ratio was 1.3. At three to six months, the risk ratio was at 1.3. Last, at six to 12 months, the risk ratio rose to 1.51. Researchers reported a more pronounced risk for patients with hyperthyroidism, reaching a 103% increased risk at six to 12 months.“Further research is needed to elucidate the precise mechanisms guiding clinicians in both preventing and managing this potential complication,” concluded the authors in their paper. “For instance, future prospective studies could measure serum levels of thyroid autoantigens before and after surgery to test the hypothesis of antigen spreading, while translational studies could analyze orbital fibroblasts to identify if the local inflammatory cascade is upregulated after the procedure.” Even in the absence of more conclusive studies, the researchers believe that by recognizing cataract surgery as a potential trigger, eye doctors and endocrinologists “can better counsel patients, optimize perioperative management and ensure prompt intervention, ultimately improving outcomes for this at-risk population.”Click here for the journal source.  Muayad J, Ahmed M, Malik A.
