title: Effects of Disseminated Mycobacterial Infection on Age-Related Macular Degeneration.
abstract: Our patient, in the 7th decade of life, presented with worsening blurry vision over 3 weeks. The pertinent history included nonexudative age-related macular degeneration, recent pulmonary mycobacterial infection, and autoimmune pancreatitis. The patient had decreased visual acuity in both eyes; the remaining findings of our examination were relatively benign. The diagnosis of bilateral exudative age-related macular degeneration was aided by ocular imaging. Not only were exudative changes confirmed, but one modality suggested an underlying occult choroiditis, which presumably fueled a local inflammatory drive leading to evolution of the disease. Given the choroiditis developed in the setting of a recentMycobacterium chelonaeinfection, dissemination of the organism must be considered a potential culprit. Additionally, a chronic inflammatory state perhaps played a simultaneous immunologic role. We feel the proposed pathogenic mechanism outlined sufficiently accounts for the rare event, that is, development of subacute bilateral exudative maculopathy. The patient responded well to bilateral intravitreal aflibercept injections. After 1 month, visual acuity was found to be near baseline and ocular imaging showed significant resolution of the exudative changes. An additional follow-up 3 months after confirmed similar stability. This case required thorough investigation of seemingly unrelated components within the patient's history. We stress the importance of obtaining appropriate documentation from fellow health care teams when suspicious clinical presentations arise. During our investigation, we identified cryptic retinal lesions by way of angiography - leading us to recommend usage of such methods in complex cases. We also summarize the implemented aflibercept course and the favorable response to such treatment.
