Central toxic keratopathy: a clinical case series.

PURPOSE: To describe clinically, a case series of central toxic keratopathy (CTK), and contribute with one possible aetiology of this entity. METHODS: A retrospective observational case series, which included 12 eyes diagnosed with CTK after undergoing laser refractive surgery in situ keratomileusis (LASIK). RESULTS: From a total of 28 eyes that underwent LASIK in the same week, 12 develop CTK. The mean time of the diagnostic was 4 days after surgery. The resolution time had an interval between 1, 3 and 9 months, and an average of 4.6 months. The occurrence of CTK cases coincided with the change of the brand of surgical gloves, and no further cases were found after their replacement. CONCLUSIONS: The CTK clinical findings are well described, but with a yet unknown origin. It seems clear that it does not require specific treatment. It is possible that there might be a relationship between a substance of the gloves and CTK. Further studies are needed to know all the details of this process.

Choroidal metastases from lung adenocarcinoma.

A 32-year-old woman presented with an unknown visual deficit. Fundus examination revealed a lesion compatible with a metastatic focus. Diagnostic workup revealed a lung mass and the biopsy was compatible with lung adenocarcinoma. The intraocular lesion was the only metastatic site at the time of diagnosis. She received local choroidal treatment and further systemic therapy. A pneumonectomy was performed. Five months later she progressed systemically and has since then received several lines of chemotherapy. Choroidal metastases are an infrequent site of systemic dissemination and associated with a poor prognosis, with a median survival of around 2 months if it is the first manifestation of a lung neoplasm. Here we review the literature on choroidal metastases, their treatment options and epidemiology.
