Metastatic squamous cell carcinoma masquerading as acute retinal necrosis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: To describe a case of retinal and optic nerve metastases masquerading as acute retinal necrosis secondary to primary squamous cell carcinoma of the lung. Observations: A 66-year-old male with a history of Stage IV lung cancer, actively on chemotherapy, presented with right eye vision loss, an afferent pupillary defect, and partial visual field deficiencies. Exam revealed vitritis, macula-involving infiltrative retinitis, optic neuritis, and vasculitis of the right eye. The patient was treated empirically for acute viral retinitis with intravitreal foscarnet and ganciclovir injections and oral acyclovir and trimethoprim-sulfamethoxazole. A diagnostic pars plana vitrectomy with vitreous biopsy, intravitreal antivirals and silicone oil fill was performed. The resulting cytology was positive for malignant squamous cell carcinoma. Conclusions and importance: We present a unique case of primary squamous cell carcinoma metastasizing to the retina and optic nerve which masqueraded as an acute viral retinitis. To date, there have not been any reported cases on Pubmed or Google Scholar at publication time of known squamous cell carcinoma metastases to the retina that demonstrated interval growth leading to emergent elevations in intraocular pressure (IOP). This case demonstrates the importance of considering metastasis when encountering an atypical acute retinal necrosis case, as well as bring awareness to the possibility that elevated IOP may be the first sign of interval metastases, despite surgical debulking, in cases involving known tumor metastases to the retina.
