Ocular adnexal lymphoma presenting with visual loss

Context: Elderly patients with visual loss often have age-related macular degeneration, diabetic retinopathy, glaucoma, and cataract as common causes of visual loss. Other less common etiologies should be considered, especially in those presenting with systemic associations. Case Report: The patient discussed in our review is an 80-year-old female, with a history of diabetic retinopathy and macular degeneration who presented with a sudden deterioration of vision. While this was initially attributed to diabetic retinopathy, she was eventually noted to have a salmon patch lesion in her conjunctiva, diagnosed on biopsy to be a diffuse large B-cell lymphoma. Conclusion: Because of the significant rate of disseminated disease among patients with lymphomas in the orbit that carries a worse prognosis, early diagnosis is essential to promote better overall survival of these patients. We describe here a patient diagnosed with conjunctival lymphoma associated with pronounced visual loss and review the literature on this subject.
