AI Article Synopsis
- Intraocular lymphomas are rare and have a poor outlook, making early diagnosis and treatment essential.
- Two cases are reported involving a 66-year-old woman and a 62-year-old man, both presenting with vision issues and diffuse vitreous opacification.
- Diagnosis was achieved through cytological analysis of vitreous and infusion fluid collected during a surgical procedure, confirming primary lymphoma in Case 1 and metastatic lymphoma in Case 2.
Article Abstract
Purpose: Intraocular lymphomas are rare, and they have poor prognosis. Thus, early diagnosis and treatment are needed. A definitive diagnosis of a lymphoma is based on cytological analysis of the intraocular fluids or tissues. We report two cases of intraocular lymphoma diagnosed by the analyses of vitreous and infusion fluid.
Patients: Case 1 was a 66-year-old woman who complained of eye floaters and was found to have diffuse vitreous opacification bilaterally. She received corticosteroid therapy, however the vitreous opacification was not resolved, and her visual acuity (VA) remained reduced. She underwent pars plana vitrectomy (PPV), and vitreous and infusion fluid were collected to determine the cause of the reduced VA. The undiluted vitreous obtained from core PPV was submitted for cytokine analysis, and infusion fluid was obtained from the machine cassette after full PPV and used for cytological analysis. Case 2 was a 62-year-old man referred with low vision and was found to have diffuse vitreous opacification in the right eye and dot hemorrhages in both eyes. Four years earlier, he had been diagnosed with diffuse large B-cell lymphoma of the paranasal sinuses and was in remission after chemotherapy. Because metastasis of the lymphoma was suspected, he underwent PPV, and intraocular samples were collected as in Case 1.
Results: Atypical lymphoid cells were detected from the infusion fluid in both cases. The ratio of interleukin (IL)-10 to IL-6 was greater than 1.0 in both cases. These results allowed us to make a diagnosis of intraocular lymphoma: primary intraocular lymphoma in Case 1 and metastatic intraocular lymphoma in Case 2.
Conclusion: Vitreous and infusion fluid collected during PPV can be used for diagnosing an intraocular lymphoma.

The ocular tissue is one of the most densely populated tissues in the body with extremely small blood vessels, and vascular lesions have been reported to be a factor in vision loss and visual field defects in many ocular diseases. Currently, vascular endothelial growth factor (VEGF)-targeted agents are the first line of treatment for intraocular vascular lesions, however, there are some cases in which they are not fully effective. Therefore, we explored pathogenic molecules other than VEGF, aiming to develop new molecular-targeted therapy.

Article Synopsis
- A 63-year-old man experienced vision loss in his left eye and blurred vision in his right eye for four months, initially diagnosed as uveitis by an ophthalmology department.
- After further evaluation, he was found to have central nervous system lymphoma, leading to systemic treatment, but his vision continued to deteriorate.
- Eventually, tests revealed intraocular lymphoma in both eyes, and he received eight intravitreal methotrexate injections, resulting in significant improvement in his visual acuity.

Purpose: To report a case of bilateral primary vitreoretinal lymphoma (PVRL) masquerading as endophthalmitis in a patient with a history of bilateral cataract surgery and COVID-19.
Observation: A 60-year-old male patient presented with diminution of vision in both the eyes. There was a history of bilateral cataract surgery done 2 months back at a gap of one week and COVID-19 infection treated with high dose systemic corticosteroids.

Background/aim: Mucosa-associated lymphoid tissue (MALT) lymphomas occur in not only the ocular adnexa, but rarely in the sclera or uvea. Histopathological confirmation contributes to a better understanding of the pathogenesis and treatment. We report a case of uveoscleral MALT lymphoma with angle-closure glaucoma.

Various space occupying lesions can arise in the orbit, ranging from developmental anomalies to malignancies, and many of the diseases occurring in children are different from the pathologies in the adult population. As the clinical presentation is frequently nonspecific, radiologic evaluation is essential for lesion detection and characterization as well as patient management. While orbital masses may in some cases involve multiple compartments, a simple compartmental approach is the key for the diagnosis on imaging studies, and MRI is the modality of choice.
