Purpose: To use micro-ribonucleic acid (microRNA) profiles in the vitreous for differential diagnosis of primary vitreoretinal lymphoma and uveitis.
Design: Prospective cross-sectional study.
Methods: This prospective cross-sectional study included 17 diffuse large B-cell primary vitreoretinal lymphoma and 12 uveitis patients. The supernatant of ocular fluid was subjected to total RNA extraction, followed by complementary deoxyribonucleic acid (cDNA) synthesis. Selected samples (primary vitreoretinal lymphoma, n = 3; uveitis, n = 3) were arrayed by a real-time polymerase chain reaction (RT-PCR)-based microRNA panel that detects 168 human mature microRNAs. The markers promising in distinct levels between uveitis and lymphoma were further tested for in all the other 23 samples by individual RT-PCR analysis.
Results: Of 168 microRNAs in the array, 66.5% were detectable with consistent higher microRNA-484, microRNA-197, and microRNA-132 in the primary vitreoretinal lymphoma vitreous and higher microRNA-155, microRNA-200c, and microRNA-22* in the uveitic ocular fluids. The results were normalized by different combinations of 7 control microRNAs (microRNA-103, microRNA-191, microRNA-42-5p, microRNA-16, microRNA-425, microRNA-93, and microRNA-451). After optimization, normalization against microRNA-16 was equally as reliable as the average of the 7 control microRNAs. Individual assays of all samples supported the pattern yielded from the array analysis. But only microRNA-155 was significantly higher in the uveitic vitreous compared to that with lymphoma.
Conclusions: Mature microRNAs are detectable in ocular fluid samples. Primary vitreoretinal B-cell lymphoma and uveitis might be characterized by distinct microRNA signatures. Quantification of ocular microRNA-155 might be helpful in the differential diagnosis of these 2 diseases.

Primary central nervous system lymphoma (PCNSL) is a diffuse, large B-cell lymphoma affecting the brain, spinal cord, leptomeninges, or eyes. A patient with a recurrence of a previous PCNSL manifesting as an isolated vitreoretinal disease without central nervous system (CNS) involvement and a second cerebral recurrence without vitreoretinal involvement has not yet been reported. The patient is an 86-year-old man with PCNSL of the left cerebellum diagnosed at the age of 82 years and treated with suboccipital trepanation and resection of the lesion followed by chemotherapy.

Purpose: To evaluate the potency and security of Pneumatic Vitreolysis (PVL) as the primary treatment for Full-Thickness Macular Holes (FTMHs) and provide insights into patient selection criteria and procedural outcomes.
Patients And Methods: A retrospective analysis of three clinical cases presenting with FTMHs treated initially with PVL was conducted. Cases were evaluated for anatomical and functional outcomes through comprehensive ophthalmic examination and optical coherence tomography (OCT) imaging.

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.

Diabetic vitrectomy is a highly intricate surgical procedure performed during the advanced stages of diabetic retinopathy (DR). It is used to treat conditions such as tractional or combined retinal detachment, vitreous hemorrhage, and subhyaloid hemorrhage, which are all severe manifestations of proliferative DR. The results of the surgery are uncertain and variable.
