The postoperative course after cataract surgery can be complicated by the formation of severe fibrinous membranes, especially in cases with previous goniotrepanation, after syn echiolysis, iridotomy or iris suturing, and in patients with diabetes or uveitis. This study retrospectively analyzes the efficacy of intraocular tissue plasminogen activator (tPA) for fibrinolysis in these conditions commonly considered as contraindications to tPA therapy. When antiinflammatory therapy was unsuccessful in lysing fibrinous membranes, 10 micrograms of tPA (Actilyse) was injected into the anterior chamber following the first postoperative day (n = 15). In addition, topical corticosteroids and cycloplegics were given postoperatively. Lysis of the fibrinous membranes was achieved in all patients. However, in three cases lysis was incomplete or recurred. Complications of intraocular tPA therapy consisted of mild hyphema (n = 1) and transient dysfunction of the corneal endothelial cells (n = 2). In conclusion, the results suggest intraocular low-dose tPA as an effective approach for the treatment of severe fibrinous membranes after cataract surgery even in high-risk patients.

In the current study, we dosed didecyldimethylammonium chloride (DDAC) in mice by pharyngeal aspiration for 28 days or 90 days (weekly) and tried to elucidate the relationship between lamellar body formation and the lesions. When exposed for 28 days (0, 5, 10, 50, and 100 μg/head), all the mice in the 50 and 100 μg/head groups died since Day 2 after the third dosing (Day 16 after the first dosing). Edema, necrosis of bronchiolar and alveolar epithelium, and fibrinous exudate were observed in the lungs of all the dead mice, and chronic inflammatory lesions were observed in the lung tissues of alive mice.

Purpose: This study examined six patients with Vogt-Koyanagi-Harada (VKH) disease using retromode infrared scanning laser ophthalmoscopy (RMI-SLO).
Methods: We conducted a single-center retrospective review of the medical records of six patients diagnosed with VKH disease. The RMI-SLO images were compared to those obtained using color fundus photography, optical coherence tomography (OCT), and dye-based retinal angiography.
Subconjunctival trypsin injection for anterior chamber fibrin exudates in eyes with globe rupture following vitrectomy.

Article Synopsis
- The study aimed to compare the safety and effectiveness of subconjunctival injections of trypsin versus dexamethasone (DEX) for treating fibrin exudates in patients after globe rupture repair.
- A total of 52 patients were treated with either trypsin or DEX, with results indicating that both treatments led to similar levels of exudate absorption, but trypsin had a quicker absorption time and was less irritating for patients.
- Overall, trypsin was found to be a more comfortable treatment option than DEX, with no adverse effects reported and stable intraocular pressure.
A Severe Case of Infectious Necrotizing Anterior Scleritis Caused by after Vitreoretinal Surgery.

Introduction: This report describes a case of necrotizing scleritis caused by infection soon after vitreous surgery, which caused severe scleral melting and rapidly progressive necrosis that led to scleral perforation and bacterial endophthalmitis.
Case Presentation: The patient was an 86-year-old man with a history of type 2 diabetes mellitus who underwent pars plana vitrectomy (PPV) for vitreous hemorrhage in his right eye. On postoperative day 10, he complained of severe ocular pain and was found to have conjunctival edema and eyelid swelling, which was treated by topical and general systemic antibiotics.

Objective: Malignant pericardial effusions are associated with a poor prognosis. Pericardial fluid cytology and pericardial biopsy are the primary methods for diagnosis. This study aimed to conduct a multi-institutional analysis to compare the diagnostic sensitivity of cytology and biopsy, and to investigate potential explanations for false-negative results in cytology.
