Purpose: To report a case of gross hematuria in a patient with previously undiagnosed urothelial carcinoma of the right ureter after intravitreal bevacizumab (Avastin) injections.
Methods: In this case report and review of the literature, an 81-year-old woman presented with neovascular age-related macular degeneration in the left eye. She was treated with repeated intravitreal bevacizumab (Avastin) injections. After injection, she reported two episodes of gross hematuria. After disclosing this information to her ophthalmologist, bevacizumab treatment was suspended and the hematuria resolved. Urological evaluation revealed no abnormalities. Approximately 1 year later, treatment with intravitreal bevacizumab was resumed. After three injections, she again reported gross hematuria. Urological evaluation at that time revealed a high-grade urothelial carcinoma of the right ureter. A right nephroureterectomy was performed, and bevacizumab treatment was resumed. She did not report any subsequent episodes of hematuria.
Conclusion: Hematuria has previously been reported with systemic administration of bevacizumab. However, hematuria after intravitreal injections of bevacizumab has not been reported and is most likely occurring as a result of the systemic absorption of the drug. Further investigation of the systemic effects of intravitreal bevacizumab may be warranted.

Purpose: To report a case of corneoscleral juvenile xanthogranuloma (JXG) with progressive anterior segment involvement refractory to topical steroids.
Observations: A 4-month-old male was referred for a new-onset subconjunctival lesion in the right eye. He was found to have a thickened, yellow corneoscleral lesion and hyphema, presumed to be ocular JXG.

Purpose: To report the rare clinical, optical coherence tomography (OCT), and OCT-angiography findings of a visually significant choroidal neovascular membrane (CNV) in the setting of focal choroidal excavation (FCE) in a child.
Methods: Case report and literature review.
Results: A 9-year-old girl with FCE-related central CNV based on clinical findings and multimodal imaging.

Purpose: Intravitreal bevacizumab has been utilized to mitigate radiation retinopathy, yet the potential role of intravitreal melatonin for its prevention remains unexplored. This study aims to evaluate and compare the efficacy of intravitreal melatonin and bevacizumab in preventing radiation retinopathy in an experimental animal model.
Materials And Methods: Twelve healthy male New Zealand white rabbits ( = 24 eyes) received a single 3000 cGy irradiation dose in both eyes.

Purpose: Ozurdex is a dexamethasone intravitreal implant approved for the treatment of macular edema secondary to branch or central retinal vein occlusion, non-infectious uveitis affecting the posterior segment of the eye, and diabetic macular edema.
Patients And Methods: We report a case of an accidental injection of the implant into the crystalline lens, successfully managed by surgery afterwards. The case description is supported by Anterior Segment Optical Coherence Tomography (AS-OCT) images.

Purpose: To evaluate changes in the retinal microvasculature using widefield swept-source optical coherence tomography angiography (SS-OCTA) following three anti-vascular endothelial growth factor (anti-VEGF) loading injections for diabetic macular edema (DME).
Methods: Thirty-four treatment-naïve patients with DME received an initial three loading injections, followed by injections on an as-needed basis. Macular ischemia was evaluated based on the foveal avascular zone (FAZ) area, perfusion density, and vessel density on a 3 × 3-mm SS-OCTA image.
