Vascular conjunctival tumors are uncommon, usually benign lesions. Here, we report a 65-year-old male who presented with a nasal interpalpebral bulbar firm, oval, and dark-brown and non-mobile conjunctival mass. The systemic and ocular examinations including fundoscopy and gonioscopy were within normal limits. With a diagnosis of conjunctival malignant melanoma (CMM), the patient underwent excisional biopsy, partial sclerectomy, and cryotherapy. Microscopic examination revealed dilated vascular channels filled by red blood cells, separated by fibrous interstitium and no sign of malignancy. Therefore, a diagnosis of conjunctival cavernous hemangioma was made. Our case demonstrates that the conjunctival cavernous hemangioma can mimic malignant conjunctival lesions as well as extrascleral extension of uveal melanoma or uveal prolapse due to scleral necrosis.

The treatment of indirect carotid-cavernous fistula (CCF) poses a unique challenge. Currently, endovascular interventions remain the principal treatment option with high cure rates and acceptable safety profiles. The anatomical characteristics of individual cases determine the optimal vascular access routes (transvenous vs.

Introduction And Importance: A carotid-cavernous sinus fistula is an abnormal connection between the internal or external carotid artery and the venous system of the cavernous sinus. It represents a rare entity, and it is often misdiagnosed due to its overlapping symptoms with other conditions such as cavernous sinus thrombosis or orbital inflammation. Cerebral angiography continues to be the gold standard for diagnosis and surgical planning in patients with CCF, and the endovascular trans-venous approach still represents the primary line of treatment.

Article Synopsis
- - A 22-year-old male experienced progressive swelling and vision loss in his right eye over a month, but displayed no systemic symptoms that would indicate an infection or illness.
- - Imaging suggested benign conditions, but blood tests revealed hematological issues that led to a bone marrow biopsy, confirming acute myeloid leukemia (AML) with a favorable genetic marker.
- - After starting chemotherapy, the patient showed significant improvement in his eye symptoms and vision, highlighting the need for awareness of potential blood cancers in young patients with unexplained eye issues.

An 84-year-old man with a genetically confirmed diagnosis of VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome treated with tocilizumab reported with a 3-day history of left eye pain, conjunctival chemosis and injection, and horizontal binocular diplopia. Examination revealed restriction of left eye ductions in all directions with mild unilateral proptosis. MRI of his brain and orbits demonstrated abnormal enhancement of the left posterior sclera and intraorbital optic nerve sheath, without involvement of the extraocular muscles, cavernous sinus, or optic nerve parenchyma.

Purpose: To describe an upper eyelid swinging approach (U-Swing) that is suitable for the surgical excision of a large benign encapsulated lesions located in the intraconal space superolateral to the optic nerve.
Methods: This is a retrospective case series. The study included a review of five patients' records who had large encapsulated intraconal masses, superolateral to the optic nerve, and who underwent surgical excision with the U-Swing approach in the authors' institute over the last 10 years.
