Periorbital dermoid cysts are benign tumors most often seen in young children. Intraorbital location, though rare, should not be overlooked. Good quality imaging plays a major role in the etiological diagnosis, providing a precise analysis of the location of the lesion, its components, and its effects on adjacent and nearby structures, as well as in planning the surgical approach. The authors report a case of a 46-year-old male with an intraorbital dermoid cyst presenting with progressive left proptosis. Appearance on imaging (CT and MRI) was consistent with intraorbital dermoid cyst. The tumor was extirpated. Histopathologic examination confirmed the diagnosis of dermoid cyst. We also present a review of the literature.

PURPOSE: The administration of topical tacrolimus (FK506) eye drops or ointment is effective in treating certain immunologic corneal diseases and in the prevention of rejection of high-risk corneal grafts. The purpose of this study is to determine the optimal formulation of tacrolimus 0.06% eye drops. A procedure for preparation is presented and discussed. METHODS: Tacrolimus monohydrate powder and virgin castor oil are used in this new formulation. The manufacturing process guarantees consistency of product sterility. Measurement by high-performance liquid chromatography allows precise control of the concentration of tacrolimus. RESULTS: The manufacture and packaging of tacrolimus 0.06% eye drops involve numerous controls allowing for guaranteed sterility and stability. The drops remained sterile and stabile for 28 days after opening regardless of storage conditions and can be stored for 3 months after manufacture. Tolerability studies are currently being performed.

Ophthalmological involvement in mantle cell lymphoma is rare. An 84-year-old man presented with bilateral proptosis. Orbital biopsy established the diagnosis of mantle cell lymphoma. The diagnosis of mantle cell lymphoma is anatomopathological and immuno-histochemical. Orbital involvement is found most often in advanced stages of the disease, but may be the presenting sign as in the case of our patient. Treatment has improved with the use of rituximab, especially in elderly patients not eligible for autologous hematopoietic stem cell transplant.

Immune-related adverse events (IRAEs) are rare but serious adverse events that may be associated with inhibitors of few immune control points. The purpose here is to report the case of an inflammatory ocular disease, potentially linked to the immunity and use of nivolumab, a new immunological agent used for the treatment of a solid tumor. In spite of the involvement of this treatment in the onset of inflammation, we must always seek another cause. It is possible to continue this treatment by considering the benefit/risk balance for each patient. Close collaboration between oncologists and ophthalmologists is necessary in the diagnosis and rapid management of these IRAE ocular related to these new emerging therapies.

This is a retrospective case series of three patients presenting with syphilitic chorioretinitis. The diagnosis of syphilis rests on the ophthalmologic clinical exam as well as serologic confirmation. We studied the en face and SD-OCT images upon first consultation and after one month of antibiotic treatment with penicillin G.
