BackgroundTo describe a peculiar case of concurrent non-arteritic anterior ischemic optic neuropathy (NAION) and cilioretinal arteries occlusion (CLRAO) without other causative agents which responded well to intravenous and intravitreal injection of corticosteroids.Case presentationA 41-year-old woman presented with painless vision loss in the right eye for 1 week. Fundus examinations showed marked disc swelling, flame-shaped hemorrhage over the superior nerve fiber area, and well-demarcated retinal ischemia superior to the fovea in the right eye. Under the impression of NAION with branch retinal artery occlusion, the patient was treated with intravenous and intravitreal injection of corticosteroids. Two months later, as the disc swelling and retinal ischemia resolved, we found that the occluded artery was the cilioretinal artery and not the ordinary branch retinal artery.ConclusionsCLRAO may be concomitant with the setting of NAION, the physicians should be aware that CLRAO may be misinterpreted as BRAO owing to profound disc edema during the early stages of the disease.

a b s t r a c tWe present the case of a 46-year-old man who complained of progressive right lower eyelid swelling associated with diplopia when looking down. A nontender mass over the right lower palpebral conjunctiva with vessel engorgement and limited downward gaze were found. Magnetic resonance imaging (MRI) demonstrated a well-defined nodular lesion occupying the inferior area of the orbit. After surgery, a pathological examination revealed that the lesion was a well-encapsulated fibrous tumor composed of spindle cells with a whorl-like arrangement and collagen formation. Immunohistochemical staining was positive for vimentin, CD34, and CD99. The Ki-67 level was relatively low, diagnostic of a solitary fibrous tumor. Our case showed a typical presentation of an orbital solitary fibrous tumor with slow progression, MRI images of a homogenous isodense lesion in T1, heterogeneous isodense lesion in T2, and positive vimentin, CD99, and CD34 on cytological analysis. This case shows that a combination of history, radiology, and pathology results is crucial to differentiate soft-tissue tumors in the orbit.

We report a case of herpetic endophthalmitis following cataract surgery. A 65-year-old man underwent uneventful phacoemulsification and vision improved within the first few postoperative days. However, visual loss with an anterior chamber reaction of ++++ and a ++ vitreous cell were noted in the 4th postoperative week. Repeated intravitreal injection of vancomycin and ceftriaxone, pars plana vitrectomy and removal of the intraocular lens (IOL), and the capsular bag were performed sequentially but in vain. Bacterial, mycobacterial, and fungal culture of the IOL and capsular bag demonstrated negative findings. Pathological examination revealed no pathogen but a number of mononuclear cells and several multinuclear giant cells. Serology exam revealed positive herpes simplex virus immunoglobulin (Ig)M and IgG. The intraocular inflammation resolved soon after changing antibiotics to oral valcyclovir.
