Inflammatory IRU can be differentiated from active CMV retinitis by the presence of IL-12, less IL-6, and absence of detectable CMV replication.

Purpose: Uveitis is a major visual impairment disease affecting parts or the entire uveal tract and occasionally the sclera, the cornea or the optic nerve. The disease is a major cause of ocular morbidity and blindness in immunocompetent and immunocompromised patients. In this work we analyzed the sensitivity and specificity of realtime PCR to detect the etiological agent from blood, plasma, vitreous and aqueous humor and compared with the diagnostic hypothesis. Methods: Twenty-seven patients (13 male) were studied and Real-time PCR method was used for the detection of herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2), varicella zoster virus (VZV), cytomegalovirus (CMV), Mycobacterium tuberculosis (TB) and Toxoplasma gondii (Toxo) in the aqueous humor as well as in the vitreous, blood and plasma. Results: Our results showed the presence of Toxo, CMV, VZV or HSV-2 in 19.2% of aqueous humor samples, and in 30% of vitreous humor samples. In plasma and blood samples, only CMV was detected (11.1% and 3.7%, respectively). Conclusion: Real-time PCR was able to detect and to confirm diagnostic hypothesis in uveitis. Our data also confirms that vitreous humor is the best source for molecular diagnosis of infectious uveitis but indicates aqueous humor samples that are easier to obtain may also be appropriate to be tested by Real-time PCR.

To present the full clinical spectrum of the acquired immunodeficiency syndrome-related intraocular lymphoma as manifested in the eye, specifically retinal lymphoma associated with primary central nervous system lymphoma, isolated ocular lymphoma, and choroidal lymphoma associated with systemic lymphoma. Methods: Three patients with acquired immunodeficiency syndrome were noted to have atypical retinal lesions. Diagnostic retinal biopsy in 2 patients and postmortem examination of the eyes in the third case were performed. Results: Diagnostic retinal biopsy in the first 2 patients revealed retinal B-cell lymphoma. Initial systemic evaluation showed the eyes to be the sole site of disease. Later,

Autofluorescence imaging and SDOCT are useful noninvasive methods for the evaluation of serpiginous choroiditis. Autofluorescence imaging allows identification of recurrences and retinal pigment epithelium involvement in the follow-up of this disease.

Retinal nerve fiber layer thinning was related to VF sensitivity loss in human immunodeficiency virus-infected patients and regional associations between optical coherence tomography and FDT Matrix sectors were stronger than the associations between global measurements.

AG3340 administered systemically significantly inhibits oxygen-induced retinal neovascularization in an animal model and appears to be a promising candidate for the treatment of neovascular retinal diseases.
