Background: To investigate the effects of preoperative intravitreal injection of bevacizumab (IVB) on the levels of 27 inflammatory cytokines, including interleukins (ILs) and vascular endothelial growth factor.

Methods: From among 200 patients who had proliferative diabetic retinopathy and underwent vitrectomy in our department from September 2009 to October 2010, 8 study subjects met the enrollment criteria in which both eyes at nearly equivalent stages underwent vitrectomy. The first vitrectomy for each patient was performed without IVB (control group), whereas the second vitrectomy on the contralateral eye was performed with IVB treatment (1.

Purpose: To describe the clinical and genetic characteristics of a Japanese family in which one member exhibited Bietti's crystalline corneoretinal dystrophy (BCD).

Methods: Using direct sequencing, mutation screening was performed in the CYP4V2 gene of both the patient with BCD and her daughter. Ophthalmic examinations were performed to determine the clinical features of both subjects.

Purpose: Mycosis of the orbital apex is often fatal. We report case of orbital apex syndrome, which appeared to have been caused by hypertrophic pachymeningitis with positive systemic mycosis antigens treated with systemic corticosteroid combined with antimicrobiotic therapy.

Case: A 57-year-old woman presented with disturbed ocular motility and visual disturbance of her left eye.

Purpose: We report a patient (Case 1) with Bietti crystalline corneoretinal dystrophy (BCD) associated with previously unknown findings of crystal-like deposits on the anterior and posterior lens capsules. This patient is one of four (Cases 1-4) in whom we have found BCD associated with the same mutation in the CYP4V2 gene.

Methods: We present a case report with molecular diagnosis.

Purpose: To report changes in intraocular indocyanine green (ICG) concentration which was used for visualization of the internal limiting membrane (ILM) during vitreous surgery on 3 eyes of 3 patients with full-thickness macular hole.

Methods: During intraocular surgery with ICG-assisted ILM peeling, aliquots of intraocular fluid obtained at 1 min after ICG administration (0.5 ml of 5 mg/ml ICG solution), before and after ILM peeling, and before and after fluid/gas exchange were subjected to spectrophotometric analysis.

Purpose: The effects of various light-induced stresses on the retina were examined in the retinal degenerative rat model.

Methods: Retinal morphology and electroretinograms (ERGs) were analyzed after application of light-induced stress of several intensities (650, 1300, 2500, or 5000 lux). For evaluation of rhodopsin (Rho) function, the kinetics of Rho regeneration and dephosphorylation were studied by spectrophotometric analysis and immunofluorescence labeling with antibodies specifically directed toward the phosphorylated residues (334)Ser and (338)Ser in the C terminus of Rho.

Purpose: To report clinical and immunologic aspects of cancer-associated retinopathy (CAR).

Design: Observational consecutive case series.

Methods: A retrospective review was made of 18 consecutive patients with cancer-associated retinopathy who had antiretinal antibody determination by Western blot testing.
