The ciliary bodies from four rhesus monkey and six human eyes were subdivided into eight adjacent zones. The morphology of the ciliary epithelium and bordering stroma at the crests of the processes was examined electron microscopically in each region. In two of the monkey eyes (3 months and 18 years old) and in two of the human eyes (18 years and 55 years(More)
Oxidative stress has been suspected of contributing to the pathogenesis of pterygia. We evaluated the immunohistochemical localization of the markers of oxidative stress, that is, the proteins modified by 4-hydroxyhexenal (4-HHE) and 4-hydroxynonenal (4-HNE), which are reactive aldehydes derived from nonenzymatic oxidation of n-3 and n-6 polyunsaturated(More)
PURPOSE To test the safety and efficacy of topical 1.5% dexamethasone aqueous eye drops with cyclodextrin microparticles for diabetic macular edema (DME). METHODS Nineteen eyes of 19 consecutive patients with DME were administered dexamethasone-cyclodextrin eye drops three or six times a day for 4 weeks and then observed for 4 weeks without treatment.(More)
PURPOSE To report the efficacy of systemic prostaglandin E1 (PGE1) monotherapy for treating acute central retinal artery occlusion (CRAO). METHODS The best-corrected visual acuity (BCVA) and side effects were evaluated retrospectively in 10 consecutive eyes (nine patients; mean age, 61.3 years) with acute CRAO treated with PGE1 monotherapy. The protocol(More)
PURPOSE To compare in a randomized, controlled trial topical 1.5% dexamethasone γ-cyclodextrin nanoparticle eye drops (DexNP) with posterior subtenon injection of triamcinolone acetonide in diabetic macular oedema (DME). METHODS In this prospective, randomized, controlled trial, 22 eyes of 22 consecutive patients with DME were randomized to (i) topical(More)
PURPOSE A possible association has been reported between exfoliation syndrome (EX) and various ocular and systemic vascular disorders; however, it is unclear if there is an association between EX and central retinal vein occlusion (CRVO). Because latent deposits of exfoliation materials might not be recognized during slit-lamp examination, an ocular biopsy(More)
PURPOSE Previous studies have described a possible association between exfoliation syndrome (EX) and various ocular and systemic vascular disorders; however, the association between EX and branch retinal vein occlusion (BRVO) remains unclear. Because slit-lamp examination may overlook latent deposits of exfoliation materials, an ocular biopsy is usually(More)
