https://www.selleckchem.com/products/peg400.html A 5-year-old Japanese boy presented to the emergency room of our hospital because his right eye had been glued shut for 2 h following instillation of cyanoacrylate adhesive. The clinical examination showed redness of the right upper and lower lid skin; the right eyelid margins adhered to each other because of matting of the eyelashes, and crystallized glue was found within the matted eyelashes. The "hook" technique, which separates the eyelids using a blunt-tip device, was performed to separate the lids. The technique seems to be simple and safe for physicians such as ophthalmology residents to use to treat cyanoacrylate-induced adhesion of the eyelids of patients who often first present to their local emergency room as in our case.We report two cases of chronic rhegmatogenous retinal detachment with a nonperfused peripheral retinal area. Case 1 was an 84-year-old woman who presented with a bullous retinal detachment of the inferior retina and a best-corrected visual acuity of 20/500. A small horseshoe tear was detected in the peripheral superior retina. Fluorescein angiography showed a wide area of nonperfused retina in the inferior retina. The retina was successfully reattached by scleral buckling surgery. Case 2 was a 40-year-old woman who presented with a shallow retinal detachment involving the macula. There were multiple retinal breaks at the pars plana that were secondary to blunt trauma. Fluorescein angiography revealed a wide area of nonperfused retina in the inferior peripheral retina. She underwent scleral buckling surgery, and the retina was successfully reattached. Our findings indicate that clinicians should examine the peripheral retina carefully especially with fluorescein angiography to search for nonperfused areas in eyes with chronic rhegmatogenous retinal detachment.Pigment dispersion syndrome and pigmentary glaucoma are two conditions characterized by pigment dispersion originating from the poster
