Intracameral anesthesia: in vitro iris and corneal uptake and washout of 1% lidocaine hydrochloride.
OBJECTIVES To characterize the uptake, washout, and metabolism of lidocaine hydrochloride in the iris/ciliary body and cornea. METHODS Iris/ciliary body uptake of lidocaine hydrochloride was measured by incubating human and rabbit irides in radiolabeled carbon 14-1% lidocaine hydrochloride for 2 to 60 minutes. Washout was determined by incubating the iris in 14C-1% lidocaine hydrochloride for...
OCULAR albinism is a form of incomplete albinism in which the lack of pigment is chiefly confined to the eyes. The condition is relatively rare, but since it was described for the first time by Nettleship (1909), it has occasionally been demonstrated in various families. Nettleship was aware that the disease-producing gene was sex-linked, but assumed it to be recessive; recent investigations ha...
OBJECTIVE To collaborate with multiple centers to identify representative epidemiological, clinical, and pathologic characteristics of melanoma of the iris. This international, multicenter, Internet-assisted study in ophthalmic oncology demonstrates the collaboration among eye cancer specialists to stage and describe the clinical and pathologic characteristics of biopsy-proven melanoma of the i...
purpose: to report a case of hermansky-pudlak syndrome (hps). case report: a 7-year-old boy presented with marked generalized hypopigmentation, eye deviation and nystagmus. in addition he had history of easy bruising. visual acuity was 20/200. he had markedly translucent green irides, hypermetropic astigmatism, horizontal nystagmus and marked exotropia. funduscopy revealed a hypopigmented retin...
Uveal melanoma represents the most prevalent form of primary malignant intraocular tumor in adults. Historically, enucleation was considered gold-standard approach treatment uveal melanoma. Currently, radiotherapy is commonly used therapy, aiming at a better quality life. However, can result several ocular complications, some which may be vision-threatening. Radiation-induced dry eye, scleral n...
Aneurysms on new-formed pre-papillary and pre-retinal vessels in proliferative diabetic retinopathy.
RETINAL micro-aneurysms were observed histologically by Mackenzie and Nettleship as early as 1879. However, these observations passed unnoticed until 1943 when Ballantyne and Loewenstein found numerous spherical micro-aneurysms on the capillaries in flat histological sections of retinae from diabetics. These microaneurysms were conceived to be the histological substrate for the small sanguinole...
