Background:Retinitis pigmentosa (RP) is a genetically and clinically heterogeneous group of progressive retinal degenerations with an overall incidence of 1 in 3500-4000 in the general population.
Seven, fourteen days after local BTA application, the degenerations of glandular epithelium and canal epithelium were observed in nasal mucosa of guinea pigs.
Then subretinal fluid was drained away with sclerotomy and choroidotomy under surgical microscope and the location of retinal breaks and degenerations were determined with scleral indentation and cryoretinopexy through sclera.
Both peptides prevent degeneration of Purkinje cells of rat cerebellar vermis upon chemical hypoxia induced by sodium azide in vivo; this effect is also observed on a behavioral level.
In abetalipoproteinaemia, an autosomal recessive condition, vitamin E deficiency results in a progressive spinocerebellar syndrome associated with peripheral neuropathy and retinitis pigmentosa.
Blindness from retinal diseases, including age-related macular degeneration (AMD) and retinitis pigmentosa (RP), usually causes a significant decline in quality of life for affected patients.
Our data on BPA disposition in DA/Han rats are discussed in the context of other kinetic studies with BPA in pregnant rats, and in relation to the previous results from our laboratory (Degen et?al.
In this paper, we prove the degenerations of Schubert varieties in a minusculeG/P, as well as the class of Kempf varieties in the flag varietySL(n)/B, to (normal) toric varieties.
Pick's disease may be distinguished from presenile degenerations, especially from Alzheimer's disease, by pointing out the succession of the early symptoms.
Histopathologic examination of the epidermis showed,in cases of intra-dermal epithelioma,eccrine poroma,clear cell acanthoma and epidermodyspla-sia verruciformis,clumps of heteromorphic epidermal cells with specific features.The authors pointed out that in some of these cases, the clinical signs are not remarkable, however,the histopathological changes are quite distinct between eccrine poroma and eccrine poroepithelioma,or between epidermodys-plasia verruciformis and verruca planus.The authors stated that ...
The characteristics of scotopic ERG in 76 patients(151 eyes)with retinitis pigmentosa were studied.All of them showed abnormal patterns, 84.8% extinguished and 15.2% subnormal.It is demonstrated that extinguished ERG is the main electrophysiological characteristic of this disease.The relations between the changes of scotopic ERG and dark adaptation,of scotopic ERG and visual field and of scotopic ERG and color vision were analysed.
There were 3,162 eyes treated with keratoplasty in Eye Hospital,Zhongshan Oph- thalmic Center from 1965 to June 1985. The leading corneal diseases for keratoplasty, amounting to 85.9% of the total number of kerato- plasty,were herpes simplex keratitis,bacterial or fungal corneal ulcer,chemical and thermal burns and Mooren's ulcer.The less frequent indications were traumatic corneal scarring,corneal dystrophies,and degeneration.Bullous keratopathy and keratoconus were extremely rare. In cases of penetrating ...
自1965—1985.6中山眼科中心眼科医院共对3162眼施行角膜移植。最常见的角膜移植的适应症依次排列是:单纯疱疹角膜炎(活动期与静止期),细菌或真菌性角膜溃疡(炎症期或疤痕期),化学伤与热烧伤和蚕蚀性角膜溃疡,以上共占角膜移植总数的85.9%。比较少的是外伤性角膜白斑、角膜营养不良与变性。大泡性角膜病变、圆锥角膜等极为少见。从1965年至1974年,在穿透性角膜移植的病例中,细菌或真菌角膜溃疡(炎症期或疤痕期)占45.3%-68.4%;自1975年以后,其所占比例明显下降,至最近五年只占26%。与此相反,单纯疱疹角膜炎所占比例则逐年上升,至1976年以后,占穿透性角膜移植病例的45.1%-45.5%。1979年前,板层角膜移植术式较常用,近五年施用板层角膜移植的病人减少,而施行穿透移植的病人增加到70%。板层角膜移植主要用于治疗或为穿透性角膜移植作准备。所以在板层移植的适应症中,蚕蚀性溃疡占首位,化学烧伤居第二,感染性的慢性角膜溃疡或后遗的角膜疤痕占第三位。1979年以前,植片的直径以5.5-6.6 mm 居多,自1980年后,较多采用7-8mm,占50.8%。本文还简述了我院用板层角膜移植治...
