超声乳化白内障手术对角膜知觉的影响 总被引:1,自引:0,他引:1
目的 观察颞侧透明角膜切口的超声乳化白内障手术对角膜知觉的影响。方法 随机抽取行颞侧透明角膜切口超声乳化白内障吸出术的老年性白内障患者30例(30只眼),分别于术前、术后1天、术后1、3、6月、术后1年行角膜知觉检查,用Cohet—Bonnet角膜知觉计分别测量角膜中央、上方、下方、鼻侧、颞侧的角膜知觉阈值(以测定器的尼龙丝长度表示)。结果 术后1天全部病人角膜知觉显著减退,中央减少40.4%、颞侧减少39.9%,上方、下方和鼻侧分别减少33%、28.5%、28.7%。上方、下方、鼻侧角膜知觉术后6个月恢复,中央及颞侧角膜切口知觉术后1年恢复。结论 小切口超声乳化白内障手术可影响角膜知觉,但术后角膜知觉恢复较快。 相似文献

Mucopolysaccharidoses (MPS) are a heterogeneous group of rare inherited disorders, characterized by the lack or malfunction of lysosomal enzymes necessary for glycosaminoglycan (GAGs) catabolism, and their subsequent accumulation in many tissues and organs throughout the body. An overview of the current knowledge of corneal and anterior segment manifestations in patients with MPS was provided and clinical guidelines for their diagnosis and management were furnished. The anterior segment of the eye is usually involved in every subtype of MPS, with major complications including varying degrees of corneal opacification and raised intraocular pressure (IOP) with development of glaucoma. Their recognition and management can be very useful in the diagnosis of MPS. Novel techniques are available to objectively measure the grade and extent of corneal clouding and give information about the anatomy of the anterior chamber and the structures of the angle beyond the clouded cornea. It is advisable to take advantage of this new instrumentation in order to obtain thorough information on the ocular involvement and its related anterior chamber complications for a better management of patients with MPS, both in terms of visual prognosis and therapeutic outcome. 相似文献

Case reportA 31-year-old woman who had undergone surgery for a congenital cataract as a newborn developed bilateral malignant glaucoma, which was refractory to medical-surgical treatment. The patient currently has terminal glaucoma and severe band keratopathy. For aesthetic purposes, we performed intrastromal keratopigmentation surgery using ink for skin tattoos supplied in sterile single-dose vessels. No secondary effects or complications were observed.DiscussionKeratopigmentation or corneal tattooing can now be used as a last resort in patients who are unable to tolerate cosmetic contact or intraocular lenses, or in whom corneal transplant is contraindicated. 相似文献

BackgroundThe donor lenticule insertion techniques play a crucial role in outcomes following descemet stripping endothelial keratoplasty (DSEK) and the current study is aimed to compare two of the commonly performed donor lenticule insertion techniques in DSEK.MethodDescemet stripping endothelial keratoplasty was performed in 48 eyes of 48 patients at two tertiary eye care centers from January 2014 to December 2016. At one center (Group 1), 26 patients had Sheets glide-assisted lenticule insertion whereas at other center (Group 2), 22 patients had Busin glide-assisted insertion of donor lenticule. Best corrected visual acuity (BCVA), manifest spherical equivalent, manifest cylinder, endothelial cell density (ECD) and percentage of endothelial cell loss (ECL) were compared between the two groups at 6 months after DSEK. In addition, intraopertaive and postoperative complications were also compared.ResultsAt 6 months after DSEK, an insignificant difference was observed in BCVA [Group 1: 0.48 logarithm of the minimum angle of resolution (log MAR); Group 2: 0.50 log MAR (p = 0.74)], mean manifest spherical equivalent [Group 1: 0.64 diopter (D); Group 2: 0.59 D (p = 0.74)], mean manifest cylinder [Group 1: 1.35 D; Group 2: 1.32 D (p = 0.92)] and mean ECL [Group 1: 26.75%; Group 2: 28.76 (p = 0.44)] between the two groups. In addition, the rate of complications is similar between the two groups.ConclusionsBoth Sheets glide-assisted and Busin glide-assisted donor lenticule insertion techniques are associated with similar surgical outcomes after DSEK. 相似文献

A 53-year-old woman with hemiparesis and poor dexterity, underwent cosmetic blepharopigmentation on the both upper eyelids in the dermatology clinic of a private hospital. She was not asked for any information on her medical history and no informed consent was obtained and the procedure was performed without any protective ocular shields. The patient experienced severe lacrimation, discomfort, and increased sensitivity to light during and after the procedure. She also noticed blurred vision after the procedure. Ophthalmologic examination revealed tender and oedematous eyelids and corneal abrasions in both of her eyes. Topical antibiotics and preservative-free lubricants were able to recover her from her signs and symptoms at 1-week follow-up. It is recommended that cosmetic blepharopigmentation should be applied cautiously with patient’s informed consent after obtaining a thorough medical history and with protective ocular shields to avoid potential complications. 相似文献
