In a case-control study of 212 white patients with primary melanocytic tumors of the iris and two control groups, contingency tables were used to evaluate the distribution of iris color. We found a strong association between light iris color (blue, gray, or green) and the presence of iris melanocytic lesions (P less than .001 by chi 2). 相似文献

Iris prolapse has become an unusual and generally benign event in routine cataract surgery using endocapsular phacoemulsification techniques. We operated on the second eye of a patient with hyperopia whose first eye surgery in our care had been uneventful. In the second eye, as soon as the phaco incision was made and hydrodissection begun through the primary incision, the iris repeatedly prolapsed through the incision. This was managed definitively by applying iris hooks, 1 at each side of the primary incision, to the pupillary border so the prolapsing iris was held peripherally in the anterior chamber and under modest tension. 相似文献

PURPOSE: To evaluate the safety and efficacy of surgical implantation of prosthetic iris devices in patients with iris deficiency. METHODS: Nine patients with traumatic iris defects, congenital aniridia or iris coloboma, and surgical or optical iridectomies were included in a noncomparative case series. Cataract surgery with intraocular lens and prosthetic iris implantation was performed in 10 eyes. The visual acuity, subjective degree of glare disability, postoperative anatomic results, and intraoperative and postoperative complications were evaluated. RESULTS: The mean follow-up was 17.75 months (range 4-48 months). Best-corrected visual acuity improved in nine of 10 eyes (90%) and remained unchanged in one eye. Glare subjectively improved in four of five eyes (80%) of patients complaining of glare preoperatively. All eyes achieved the desired anatomic result. Intraoperative complications included one anterior capsular tear. Postoperative complications included a short period of mild postoperative anterior uveitis in four eyes. Secondary glaucoma was absent. CONCLUSION: In patients with iris deficiency, implantation of prosthetic iris device, and intraocular lens implant following cataract surgery appears to be safe and effective in reducing glare disability and improving visual outcomes. 相似文献

无虹膜或虹膜大部分缺损眼硅油填充时,往往出现硅油和角膜内皮接触,导致角膜变性、混浊和眼压升高等并发症。为了避免这些并发症的发生,通常植入人工虹膜隔来代替虹膜。本文就人工虹膜隔的类型、形态、优缺点、植入方法、目前的治疗效果及原因等进行综述。 相似文献

Summary Suturing of traumatic or surgical iris wounds has proved to be a safe and feasible microsurgical procedure. Various suture materials have been tried experimentally and clinically. If the human iris forms scar tissue the ideal suture would be an absorbable, inert, proteinfree material causing no uveal reaction. It was the purpose of this study to evaluate the ocular tissue reaction to nylon, virgin-slik and polyglycolic acid (Dexon®) after suturing of an experimental iridomy in 24 rabbit eyes. The tissue response was studied by biomicroscopy, iris fluorescein colour angiography, and histology. Nylon did not disintegrate and caused virtually no inflammatory reaction. Silk showed fragmentation and complete absorption after four to six months with moderate tissue response. Polyglycolic acid gave rise to a marked uveal reaction and depolymerised from the fifth to the sixth week. There was no wound dehiscence of the iris scar and the pupillary function remained intact. It is concluded that the non-absorbable materials are superior to the currently available absorbable sutures in iris surgery. 相似文献

A case-control study of 78 white patients with primary cysts of the iris was undertaken. Two control groups were established for comparison with the subjects. Contingency tables were used to evaluate the distribution of iris color among subjects and controls. Statistical testing (chi 2) indicated no significant association of iris color with the presence of a primary iris cyst (P greater than .05). These results indicated that primary iris cysts do not exhibit the association with light iris color previously documented for iris melanocytic lesions. 相似文献
