Eye wall resections for intraocular tumors: Our experience

We conducted a retrospective review of 11 eyes undergoing eye wall resection between October 1998 and October 2009. The median age of 11 patients was 29 years. Decreased vision (eight) was the most common presenting symptom. Ciliary body medulloepithelioma was the most common clinical diagnosis (six). Medulloepithelioma was the most common histopathological diagnosis (four). The duration of follow-up ranged from 0.5 to 67 months (median 11 months). Three eyes needed to be enucleated in the postoperative period (margin involvement two eyes, recurrence one eye). Postoperative complications among others included retinal detachment (three), vitreous hemorrhage (three), cataract (two), and suprachoroidal hemorrhage (two). To conclude, prognosis of this procedure continues to be guarded needing close postoperative follow-up.     

Our experience in the removal of intravitreal and subretinal cysticerci

Ocular cysticercosis is a rather infrequent entity even in developing countries. Several treatments have been proposed depending on the location of the organism within the eye. Three cases are described, emphasizing treatment of a subretinal cysticercus with sclerotomy instead of photocoagulation.     

Combined phacoemulsification, vitrectomy, foreign-body extraction, and intraocular lens implantation

PURPOSE: To assess the outcome of simultaneous phacoemulsification, pars plana vitrectomy, intraocular foreign-body extraction, and intraocular lens (IOL) implantation. SETTING: SSK Ankara Eye Hospital, Department of Vitreoretinal Surgery, Ankara, Turkey. METHODS: Seventeen patients with corneal perforation, intraocular foreign body, vitreous hemorrhage, and lens opacity had simultaneous clear corneal phacoemulsification, pars plana vitrectomy, intraocular foreign-body extraction, and IOL implantation. RESULTS: Postoperative complications included massive retinal fibrosis in 2 patients, retinal detachment in 1, and cilioretinal artery occlusion in 1. At a mean follow-up of 15.2 months, best corrected visual acuity improved in the remaining 13 eyes (76%). The IOL was stable in all cases. CONCLUSION: Combined phacoemulsification with IOL implantation and vitreoretinal surgery was safe in selected cases of penetrating ocular trauma resulting from an intraocular foreign body.     

Biomicroscopy of surface deposits resembling foreign-body giant cells on implanted intraocular lenses

Deposits resembling foreign-body giant cells, which can be seen on specular reflex slit-lamp examination, were studied in vivo with a wide-field specular microscope using a low-power dipping cone lens in three cases of posterior chamber lens implantation. The deposits seen as iris pigment on routine examination showed two types of cell-like figures: round, bipolar or ameboid small figures with long branching processes and round, oval, or bizarre large figures. The large cell type had the pigment particles at the central or paracentral area and vacuole-like structures adjacent to the pigment particles. The specular photomicrographic characteristics were similar to those of fibroblast-like cells and foreign-body giant cells, which had been shown on the surfaces of extracted implanted intraocular lenses by the lens implant cytology technique.     

Cause of intraocular lens removal

To determine the rates of and reasons for removal of intraocular lenses (IOLs) during the first 6 years of implant surgery at Halifax Infirmary Hospital, we reviewed the medical records of all patients who underwent primary cataract extraction with IOL implantation and subsequent removal of the IOL between 1980 and 1985. Among 2482 patients 21 cases of secondary explanation (0.8%) were identified. Of the 21 IOLs 20 were anterior chamber lenses and 1 was a posterior chamber lens. The most frequent causes of IOL removal were suspected bacterial endophthalmitis, excessive lens movement due to poor fit and traumatic dislocation of the lens.

Early versus late removal of retained intraocular foreign bodies.

PURPOSE: To compare early versus late removal of retained intraocular foreign bodies (IOFBs). METHODS: Sixty-two patients presenting with open-globe injuries due to lacerations by retained IOFBs were consecutively operated by the same surgeon between 1989 and 1997. Minimum follow-up was more than 3 months. In 43 patients, the IOFB was removed during the first 24 hours after the accident. In 19 patients, in whom the wound had been closed during a first operation, the IOFB was removed later than 24 hours after the accident. The study groups did not vary significantly in age, refractive error, type and size of IOFB, prevalence of traumatic cataract and peripheral or central corneal lacerations, or visual acuity on presentation. RESULTS: Endophthalmitis developed significantly more often in the late intervention group than in the early intervention group (3/19 [15.7%] versus 1/43 [2.3%]; P = 0.0467; chi-square test). Considering patients with retinal lesions due to the IOFB (n = 47), proliferative vitreoretinopathy occurred significantly more often in the late intervention group than in the early intervention group (6/13 [46.2%] versus 6/34 [17.6%]; P = 0.0449). CONCLUSIONS: Confirming previous reports, the results of the current study suggest that removing retained IOFBs within the first 24 hours after the injury may in some clinical situations reduce the risks of infectious endophthalmitis and proliferative vitreoretinopathy.     

玻璃体切割术摘除眼内异物的临床观察

目的:探讨玻璃体切割术治疗眼外伤眼内异物存留的方法、效果和并发症。方法:分析36例眼内异物玻璃体切割术的病例,采用常规睫状体平坦部三切口闭合式玻璃体切割,异物经睫状体平坦部用异物镊夹出。结果:异物取出率100%,术后视力:提高25例,不变4例,下降7例。结论:玻璃体切割术可以准确有效地取出各种异物,而且损伤小,能最大限度地恢复视功能。     

Posterior dislocation of an intraocular lens implant and its removal.

The cause of dislocation of an intraocular lens is a direct blow or jerk, and dislocation may complicate both iris-supported and capsule-supported lenses. In capsule-supported lenses the implant dislocates towards the anterior chamber but in iris-supported lenses the dislocation is posterior. A technique for removal of a posterity dislocated lens is described.     

玻璃体手术治疗眼内异物分析

目的：探讨眼内异物的玻璃体手术取出方法的优缺点。方法：35例（35只眼）眼内异物患者，伴严重眼内炎3只眼，外伤性白内障22只眼，玻璃体出血机化16只眼。经眼底和超声检查伴视网膜脱离12只眼。玻璃体部分后脱离5只眼。异物为铁、铜、不锈钢、玻璃、石块、矿砂等，大小自0．5mm-25mm，大部分伴屈光间质混浊，异物停留在玻璃体、视网膜或球壁，经玻璃体手术取出，再结合切除混浊晶状体、环扎、气液交换、注硅油等。结果：异物一次取出成功34只眼，占97．1％。手术后并发症主要有出血、高眼压、白内障和视网膜脱离等。术后视力下降6只眼，不变10只眼，好转19只眼。结论：玻璃体手术取异物能同时解除屈光间质混浊、眼内炎，治疗视网膜脱离，是一种较好的手术。但也有不少并发症，手术复杂，需仔细检查、设计周密，术中配合良好，才能达到取异物成功、并发症少的最理想后果。

Our experience with myopic implants. Initial optical results

28 patients with high myopia (over-10 dioptries) were implanted in anterior chamber with a myopic IOL. 3 months postoperatively the visual acuity without correction was equal to the preoperative acuity. With a light correction, especially of residual astigmatism, we noticed a gain of acuity of 0.2.     

Sixteen months'' experience with 140 posterior chamber intraocular lens implants.

Three main designs of posterior chamber lenses in 140 cases have been reviewed. The visual results are satisfactory; patient satisfaction is good; and postoperative complications are limited to anterior dislocation of the feet of the lens and the necessity to wash out cortical remnants from behind the prosthesis in a small percentage of cases. The posterior chamber prosthesis is free from some of the complications of other intraocular lenses and probably provides the most 'normal' looking eye of any pseudophakoi.
