1/10. Management of post-traumatic aniridia with retinal detachment.PURPOSE: To reconstruct the anatomic and functional impairment in patients with post-traumatic aniridia, aphakia, and retinal detachment. methods: Four patients with unilateral aniridia and aphakia as well as retinal detachment as results of severe eye injuries underwent scleral buckling, vitrectomy, membrane peeling, endolaser photocoagulation, silicone oil or gas temponade, combined with iris diaphragm-IOL implantation. RESULTS: All four patients achieved successfully anatomic and functional reconstruction after surgery. During five to 22 months postoperative follow-up, all retinas remained attached. The final visual acuity increased from finger counting to 0.1-0.3. CONCLUSIONS: The combination of vitreoretinal surgery and iris diaphrgm-IOL implantation is an effective method for post-traumatic aniridia, aphakia and traumatic retinal detachment. It could ameliorate photophobia and improve the biocular vision. Furthermore, artificial iris diaphragm implantation could prevent silicone oil-endothelia contact and salvage silicone keratopathy.- - - - - - - - - - ranking = 1keywords = aphakia (Clic here for more details about this article) |
2/10. Management of traumatic aniridia and aphakia with an iris reconstruction implant.We describe the clinical features and management of a 36-year-old man with aniridia and aphakia following blunt ocular trauma. Examination showed partial aniridia and aphakia. We discuss the various options available in the management of this patient and describe the surgical technique involved in the implantation of an iris reconstruction implant.- - - - - - - - - - ranking = 2keywords = aphakia (Clic here for more details about this article) |
3/10. Traumatic lenticele.A 55-year-old woman presented with sudden diminution of vision in her left eye following trauma with her own finger. Examination revealed a firm subconjunctival swelling superiorly with aphakia and hypotony. Lens spike was absent on B-scan. Ultrasonic biomicroscopy showed thickened conjunctiva, a subconjunctival mass lesion with an underlying uveoscleral discontinuity. A surgical repair was performed with successful restoration of globe integrity. This case demonstrates that ultrasonic biomicroscopy may reveal the site and the extent of occult scleral rupture and help in precise surgical planning.- - - - - - - - - - ranking = 0.33333333333333keywords = aphakia (Clic here for more details about this article) |
4/10. Use of the artificial iris implant in patients with aniridia.BACKGROUND: aniridia (or partial aniridia) often occurs as a result of a penetrating ocular trauma. This condition may cause symptoms including glare, light sensitivity, reduced vision, and asymmetric appearance. Options for these patients include specialty contact lenses, corneal tattooing, and artificial iris implants. This article details six patients who experienced penetrating trauma with significant iris tissue loss and who chose to have an artificial iris implant. case reports: Six patients with traumatic aniridia were enrolled in a single-site, single-surgeon study. They were followed for one year postoperatively. All six were complex cases that had multiple eye problems, such as aphakia, corneal scarring, corneal graft rejection, and retinal detachment. All participants were male. All patients experienced decrease in glare and light sensitivity following artificial iris implant surgery. Two experienced improved best-corrected vision (BCVA). All six patients felt the cosmetic appearance of their affected eye improved. CONCLUSIONS: The artificial iris device provides an effective means of treating traumatic aniridia. Optometrists often work with patients who have experienced a penetrating ocular trauma, with complete or partial aniridia as a complication. In cases in which nonsurgical means are not effective in returning the patient to comfort and productivity, an artificial iris implant should be considered.- - - - - - - - - - ranking = 0.33333333333333keywords = aphakia (Clic here for more details about this article) |
5/10. epikeratophakia after ocular trauma.Five patients with long-standing monocular traumatic aphakia and contact lens intolerance underwent epikeratophakia. This procedure was chosen to rehabilitate the visual function in those eyes that exhibited distorted anterior segment anatomy after trauma. Three of the patients had corneal scars associated with their old perforation wounds, and all of them had undergone an intracapsular cataract extraction soon after their original injuries. Best-corrected visual acuity was 20/50 or better in all cases before surgery. Postoperative best-corrected visual acuity improved to within two lines of the best-corrected preoperative visual acuity, after a minimum follow-up period of six months. No intraoperative complications were noted. One cornea developed late-onset partial scarring of the interface in the area of the original scar, but the process arrested spontaneously.- - - - - - - - - - ranking = 0.33333333333333keywords = aphakia (Clic here for more details about this article) |
6/10. epikeratophakia following rotational autokeratoplasty in a child.A 3-year-old child with posttraumatic aphakia and a corneal scar was treated with a rotational penetrating ipsilateral autokeratoplasty followed by epikeratophakia 2 months later. His final best corrected visual acuity was 20/30, with 1.37D of corneal astigmatism. There were no significant operative or postoperative complications.- - - - - - - - - - ranking = 0.33333333333333keywords = aphakia (Clic here for more details about this article) |
7/10. epikeratophakia in children with traumatic cataracts.epikeratophakia provides a permanent optical correction for aphakia in children with congenital or traumatic cataracts; suturing the epikeratophakia graft onto the cornea eliminates the problems of contact lens or spectacle non-compliance in these young and generally uncooperative patients and provides tectonic support to scarred and irregular corneas. Eighteen children under the age of six years underwent epikeratophakia for the correction of aphakia after the removal of trauma-induced cataracts. Graft success rate was 88%; the average change in keratometry in the patients with successful grafts was 14.82 /- 2.0 diopters. In the 13 patients eligible for visual acuity tabulation, preoperative acuities ranged from light perception to 20/200, and postoperative acuities ranged from hand motions to 20/30. Ten (77%) had acuities of 20/80 or better. Poor results in three patients with less than 20/200 acuities were likely the results of non-compliance with amblyopia therapy. Present work indicates that in cases of traumatic cataract, the epikeratophakia procedure facilitates amblyopia therapy and decreases the astigmatism in scarred and irregular corneas.- - - - - - - - - - ranking = 0.66666666666667keywords = aphakia (Clic here for more details about this article) |
8/10. vitrectomy in complicated retinal detachments.In this paper complicated traction retinal detachments are discussed in relation to aetiology, techniques of treatment and results of treatment. Complicated traction detachments are caused by pathological vitreous membranes or bands and epiretinal membranes. These membranes are found in the following groups of eyes: aphakia were vitreous loss, penetrating trauma, chronic vitreous inflammation and failed retinal detachments. patients with extramacular traction detachments are not necessarily treated. patients with diabetic traction retinal detachment are not included in this series. Of 150 consecutive pars plana vitrectomy operations--34 operations were for complicated traction retinal detachments.- - - - - - - - - - ranking = 0.33333333333333keywords = aphakia (Clic here for more details about this article) |
9/10. epikeratophakia to correct traumatic aphakia after penetrating keratoplasty.A 19-year-old man with keratoconus sustained ocular trauma and became aphakic in his operated left eye 2 months after penetrating keratoplasty. Original corneal wound repair was performed without intraocular lens implantation. Attempts to correct his aphakia with a contact lens failed when the patient became intolerant to its use. As an alternative, the patient had elective epikeratophakia. A standard 8.5 mm lenticule was placed over existing corneal graft. This operation resulted in 12.25 diopters of correction and a best corrected visual acuity of 20/25 at 30 months postoperatively. There was no sign of abnormalities at the host cornea or the transplanted lenticule. This case indicates that epikeratophakia may be successfully performed over existing corneal grafts.- - - - - - - - - - ranking = 1.6666666666667keywords = aphakia (Clic here for more details about this article) |
10/10. Ocular perforation in utero.Midtrimester amniocentesis has rarely been reported to cause ocular damage. Findings in the literature include corneal perforation, a vascularized corneal leukoma, a non pigmented epithelial cyst of the anterior chamber, eyelid coloboma, microphthalmos, retinal hole, axial myopia and retinal detachment. We describe the case of a paralimbal scleral perforation with iris prolapse, distortion of the pupil, aphakia due to resorption of the lens and a chorioretinal scar possibly caused by an amniocentesis needle.- - - - - - - - - - ranking = 0.33333333333333keywords = aphakia (Clic here for more details about this article) |
