Design: Retrospective,noncomparative,multicenter,interventional small case series. Participants: Four patients with linear BCC in the periocular region. Intervention: All patients underwent margin-controlled excision,3 utilizing Mohs’ micrographic surgery and 1 using frozen section. Main Outcome Measures: Age,gender,location,preoperative tumor size,histological growth pattern,presence of perineural invasion,number of Mohs’ levels used to obtain histologic clearance,postoperative defect size,and recurrence. Results: In all 4 cases,the site of occurrence was in the lower eyelid and cheek. Histology revealed pigmented nodular BCC with an infiltrative component in 2 cases and nodular BCC in the remaining 2 cases. No perineural invasion was noted in any of the cases. Two Mohs’ levels were required for complete excision in 3 patients. Conclusions: Linear BCC is a distinct clinical entity. Presence of the tumor along relaxing skin tension lines,increase in subclinical extension,and aggressive tumor behavior are reported observations. Because of these observations,it is suggested that margin-controlled excision should be considered for linear BCC.展开更多

Methods: Nine patients with traumatic iris defects, congenital aniridia or iris coloboma, and surgical or o ptical iridectomies were included in a noncomparative case series. Cataract surg ery with intraocular lens and prosthetic iris implantation was performed in 10 e yes. The visual acuity, subjective degree of glare disability, postoperative ana tomic results, and intraoperative and postoperative complications were evaluated . Results: The mean follow-up was 17.75 months (range 4-48 months). Best-corr ected 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 co mplaining of glare preoperatively. All eyes achieved the desired anatomic result . Intraoperative complications included one anterior capsular tear. Postoperativ e complications included a short period of mild postoperative anterior uveitis in four eyes. Secondary glaucoma was absent. Conclusion: In patients w ith iris deficiency, implantation of prosthetic iris device, and intraocular len s implant following cataract surgery appears to be safe and effective in reducin g glare disability and improving visual outcomes.展开更多
