RESUMEN
BACKGROUND AND OBJECTIVE: The complications of 25-gauge transconjunctival sutureless vitrectomy based on the surgical indications were reviewed. PATIENTS AND METHODS: Thirty-eight patients underwent 25-gauge transconjunctival sutureless vitrectomy. Indications for vitrectomy, preoperative and postoperative best-corrected visual acuity, preoperative and postoperative intraocular pressure, and any intraoperative or postoperative complications were recorded. RESULTS: Complications included the need to suture a leaking sclerotomy intraoperatively in four eyes (9%), all of which involved oil removal; postoperative hypotony with choroidals in two eyes (5%); mild progression of nuclear sclerotic cataract in one eye (2% of all eyes, 4% of phakic eyes); the need to switch to 20-gauge pars plana vitrectomy in one eye (2%); corneal abrasion in one eye (2%); and retinal detachment in one eye (2%). Sclerotomy leakage and hyopotony with choroidals were only encountered in cases involving previously vitrectomized eyes, whereas none of the eyes without previous vitrectomy had leakage-related complications. CONCLUSIONS: Previously vitrectomized eyes have a higher incidence of complications related to postoperative leakage, possibly due to the lack of plugging effect of peripheral vitreous on the unsutured sclerotomy. One should consider suturing any leaking sclerotomy at the conclusion of surgery involving previously vitrectomized eyes.

PURPOSE: A 64-year-old woman presenting with the complaint of 'white stuff' in her left eye one day after intravitreal triamcinolone injection for chronic pseudophakic cystoid macular edema after cataract extraction and anterior chamber intraocular lens implant is presented. METHODS: Differential diagnosis included post-injection endophthalmitis versus 'steroid hypopyon.' RESULTS: The patient was observed closely and the hypopyon cleared in four days. Three weeks after the injection, her visual acuity had improved from 20/200 to 20/70 with complete resolution of the macular edema. CONCLUSION: Patients having no capsular barrier presenting with hypopyon one day after IVTA may be observed closely for a few days for resolution of hypopyon prior to being treated as endophthalmitis.

PURPOSE: To assess the prevalence and location of Lisch nodules among patients with neurofibromatosis type 1. PATIENTS AND METHODS: This was a prospective observational case series in which 369 consecutive patients from a neurofibromatosis clinic participated. Predetermined inclusion and exclusion criteria were applied to these participants. The presence of Lisch nodules was determined by one of the authors (SMC). The percentage of patients with neurofibromatosis type 1 with Lisch nodules was calculated. Lisch nodules were characterized as being distributed superiorly, inferiorly, or equally in each eye. The percentage of eyes in each group was ascertained. RESULTS: Among patients of all ages with neurofibromatosis type 1, 63.2% had Lisch nodules, whereas 92% of postpubertal patients had Lisch nodules. Among eyes with Lisch nodules, 80% had an inferior distribution. CONCLUSIONS: This study corroborated previously reported data regarding the prevalence of Lisch nodules in patients with neurofibromatosis type 1 and found that Lisch nodules were predominantly located inferiorly on the iris. The authors propose that exposure to sunlight may be the mechanism for this distribution of hamartomatous nodules.
