翼状胬肉术后角巩膜溶解6眼

0引言翼状胬肉是眼科常见病和多发病,治疗以手术为主。但是单纯胬肉切除术后复发率高达20%~70%[1]。近年来国内外眼科学者为了预防翼状胬肉术后复发,不断改进手术方式,同时术中术后联合应用抗代谢药物等方法极大地降低了手术后复发率,但同时也出现了新的术后并发症的发生,有的并发症可严重影响视功能,甚至丧失眼球[2]。现将我院近年来翼状胬肉切除联合丝裂霉素C(MMC)术后角巩膜溶解6眼,报告如下。1临床资料总结我院2003-12/2008-08门诊及住院翼状胬肉切除联合MMC术后角巩膜溶解6眼,其中女5眼,男1眼,年龄50~73岁,2眼为复发性胬肉。显微镜下行胬肉切除术。切除胬肉体部,保留胬肉头部不     

An overview of management of pterygium in Nigeria

To review the management of pterygiumin Nigeria. ·METHODS: The medical records of patients who had pterygium excisions over a four year period (January 1999-December 2002) were reviewed. These patients were seen at University of Nigeria Teaching Hospital and Ebrans Clinic both in Enugu, Nigeria. The analysis of patients' bio-data, clinical presentation, surgical management and post-operative complications were carried out using EPI-INFO version 6.1. Three surgical techniques were employed: bare sclera procedure only (60 eyes); bare sclera with adjuvant 5-fluorouracil (42 eyes) and bare sclera with mitomycin-C, MMC, (22 eyes). · RESULTS: One hundred and twenty-four eyes of 72 patients had pterygium excisions and were followed up for a least one year post-operatively. There were 41 males (56.9%) and 31 females (43.1%) giving a male to female ratio of 1:0.8. The mean age was 42.8 years while the range was 20-69 years. Recurrence was highest in stage III (55.6%) and lowest in stage I (22.2%). Concerning the 3 surgical techniques, the recurrence rates were 65.0%, 52% and 13.6%respectively. ·CONCLUSION: In the management of pterygiumin a developing country, early excision with use of intraoperative MMC is advocated. It is safe, affordable, technically easier and less invasive.     

Intraoperative mitomycin C versus autologous conjunctival autograft in surgery of primary pterygium with four‐year follow‐up

Purpose: To compare the 4‐year outcome of primary pterygium excision using intraoperative mitomycin C (MMC) with suturing a free conjunctival autograft (CA). Methods: A total of 115 eyes with nasal primary pterygium of 115 patients were included in the study. After randomization into two groups, the eyes were operated on by a single surgeon (GK). After excision of the pterygium, 56 eyes received 0.04% MMC intraoperatively on the bare sclera for 3 min and 59 eyes received a free CA sutured using 7‐0 Vicryl. Postoperative follow‐up was 4 years. Main outcome measures were recurrences, re‐operations, surgery time, complications, visual acuity and astigmatism. Statistical evaluation was performed with the chi‐squared test. Results: The recurrence rate was 38% in the MMC group and 15% in the CA group (p < 0.05). The re‐operation rate of the recurrences was 53% in the MMC group and 29% in the CA group. Average surgery time was 13 minutes (range: 6–22 min) in the MMC group and 26 min (range: 18–32 min) in the CA group (p < 0.01). There was no significant change in best‐corrected visual acuity and astigmatism. One major complication occurred in each group. The most frequently observed complication was delayed epithelial healing (40%) and mild scleral thinning (20%) in the MMC group and suture‐related inflammation in the CA group (10%). Conclusion: Pterygium surgery including free autologous conjunctival grafting is associated with fewer recurrences, re‐operations and complications than using the bare sclera technique together with single‐dose intraoperative MMC.     

Low-dose intraoperative mitomycin C as chemoadjuvant for pterygium surgery

PURPOSE: To evaluate the efficacy and safety of low-dose intraoperative mitomycin C (MMC) during bare sclera procedure and to compare the rates of pterygium recurrence between recurrent pterygium patients treated with adjuvant MMC and those reconstructed with a conjunctival autograft. METHODS: We studied the recurrence of pterygium, 12-month pterygium-free survival rates, final appearance, and postoperative complications in 96 eyes of 92 patients who received either intraoperative 0.02% MMC for 30 seconds or conjunctival autografting after pterygium excision. Patients were divided into three groups: group 1 included 38 eyes with primary pterygium undergone intraoperative MMC; group 2, 26 eyes with recurrent pterygium treated with intraoperative MMC; and group 3, 32 eyes with recurrent pterygium treated with pterygium excision and conjunctival autografting. RESULTS: Pterygium recurred in 3 (7.9%) of 38 eyes in group 1, 5 (19.2%) of 26 eyes in group 2, and 2 (6.3%) of 32 eyes in group 3. Despite the higher recurrence rate in group 2 compared with that of group 3, the difference between the two was not statistically significant (p = 0.22). The cumulative probabilities of success were 91.6+/-4.6%, 80.8+/-7.7%, and 92.3+/-5.4% at 12 months for groups 1, 2, and 3, respectively. Final appearance of the pterygium excision area was satisfactory in nearly two-thirds of the MMC-treated patients, 71.1% and 65.4% for groups I and 2, compared to 75.1% of patients who had undergone conjunctival autografting. No patients experienced severe complications during a mean postoperative follow-up of 27.3+/-4.1 months, 29.9+/-3.9 months, and 40.9+/-19.1 months for groups 1, 2, and 3, respectively. CONCLUSIONS: A single intraoperative application of 0.02% MMC for 30 seconds after pterygium excision is associated with minimal complication and effectively reduces the recurrence rates after excision of primary or recurrent pterygium. In comparison with conjunctival autografting, low-dose application of MMC after bare sclera procedure is less efficacious in preventing recurrence of pterygium, but simpler and produces a similar proportion of patients with satisfactory final appearance.     

Mitomycin C for pterygium: long term evaluation

AIM: To evaluate long term complications after pterygium excision with mitomycin C (MMC) application. DESIGN: Prospective non-comparative interventional case series. PARTICIPANTS: Ninety nine patients who underwent pterygium surgery and participated in a controlled study for efficacy of MMC for pterygium surgery between 1989 and 1994. METHODS: Patients who were located and agreed to come for examination underwent a complete eye examination. The bare sclera area, in particular, was examined for possible complications. The main outcome measures were anatomical findings in area of MMC application. RESULTS: Forty three eyes of 43 patients were examined. Sixty three per cent of patients had pterygium surgery with intraoperative application of 0.02% MMC for 5 minutes and 37% of patients received MMC 1% or 2% drops four times daily for 2 weeks postoperatively. In three patients, pterygium recurred within 18 months. The only complication was mild conjunctival avascularity in areas of pterygium excision in 30% of patients. CONCLUSION: Long term evaluation revealed that the use of MMC in pterygium surgery is safe, but for a strict selection of patients, controlled use of MMC and long term follow up are required.

Comparison of single-drop mitomycin C regime with other mitomycin C regimes in pterygium surgery

PURPOSE: To evaluate the safety and efficacy of single-drop instillation of mitomycin C (MMC) in pterygium surgery and to compare the results with both postoperative and intraoperative application of MMC. METHODS: Eighty eyes of 72 patients with pterygium were randomised into 4 equal groups: group 1--control--bare scleral excision (BSE); group 2--BSE with single-drop instillation of mitomycin C (MMC) 0.02% at the end of the surgery; group 3--BSE with postoperative MMC 0.02% drops twice a day for 5 days; and group 4--BSE with intraoperative MMC 0.02%. RESULTS: The recurrence of pterygium was observed in 14 (70%), 4 (20%), 4 (20%) and 3 (15%) eyes of group 1, 2, 3, and 4 respectively. The recurrence rate after BSE with single drop MMC regime (group 2) was significantly lower than group 1 recurrence (P=0.001) and was statistically comparable to that of group 3 and 4. Scleral defects in the bare area occurred in 4 (20%), 16 (80%) and 16 (80%) eyes of group 2, 3, and 4 respectively. The incidence of scleral defects was significantly lower in group 2 compared to group 3 (P=0.0001) and group 4 (P=0.0001). Compared to group 1 and 2, a significant delay in wound epithelialisation occurred in group 3 (P=0.003) and 4 (P=0.004). An ischaemic area in the bare sclera developed in 8 (40%) and 6 (30%) eyes of group 3 and 4 respectively, while ischaemic area did not develop in group 1 and 2. CONCLUSION: Single-drop instillation of 0.02% mitomycin C following pterygium excision appears both safe and efficacious.

Amniotic membrane grafting in the surgical management of primary pterygium

BACKGROUND: To evaluate the efficacy of amniotic membrane transplantation in primary pterygium surgery. METHODS: Patients presenting to the outpatient clinic of the Royal Victorian Eye and Ear Hospital with primary pterygium requiring surgical management were included in this study. The pterygia were excised to bare sclera and the conjunctival defects were closed with amniotic membrane grafts. The primary outcome was pterygium recurrence. RESULTS: Twenty-eight pterygia of 26 patients were included. Twenty-three patients (88%, 25 eyes) completed 12 months follow up. By 12 months postoperatively 16 of these eyes (64%) had developed corneal recurrence and a further two had developed a limbal recurrence (9%). Five required repeat surgery during the 12 month follow-up period. No association was found between pterygium recurrence and pterygium size (P = 0.33), amniotic membrane graft dimension (P = 0.12), patient age (P = 0.53) or patient sex (P = 0.63). CONCLUSION: Amniotic membrane grafting for primary pterygium was associated with an unacceptably high recurrence rate in this population.     

Role of mitomycin C in pterygium surgery.

Mitomycin C in the form of eye drops in a concentration of 0.4 mg/ml (0.04%) was used as adjunctive treatment for primary and recurrent pterygium after surgical excision. The study was concurrent in nature and consisted of 32 pterygia in 30 patients and was done over a period of 36 months. The object was to observe the effect of mitomycin C drops on pterygium recurrence after surgical excision. Fifteen eyes of 15 patients were treated with 'bare sclera technique' for pterygium excision. Nine patients showed recurrence occurring within first 6 months of surgery. On the other hand 17 eyes of 15 patients after bare sclera pterygium excision received mitomycin 0.4 mg/ml (0.04%) eye drops four times a day for 2 weeks from first postoperative day. There was no recurrence of pterygium in this group. Follow up time for these cases ranged from 13-19 months.
