The effect of the fourth-generation fluoroquinolones on corneal reepithelialization after penetrating keratoplasty

PURPOSE: To compare the effects of topical moxifloxacin and gatifloxacin on corneal reepithelialization after penetrating keratoplasty. METHODS: In this single-center, open-label, prospective study, 46 consecutive patients requiring penetrating keratoplasty were alternately assigned to receive either postoperative moxifloxacin 0.5% ophthalmic solution (n = 23; Vigamox) or gatifloxacin 0.3% ophthalmic solution (n = 23; Zymar). The primary outcome measure was the area of the epithelial defect measured by slit-lamp evaluation during the postoperative period. RESULTS: The mean area of the epithelial defect was similar in both treatment groups at baseline (P = 0.104), but it was significantly larger in the moxifloxacin group than in the gatifloxacin group at day 4 (23.9 mm2 versus 10.6 mm2, respectively; P < .001) and day 7 (3.8 mm2 versus 0.85 mm2, respectively; P = 0.03). At every follow-up visit after day 4, there were more eyes with complete reepithelialization of the corneal graft in the gatifloxacin group than in the moxifloxacin group (statistically significant at days 7 and 14). CONCLUSIONS: The results of this preliminary study suggest that the postoperative use of gatifloxacin in corneal transplant patients may allow the early stages of corneal graft reepithelialization to proceed more quickly than does treatment with moxifloxacin. These findings suggest that a larger, masked, randomized clinical study in a more homogeneous patient population is warranted to further investigate the relative effects of moxifloxacin and gatifloxacin on postoperative corneal wound healing.

Low-dose intraoperative mitomycin-C versus conjunctival autograft in primary pterygium surgery: long term follow-up

PURPOSE: To evaluate and compare the long term safety and efficacy of low-dose intraoperative application of mitomycin-C (0.02%) with conjunctival autograft in primary pterygium surgery. PATIENTS AND METHODS: Of 37 consecutive patients 41 eyes with primary pterygium underwent pterygium excision with either intraoperative mitomycin-C (0.02%) (Group I) or conjunctival autografts (Group II) at random. Mitomycin-C (0.2 mg/mL) was applied for 2.5 minutes on the scleral bed under the conjunctiva. Conjunctival autograft was obtained from upper temporal limbus and secured with 10-0 monofilament nylon. The follow-up period ranged from 14 to 54 months (mean 36 months) for mitomycin-C group and 13 to 58 months (mean 38 months) for conjunctival autograft group. RESULTS: Twenty-one eyes underwent pterygium excision with intraoperative mitomycin-C (0.02%) application (Group I) and 20 eyes were treated using conjunctival autograft (Group II). The mean size of the pterygium was 3.80 mm (range 2.6 to 4.8 mm) in the mitomycin-C group and 3.60 mm (range 2.5 to 4.5 mm) in the conjunctival autograft group. Two (9.52%) eyes treated with intraoperative mitomycin-C had delayed epithelial healing of corneoscleral wound and one (4.76%) eye developed pyogenic granuloma. Three (14.3%) of the 21 eyes in Group I and one (5%) of 20 eyes in Group II had recurrence of pterygium (P = 0.3174). All recurrences occurred in patients below 40 years of age (P = 0.0384). CONCLUSION: We conclude that conjunctival autograft and intraoperative mitomycin-C are both equally effective adjuncts to primary pterygium surgery on long term follow-up. However, future prospective studies with larger numbers of subjects may be carried out to find out the optimum concentration and duration of intraoperative mitomycin-C application.

Results of pterygium excision adjunct with conjunctival autograft transplantation for primary pterygium by ophthalmology trainees

To evaluate the results of pterygium excision with conjunctival autograft transplantation for primary pterygium performed by trainee ophthalmologists. Design Prospective interventional case series. Setting A tertiary eye care center in northern Thailand. Participants Patients with primary pterygium recruited from July 2011 to August 2012. Intervention In all cases, the affected eye underwent pterygium excision followed by a superior conjunctival autograft carried out by trainee ophthalmologists. Main outcome measure The recurrence of pterygium and other post-operative complications. Results Sixty-two eyes from 54 patients were studied. There were 36 females (66.7 %) and 18 males (33.3 %). The mean age of the patients was 54.5 (±9.8) years with the mean corneal invasion measured at 3.3(±0.8) mm. Pterygium morphologies of Grade 1, Grade 2, and Grade 3 were 33.9, 48.4, and 17.7 %, respectively, with the mean follow-up time of 17.3 (±7.9) months. Pterygium recurred in the cornea of six eyes (9.7 %). All recurrences occurred within 6-month post-operation. Other post-operative complications included conjunctival recurrence (4.8 %), graft retraction (3.2 %), conjunctival cyst (3.2 %), and increased intraocular pressure (1.6 %). The recurrence of pterygium was not associated with the patient age (p = 0.72), occupation (p = 0.23), sun exposure time (p = 0.18), pterygium duration (p = 0.22), pterygium size (p = 0.67), or pterygium morphology (p = 0.85). Conclusion The recurrence rate and post-operative complications of pterygium excision with conjunctival autograft performed by trainee ophthalmologists were within acceptable limits. All recurrence occurred within 6 months after surgery.     

Comparison of the effects of fourth-generation fluoroquinolones on corneal re-epithelialization in rabbit eyes

BACKGROUND: Gatifloxacin and moxifloxacin ophthalmic solutions are frequently prescribed for antimicrobial prophylaxis following cataract and corneal refractive surgeries, although the use of topical antibiotics is likely to interfere with wound healing in the immediate postoperative period. A potential factor that may influence rates of wound healing or corneal re-epithelialization is how the solutions are preserved. Gatifloxacin is preserved with 0.005% benzalkonium chloride, whereas moxifloxacin is unpreserved. The purpose of this study was to evaluate the effects of commercially prepared topical gatifloxacin and moxifloxacin on corneal re-epithelialization in rabbit eyes. METHODS: In this randomized, prospective, controlled study, 17 New Zealand white rabbits underwent bilateral corneal de-epithelialization procedures using 20% alcohol contained within a 6 mm trephine. Postoperatively, eyes were randomly assigned to receive either gatifloxacin 0.3%, moxifloxacin 0.5%, or balanced salt solution (BSS) four times daily. Each 6 hours during the first 2 days, and every 12 hours thereafter slit-lamp measurements and corneal photography were performed, enabling de-epithelialized surface areas to be calculated via EPCO 2000 computer analysis. RESULTS: Gatifloxacin (n = 12) and moxifloxacin (n = 13) treated eyes had a statistically significant (p = 0.036) delay in epithelial healing relative to controls (BSS, n = 8). Healing rates of gatifloxacin and moxifloxacin treated eyes were not significantly different (p = 0.545). CONCLUSIONS: We found no significant difference in re-epithelialization rates following topical application of gatifloxacin 0.3% and moxifloxacin 0.5%. Both antibiotic solutions delayed healing compared to BSS. Our analysis suggests that there was no apparent added epithelial toxicity due to the presence of BAK in the gatifloxacin preparation.     

Antibiotic susceptibility of preoperative normal conjunctival bacteria

PURPOSE: To determine the antibiotic susceptibility of preoperative conjunctival bacterial flora. DESIGN: In vitro study. METHODS: Antibiotic susceptibility of conjunctival bacterial strains isolated from 164 patients undergoing intraocular surgery was determined using the Kirby-Bauer disk-diffusion technique. RESULTS: Among the 162 bacteria isolated, 124 (76%) were coagulase-negative staphylococci (CNS), with 2% resistant to gatifloxacin and moxifloxacin, and none were resistant to vancomycin or minocycline. Other bacteria isolated were 19 Staphylococcus aureus (S. aureus), 8 Streptococcus Group D, and 11 gram-negative rods. Most S. aureus (>85%) were susceptible to all antibiotics except for the penicillin and macrolide groups. No streptococci were resistant to gatifloxacin, levofloxacin, moxifloxacin, mezlocillin, imipenem, or vancomycin. None of the gram-negative rods were resistant to the fluoroquinolones. Approximately one half of all bacteria were resistant to erythromycin. One in three patients harbored multi-resistant bacteria (resistant to > or = five antibiotics). CONCLUSIONS: Newer-generation fluoroquinolones provide excellent broad-spectrum coverage against conjunctival bacterial flora.

Sutureless amniotic membrane transplantation combined with narrow-strip conjunctival autograft for pterygium

To study the efficacy and safety of sutureless amniotic membrane transplantation combined with narrow-strip conjunctival autograft and to investigate the clinical outcomes. Thirty eyes of 30 patients with primary pterygia were treated in this institutional study with excision followed by sutureless amniotic membrane transplantation combined with narrow-strip conjunctival autograft using fibrin glue tissue adhesive. The main outcome measures were the operating time for ocular surface reconstruction, the size of the pterygium and of the conjunctival autograft, postoperative complications, subjective complaints, and recurrences. The mean pterygium size was 3.12 ± 0.92 mm and the mean operating time was 4.58 ± 1.10 min. Twenty-nine patients (96.7%) had no complaints after first postoperative week. Twenty-eight (93.3%) patients had no recurrences after 1 year follow-up. The sutureless amniotic membrane transplantation combined with narrow-strip conjunctival autograft is an effective procedure with low rate of recurrence. This technique can be considered as a preferred grafting procedure for primary pterygium but further randomized controlled studies including larger populations are needed.

结果：结膜植片愈合时间6.03±2.76d,羊膜溶解吸收时间14.26±3.64d,角膜创面修复时间5.42±1.58d。术后3mo,胬肉切除后裸露巩膜面新生结膜及结膜植片愈合良好,无明显胬肉术后并发症。术后1a,再度复发2例,复发率8%,治愈率92%。

结论：对于复发性翼状胬肉,因传统自体角膜缘干细胞移植已经创伤部分角膜缘及眼表结膜瘢痕,单纯结膜移植,或单纯羊膜移植,术后胬肉复发率偏高,本方法取胬肉上结膜反向移植,避免大面积创伤眼表,取材容易,而且良好控制术后翼状胬肉复发问题,不失为一种解决复发性翼状胬肉的良好选择。
