Successful treatment of verruca plana with NB‐UVB: A case report

Verruca plana is a kind of benign proliferative skin disease that generally occurs in exposed parts, but the treatment of warts poses a therapeutic challenge for physicians, as there is no method, among numerous approaches, that has been proven effective for completely curing this disease. We report a case of verruca plana cured by narrow‐band ultraviolet B (NB‐UVB), which provides a new treatment of verruca plana.

Evaluation of limbal and pars plana silicone oil removal in aphakic eyes

Purpose: To compare limbal and pars plana silicone oil removal (SOR) in aphakic eyes and to evaluate the acute effect of silicone oil flow to the corneal endothelium. Methods: Sixteen aphakic patients with silicone oil endotamponade requiring SOR were recruited for this prospective study and randomly scheduled for limbal or pars plana SOR. The central corneal thickness (CCT), visual acuity (VA) and intraocular pressure were measured preoperatively, on the first postoperative day and 4 months after surgery. Endothelial cell density (ECD) was measured preoperatively and at the end of follow‐up. The in vitro study was performed on ten enucleated porcine eyes. Corneoscleral discs were prepared and fixed on artificial anterior chamber followed by 2.5‐mm limbal incision and 5‐ml silicone oil injection in six cases and 5 ml balanced salt solution (BSS) in four cases. Results: The ECD decreased by 239.2 ± 86.7 (13.9%) and 86.7 ± 22.4 cells/mm² (5%) after limbal (n = 8) and pars plana SOR (n = 8), respectively (p < 0.001 for both). The difference between the groups was significant (p < 0.001). A significant increase in CCT and corresponding decrease in VA was noted on the first postoperative day using both procedures. At the end of follow‐up, the CCT and VA were comparable to initial values. Postoperative hypotony (≤6 mmHg) was observed more frequently after limbal SOR. In the experiment, lamellar abrasions of corneal endothelium were observed after silicone oil injection, whereas no changes were observed after BSS injection. Conclusion: Limbal SOR causes more considerable damage to the corneal endothelium than the pars plana approach because of mechanical abrasion.     

眼外伤晶体玻璃体切除术后Ⅱ期悬吊人工晶体植入术

目的:总结眼外伤行晶体玻璃体切除术后Ⅱ期悬吊人工晶体植入术的方法和疗效。方法:选择眼外伤后行晶体玻璃体切除术后的患者21例(21眼),均具有矫正视力>0.2、眼压稳定、眼底情况良好之条件,于3~6个月后行Ⅱ期悬吊人工晶体植入术。结果:随访1~6个月,平均4.5个月。矫正视力>0.5者6眼,0.3~0.5者10眼,0.1~0.2者4眼,<0.1者1眼。0.3及以上视力者16眼(80%)。术后裸眼视力比术前明显提高,矫正视力差异不大。结论:对于眼外伤行晶体玻璃体切除术后的患者,待眼部情况稳定3~6个月后行Ⅱ期悬吊人工晶体植入术是提高视力的理想方法,但要求术者需要具备一定的眼前后节手术经验,选择合适的病例。     

玻璃体切除联合硅油填充术治疗急性化脓性眼内炎

目的观察玻璃体切除联合硅油填充术治疗无视网膜脱离的严重急性化脓性眼内炎的疗效。方法回顾性分析15例行玻璃体切除联合硅油填充术的不伴有视网膜脱离的严重急性化脓性眼内炎的病例资料，观察术后的视功能、感染控制及再次手术情况。结果随访3～18月，15眼感染全部控制，1眼在硅油取出后发生视网膜脱离，其余14眼视网膜保持在位无需再次手术。与术前相比，13眼视力提高，1眼视力不变，1眼眼球萎缩。结论玻璃体切除联合硅油填充术能有效稳定视网膜功能，控制炎症，减少再次手术创伤。     

睫状体平坦部滤过术治疗难治性青光眼的临床研究

目的 探讨睫状体平坦部滤过术治疗难治性青光眼的可行性、有效性与安全性。方法 对经过药物、激光或手术治疗仍眼压失控的难治性青光眼13例13只眼，采用唐由之研究员设计发明的“睫状体平坦部滤过术”进行手术，观察手术前后视力、眼压等指标变化。结果 对接受睫状体平坦部滤过术治疗的13例13只眼，经过最长9个月的观察随访，眼压均得到了较满意的控制，视力稳定或提高，术中及术后未出现严重并发症。结论 初步临床观察表明，睫状体平坦部滤过术是治疗难治性青光眼的一种安全可行、有效的方法，值得进一步研究。

25-gauge, sutureless vitrectomy and standard 20-gauge pars plana vitrectomy in idiopathic epiretinal membrane surgery: a comparative pilot study

Background The aim of the study was to evaluate the safety and functional outcome of a small incision, sutureless vitrectomy in the treatment of idiopathic epiretinal membranes (ERM) compared with a standard 20-gauge vitrectomy system.Methods Forty-six consecutive patients with idiopathic ERM were recruited for this study and prospectively evaluated. In group 1 (n=26) we used a transconjunctival sutureless 25-gauge vitrectomy system (TSV), patients in group 2 (n=20) were operated on using a standard 20-gauge vitrectomy system. The ERM was removed and the internal limiting membrane (ILM) was peeled in all eyes. Surgery-related complications, operating time, intraoperative balanced salt solution (BSS) consumption, postoperative discomfort, postoperative intraocular inflammation, lens opacification, and long-term visual outcome are reported and compared.Results No surgery-related complications were observed in either group. Operating time was shorter in group 1 compared with group 2 (mean 15.6 and 29.6 min respectively). Intraoperative amount of BSS consumption was less in group 1 (mean 28 ml in group 1 and 42 ml in group 2). Postoperative discomfort and intraocular inflammation were significantly reduced in the 25-gauge group. In the 20-gauge group cataract formation requiring surgery was observed in two eyes. Visual acuity improved significantly in both groups. The 25-gauge group improved on average by more lines of vision and the improvement in vision was more rapid.Conclusion The TSV system is a safe and efficient surgical technique for ERM surgery. Operating time is significantly reduced, minimizing surgery-induced trauma, and reducing postoperative intraocular inflammation and the patients’ discomfort. The incidence of cataract formation may be less using TSV. Postoperative recovery is accelerated.The authors have no financial interests related to this publication.     

The Effect of Cimetidine on Verruca Plana Juvenilis: Clinical Trials in Six Patients

Cimetidine is an H₂-receptor antagonist which is mainly used to treat gastrointestinal diseases. Recently, many authors have suggested that cimetidine has the ability to reverse acquired tolerance to dinitrochlorobenzene (DNCB). We have used cimetidine in six patients with verruca plana who showed no therapeutic response to DNCB. Four of them responded and showed complete disappearance of the verruca plana. The mean duration of oral cimetidine administration (1.2 g/day) was 4 weeks until the disappearance. Therefore, we suggest that oral cimetidine can be used as an effective and safe adjunctive modality for the treatment of verruca plana.
