[Changing patterns of surgical treatment for glaucoma in the Eye Hospital of Wenzhou Medical University during the past ten years].

Objective: To investigate the patterns of surgical treatment for patients with glaucoma in the Eye Hospital of Wenzhou Medical University from 2005 to 2014. Methods: Retrospective case series about 6 781 glaucoma patients (7 751 eyes) who received surgical treatment from January 1, 2005 to December 31, 2014 in the Eye Hospital of Wenzhou Medical University. Among them, 2 869 were males and 3 912 were females, aged (62±14) years. The data of patients' demographic information, diagnosis and surgical procedures [trabeculectomy, aqueous shunts of ExPRESS and Ahmed for extraocular reservoir, cataract extraction with intraocular lens (IOL) implantation, and combined operations for glaucoma and cataract] were collected and the patterns of surgical treatment were evaluated. SPSS 21.0 statistical software was used, mainly for statistical description of the data. Results: The ratio of trabeculectomies increased between 2005 and 2009, from 48.2% (95/197) to 57.7% (488/846), but decreased to 21.1% (220/1 041) in 2014. The ratio of aqueous shunts of ExPRESS and Ahmed increased to 6.1% (63/1 041) and 7.6% (79/1 041) from 2005 to 2014, respectively. The ratio of cataract extraction with IOL implantation increased to 28.4% (294/1 036) in 2012, but decreased to 21.6% (225/1 041) in 2014. The ratio of combined operations for glaucoma and cataract decreased to 6.6% (47/717) from 2005 to 2010, and increased to 36.6% (381/1 041) in 2014. Over the decade, the ratio of cataract extraction with goniosynechialysis increased from 2.4% (15/623) to 17.7% (184/1 041). The rate of iridotectomy decreased to 0.2% (2/1041) in 2014. Conclusions: Trabeculectomy, cataract surgery and combined surgery for glaucoma with cataract were still the mainstream of glaucoma surgery in the Eye Hospital of Wenzhou Medical University from 2005 to 2014. And the ratio of cataract extraction with IOL implantation, aqueous shunts of ExPRESS and Ahmed, and combined operation for glaucoma and cataract rapidly increased, with cataract extraction with goniosynechialysis increasing most rapidly and becoming the mainstream procedure of treatment for glaucoma and cataract. Inversely, the rate of trabeculectomies and iridotectomies decreased dramatically over this period.(Chin J Ophthalmol, 2018, 54: 184-188).

[Changing trends of topical anti-glaucoma medications in the Eye Hospital of Wenzhou Medical University during the past ten years].

Objective: To investigate the changing trends of topical anti-glaucoma medications in the outpatient of the Eye Hospital of Wenzhou Medical University over the decade 2005-2014. Methods: Retrospective case series study. The medications data of glaucoma outpatients in the Eye Hospital of Wenzhou Medical University were collected for the period of January 1(st) 2005 to December 31(st) 2014. SPSS 20.0 statistical software was used, mainly for statistical description of the data. The main outcome measures were the proportions of the prescriptions of different medications, and the proportions of the monotherapy and combination therapies. Results: During the 10 years, the number of glaucoma outpatients increased year by year, from 994 in 2005 to 3 266 in 2014, the gender ration was close to 1∶1, and the age were (57±18) years. The proportion of ß-blockers decreased from 56.7% (750/1 323) in 2005 to 33.1% (2 120/6 407) in 2014. The proportion of cholinergic agents decreased from 17.2% (227/1 323) in 2005 to 10.3% (663/6 407) in 2014. While the proportion of prostaglandins increased from 13.3% (176/1 323) in 2005 to 36.8% (1 916/5 209) in 2011, which was close to the 37.9% (1 972/5 209) of ß-blockers in 2011. In 2012, the prostaglandins proportion increased to 41.9% (2 435/5 810) exceeding the 37.2% (2 161/5 810) of ß-blockers, and became the most prescribed medication. The proportion of prostaglandins continued to increase to 46.9% (3 008/6 407) in 2014. The proportion of α(2)-agonists increased from 17.0% (225/1 323) in 2005 to 22.8% (1 460/6 407) in 2014. The proportion of carbonic anhydrase inhibitors increased from 9.6% (127/1 323) in 2005 to 24.1% (1 546/6 407) in 2014.The proportion of monotherapy decreased from 78.0% (1 032/1 323) in 2005 to 58.6% (3 757/6 407) in 2014. The proportion of two drugs combination increased from 20.0% (264/1 323) in 2005 to 26.7% (1 709/6 407) in 2014. The proportion of three drugs combination increased from 2.0% (26/1 323) in 2005 to 12.3% (788/6 407) in 2014. The proportion of four drugs combination increased from 0.1% (1/1 323) in 2005 to 2.3% (150/6 407) in 2014. Conclusions: The changes of the proportions of topical anti-glaucoma medications were remarkable from 2005 to 2014 in the outpatient of the Eye Hospital of Wenzhou Medical University. The ß-blockers and cholinergic agents were declining, while the prostaglandins, α(2)-agonists and carbonic anhydrase inhibitors were increasing, and the prostaglandins became the most prescribed medication since 2012. The proportion of combination therapy was increasing. (Chin J Ophthalmol, 2018, 54: 520-525).

Mucinous metaplasia of the penis.

AIMS: To determine the incidence of mucinous metaplasia occurring in the foreskin or glans penis and any associated clinical or histopathological features. METHODS AND RESULTS: Following the recognition of two index cases, 100 other foreskin specimens were retrieved from the histopathology archives at Southampton General Hospital. The haematoxylin and eosin-stained slides were examined by a single observer to detect the presence of mucin-producing cells in the surface epithelium. The absence of mucinous metaplasia in negative cases was confirmed with mucin histochemistry. In total, four cases of mucinous metaplasia were identified, three involving the foreskin and one involving the glans penis. The age range was 51-80 years. Three cases were associated with Zoon's balanitis and the fourth showed mild non-specific balanitis. All four cases showed positive staining with both diastase periodic acid-Schiff and alcian blue. No mucin-producing cells were identified in non-inflamed or minimally inflamed specimens. CONCLUSIONS: Mucinous metaplasia of the penis is an uncommon but under-recognized condition. It is seen in the elderly and appears to be a metaplastic change associated with severe chronic inflammation, and possibly more specifically with Zoon's balanitis. Our study identified a case affecting the glans penis, a site not previously recorded.
