ABSTRACT

AIM: To investigate the effect of modified Chufeng Yisun Decoction on ocular surface inflammation after pterygium surgery.METHODS: A total of 60 patients(60 eyes)with primary pterygium who underwent pterygium surgery were randomly divided into control group and study group, with 30 cases(30 eyes)in each group. In the control group, patients were treated with pranoprofen eye drops, tobramycin dexamethasone eye drops, and deproteinized calf blood extract eye gel after the surgery. In the study group, patients were treated by oral modified Chufeng Yisun Decoction in addition to the treatments in the control group. The changes of ocular irritation symptoms, ocular inflammatory signs, tear interleukin 6(IL-6)levels, and tear ferning test(TFT)of patients in the two groups were assessed.RESULTS: The visual analogue scale(VAS)in patients of both groups was significantly lower at 2d and 1wk after the surgery than that at 1d after the surgery(all P<0.01), and the VAS of the study group was significantly better than that of the control group at 2d and 1wk after surgery(P<0.01). The ocular signs integrals(OSI)and TFT results of both groups at 1wk were significantly lower than those at 1d after the surgery(all P<0.01), and the OSI and TFT were also lower in the study group than in the control group at 1wk after the surgery(all P<0.01). In addition, the concentration of tear IL-6 in both groups was significantly lower at 1wk after the surgery than 1d after the surgery(all P<0.01), and it was also significantly lower in the study group than in the control group at 1wk after the surgery(P<0.05).CONCLUSION: The combination of Chufeng Yisun Decoction and conventional treatment of western has a better effect on controlling ocular surface inflammation after pterygium surgery.

ABSTRACT

Blepharitis is one of the common eye diseases,it may cause ocular irritation symptoms,and even cause damage of visual function,if it involves the meibomian gland and cornea.Recent studies have shown that Demodex infestation may be an important but under-estimated cause of blepharitis,its diagnosis and treatment become the focus of blepharitis research,clinical doctors should pay adequate attention to this.Demodex blepharitis still faces many uncertain problems and challenges.In this paper,the controversial problems of Demodex blepharitis diagnosis and treatment,combined with domestic and foreign research results and the author's experience was analyzed,and we also discussed that how to improve the accuracy of clinical diagnosis and improve the treatment effect of Demodex blepharitis.Herein,we emphasize on the diagnosis and treatment options of Demodex blepharitis.Early detection of the pathogen and prompt treatment would ultimately improve the prognosis of Demodex blepharitis.

ABSTRACT

PURPOSE: To investigate the relationships between tear osmolarity and various parameters for ocular and systemic disease in primary Sjögren's syndrome. METHODS: The medical records of 53 patients with primary Sjögren's syndrome were reviewed. Tear osmolarity using a TearLab® (TearLab™ Corp., San Diego, CA, USA) osmometer as well as other dry eye parameters such as tear break-up time, ocular staining score (Sjögren's International Collaboration Clinical Alliance [SICCA] ocular staining score, SICCA score), Schirmer-I score, symptoms with Ocular Surface Disease Index (OSDI), and Visual Analog Scale (VAS) were obtained. Systemic laboratory data and medication history were also collected. The correlations between the parameters were analyzed using the Spearman's rank correlation test. RESULTS: 53 patients with a mean age of 54.1 ± 13.2 years and female predominance (96.23%) were enrolled. The majority of patients (28.3%) were receiving systemic therapy for severe Sjögren's syndrome. The tear osmolarity in Sjögren's syndrome patients was 307 ± 13.6 (mOsm/L). Higher tear osmolarity was associated with lower tear film break-up time (BUT) scores and with higher SICCA scores. Tear osmolarity and the Schirmer test results were not significantly related. Higher tear osmolarity was paradoxically associated with lower VAS scores and lower OSDI scores. Neither current medication nor the salivary gland focus score showed significant associations with tear osmolarity. Although tear osmolarity was not associated with the SSA-Ro or SSA-LA titer, serum immunoglobulin G (IgG) level and serum erythrocyte sedimentation rate (ESR) level showed positive correlations with tear osmolarity. CONCLUSIONS: Tear osmolarity is positively correlated with the severity of dry eye and was associated with lower symptom severity. The significant associations of tear osmolarity with IgG and ESR suggest that high tear osmolarity may be correlated with autoantibody load and the systemic inflammatory state.

ABSTRACT

Currently,antimicrobial resistance has become an urgent global public health problem.Human defensin,a family of innate immune peptides,plays an important role in the control of infectious disease because of its low resistance to microbiological infection.However,so far there is seldom report on industrial production of bioactive defensin.Human β-defensin 3 (HBD3) is a member of human innate antimicrobial peptides.It has broad-spectrum antimicrobial activity and function in a variety of inflammation diseases.In addition,HBD3 is considered as a good candidate for antibiotics,because it has a strong killing activity to antibiotics-resistant microbes and resistance to highsalt environment,it is especially valuable for the treatment of ocular surface inflammatory diseases.This review covers the in vitro research on the production of HBD3,optimization of structure-activity and its antimicrobial potential for ocular surface infection,which may provide a supportive evidence for the commercial production of HBD3 and other antimicrobial peptides in biopharmaceutical area.

ABSTRACT

PURPOSE: To evaluate the effects of cheap tinted contact lenses on corneal swelling and ocular surface inflammation, compared to hydrogel and silicone hydrogel contact lenses. METHODS: Forty eyes of 20 New Zealand white rabbits were randomly assigned to 4 groups. Two types of tinted contact lenses, hydrogel lenses, and silicone hydrogel lenses were each applied to 10 rabbit eyes. Corneal thickness and tear lactate dehydrogenase (LDH) activity were measured at 1 and 4 days after contact lens wear, and the inflammation of ocular surface was scored at 4 days after contact lens wear. The internal surface of the cheap tinted lens was examined with a scanning electron microscope to compare the surface quality between the tinted and non-tinted area. RESULTS: Although the corneal swelling of the silicone hydrogel lens group was significantly lower than the other 3 lens groups after contact lens wear (p0.1). Tear LDH activity at 1 and 4 days after contact lens wear showed no significant difference among the 4 groups (p>0.29). The scores of ocular surface inflammation in the 2 tinted contact lens groups were greater than the hydrogel and silicone hydrogel lens groups (p=0.03). The scanning electron microscope revealed the internal surface of the tinted area in the tinted contact lens was coarse and irregular though the surface of the non-tinted area was relatively smooth. CONCLUSIONS: Regarding corneal swelling and tear LDH activity, the cheap tinted contact lenses used in Korea were not significantly different from the common hydrogel contact lenses. However, tinted contact lenses showed a greater tendency to provoke ocular surface inflammation than other lenses. The coarse and irregular surface of the tinted area in the tinted contact lens appears to play a role in provoking severe ocular surface inflammation.
