METHODS: Sixteen corneas of 16 rats were chemically cauterized and randomized into four groups: bevacizumab group that treated with 0.05mL/1.25mg bevacizumab, ranibizumab group that treated with 0.05mL/0.5mg ranibizumab, pegaptanib group that treated with 0.05mL/0.15mg pegaptanib sodium, and control group that treated with 0.05mL saline solution. Digital photographs of the corneas were taken and analyzed using an image analysis software program. All corneas were excised and examined histologically on the 15 th day. RESULTS: Each treatment group had significantly less neovascularized corneal areas and fewer blood vessels than the control group (all P 【0.05). In addition, bevacizumab group had significantly less neovascu-larized corneal areas and fewer blood vessels than ranibizumab and pegaptanib groups (both P 【0.05). However, there was no significant difference between the ranibizumab and pegaptanib groups regarding percentage of neovascularized corneal areas and number of blood vessels (both P 】0.05). CONCLUSION: Subconjunctival bevacizumab, ranibiz-umab, and pegaptanib sodium were effective with no corneal epitheliopathy for inhibiting corneal neovascularization after corneal burn in rats .Bevacizumab was more effective than ranibizumab and pegaptanib sodium.展开更多

Early phase took the samples in 24 h after instillation and late phase took the samples between 4 to 14 d after the start of treatment. The study use of topical SEMA3A(10 U, 100 U,1000 U) eye drops and subconjunctival injection of SEMA3 A with same concentration. For comparison, five types of allergy eyedrops were quantified using clinical characteristics.· RESULTS: Clinical score of composite ocular symptoms of the mice treated with SEMA3 A were significantly decreased both in the immediate phase and the late phase compared to those treated with commercial ophthalmic formulations and non-treatment mice. SEMA3 A treatment attenuates infiltration of eosinophils entering into conjunctiva in EAC mice. The score of eosinophil infiltration in the conjunctiva of SEMA3 A 1000 U-treated group were significantly lower than low-concentration of SEMA3 A treated groups and non-treated group. SEMA3 A treatment also suppressed T-cell proliferation in vitro and decreased serum total Ig E levels in EAC mice. Moreover, treatment of SEMA3 A suppressed Th2-related cytokines(IL-5, IL-13 and IL-4)and pro-inflammatory cytokines(IFN-γ, IL-17 and TNF-α)release, but increased regulatory cytokine IL-10 concentration in the conjunctiva of EAC mice.CONCLUSION: SEMA3 A as a biological agent, showed the beneficial activity in ocular allergic processes with the less damage to the intraocular tissue. It is expected that SEMA3 A may be contributed in patients with a more severe spectrum of refractory ocular allergic diseases including allergic conjunctivitis in the near future.展开更多

Methods: A 68-year-old man presented to the ophthalmology clinic, complaining of redness, foreign body sensation and lacrimation in the left eye since 1 week. Slit-lamp examination disclosed a subconjunctival whitish cord like structure with movement. Presentation, clinical, surgery removal, and treatment are described. Results: At the time of surgery, an alive and still intact worm was extracted through conjunctiva incision. Conclusions: As a not yet known endemic region, we would like to emphasize the importance of this zoonosis with its ocular manifestation, knowing previously the diagnostic difficulties. From this perspective, we conclude that the incidence of ocular dirofilariasis may be much higher than that is reported in our region.展开更多

Vision improved to normal in all the eyes following surgical/ medical/optical treatment. ·CONCLUSION:Evidence of penetrating injury (because of thorns) and blunt injury (because of weight) can be seen in the eyes when durian fruit falls on the face. Vision can be recovered fully with immediate and appropriate treatment in these cases. The ocular injuries can be prevented by educating the public to wear protective metal frame wide goggles and not to sleep/take rest under the durian tree.展开更多

METHODS: A total of 400 patients were randomized into 2 groups; Group A(200 patients) received 5 mg SCTA at the end of surgery and topical ketorolac tromethamine(0.5%) with ofloxacin(0.3%) combination for 3 wk. Group B(200 patients) received tapering topical loteprednol etabonate(0.5%) along with ofloxacin(0.3%) and ketorolac tromethamine(0.5%) for 3 wk. Outcomes evaluated were intraocular pressure(IOP), anterior chamber cells/flare and macular oedema postoperatively at 1, 6 and 12 wk.RESULTS: Baseline parameters were almost similar in both the groups. No statistical difference was seen between the preoperative and postoperative IOP values for Group A(P=0.82) and Group B(P=0.61) and postoperative IOP values in between both groups(P=0.14) at 1 wk. Incidence of cells/flare postoperative was statistically not significant(P=0.82) in both groups at all follow up visits. Postoperative macular oedema was not observed at any follow up visit. CONCLUSION: SCTA appears to be an effective alternative to prolong postoperative topical steroid use.展开更多

文摘Background:To study the effect of an ab interno gelatin stent(XEN45 Gel Stent,Allergan Inc.,Irvine,California,USA)on intraocular pressure(IOP)as placed by glaucoma fellowship trainees in eyes with refractory glaucoma.Methods:A prospective noncomparative study at a tertiary training center on 28 unique eyes undergoing ab interno gelatin stent implantation by glaucoma fellowship trainees.Data was collected at baseline and postoperatively at day 1,week 1,and months 1,3,5,and 12.Primary outcome was mean IOP change.Secondary outcomes included change in number of glaucoma medication classes and visual acuity.Safety outcomes included needling rates.Surgical success was defined by achieving≥20%reduction in IOP with the same or fewer classes of antiglaucoma medications from baseline without the need for secondary surgical intervention and/or stent removal.Results:At baseline,28.6%(8/28)of the subjects had prior failed incisional glaucoma surgery in a study population that was 54%African-American,with 78%with severe glaucoma(average mean deviation of−14.58 dB).Thirteen subjects terminated their clinic visits before their 12-month postoperative visit,leaving 15 subjects for end point analysis.Average IOP went from 21.6 mmHg(range 12.0–31.0,SD 6.6)at baseline to 12.5 mmHg(range 7.0–19.0,SD 3.6),a 42.1%reduction(p<0.007).All subjects decreased the number of medication classes they were taking with an average reduction of 3.8(range 2–5,SD 0.9)to 1.3(range 0–3,SD 1.0)classes,or a 65.8%decrease(p<0.006).Crude surgical success was 80.0%for the 15 subjects that followed up at 12 months.The Kaplan-Meier cumulative probability of success for all 28 subjects at 12 months was 70.4%(95%CI:44.7–85.8%).Regardless of the length of follow-up,21.4%(6/28)met failure criteria:3 subjects failed because they required secondary surgical intervention,and the other 3 did not have adequate IOP reduction.Initial bleb needling rate was 28.6%(8/28)and repeat was 17.9%(5/28).Conclusions:Compared to the reported literature with experienced
