Objective To evaluate the therapeutic efficacy of retrobulbar injection with triamcinolone acetonide (TA) for macular edema caused by retinal vein occlusion (RVO). Design Retrospective case series. Participants 21 eyes of 21 patients with macular edema caused by RVO. Methods Retrobulbar injection with TA 40 mg was performed on 21 eyes. The visual acuity, intraocular pres-sure, fundus fluorescein angiography (FFA) and macular central thickness under the optical coherence tomography (OCT) were recorded and analyzed before and after treatment. The follow-up duration was 6-11 months. Main Outcome Measures The visual acuity and the macular central thickness of OCT. Result Visual acuity was improved at the end of follow-up in 16 eyes (76.2%) and unchanged in 5 eyes (23.8%). Macular central thickness was (287.55±121.70) μm at the end of follow-up and (617.23±185.58) μm before treatment. The difference was statistically significant(P=0.000). After treatment, the comparison of visual acuity and macular central thickness be-tween CRVO patients and BRVO patients, as well as between ischemic RVO patients and non-ischemic RVO patients had no significant difference (P>0.05). In patients of course less than 6 months, the visual prognosis after treatment is better than that of before treatment (P=0.011, 0.01), while in patients of course more than 6 months, no difference of vision could be detected before and after treatment (P= 0.583). The result of FFA showed decrease of fluorescein leakage. During follow-up, intraocular pressure of all patients was in the nor-real range. Recurrence of macular edema was found in 8 eyes 2 to 6 months after treatment. Conclusions Retrobulbar injection with TA is a safe, effective, and easy method to treat macular edema caused by RVO. Early treatment can get better efficacy. (Ophthalmal CHN, 2009, 18: 254-256)

Objective To compare the assessment results of Loewenstein occupational therapy cognitive assessment (LOTCA) and mini-mental state examination(MMSE) in stroke patients,and to analyze the correlation between the two assessments and to explore the applicable values of LOTCA in assessing vascular cognitive function impairment (VCI).Methods According to the diagnostic standard of cognitive impairment with MMSE,thirty stroke patients with cognitive impairment were selected as cognitive impairment group,thirty stroke patients without markedly cognitive impairment as stroke control group,and thirty normal subjects served as normal control group.All the subjects' age,gender and level of education were matched in the three groups. All the subjects were assessed with LOTCA and MMSE.ResultsThe total scores of LOTCA had high positive correlation with the total scores of MMSE in cognitive impairment group ( r =0.934,P < 0.01 ),the correlations were also found between every sub-items of LOTCA and those of MMSE (P < 0.01 ).The total scores and the scores of sub-items of LOTCA in cognitive impairment group were significantly lower than those in stroke control group and were those in normal control group(P < 0.01 ),particularly lower scores in LOTCA sub-items of thinking operations,orientation,visuomotor organization.The scores of sub-items of LOTCA,including thinking operations,visuo-motor organization,attention,orientation,spatial perception were all significantly lower in stroke control group than those in normal control group(P <0.01 ),especially in thinking operations and visuo-motor organization sub-items.Conclusions Correlations were found between LOTCA and MMSE.Compared to MMSE,LOTCA could detect vascular cognitive function impairment earlier and is much more comprehensive,so it is suitable to assess vascular cognitive impairment patients with no dementia.
