Objective To observe the effect of pars plana vitrectomy (PPV) with epiretinal membrane peeling (ERMP) and (or) internal limiting membrane peeling (ILMP) and silicone oil tamponade for highly myopic macular hole retinal detachment (MHRD) with posterior staphyloma. Methods Eighty-five highly myopic MHRD patients (85 eyes) were enrolled in this study. All the patients were examined for corrected visual acuity (CVA), slit lamp microscope and preset lens, indirect ophthalmoscope, A/B ultrasound, optical coherence tomography (OCT) and intraocular pressure examination. The average axial length was (29.1plusmn;1.8) mm. There were 24 eyes with diffuse choroid atrophy and 61 eyes with partial choroid atrophy. The CVA was converted into a logarithm of the minimal angle of resolution (logMAR) for statistical analysis. The average logMAR CVA was 1.93plusmn;0.37. All the patients were treated with PPV and triamcinolone acetonide or indocyanine green (ICG) assisted ILMP and (or) ERMP and silicone oil tamponade. TA assisted ERMP was performed in 21 eyes; with ICG assisted ILMP in 56 eyes and TA assisted ILMP in eight eyes. The duration of silicone oil tamponade was (6.2plusmn;1.6) months. CVA, retina and macular hole status and complications were observed postoperatively. Differences between preoperative and postoperative CVA were evaluated by the t test and correlation analysis. Multiple logistic regression analysis was performed to assess the influence of individual preoperative factors on the initial anatomical success. Differences in the macular hole closure rate between eyes with or without macular schisis were evaluated for statistical significance using corrected chi-square. Results The mean logMAR CVA was 1.34plusmn;0.48 after surgery, which significantly improved compared to that before surgery (t=39.38, P＜0.01). The CVA after surgery was independent of axial length (r=0.142, P＞0.05), choroid atrophy (t=0.23, -0.165,P＞0.05) and macular hole closure (t=0.12, -0.005, P＞0.05). The retina reattached in 79 eyes (92.9%) and recurrence of retinal detachment occurred in six eyes (7.1%). Multiple logistic regression analysis indicated that recurrence of retinal detachment was independent of choroid detachment, proliferative vitroretinopathy, axial length, choroid atrophy and ILMP (OR=1.428, 5.039, 0.815, 2.578, 0.432; P＞0.05). Of these 85 eyes, macular hole closed in ten eyes (11.8%), macular hole did not close in 75 eyes (88.2%). There were 24 eyes (28.2%) experienced high intraocular pressure during the first 2 weeks after surgery, all of them were under control with drugs. There were 12 eyes (14.1%) presented with high intraocular pressure before the silicone oil removal, all of them were under control only by silicone oil removal. Conclusion For the treatment of MHRD with posterior staphyloma, PPV combined with ERMP and (or) ILMP and silicone oil tamponade show a high retinal reattachment rate.
Objective To explore the clinical manifestations and the characteristics of images of indocyanine green angiography (ICGA) and fundus fluorescein a ngiography(FFA) of multifocal choroiditis. Methods Eight patie nts (10 eyes) with multifocal choroiditis were gathered. The clinical manifestations and the images of ICGA and FFA were analyzed. Results Foci of multifocal choroiditis were found in posterior pole and peripheral areas of ocular fundi of all of the 10 eyes. The images of ICGA revealed hypofluorescence in focal area. The images of FFA showed hypofluorescence at the early phase and fluorescein leakage at the late phase in the active focus, and fluorescein staining and window defect fluor escence in the inactive focus. Conclusions The clinical manife stations of multifocal choroiditis varied with disease course, location and numbers of the lesions. ICGA and FFA can show the development of the disease clearly, which may guide the treatment. (Chin J Ocul Fundus Dis，2004，20：87-89)
Objective To evaluate the visual prognostic factors in vitreoretinal surgery for diabetic tractional retinal detachment (DTRD). Methods 102 eyes of 86 consecutive patients with DTRD underwent vitreoretinal surgery were analyzed retrospectively. All cases diagnosed via indirect ophthalmoscope and B ultrasonic scan after mydriasis. Followup duration varied from 12 to 56 months (mean: 23 months). Best corrected visual acuity (BCVA) and anatomic success were observed postoperatively. The patients were divided into visual acuity improved group and didn't improved group. Ttest, Chisquare test and Multivariate Logistic regression analysis were performed to predict the prognosis of visual acuity. Results After primary vitreoretinal surgery, 87 eyes (85.3%) were anatomically reattached, 15 eyes (14.71%) needed reoperation because of the recurrence of retinal detachment (RD). Postoperative BCVA improved and better than 0.05 in 49 eyes (48.04%), reduced or increased but less than 0.05 in 53 eyes (51.96%). Comparing natural factors between these two groups, only combined cataract surgery and optic nerve atrophy were significant different (chi;2=5.266,9.274;P=0.022,0.002). Among post-operative complications only the RD recurrence was significant different (chi;2=12.059，P=0.000). Multivariate Logistic regression revealed recurrence of RD and optic nerve atrophy were two independent risk factors in the final BCVA (P=0.003,0.041;OR=33.518、4.079). Preoperative PRP was identified as the only protecting variable in the final BCVA(P=0.034，OR=0.270).Conclusion This study revealed recurrence of RD and optic nerve atrophy were two independent risk factors in final BCVA of DTRD patients.
Objective To observe the changes of tortuosity and bifurcation angle of retinal arteries and veins in each quadrant of the posterior pole in eyes with high myopia.Methods The tortuosity and bifurcation angle of retinal vessels in each quadrant of the posterior pole in 32 patients (52 eyes) with high myopia and 22 healthy people (30 eyes) were observed and compared. The outcomes were analyzed by multivariate analysis of variance. Results The tortuosity of macular vessels and the artery from optic disc in eyes with high myopia was (1.29plusmn;1.10)times;10-4 and (5.39plusmn;1.93)times;10-5 respectively, and in the normal eyes was (4.15plusmn;2.38) times;10-4 and (9.75plusmn;4.99)times;10-5 respectively; there was significant difference between the two groups （t=1.99, 2.00;Plt;0.05）. The bifurcation angle of superior nasal and inferior nasal retinal arteries in eyes with high myopia was（66.17plusmn;14.04）deg; and (61.20plusmn;11.02) deg; respectively, and in the normal eyes was （77.66plusmn;14.12）deg; and (85.86plusmn;16.45) deg; respectively; there was significant difference between the two groups （F=0.77, 0.83; Plt;0.05）. The bifurcation angle of superior temporal and inferior temporal retinal veins in eyes with high myopia was（92.39plusmn;20.36）deg; and (83.56plusmn;23.50) deg; respectively, and in the normal eyes was （79.45plusmn;15.94）deg; and (70.59plusmn;17.27) deg;; there was significant difference between the two groups （F=2.34, 1.83; Plt;0.05）.Conclusions The vessel tortuosity of retinal arteries and the vessels extending from the optic disc to macula is smaller in eyes with high myopia, while the venous tortuosity has no change. The bifurcation angle of retinal arteries in the superior nasal and inferior nasal field was smaller in eyes with high myopia, while the venous tortuosity has no change. The bifurcation angle of retinal veins in the superior temporal and inferior temporal field was larger in eyes with high myopia.
ObjectiveTo systematically review whether or not obstructive sleep apnea hypopnea syndrome (OSAHS) increases the incidence of atrial fibrillation in coronary artery disease patients.MethodsPubMed, EMbase, The Cochrane Library, SinoMed, CNKI, VIP and WanFang Data databases were searched for studies on the relationship between OSAHS and the incidence of atrial fibrillation in coronary artery disease patients from inception to July 2nd, 2018. Two reviewers independently screened literatures, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed by RevMan 5.3 software.ResultsIn total, 11 cohort studies were included, involving 709 in exposed group and 975 in non-exposed group. The results of meta-analysis indicated that OSAHS was associated with the incidence of atrial fibrillation in coronary artery disease patients (RR=2.01, 95%CI 1.72 to 2.36, P<0.000 01). The subgroup analysis showed that OSAHS of PSG diagnosis increased the risk of the incidence of atrial fibrillation in coronary artery disease patients (RR=2.40, 95%CI 1.84 to 3.12, P<0.000 01); moderate and severe OSAHS of PSG diagnosis had higher risk of the incidence of atrial fibrillation in coronary artery disease patients (RR=3.73, 95%CI 2.51 to 5.53, P<0.000 01); high risk OSAHS of Berlin questionnaire assessment increased the incidence of atrial fibrillation in CAD patients (RR=1.56, 95%CI 1.27 to 1.92, P<0.000 1).ConclusionThe current evidence indicates that OSAHS is associated with an increased risk of atrial fibrillation in coronary artery disease patients. Due to the limitation of quality and quantity of the included studies, more large-scale and fine quality research are needed to warrant the accuracy of conclusion above.
