【Abstract】ObjectiveTo improve curative effects in the treatment of hilar bile duct stricture. MethodsIntrahepatic cholelithiasis was associated with the development of hilar bile duct stricture.Plastics of hilar bile duct stricture (PHBDS) using pedicled cholecystic graft and Roux-en-Y cholangiojejunostomy (RYCJ) were performed. The patients with hepatolithiasis treated with PHBDS or RYCJ between Jan. 1994 and Jan. 2004 were retrospectively analyzed.ResultsFollow-up was carried out from 16 months to 87 months with an average of 47 months. The postoperative morbidity of cholangitis was 5.66% and 21.88% (P=0.010) and recurring rate of hepatolithiasis was 3.77% and 16.67%(P=0.021).ConclusionPHBDS can preserve the physiological compatible, convenient and effective in treatment of hilar bile duct stricture. The late result after operation of PHBDS is better than that of RYCJ.
ObjectiveTo evaluate the efficacy of single intravitreal injection of C3F8 in treating vitremacular traction (VMT) syndrome.MethodsA retrospective case series of 38 eyes of 36 patients affected with VMT syndrome in Department of Ophthalmology, Central Theater Command General Hospital from March 2016 to June 2017 were enrolled in this study. There were 16 males (16 eyes) and 20 females (22 eyes), with the mean age of 64.11±9.49 years and the mean courses of 151.55±127.87 days. All the patients received an intravitreal injection of 0.3 ml of 100% C3F8 within one week. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. The severity of metamorphopsia was detected using M-charts. The extent of vitreomacular adhesion (VMA), central macular thickness (CMT) and the status of ellipsoid zone (EZ) were assessed with spectral-domain OCT at baseline and each month after treatment. The average BCVA was 0.58±0.22. The mean horizontal metamorphopsia (MH) and vertical metamorphopsia (MV) were 0.34±0.30 and 0.50±0.42, respectively. The mean CMT was 415.15±89.59 μm. The mean horizontal VMA was 1168.68±400.61 μm (30 eyes with VMA≤1500 μm and 8 eyes with VMA＞1500 μm). The mean vertical VMA was 976.89±295.92 μm. There were 22 eyes with integrity EZ and 16 eyes without integrity EZ, 33 eyes with crystalline lens and 5 eyes with IOL. The mean follow-up time was 10.7 months. The differences in BCVA, MH, MV, CMT, the integrity of EZ before and after treatment were analyzed. The VMT release rates were assessed. The Spearman rank correlation analysis was performed to investigate the relationship of VMT release rates with the data at baseline.ResultsVitreomacular traction release occurred in 29 of 38 eyes by the final follow-up visit, the VMT release rate was 76.3%. VMT release occurred and the average time of VMT release occurred was 2.2 weeks. VMT persisted in 7 eyes, in the rest two eyes, one eye developed a retinal detachment and another eye formed macular hole, both eyes responded to vitrectomy. At 6 months after treatment, the average logMAR BCVA was 0.43±0.23, the mean MH and MV were 0.25±0.23 and 0.24±0.23, the mean CMT was 310.61±63.10 μm. Among 16 eyes without integrity EZ before treatment, there were 9 eyes with integrity EZ at 6 months after treatment. There were 16 eyes with integrity EZ and 9 Compared with baseline, the mean BCVA at 6 months after treatment was significantly increased (F=3.779, P=0.037), but the MV (F=4.958, P =0.003) and CMT (F=13.419, P＜0.001) were significantly decreased, the integrity of EZ was improved significantly (χ2=5.050, P=0.025). The VMT release correlated inversely with the extent of horizontal VMA, BCVA, and CMT at baseline (r=-0.514, -0.348, -0.429; P=0.009, 0.001, 0.038).ConclusionIntravitreal injection of C3F8 can induce a posterior vitreous detachment and release vitreomacular traction, it is an efficient and safe treatment for VMT syndrome. It can improve the visual acuity, metamorphopsia and foveal morphology in patients with VMT syndrome.
Objective To observe the clinical effects of vitreoretinal surgery for myopic foveoschisis, evaluate the visual prognostic factors. Methods Twentyseven eyes of 23 patients with myopic foveoschisis underwent vitreoretinal surgery were analyzed retrospectively. All the patients had undergone the examinations of best corrected visual acuity (BCVA), intraocular pressure, slit lamp microscope, direct ophthalmoscope, binocular indirect ophthalmoscope, A or B ultrasonic scan and optical coherence tomography (OCT). Follow-up duration varied from 6 to 36 months, with the mean of (19.4±10.03) months. The visual acuity, retinal reattachment and the complications were observed. Logistic regression analysis was performed to predict the prognosis of visual acuity. Results Twentyone eyes (7778％) were anatomically reattached, six eyes (2222%) were not anatomically reattached. Postoperative BCVA improved in 24 eyes (8889％), reduced or remained unchanged in three eyes (11.11％). No ocular complications such as fundus hemorrhage, low or high intraocular pressure, endophthalmitis were found. The preoperative BCVA （OR=9.11, P=0.007）, axial length （OR=0.31, P=0.038） and the photoreceptor inner and outer segment (IS/OS) junction line continuity （OR=4。32，P=0.001） are closely related to visual prognosis. Conclusions Vitreoretinal surgery is an effective approach to treat myopic foveoschisis with both anatomical and visual improvement. The preoperative BCVA, axial length and IS/OS line continuity are closely related to visual prognosis.
Objective To investigate the relationship between morphologic macular changes and visual outcome in eyes with persistent submacular fluid (SMF) after surgery for macula-off rhegmatogenous retinal detachment (RRD) and the relevant factors of persistent submacular fluid. Methods Sixty-three consecutive patients (63 eyes) who underwent successful surgery for macula-off RRD were enrolled in this retrospective study. The patients were divided into three groups according to duration of SMF: no SMF group, short-term group (duration of SMF less than three months) and long-term group (duration of SMF more than three months). The follow-up ranged from six to 12 months. The morphologic macular changes, height of SMF and thickness of the outer nuclear layer (ONL) one month after surgery were assessed by spectral domain-optical coherence tomography (SD-OCT). The relationship between morphologic macular changes and logarithm of the minimum angle of resolution (logMAR) visual acuity and the relevant factors of persistent SMF were evaluated. Results Forty-five of 63 eyes (71.42%) presented morphologic changes after surgery. SMF was detected in 32 eyes (50.79%), which included 21 patients that had long-term course of SMF. Irregular thickness of the photoreceptor outer segments (OS) was observed in 23 eyes; disrupted inner segment/outer segment (IS/OS) junction was noted in 21 eyes, and disrupted external limiting membrane (ELM) was noted in 14 eyes. Irregular thickness of OS in long-term group was significantly higher than that in short-term group (chi;2=5.788, P=0.035). The proportion of IS/OS disruption and ELM discontinuation in long-term group was also higher than those in short-term group, but there was no statistically significant difference (chi;2=0.744, 0.375; P=0.472, 0.403). The postoperative visual acuity correlated positively with preoperative visual acuity and the time of retinal detachment (r=0.611, -0.374; P=0.007, 0.037). There was a significant difference of postoperative logMAR visual acuity (U=28.640, P=0.049) among no SMF group (0.27plusmn;0.26), short-term group (0.42plusmn;0.31) and long-term group (0.53plusmn;0.41). The postoperative visual acuity was insignificantly associated with irregular OS and IS/OS disruption (r=0.331, 0.320; P=0.073, 0.102). The irregular OS correlated positively with IS/OS disruption (r=0.388, P=0.027). The postoperative visual acuity in eyes with disrupted both IS/OS and ELM significantly decreased (U=29.920, P=0.036). The surgery manner (r=0.477, P＜0.001), time of preoperative retinal detachment (r=0.354, P=0.047) and SMF height one month after surgery (r=0.375, P=0.039) were factors influencing persistent SMF. Conclusions The incidence of postoperative photoreceptor lesion was increased with time of persistent SMF. Disruption of both IS/OS and ELM after surgery means a poorer vision outcome. Duration of preoperative macular detachment, type of surgery and SMF heights one month after surgery were important factors for persistent SMF.
Objective To evaluated the efficacy of vitreoretinal surgery for X-linked retinoschisis (XLRS) and its complications. Methods Twentyone XLRS patients (27 eyes) with retinal detachment or vitreous hemorrhage who were treated by vitreoretinal surgery were enrolled in this study. There were microcystislike splitting in all the eyes. The mean visual acuity was 0.11±0.09 and the mean area of macular splitting was (1.09±0.56) mm2. Among the eyes, there were 12 eyes with rhegmatogenous retinal detachment, five eye with traction retinal detachment, six eyes with vitreous hemorrhage and four eyes with retinal detachment and vitreous hemorrhage. All the patients underwent a standard threeport pars plana vitrectomy. Internal limiting membrane peeling, laser photocoagulation, and C3F8 gas or silicone oil tamponade were carried out in different condition. The follow-up was 9-122 months (average 51 months). The preoperative visual acuity and anatomic structure of retina were observed. Results The mean visual acuity at last visit was increased to 0.26±0.15, the difference was significant (t=-6.320, P=0.000). It improved in 20 eyes (74.1%), remained unchanged in seven eyes (25.9%). The retina remained attached in 27 eyes. The mean area of macular splitting was decreased to (0.29±0.21) mm2, the difference was significant (t=10.358, P=0.000). The complications were found in four eyes (14.8%) which including two eyes with proliferative vitroretinopathy and traction retinal detachment six and eight months after surgery, one eye with cataract four months after surgery, and one eye with vitreous hemorrhage 15 months after surgery. The retina remained attached in these four eyes after reoperation. Conclusion Vitreoretinal surgery can significantly improve visual acuity, resume the anatomic structure of retina.
Objective To evaluate the clinical efficacy of oral calcium dobesilate(CaD) on diabetic optic neuropathy (DON).Methods The clinical data of 235 eyes of 235 patients with DON diagnosed by examination of ocular fundus were retrospectively analyzed.The patients were divided into 3 groups according to the subtypes of DON: anterior ischemic optic neuropathy(AION)group(71 eyes of 71 patients), papilloedema group (71 eyes of 71 patients),and neovascularization of disc (NVD) group (93 eyes of 93 patients).The patients in each groups were randomly subdivided into CaD treating group and control group, in which the patients underwent oral administraion of CaD at a dose of 500 mg twice per day or Vit.E at a dose of 10 mg twice per day,respectively.The course of therapy was 6 months and consecutive 2 courses were performed with the 3-4 days interval between the courses; the courses lasted for 6 months.Several parameters (VFD/V),EA/d,NA/d,LA/d) were semiquantitative analyzed 2,4,6,8 months after initial treatment. Repeated ANOVA measures and t test were used as statistical methods.Results In CaD group,VFD/V (0.25plusmn;0.10),EA/d (0.94plusmn;0.53), and LA/d(1.83plusmn;1.12) 2 months after initial treatment was obviously better than the results before the treatment (0.49plusmn;0.13,1.57plusmn;0.71,3.42plusmn;1.88)(P＜0.001), respectively.VFD/V,EA/d and LA/d in CaD group 2,4,6,and 8 months after initial treatment significantly differed from which in the control group (P＜0.01). There was significant difference of VED/V,EA/d,and LA/d between the CaD and control group during the follow-up period (P＜0.01).At each time point in the followup period, there was no significant difference of NA/d among groups and between the treating and control group (P＞0.05).Conclusion Oral administration of CaD can rapidly and remarkably decrease the extent of visual field defect,relieve optic disc edema and lessen the leakage of NVD.
ObjectiveTo compare the efficacy among 30% and 50% dose of verteporfin photodynamic therapy (PDT) and intravitreal anti-vascular endothelial growth factor (anti-VEGF) in the treatment of chronic central serous chorioretinopathy (CSC). Methods138 eyes of 125 patients with chronic CSC, who were treated in our hospital from March 2006 to May 2014, were enrolled in this retrospective study. All patients were confirmed by spectral domain optical coherence tomography (SD-OCT) and best corrected visual acuity (BCVA), which was recorded with logMAR BCVA. And all the patients were divided into three groups by different treatments: 30% dose group (42 eyes of 39 patients); 50% dose group (77 eyes of 67 patients); anti-VEGF group (19 eyes of 19 patients). The differences of age, gender, eyes, courses, mean logMAR BCVA among three groups were not significant. Disappearing of fluid under retina in SD-OCT was considered to be cured and fluid remaining was not cured. If fluid appeared again the eyes were relapsed. We comparatively analyzed the cure rate, relapse rate and changing of BCVA, central macular thickness (CMT) among 3 groups of patients after 1, 3, 6 months. ResultsThe cure rate among 3 groups after 1 month was statistically different (χ2=6.926, P=0.031). The cure rates of 50% dose PDT treatment group after 3 months and 6 months were better than 30% dose PDT treatment group, but the differences were not significant (χ2=2.218, 1.682; P=0.136, 0.195). The relapse rate between 30% dose and 50% dose PDT treatment groups after 3 months and 6 months were not significant (χ2=2.133, 3.366; P=0.144, 0.067). The improvement of BCVA in 50% dose PDT treatment group was the best, but comparing with the other two groups, the differences were not significant in statistics (P > 0.05). The improvement of CMT in 50% dose PDT treatment group was the best. Comparing with anti-VEGF group, the differences was significant (P < 0.05). But comparing with 30% dose PDT treatment group, the differences was not significant (P > 0.05). Logistic regression analysis showed that after treatment, the cure rates after 1 month and 6 months were negatively correlated with the age (regression coefficient=-0.942, -0.979; odds ratio=0.390, 0.375; P < 0.05) and the cure rates after 3 months was positively correlated with the dose of verteporfin (regression coefficient=0.855, odds ratio=2.351, P < 0.05). Conclusion50% dose verteporfin PDT is recommend for chronic CSC treatment.
ObjectiveTo evaluate the efficacy of 30% and 50% dose photodynamic therapy (PDT) for acute central serous chorioretinopathy (CSC). MethodsA retrospective cohort study. Ninety-two eyes of 88 patients with CSC, diagnosed by best corrected visual acuity (BCVA) of logarithm of the minimum angle of resolution (logMAR), indirect ophthalmoscope, fundus colorized photography, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA)and optical coherence tomography (SD-OCT) treated with 30% and 50% doses of verteporfin respectively between March 2007 and August 2013, were enrolled. The eyes were divided into 50% dose group (49 eyes) and 30% dose group (43 eyes). The differences of age (t=-1.45), gender (χ2=0.011), eyes (χ2=2.140), mean logMAR BCVA (t=-0.40), mean central retinal thickness (CRT) and the maximum thickness of serous retinal detachment (SRD) between two groups were not significant (P > 0.05). The difference of spot size between two groups was significant (t=-2.84, P < 0.05). The follow-up time was ranged from 6 to 68 months, with a mean of (17.16 ±11.30) months. The difference of follow-up between two groups was significant (P > 0.05). The BCVA, cure rate, recurrence rate and the changes of CRT and maximum SRT were observed by SD-OCT. ResultsThe subretinal fluid (SRF) of 31 eyes (72.09%) in the 30% dose group and that of 47 eyes (95.92%) in the 50% dose PDT group was absorbed completely respectively. The cure rates in the 30% dose PDT group was significantly less than that in the 50% dose group (χ2=10.077, P=0.020). There was a significant negative association between the cure rate and spot size by Logistic regression (odds ratio > 1, P=0.040). The difference of changes in the BCVA of logMAR in 50% dose group was better than that in 30% dose group after more than 12 months after PDT (P=0.036). On 3, 6, 12 and more than 12 months after PDT, the difference in CRT in 50% dose group and 30% dose group were not statistically significant (P=0.068, 0.060, 0.082, 0.067). The difference in maximum thickness of SRD was not statically significant (P > 0.05). SRF was appeared in 8 eyes (25.81%) of 31 eyes in the 30% dose group, while SRF was appeared in 1 eye (2.13%) of 47 eyes in the 50% dose group. The recurrence rate of 30% dose group was much higher than that of 50% dose group (P < 0.05). ConclusionsFor acute CSC treated by PDT, the curative effect of 50% dose group is better than the 30% dose group.
