ABSTRACT
@#AIM: To observe the clinical effect of 25G vitrectomy combined with inner limiting membrane(ILM)peeling in the treatment of severe proliferative diabetic retinopathy(PDR)with macular displacement.<p>METHODS: Clinical data of 36 cases(36 eyes), diagnosed as severe proliferative diabetic retinopathy with macular displacement in Jiangsu Province Hospital were collected. Eighteen cases admitted from January to December 2016 were included in the control group(18 eyes, treated by 25G vitrectomy), while 18 cases admitted from January to December 2017 were included in the combined group(18 eyes, treated by 25G vitrectomy with ILM peeling). Best corrected visual acuity(BCVA), intraocular pressure(IOP), complications, and the thickness of macular center area(CMT)were examined during follow-up at 7d, 1mo, 3mo and 6mo postoperative.<p>RESULTS: BCVA showed a significant improvement at postoperative 6mo compared with baseline in both groups <i>(P</i><0.05). CMT of the combination group was thinner than that of the control group(<i>P</i><0.001). Two eyes(11%)had intraocular hypertension,and 1 eye(6%)had macular edema in the combined group, while post-operative complications included intraocular hypertension(6%),macular membrane(6%)and vitreous hemorrhage(6%)in the control group. No statistical difference was found in the complication rates between the two groups(all <i>P</i>=1.000).<p>CONCLUSION: In the treatment of severe PDR with macular displacement, 25G vitrectomy combined with ILM peeling can effectively and safely improve visual acuity and reduce the thickness of macular center area.
ABSTRACT
@#AIM: To compare the clinical efficacy of two methods for treating refractory glaucoma.<p>METHODS: A total of 30 patients with refractory glaucoma(32 eyes)selected from our hospital from January 2014 to September 2018 were retrospectively analyzed. According to the treatment methods, they were divided into experimental group(16 eyes treated by modified Ahmed glaucoma valve implantation)and control group(16 eyes treated by traditional Ahmed glaucoma valve implantation). The visual acuity, intraocular pressure, number of anti-glaucoma drugs, the success rate, complications and average length of hospitalization were compared between the two groups, during follow-up at post operative 1d, 1wk, 1mo, 3mo and 6mo.<p>RESULTS:There was no significant difference in intraocular pressure between the two groups at post-operative 1d, 1wk, 1mo, 3mo, 6mo(all <i>P</i>>0.05). The total success rate was 87%(14/16)in experimental group while 75%(12/16)in control group(<i>P</i>=0.654). BCVA did not improve significantly at post operative 6 mo compared with baseline in both groups(<i>P</i>>0.05). The average length of hospital stay in the experimental group(4.50±1.37d)was significantly lower than that in the control group(7.63±3.69d)(<i>P</i>=0.003). The incidece of shallow anterior chamber was 31% in control group, while in experimental group, it was 0, which showed significant difference.<p>CONCLUSION: Modified Ahmed drainage valve implantation is an effective method for treating refractory glaucoma, with more simple operations, shorter hospitalizing time and lower incidence of shallow anterior chamber.
ABSTRACT
@#AIM:To compare the efficacy of transscleral cyclophotocoagulation(TSCP)with two different laser parameters.<p>METHODS: A total of 46 cases with refractory glaucoma(46 eyes)who underwent TSCP from January 2014 to December 2018 were analyzed retrospectively. According to the laser parameters, all cases were divided into low-power group(treated by low-power TSCP)and conventional parameter group(treated by conventional parameter TSCP). Intraocular pressures(IOP), best-corrected visual acuity(BCVA), number of anti-glaucoma drugs and complications were observed and compared between the two groups.<p>RESULTS: There was no significant difference of IOP between the two groups at postoperative 1d, 1wk, 1mo and 3mo(all <i>P</i>>0.05). The total success rate was 87% in the low-power group while 83% in the conventional parameter group(<i>P</i>=1.000).The overall incidence of complications of the low-power group(39%)was lower than that of the conventional parameter group(78%)(<i>P</i>=0.007)at postoperative 3mo. The early postoperative pain score of the low-power group was significantly lower than that of the conventional parameter group(<i>P</i>=0.007).<p>CONCLUSION:Compared with conventional parameters, TSCP with lower power may reduce IOP similarly with less pain and fewer complications.
ABSTRACT
@#AIM: To compare the visual acuity, contrast sensitivity and visual quality of cataract patients after the implantation of AT LISA tri 839MP multifocal intraocular lenses and CT SPHERIS 209M monofocal intraocular lenses.<p>METHODS: Fifty-two patients(52 eyes)were involved and divided into two groups in the study. The trail group(26 patients, 26 eyes)received AT LISA tri 839MP multifocal intraocular lens implantation and the control group(26 patients, 26 eyes)received CT SPHERIS 209M monofocal intraocular lens implantation after phacoemulsification. Visual acuity, contrast sensivity at different spatial frequencies(3, 6, 12, 18c/d)in bright and dark circumstances and patient satisfaction questionnaire were monitored at 3mo postoperatively. The postoperative visual acuity included the information of uncorrected distance visual acuity(UCDVA), uncorrected intermediate visual acuity(UCIVA), best corrected distance visual acuity(BCDVA), distance corrected intermediate visual acuity(DCIVA)and distance corrected near visual acuity(DCNVA).<p>RESULTS: The UCIVA, UCNVA, DCIVA, DCNVA, independent spectacles ratio and satisfaction of the trail group were better than those of the control group 3mo postoper atire(<i>P</i><0.05). Mean contrast sensitivity at the spatial frequency of 18c/d in dark circumstances of the control group was higher than that of the trail group(<i>P</i>=0.041). The incidence of glare and halo showed no significantly statistical difference between the two groups(<i>P</i>=0.668).<p>CONCLUSION: AT LISA tri 839MP multifocal intraocular lens provided better intermediate and near visual acuity, independent spectacles ratio and satisfaction compared with CT SPHERIS 209M monofocal intraocular lens.
ABSTRACT
@#AIM: To evaluate the clinical efficacy and safety of transscleral cyclophotocoagulation(TSCP)for glaucoma secondary to vitrectomy. <p>METHODS: A retrospective review was performed within 20 patients(20 eyes)with glaucoma secondary to vitrectomy underwent TSCP in our hospital from October 2014 to October 2016. The follow-up time was 3mo. The postoperative visual acuity, intraocular pressure(IOP)and complications were observed. <p>RESULTS: One month after operation, the postoperative IOP increased in 9 cases. Another 4 eyes were performed TSCP again, and three of them got the normal IOP recovery. At the last follow-up, visual acuity had no significant changes(<i>P</i>=0.655); IOP was effectively controlled in 14(70%)patients. Meanwhile, the mean postoperative IOP(24.6±11.4mmHg)was statistically reduced than the mean preoperative IOP(42.3±5.9mmHg, <i>P</i><0.05). No serious complications, like hypotony and suprachoroidal hemorrhage, had been observed during 3-month follow-up. <p>CONCLUSION: TSCP procedure is a safe, effective, repeatable surgery for patients with glaucoma secondary to vitrectomy.
ABSTRACT
AIM: To analyze and compare the clinical effect in treatment of degenerative entropion of lower eyelid with blepharochalasis between the modified orbicularis oculi muscle shortening procedure and orbicularis muscle shortening procedure.?METHODS:From January 2012 to August 2014, ninety-three cases ( 108 eyes ) diagnosed as involutional entropion of lower eyelid with blepharochalasis were enrolled in our study. According to different surgical methods, patients were divided into observation group (52 eyes in 47 cases) and control group (56 eyes in 46 cases ) . The observation group was performed on the modified orbicularis muscle shortening procedure, and the control group was using a simple orbicularis muscle shortening method. The general datum, short - term clinical effect and long-term clinical effect were collected to compared between two groups.?RESULTS:The age, gender and the course of disease were no significance differences between the observation group and the control group (P>0. 05). There was no statistical significance on the short-term effective rate ( P>0. 05 ) between the observation group and the control group ( 98％ vs 95％, respectively ) . The long - term recurrence rate of the observation group was 2％, while the control group was 14％. It had a significance statistical difference between two groups (P=0. 033).?CONCLUSION: The clinical curative effect of modified orbicularis oculi muscle shortening procedure, in the treatment of lower eyelid entropion with blepharochalasis, is better than the orbicularis muscle shortening procedure's.
