Coats disease associated with vasoproliferative tumor treated with cryotherapy and intravitreal injections of triamcinolone / Doença de Coats associada a tumor vasoproliferativo tratada com crioterapia e injeções intravítreas de triancinolona

Abstract Report of a case of Coats disease associated with retinal vasoproliferative tumor in a young female patient with two peripheral vascularized tumors and lipid exudation involving the macula and peripapillary region with serous retinal detachment areas and pre-papillary fibrous proliferation. The proposed and performed treatment was the intravitreal injection of triamcinolone acetonide to decrease the tumor exudation, followed by photocoagulation of the peripheral areas of telangiectasia without subretinal fluid and cryotherapy of the tumors. Despite that this is a rare and difficult to treat combination, in this case report, success was obtained in receding the tumor masses and reapplying the retina, leading to anatomic and visual stabilization.

Resumo Relato de um caso de Doença de Coats associada a tumor vasoproliferativo de retina em uma paciente jovem com duas tumorações vascularizadas periféricas e exsudação lipídica acometendo mácula e região peripapilar com áreas de descolamento de retina seroso e proliferação fibrosa pré-papilar. O tratamento proposto e realizado foi a injeção intra-vítrea de triancinolona para diminuir a exsudação do tumor, seguida de fotocoagulação periférica das áreas de telangiectasia sem fluido subretiniano e criocoagulação dos tumores. Apesar de se tratar de uma associação rara e de difícil tratamento, neste relato de caso, obteve-se êxito em regredir as massas tumorais e reaplicar a retina, levando à estabilização anatômica e visual.

Quantitative analysis of biochemical components in the suprachoroidal space fluid of choriodal detachment associated with rhegmatogenous retinal detachment / 中华眼底病杂志

Objective To investigate the nature of the suprachoroidal fluid by detecting the concentration of total protein (TP), lactate dehydrogenase (LDH), albumin (ALB), total cholesterol (CHOL), total bilirubin (TBIL) in suprachoroidal liquid of patients who have rhegmatogenous retinal detachment with choroid detachment (RRDCD). Methods Eighteen RRDCD patients (18 eyes) who underwent vitrectomy were enrolled in this study. There were 10 males (10 eyes) and 8 females (8 eyes), 8 right eyes and 10 left eyes. There were 8 patients with age of ≤55 years, 10 patients with age of >55 years. There were 7 patients with duration of≤30 days, 11 patients with duration of >30 days. There were 7 eyes with diopters of ≥-6.0 D, 11 eyes with diopters of <-6.0 D. There were 11 eyes with class C proliferative vitreoretinopathy (PVR), 7 eyes with class D PVR. Suprachoroidal fluid samples were collected from all the patients, and took preoperative serum samples as RRDCD group. Ten serum samples of normal people were set as control group. The concentration of TP, LDH, ALB, CHOL, TBIL in all the subjects were measured. The properties of the suprachoroidal fluid were identified by Light standard and concentration standard of ALB, CHOL, TBIL. Results There was no difference on the concentration of TP, LDH, ALB, CHOL, TBIL from suprachoroidal fluid samples in the patients with different age, sex, eyes, diopter, PVR grade (P>0.05). There was no difference on the concentration of TP, LDH, ALB, CHOL, TBIL from preoperative serum samples in the patients between RRDCD group and control group (P>0.05). There was no difference on the concentration of ALB and CHOL from suprachoroidal fluid samples and preoperative serum samples in the RRDCD patients (P>0.05), but there were significant differences on the concentration of TP, LDH, TBIL (P<0.05). According to the Light standard, there were 17 cases of exudates and 1 case of transudate. According to the concentration standard of ALB, CHOL and TBIL, there were 14, 18, and 16 cases of exudates, and 4, 0, and 2 cases of transudate, respectively. There was no difference on the identification result of Light standard and concentration standard of ALB, CHOL, TBIL (χ2=2.090, 1.029, 0.364;P>0.05). Conclusion The suprachoroidal fluid of RRDCD patients composed of TP, LDH, CHOL and TBIL. The suprachoroidal fluid is more likely to be exudate.

Etiology study of retinal detachment after silicone oil removal / 中华眼底病杂志

Objective To evaluate the incidence of retinal re-detachment and possible risk factors after removal of silicone oil.Methods The clinical data of 821 patients (858 eyes) who underwent removal of silicone oil in General Hospital of PLA during 2008-2012 were retrospectively analyzed.The patients included 518 males and 303 females.The age was ranged from 1 to 79 years old,with an average of 44.03 years.All patients underwent removal of silicone oil after vitrectomy combined with silicone oil tamponade (the tamponade period was ranged from 40 days to 13 years,with an average of 6.82 months).The incidence,time and causes of retinal re-detachment were analyzed.Results Retinal re-detachment occurred in43 patients (44 eyes,5.13％).Among these retinal re-detachment in 44 eyes,23 eyes (52.27％) occurred in 1 week,13 eyes (29.55％) in 1-4 weeks,4 eyes (9.08％) in 4-8 weeks,2 eyes (4.55％) in 8-12 weeks,and 2 eyes (4.55％) more than 12 weeks after silicone oil removal.Possible reasons of retinal re-detachment included activated original retinal holes (7 eyes),residual peripheral vitreous (3 eyes),traction of epiretinal proliferative membrane (18 eyes),new retinal hole (9 eyes),non-closure of original retinal holes (5 eyes) and traction of retinal incarceration in the scleral incision (2 eyes).Conclusions The incidence of retinal re-detachment after silicone oil removal is 5.13 ％.The incidence reduced gradually with the extension of time after removal silicone oil.

Causes and risk factors of recurrent retinal detachment after silicone oil removal / 中华眼底病杂志

Objective To investigate the main causes and risk factors of recurrent retinal detachment (RRD) after silicone oil removal (SOR) in eyes with complex retinal detachment.Methods It was a retrospective case series study.A total of 458 eyes of 455 consecutive patients who underwent pars plana vitrectomy with silicone oil tamponade were recruited in this study.All patients underwent vitrectomy operation.Additionally,they were given heavy water,membrane peeling,retinotomy or partial cutting,intraocular laser photocoagulation or frozen,gas-liquid exchange or direct oil exchange operation accordingly.Ninety-eight eyes with multiple holes,old retinal detachment,hyperplasia and serious traction lesions underwent scleral buckling surgery simultaneously.Intravitreal silicone oil was padded at the end of operation.Cutting,stripping or resection and 360° preventive laser photocoagulation were applied while the epiretinal membrane was found and need treatment during SOR.Holes or suspicious hiatus underwent intraocular laser photocoagulation or cryotherapy during the operation.One week after SOR and during follow-up,the visual acuity,intraocular pressure (IOP),slit lamp microscope,and ophthalmoscope examination were examined with the same technique and methods as preoperation.The eyes were divide into two groups based on the attachment status of retina after SOR,which were reattached group (419 eyes) and redetached group (39 eyes) respectively.The following data were recorded.,the age of patients,ocular axial length,logarithm of minimum angle of resolution (logMAR) best corrected visual acuity (BCVA) and IOP before vitrectomy operation and before and after SOR,the number of retinal breaks,the duration of silicone oil filling,the duration of follow-up,and the related factors during vitrectomy operation and SOR.The relation of age,sex,high myopia,the size and location of holes,aphakic eye,proliferative vitreoretinopathy (PVR) C3 level and above,previous history of failed retinal detachment operation,360° preventive laser photocoagulation,assistant scleral buckling surgery,SOR via corneal puncture to RRD after SOR were analyzed.Odds ratio (OR) and its 95％ confidence interval (CI) were calculated for the age ＜40 years old and gender.High myopia,assistant scleral buckling surgery and SOR via corneal puncture were further analyzed by multiple regression equation.Results After SOR operation,the total average logMAR BCVA was 0.86 ± 0.63.The average logMAR BCVA was 0.82 ± 0.59 and 0.99 ± 0.70 respectively for the reattached and redetached groups,which was not statistically different (F=1.559,P＞0.05).The number of high myopia eyes in the reattached and redetached groups were 116 and 22 eyes,respectively,accounted for 27.7 ％ and 56.4 ％,and the difference was statistically significant (x2=13.984,P＜0.01).Three eyes underwent vitrectomy with scleral buckling occured RRD,accounting for 3.1％; while 36 eyes underwent vitrectomy without scleral buckling occured RRD,accounting for 10.0％.The incidence of RRD between them was statistically significant (x2 =4.761,P＜0.05).The incidence of RRD was not retated to the PVR levels before the operation,previous history of failed retinal detachment operation,aphakic eye and preventive laser photocoagulation (OR=1.626,1.699,1.986,0.709; 95％ CI:0.836-3.162,0.832-3.658,0.921-4.279,0.268-1.875; P＞0.05).RRD had a close relation with high myopia and assistant scleral buckling surgery (OR=3.380,0.284; 95％CI:1.733-6.595,0.086-0.944; P＜0.05).The raise of risk derived from SOR via corneal puncture had no statistical significance (OR=2.119; 95％CI:1.043-4.306; P＞0.05).The incidence of RRD after SOR was 8.5％; of which,35.9％ originated from new breaks and 69.2％ were related to new breaks,in contrast,only 5.1％ originated from PVR but 51.3％ were related to PVR.Conclusions High myopia is an independent prognostic risk factor of RRD after SOR.Combined scleral buckling surgery is a protective factor of RRD after SOR.To the well reattached eyes before SOR,the new breaks seems to be the main cause of RRD,wheras PVR was probably a secondary phenomenon.

Clinical characteristics and therapeutic effect of retinal detachment in aphakic and pseudophakic eyes in 805 patients / 中华眼底病杂志

Objective To observe the clinical characteristics and therapeutic effect of aphakic retinal detachment (ARD) eyes and pseudophakic retinal detachment (PPRD) eyes.Methods The clinical data of 805 patients,including 321 ARD and 484 PPRD eyes were retrospectively analyzed.The patients'visiual acuity,refraction,intraocular pressure were examined,and the patients also underwent slit-lamp microscopy and direct and (or) indirect ophthalmoscopy.The preoperative best-corrected visual acuity (BCVA) was between light perception (LP) and 0.6.Mainly according to the PVR grade and retinal holes position to take the scleral buckling or vitrectomy combined with scleral buckling.The 805 eyes were divided into 1995-1999 group (243 eyes) and 2000-2007 group (562 eyes) according to operative time.The follow-up ranged from 3 to 25 months,with an average of 12.3 months.The success standard of surgery was set as anatomic retinal reattachment and the last follow-up time was considered as the judgment time.The surgical complications were recorded at each follow-up time points.The composition of PPRD,the visual acuity,ocular lesions,surgical methods and results before operation and visual acuity after operation in two groups were analyzed and compared by Mantel-Haenszel chi-square test.Results The average interval from lens extraction to RD occurrence was 15.4 months in PPRD eyes and 39.1 months in ARD eyes.The final total anatomic success rate was 95.9%,and was 93.5% in the scleral buckle eyes and 97.2% in vitrectomy eyes.The BCVA was better than 0.3 after operation only in 11.9% of the 805 patiens,and the visual acuity increased more than 2 lines in 67.3%.Compared with the ARD eyes,early onset,high proportion of total posterior vitreous detachment,severe PVR,wide RD range,low detection rate of retinal hole and low antomic success rate were found in PPRD eyes.Compared with the 1995-1999 group,the proportion of vitreous surgery,anatomic success rate and better visual acuity were found in 2000-2007 group.Conclusions The ocular lesions of ARD and PPRD is more complicated,the therapeutic effect are improving in recent years.
