Objective To observe the clinical manifestation and treatment effect of Coatsprime; disease in adulthood. Methods The clinical data of 18 adult patients with Coatsprime; disease from 1980 to 2006 at the department of ophthalmology, Peking Union Medical College Hospital which had been diagnosed by ocular fundus examination and fundus fluorescein angiography (FFA), were retrospectively analyzed. The follow-up period was one year. Coatsprime; response diseases in all the patiens were excluded, such as history of radiation therapy, intraocular inflammation, retinal vascular occlusion, age-related macular degeneration (AMD) and more leakage of diabetic retinopathy. The patients, 14 males and 4 females, 11 left eyes and 7 right eyes, all of them occurs in unilateral; aged from 37 to 55 years with the average age of 43 years; the initial diagnostic vision was 0.02 to 1.5, the visual value was 0.1. 17 patients (17 eyes) were treated by laser photocoagulation, 1 patient was treated by release of retinal operation with condensation. The mean follow up period was 3.7 years (ranged from 1 to 15.3 years). Results In 18 patients (18 eyes), vitreous clear in 14 eyes, vitreous few muddy in 4 years when initial diagnosis. The optic discs in 18 eyes are normal. Lesions confined to one or two quadrant, for the most are in the temporal(15/18 eyes), less are in Bice (4/18 eyes), only one eye at top; two eyes lesions involved in 2 quadrant. There are typical retinal vascular anomalies expansion, miliary aneurysm, arterial aneurysm, macroaneurysms and capillary without perfusion areas; yellowwhite hard leakage by a large block or cluster in Lesion corresponding region. More than half of the eyes with macular edema or leakage; limited retinal detachment in 4 eyes, the range was very wide in 1 eye; retinal hemorrhage in 3 eyes. After treatment the exudation or the hemorrhage were absorbed and retinas were reset. Compared the visual acuity with before treatment, mostly (64.3%) improved 2 lines or keep in 1.2-1.5, no one decreased over 2 lines. The last vision was 0.02-1.5, the visual value was 0.1. Conclusions Coatsprime; disease in adulthood diagnosed in first time has similar characteristics with children, such as vascular anomaly of retina, fundus exudation. The differences including limited area of involvement, less hemorrhages, mild damage on macular, slow development of lesions in follow-up period and better visual prognosis. （Chin J Ocul Fundus Dis，2008，24：279-282）
PURPOSE:Toinvestigate the classification and the age incidence of Coats disease. METHODS:75 cases(79 eyes)of Coats disease were analysed,which were diagnosed by fundus fluorescein angiograpy(FFA)between Jan.1981 and Dec.1994. RESULTS:The patients included 59 males and 16 famales.Average age of the first presentation was 26 years old,and there were 45(60%)cases aged from 19 to 60 years old.In 5 eyes,the ophthalmoscopic examination revealed no obviously abnormal retinal blood vessel,but a number of dilated retinal vessels and microaneuryms were demonstrated by FFA. CONCLUSIONS:The autors consider that there is no essential distinction between type Ⅰand type ⅡCoats disease and it is no longer suitable to apply the traditional classification.Coats disease affects not only juvenile patients but also persons of all ages. （Chin J Ocul Fundus Dis,1996,12: 77-79）
ObjectiveTo study the long-term effects and outcomes of adjuvant intravitreal injection of conbercept (IVC) therapy in juvenile Coats disease. MethodsA retrospective case series study. From January 1, 2015 to December 31, 2018, 40 patients (40 eyes) who were diagnosed as juvenile Coats disease at Beijing Tongren Hospital Affiliated to Capital Medical University were included in the study. Among them, there were 37 males (37 eyes) and 3 females (3 eyes). All patients had unilateral Coats disease. The average age was 55.00 (44.75, 81.25) months. Five eyes were in stage 2B, 15 eyes were in stage 3A, 19 eyes were in stage 3B and 1 eye was in stage 4. Idiopathic retinal vascular telangiectasia associated with extensive subretinal fluid (SRF) (stage 3 or above) or massive foveal exudation and edema (stage 2B) were found in fundus examination. All affected eyes underwent wide-field color fundus images and fluorescein fundus angiography. Thirty-one eyes underwent best corrected visual acuity (BCVA) examination. The BCVA was carried out using a standard logarithmic visual acuity chart, which was converted into the logarithmic minimum angle of resolution (logMAR) visual acuity. All cases received adjuvant IVC combined with treatments such as retinal photocoagulation. The average number of injections was 4 (1, 5). The average follow-up after initial treatment was 59.00 (52.50, 63.00) months. The changes in BCVA, occlusion of abnormal blood vessels in fundus, absorption of SRF and ocular and systemic complications were observed. ResultsAt last follow-up, among 31 affected eyes with the examination of BCVA, 13 (32.5%, 13/40) eyes had an improved vision, 12 eyes(30.0%, 12/40) had a stable vision and 6 eyes (15.0%, 6/40) had a decreased vision. The difference between average logMAR BCVA of the affected eyes in each stage after treatment and that before treatment was not statistically significant (Z=－0.56, －1.80, －0.84; P＞0.05). Abnormal blood vessels in fundus were all partially or completely occluded, and SRF was obviously or completely absorbed in all cases; of which, 28 eyes (70.0%, 28/40) were completely occluded, and 12 eyes (30.0%, 12/40) were partially occluded. No patient underwent eye enucleation. Nineteen eyes (47.5%, 19/40) developed vitreoretinal fibrosis; 8 eyes (20.0%, 8/40) developed tractional retinal detachment; 15 eyes (37.5%, 15/40) developed complicated cataract. None had ocular or systemic complications related to IVC therapy during follow-up. ConclusionsIVC combined with classic treatments such as photocoagulation in juvenile Coats disease can keep or improve the visual acuity in most juvenile patients by reducing SRF. IVC is a long-term safe and effective adjuvant therapy in juvenile Coats disease.
Objective To evaluate the effects of retinal cryotherapy and intravitreal triamcinolone injection to treat Coatsprime; disease with exudative retinal detachment.Methods This was a prospective consecutive case study, and 21 patients (21 eyes) with Coatsprime; disease accompanied by exudative retinal detachment were enrolled. There were 19 males and two females patients, aged from two to 18 years. Fifteen eyes had partial retinal detachment (stage 3A) and six eyes had total retinal detachment (stage 3B). All patients underwent cryocoagulation and intravitreal triamcinolone injection. Three eyes underwent sclerotomy to drain subretinal fluid. Four eyes underwent further treatment by photocoagulation or cryotherapy for the residual abnormal blood vessels after the surgery. The follow-up ranged from three to 15 months with an average of seven months. Visual acuity, intraocular pressure, eye position and eye movements, slit lamp microscope, indirect ophthalmoscope and color fundus imaging were followed up. The last followup time was considered as the judgment time for the therapeutic effects. Results Six eyes had increased intraocular pressure after the surgery, which was controlled by local drug treatment. At the end of follow-up, 19 eyes had reattached retina, one eye had partial retinal detachment and one eye had total retinal detachment. The vision improved in three eyes,unchanged in 14 eyes, and decreased in two eyes. Other complications included strabismus (one eye) and cataract (four eyes). Conclusion The combined treatment of cryotherapy and intravitreal triamcinolone injection is an effective therapy for the Coatsprime; disease with exudative retinal detachment, as retina reattaches and visual function is saved in most patients after this treatment.
