To evaluate the therapeutic safety, efficacy and feasibility of treating Coats’ disease with non-vitrectomized vitrectomy.


15 patients (15 eyes) diagnosed with Coats’ Disease between December 2012 and October 2013 were included in this study. There were 13 males (86.7%)and 2 female(13.3%) patients, aged from 7 months to 18 years (average 6.7years). All of the 15 eyes were complicated with shallow retinal detachment. We performed operations with minimal invasions: made two 23G ports 3mm posterior to the limbus of cornea, applied laser directly on the abnormal blood vessels and injected viscoelastics afterwards. 5 eyes were treated combined with intravitreal triamcinolone injection and five with lucentis injection.(Figure1 A,B,C,D). 2 eyes undertook this surgury after drainage of the subretinal fluid (Figure2 E,F,G,H).


The follow-up ranged from 2 to 10 months. Visual acuity, intraocular pressure, eye position, slit lamp microscope, indirect ophthalmoscope and color fundus imaging were followed up. At the end of follow-up, 15 eyes had reattached retina, the abnormal blood vessels subsided with laser spots and one eye had an increased intraocular pressure.(Figure 3,4,5)


Minimally invasive operations of intraocular photocoagulation combined with intravitreal triamcinolone injection is a safe, efficacious and feasible way to treat Coats’ disease with shallow detachment. Others impact of the technique needs further investigation.
