ABSTRACT

AIM: To analyze clinical observation and the efficiency of intravitreal conbercept combined with 532-laser on Coats disease in adulthood.METHODS: This was an retrospective analysis.Six eyes from 6 patients(5 males and 1 female) with coats disease diagnosed by fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) were enrolled.Before the injection, best-corrected visual acuity (BCVA) of early treatment of diabetic retinopathy study (ETDRS), non-contact tonometer, ophthalmoscope, fundus photography, FFA, and OCT were examined.The initial average visual acuity (ETDRS letters) were 51.17±15.15.The initial average central retina thickness (CRT) was 303.30±107.87μm.All affected eyes were treated with intravitreal conbercept 0.05mL (10mg/mL) combined with 532-laser.Patients were followed up for 6 to 12mo, with a mean duration of 7.33±1.26mo.Post-treatment BCVA were compared with baseline using repeat analysis.RESULTS: The mean BCVA showed significant improvement during 1 wk, 1, 3mo post-treatment and the latest follow up (P<0.01).During the latest follow up, the mean BCVA was obviously improved in 3 eyes (50%), improved in 2 eyes (40%), stable in 1 eyes (10%).Likewise, the subretina fluid absorption of different levels.No adverse events such as secondary retinal detachment or endophthalmitis were found during the follow-up.CONCLUSION: Coats disease in adulthood more likely to have lower symptom and have a better response on treatment.Intravitreal conbercept combined with 532-laser significantly improve visual acuity and absorb the subretina fluid.
