Purpose: To assess features and outcomes of Coats disease over 5-decades. Methods: Retrospective review of Coats disease patients at a single center. Features and outcomes were compared based on decade of presentation. Results: There were 351 patients with Coats disease. The presenting median age (6 years), male sex (84%), and unilaterality (100%) did not change per decade. Coats disease classification did not change per decade with Stage 1 (1%), Stage 2 (21%), Stage 3 (68%), Stage 4 (6%), and Stage 5 (1%). Clinical features that changed per decade (1970s vs. 1980s vs. 1990s vs. 2000s vs. 2010s) included 1980s features of more eyes with exudation in all 4 quadrants (22% vs. 58% vs. 44% vs. 33% vs. 27, P = 0.01) and total exudative retinal detachment (33% vs. 53% vs. 39% vs. 27% vs. 21%, P < 0.001). Imaging features that changed per decade included 2010s greater fluorescein angiographic extent of retinal non-perfusion in mean clock hours (4 vs. 4 vs. 3 vs. 5 vs. 6, P = 0.003), and 1980s greater mean height of retinal detachment ultrasonographically (5 vs. 12 vs. 5 vs. 5 vs. 4 mm, P < 0.001). Treatment features that changed per decade included 1980s greater primary enucleation (11% vs. 16% vs. 3% vs. 4% vs. 1%, P = 0.001), and 2010s greater use of laser photocoagulation (55% vs. 33% vs. 38% vs. 40% vs. 72%, P < 0.001), sub-Tenon corticosteroid (0% vs. 4% vs. 5% vs. 8% vs. 29%, P < 0.001), and intravitreal anti-VEGF) (0% vs. 4% vs. 2% vs. 13% vs. 18%, P = 0.003). Outcomes that changed per decade included 2010s findings of more complete resolution of subretinal fluid (64% vs. 59% vs. 38% vs. 58% vs. 72%, P = 0.01) and less need for primary/secondary enucleation (17% vs. 27% vs. 14% vs. 13% vs. 6%, P = 0.04). Conclusion: Eyes with Coats disease in the 1980s demonstrated more advanced findings, often requiring enucleation. Over the decades, greater use of laser photocoagulation and injections has led to improved disease resolution with greater globe salvage.
Purpose: To investigate features and outcomes of Coats disease by patient age. Methods: Patients with Coats disease from 1973 to 2018 were evaluated based on age category at presentation (3 years or younger vs older than 3 to 10 years vs older than 10 years). Results: There were 351 eyes of 351 patients with Coats disease diagnosed (2 vs 6 vs 27 years, P < .001). The youngest age group had more referral diagnoses of retinoblastoma (29% vs 15% vs 0%, P < .001), worse presenting visual acuity (< 20/200: 80% vs 67% vs 31%, P < .001), more advanced Coats disease stage (stage 3B: 65% vs 38% vs 10%, P < .001), and greater clock-hour extent of telangiectasia (7 vs 5 vs 4, P < .001), light bulb aneurysms (7 vs 4 vs 3, P < .001), exudation (10 vs 7 vs 5, P < .001), and subretinal fluid (10 vs 7 vs 4, P < .001). The oldest patients received a greater total number of treatments (3.3 vs 3.1 vs 4.4, P = .04), with more argon laser photocoagulation (37% vs 52% vs 73%, P < .001) and intravitreal anti-vascular endothelial growth factor (6% vs 9% vs 23%, P < .002) and less cryotherapy (74% vs 84% vs 58%, P < .001). At mean follow-up (70 vs 65 vs 38 months, P = .02), the youngest patients had poorer visual acuity outcome (< 20/200: 83% vs 64% vs 39%, P < .001), had less disease resolution (43% vs 65% vs 62%, P = .01), and were more likely to ultimately require enucleation (22% vs 10% vs 6%, P = .01). Conclusions: Younger patients (3 years or younger) with Coats disease present with worse visual acuity and more advanced disease stage, and are more likely to require ultimate enucleation.

PurposeTo assess visual outcomes of Coats disease by classification stage.MethodsA retrospective review was conducted on consecutive patients with Coats disease, classified according to Shields classification and with available Snellen visual acuity before and after treatment.ResultsThere were 160 eyes with Coats disease (stage 1 (n=2) vs stage 2A (n=17) vs stage 2B (n=22) vs stage 3A1 (n=26) vs stage 3A2 (n=40) vs stage 3B (n=42) vs stage 4 (n=9) vs stage 5 (n=2)). By comparison, more advanced stage showed greater frequency of poor presenting visual acuity (<20/200) (0% vs 0% vs 50% vs 35% vs 38% vs 83% vs 100% vs 100%, p<0.001) and higher mean intraocular pressure (17 vs 15 vs 15 vs 15 vs 15 vs 15 vs 37 vs 26, p<0.001). More advanced stage was less likely managed with laser photocoagulation (100% vs 87% vs 48% vs 62% vs 74% vs 35% vs 0% vs 0%, p<0.001) and more likely with cryotherapy (0% vs 47% vs 81% vs 81% vs 82% vs 88% vs 50% vs 100%, p=0.001). More advanced stage was associated with lower frequency of visual acuity ≥20/40 (100% vs 71% vs 5% vs 42% vs 23% vs 5% vs 0% vs 0%, p<0.001) and greater frequency of visual acuity <20/200 (0% vs 12% vs 36% vs31 % vs 45% vs 88% vs 0% vs 100%, p<0.001).ConclusionVisual acuity in eyes with Coats disease parallels staging with more advanced stage demonstrating poorer visual acuity at presentation and final visit.
