Primary Practice Patterns for the Initial Management of Open Angle Glaucoma.

Prcis: About one-fourth of survey respondents from an ASCRS database initiate treatment for primary open angle glaucoma (POAG) with laser trabeculoplasty. Factors impacting physicians' choice of laser versus topical treatment for POAG were explored.
Purpose: To characterize primary treatment preferences (topical medication versus laser trabeculoplasty or intracameral sustained release implants) in primary open angle glaucoma (POAG) patients and determine factors related to primary intervention selection.
Methods: A 33-question survey was distributed to an American Society of Cataract and Refractive Surgery database on treatment choices made by ophthalmologists for POAG. Data collected included country of practice, years of practice, completion of glaucoma fellowship training, type of practice, and preference for the first line of treatment for POAG. Multiple logit regression was used to compare the effect of covariates on physicians' choice of either topical medication or laser trabeculoplasty for POAG.
Results: A total of 252 of 19,246 (1.3%) surveys were returned. Almost three-quarters of respondents used topical medication as the first line of treatment for POAG (73.6%), whereas 26.4% preferred to start with laser treatment. Significant variables associated with the selection of laser (vs. drops) are practicing in the United States (odds ratio [OR] 2.85; 95% CI, 1.33-6.10), the more recent completion of ophthalmology residency (OR 1.95; 95% CI, 1.00-3.77), the greater volume of minimally invasive glaucoma surgeries (MIGS) (OR 1.68; 95% CI, 1.18-2.40), and a glaucoma patient base greater than 25% (OR 2.21; 95% CI, 1.09-4.48).
Conclusions: For the first-line treatment of POAG, laser trabeculoplasty is more likely to be preferred, over topical drops, by U.S. physicians who are relatively new in practice, who have a larger glaucoma patient base, and who perform more MIGS.
