Abstract

Purpose: To quantify and to analyze the relative cost of various glaucoma surgical procedures and selective laser trabeculoplasty surgery per mm Hg intraocular pressure (IOP) reduction ($/mmHg) since standard cost-utility methods are not well suited to the study of glaucoma which characteristically only claims visual acuity in its end stages. Methods: Published glaucoma treatment studies were reviewed to quantitate the reduction of mean IOP and glaucoma medications for a given treatment modality. A United States perspective was adopted, using Medicare allowable costs were used to calculate a newly introduced parameter - cost per mmHg IOP reduction- at 1 year postoperatively. Results: The cost per mmHg IOP reduction after one year of treatment ranged from $190/mmHg for trabeculectomy to $1376/mmHg for iStent. For reference, the cost of selective later trabeculoplasty surgery was $121/mmHg. After the first year, cost/mmHg ranged from $12/mmHg to $61/mmHg. Conclusions: Conventional glaucoma surgeries and SLT surgery were the most cost-efficient surgical methods to lower intraocular pressure compared to the various MIGS options. They may be more appropriate management when cost is an important issue.
