Glaucoma Certification in California, Texas and Pennsylvania

"Glaucoma certified" sounds like one credential. It is not. In most states, treating glaucoma is part of a therapeutic license; in others it is a separate certification with its own application, fee, continuing education and, in Pennsylvania, its own insurance minimum and license number. California, Texas and Pennsylvania are the three large states where an optometrist moving in most often has to deal with glaucoma as a distinct step, so they are worth reading side by side.

How does California label glaucoma authority?

California prints certification letters next to the license number. The board's fact sheet defines five:

• DPA: diagnostic pharmaceutical agents for examination only.
• TPA: therapeutic pharmaceutical agents and the procedures listed in Business and Professions Code § 3041.
• TPL: TPA plus lacrimal irrigation and dilation for patients over 12.
• TPG: TPA plus diagnosis and treatment of primary open angle glaucoma in patients over 18.
• TLG: both the lacrimal and the glaucoma additions.

An out-of-state optometrist chooses certifications in Part 2 of the application, after passing the California Laws and Regulations Exam (CLRE). Part 2 fees as of October 2026 are $25 for TPA, $50 for TPL and $50 for TPG or TLG, on top of Part 1 ($275 plus $4 for the NPDB query). TMOD is required for TPA and every higher license type. Glaucoma and lacrimal certifications for an existing licensee are requested through BreEZe.

The certification also changes renewal. Every TPA-certified optometrist needs 50 hours of CE every two years, 35 of them on diagnosis, treatment and management of ocular disease. TPG and TLG holders must include 10 hours of glaucoma-specific CE within those 35 (16 CCR § 1536(l)). California does not accept practice management courses, even COPE-approved ones.

What is the Texas Optometric Glaucoma Specialist?

Texas law lets a therapeutic optometrist be certified as an Optometric Glaucoma Specialist through specialized training and certification of skills. The Texas Optometry Board has decided that everyone who graduated from an accredited optometry school after 2008 is qualified. Since Jan. 1, 2025, qualified new applicants must apply for the glaucoma certification at the same time as the therapeutic license, so most recent graduates moving to Texas receive both together. Applicants who graduated in 2008 or earlier can still be licensed as therapeutic optometrists without it, and the certification has its own application on the board's site.

The underlying license is the Acceptance Application ($205), filed on NBEO Parts I, II and III plus TMOD, with the Texas Jurisprudence Exam taken through NBEO, fingerprints, an NPDB self-query, CPR or BLS, and a 2-hour course on prescribing and monitoring controlled substances. The application asks for your OE TRACKER number and board access on the NBEO site. Texas also has you attest that the information "has been personally provided and reviewed by me," so the answers have to be yours. See Texas optometry licensing.

What are Pennsylvania's P, T and G licenses?

Pennsylvania issues three levels: P (diagnostic), T (therapeutic) and G (therapeutic plus glaucoma). Glaucoma authority came with Act 225 of 2002, which lets board-certified optometrists treat primary open angle, exfoliation and pigmentary glaucoma. The board's mailer on Act 225, revised June 6, 2025, sets out the path:

1. Therapeutic certification first. An optometrist without T certification gets it before applying for G. Therapeutic certification needs 100 hours of pharmaceutical training and a passed exam.
2. Glaucoma CE if you qualified the older way. Optometrists who earned therapeutic certification through a stand-alone 100-hour course and the TMOD exam (Category Two) complete 18 hours of board-approved glaucoma CE. Those whose pharmaceutical education and NBEO testing came with graduation (Category One) skip this step. The board notes that NBEO first tested pharmaceuticals on April 1, 1993.
3. Liability coverage. Every glaucoma applicant verifies coverage of at least $1,000,000 per occurrence and $3,000,000 annual aggregate.
4. The application and fee. 49 Pa. Code 23.91 lists $25 each for therapeutic and glaucoma certification, beside the $25 license application. Renewal is $135 every two years.

Two details catch people. A G certification issues a new license number, so preprinted prescription pads need reordering. And CE shifts: every licensee needs 30 hours every two years including 2 in child abuse recognition, T licensees need 6 in pharmaceuticals, and G licensees need 4 in glaucoma. Pennsylvania licenses NBEO holders without a years-of-practice test, and the board lists no law exam. See Pennsylvania licensing and the G license.

Which other states issue glaucoma as its own credential?

A few more are worth knowing when you plan a move:

• New Hampshire adds TPA or TPA/G (glaucoma) certification to the license for $25.
• Nevada issues prescribing (OPAC) and glaucoma as separate certificates, and offers glaucoma certification by endorsement.
• Rhode Island grants amplified therapeutic privileges for glaucoma after consultation with an experienced glaucoma prescriber on at least 20 glaucoma patients.
• Massachusetts lists DPA, TPA and TPA with glaucoma.
• Maine issues new licensees only the therapeutic advanced glaucoma license; graduates before October 1996 need added glaucoma and pharmacology coursework.

South Carolina works the other way: it does not issue glaucoma separately, but it requires endorsement applicants to be authorized to treat glaucoma where they practice now. That makes glaucoma authority in your current state a gate, not an add-on.

Does glaucoma certification in one state carry over to another?

Not automatically. Each board decides glaucoma authority under its own act. Your current certification, school transcript, NBEO TMOD score and CE history are evidence for the new board, and in Texas your graduation year may settle it outright. In Pennsylvania the category you fall into decides whether you need 18 more hours. If your home state's glaucoma scope is narrower than the new state's, see when your home state's scope is narrower.

When should the glaucoma step happen?

With the license, if the board allows it. California asks for certifications in Part 2, Texas requires qualified applicants to apply for both together, and Pennsylvania's G application follows T certification. Filing them separately months apart means a period where you are licensed but cannot manage glaucoma patients in that state, which matters if the job you are moving for is a medical practice.

How can we help?

The Therapeutic, Glaucoma or Legend Drug Certification Add-On is $249 per certification, usually filed alongside the license ($699 per state). We assemble the education records, score reports, CE certificates and proof of coverage, and track the board; you answer and sign the application. Start with a readiness review ($149) or the state pages for California, Texas and Pennsylvania. For the therapeutic and orals layer underneath, read what TPA, orals and legend drug certificates mean.
