GLAUCOMA SEVERITY SCALE DEFINITIONS
• Mild Stage: optic nerve changes consistent with glaucoma but NO visual field abnormalities on any visual field test OR abnormalities present only on short-wavelength automated perimetry or frequency doubling perimetry.
• Moderate Stage: optic nerve changes consistent with glaucoma AND glaucomatous visual field abnormalities in one hemifield and not within 5 degrees of fixation.
• Severe Stage: optic nerve changes consistent with glaucoma AND glaucomatous visual field abnormalities in both hemifields and/or loss within 5 degrees of fixation in at least one hemifield.

Managing Glaucoma Patients
• Monitor IOP reduction: 1-2 week, 1 month
• Check IOP every 3-4 months
• Repeat VF every 6-12 months
• Disc photos every 1-2 years
• Gonioscopy every year
• Optic nerve analysis every 6-12 months
• Document everything

When Do I Use Electrophysiological Tests?
•Clarify Differential Diagnosis…. Is it Systemic or Trauma vs. Ocular?
•When Standard Tests are Unattainable or Unreliable
•When Other Tests are Inconsistent or Borderline Result
•To Monitor Subclinical Disease for Functional Changes and Alter Treatment and Efficacy
VEP (neuro)
PERG (retinal)
Electrophysiology objectively measures strength and speed of the visual signal to the

ELECTROPHYSIOLOGY DETECTS CHANGES EARLIER THAN OCT AND VISUAL FIELD1
Non structural damage documented
Visual Evoked Potential (VEP)
• Main Indications• Glaucoma
• Multiple Sclerosis
• Ischemic Optic Neuropathy
• Traumatic Brain Injury
• Amblopyia
• Other Neuropathies
WHY USE VEP?
• VEP is an objective, functional test when standard tests cannot provide sufficient information for diagnosis and treatment.
• Many optic nerve diseases are asymptomatic because central vision is not affected until late in the disease1
• Diagnosis and management of optic nerve disorders are often based on structural or subjective visual field tests2

Abnormal VEP

Low contrast demonstrates changes to the magnocellular pathway -Earliest functional degradation shown in glaucoma patients!!
P100 Signal Delayed
Pattern ERG = PERG
Main Indications
Glaucoma
Maculopathies
Can also help the clinician differentiate between retinal and optic nerve disorders when used in conjunction with Visual Evoked Potential (VEP).
How Does PERG Work?
Since the PERG (in contrast to the flash ERG) is a local response from the area covered by the retinal stimulus image, specifically GCC, it can be used as a sensitive indicator of dysfunction within the macular region and it reflects the integrity of the optics, photoreceptors, bipolar cells and retinal ganglion cells.

3 Quick Steps To Report Interpretation

Sinusoidal Peaks – Look for 3 humps
Abnormal PERG
Missing 3 humps

Peripheral Iridotomy (PI) Glaucoma: Laser Treatment
•Open or Narrow Angle Glaucoma•Transcleral Cyclophotocoagulation
Considerations for Optometry
• Laser therapy remains a viable option

• Glaucoma comanagement considerations
Advances in Glaucoma Surgery
•Evolution of small-incision phacoemulsification techniques and small-profile IOLs• Smaller wounds, less inflammation
•Using antimetabolites to enhance filtration surgery• MMC intra-operatively• 5-FU post-operatively with needling/injections
•Availability of novel glaucoma procedures• Non-penetrating glaucoma surgeries (Trabectome,
canaloplasty)• Endocyclophotocoagulation
Glaucoma Pre-surgical Considerations
• Review health status and medications
• Anticoagulants
• Coughing
Cataract and Glaucoma
•How to position the cataract operation in the management scheme of the patient’s glaucoma condition?
• Is it better to choose one sequence and type of surgery before the other, or to combine two procedures?
•STRESS the IMPORTANCE of visual fields PRIOR to cataract surgery
2/12/2017
13
Selecting the Appropriate Surgical Approach
• For vast majority there are 3 choices:
1. Undergo cataract extraction alone, pay no surgical attention to glaucoma condition
2. Undergo glaucoma filtering surgery first and allow full healing before a second operation for cataract removal
3. Undergo a single combined cataract and IOL implantation operation at the time of the glaucoma filtering surgery
IOL Choices in Glaucoma
“Yes – I would like to be free from glasses!”
STANDARD
MULTIFOCALTORIC
Traditional glaucoma surgery
Trabeculectomy
•Traditionally done when meds and/or lasers fail to adequately control the pressure
• In advanced cases can be first line mode of treatment
•Gold Standard Surgical technique• Long history
• Low eye pressures
• Reduce or eliminate medications and costs
Candidates for Trabeculectomy
•Optic nerve progression despite MMT and/or LT
•Visual field progression despite MMT and/or LT
• Inability to take drops adequately
•Target pressure is LOW
•Moderate/advanced disease
Trabeculectomy Procedure
•Surgical exposure
•Conjunctival flap
•Scleral flap - +/- antifibrosis agent
•Sclerostomy
• Iridectomy – needed to prevent the iris from incarcerating into the internal ostium
•Scleral flap closure
•Conjunctival closure

Trabeculectomy Complications
•Scar formation-failure
•Bleb leak
•Blurring of vision
•Hypotony
•Choroidal hemorrhage
• Infections
•Cataract formation
Tube Shunt and Cataract Surgery
Standard Surgical Treatments
Tube Shunt- Advantages
• Safer for contact lens wearers
• More standardized post operative care
• Used when previous trabeculectomy failed
• Results comparable to trabeculectomy
Tube Shunt Advantages
•Safer for contact lens wearers
•More standardized post operative care
•Used when previous trabeculectomy failed
•Results comparable to trabeculectomy
Filtering Surgery Alternatives:Express Shunt

15
Why Express Shunt over Simple Trabeculectomy?
• Trabeculectomyprocedure: • A sclerostomy under the
scleral flap with two to three punches with a Kelly Descemet’s punch
• Surgical peripheral iridectomy
• Ex-PRESS implantation:• The above steps skipped • Instead, implant inserted through a
27g needle tract• Less inflammation• More standardization• Less time• Less early hypotony• Fewer complications• Similar IOP results
Maris PJG Jr, Ishida K, Netland PA. Comparison of trabeculectomy with Ex-PRESS miniature glaucoma device implantedunder scleral flap. J Glaucoma. 2006;16:14-19.
Endocyclophotocoagulation (ECP)and Cataract Surgery
•ECP uses laser probe with a camera
• Laser energy applied to ciliary body; shrinks the tissue
•Reduction of aqueous humor production and overall decreases the intraocular pressure

How To Choose Which Procedure?
• Based on Stage and Severity• Moderate to advanced cases – Trabectome
• Early to Moderate – iStent or Trabectome
• ? multiple iStents off label
• iStent inject shows promise
Post-operative Cataract IOP Spikes in Glaucoma Patients
•Adequate control prior to surgery• Additional drops• SLT prior
•Consideration of combined glaucoma and cataract procedures
•Aggressive treatment peri-operatively• Diamox at the end of the case, early post-op
•Closer follow-up post-operatively

Glaucoma Surgical Pearls
•Advances in technology have allowed for many good options for our cataract and glaucoma patients
•When considering cataract surgery in patient with glaucoma, a thorough assessment first of the stage and status of glaucoma is imperative
•Visual fields should be obtained PRIOR to cataract surgery
• Establish glaucoma comanagement protocols so everyone is on the same page.
