• Elevated IOP is primarily caused by increased aqueous outflow resistance at the trabecular meshwork

Nitric Oxide in the Eye

• NO increases trabecular outflow by inhibiting actin‐myosin interaction, which relaxes TM

• NO causes vasodilation and increased blood flow to the optic nerve

• Evidence exists of dysregulation of the NO pathway in glaucoma

Vyzulta (Bausch and Lomb) 

• Latanoprostene bunod (LBN) 0.024%

• Nitric oxide donating prostaglandin F2 alpha analog– Latanoprostene is metabolized in situ to latanoprost acid– Bunod modification (butanediol mononitrate) is a nitric oxide donator

• NOT a new class of medication nor a fixed combination –PGA with DUAL MECHANISM OF ACTION

• Additive effect to lower IOP by:– Increasing uveoscleral outflow – latanoprost– Increasing trabecular outflow – NO

• Also? ‐ Speculative– NO dilates blood vessels – increase blood flow to ONH?– Neuroprotection?

IOP Fluctuation Matters

Research suggests that short‐term IOP fluctuation may be an independent risk factor for the incidence, prevalence and progression of glaucoma.

Boland MV, Quigley HA. J Glaucoma. 2007;16:406‐418. Asrani S, Zeimer R, Wilensky J, et al. J Glaucoma. 2000;9:134‐142.

Not only is an ideal mean target IOP needed, but also a target for IOP fluctuation.  Asrani S, Zeimer R, Wilensky J, et al. J Glaucoma. 2000;9:134‐142.

What is it?• The Icare® HOME tonometer is a handheld, battery operated device that measures intraocular pressure (IOP) without the need for topical anesthetic. 

• The device is intended as an adjunct for monitoring IOP of adult patients (self‐use). The HOME tonometer is designed for use at home or on the go.

Icare HOME tonometer• IOP, date, time, eye recognition 

(right/left) and measurement quality are all stored in the internal memory. 

• Data is transferred to a PC for further analysis by the prescribing physician.

• New features: positioning light, automatic eye recognition system, series or single measurements, new user interface panel.

Results of Icare Home Study

• 171 patients– 7 dropped out because of time concerns– 10 couldn’t be trained to use it– 27 couldn’t be certified based on IOP (5mm Hg difference between HOME and GAT)

• Of the other 127– 116 (91.3%) HOME and GAT agreed within 5mm Hg– Mean difference between HOME and GAT was ‐0.33mm Hg– R = 0.92

Questions???

• How many times per day and for how long should it be utilized?

• How can practitioners use it in their offices?

• As it cannot be used when the patient is supine, can it tell us anything about nighttime IOP?

Data is wirelessly transmitted from the lens to the antenna, that is applied adhesively around the eye (2)

The data is transmitted through a wire to a recorder (3) that the patient wears (4)

The data is then downloaded to the practitioners computer for analysis

Patients maintain their regular routine and wear the lens for 24 hours, capturing the most sensitive night time activity

The lens is applied just like a contact lens (1)

Why is this important?

• The data has been shown that elements of the TF curve are highly correlated to glaucoma progression

• Initiation of therapy may be effectively monitored with TF application

• Data has shown that the curve that is produced may also be indicative of glaucoma even with normal IOP (NTG)

• Healthy eyes versus diseased eyes may also be determined (screening application)

• Records changes during critical times such as sleep

Questions???

• What information is it actually giving us?

• How do we use this information?

• What will be the cost?

EAGLE Study

• Inclusion– PACG with IOP > 21– PAC with IOP > 30 (1/3 of the patients)

• Compared clear lens extraction vs. LPI

• CE performed better across all clinical (IOP) and patient‐reported outcomes (QOL, cost‐effectiveness ratio per quality‐adjusted life‐year gained) at 36 months

ZAP Study

• Compared prophylactic LPI versus no treatment in bilateral angle closure suspects to determine risk of primary angle closure

• Very low risk of AAC in eyes that don’t get LPI

• Most AAC after dilation

• Results indicate that widespread prophylactic  LPI for PACS is not indicated

LiGHT Study• Performed in the UK (National Health Service)

• Compared SLT to medicine as first‐line treatment over 36 months– N = 718

• Outcomes– HRQoL the same between groups– 74.2% of patients in the SLT group required no drops to maintain target IOP– SLT more cost‐effective

• MAJOR RECOMMENDATION: SLT should be offered as a first‐line treatment for OAG and OHT, supporting a change in clinical practice

Questions

Should we be doing 10‐2 on all of our glaucoma suspects or glaucoma patients?

Should we be doing 10‐2 on our glaucoma suspects who have ganglion cell changes in the macula?

Can we modify current visual field protocols i.e. 24‐2 so that we can easily test the central 10?

Chicken or Egg?

• Are vascular changes in glaucoma the cause of glaucoma damage or do they result from glaucoma damage?

OCT‐A and Glaucoma

• As compared to normals, glaucoma suspects and patients have– Attenuated vascular density– Enlarged FAZ– Reduced blood flow index

• Reduction in vessel density in glaucomatous eyes is found in both superficial and deep vascular plexi

• Eyes with hemifield field defects have reduced vessel density in both hemifields – is this predictive of future damage?
