1 Retinal Disease: What the Periphery Holds Jeffry D. Gerson, O.D., F.A.A.O. Disclosure I have been on advisory boards/a consultant to/received honoraria from/ or been on speakers bureau list of the following: Allergan, Alcon, Arctic Dx, Bausch & Lomb, Freedom Meditech, Kemin, Maculogix, Optos, Optovue,Thrombogenix, VSP, ZeaVision

2 How do we see it? I love technology, but Don t forget about clinical exam 20D Slit lamp w lens Scleral depression Consider reclining What is the periphery? What is this in real life and does it matter? How much is going on here? Any Concern? Not much until..

3 The Importance of the Periphery Increasing our Clinical Evidence What does you? this mean to What do you think 44yo healthy Used to have pre-diabetes but cured w lifestyle modifications MD not concerned Now what do you want to know? In office RBG 463

4 In office A1c: >13 Unable to go to PCP today or tomorrow due work schedule Went to PCP 2 days later and started on Janumet I always try to f/u on this type of pt 3 months later. Came in for retinal f/u Retina unchanged Now on 2 meds for T2DM w dramatically changed outlook on disease EYE EXAM MADE THE DIFFERENCE!

5 If you don t think DM is a problem Not only can we find the disease early We can and have to know who is at greatest risk of vision loss We can and have to identify those more at risk of CV Dz and stroke Sick eyes are in sick patients.and sick eyes aren t always sick in the macula Diabetic Retinopathy ETDRS 7 fields vs UWF

6 DR in the periphery To properly grade DR, you need to see the periphery Up to 10% of pts will have more severe DR when periphery considered vs standard 7-field photography Temporal was most important field Can periphery predict worsening? Outcome: 2 step progression or to PDR Primary peripheral lesions (PPLs) = 3.2x risk of progression 4.7x risk to go to PDR(25%! Of PPL to PDR!!) Independent of duration, A1c, age, gender, type or baseline severity

7 More areas of PPL = more likely to progress Is DME a macular disease? Or is it a macular manifestation of peripheral non-perfusion/pathology? Chronic vs acute The same thing is potentially happening in periphery as as posterior pole Could UWF FA help determine tx needed? Does UWF FA offer value Proof of concept study shows can do less PRP and adjunctive anti-vegf as Tx for poor perfusion to decrease need for injections

8 Could less do more?? Is total PRP needed??? Diabetic Retinopathy Severity and Peripheral Lesions Are Associated with Nonperfusion on Ultra widefield Angiography The presence of peripheral lesions is associated with increased non-perfusion area and nonperfusion index These findings were not correlated with macular edema or visual acuity and remained significant after adjusting for DR severity and diabetes duration. The data from our current study provide UWF angiographic evidence to support this hypothesis further and the long-held observation that nonperfusion in DR begins in the midperipheral retina and ischemia, thus accounting for the increased risk of progression. This approach [color ETDRS photos] generally remains the current standard of care in the management of DR. However, substantial advances in eye and medical care have improved visual and anatomic outcomes for many patients with diabetes and have shifted the focus from intervening only at advanced stages of disease to diagnosing and managing earlier stages of DR to potentially slow progression or prevent DR development. The faces of DR..

9 When it goes bad Bottom line of periphery and DR..Accumulating evidence suggests that UWF imaging identifies findings in the retinal periphery that may substantially improve rates of DR detection, better characterize DR severity and more accurately define risk of DR progression.. may support a need to redefine our current DR severitly classification systems to inforporate the new findings and thus improve the

10 ability to predict natural history of DR and guide therapeutic interventions Sun JK and Aiello LP in JAMA Ophthalmology 12/2015 Retinal Breaks Flap or Horseshoe tear Operculated hole Atrophic hole Macular hole Dialysis Giant retinal tear Retinal Holes Can occur anywhere Generally no treatment, unless symptomatic Rarely progresss to RD

11 Pigmentation sign of chronicity PVD protective Retinal Tears Up to 15% of symptomatic PVD will develop tear **What do you do about symptomatic tear? Refer for treatment Tear Treatment Symptomatic tears require laser treatment Before and after Why treat symptomatic

12 Approx 50% untreated will develop RD Approx 5% treated still develop RD Retinal Detachments 2 day history of inferior blind spot 20/30 vision Superior tear Macula on or off? Intervention? 1mo after surgery, 20/25 Superior RD with single break 25 year old male with no symptoms, superior break, 20/20 vision and clear lens Treatment options?? Principles of treatment

13 Retinal coagulation Scleral buckle Vitrectomy Pneumatic retinopexy Pneumatic Retinopexy First introduced in late 1980 s Indications: Superior 8 clock hours of retina with limited break(s) covering 1 clock hour Principle: Gas bouyant upward--tension closes break--rpe pump clears SRF---Laser to seal around tear Similar success to scleral buckle Importance of positioning What s This???? RD with tear at 930 OD Gas Injected day before to tamponade Returned next (day of photo) to

14 receive successful laser R.D. cont. Superior temporal RD Pseudophakic Multiple breaks Debris in vitreous from inflammation Treatment? Primary Vitrectomy Better ineroperative sight of peripheral tears Controlled removal of vitreous Focused endo-laser Very low occurrence of PVR Allows for internal drainage Air/Fluid/Gas exchange for tamponade Excellent outcomes 25g Vitrectomy Inferior Detachment

15 Healthy 35yo male 20/25 vision with recent onset of flashes and superior curtain Clear Lens Diagnosis?? Dx: Inferior Detachment with macula on Retinal Detachment Immediate intervention needed since macula on with good vision Cryotherapy applied at time of surgery to seal retinal break With bullous RD s, drainage performed Scleral Buckle First performed in 1951 Traction pulls along downslope of buckle to create

16 radial force Change in eye contour creates new tangential force to flatten retina Different materials can be used for buckle Buckle minimally visible externally normally Potential complications PVR Buckle related Scleral Buckle Unable to use gas tamponde with inferior break Scleral buckle surgery gold standard SB alone as effective as SB +PPV in cases of undetected breaks 1 Yellow area is scar cryotherapy from

17 What s this? Scleral Buckle extrusion Can cause diplopia, motility problems, changes to retina appearance, endophthalmitis Treatment: removal of buckle, culture, antibiotic treatment To Treat or Not to Treat Indications for treatment Horse-shoe tear almost always Dialysis almost always Operculated holes sometimes Atrophic holes rarely Lattice no holes rarely Retinal Detachment Macula On Emergent

18 Macla Off Not emergent Lattice Degeneration No treatment needed if assymptomatic Prophylactic laser No definitive proof to benefit Found in 7-10% of people Approx 1% of Lattice patients develop RD Approx 2% if Lattice with holes Why not treat all lattice? 20-30% of eyes with RD have Lattice Degen. 89% of RD s from affected eyes occur in areas of normal peripheral retina So How can you treat if you don t know where RD will occur Eyes with risk factors don t seem to have lower incidence of RD if treated

19 2-4% of treated eyes still have RD 1 Prophylactic laser did not prevent tear or RD in fellow eyes if no PVD present at time of tx: 94% still developed tears, 76% developed RD 2 True science teaches us to doubt, and in ignorance to refrain Claude Bernard Can your retina get a concussion?

20 Where do you find AMD??? Mild macular drusen, with more impressive peripheral changes Dry AMD: Is it active AMD Reykjavik Eye Study A Population-Based Ultra-Widefield Digital Image Grading Study for Age-Related Macular Degeneration Like Lesions at the Peripheral Retina (Reykjavik study)

21 570 subjects with AMD at 12 year follow-up Reykjavik Eye Study color and AF optomap imaging 13.6% had AMD-like changes in the macula alone 10.1% had changes in the periphery alone 57.4% had changes in both the periphery and macula Phenotyping the retinal periphery using the categories defined by the International Classification (75 degrees) confirmed the presence of wide-ranging AMD-like pathologic changes even in those without central sight-threatening macular disease. Based on our observations, we propose here new, reliably identifiable grading categories that may be more suited for population-based UWFI. More recent literature on FAF and AMD

22 3 distinct FAF patterns identified Granular, Mottled and Nummular 90% concordance between eyes More FAF in neovasc AMD vs dry vs normal 86% vs 73% vs 18% OR w wet AMD: 12.7 and Dry: 6.2 vs normal Older age and female also associated w more FAF Associations found between: Granular FAF and peripheral drusen Mottled FAF and RPE depigmentation FAF examples A: Peripheral drusen B. Granular FAF C. RPE atrophy D. Nummular FAF

23 E. Periph RPE depig and finde drusen F. Mottled FAF at arrow, and fine FAF at drusen FAF from AREDS2 OPERA: Optos Peripheral Retina (study within AREDS2) Looked for AF abnormalities in 3 zones: central, to vortex, and outside vortex Percentage w abnormalities by zone: 94/83/50% Some difference between superior and inferior periphery, but not significant Abnormalities in both advanced and non-advanced eyes

24 So what really is AMD? A generalized retinal degeneration (present throughout the retina, especially in the periphery) that is visually significant due to changes in the retina How does Optomap AF compare Comparison of Optomap AF to HRA FAF in CSCR. Shin et al. Graefes 12/15.

25 OAF more effective than HRA in identifying area of Serous RD and also areas of mild outer retinal damage Since better at identifying margins, easier to detect changes over time OAF correlated well to not only anatomic changes, but also visual changes What does RP really look like? RP: 20/20- vision OU: impressive FAF! Another RP: 20/25-,

26 symptomatic Debbie a patient for over 10yrs Vision approximately 20/100 and stable for years Always wondering if vision will get worse Some difficulties w job, but nobody at workplace knows of visual difficulties Drives w Bioptic and has for years Stargardt s Dystrophy Does Plaquenil toxicity always start in macula? Especially in Asians, Pericentral presentation may be initial sign

27 Pericentral only in Asians in approx. 12% 50% of Asians w toxicity, had at least some pericentral (vs 2% in Caucasians) By the way, how common is toxicity: 1%/2%/20% at 5/10/20 yrs So, does the periphery matter? Peripheral retinal examination matters for not only peripheral only pathology, but also things that are thought of as macular only. Macular disease is often present in the periphery

28 The periphery may be the first sign of disease Comparison from 1 year to the next will show change over time Thank You Jeffry D. Gerson, O.D., F.A.A.O. jgerson@hotmail.com
