Transcript of Macular hole vs. Pseudo-hole

Case -72 yo Caucasian male
-referred for cataract eval
-Pt has noticed reduced vision over the last year;
esp. the last 6 wks; OS > OD
-Difficulty seeing small print
-Halos around car lights
-(+) Floaters / (-) Flashes Ocular Hx
-K burns secondary to welding
-Multiple K FB's removed
-Bilateral blepharoplasty Demographic and Complaints Meds and Allergies -Vitamins
-PCN and butazolidin VA's and Chairskills +0.75 -2.00 x103 20/25-
+0.25 -0.75 x074 20/50
-BAT VA's: 20/400+
-CVF: Full OU
-Pupils: PERRLA, (-) APD OU
-Amsler Grid: Central Blur OS
Ant Seg Exam -IOP: 13 mm Hg
12 mm Hg
-Adnexa: Clr OU
-Orbits: Nrml OU
-Conj: Quiet OU
-Cornea: Clear OU
-Ant Chamber: D & Q OU DFE -Lens: 2+ NS, 1+ cort
2+ NS, 2+ cort
-Vitreous: PVD OU
-ON: .2 R; Distinct margins
.2 R; Distinct margins
-Macula: Few Drusen
Hole vs. Pseudohole
-Vessels: Normal OU
-Periph: (-) H, T, D OU OCT OS Referral to Ret. Spec. Differentials: -epiretinal macular membranes
-pseudomacular holes
-lamellar macular holes
-macular cysts
-cystoid macular edema
-adult vitelliform degeneration -Involves the detachment of
the inner macular layers from
the underlying outer retinal layers
-Usually well circumscribed red lesion on DFE
-Detection of early lamellar holes
is difficult
-One study found only 28% of LMH's
are diagnosed clinically s OCT
-VAs often still good bc PR's still intact
(Chen, Jaeger) Lamellar hole Macular Cysts
-Often associated with ret dystrophies
-Tissue loss secondary to disruption of retinal architecture in the macular region
-IVFA shows little leakage (vascular leakage
plays small role)
-CAI's may be useful for treatment
CME -Fluid from ret capillaries collects in inner nuclear layers
-When in conjunction c sx, usually 4 to 12 wk po
-Associated with wide range of ocular and systemic conditions
-Often treated c NSAID and steroid
(Jaeger) Adult Vitelliform Degeneration -Usually occurs b/w 4th and 6th
decades of life
-VA's typically 20/30 to 20/60
-Clinical appearance of bilateral yellow subretinal
lesions with central pigment spot at fovea
(Jaeger) Macular Pseudohole -ERM contracting can give appearance
of macular hole
-OCT demonstrates steepened foveal pit
c full-thickness retinal tissue at the base
(Jaeger, Schuman) -IVFA was performed
-Determined to be a stage 2
full-thickness macular hole
-R/B of macular hole repair
were discussed and pt
opted to go ahead with surgery Macular Holes Overview -Can be associated c myopia or trauma
-Most are idiopathic
-Often go undetected by pt in cases
of unilateral macular hole
-Vision usually worsens over weeks
and months until it stabalizes around
20/200 to 20/800 if left untreated
-Female predilection
-7th Decade
(Theng) Stages -Stage 1

-Stage 2

-Stage 3

-Stage 4 -Foveal depression either reduced or absent
-Yellow ring or spot is present
-No vitreomacular separation
-Metamorphopsia -Full-thickness macular hole < 400 microns in size
-Almost always progresses to stage 3 with little hope of improvement
-VA's range from 20/50 to 20/400 -Fully-developed macular hole
-> 400 microns in diameter
-Partial vitreomacular traction
-VA's range from 20/200 to 20/800
-Full thickness hole c complete separation of
the vitreous from the ON and macula
Treatment -Many surgeons recommend surgery for symptomatic pts c a stage 2,3, or 4 hole of limited duration with a VA of 20/50 or worse

-Critical component of macular hole repair is the induction of posterior vitreous detachment
(Huang) a) Engage posterior cortical
vitreous c cannula during active
Look for "fish-strike" sign.
b) Strip cortical vitreous
c) Completion of posterior vitrectomy
c vitreous cutter
d) Fluid-air exchange
e) Completion of fluid-air exchange
(Glaser) Prognosis -Good for recent onset holes;
Poor for holes > 1 yr
-Surgery has 60–95% successful
anatomical results and 73% have
improved acuity
- Studies show that improvement of 2 lines or more occurs in about 50% of pts
