Fuchs' Dystrophy

Patient MRN: 91013353
26 year old Asian Female

Patient History:

Cataract Surgery in both eyes; aphakic lens OD/OS
-Strabismus
-ocular hypertension

Findings:

OD:
IOP:17
Pachymetry:818
Keratometry:45.60
VA:20/80-1
Cornea:diffuse bulbus keratopathy with stromal folds

Differential Diagnosis

Corneal Edema: Due to guttata seen in left eye, pachymetry result of 658 is slightly higher than average in left eye but very high in the right eye suggesting significant corneal swelling.

Cataract Surgery: Could have reduced endothelial cell density resulting in guttata. Could have had an effect in VA.

Keratitis: Calcification on iris could have let to reduce VA with correction, redness, and discomfort.

Ocular hypertension: might be affecting VA, could have been worsening corneal edema in combination with cataract surgery.

Low Endothelel cell density: Patient might have had per-operative low endothelial cell density which have caused manifestations seen now after surgery which reduced the cell density.

Current Research:

"Outcomes of cataract surgery in eyes with a low corneal endothelial cell density."
-Patients who underwent cataract surgery with low endothelial cell density(ECD) were evaluated.
Results: Out of the 63 eyes tested, 20 eyes had preoperative Fuchs' Dystrophy.Mean ECD after surgery was 611-693 and cell loss was at 11.5%. Regardless, VA improved from .59 to .32 (logMAR) indicating that vision improvement is possible even for those who have a low ECD.

"Visual acuity and contrast sensitivity following Descemet stripping automated endothelial keratoplasty."
-Patients with Fuchs' Dystrophy (128) underwent DSAEK which strips away and replaces the thickened endothelial basement membrane and their post-operative results were observed.
Results: Significant improvement in VA were seen among patients (majority Asian and women) at 12 months along with improved contrast sensitivity at 6 months indicating the benefits of this treatment.

Definition:

What is it: Corneal swelling that can cause discomfort, cloudiness, and glare due to inadequate pumping of fluid out of the cornea by the endothelial cells that are slowly dying off.

Treatment

Eye Drop/Ointments

Soft contact lenses

Corneal Transplant

Replacement of inner corneal layer by:
Descemet stripping endothelial keratoplasty (DSEK) and Descemet membrane endothelial keratoplasty (DMEK).

Symptoms:

Corneal thickening

Corneal swelling

Endothelial guttata

Pain and discomfort

Blurry/light sensitive vision

Painful blisters on corneal surface

Cloudiness, haze, glare on cornea

OS:
IOP: 16
Pachymetry:658
Keratometry:41.80
VA:20/70
Cornea:Endothelial guttata, corneal edema
