In view of this, the more accurate designation of the disease is possibly not dystrophy but corneal degeneration.The main pathological feature of the disease is thickened, multilaminar and disfigured basement membrane of corneal epithelium. The change in the structure affects the epithelium, some cells of which may become entrapped in the rugged membrane and fail to migrate to the surface where they should undergo desquamation. Treatment
Phototherapeutic keratectomy (PTK) done by an ophthalmologist can restore and preserve useful visual function for a significant period of time in patients with anterior corneal dystrophies including EBMD. See also
Corneal dystrophy

The diagnosis is established by sequencing the TYROBP and TREM2 genes. Differential diagnosis
Frontotemporal dementia

Investigations
X rays show the presence of bone cysts and osteoporosis. CT or MRI of the brain show loss of tissue in the frontotemporal lobes of the brain. Calcification of the basal ganglia is common. EEG is typically normal initially but diffuse slowing and irritative activity later. Treatment
There is no specific treatment for this condition. Management is supportive. Epidemiology
This condition is considered to be rare, with ~200 cases described in the literature. The estimated population prevalence is 2.0 x 10−6 in Finns. History
This condition was first described in 1973. == References ==
