One single family of corneal lattice dystrophy was examined and interviewed to elucidate the
variety of clinical manifestations, factors associated with visual impairment, and the impact on the
patient's quality of life.
Forty-three out of 88 family members (48.9%) were affected. The inheritance pattern was
autosomal dominant. Corneal haze grading from 1 to 4 was 5.3 per cent, 26.3 per cent, 43.4 per cent, and
25 per cent respectively. Surface irregularity grading from 1 to 4 was 18.4 per cent, 39.5 per cent, 32.9
per cent, and 9.2 per cent respectively. Forty-five per cent of the patients had VA::; 20/200. Corneal
haziness, irregularity, corneal erosion and disease duration were significantly related to visual impair-
ment (p
<
0.05). This disturbed the patient's activities such as reading (79.1 %), working (62.8%) and
daily life (69.8%).
Corneal lattice dystrophy within the same family may present with different manifestations
depending on the severity and duration of the disease and might be misdiagnosed. Inadequate know-
ledge among patients was susceptible to the high prevalence of the disease leading to impaired quality
of life.
