Introduction. Fabry disease (FD) is a lysosomal storage disorder associated with multiple organ dysfunction which eventually leads to high morbidity and premature mortality. Ophthalmologic findings in FD are very common and have been described extensively. We describe the ophthalmologic findings of a family diagnosed with FD at Hospital de Especialidades de Puebla and establish their relationship with other phenotypic findings. Cases Presentation. A renal, cardiac, audiological, neurological, and ophthalmologic evaluation was carried out. The disease was confirmed by GLA gene sequencing. The ophthalmologic assessment was focused on the changes described in the literature, as well as the search for other anomalies possibly related to the disease. All the patients had the c.260delA (P.Glu87Glyfs*34) mutation in the GLA gene. The main ophthalmologic finding in our patients was cornea verticillata (in 100 % of the female patients). Other ophthalmologic manifestations were dry eye, retinal vessel tortuosity, ametropia, chromatic vision disorders, ocular annexes, eyelids, and conjuntiva disorders. Conclusions. Most of the assessed patients showed ophthalmologic changes, consistent with the results described in the literature. A remarkable finding in the sample was the high incidence of changes in women, in whom one would not expect the disease to be as severe because they are heterozygous. Ophthalmologic abnormalities in FD require deeper evaluation to establish their possible use as markers of disease progression and/or enzyme replacement therapy initiation due to the benefit of the non-invasive nature of ophthalmologic evaluations.
