LEON RODRIGUEZ, Yereyni et al. Meesmann corneal dystrophy in a patient with hexagonal keratotomy. Rev Cubana Oftalmol [online]. 2020, vol.33, n.1  Epub June 17, 2020. ISSN 1561-3070.

Corneal dystrophies are a group of hereditary diseases often bilateral and symmetrical which progress slowly and without any relationship to environmental or systemic factors. A case is presented of a white 45-year-old female patient referred to the Cornea Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology, who reported a foreign body sensation, light sensitivity and poor vision in both eyes, as well as a history of hexagonal keratotomy from approximately 20 years before. Slit lamp examination revealed numerous punctiform lesions in the form of clear blister-like vesicles distributed paracentrally and slightly sparing the center, with transparent cornea spaces between them and better visibility of the lesions under retroillumination. Confocal microscopy showed round or oval cystic and hyporeflective structures in the right eye, whereas the left eye exhibited diffuse hyperreflective images in the basal corneal epithelium. Tortuous corneal nerves of a fragmented appearance were detected in both eyes. A Meesmann dystrophy diagnosis was considered and superficial keratectomy was performed, with which the patient's symptoms were relieved.

Keywords : Meesmann corneal dystrophy; hereditary diseases; hexagonal keratotomy.
