ABSTRACT

Introduction: keratoglobus is an extremely rare, bilateral disease that affects patients of both sexes and different ethnic groups. It is characterized by a corneal thinning, without inflammation, diffuse, from limbus to limbus. Due to the refractive defects and corneal fragility it causes, its early diagnosis is important.
Objective: to describe the clinical characteristics of a patient with keratoglobus, its diagnosis and therapeutic options.
Case presentation: a seven-year-old male patient with crystal-corrected myopia. He went to the cornea consultation for presenting progressive decrease in visual acuity. Biomicroscopy of the anterior segment showed central corneal thinning to the middle periphery, generalized corneal protrusion, and deep anterior chambers. The corneal topography revealed elevated keratometric values over the entire surface, mainly in the central area. By pachymetry, a slight corneal thinning was observed. The ophthalmological manifestations affected both eyes, more accentuated in the left. The optical problem was corrected with gas permeable contact lenses and the patient was followed up at the cornea consultation.
Conclusions: the management of the keratoglobus is difficult at times, due to the refractive defects it induces and the corneal fragility with serious consequences such as ocular perforation and amblyopia. In the case of this patient, the disease was not associated with autosomal recessive inherited syndromes. The scientific contribution of this work lies in the detailed description of the characteristics of the keratoglobus, its diagnosis and the most advantageous therapeutic options for the patient.
