Imaging of a Severe Case of Acute Hydrops in a Patient with Keratoconus Using Anterior Segment Optical Coherence Tomography

AIM To investigate the clinical and diagnostic findings of a patient with acute hydrops using anterior segment optical coherence tomography (AS-OCT). METHODS The AS-OCT findings of a 43-year-old patient with acute hydrops associated with keratoconus were examined. At the initial examination and during follow-up, evaluation of the anterior segment was performed. RESULTS The patient presented with decreased visual acuity, pain, and redness in the right eye. The symptoms, clinical presentation, and topographical findings of the right eye confirmed the diagnosis of acute corneal hydrops. Changes in the stroma and Descemet's membrane during the healing process of acute hydrops could be demonstrated by high-resolution AS-OCT. The use of contact lenses was improved at the last follow-up visit after 8 months and increased visual acuity to 20/20 with correction. CONCLUSIONS AS-OCT is a useful tool for studying the morphologic features of acute hydrops.
