Acute Corneal Hydrops in Patient With Post-LASIK Ectaisa: Role of Anterior Segment Optical Coherence Tomography
Purpose
To describe a case of acute corneal hydrops in a case of Post LASIK Ectasia. Differential diagnosis, role of imaging and management options of this rare entity will be discussed.
Methods
A rare Case Report describing role if imaging in diagnosis and management of acute corneal hydrops in a middle aged male.
Results
A 58 years old subject presented with sudden onset decrease in vision, 14 years following LASIK for a refractive error of -3.0 Dioptres.Slit lamp examination showed large fluid pocket with a well defined zone of central corneal edema leading to a clinical diagnosis of interface fluid syndrome.. ASOCT showed a slit like path connecting the posterior stroma to the interface, thereby confirming the diagnosis of acute corneal hydrops. Few months after failed C3F8 Descmetopexy, optical penetrating keratoplasty was done. Histopathology confirmed the prescence of a stromal cleft connecting the site of descemet's break to the interface beneath the LASIK flap.
Conclusion
This is the first case report describing occurence of Hydrops in the 6th decade of life, more than a decade after LASIK. This report highlights the role of imaging in diagnosis, poor outcome of descmetopexy in cases with large descmet's breaks, and expected good visual outcomes following penetrating keratoplasty in corneal hydrops.
