OBJECTIVE: To describe a nonsurgical treatment for superficial corneal epithelial inclusion cysts (CEICs) in dogs and to characterize their clinical and diagnostic features using ultrasound biomicroscopy (UBM) and optical coherence tomography (OCT).
ANIMALS: 4 client-owned dogs with superficial CEICs.
CLINICAL PRESENTATION: Complete ophthalmic examinations and diagnostic imaging using UBM and/or OCT were performed on smooth, fluctuant, painless masses protruding from vascularized corneas. For superficial CEICs, needle lancing was performed under topical anesthesia.
RESULTS: All dogs had been previously managed for keratoconjunctivitis sicca. Ultrasound biomicroscopy or OCT revealed superficial intrastromal cystic lesions surrounded by hyperechoic or hyper-reflective stroma, consistent with CEICs. All cysts were located within vascularized corneal stroma, with sufficient posterior stromal thickness and intact Descemet membrane beneath the cysts. Among 6 initially identified cysts, 1 ruptured spontaneously following trauma and was no longer detectable at reexamination. One cyst was excised by superficial keratectomy, and histopathologic examination confirmed CEIC; this cyst subsequently recurred. The remaining 4 cysts were intentionally treated by needle lancing using a 26-gauge needle under topical anesthesia. Cytologic examination of the drained material revealed predominantly extracellular matrix and epithelial cells without evidence of infection, supporting the diagnosis of CEIC. Topical anti-inflammatory agents and antibiotics were prescribed after lancing. None of the lanced cysts recurred during a follow-up period of 17 to 62 months.
CLINICAL RELEVANCE: Needle lancing may represent a safe, simple, and effective treatment option for superficial vascularized CEICs in dogs. Advanced diagnostic imaging, such as UBM/OCT, may aid in determining cyst depth and guiding treatment selection.
