  • A 7-month-old intact male Maltese dog was presented with a 1.5-month history of glaucoma in the right eye (OD). Ophthalmic examinations revealed a corneal perforation with iris entrapment, corneal edema and neovascularization, and buphthalmos OD. Intraocular pressures were 33 mmHg OD and 19 mmHg in left eye (OS). The right eye was diagnosed with chronic glaucoma and corneal perforation with iris entrapment. Now that the eye was blind, implantation of intraocular silicone prosthesis (ISP) and conjunctival flap were elected to salvage the globe. The corneal perforation healed with the conjunctival pedicle flap and the cornea accommodated the ISP properly. A satisfactory cosmetic result was achieved without complications in the 15 months following the procedure. Therefore, this case report indicates the combined an ISP and a conjunctival flap would be an alternative for the treatment of glaucoma associated with corneal perforation in dogs.

  • An 8-year-old male dog weighing 7.9 kg was referred to us for evaluation of exophthalmos and corneal edema of the left eye, on which cataract surgery had been performed 3 years prior. On ophthalmic examination, the left eye showed an extremely high intraocular pressure (47 mmHg), with no menace response, dazzle reflex, or pupillary light reflex. The dog was treated with systemic and topical glaucoma medications. After treatment, corneal edema decreased but IOP did not return to within acceptable limits. Seventeen months later, the dog presented with hyphema, episcleral congestion, and corneal edema attributable to accidental trauma. The owner wished to maintain an attractive ocular appearance, and an intraocular silicone prosthesis (ISP) was thus inserted after the evisceration. Three months postoperatively, a corneal ulcer was detected, but this resolved successfully after prescription of appropriate medication. One year after surgery, no complications related to surgery were evident.

Evisceration and Intrascleral Silicone Ball Prosthesis with Penetrating Keratoplasty on Perforated Corneal Ulcer Secondary to KCS in a Shih Tzu Dog (개의 건성각결막염에 의한 각막천공을 안구내용물적출술과 실리콘볼 삽입 후 각막이식을 적용하여 치료한 증례)

  • When severely large corneal perforation occurs, penetrating keratoplasty is a treatment of choice alternative to enucleation. A twelve-year-old male Shih Tzu was referred with perforated corneal ulcer secondary to keratoconjunctivitis sicca (KCS). Perforated cornea was directly sutured using 10-0 non-absorbable suture material, and rotational conjunctival flap was performed. However, re-perforation of cornea by wound dehiscence was observed at 1 month after operation. The yellowish lens escaped outside the orbit during corneal re-perforation, the diagnosis was re-perforated corneal ulcer, moderate corneal edema, moderate KCS (STT; 6 mm) and endophthalmitis caused by escaped lens outside orbit. Accordingly, penetrating keratoplasty (PK) and evisceration through corneal recipient site and intrascleral silicone ball prosthesis were carried out as the planned treatment, and resulted in good cosmetic improvement compared to enucliation. However, exposure of silicone ball occurred at the 9 months after the surgery due to the irritation of implant, thus enucleation was performed. In perforated large corneal ulcer with severe intraocular damage, evisceration with silicone ball insertion with PK would be alternative treatment choice to improve the cosmetic appearance.

  • An eight-year-old Shih-Tzu dog was referred to Kyungpook National University Veterinary Medical Teaching Hospital because of severe glaucoma and exophthalmos. The symptoms included severe buphthalmos, conjunctival hyperemia, focal dried cornea and discomfort in the affected eye. Although enucleation was considered as a potential intervention measure in light of the severity of symptoms, it was possible to save the globe and relieve symptoms through evisceration, intraocular prosthesis implantation, and lateral canthoplasty. Our experience with this case suggests that symptomatic salvage therapy, rather than enucleation, is an appropriate approach for resolution of exopthalmos and other complications associated with glaucoma surgery.
