Abstract
OBJECTIVE To describe the historical, clinical, and diagnostic features of small animal patients affected by cactus-induced keratoconjunctivitis and their response to therapy. ANIMALS STUDIED Three dogs and one cat. PROCEDURES Ophthalmic examination directed subsequent selected diagnostic tests in each case including light microscopy of extracted foreign bodies, in vivo confocal microscopy (IVCM), corneal histopathology, and corneal bacterial culture. Treatments consisted of foreign body surgical extraction with concurrent medical therapy (three cases), or medical therapy alone (one case). RESULTS Clinical histories obtained supported acute cactus injury in all cases. Ophthalmic abnormalities were unilateral in each case and included ulcerative keratoconjunctivitis associated with linear, microscopic conjunctival and/or corneal penetrating cactus spines, known as glochids. Light microscopy and IVCM showed glochids to be heavily barbed, consistent with the spine morphology Prickly Pear (Opuntia) cactus species. Bacterial culture yielded Proprionicimonas sp. in one case with keratomalacia. Surgical extraction of spines was challenging, and residual conjunctival and/or corneal glochids were present in all cases. Patient discomfort resolved at a median of 21 days (range 10-51 days). Vision-threatening complications were not observed in any case at the time of last follow-up examination. Epithelial downgrowth, demonstrated by IVCM and histopathology, was present in one case at 108-day follow-up. CONCLUSIONS Cactus-induced keratoconjunctivitis should be considered as a differential in regions in which Opuntia cacti are prevalent, and microscopic ocular foreign bodies are observed. Although glochids are difficult to extract, positive clinical outcomes can occur in small animal patients despite the presence of residual organic corneal foreign material.

Abstract
Background To report a case of femtosecond laser-assisted removal of an intracorneal chestnut. Case presentation A chestnut was obliquely protruding to the stroma of cornea and it was localized at the paracentral region on the left eye of a 32-year-old man. The best-corrected visual acuity (BCVA, in decimal values) was 0.6 in the injured eye. The white ulcers with feathery edges or satellite infiltrates were not observed in the lesion, and the anterior chamber was deep and quiet. Anterior segment optical coherence tomography (AS-OCT) demonstrated that the original entry path of the foreign body had been sealed, spanning a thickness of approximate 152 μm. In view of location of the intraocular chestnut at the paracentral region, femtosecond laser was applied according to the procedures of IntraLase Enabled Keratoplasty (IEK) to create an anterior lamellar flap rapidly and precisely. The lamellar flap was easily separated with a flap lifter, and the chestnut was removed entirely using a pair of forceps. In 3 days after surgery, the patient complained of mild pain and blurred vision. These symptoms were relieved after treatment with the eyedrops. At three-month follow-up, the corneal wound was healed well, and the BCVA was greatly improved to 1.2 in the left eye. A dot-like haze was observed corresponding to the scar at the site of foreign body removal. No surgical induction of corneal astigmatism was found in the corneal topography. Conclusions Without induction of a visually significant scar and corneal astigmatism, the IEK procedure of femtosecond laser is of particular interest as it provides a unique method for removal of intracorneal foreign bodies impinging on the visual axis.

Abstract
An unusual case of a penetrating grass awn in an eyelid of a dog is reported. A 6-month-old mixed breed dog was referred to the Ophthalmology Unit of the Veterinary Teaching Hospital of Camerino University for anorexia, lethargy, left monolateral ocular swelling and pain to the left eye, present from 1 month. Ophthalmic examination of the left eye showed copious and purulent discharge, and ultrasonography revealed the presence of an abscess containing a grass foreign body. The grass awn was surgically removed. Three days after surgery, the dog showed a marked improvement, with a total resolution obtained in 7 days. To the authors' knowledge, penetrating foreign bodies such as the one of this paper have never been described before in literature.

Abstract
OBJECTIVES To review clinical data on dogs that suffered a corneal and anterior segment foreign body (CASFB) trauma and to determine the risk factors for foreign body (FB) trauma and subsequent enucleation. ANIMALS STUDIED Dogs with CASFB presented to the Animal Health Trust (AHT) from January 2000 to December 2012. PROCEDURES Clinical data for CASFB cases were compared to those available for the remaining AHT ophthalmic population over the same period. The depth of the FB trauma was divided into five categories. The type of FB and method of removal were described for each category. The degree of secondary uveitis and lens involvement was graded and correlated with subsequent enucleation. RESULTS The mean age (standard deviation) of 218 identified CASFB cases was 3.96 (2.95) years. Risk factors for CASFB trauma were dogs younger than 5 years, English Springer Spaniels, Labrador Retrievers, and working dogs. Most dogs required general anesthesia for FB removal, and hypodermic needles were the most commonly used instrument. The lens was involved in some cases with a full-thickness CASFB trauma (n = 49, 45%), but most suffered a minor lens trauma (n = 37, 76%). The lens trauma and phacoclastic uveitis were managed medically in most dogs (n = 37, 76%), and phacoemulsification was only elected as initial treatment in some dogs (n = 10, 20%). Enucleation was required overall in 6% of dogs. Statistically significant associations were found between enucleation and depth of FB trauma, degree of uveitis, and severity of lens trauma (P < 0.001). CONCLUSIONS Young dogs, English Springer Spaniels, Labrador Retrievers, and working dogs had an increased risk of CASFB trauma. Risk factors for enucleation were full-thickness FB penetration, severe lens trauma, and severe uveitis.

Abstract
Objectives: To study the ocular and extra-ocular features, clinical presentation, and treatment of prickly pear glochids. Materials and Methods: This retrospective study included 23 eyes of 21 patients with ocular prickly pear spines who were seen between August and October 2011 in the outpatient ophthalmic clinic at Prince Rashid Bin Al Hassan military hospital in Jordan. Medical records of patients including age, gender, history of exposure to prickly pear plants, and ocular examination were reviewed. All glochids were localized and removed with forceps under topical anesthesia with the patient at the slit lamp. Patients were followed up after one week. Results: The mean age of patients was 37.1 years with a male to female ratio of 1.6: 1. Involvement of the right eye was seen in 61.9% patients, left eye in 28.6% patients, and bilateral involvement in 9.5% patients. Glochids were most commonly found in the upper subtarsal conjunctival space (47.6%) followed by inferior palpebral conjunctiva in 23.8% eyes. The most common complaint was eye irritation in 95.2% patients. Pain was a complaint in 57.1% patients. Superior corneal epithelial erosions or ulcer were found in 33.3% patients, inferior corneal epithelial erosions in 19.1% patients, and diffuse epithelial erosions in 9.5% patients. Glochids were found in other parts of the body in 38.1% patients. Conclusion: Although prickly pear glochid ocular surface injury is not uncommon in the region during summer, it should be considered in patient with eye pain during that period. Farmers who are in close contact with prickly pears should use protective eyeglasses and gloves.
