Feline restrictive orbital myofibroblastic sarcoma treated with toceranib phosphate (Palladia) as adjuvant chemotherapy: A case study of one cat.

Key Clinical Message: This is the first case report of treatment with toceranib phosphate as postsurgical adjuvant chemotherapy for advanced FROMS. This reported case highlights the need for further studies on the efficacy of toceranib phosphate as adjuvant chemotherapy for FROMS.

Abstract: Feline restrictive orbital myofibroblastic sarcoma (FROMS) is a rare aggressive tumor in cats.

Outcome of 25-gauge pars plana vitrectomy via a lateral approach without proptosis of the globe: A retrospective study in 72 dogs (78 eyes).

Objective: To evaluate the postoperative visual outcome and complications of 25-gauge pars plana vitrectomy (PPV) via a lateral approach without proptosis of the globe in dogs.

Procedures: We reviewed the medical records of dogs diagnosed with giant rhegmatogenous retinal detachment (RRD) at Yokohama Animal Eye Clinic from 2016 to 2019 and treated by 25-gauge PPV. Medical records included signalment, follow-up time, etiology and duration of RRD, angle between the outermost trocar ports, immediate postoperative anatomic success rate, pre- and postoperative visual status, and postoperative complications.

Surgical removal of cataract in an Asiatic black bear (Ursus thibetanus) by phacoemulsification and aspiration.

A twenty-year-old male Asiatic black bear (Ursus thibetanus) presented at the Rakuno Gakuen University Animal Medical Center with a 10-year history of bilateral blindness and cataracts. Surgical treatment of bilateral cataracts by extracapsular lensextraction using phacoemulsification and aspiration (PEA) was performed under general anesthesia. An anterior capsulectomy was performed using micro iris scissors and micro anterior lens capsule forceps.

Corneal collagen cross-linking following superficial keratectomy as treatment for corneal endothelial cell dystrophy in dogs: Preliminary clinical study.

Objective: To describe the outcome of corneal collagen cross-linking (CXL) combined with superficial keratectomy (SK) as treatment for corneal edema due to corneal endothelial dystrophy (CED) in dogs.

Animals Studied: Four eyes of four dogs (3 Shih Tzus and 1 English Cocker Spaniel) with corneal edema due to CED were treated with SK and CXL. Two were males, and two were females.

In-body tissue-engineered collagenous connective tissue membranes (BIOSHEETs) for potential corneal stromal substitution.

There is a severe shortage of donor cornea for transplantation in many countries. Collagenous connective tissue membranes, named BIOSHEETs, grown in vivo were successfully implanted in rabbit corneal stroma for in vivo evaluation of their suitability as a corneal stromal substitute to solve this global donor shortage. BIOSHEETs were prepared by embedding silicone moulds into dorsal subcutaneous pouches in rabbits for 1 month and stored in glycerol.

Corneal squamous cell carcinoma in two dogs.

Purpose: To report two cases of corneal squamous cell carcinoma (SCC) in dogs.

Methods: Corneal tumors were resected by superficial keratectomy in two cases. Immunohistochemistry of the corneal tissues was performed using anti-p53 antibody.

Clinical evaluation of left ventricular moderator band in 12 dogs.

We retrospectively examined clinical data for 12 dogs in which echocardiography revealed the presence of left ventricular moderator bands (LMB). Physical examinations, electrocardiography and echocardiography revealed slight cardiac murmurs, increasing QRS complex and left ventricular turbulent flow (6 of the dogs), respectively. No differences were observed with respect to gender, and no specific clinical symptoms or types of dog that frequently develop this disorder were found.

The effects of a timolol maleate gel-forming solution on normotensive beagle dogs.

The effects of a timolol maleate gel-forming solution (TMGS) on intraocular pressure (IOP), blood pressure (BP), and pupil size (PS) were evaluated in normotensive dogs. TMGS was administered once daily to six normotensive beagle dogs. TMGS administration reduced IOP and PS.

[The reevaluation of categorization for ocular manifestation of sarcoidosis in the "Guidelines for Diagnosis of Ocular Sarcoidosis"].

Purpose: To increase the degree of specificity for nomenclature in the current "Guidelines for Diagnosis of Ocular Sarcoidosis" published in 1990 by the Diffuse Pulmonary Disease Research Committee of Japan.

Subjects And Methods: We reviewed the records of patients with uveitis from the Uveitis Clinic in the Department of Ophthalmology at Yokohama City University. Subjects were selected from the records of uveitis patients with histologically proven sarcoidosis (78), and others with non-sarcoidosis uveitis (81).

Flomoxef sodium and levofloxacin concentrations in aqueous humor.

Aims: We intravenously administered flomoxef sodium (FMOX) 120 minutes before cataract surgery, topically administered levofloxacin (LVFX) into the eyes four times at 30-minute intervals before surgery, and measured the aqueous humor concentrations of these agents to investigate their penetration into the aqueous humor and their efficacy in the prevention of postoperative endophthalmitis.

Methods: Sixty-eight patients who underwent cataract surgery at the Department of Ophthalmology, Yokohama City University School of Medicine, or its affiliate, Kanazawa Hospital, Yokohama, were enrolled in this study. They received one or both of the following: 1.

Experimentally induced Vogt-Koyanagi-Harada disease in two Akita dogs.

We have investigated whether a Vogt-Koyanagi-Harada (VKH)-like disease can be induced in Akita dogs by immunizing them with tyrosinase related protein 1 (TRP1), and compared the alterations induced to those of Akita dogs with a spontaneously occurring disease that resembles human VKH disease. Two Akita dogs were immunized with a peptide mixture of human TRP1. The changes in the eyes were followed by slit-lamp biomicroscopy, ophthalmoscopy, and fluorescein angiography (FA).
