Case series summary Described are 13 cats diagnosed with deep ulcerative keratitis and successfully managed medically without grafting procedures. Typical treatment involved frequent topical application of serum and antibiotics (usually a fluoroquinolone and a cephalosporin). Seven cats also received systemic antibiotics. Analgesia was achieved using various combinations of topical atropine and systemic buprenorphine, robenacoxib or corticosteroids. Six cats were hospitalized for a median (range) period of 2...

A 53-year-old female presented with keratitis (right eye) after fall of insect 10 days back. The ulcer worsened in spite of aggressive treatment with topical natamycin (5%) and amphotericin-B (0.15%) eye drops and finally perforated. Iris tissue sealed the perforation site, and ulcer healed with formation of adherent leucoma. This case represents first reported case of keratitis caused by Laetisaria arvalis and stresses on aggressive course of keratitis caused by this fungus. Importance of DNA sequencing in identification of unidentified fungal species is also highlighted...

Emodin is an anthraquinone compound derived from Rheum officinale Baill. Several reports showed that emodin had efficacy on acute pancreatitis, keratitis, myocarditis, and rheumatoid arthritis. However, the potency of emodin on ulcerative colitis(UC) remains unclear. In this study, we investigated the effect of emodin on dextran sodium sulfate (DSS)-induced ulcerative colitis in mice. Our results showed that emodin significantly alleviated the symptoms of DSS-induced UC in mice, involving prevented the loss of body weight and colon shortening, decreased the disease activity index (DAI), intestinal damages and the count of white blood cells (WBC) in peripheral blood...

An adult great-horned owl (Bubo virginianus; GHOW) presented with a history of recurrent corneal ulceration of the right eye (OD). Findings included ulcerative superficial keratitis, proliferative conjunctivitis, and iris pigmentary changes. The ulcer was initially nonresponsive to medical therapy, but showed rapid and appropriate healing following diamond burr debridement. Proliferative conjunctivitis markedly improved following topical antiviral therapy with cidofovir 1%, interferon alpha 2B ophthalmic solutions, and oral l-lysine...

Chestnut burrs, the thorny encapsulation of chestnut fruit, can sometimes cause corneal injuries and ulceration, with poor prognoses. We report a case of corneal perforation and damaged anterior lens capsule due to a chestnut burr, using anterior segment optical coherence tomography (AS-OCT). A 67-year-old woman with a chestnut burr injury in her right eye was referred to our hospital. Her right best-corrected visual acuity (BCVA) was 0.8. Slit-lamp examination and AS-OCT showed perforation involving the endothelial layer at the center of the cornea...

Pathogenic Acanthamoeba species often cause infection known as Acanthamoeba keratitis among people who use contact lenses. It is a type of infection that can result in corneal ulceration, visual loss or even blindness, if not treated. There are various therapeutic options available in the treatment of Acanthamoeba infections but they are usually tough treatments with limited efficacy. For instance, hydrogen peroxide (H2 O2 ) is a commonly used contact lens disinfectant which is effective against Acanthamoeba but it is toxic to the cornea...

An 11-year-old female patient presented with diminution of vision in both the eyes for the last 4 days. She had redness, watering and photophobia for the past 11 days. Slit lamp examination revealed multiple disc-shaped corneal stromal infiltrates with an overlying epithelial defect and hypopyon in both the eyes. A provisional diagnosis of infective keratitis was made. The patient was started on empirical antimicrobial therapy. However, no improvement was noted over the next 72 hours. Microbiological examination of the corneal scraping from both the eyes was negative...

PURPOSE: Here, we report risk factors associated with outcome in severe bacterial keratitis (BK), fungal keratitis (FK), and Acanthamoeba keratitis (AK) in India. METHODS: Prospective observational cohort study conducted in Aravind Eye Hospital, India. Adults presenting with severe microbial keratitis (MK) were enrolled (size ≥3 mm) and followed to 21 days post-enrolment. Ulcer clinical features were recorded at presentation. Outcomes by final visit were classified as good (completely healed or reduced infiltrate size) or poor (enlarged infiltrate size, perforated, or surgery performed)...

Objectives To determine the patterns, predictors and overall impact of ocular manifestations of rheumatoid arthritis (RA) on the health-related quality of life and disability index. METHODS: A total of 50 Nigerian patients with RA were studied. Full ocular evaluation was done to determine the presence of each defined ocular manifestation of RA. All patients completed the Medical Outcome Study 36-Item Short Form Health Survey (SF-36) and the Health Assessment Questionnaire-Disability Index (HAQ-DI) questionnaires...

SIGNIFICANCE: Lacrimal punctal plugs may prevent the teratogenicity of the treatment used in infectious keratitis. Its use should be strongly considered in these cases. PURPOSE: We present the case of a 7-week pregnant patient with Acanthamoeba keratitis. CASE REPORT: The patient was a contact lens user with photophobia, redness, and intense pain in the right eye that started 2 weeks earlier. Corrected visual acuity was 20/63 (0.5 logMAR)...

BACKGROUND: Pythium insidiosum is a parafungus that causes keratitis resembling fungal keratitis. This study compares outcome in a large cohort of patients with P insidiosum keratitis treated with antifungal drugs, to a pilot group treated with antibacterial antibiotics. METHODS: Between January 2014 and December 2016, 114 patients with culture positive P insidiosum keratitis were included in the study. A subset of culture isolates was tested in vitro for response to nine antibacterial antibiotics by disc diffusion and E test...

OBJECTIVE: The study objective was to develop a method for surgical treatment of advanced purulent corneal ulcer in the setting of neuroparalytic keratitis developed after acoustic neuroma removal and strokes. MATERIAL AND METHODS: The study included 12 patients (13 eyes). All patients underwent single-step keratoplasty, conjunctival autografting, and partial permanent tarsorrhaphy. RESULTS: The eye as an organ was spared in 100% of cases; vision was spared in 50% of cases and improved, from 0...

RATIONALE: Sjögren syndrome (SS) is frequently associated with ulcerative keratitis, which is difficult to treat due to lacrimal tear deficiency and inflammation of the ocular surface. PATIENT CONCERNS: We report the successful additive effect of a matrix regenerating agent (RGTA, Cacicol) in SS patients with severe superficial ulcerative keratitis resistant to conventional therapy. DIAGNOSES: Retrospective, noncomparative case series of patients with primary or secondary SS associated with chronic diffuse keratitis...

BACKGROUND: Mortality episodes have affected young-of-year smallmouth bass (Micropterus dolomieu) in several river systems in Pennsylvania since 2005. A series of laboratory experiments were performed to determine the potential role of largemouth bass virus (Ranavirus, Iridoviridae) in causing these events. RESULTS: Juvenile smallmouth bass experimentally infected with the largemouth bass virus exhibited internal and external clinical signs and mortality consistent with those observed during die-offs...
