Early bacterial keratitis after presbyopic LASIK.

Purpose: To report an unusual case of infectious keratitis that occurred after presbyopic laser-assisted in situ keratomileusis (LASIK).

Methods: A 57-year-old woman presented with decreased visual acuity and pain in her right eye 2 days after a bilateral presbyopic LASIK procedure. Slit-lamp examination showed a large corneal infiltrate surrounded by marked corneal inflammation.

In vivo confocal microscopy in fungal keratitis.

Background: Fungal keratitis is a major blinding eye disease found throughout the world, particularly in developing countries. Given the recent increase in Fusarium keratitis infections in contact lens wearers owing to contact lens solutions, a warning was recently issued by the Food and Drug Administration, making it a public health concern in developed countries.

Objective: To show the advantages of in vivo confocal microscopy imaging using the Heidelberg Retina Tomograph II-Rostock Cornea Module (HRTII-RCM) in the early diagnosis of fungal keratitis.

Heidelberg retina tomograph II findings of Acanthamoeba keratitis.

Purpose: Heidelberg retina tomograph II (HRTII) examination was performed with cornea module in one patient with Acanthamoeba keratitis (AK) to provide images detailing characteristic findings of the disease.

Methods: A 34-year-old woman presented with clinical signs and symptoms of AK. HRTII with cornea module was performed and the patient underwent laboratory investigations.

Decreased corneal sensitivity in patients with dry eye.

Purpose: To explore changes in corneal sensitivity that develop in patients with dry eye and the relationship between sensibility and severity of the dry eye disease.

Methods: Experiments were performed in 44 patients with dry eye and 42 healthy individuals. Corneal sensitivity was measured with the Belmonte noncontact gas esthesiometer.

Early bacterial keratitis after laser-assisted subepithelial keratectomy.

We report a case of bacterial keratitis that occurred after laser-assisted subepithelial keratectomy. The patient presented with a decrease in visual acuity and pain 2 days after the procedure. Culture was positive for Staphylococcus haemolyticus.

Corneal keloid: clinical, ultrasonographic, and ultrastructural characteristics.

A 70-year-old man was referred to us with a 2-year, progressive, painless decrease in visual acuity in the right eye. Ocular history included extraction of a traumatic cataract with a transclerally fixated posterior chamber intraocular lens. Slitlamp examination showed a raised, white, vascularized mass covering the cornea.

Bacterial keratitis: predisposing factors, clinical and microbiological review of 300 cases.

Aim: To identify predisposing factors and to define clinical and microbiological characteristics of bacterial keratitis in current practice.

Methods: A retrospective analysis of the hospital records of patients presenting with bacterial keratitis and treated at the Quinze-Vingts National Center of Ophthalmology, Paris, France, was performed during a 20 month period. A bacterial keratitis was defined as a suppurative corneal infiltrate and overlying epithelial defect associated with presence of bacteria on corneal scraping and/or that was cured with antibiotic therapy.

Late bacterial keratitis after implantation of intrastromal corneal ring segments.

We report a case of bacterial keratitis that occurred after implantation of intrastromal corneal ring segments (Intacs). The patient presented with decreased vision, inflammation, and stromal infiltrates localized at the extremity of an Intacs channel 3 months after surgery. Culture were positive for Clostridium perfringens and Staphylococcus epidermidis.

Candida parapsilosis keratitis.

Purpose: To present clinical, microbiologic, and histopathologic features of keratitis due to Candida parapsilosis.

Methods: Clinicomicrobiologic evaluation of four patients (four eyes) with culture-proven C. parapsilosis keratitis.
