Cavernous hemangioma of the orbit: an unusual acute presentation.

We report an unusual presentation of an orbital cavernous hemangioma in a 26-year-old female, who noted sudden redness and swelling of the left eye (LE) on waking up. At presentation, upper eyelid edema with periorbital ecchymosis and subconjunctival hemorrhage were noted in the LE. Although there was transient symptomatic relief with topical medications, blurring of vision developed in the LE.

Spectrum of bacterial keratitis at a tertiary eye care centre in India.

Aim: To report the aetiological spectrum and susceptibility patterns of bacteria isolated from patients with corneal ulceration.

Method: The microbiological data of all patients with suspected infectious corneal ulceration who presented to the ocular microbiology service at this centre between 2005 and 2012 were reviewed retrospectively.

Result: Microorganisms were recovered from 1665 (77%) of the 2170 ulcers.

Keratitis due to Chaetomium sp.

Aim. To describe keratitis due to Chaetomium sp. occurring in a 65-year-old woman who presented with a corneal ulcer with hypopyon of the right eye with a history of trauma by vegetable matter.

An outbreak of post-cataract surgery endophthalmitis caused by Pseudomonas aeruginosa.

Objective: Infectious endophthalmitis is among the most serious complications of cataract surgery. Gram-negative bacteria, including Pseudomonas aeruginosa, are responsible for less than 30% of cases; however, their rapidity of infection and virulence often results in poor visual outcome despite prompt antibiotic treatment. The purpose of this study was to investigate an outbreak of post-cataract surgery P.

Fibrinous anterior uveitis following laser in situ keratomileusis.

A 29-year-old woman who underwent laser in situ keratomileusis (LASIK) for myopic astigmatism in both eyes presented with severe pain, photophobia and decreased visual acuity in the left eye eight days after surgery. Examination revealed severe anterior uveitis with fibrinous exudates in the anterior chamber, flap edema and epithelial bullae. Laboratory investigations for uveitis were negative and the patient required systemic and intensive topical steroids with cycloplegics to control the inflammation.

Anticataractogenic effect of an extract of the oyster mushroom, Pleurotus ostreatus, in an experimental animal model.

Purpose: To evaluate the efficacy of Pleurotus ostreatus extract in preventing selenite-induced cataractogenesis.

Methods: In vitro, enucleated rat lenses, divided into one control and three experimental groups (selenite only, simultaneous selenite and extract, initial extract and subsequent selenite), underwent morphological and biochemical evaluation. The anti-cataractogenic effect was also evaluated in vivo.

Prevention of selenite-induced cataractogenesis in Wistar rats by the polyphenol, ellagic acid.

The present study sought to evaluate the efficacy of the naturally-occurring polyphenol, ellagic acid, in preventing selenite-induced cataractogenesis. In the present study, Wistar rat pups were divided into 3 groups of 15 each. Group I (normal) rats received an intraperitoneal (i.

Acetyl-L-carnitine prevents selenite-induced cataractogenesis in an experimental animal model.

Purpose: To investigate whether acetyl-L-carnitine (ALCAR) retards selenite-induced cataractogenesis in vivo.

Methods: On postpartum day 10, group I pups received intraperitoneal saline and group II and group III pups received subcutaneous sodium selenite; Group III pups also received intraperitoneal ALCAR once daily on postpartum days 9-14. Both eyes of each pup were examined up to postpartum day 30.

Comparative evaluation of optical coherence tomography in glaucomatous, ocular hypertensive and normal eyes.

Background: To correlate the findings of optical coherence tomography (OCT) evaluation of retinal nerve fiber layer (RNFL) thickness with visual field changes in glaucomatous, ocular hypertensive and normal eyes.

Materials And Methods: Thirty consecutive normal, 30 consecutive ocular hypertensive and 30 consecutive glaucomatous eyes underwent a complete ophthalmic examination, including applanation tonometry, disc evaluation, (30-2) Humphrey field analyzer white on white (W/W) perimetry and short- wavelength automated perimetry. Thickness of the RNFL around the optic disc was determined with 3.

Simplified technique for deep anterior lamellar keratoplasty.

Purpose: To describe a new technique for performing deep anterior lamellar keratoplasty (DALK) that can be done without special instruments and where deep stromal dissection can be performed under direct visualization.

Methods: In this prospective, noncomparative case series, DALK was performed by first creating a scleral pocket incision to initiate corneal dissection and continuing further dissection under direct visualization after partial trephination. Fourteen eyes of 13 patients with corneal pathology not involving endothelium were operated on by using the new technique.

Comparison of in vitro susceptibilities of ocular bacterial isolates to gatifloxacin and other topical antibiotics.

Purpose: To compare the in vitro activity of gatifloxacin with that of other topical antibiotics against fresh bacterial isolates from various types of human ocular infections.

Methods: A total of 498 strains of ocular bacterial isolates were tested for their susceptibility to gatifloxacin, ofloxacin, ciprofloxacin, norfloxacin, gentamicin, tobramycin, neomycin, chloramphenicol, erythromycin, tetracycline and amikacin.

Results: Ninety-nine percent of gram-positive and 92% of gram-negative bacterial strains were found to be susceptible in vitro to gatifloxacin, whereas lower percentages of gram-positive and gram-negative bacteria were found to be susceptible to other antibiotics.

Subretinal fluid analysis in the diagnosis of choroidal tuberculosis.

Background: Diagnosis of intraocular tuberculosis is often difficult. A choroidal granulomalike lesion suspected to be the result of tuberculosis could be of other inflammatory, infective, or neoplastic causes. We report two cases in which a choroidal granuloma with exudative retinal detachment was diagnosed as tuberculosis by the detection of acid-fast bacilli in subretinal fluid.
