Experience of intravitreal triamcinolone acetonide for treatment of diabetic macular edema among Omani population.

Purpose: The purpose of this study was to evaluate the outcome of intravitreal (IVT) triamcinolone in diabetic macular edema (DME).

Materials And Methods: A retrospective study of 42 eyes diagnosed clinically and supported with optical coherence tomography (OCT), with DME of more than 300 μm in thickness. All eyes were injected with a single IVT injection of preservative free triamcinolone acetonide (TA) with dose of 4 mg.

Visual outcome following extracapsular cataract extraction in mature cataracts with pseudoexfoliation syndrome: A retrospective study.

Purpose/objective: To report the best corrected visual acuity, at the end of one year, in 33 patients (35 eyes), who underwent extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens implantation (PC-IOL) for mature and hypermature cataracts, with pseudoexfoliation (PEX).

Design: Retrospective, non-comparative, single-institutional (Sultan Qaboos University Hospital) study.

Participants: Thirty-three patients with mature and hypermature cataracts, with PEX operated upon between January 2007 and December 2008, by one surgeon (AM).

Optical coherence tomography: clinical applications in medical practice.

Optical Coherence Tomography (OCT) is a success story of scientific and technological co-operation between a physicist and a clinician. The concept of cross-sectional imaging revolutionalized the applicability of OCT in the medical profession. OCT is a non-contact, topographic, biomicroscopic device that provides high resolution, cross-sectional digital images of live biological tissues in vivo and in real time.

Confoscan: an ideal therapeutic aid and screening tool in acanthamoeba keratitis.

Although present worldwide, Acanthamoeba keratitis (AK) is a rare condition. It is a protozoal infection of the eye that is generally caused by wearing contaminated contact lenses or lens solutions. Confoscan and confocal scanning laser tomography (CSLT) are in vivo noninvasive diagnostic tools which provide high definition images of corneal microstructures.

Frosted branch angiitis, neuroretinitis as initial ocular manifestation in Behçet disease.

Behçet disease is an idiopathic, multisystem disorder characterized by recurrent episodes of orogenital ulceration and vasculitis of the veins and arteries of all calibers. Ocular involvement may affect the conjunctiva, sclera, uveal tract, vitreous, blood vessels, and retina. Many theories have pointed toward an autoimmune response behind its pathogenesis, which may be triggered by exposure to an infectious agent.

Total levator aponeurosis resection for primary congenital ptosis with very poor levator function.

Aim: This study was designed to evaluate the effectiveness of total levator aponeurosis resection in patients with very poor levator function secondary to primary congenital ptosis.

Design: A retrospective, noncomparative single-institutional study was designed.

Participants: Seven patients with very poor levator function secondary to primary congenital ptosis operated between May 2008 and May 2010 by one surgeon (AM).

Sebaceous gland carcinoma of the eyelid.

Sebaceous gland carcinoma, commonly arises in the periocular area, is an uncommon condition. It represents 1-5.5% of eyelid malignancies and is considered to be the third most common eyelid malignancy after basal cell and squamous cell carcinomas, although few reports placed this tumor as second most common after basal cell carcinoma.

Subjective and quantitative measurement of wavefront aberrations in nuclear cataracts - a retrospective case controlled study.

Purpose: To measure, quantify and compare Ocular Aberrations due to nuclear cataracts.

Setting: Department of ophthalmology and school for ophthalmic technicians, college of medicine and health sciences, Sultan Qaboos University, Muscat, Oman.

Design: Retrospective case controlled study.

Culture Negative Confoscan Positive Acanthamoeba Keratitis: A relentless course.

Acanthamoeba keratitis is a protozoal infection of the eye, mainly due to the use of non-sterile solutions, like saline for disinfecting contact lenses. We report a case where delay in the diagnosis of acanthamoeba keratitis due to inadequate laboratory investigations and clinical management led to an excruciatingly painful course of the disease. The importance of non-invasive imaging techniques of confocal microscopy in the diagnosis of acanthamoeba keratitis, in the absence of positive culture reports, is highlighted in this case.

Bacterial keratitis: perspective on epidemiology, clinico-pathogenesis, diagnosis and treatment.

Bacterial keratitis is an acute or chronic, transient or recurrent infection of the cornea with varying predilection for anatomical and topographical parts of the cornea like marginal or central. It is a potentially sight-threatening corneal infection in humans that is generally found in eyes with predisposing elements, the most common of which is contact lens wear. The epidemiological data reveals the universal occurrence of this disease.

Bevacizumab therapy for macular edema in central retinal vein occlusion: Long-term results.

Background: There is no proven effective treatment for vision loss in central retinal vein occlusion (CRVO). Bevacizumab has been reported in small series with limited follow-up, to have a positive effect in reducing cystoid macular edema (CME) and improving vision in CRVO.

Purpose: To report long-term results with the use of bevacizumab in CRVO.

In vivo morphometry of corneal endothelial cells in pseudoexfoliation keratopathy with glaucoma and cataract.

Background: This study was designed to define correlations between in vivo morphometric and demographic data of pseudoexfoliation (PEX) keratopathy patients from Omani Arab origin with cataract and glaucoma.

Methods: In a non-randomized controlled comparative case series, 69 adult patients (43 males and 26 females) with 78 cataract and 48 glaucoma eyes with corneal PEX material were assessed by confocal biomicroscopy (Confoscan 2, Nidek) and values compared to normative US and Omani Arab population values. Descriptive statistics.

Quantitative and qualitative corneal endothelial morphology of omani patients with pseudoexfoliation syndrome.

Objective: Pseudoexfoliation (PEX) syndrome is one of the leading causes of secondary open angle glaucoma and blindness. This study explored whether in PEX eyes, preoperative changes in corneal endothelial cell morphology might be a risk factor for postoperative corneal decompensation.

Methods: One hundred twenty six eyes of 69 preoperative cataract patients (43 males, 26 females) were enrolled in this cross-sectional study from the Ophthalmology Department at Sultan Qaboos University Hospital between 2003-2005.

Photodynamic therapy with verteporfin for chronic central serous choroidoretinopathy and idiopathic choroidal neovascularization-first report from the sultanate of oman.

Background: Central Serous Chorioretinopathy (CSCR) is characterized by accumulation of subretinal fluid, resulting in neurosensory retinal detachment.

Design: Interventional study.

Methods: Five patients (CSCR-3; Idiopathic-2) with Choroidal Neovascularization (CNV) were selected for the study.
