Effect of accelerated corneal crosslinking on ocular response analyzer waveform-derived parameters in progressive keratoconus.

Purpose: To evaluate the effect of accelerated corneal crosslinking on corneal biomechanics with an ocular response analyzer in patients with progressive keratoconus.

Methods: In this retrospective study, 50 eyes of 45 patients with progressive keratoconus who underwent accelerated corneal crosslinking were evaluated with ocular response analyzer waveform parameters before and one year after corneal crosslinking. Paired two-tailed Student's t-test was performed to compare the parameters before vs.

Applications of different types of gas-permeable contact lenses in keratoconus and their visual results.

Purpose: To show applications of different types of gas-permeable contact lenses in patients with keratoconus and to compare visual acuity (VA) results.

Methods: A total of 229 eyes of 133 patients who used different types of rigid gas-permeable contact lenses between April 2003 and April 2010 at the Cornea and Contact Lens Unit of Eye Clinic 2 of the Ministry of Health, Ulucanlar Eye Training and Research Hospital, were included. Visual acuity of patients was classified as uncorrected and corrected with eyeglasses and corrected with contact lenses.

The effect of contact lens usage on corneal biomechanical parameters in myopic patients.

Purpose: To determine and compare the corneal biomechanical properties in myopic patients who use contact lenses and those who do not use contact lenses.

Methods: The study consisted of 56 myopic patients who used contact lenses (study group) and 123 myopic patients who did not use contact lenses (control group). Intraocular pressure (IOP) was measured with an ocular response analyzer (ORA) and a Goldmann applanation tonometer.

Optic disc and retinal nerve fiber layer parameters of eyes with keratoconus.

Background And Objective: To evaluate optic nerve head (ONH) characteristics and retinal nerve fiber layer (RNFL) thickness measurements in patients with nonglaucomatous keratoconus.

Patients And Methods: This was a cross-sectional, observational study in which 46 patients with keratoconus and 74 healthy subjects were included. Analysis of ONH and RNFL imaging were performed by confocal scanning laser ophthalmoscopy and optical coherence tomography, respectively.

A comparative study of tissue glue and vicryl suture for closing limbal-conjunctival autografts and histologic evaluation after pterygium excision.

Purpose: To compare clinical and histopathologic outcomes of tissue glue and vicryl suture to attach limbal conjunctival autografts in pterygium surgery.

Methods: Twenty-four eyes of 24 patients were included in this study. All eyes had primary pterygia and were treated with limbal conjunctival autograft transplantation after pterygium resection.

Does blunt ocular trauma induce corneal astigmatism?

Purpose: To determine the effect of blunt ocular trauma on refractive astigmatism.

Methods: Eighty-six eyes of 86 patients with known previous refractive status exposed to blunt ocular trauma were included in the study. Trauma-induced astigmatism (TIA) was calculated using vector analysis.

Lower lid retraction: a valuable finding in juvenile Graves' orbitopathy.

Purpose: To evaluate the findings of juvenile Graves' orbitopathy.

Subjects And Methods: Retrospective evaluation of our patients with Graves' disease who are younger than 16 years.

Results: Seventeen patients younger than 16 years were identified among 138 patients who were being treated for hyperthyroidism and goiter.

Monocular temporal hemianopia in a young patient.

A 12-year-old girl presented with a history of sudden visual hemi-field loss in the left eye. The visual field defect was a clear-cut temporal hemianopia in the left eye; eye was normal. Complete eye examination and neuro-imaging of brain and opto-chiasmal region revealed normal structural findings.
