Comparison of peripapillary vascular density as measured by optical coherence tomography angiography between various types of open-angle glaucoma.

Purpose: The purpose of this study is to compare the peripapillary vascular density in patients with various types of open-angle glaucoma (primary open-angle glaucoma, pseudoexfoliative glaucoma and pigmentary glaucoma) with healthy subjects by optic coherence tomography angiography (OCTA).

Methods: Twenty-seven eyes with diagnosed POAG, thirty-four eyes with diagnosed PXG, twenty eyes with diagnosed PG and thirty eyes of healthy individuals were included in our study. Peripapillary vessel density measurements were performed with all images; (AI-DD), intra-disc (ID-DD) and peripapillary (PP-DD); measurement of vascular density in the radial peripapillary capillary network was performed by OCTA.

Comparison of the results of four different refraction measurement devices in children with retinoscopy.

The purpose of this study was to compare the results of 4 different autorefractometer devices with the results of retinoscopy in children. A total of 120 eyes of 60 patients aged between 6 and 18, who applied to Afyonkarahisar Health Sciences University unit of Pediatric Ophthalmology, were included in the study. Refraction with Plusoptix A09 (photoscreener) without cycloplegia was the first to be measured.

Prevalence of amblyopia in children undergoing nasolacrimal duct irrigation and probing.

Purpose: To investigate ambylopia and amblyopia risk factors of children who underwent nasolacrimal duct (NLD) irrigation and probing for congenital nasolacrimal duct obstruction (CNLDO).

Materials And Methods: The medical records of patients who had undergone NLD irrigation and probing for CNLDO at an age of 3 years or younger were reviewed, and 51 of the patients were recalled between October 1 and December 31, 2011 for a detailed ophthalmic examination to determinate amblyopia or amblyopia risk factors. Amblyopia was accepted as difference in visual acuity of two or more Snellen lines between the two eyes or visual acuity of 20/30 or worse in either eye.

A comparison of different autorefractors with retinoscopy in children.

Purpose: To compare the results of different refractive error measurement devices including table-mounted and hand-held autorefractors and videoretinoscopy with cycloplegic retinoscopy (CR) in children to evaluate the usability and reliability of these devices in measuring refractive errors.

Methods: Two hundred eyes of 100 children underwent autorefraction using table-mounted autorefractor with and without cycloplegia and videoretinoscopy after cycloplegia. All results were compared statistically.

Congenital ptosis and amblyopia.

Purpose: To investigate the incidence and causes of amblyopia in congenital ptosis.

Methods: The frequency and causes of amblyopia were evaluated in 83 eyes of 72 patients with congenital ptosis. Patient ages ranged between 10 months and 70 years.

Comparison of the effects of dorzolamide-timolol fixed combination and brimonidine on intraocular pressure after phacoemulsification surgery.

Purpose: To compare the effects of dorzolamide-timolol combination and brimonidine on intraocular pressure (IOP) after phacoemulsification surgery.

Methods: This prospective, randomized study included 69 eyes of 43 patients undergoing phacoemulsification and foldable intraocular lens implantation. Twenty-one patients were women and 22 were men.

Astigmatism after superonasal and superotemporal clear corneal incisions in phacoemulsification.

Purpose: To determine the astigmatism outcomes after cataract surgery performed using superonasal and superotemporal clear corneal incisions.

Setting: Department of Ophthalmology, Kartal Training and Research Hospital, Istanbul, Turkey.

Methods: This prospective study includes consecutive 45 eyes of 34 patients having phacoemulsification with implantation of foldable acrylic intraocular lens through a corneal tunnel incision between January and April 2004.

A retrospective case series: use of SoftPerm contact lenses in patients with keratoconus.

Purpose: To evaluate the performance of the SoftPerm contact lens in patients with irregular astigmatism caused by keratoconus.

Methods: Twenty-four eyes of 14 patients with keratoconus who had intolerance to rigid gas-permeable contact lenses and were fitted with SoftPerm lenses at Kartal Training and Research Hospital between August 1998 and January 2002 were evaluated retrospectively. The average follow-up time was 23 months.

Pseudallescheria boydii keratitis.

We describe a patient with Pseudallescheria boydii keratitis. The treatment of mycotic keratitis remains difficult. This case demonstrates that identification and susceptibility testing should be rapidly performed.

Therapeutic applications of lotrafilcon a silicone hydrogel soft contact lenses.

Purpose: To investigate the effectiveness of silicone hydrogel soft contact lenses for therapeutic applications.

Methods: The study included 37 patients who had bullous keratopathy (n=12), recurrent corneal erosion (n=9), filamentous keratitis (n=3), corneal melting after corneal surgery (n=4), lamellar lacerations (n=4), or chemical trauma (n=5) and were fitted with silicone hydrogel soft contact lenses between May 2000 and August 2003 in First Eye Clinic of Kartal Training and Research Hospital. Changes in corneal signs by slitlamp evaluation, judgment of pain relief, additional complications, and success of therapeutic lens treatment were reported.

Exodeviation following monocular myopic regression after laser in situ keratomileusis.

We report a 44-year-old woman with intermittent left exotropia of 35 prism diopters at distance who initially exhibited alignment of both eyes after bilateral laser in situ keratomileusis (LASIK). The exophoria was not preserved due to myopic regression in the dominant eye. An uneventful LASIK treatment was performed to correct -11.

Magnetic resonance imaging in Duane's retraction syndrome.

Purpose: The aim of this study was to visualize the subarachnoid portion of the nervus abducens by magnetic resonance imaging and to analyze whether aplasia of the nervus abducens is an etiologic factor in Duane's retraction syndrome.

Methods: We performed thin-sectioned magnetic resonance imaging across the brainstem level in 8 cases (11 eyes) that were clinically diagnosed as Duane's retraction syndrome. The same test was applied to 8 healthy control subjects to verify the accuracy of this technique.
