We report the case of an eight-year-old male patient with a four-month history of unilateral anterior chronic uveitis, associated with a pigmented lesion surrounded by fibrinoid material in the inferior camerular angle and with a fibrotic lesion in the extreme periphery of the inferior retina. The patient had no history of trauma or any other clinical symptoms. Although the patient was suspected of having toxocariasis, serological tests were negative. RGDyK price Partial symptomatic improvement was achieved using both orally and topically administered corticosteroids. In addition, a decrease in fibrinoid material around the pigmented camerular lesion revealed it to be regular and cylindric. Computed tomography of the orbits revealed a metallic foreign body in the topography of the inferior camerular angle. The patient underwent removal of the foreign body through a corneal incision and photocoagulation around the inferior retinal traction. Excellent visual and anatomical results were obtained.

This study aimed to investigate the effect of using a viscoelastic substance in Descemet's membrane rupture in "double bubble" deep anterior lamellar keratoplasty.

The medical records and videos of surgeries of 40 patients who underwent surgery between January 2014 and July 2015 were retrospectively evaluated. The patients were divided into two groups 20 patients whose perforation of the posterior stromal wall was performed without administration of any viscoelastic substance (group 1) and 20 patients whose perforation of the posterior stromal wall was performed with administration of viscoelastic substance onto the posterior stroma (group 2). The Descemet's membrane perforation rate was compared between groups.

Perforation of the Descemet's membrane was observed in 12 (60.0%) patients in group 1 and only three (15.0%) patients in group 2. This difference was statistically significant (p=0.003). Only one (5%) patient in group 2 had macroperforation during the procedure, and the surgery was converted to penetrating keratoplasty. Eleven (55.0%) patients in group 1 had macroperforation of Descemet's membrane, and surgeries were converted to penetrating keratoplasty. This difference between the groups was statistically significant (p=0.001).

Administering a viscoelastic substance onto the posterior stromal side just before puncture is an effective method to decrease the risk of Descemet's membrane perforation in deep anterior lamellar keratoplasty.

This study was conducted to evaluate visual function and changes in the central macular thickness of patients with unresponsive neovascular age-related macular degeneration who were switched from ranibizumab (Lucentis®) to aflibercept (Eylea®) treatment at 30 months.

This retrospective study examined patients with neovascular age-related macular degeneration who were switched to aflibercept after ≥6 previous intravitreal ranibizumab injections at 4- to 8-week intervals. All patients were switched to intravitreal aflibercept (2.0 mg) and analyzed after 3 consecutive injections followed by a prore nata dosing regimen and after 30 months of treatment. Best corrected visual acuity, biomicroscopic examination, intraocular pressure, fundus examination, and central macular thickness were recorded at the start of treatment, before the transition to intravitreal aflibercept treatment, and at 6, 12, 18, 24, and 30 months of intravitreal aflibercept treatment.

A total of 33 eyes met the inclusion criteria. The meddue to unresponsiveness to intravitreal ranibizumab exhibited a significant anatomic improvement in the retina, and although this state persisted, there was no significant functional gain.

To identify the lymphatic vessels in orbital specimens from human cadavers using light microscopy and immunohistochemical analysis.

A postmortem study included 10 orbital specimens from 10 human cadavers. The orbital specimens were obtained no later than 12 hours after death. The orbital specimens were dissected into lacrimal gland, optic nerve, fat tissue, and oculomotor muscles. The histologic criteria to qualify as a lymphatic vessel were thin-walled channels of endothelium without a well-developed basal membrane and with an erythrocyte-free, irregular lumen. The immunohistochemical criteria were irregularly shaped, thin-walled vessels with an erythrocyte-free, irregular lumen and immunopositivity for podoplanin D2-40.

The lacrimal gland, optic nerve, fat tissue, and extraocular muscle sections were positively stained with podoplanin D2-40.

This study demonstrated lymphatic vessels in the human orbit, more precisely, in the lacrimal gland, dura mater of the optic nerve, adipose tissue, and extrinsic oculomotor muscles via light microscopy and immunohistochemistry.

To comparatively assess the macular sensitivity threshold of microperimetry and the fixation stability between the first (right) and second (left) tested eye of normal participants.

Thirty healthy patients were randomly assigned to two groups. The participants underwent microperimetry in the fast mode and expert mode in groups I and II, respectively. Each participant underwent a single test and the right eye was tested first.

The mean macular sensitivity threshold (± standard deviation [SD]) was 24.5 ± 2.3 dB and 25.7 ± 1.1 dB in the first (right) and second (left) eyes of group I, respectively (p=0.0415) and 26.7 ± 4.5 dB and 27.3 ± 4.0 dB in the first (right) and second (left) eyes of group II, respectively (p=0.58). There was no statistically significant difference between eyes in either group (p=0.1512). Regarding fixation stability (evaluated in the microperimetry expert mode group), the mean ± SD percentage of fixation points within the 1-degree central macula (P1) was 87.9 ± 11.5% in the right eye and 93.
