Background:  The aim was to evaluate anterior segment parameters in patients with pseudoexfoliation syndrome (PXS) or pseudoexfoliative glaucoma (PXG) with the Pentacam‐Scheimpflug imaging system. Methods:  Eighty eyes of 53 patients with PXS (Group 1), 80 eyes of 57 patients with PXG (Group 2) and 80 eyes of 45 control cases (Group 3) were included in the study. Anterior chamber depth, volume (ACV), angle (ACA) width, central corneal thickness (CCT), central 3.0, 5.0 and 7.0 mm corneal volumes and pupil diameters were compared between groups. Results:  Although anterior chamber depths in the PXG group were significantly lower than the control group (p < 0.05), there was no statistically significant difference between the PXS group and the control group in means of anterior chamber depth values (p > 0.05). There were no statistically significant differences among PXS, PXG and the control group in mean values of ACV, ACA width, CCT, pupil diameters and central 3.0, 5.0 and 7.0 mm corneal volume (p > 0.05). Conclusions:  The anterior chamber depths of PXG patients were lower than those of healthy individuals. Although the difference in anterior chamber depth between PXG patients and normal patients was statistically significant, this finding is unlikely to be of clinical significance. The anterior chamber depths of PXS patients were similar to those of healthy individuals. There were no significant differences in the means of ACV, ACA width, CCT, pupil diameter and corneal volume values on central 3.0, 5.0 and 7.0 mm among patients with PXS, PXG and healthy individuals.

Purpose To determine whether metabolite changes at cellular level occur in vitreous and lateral geniculate body (LGB) in patients with glaucoma by magnetic resonance spectroscopy (MRS). Methods A total of 29 eyes of 29 patients with glaucoma, no existing ocular pathology and systemic disease (group 1), and 13 eyes of 13 healthy individuals whose routine ophthalmological examinations were normal (group 2) were included in the study. Singlevoxel MRS examination was performed by placing region of interest in vitreous and LGB. Glutamate-glutamine (Glx)/creatin (Cr) ratios and lactate peaks in the vitreous, and the Glx/Cr, N-acetyl aspartate (NAA)/Cr, choline (Cho)/Cr ratios in the ipsilateral area of LGB were evaluated. Results A statistically significant difference was found between the two groups for the Glx/Cr ratio in both the vitreous and LGB (P ¼ 0.0001). There was no statistically significant difference between the two groups for the NAA/Cr, and Cho/Cr ratios in the LGB (P ¼ 0.108). A lactate peak was established in the vitreous of 11 glaucoma patients. Conclusion Determining increased Glx/Cr ratios in both the vitreous and LGB of glaucoma patients, supports the theory of apoptosis in the etiopathogenesis of glaucoma. The MRS method, which can measure biochemical structures and metabolites of tissues, and also shows on a single spectrum, may be a new and noninvasive method for confirming the diagnosis of glaucoma and the role of apoptosis in the etiopathogenesis of glaucoma.

Laser refractive surgery is an effective option for improving the visual acuity in children with an amblyopic eye in association with anisometropia.

The increase of fluid in the body, in particular in the second and last trimester, may cause an increase of TMV and FT.

We present a case as a rare sign of traumatic optic neuropathy and central retinal artery occlusion following blunt ocular trauma. A 10-year-old child suffered complete loss of the vision of one eye following a blunt ocular injury. He sustained an occlusion of the central retinal artery and traumatic optic neurupathy of the affected eye. Isolated cases of central retinal vessel occlusions and traumatic optic neurapathy following ocular blunt trauma are rare conditions. Clinicians to be aware of the potential for blunt ocular trauma to cause optic nerve damage and retinal vessel occlusions.KeywordsBlunt ocular trauma; Retinal artery occlusion; Traumatic optic neuropathy

Purpose To evaluate the influence of silicone hydrogel contact lenses on the intraocular pressure (IOP) measurement using Goldmann applanation tonometry (GAT), non-contact tonometry (NCT), and Pascal dynamic contour tonometry (DCT). Methods We included in the study 40 eyes of 40 patients who did not have any ocular or systemic diseases or contraindications to contact lens use. We measured and recorded the IOP values of each patient using NCT without and with contact lenses (groups 1 and 2, respectively), using DCT without and with contact lenses (groups 3 and 4, respectively), and using GAT without contact lenses (group 5). Results The mean IOP value of group 1 was 14.55±2.95 mm Hg and 13.92±2.58 mm Hg in group 2. We detected no statistically significant difference between group 1 and group 2 (P ¼ 0.053). The mean IOP values for group 3 and group 4 were 16.26 ± 2.33 mm Hg and 15.19 ± 2.40 mm Hg, respectively. We detected a statistically significant difference between groups 3 and 4 (P ¼ 0.005).

Background Rosacea is an inflammatory disease with 50% of ocular involvement rate. Primary demodicosis is an eruption caused by Demodex mites, and there is no data about the rate of ocular involvement in primary demodicosis. Aims In this cross‐sectional study, it is aimed to reveal the frequency of Demodex blepharitis in rosacea and primary demodicosis patients. Methods In total, 58 rosacea, 33 primary demodicosis patients, and 31 healthy volunteers were included in the study. Four samples were obtained from eyelashes with a forceps and from facial skin by standardized skin surface biopsy. A positive result is described as detecting at least one Demodex mite on an eyelash or at five mites in the face. The patients were also examined by an ophthalmologist in terms of ocular involvement. Results Both rosacea and primary demodicosis patients had significantly more complaints like burning and stinging in the eyes compared to the control patients (P = .001). Primary demodicosis and papulopustular rosacea patients had the highest numbers of eyelash mites, respectively, and significantly a higher rate of blepharitis than the control group. Conclusion As a result, the Demodex count was significantly higher in the primary demodicosis and rosacea patients than the control group. We think that every Demodex‐positive patients should be evaluated for also eyelash mites to prevent a possible chronic blepharitis.

Patients with strabismus who undergo recession plus resection procedure are prone to change in anterior chamber volume. Study with larger groups and long follow-up is necessary for clearer documentation of alterations at anterior chamber parameters.
