RESUMEN
PURPOSE: To evaluate the importance of the status of posterior vitreous in eyes with endophthalmitis following intravitreal anti-vascular endothelial growth factor (anti-VEGF). METHODS: The absence or existence of posterior vitreous detachment (PVD) was elicited in 23 eyes of 23 patients with injection related endophthalmitis, during pars plana vitrectomy (PPV) and compared with 24 control eyes of 24 patients who received intravitreal anti-VEGF without any complication. RESULTS: Thirtten (54.2%) out of 24 patients in the control group had full PVD, whereas only 2 (9.5%) out of 23 eyes in endophthalmitis group (p < 0.001) had full PVD. In all eyes without PVD, posterior vitreous was inducted to be detached at least from optic nerve and macular area without any iatrogenic tear. CONCLUSION: The absence of PVD is a factor that increases the risk of endophthalmitis after intravitreal injections. Uncomplicated separation of the posterior vitreous from the retina in PPV contributes to better prognosis.

PURPOSE: To evaluate the retinal and choroidal vascular structures in patients with anxiety disorders. METHODS: Thirthy-four eyes of 34 patients who were diagnosed with any anxiety disorders were compared with 32 eyes of 32 age- and sex-matched controls. Central macular thickness (CMT), foveal vascular zone (FAZ) area, total retinal vascular densities of superficial and deep capillary plexus (VDSCP, VDDCP), outer retinal and choriocapillary layers (ORL, CCL) blood flow rates, central subfoveal choroidal thickness (SFCT) and choriodal vascularity index (CVI) were evaluated with optical coherence tomography angiography (OCT-A) and enhanced depth imaging optical coherence tomography (EDI-OCT). RESULTS: No statistical differences were found between the study and control groups in terms of CMT, FAZ area, VDSCP, VDDCP, ORL and CCL blood flow rates. The mean SFCT was 346.26 ± 64.26â µm in patients with anxiety disorder and was found to be statistically significantly thicker than the control group (319.56 ± 37.19â µm) (p = 0.042). Besides, CVI was significantly lower in the study group (71.09 ± 2.64 vs 73.13 ± 3.31, p = 0.008). CONCLUSION: In people with anxiety disorders, the SFCT was found to be thicker and CVI was found to be lower than normal subjects. Although anxiety and stress are important factors in central serous chorioretinopathy, multifactorial factors, including ocular factors, play a role in the pathophysiology of the disease. There is a need for prospective studies with larger series on the subject.

AIM: To elucidate the relationship between systemic risk factors and different patterns of diabetic macular edema (DME) determined with optical coherence tomography (OCT). METHODS: In this cross-sectional study, DME was classified by OCT as diffuse retinal thickness (DRT), cystoid macular edema (CME) and serous retinal detachment (SRD) and the relationship between the systemic risk factors and DME patterns was evaluated. RESULTS: Of the 57 patients with DME, 21 (36.8%) had DRT, 24 (42.1%) had CME and 12 (21.0%) had SRD. Micro- or macro-albuminuria was significantly higher in the DRT pattern (61.9%) compared with the SRD (50.0%) and CME patterns (25.0%; P=0.040). Hemoglobin A1c (HbA1c) level was significantly higher and patients were younger in the DRT pattern group (P=0.034, P=0.032). Best corrected visual acuity was the worst and central macular thickness was the thickest in the CME pattern group. CONCLUSION: Micro- or macro-albuminuria may be more frequent and HbA1c level may be higher in patients with DRT. These patients are also seen to be younger than patients with non-DRT.
RESUMEN
BACKGROUND: The aim of this study was to evaluate the prevalence of diabetic macular edema (DME) utilizing optical coherence tomography (OCT), and to clarify the effects of the systemic findings and risk factors on the development of DME. METHODS: This cross-sectional study was conducted in the departments of ophthalmology and endocrinology at the Dokuz Eylul University School of Medicine in Izmir, Turkey. The demographics, type and duration of diabetes mellitus, treatment modality, smoking and alcohol consumption habits, as well as the systemic blood pressure, renal functional tests, hemoglobulin A1c level, serum lipid profile, and 24-h urine albumin level were noted and statistically analyzed. The relationships between the systemic findings and DME were studied. RESULTS: Four-hundred and thirteen eyes of 413 diabetic patients who were examined between January 2011 and July 2012 were enrolled in this study. The prevalence of DME was 15.3% among the patients. The males exhibited DME significantly more frequently than the females (p = 0.031), and the duration of diabetes was significantly longer in those patients with DME (p < 0.001). Those patients without DME frequently used antihyperlipidemic drugs and had a higher level of high density lipoprotein cholesterol (p = 0.040 and p = 0.046, respectively). The patient's alcohol consumption, nephropathy, neuropathy, previous cataract surgery, severity of diabetic retinopathy, and insulin usage were statistically significant factors with regard to the DME prevalence. CONCLUSIONS: This study demonstrated the prevalence of DME in Turkey by utilizing OCT. The development of DME can be avoided or limited and the response to treatment may be improved by the regulation of the DME risk factors.

BACKGROUND: To evaluate the ocular pulse amplitude (OPA) in patients with chronic non-arteritic anterior ischaemic optic neuropathy (NAION). METHODS: This cross-sectional study comprised a study group of 30 eyes from 30 patients with NAION and a control group of 31 eyes from 31 age and gender-matched healthy subjects. Bilateral OPA was measured with dynamic contour tonometry (DCT) and was compared between the study and control groups. RESULTS: No statistically significant difference was found between the study and control groups in terms of hypertension, diabetes mellitus, ischaemic heart disease and hyperlipidemia. The mean intraocular pressure (IOP) measured with Goldmann Applanation Tonometry and DCT in the study and control groups was not statistically different (p1 = 0.094, p2 = 0.240). The mean OPA in the study group and the control group were 2.01 ± 0.69 mmHg and 1.97 ± 0.68 mmHg (p = 0.839). CONCLUSION: No significant difference was determined in the OPA levels of eyes with NAION at the chronic stage and eyes in the control group.

BACKGROUND: Antidepressant drugs may have an effect on tear film stability. This study aimed to determine the influence of selective serotonin reuptake inhibitors, which are mostly prescribed antidepressants, on ocular surface and tear film stability. METHODS: Thirty-six patients (Group 1) and 36 healthy volunteers (Group 2) were enrolled. Group 1 comprised of depression and/or anxiety disorder patients using selective serotonin reuptake inhibitors, who were in clinical remission according to psychiatric history and questionnaires (Hamilton depression rating scale and Hamilton anxiety rating scale). All subjects underwent a detailed ophthalmological examination and the following tests were performed: corneal and conjunctival fluorescein staining and Oxford scoring, tear break-up time, Schirmer 1 test, ocular surface disease index score assessment. RESULTS: The mean age was 36.64 (18 to 61) years in Group 1 and 31.84 (18 to 48) years in Group 2 (p > 0.05). Male to female ratio was 0.38 in Group 1 and 0.89 in Group 2 (p > 0.05). In Group 1, 19 patients (52.8 per cent) had depression, 16 patients (44.4 per cent) had anxiety disorder and one patient (2.8 per cent) had a combination of depression and anxiety disorder. The mean tear break-up times in Groups 1 and 2 were 7.05 ± 4.86 and 12.53 ± 4.75 seconds, respectively (p < 0.001). The mean Schirmer 1 test results in Groups 1 and 2 were 14.44 ± 10.81 and 17.69 ± 10.46 mm, respectively (p > 0.05). The mean superficial punctate staining according to Oxford scale in Groups 1 and 2 were grade 0.78 ± 0.76 and grade 0.11 ± 0.32, respectively (p < 0.001). The mean ocular surface disease index scores in Groups 1 and 2 were 32.07 (zero to 75.00) and 16.31 (zero to 58.33), respectively (p < 0.001). CONCLUSION: Selective serotonin reuptake inhibitor usage might affect ocular surface by affecting tear film stability and such an association should be kept in mind by both psychiatrists and ophthalmologists in clinical practice.

This study aimed to examine the rate of symptomatic improvement of congenital nasolacrimal duct obstruction (CNLDO) in infants treated with conservative management within the first year of age. Other purpose of the study is to emphasize the relationship between spontaneous resolution time and effective lacrimal sac massage. Thirty-one infants were diagnosed to have CNLDO by an ophthalmologist prior to 3 months of age. In this study, 36 eyes of 31 patients were included with CNLDO. The patients were divided into two groups. Group 1 (28 eyes of 24 patients) was consisted of the patients who were applied effective lacrimal sac massage regularly during the follow-up period, and patients whose parents did not apply a regular lacrimal passage regularly were accepted as group 2 (8 eyes of 7 patients). Thirty-three eyes of 31 patients (18 rights and 15 left) successfully resolved with only conservative management (91.6 %). In these thirty-three eyes, one eye (3 %) resolved between 0 and 3 months, fourteen eyes (42.5 %) resolved between 4 and 6 months, eleven eyes (33.3 %) resolved between 7 and 9 months, and seven eyes (21.2 %) resolved between 10 and 12 months. CNLDO was resolved in 27 (96.2 %) of 28 eyes in group 1, and in group 2, six eyes (77.7 %) had resolvement. This difference was statistically significant (p = 0.001). The mean age of resolution was 6.8 ± 1.88 months in group 1, 10.3 ± 1.5 months in group 2 (p < 0.001). In light of our study, we believe that conservative management of CNLDO is highly successful. Our study provided a possible objective explanation for the efficacy of lacrimal sac massage. Emphasizing the importance of the massage to parents and describing in detail can reduce the risk of unnecessary surgical interventions.
