We detected RNFL and macular thinning in patients with schizophrenia. Based on these findings and results of other studies evaluating retina using OCT and brain magnetic resonance imaging studies in patients with schizophrenia, a neurodegenerative process may be an underlying pathologic mechanism in this disease.

The findings showed that accelerated CXL treatment seems to be effective in slowing or halting the progression of keratoconus and that no permanent apparent complications are noted 6 months after accelerated CXL.

Registration number of clinical trials registry: 2013/43-16. ABSTRACTPurpose: To evaluate the association between macular hole volume (MHV) and postoperative central macular thickness (CMT) using spectral-domain optical coherence tomography (SD-OCT). Methods: Thirty-three eyes of 30 patients with a large full-thickness idiopathic macular hole with or without vitreomacular traction who underwent surgical intervention were included in this cross-sectional study. Complete ophthalmological examination, including SD-OCT, was performed for all participants during the pre-and postoperative visits. MHV was preoperatively measured using SD-OCT, which captured the widest cross-sectional image of the hole. For normal distribution analysis of the data, the Kolmogorov-Smirnov test was performed, and for statistical analyses, chi-square, Student's t-test, Mann-Whitney U test, and Pearson's correlation coefficient test were performed. Results: Mean preoperative best-corrected visual acuity (BCVA) and MHV were found to be 0.99 ± 0.36 (range, 0.3-2.0) logMAR and 0.139 ± 0.076 (range, 0.004-0.318) mm 3 , respectively. Mean follow-up was 16.3 ± 14.3 (range, 3-50) months. No statistical correlations were found between MHV and postoperative BCVA (p=0.588) and between MHV and disease recurrence (p=0.544). A weak negative correlation existed between MHV and final CMT scores (p=0.04, r=-0.383). Conclusions: Greater MHV was found to be weakly associated with lower postoperative CMT scores.

The aim of this study was to evaluate the central retinal thickness (CRT), outer nuclear layer thickness (ONLT), photoreceptor layer thickness (PLT), photoreceptor layer integrity, and the correlation between visual acuity and PLT in eyes with branch retinal vein occlusion (BRVO) 2 months after treatment with intravitreal dexamethasone implant (Ozurdex; Allergan, Inc, Irvine, CA). In this prospective study, 32 eyes of 32 patients were enrolled. A single injection of Ozurdex was administered to all the patients. CRT, ONLT, and PLT were measured using spectral-domain optical coherence tomography before and 2 months after the injection. Best-corrected visual acuity (BCVA [logMAR]) and photoreceptor cell integrity were also evaluated. The average CRT, ONLT, PLT, and BCVA values for the sample group before the treatment were as follows: 707 ± 261, 608 ± 288, 70 ± 25, and 0.96 ± 0.22 µm, respectively. The average CRT, ONLT, PLT, and BCVA values for the sample group 2 months after the Ozurdex injection were as follows: 299 ± 149, 211 ± 138, 77 ± 20, and 0.63 ± 0.30 µm, respectively (p < 0.05). Two months after the Ozurdex injection, BCVA correlated with ONLT and PLT (r = 0.365, p = 0.048 and r = -0.488, p = 0.021, respectively), whereas BCVA was not correlated with CRT (r = 0.239, p = 0.189). Photoreceptor layer is associated with the visual function of eyes with macular edema secondary to BRVO. Also, ONLT seems to be more closely related to visual acuity improvement than CRT decrement.

An increase in MT can be observed after Nd:YAG laser capsulotomy, especially in diabetic patients. Adding topical ketorolac (Acular®, Allergan, Irvine, CA) to topical Fluorometholon (FML®, Allergan, Irvine, CA) therapy after YAG laser capsulotomy can prevent this increase.
