PurposeThe aim of the study was to analyze the effects of uneventful phacoemulsification surgery on choroidal thickness (CT) using spectral domain optical coherence tomography (SD-OCT).MethodsIn this prospective study, 38 eyes of 38 patients having phacoemulsification surgery were included. All patients underwent detailed ophthalmologic examination, including preoperative axial length (AXL) measurement with optical biometry and intraocular pressure (IOP) measurement preoperatively and 1 month postoperatively. The CT was measured perpendicularly at the fovea and 1.5 mm temporal, 3.0 mm temporal, 1.5 mm nasal, and 3.0 mm nasal using SD-OCT preoperatively and 1 month postoperatively. Changes in the CT after surgery and correlation of this change with age, AXL, preoperative IOP, and IOP change were evaluated.ResultsThere was a statistically significant increase in the CT at all regions evaluated. This increment was more prominent in the nasal and subfoveal regions. The IOP decreased significantly 1 month after surgery (16.14±4.94 mmHg vs 13.91±4.86 mmHg; P<0.001). The change in IOP was correlated with the CT changes at all regions, whereas age, AXL, and preoperative IOP had no significant correlations with the changes in CT.ConclusionPhacoemulsification surgery may cause significant increase in CT, which is correlated with surgery-induced IOP change in the short term. Long-term follow-up of eyes having phacoemulsification surgery may provide further insight into the effects of cataract surgery on the choroid.

Purpose. To investigate the oxidant and antioxidant status of patients with type 2 diabetes mellitus and nonproliferative diabetic retinopathy (DRP). Methods. Forty-four patients who had cataract surgery were enrolled in the study. We included 22 patients with DRP in one group and 22 patients in the control group. Samples of aqueous humor and serum were taken from all patients. Serum and aqueous ischemia-modified albumin (IMA), total thiol, total antioxidant capacity (TAC), and total oxidative stress (TOS) levels were compared in two groups. Results. Median serum IMA levels were 44.80 absorbance units in the DRP group and 40.15 absorbance units in the control group (P = 0.031). Median serum total thiol levels in the DRP group were significantly less than those in the control group (3051.13 and 3910.12, resp., P = 0.004). Mean TOS levels in the serum were 2.93 ± 0.19 in the DRP group and 2.61 ± 0.26 in the control group (P = 0.039). The differences in mean total thiol, TAC, and TOS levels in the aqueous humor and mean TAC levels in the serum were not statistically significant. Conclusion. IMA, total thiol, and TOS levels in the serum might be useful markers in monitoring the risk of DRP development.

We report an unusual case of tularemia involving pseudoptosis associated with deterioration of the lymphatic drainage system extending from the upper eyelid to the preauricular lymph nodes. A 16-week pregnant patient was admitted with an absess on the neck, preauricular lymphadenopathy, and pseudoptosis on the left side. The micro-agglutination test was positive for Francisella tularensis antibody at a titer of 1/200. The absess was surgically drained and oral cefuroxime was given for 6 weeks. Two weeks after drainage, the pseudoptosis improved due to the recovery of lymphatic drainage system of the eyelid and remission of the absess on the neck. Our case report contributes to the medical literature on tularemia during pregnancy and informs healthcare professionals on the management of the infection in such cases.

The aim of this study was to investigate the mean platelet volume (MPV) of patients with central serous chorioretinopathy (CSCR). Thirty patients were included in the study. Thirty healthy volunteers were recruited as the control group. All patients and control subjects underwent complete ocular examination. Hemoglobin, hematocrit, white blood cell, neutrophil, lymphocyte, platelet count, and MPV of the participants were recorded. Data of patients with CSCR were compared with the control subjects. Patients with CSCR had significantly higher MPV values (9.76 ± 1.36 fL) compared with the control subjects (8.37 ± 0.72 fL) (p = 0.004). No significant difference was found in platelet counts between the CSCR group and the control group (259 ± 53.75 and 243 ± 52.11 K/Ul, p = 0.253). According to the receiver operator characteristics curve analysis, the optimal cut-off value of MPV to predict the CSCR was >9.4, with 60.0 % sensitivity and 93.3 % specificity. Our results demonstrated that the MPV values were significantly higher in patients with CSCR. MPV may be used as a predictive tool for identifying risk for CSCR.
