PLoS One 2019; 14:e0219505. [PMID: 31287835 PMCID: PMC6615605 DOI: 10.1371/journal.pone.0219505] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2018] [Accepted: 06/25/2019] [Indexed: 12/13/2022] Open
Abstract
Purpose The purpose of the present study was to evaluate the nailfold capillary morphological features in patients with exfoliative glaucoma (XFG) and compare them with those pertaining to primary open-angle glaucoma (POAG), normal controls and subjects with exfoliation syndrome (XFS). The second purpose was to investigate all parameters related to platelet function on the hemogram, including the platelet count (PLT), the mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT) in patients with XFG. These parameters were subsequently compared with those belonging to normal controls, POAG and XFS subjects. Methods This case control study involved 152 consecutive patients that were examined at the Glaucoma Department of Clinic for Eye Diseases, Clinical Centre of Serbia, as the referral center for glaucoma in Serbia, between June 2016 and December 2017. Results Regarding capillaroscopic characteristics, statistically significant difference was found in capillary diameter and tortuosity between the XFG and POAG group (p = 0.050 and p = 0.035) and the XFG and NC group (p = 0.003 and p = 0.044), as well as in the distribution of capillary loops and avascular zones between the XFG and NC group (p = 0.014 and p = 0.004). The subjects with XFG had lower PLT values compared to POAG patients (p = 0.022). Conclusions In conclusion, to the best of our knowledge, this study marks the first attempt to evaluate capillary morphology as well as to investigate all parameters related to platelet function on the hemogram, in patients with newly diagnosed XFG. Our findings revealed nailfold capillary morphological vascular changes in XFG patients. The subjects with XFG had lower PLT values and a higher MPV serum parameter compared to normal controls and patients with POAG. Further research in this field should therefore aim to evaluate the consequences of the aforementioned microvascular abnormalities in patients with XFG.

Yazgan S, Celik U, Ayar O, Ugurbas SH, Celik B, Akdemir MO, Ugurbas SC, Alpay A. The role of patient's systemic characteristics and plateletcrit in developing toxic anterior segment syndrome after uneventful phaco surgery: A case-control study. Int Ophthalmol 2018; 38:43-52. [PMID: 28130690 DOI: 10.1007/s10792-016-0418-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2015] [Accepted: 12/19/2016] [Indexed: 01/22/2023]
Abstract
PURPOSE To compare the systemic and ocular characteristics and laboratory findings of patients developing toxic anterior segment syndrome (TASS) after uneventful phaco surgery with unaffected subjects undergoing the same surgery in the same session. DESIGN A retrospective case-control study. METHODS The study group consisted of 26 eyes of 26 patients who underwent uneventful phaco surgery and who went on to develop TASS, while the control group included 39 subjects who had routine phaco surgery in the same session by the same surgeon. The sterilization stages of reusable instruments, disposable instruments, and compositions were recorded. The preoperative systemic diseases, complete blood count parameters, glycosylated hemoglobin (HbA1c), biochemical parameters, thyroid hormone profiles, and the surgical features were compared between the two groups. RESULTS Type 2 diabetes mellitus (DM), systemic hypertension (HT), hyperlipidemia, chronic ischaemic heart disease, and chronic renal failure were significantly more common in the TASS group (p < 0.05). Proliferative diabetic retinopathy was also more frequent in the TASS group (p = 0.003). Mean HbA1c% values, white blood cell count, neutrophil/lymphocyte ratio, platelet counts, platelet distribution width, and plateletcrit parameters were significantly higher in the TASS group (p < 0.05). Multivariate logistic regression analysis revealed that a high plateletcrit level (p = 0.001, odds ratio [95% CI]; 22.27 [3.36-147.76]) and systemic HT (p = 0.044, odds ratio [95% CI]; 7.13 [1.05-48.12]) are independently associated with the development of TASS. CONCLUSION Although TASS may arise as a result of insufficient sterilization of instruments or intraocular solutions, patient factors may also contribute to its development. Systemic vascular disorders such as uncontrolled type 2 DM, systemic hypertension, and hyperlipidemia may increase the risk of TASS after uneventful phaco surgery. Abnormal parameters associated with systemic inflammation, such as higher plateletcrit level, may facilitate the development of TASS. These findings may be a predicting factor of TASS development for uneventful cataract surgeries.

Abstract
Purpose Retinal vein occlusion (RVO) and diabetic retinopathy (DR) are two major sight-threatening diseases which may lead to neovascular glaucoma (NVG). The aim of this study was to explore the association between platelet parameters and NVG. Methods A total of 185 subjects were enrolled for the study from January, 2012 to December, 2015 at the Eye-ENT Hospital of Fudan University. Patients include those with NVG secondary to RVO (RVO group, n = 38), patients with NVG secondary to DR (DR group, n = 47), diabetics mellitus without retinopathy (DM group, n = 52), and healthy individuals (control group, n = 48). A complete ophthalmological examination including visual field examination, A-scan ultrasound, Fundus photography, and measurement of platelet parameters were performed for NVG subjects. Results There was no statistical difference in the mean age and gender among the RVO, DR, and control groups (p>0.05). The mean level of platelet distribution width (PDW) was higher (p<0.001) in the RVO group (15.16±2.13fl) and DR group (16.17±1.66fl) when compared with the control group (13.77±2.99fl). The mean plateletcrit (PCT) value of the RVO group (0.229±0.063%) was also higher (p = 0.049) than the control group (0.199±0.045). In the DR group, mean platelet volume (MPV) value (10.72±1.57fl) was significantly higher (p = 0.002) than the control group (9.75±0.89fl). A similar trend was observed when platelet parameters were compared among the 3 groups with respect to age. The mean level of PDW was significantly higher (p<0.001) in the DR group (16.17±1.66fl) compared with the DM group (13.80±3.32fl). Stepwise multiple logistic regression analysis revealed that PDW (OR = 1.44, 95%CI = 1.149–1.805, p = 0.002) and MPV (OR = 1.503, 95%CI = 1.031–2.192, p = 0.034) were associated with the DR group, PDW (OR = 1.207, 95%CI = 1.010–1.443, p = 0.039) and PCT (OR = 1.663, 95%CI = 1.870–2.654, p = 0.036) were associated with the RVO group. Conclusion Our results suggest that increased PDW and MPV are associated with the NVG secondary to DR group, elevated PDW and PCT are associated with the RVO group. It indicates that platelets might be an important factor in the onset and/or development of NVG.

Int Ophthalmol 2016; 37:119-124.

Abstract
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.
