Abstract
PURPOSE The study aimed to analyze the surgical outcome of manual small incision cataract surgery (MSICS) in patients with pseudoexfoliation syndrome (PXF) and pseudoexfoliation glaucoma (PXG) and compare them with those of controls. SETTINGS AND DESIGN This prospective, observational, and comparative study included 150 cases of PXF with cataracts, 150 cases of PXG with cataracts, and 200 cases of cataracts without PXF as controls. METHODS MSICS was performed in all cases under peribulbar anesthesia. Intraoperative complications, if any, were noted. Best-corrected visual acuity (BCVA), intraocular pressure (IOP), and postoperative complications were recorded at follow-up on day 1, day 7, and after 1 month. STATISTICAL ANALYSIS USED IBM SPSS 24.0 statistics, SPSS South Asia Pvt Ltd. RESULTS Lines of improvement in BCVA were significantly better in the control group (8.7 ± 1.7) than that in the PXF (7.5 ± 2.1) and PXG groups (6.4 ± 2.7). IOP significantly decreased from baseline to 1 month postoperatively in the PXG group than in the PXF and control groups (mean difference: 3.8 ± 7.5 mm Hg). Intraoperative iridodialysis and zonular dialysis were significantly high in the PXG group with a proportion of 4 and 20%, respectively. Postoperative choroidal detachment and hyphema, six cases each, were found significantly high in the PXG group. CONCLUSION Although the BCVA improvement was less and the complications were high in patients with pseudoexfoliation, especially those with PXG, the reduction in IOP was significant. MSICS can be considered favorably in patients with PXF and PXG, with adequate precautions to manage anticipated complications.

Swept Source Optical Coherence Tomography Analysis of a Selected Eye's Anterior Segment Parameters in Patients with Pseudoexfoliation Syndrome. J Clin Med 2022; 11:jcm11010268. [PMID: 35012009 PMCID: PMC8745779 DOI: 10.3390/jcm11010268] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 12/26/2021] [Accepted: 12/31/2021] [Indexed: 02/04/2023] Open
Abstract
Background: Pseudoexfoliation syndrome (PEX) is a systemic, age-related disorder characterized by the production and accumulation of pseudoexfoliation material. To date, detailed characteristics have not been published regarding the iridocorneal angle and cornea in patients with pseudoexfoliation syndrome determined through swept source optical coherence tomography (SS-OCT). Methods: A total of 150 eyes of patients with pseudoexfoliation syndrome (ages 69–86 years) and 166 eyes in a control group (ages 54–79 years) were analyzed. Results: The central corneal thickness in the PEX group was 549.56 μm and was slightly (insignificantly) higher than that of the control group (540.56 µm). The anterior chamber of the eye was visibly shallower in patients with PEX syndrome than in those of the control group (2.49 mm vs. 3.07 mm; p < 0.001). The Fourier analysis parameters of the cornea showed multiple differences between the PEX and control groups. With respect to iris area, the parameters showed statistically significant differences between the PEX and control groups in all four quadrants of the eye. No statistical significance was found in the PEX group for the iridocorneal angle parameters, or corneal and lens parameters depending on gender and age. Conclusions: PEX syndrome is characterized by a significant impact on the anterior eye segment, including higher anterior and posterior keratometric values, lower anterior chamber depth, higher iris thickness, and narrower angle parameters. The characteristic anterior eye segment features of PEX syndrome can be detected using SS-OCT, which could potentially assist clinicians in properly managing the disease.

Abstract
Pseudoexfoliation syndrome (PEXS) and glaucoma (PEXG) are assumed to be caused by a generalized elastosis leading to the accumulation of PEX material in ocular as well as in extraocular tissues. The exact pathophysiology of PEXS is still elusive. PEXG, the most common type of secondary open-angle glaucoma (OAG), is characterized by large peaks of intraocular pressure (IOP) with a progressive loss of the visual field. Agonistic autoantibodies (agAAbs) against the β2-adrenergic receptor (AR) have been shown to be present in sera of patients with primary and secondary OAG and ocular hypertension and are seemingly linked to IOP. In the present study, we investigated the autoantibodies directed against the β2-AR in sera of patients with PEXS and PEXG. We recruited 15, 10, and 15 patients with PEXG, PEXS, and primary OAG, respectively. Ten healthy individuals served as controls. All patients underwent standard ophthalmological examination with Octopus G1 perimetry. agAAbs prepared from serum samples were analyzed in a rat cardiomyocyte-based bioassay for the presence of agAAbs. We identified the interacting loop of the β2-AR and the immunoglobulin G (IgG) subclasses using synthetic peptides corresponding to the extracellular loops of the receptors and enzyme-linked immunosorbent assay, respectively. None of the controls were β2-agAAb-positive (0.2 ± 0.5 U). No β2-agAAbs (0.2 ± 0.4 U), but inhibitory β2-AAbs were observed in 80% of the patients that partially blocked the drug-induced β2-adrenergic stimulation; 5.8 ± 1.7 U vs. 11.1 ± 0.9 U for clenbuterol in the absence and the presence of sera from patients with PEXS, respectively. Epitope analyses identified the third extracellular loop of the β2-AR as the target of the inhibitory β2-AAbs, being of IgG3 subtype in PEXS patients. In contrast, patients with PEXG showed β2-agAAbs (5.6 ± 0.9 U), but no inhibitory ones. The β2-agAAbs levels of patients with PEXG and primary OAG patients (3.9 ± 2.8 U; p > 0.05) were at a similar level. In two cases of PEXG, the β2-agAAbs exert synergistic effects with clenbuterol. The activity increased from 11.5 ± 0.3 (clenbuterol only) to 16.3 ± 0.9 U. As autoimmune mechanisms were reportedly involved in the pathogenesis of glaucoma, agonistic and inhibitory β2-AAbs seem to be a part of this multifactorial interplay.

Abstract
BACKGROUND To evaluate vitreoretinal interface abnormalities in patients with pseudoexfoliation (PEX) syndrome. METHODS This case-control study was performed in 136 patients diagnosed with unilateral PEX (PEX group) and 139 age- and sex-matched healthy volunteers (Control group). Both the affected and contralateral eyes were evaluated in the PEX group and the right eye was evaluated in the Control group. Vitreoretinal interface abnormalities and posterior vitreous detachment (PVD) were evaluated on optical coherence tomography (OCT) examination. RESULTS The incidences of incomplete and complete PVD were significantly higher in the affected than contralateral eye in the PEX group and in the right eye in the Control group (P = 0.009, P = 0.012 and P = 0.004, P = 0.017, respectively). The rates of 'no PVD' were significantly higher in the contralateral eye in the PEX group and the Control group compared to the affected eye in the PEX group (P = 0.003 and P = 0.001, respectively). The odds ratio for incomplete PVD was 3.1 in PEX eyes compared to the contralateral eye in the PEX group and 3.9 compared to the Control group. The rate of epiretinal membranes (ERMs) in the affected eye was significantly different from the contralateral eye in the PEX and Control groups (P < 0.001 and P < 0.001, respectively). The odds ratio for ERM in PEX eyes was 3.51 compared to the contralateral eye in the PEX group and 4.23 compared to the Control group. In the presence of incomplete PVD, the odds ratio for ERM development was 3.81 in PEX eyes. CONCLUSIONS We detected high rates of ERMs and incomplete PVD in patients with PEX. It is important to evaluate and follow up PEX cases in terms of vitreoretinal interface abnormalities.

Abstract
Purpose To compare the effective lens position (ELP), anterior chamber depth (ACD) changes, and visual outcomes in patients with and without pseudoexfoliation syndrome (PEX) after cataract surgery. Design Prospective, randomized, fellow-eye controlled clinical case series. Methods This prospective comparative case series enrolled 56 eyes of 56 consecutive patients with (n = 28) or without PEX (n = 28) and clinically significant cataract who underwent standard phacoemulsification and were implanted with single-piece acrylic posterior chamber intraocular lenses (IOLs). The primary outcome parameters were the ACD referring to the distance between the corneal anterior surface and the lens anterior surface, which is an indicator of the postoperative axial position of the IOL (the so-called ELP) and distance corrected visual acuity (DCVA). Results Before surgery, the ACD was 2.54 ± 0.42 mm in the PEX group and 2.53 ± 0.38 mm in the control group (p = 0.941). Postoperatively, the ACD was 4.29 ± 0.71 mm in the PEX group and 4.33 ± 0.72 mm in the normal group, respectively (p = 0.533). There was no significant difference in ACD changes between groups (PEX group: 1.75 ± 0.74 mm, control group: 1.81 ± 0.61 mm, p = 0.806) and DCVA pre- (p = 0.469) and postoperatively (PEX group: 0.11 ± 0.13 logMAR, control group: 0.09 ± 0.17 logMAR, p = 0.245) between groups. Conclusion Preoperative and postoperative ACD, as an indicator of ELP, between PEX eyes and healthy eyes after cataract surgery showed no significant difference. Phacoemulsification induced similar changes in eyes with PEX compared to healthy eyes.

Abstract
PURPOSE: To compare the postoperative alteration of central corneal thickness (CCT) and visual outcomes between phacoemulsification (group A) and manual small incision cataract surgery (MSICS) (group B) in grade II and III nuclear cataracts (NS II and III) with pseudoexfoliation syndrome (PXF). METHODS: It is a double masked prospective randomised interventional study. A total of 60 eyes of 60 patients were assigned randomly to either the phacoemulsification (group A) or MSICS (group B) groups. All eyes had nuclear sclerosis grade II and III (LOCS II grading system) with pseudoexfoliation material either over the pupillary margin, anterior lens capsule, or both. All surgeries were done by a single surgeon. Postoperative evaluation was scheduled on the 1st, 30th, 90th, and 180th-day. Statistical analyses were done using appropriate methods. Outcome of the study were measured with changes in central corneal thickness (CCT), Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA) and the spherical equivalent in the operated eye up to 6 months post surgery. RESULTS: The mean preoperative CCT showed no difference between the groups (0.9659). The mean rise in CCT on the 1st postoperative day (POD) showed a significant difference between the groups {24.65 (SD 9.32) [group A (Phacoemulsification)] and 33.34 (SD11.68) [group B (MSICS)] (P < 0.0023)}. At the 1st, 3rd, and 6th month postoperative visits, there was no significant difference. The mean uncorrected distance visual acuity (UDVA) on the 1st POD was 0.189 (SD 0.118) in Group A and 0.302 (SD 0.121) in group B (P < 0.0005) which was significantly better with the phacoemulsification procedure. At the 1st month it was 0.039 (SD 0.084) in group A and 0.148 (SD 0.089) in group B (P < 0.004), which remained almost stable after that. The mean corrected distance visual acuity (CDVA) at the 1st, 3rd, and 6th-month postoperative visits showed no significant difference (P 0.8). The mean spherical equivalent was 0.29 in group A and 0.8 in group B. CONCLUSION: In moderately hard nuclear cataracts with PXF, phacoemulsification provides better unaided visual outcomes with less endothelial dysfunction than MSICS in the immediate and subsequent postoperative period.

Abstract
OBJECTIVES Evaluation of atherogenic indices in patients with pseudoexfoliation syndrome (PEXS) by traditional serum lipid profiles [total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c) and non-HDL-c] and non-traditional serum lipid ratios [TC/HDL-c, TG/HDL-c, LDL-c/HDL-c and non-HDL-c/HDL-c]. METHODS A total of 100 patients were included in the study. Fifty patients diagnosed with PEXS were regarded as group 1 and 50 patients without PEXS were regarded as group 2, respectively. RESULTS The median TC, TG, LDL-c, HDL-c and non-HDL-c values were significantly higher in group 1 compared to group 2 (p = 0.007, p = 0.025, p = 0.016, p = 0.015 and p = 0.042, respectively). But there were no significant differences in the TC/HDL-c, TG/HDL-c, LDL-c/HDL-c and non-HDL-c/HDL-c ratios among the two groups (p = 0.581, p = 0.617, p = 0.292 and p = 0.583, respectively). CONCLUSIONS Non-traditional serum lipid ratios are superior to traditional serum lipid profiles for identifying the risk of vascular disease and this study did not demonstrate a complete relationship between PEXS and increased risk of vascular disease.

Abstract
Objective: To investigate whether serum vitamin D levels have an effect on
pseudoexfoliation (PEX) glaucoma/syndrome development and on the control of glaucoma in these
cases.
</P><P>
Method: A total of 31 cases with PEX glaucoma, 34 cases with the PEX syndrome and 43 control
subjects of similar age and sex were included in the study. Vitamin D levels were compared between
the groups and also between the cases where glaucoma surgery was performed or not.
Results:
PEX glaucoma group consisted of 17 males and 14 females, PEX syndrome group of 27
males and 7 females, and the control group of 27 males and 16 females. The mean age was 70.9±8.9
years, 72.1±7.3 years, and 67.9±9.1 years in PEX glaucoma, syndrome and control group, respectively.
Mean vitamin D levels were 9.4±7.7 ng/mL, 7.9±6,1 ng/mL, 11.5±14.2 ng/mL in PEX glaucoma, syndrome
and control group, respectively (p>0.05). The mean serum vitamin D level was 8.04±4.7 ng/mL
in those who underwent glaucoma surgery and 10.1±8.7 ng/mL in those who didn't undergo glaucoma
surgery in PEX glaucoma group (p>0.05). No difference was found between the PEX glaucoma subgroups
in terms of the mean deviation when classified according to vitamin D levels (<10 ng/mL, ≥10
ng/mL) (p>0.05).
Conclusion:
Although we found no statistically significant difference between the PEX syndrome/
glaucoma, and control group in terms of serum vitamin D levels, serum vitamin D levels were
lower in PEX syndrome and glaucoma group than control group. Our results indicate that serum vitamin
D levels have no effect on the development of PEX glaucoma/syndrome or the control of the disorder
in cases with PEX glaucoma. However, these results need to be supported with further studies on
a larger number of patients and with longer follow-up.

Abstract
PurposeTo investigate the relationship between serum neutrophil/lymphocyte ratio and pseudoexfoliation syndrome.Materials and methodsThis study was designed as a retrospective analysis. Patients were divided into three groups: 55 patients with pseudoexfoliation syndrome (group 1), 19 patients with pseudoexfoliation glaucoma (group 2), and 48 control subjects without pseudoexfoliation syndrome or pseudoexfoliation glaucoma (group 3). The levels of neutrophils and lymphocytes were measured by ABX Pentra DF120/USA biochemical analyzer. The neutrophil/lymphocyte ratio was measured by dividing neutrophil count by lymphocyte count.ResultsThe mean ages of patients were 67.9±8.1 in group 1, 70.6±7.4 in group 2, and 67.3±7.6 in group 3 (P=0.172). Baseline clinical characteristics, such as diabetes and hypertension, were similar among groups. The mean neutrophil/lymphocyte ratio values were 2.08±0.61 in group 1, 2.20±0.58 in group 2, and 1.51±0.57 in group 3. The neutrophil/lymphocyte ratio was significantly higher in group 1 and 2 than the group 3 (P<0.001). In receiver operating characteristics analysis, the area under the curve for neutrophil/lymphocyte ratio was 0.776, and a neutrophil/lymphocyte ratio of >1.72 predicted pseudoexfoliation syndrome with a sensitivity of 77% and specificity of 71%.ConclusionThe elevated neutrophil/lymphocyte ratio is significantly associated with pseudoexfoliation syndrome. This novel and low-cost parameter can provide useful information for the relevant risk evaluation in these patients.

Abstract
AIM To examine the mechanism of the development of pseudoexfoliation (PSX) syndrome via both cytokine formation and endothelial vasorelaxing and growth factors that will provide us new therapeutic insights for the treatment. METHODS This is a cross sectional study included two groups; Group 1: control patients with nuclear cataract (n=20, aged 51-80 years). Group 2: PSX patients with nuclear cataract (n=18, aged 50-90 years). Patients with other ophthalmic problems and systemic diseases were excluded. Vascular endothelial growth factor (VEGF), interleukin-6 (IL-6) and interleukin-1β (IL-1β) and nitrotyrosine levels were determined through serum samples by Enzyme-linked immunosorbent assay (ELISA) method. Nitrite-nitrate levels were measured with photometric endpoint determination. RESULTS There were no significant differences between the groups in terms of age, VEGF, IL-1β, nitrite-nitrate and nitrotyrosine. The significant results were the mean IL-6 levels that were higher in PSX group 2 (37.68±29.52 pg/mL) compared to that in control group 1 (15.32±10.08 pg/mL) (P<0.001). CONCLUSION Several interacting and extending biochemical pathways may lead to the promotion of VEGF and IL-6 expressions. IL-6 which is the only altered marker in our study may indirectly cause an increase of vascular permeability and neovascularization. We suggest inflammation as a factor that can be involved in etiopathogenesis of PSX.
