Long term outcome and prognostic indicators in Posner Schlossman syndrome.

BACKGROUND: Posner Schlossman syndrome is a well-defined uveitis entity that is characterised by relapsing remitting unilateral anterior uveitis with markedly raised intraocular pressure. The aim of this study was to determine the risk factors for progression in patients with Posner Schlossman syndrome. METHODS: Ninety-eight patients were enrolled in a retrospective case series. Progression was defined as a composite endpoint of any of development of permanent glaucoma (in patients with no evidence of glaucomatous loss on presentation), corneal failure, or chronic inflammation. Relapse was defined as a resolving episode of inflammation not meeting the criteria for progression. RESULTS: Seventy seven percent of patients relapsed on average each 2.2 years. Forty percent of patients progressed. On univariate analysis, increased age at enrolment, immunocompromise at enrolment, the presence of glaucomatous optic neuropathy at enrolment, the performance of an anterior chamber tap and a positive anterior chamber tap were all associated with increased risk of progression. On multivariate analysis, age at enrolment, immunocompromise at enrolment, the performance of an anterior chamber tap, and the presence of glaucomatous optic neuropathy at enrolment were independently associated with increased risk of disease progression. CONCLUSIONS: Posner Schlossman syndrome is not a benign uveitis entity and risk of both relapse and progression are high. Older patients, immunocompromised patients, patients with glaucomatous optic neuropathy at enrolment and those with a positive anterior chamber tap are all at increased risk of progression.

The Incidence and Risk Factors of Optic Nerve Damage of Posner-Schlossman Syndrome: A Meta-Analysis.

Objective: To explore the incidence and associated factors of glaucoma optic nerve damage (GOND) among patients with Posner-Schlossman syndrome. Methods: We retrieved relative studies till July 2022 using databases including PubMed, CNKI, VIP, and Wan-Fang. The retrieval terms include "Posner-Schlossman syndrome", "Glaucomatocyclitic Crisis", and "visual field". The Chinese retrieval terms were the corresponding Chinese terminologies for the English terms mentioned above. The outcomes were the incidence of GOND among PSS patients, the male proportion, patient age, the proportion of patients with single eye affected, disease duration, and intraocular pressure during the episode in patients with or without GOND. Review manager 5.3 was used for the analysis. Results: In total, 19 studies were included in our analysis. The pooled incidence of GOND among PSS patients was 0.26 (95% CI = 0.16-0.43). Age [MD = 11.3(5.86, 16.73); P < .0001], disease duration [MD = 4.27 (3.38, 5.16), P < .00001], and single or double eye affected [RR = 0.69 (0.49, 0.98), P = .04] were significantly associated with the development of GOND. Whereas, gender [RR = 1.09 (0.91, 1.29), P = .35] and intraocular pressure at episodes [MD = 2.66 (-0.38, 5.7), P = .09] were not significantly associated with GOND development. Conclusion: A fraction of PSS patients ultimately develop GOND so physicians should not be highly optimistic about the prognosis of PSS patients and timely and effective treatment is very important. Patients of higher age, those with double eyes affected, and suffering from a long disease duration might be at a greater risk of developing GOND.

Comparison of retinal and choroidal changes in Fuchs' uveitis syndrome.

PURPOSE: The assessment of retinal and choroidal changes in eyes with unilateral Fuchs uveitis syndrome (FUS) with the fellow eye and healthy control group. METHODS: Thirty-nine unilateral FUS patients and 42 healthy control subjects were enrolled. Spectralis domain optical coherence tomography (SD-OCT, Spectralis; Heidelberg Engineering GmbH, Heidelberg, Germany) was used to evaluate retinal and choroidal structures. Retinal and choroidal thicknesses were recorded from OCT images. Choroidal images were binarized to calculate choroidal vascularity index (CVI) with ImageJ 1.52 s (National Institutes of Health, Bethesda, MD, USA) program. RESULTS: CVI was found to be significantly lower in the FUS group compared to the fellow eyes and healthy control groups (p = 0.039 and p = 0.046, respectively). There was no significant difference in central choroidal thickness in the FUS group compared to the fellow eyes and control groups (p = 0.552 and p = 0.321, respectively). There was no statistically significant difference between the 3 groups in terms of macular thickness in all quadrants (p > 0.05 for all quadrants). CONCLUSIONS: Affected eyes tend to decrease in CVI, while there is no difference in retinal and central choroidal thicknesses in patients with FUS compared to eyes of other unaffected eyes and healthy individuals. It may be because the chronic inflammation associated with the disease affects the vascular structure of the choroid.

Prognostic factors of cataract surgery in patients with uveitis.

PURPOSE: To evaluate the long-term visual outcomes of patients with uveitis undergoing cataract surgery and to identify possible factors influencing the visual prognosis and the development of postoperative complications. METHODS: Retrospective study of all patients with uveitis who underwent cataract surgery between January 2015 and February 2020 in our tertiary referral center. RESULTS: A total of 78 eyes from 78 patients were included in the study. The best-corrected visual acuity (BCVA) improved in 86% of patients, and a BCVA of 0.5 or better was achieved in 57 (73%) patients. A significant correlation was shown between the preoperative and postoperative BCVA (Spearman r = 0.521, p < 0.01). Final BCVA differed between diverse anatomical uveitis entities (p = 0.047), and anterior uveitis demonstrated the best outcomes. Chronic uveitis resulted in a worse final BCVA than acute recurrent uveitis (p = 0.001). The presence of CME any time before the surgery and intermediate uveitis were associated with worse visual prognosis, while systemic therapy for uveitis before surgery and iris manipulation during surgery were not related to visual outcomes. Postoperative development of cystoid macular edema (CME) was closely associated with preexisting CME (p < 0.001) and intermediate uveitis (p = 0.01). CONCLUSIONS: Visual results of cataract surgery in patients with uveitis were beneficial, but limited visual outcomes were more frequently observed in patients with chronic uveitis and intermediate uveitis with a history of CME. In consequence, prevention, or adequate treatment of CME, especially in patients with intermediate uveitis, might result in better visual results of their cataract surgery.

Rejuvenating the aging upper periorbita.

PURPOSE: To investigate the efficacy of a comprehensive surgical approach in rejuvenating the aging upper periorbita. METHODS: Three hundred and twenty eyes of 160 patients who were treated for dermatochalasis(D), eyebrow ptosis (EP) and blepharoptosis (BP) were included in the study. One hundred and ninety-eight patients had only dermatochalasis, 74 patients had D and EP, 39 patients had D and BP, 7 patients had D, EP and BP and 2 patients had D, EP and blepharospasm. The patients were evaluated before surgery, at 1 week, 1 month and 6 months after surgery. Dermatochalasis was scored between 0 and 3 points according to upper lid laxity and IP drooping. EP was scored between 0 and 2 points as normal, lateral EP and total EP. Aging was classified as mild in those with a total score of less than 3 points, moderate in those with a score of 3-6 and severe in those above 6 points. RESULTS: Of the patients, 121 were female and 39 were male, with a mean age of 52 (40-87) years. The surgeries were performed as follows: upper eyelid blepharoplasty (UEB) 197(61.6%) patients, UEB + browpexy(B) 77(24.1%) patients, UEB + B + levator resection(LR) 7(2.2%) and UEB + LR 39 (12.2%) patients. While a statistically significant improvement was observed in patients who underwent UEB + B (p < 0.001), postoperative improvements were not found statistically significant compared to preoperative scores in other surgeries. The postsurgical scores showed statistically significant improvement in all age groups (p < 0.001). CONCLUSIONS: A comprehensive surgical treatment can provide effective results in upper periorbital rejuvenation for patients with varying degrees of upper periorbital aging.

Optic coherence tomography angiography findings in fuchs heterochromic iridocyclitis.

PURPOSE: To evaluate macular capillary perfusion in patients with fuchs heterochromic iridocyclitis (FHI) by using optical coherence tomography angiography (OCTA). MATERIAL AND METHOD: A total of 19 eyes of 19 patients with unilateral FHI underwent detailed eye examination. OCTA (RTVue-XR Avanti) images were obtained from both eyes. OCTA parameters, including foveal avascular zone, superficial capillary plexus and deep capillary plexus vessel densities, were compared between the involved and fellow control eyes. RESULTS: The median age of the patients (11 females, 8 males) was 42.0 ± 9.63 (range 24-57) years. DCP and SCP densities at the parafoveal and perifoveal area were significantly lower in the FHI eyes compared to the control eyes (44.80 ± 5.24% vs. 54.70 ± 3.76% and 43.30 ± 5.10% vs. 53.70 ± 2.73%, respectively; p < 0.05). The median FAZ was 0.29 ± 0.12 (0.11-0.42) mm2 in the FHI eyes and 0.26 ± 0.09 (0.10-0.40) mm2 in the control eyes. This difference did not reach statistical significance (p = 0.199). CONCLUSION: Macular capillary perfusion was significantly reduced in both SCP and DCP in the eyes with FHI. FHI, which is known to affect the choroid layer, could also compromise macular capillary perfusion of the retina.

Anterior segment structures in dark iris Chinese patients with unilateral Fuchs' uveitis syndrome.

PURPOSE: To compare binocular anterior segment structures in Chinese patients with dark iris and unilateral Fuchs' uveitis syndrome (FUS). METHODS: This was a cross-sectional study including 34 phakic eyes (17 patients) with unilateral FUS. Anterior segment parameters were measured by rotating Scheimpflug imaging camera, noncontact specular microscopy, and anterior segment optical coherence tomography. RESULTS: Corneal volume was higher in FUS eyes compared to unaffected eyes (p < 0.05). The iridocorneal angles were larger in FUS eyes compared to contralateral eyes (p < 0.05). Mean endothelial cell density (ECD) was lower, and the coefficient of variation in endothelial cell size and average cell area of endothelial cells (ACA) were higher, in FUS eyes (p < 0.05). Mean densitometry values of the midstromal cornea (zones with a diameter of 0-2, 2-6, or 10-12 mm), posterior (0-2, 2-6, 10-12, or 0-12 mm), or total thickness (0-2 or 2-6 mm) were higher in FUS eyes compared with unaffected eyes (p < 0.05). ECD, percentage of hexagonal cells, and ACA were strongly related to densitometry values of the midstromal and posterior cornea in the FUS eyes (p < 0.05). Smoothness index of iris was lager in affected eyes (p < 0.05). CONCLUSION: In Chinese patients with unilateral FUS, loss of endothelial cells, wider iridocorneal angle, thicker cornea, higher corneal densitometry of midstromal and posterior layer, and smoother iris were observed in affected eyes compared to contralateral eyes. These data can help to elucidate anterior segment characteristics of unilateral FUS in this population.

[Chinese expert consensus on the clinical diagnosis and treatment of Fuchs uveitis syndrome].

Fuchs uveitis syndrome is a chronic, non-granulomatous, and unilateral anterior uveitis. It is one of the most under-diagnosed or misdiagnosed uveitis entities. A number of factors are involved in its etiology, which has not been completely understood. Misdiagnosis of this disease may result in over-treatment and facilitate the development of complicated cataract and secondary glaucoma. An extensive investigation and literature review on this disease have been performed by the experts in the Ocular Immunology Group of Ophthalmology Society of Chinese Medical Association and the Uveitis and Ocular Immunology Group of Chinese Ophthalmologist Association. Consensus opinions on Fuchs uveitis syndrome have been developed in an attempt to provide general guidance and reference in the diagnosis and treatment of this disease.

May ganglion cell complex analysis be a marker for glaucoma susceptibility in unilateral Fuchs' uveitis syndrome?

PURPOSE: To compare retinal nerve fiber layer (RNFL) thickness and ganglion cell-inner plexiform layer thickness (GCIPLT) in the affected eyes to fellow unaffected eyes of patients with unilateral Fuchs' uveitis syndrome (FUS) and analyze their change over time. METHODS: Twenty seven unilateral FUS patients who did not have concomitant systemic or ocular disease were retrospectively enrolled. Central macular thickness (CMT), RNFL thickness, and GCIPLT measurements were evaluated. Data was analyzed using the non-parametric Brunner-Langer model (LD-F2 design) and Wilcoxon signed-rank test. RESULTS: The mean age of the patients was 40.2 ± 10.2 years. The median disease duration was 11 (2-62) months. The median best-corrected visual acuity (BCVA) of the affected eyes and the fellow eyes was 0.22 (0.00-2.50) vs. 0.00 (0.0-0.10) logMAR at the initial visit and 0.05 (0.00-2.50) vs. 0.00 (0.0-0.30) logMAR at the final visit. The change in BCVA was found significant in the affected eyes, but not in the fellow eyes (p < 0.001 and p = 0.287, respectively). The median CMT in the affected eyes at the final visit was not statistically different from the value at the initial visit (255 (157-306) vs. 245 (140-310) µm, p = 0.256). The change in RNFL thickness over time in the affected eyes was similar to the fellow unaffected eyes of the patients with unilateral FUS at all quadrants, with non-significant time and group effects (p > 0.05). However, median GCIPLT in all quadrants (except superonasal) in the affected eyes was statistically lower than the fellow eyes at the initial and final visits (p < 0.05). The most affected quadrant of the ganglion cell complex was inferonasal in the involved eyes (79 (42-97) vs. 75 (43-87) µm) at initial and final visits (p = 0.033 for time effect and p < 0.001 for group effect, respectively). CONCLUSION: Median CMT and RNFL thickness did not change during follow-up in the affected eyes of patients with unilateral FUS. Median GCIPLT in the affected eyes declined over time in all quadrants. Ganglion cell loss was also most prominent in the inferonasal quadrant in the affected eyes. FUS patients should be followed up long-term in terms of ganglion cell loss, especially in the inferonasal quadrant.

Aetiology and clinical characteristics of uveitic glaucoma in Turkish patients.

PURPOSE: To investigate the types, frequency and clinical profiles of uveitic glaucoma seen at a tertiary care center and also to have an idea about the distribution of uveitic glaucoma types in Turkish population. METHODS: Consecutive case notes of all patients attending a specialized uveitis clinic over a 3-month period were reviewed retrospectively. RESULTS: One hundred and seven eyes of 96 patients were included. Sixty-five of the eyes had anterior, one intermediate, nine posterior uveitis while 32 of them had panuveitis. Twenty-three eyes had acute, 52 chronic and 32 recurrent uveitis. Herpes virus associated iridocyclitis was the leading cause of anterior uveitis-associated uveitic glaucoma followed by cytomegalovirus (CMV) associated anterior uveitis; while steroid-induced glaucoma accounted for the majority of chronic uveitis with glaucoma followed by Fuchs' uveitis syndrome (FUS). The most common causes of glaucoma among the cases were steroid-induced in 30 eyes (28%), Herpes virus anterior uveitis in 24 eyes (22%), CMV anterior uveitis in 20 eyes (18%), FUS in 15 eyes (14%), ocular toxoplasmosis in 5 eyes (4%). Behçet's uveitis was the most common (n = 11, 36%) cause of steroid-induced glaucoma. The need for surgical intervention was 23.32% (n = 25; 12 of them were FUS, 8 steroid-dependent, 1 HSV and 3 CMV anterior uveitis and 1 angle closure glaucoma with idiopathic uveitis) in our cases. CONCLUSION: Uveitic glaucoma is a common complication in a tertiary clinic. The most common causes are steroid-induced, FUS, viral anterior uveitis. The most common disease causing steroid induced glaucoma was Behçet's disease. Glaucoma surgery is required in a significant number of cases.

INTRAOCULAR PRESSURE OUTCOMES AFTER SURGERY FOR RHEGMATOGENOUS RETINAL DETACHMENT IN SCHWARTZ SYNDROME.

PURPOSE: To study intraocular pressure (IOP) outcomes after surgery for rhegmatogenous retinal detachment in Schwartz syndrome. METHODS: We reviewed records of 32 eyes of 32 patients with Schwartz syndrome (patients with rhegmatogenous retinal detachment, IOP above 21 mmHg, and open angles without angle recession, chronic steroid use or other secondary causes of increased IOP) who had undergone surgical treatment consisting of scleral buckling or vitrectomy. Intraocular pressure, number of medication, best-corrected visual acuity were compared at baseline and postsurgery visits and also studied association of various factors on long-term IOP. RESULTS: The median duration of rhegmatogenous retinal detachment was 2 months, and the inter quartile range was 1 to 12 months. Follow-up was 15 months (inter quartile range: 7-33 months). Sixteen (50%) had prior ocular trauma. Baseline IOP was 35 ± 8 mmHg, and 12% (4/32) of patients were on IOP-lowering medication at presentation. At the final visit, mean IOP was 17 ± 6 mmHg and 59% patients (19/32) required additional IOP-lowering medication or surgery for IOP control. CONCLUSION: Surgical management of rhegmatogenous retinal detachment resulted in significant reduction in IOP. At the final visit, 41% did not require any IOP-lowering medication or surgical intervention for IOP control.

The outcome of initial mitomycin C-augmented trabeculectomy with subconjunctival bevacizumab in the management of secondary glaucoma associated with Fuchs heterochromic iridocyclitis.

PURPOSE: To investigate the outcome of mitomycin C (MMC)-augmented trabeculectomy with subconjunctival bevacizumab in the management of Fuchs heterochromic iridocyclitis (FHI)-related glaucoma in 1-year follow-up period. METHODS: This retrospective study included 50 eyes with FHI-related glaucoma those had underwent initial trabeculectomy with MMC (0.2 mg/ml-3 min). Thirty-one of them had single-dose bevacizumab injection (1.25 mg/0.05 ml) into the bleb area just at the end of the surgery, while 19 eyes did not have. The intraocular pressure (IOP) and the mean number of anti-glaucomatous medications were evaluated. The IOP value ≤ 21 mmHg was defined as complete or qualified surgical success in terms of using medical anti-glaucomatous treatment. Bleb height and vascularity were evaluated with Indiana bleb grading system. Paired sample t test, t test, Chi-square and Kolmogorov-Smirnov tests were used for statistical analysis. RESULTS: The preoperative IOP values of bevacizumab and without bevacizumab groups were 32.8 ± 4.5 mmHg and 32.8 ± 4.5 mmHg, respectively, and they decreased to 17.5 ± 4.6 mmHg and 17 ± 5.2 mmHg at the final visit (p < 0.001 for all values). There were no significant differences in postoperative IOP and the number of medications between the groups at the final visit. In bevacizumab group, complete success was achieved in 100% within the third month but decreased to 22.5% (complete) and 74.1% (qualified) at the first year. In the other group (without bevacizumab group), complete success was achieved in 94.7% within the third month but decreased to 15.8% (complete) and 84.2% (qualified) at the first year. CONCLUSION: Initial trabeculectomy with MMC and subconjunctival bevacizumab injection was found to have lower rates of complete success with relatively acceptable qualified success rates in the management of FHI-related glaucoma. Subconjunctival bevacizumab was not found to have additional effect to improve the surgical success.

Choroid vascularity index as a parameter for chronicity of Fuchs' uveitis syndrome.

PURPOSE: This study aimed to compare the choroidal vascularity index (CVI) of eyes having Fuchs' uveitis syndrome (FUS) with healthy fellow eyes (N). METHODS: This prospective, cross-sectional study included unilateral FUS cases and an age- and gender-matched healthy control group. Thirty-nine participants were included in the FUS group, and 24 age- and gender-matched individuals were randomly selected for the control group. Endothelial cell density (ECD) was measured using Tomey specular microscopy. Spectral-domain optical coherence tomography was used to acquire the choroidal images, and binarization was applied to the images. Two blinded investigators analyzed the CVI in both eyes of the FUS cases and the right eyes of the healthy control group. RESULTS: CVI was found to be significantly decreased in FUS (p < 0.001). Additionally, ECD had a strong positive correlation with CVI (r = 0.383, p = 0.008). CONCLUSION: CVI may provide information about the chronicity of the disease.

Incidence of Immune-Mediated Inflammatory Diseases Among Patients With Inflammatory Bowel Diseases in Denmark.

BACKGROUND & AIMS: It is not clear whether the co-occurrence of immune-mediated inflammatory diseases (IMIDs) affects the course of inflammatory bowel diseases (IBD). We investigated the occurrence of IMIDs in relation to onset of IBD and the effects of concurrent IMIDs on IBD outcomes in a nationwide study of the Danish population. METHODS: We used a nationwide cohort of all individuals diagnosed with IBD, including Crohn's disease (CD) or ulcerative colitis (UC), in Denmark from 2007 through 2016 (n = 14,377). Patients were match with individuals without IBD from the general population (controls, n = 71,885). All cohort members were followed from birth until 2016, their migration, or their death. The occurrence of IMIDs was assessed using the Danish national patient register and Registry of Medicinal Products Statistics. RESULTS: A total of 3,235 patients with a diagnosis of IBD (22.5%) has also received a diagnosis of an IMID; most IMIDs occurred before the onset of IBD (n = 2,600, 80.3%). The most common IMIDs observed were psoriasis, asthma, type 1 diabetes, and iridocyclitis. Patients with IBD treated with infliximab were at reduced risk of developing IMIDs (CD adjusted odds ratio [aOR], 0.52; 95% CI, 0.34-0.81 and UC aOR, 0.47; 95% CI, 0.29-0.76). Co-occurrence of IMIDs increased the risk of surgery in patients with CD that developed IMIDs after CD onset (aOR, 2.30; 95% CI, 1.46-4.20) but not in UC. CONCLUSIONS: In a nationwide study of the Danish population, 22.5% of patients with IBD also had at least 1 concurrent IMID. Co-occurrence of IMIDs increased the risk of surgery in patients with CD.

Digital droplet polymerase chain reaction analysis of common viruses in the aqueous humour of patients with Posner-Schlossman syndrome in Chinese population.

BACKGROUND: To compare the detection results consistency of quantitative polymerase chain reaction (qPCR) and digital droplet polymerase chain reaction (ddPCR), and determine the value of ddPCR for viral detection in the aqueous humour. METHODS: A total of 130 aqueous humour samples were collected, including 60 patients with Posner-Schlossman syndrome (PSS) in case group and 70 elderly patients with senile cataract in control group. The target nucleic acid fragments of human cytomegalovirus (HCMV), herpes simplex virus, Epstein-Barr virus and varicella zoster virus in aqueous humour were analysed by qPCR and ddPCR, respectively, for the diagnosis and curative effect monitoring of pathogen-induced PSS. Samples with inconsistent results were verified by next-generation sequencing. RESULTS: There were 27 and 20 HCMV-positive cases detected in the case group by ddPCR and qPCR, respectively. ddPCR increased the sensitivity for the HCMV virus detection from 400 to 100 copies/mL. No other pathogens were found in this study. The results of ddPCR were consistent with that of next generation sequencing. The mean (SD) of Lg (HCMV copies/mL) detected by ddPCR and qPCR were 1.66 (1.92) and 1.10 (1.61), respectively (P < 0.001). Compared with qPCR, results of ddPCR showed better consistency with validity of clinical treatment. All patients with ddPCR-positive results had good validity on antiviral therapy, exhibiting anterior chamber inflammation remission, resolution of corneal oedema and good IOP control within 1 month. CONCLUSIONS: HCMV was the leading cause of pathogen-induced PSS in the Chinese population. ddPCR was a promising tool for early detection, accurate diagnosis and therapeutic validity monitoring of pathogen-induced PSS. The high sensitivity of ddPCR could avoid repeated anterior chamber tap.

The characteristic of intraocular pressure dynamic change in patients with glaucomatocyclitic crisis.

PURPOSE: To investigate the characteristic of intraocular pressure (IOP) dynamic change from episode to intermittent period in patients with Posner-Schlossman syndrome (PSS). PATIENTS AND METHODS: Seventeen cases of typical PSS were collected in this study. Both their random IOP in episodes/intermittent period and 24-h IOP in intermittent period were measured. The mean IOP as well as the peak and the valley value of 24-h IOP were calculated. Those data were statistically analyzed. RESULTS: The IOP in affected eye in episodes is higher than that of the contralateral eye statistically; while in intermittent period the mean IOP (p = 0.001), the peak (p = 0.029) and the valley (p = 0.004) value of 24-h IOP in affected eye are statistically different with that of the contralateral eye. All of these parameters of the affected eye in intermittent period are lower than that of the contralateral eye obviously. CONCLUSION: The dynamic observations of IOP in episodes and intermittent period confirmed the IOP crossover phenomenon inpatients with typical PSS and this observation may be important in the differential diagnosis of PSS.

[Determination of cytomegalovirus IgG synthesis by the albumin correction in the aqueous humor of posner-schlossmann syndrome].

Objective: To evaluate the usefulness of albumin correction in determination of cytomegalovirus IgG in the aqueous humor of Posner-Schlossman syndrome (PSS) patients. Methods: Cases series studies. Forty-two patients (26 men and 16 women) who were diagnosed as PSS were enrolled from Oct. 2009 to Oct. 2015 at the Eye and ENT Hospital. During the same period, 20 patients with primary open-angle glaucoma (POAG) and 30 patients with bacterial endophthalmitis or retinal necrosis were enrolled as negative control group and inflammatory disease control group, respectively. Aqueous humor and serum samples were assayed to detect CMV IgG by enzyme-linked immunosorbent assay (ELISA), and albumin by scattering immunonephelometry. CMV DNA in aqueous humor was assayed by polymerase chain reaction (PCR). The ratio which was calculated as the (aqueous humor CMV IgG/serum CMV IgG)/(aqueous humor concentration of albumin/serum albumin concentration) over 0.6 was considered as intraocular antibody formation. Performance of differentiating control eyes from eyes with CMV-positive PSS was evaluated by the receiver operating characteristic curve. The ANOVA test, Mann-Whitney test and Chi-square test were performed to compare the differences among groups. Results: The detectable rate of CMV IgG antibody in the aqueous humor was 76.2%, 100.0% and 10.0% in PSS, inflammatory disease control and POAG groups, respectively. The levels of CMV IgG antibody in the PSS groups were significantly higher than that of POAG groups (Z=4.23, P<0.001).The positive rate corrected by the albumin was 71.4%, 3.3% and 0.0%.The corrected positive rate in PSS groups was significantly higher than that of the inflammatory disease control and POAG groups (χ(2)=30.38, P<0.01; χ(2)= 24.89, P<0.01), with a sensitivity of 75.0% and a specificity of 98.0%. The area under the curve for calibrated ratio was 0.942 (95%CI: 0.859 to 0.984) which was higher than that of CMV IgG (Z=6.19, P<0.001).The corrected positive rate of CMV IgG antibody (71.4%) was higher than that of CMV DNA (47.6%, χ(2)=4.003, P=0.045). Conclusions: CMV IgG antibody ratio which was corrected by aqueous humor and serum albumin could effectively improve aqueous antibody specificity in PSS patients. Furthermore, CMV IgG antibody ratio combined with PCR could improve the sensitivity of CMV detection. All of which help clarify the CMV infection in PSS in CMV DNA negative eyes.

Full-thickness choroidal thinning as a feature of Fuchs Uveitis Syndrome: quantitative evaluation of the choroid by Enhanced Depth Imaging Optical Coherence Tomography in a cohort of consecutive patients.

PURPOSE: To perform a quantitative analysis of choroidal thickness in patients with Fuchs Uveitis Syndrome (FUS) using enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS: All patients underwent comprehensive ophthalmic examination, including best-corrected visual acuity, slit-lamp biomicroscopy, applanation tonometry, axial length measurements with a swept-source biometer (IOLMaster 700, Carl Zeiss Medic AG, Jena, Germany) and macular 30° linear EDI- B-scan SD-OCT section (Spectralis HRAII+OCT, Heidelberg Engineering, Heidelberg, Germany) in both eyes. Analysis of choroidal thickness was performed at three different locations: subfoveally, 750 µm nasally, and 750 µm temporally to the fovea. Patients having received any surgery or intravitreal injections in the last 12 months and with axial length variance ≥ 1 mm between both eyes were excluded. RESULTS: Sixteen eyes of eight consecutive patients with unilateral FUS were included. Segmented analysis of the choroid, separately considering Haller's layer and Sattler's-choriocapillaris layers, showed statistically significant lower values (p < 0.05) in affected eyes (FEs) compared to fellow eyes (NFEs). In NFEs, total choroidal thickness mean values ranged from 305.62 ± 92.96 µm to 347.50 ± 91.55 µm; in FEs those values were significantly lower (p < 0.05), ranging from 232.62 ± 89.33 µm to 255.62 ± 89.33 µm. CONCLUSION: Diffuse and full-thickness choroidal thinning in FEs was observed. Considering the absence of significant axial length differences between FEs and NFEs in our patient series, these data seem to suggest that the full-thickness choroidal thinning in FEs may be due to the inflammatory process. In that way, FUS might be regarded as an inflammatory condition involving the whole uveal tunic, even the posterior part of it, definitively supplanting the early definition of "heterochromic iridociclytis".

Comparison between Outcomes of Vitrectomy in Granulomatous and Nongranulomatous Uveitis.

PURPOSE: The aim of this study was to compare the outcomes of vitrectomy in granulomatous uveitis and nongranulomatous uveitis insufficiently managed by immunosuppressive therapy. METHODS: Thirty-eight eyes with granulomatous uveitis and 17 eyes with nongranulomatous uveitis that underwent vitrectomy for ocular complications between July 2006 and August 2012 were reviewed retrospectively. Visual acuity and ocular inflammation scores before and 6 months after surgery were compared. Patients treated with vitrectomy alone and those in whom vitrectomy was combined with phacoemulsification were analyzed separately. RESULTS: The mean visual acuity improved significantly both in granulomatous and nongranulomatous uveitis. In granulomatous uveitis, the mean inflammation scores decreased significantly both in the anterior segment and in the posterior segment. In nongranulomatous uveitis, the mean inflammation score in the posterior segment decreased significantly, although it did not change in the anterior segment. CONCLUSION: Vitrectomy was effective for treating ocular complications both in granulomatous uveitis and nongranulomatous uveitis, with favorable outcomes of improved visual acuity and decreased uveitis activity.

[Characteristics of inflammatory response in patients after senile cataract surgery].

The aim of the work was to study prognostic value of some laboratory markers (anti-DNA antibodies, cell adhesive molecules, neopterin) in heriatric patients with exudative inflammation after cataract surgery. 12 in-patients with postoperative iridocyclitis and endophthalmitis were included. The assays were taken twice: after admission and before discharging. The follow-up period was 6 months. Preliminary data show that high serum levels of sVCAM, sICAM and anti-DNA antibodies, as well as very low levels of anti-DNA antibodies seems to be associated with poor outcomes in those patients (enucleation, blindness, lens extraction). Small cohort doesn't allow us to make strict conclusion about prognostic value of these laboratory markers. The study should be continued.
