ABSTRACT

In recent years, the combined surgery of phacoemulsification, intraocular lens implantation, and goniosychialysis has gradually emerged as a primary and effective approach in treating primary angle-closure glaucoma with cataracts. However, with the continuous progress of medical technology, postoperative intraocular pressure control is no longer the sole pursuit. Patients increasingly aspire to achieve higher postoperative visual quality. In order to ensure that patients attain a better refractive status and higher visual quality postoperatively, it is essential to minimize the negative impact caused by primary angle-closure glaucoma. This involves personalized selection of different intraocular lenses or calculation formulas,etc. Evaluation metrics for visual quality encompass visual acuity, contrast sensitivity, higher-order aberrations, subjective perception, etc. Therefore, this paper provides a comprehensive review of postoperative refractive shift, higher-order aberrations, contrast sensitivity and their influencing factors, and the selection of intraocular lenses for patients undergoing combined surgery for primary angle-closure glaucoma with cataracts.

ABSTRACT

Primary angle-closure glaucoma(PACG)is a common cause of blindness, and angle closure is a fundamental pathologic process in PACG. With the development of ophthalmic equipment, the pathogenesis of PACG has been better understood. In addition to the traditional mechanisms of pupillary block and plateau iris, it has been found that its pathogenesis is not only related to abnormal ocular anatomy, but also more closely related to ocular dynamics, genetic factors, and psychophysiologic stressors. This article summarizes the pathogenesis and risk factors of PACG in conjunction with literature reports, with a view to providing guidance for clinical work and useful theoretical support for early diagnosis and treatment options for glaucoma.

ABSTRACT

AIM: To investigate the characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma(PACG).METHODS: A total of 48 first-degree relatives of PACG patients aged 40-60 who were treated in the Affiliated Eye Hospital of Nanchang University from September 2020 to October 2022 were selected as the observation group. Additionally, 40 cases(40 eyes)of healthy individuals without glaucoma and family history of glaucoma at the same age group were collected as the control group. They were divided into younger group(40-49 years old)and elder group(50-60 years old). All subjects were examined with ultrasound biomicroscopy(UBM)and were measured using camera measure software. The parameters mainly included anterior chamber depth(ACD), anterior chamber area(ACA), anterior chamber width(ACW), anterior segment depth(ASD), angle open distance(AOD500), trabecular iris angle(TIA), trabecular iris area(TISA500), lens vault(LV), iris curve(IC), iris thickness(IT500), scleral ciliary process angle(SCPA), and iris ciliary process distance(ICPD).RESULTS: ACD, ACA, AOD500, TISA500 and TIA in the observation group were lower than those of the control group, and LV and IC were higher than those of the control group(all P<0.05). ACD, ACA, AOD500, TISA500, and TIA of the elder group were lower than those in the age-matched control group, while LV and IC were larger than those of the age-matched control group(all P<0.05). ACD, AOD500, TISA500, and TIA of the younger observation group were smaller than those of the age-matched control group, but LV and IC were significantly larger than those of the age-matched control group(all P<0.05). ACD, ACA, AOD500, TISA500 and TIA of the elder observation group were significantly lower than those of the younger observation group, and LV and IC were significantly larger than those of the younger observation group(all P<0.05). There was a difference in the distribution of ACD between the observation group and the control group(P<0.05), and the proportion of moderate to severe shallow anterior chambers was 10 times that of the control group. Correlation analysis showed that TISA500 was positively correlated with ACD and ACA, and negatively correlated with LV and IC, and TISA500 was mainly influenced by LV. IC had a positive correlation with LV and a negative correlation with ACD and ACA.CONCLUSION: First-degree relatives of PACG with normal axial length have a high risk of angle closure. The anterior segment structures of first-degree relatives of PACG are more crowded than normal individuals, and the lens forward shift may be the initial influencing factor for narrow angle.

ABSTRACT

Purpose: To evaluate the refractive status and ocular biometric parameters in primary angle?closure glaucoma (PACG) eyes with different axial lengths (ALs). Methods: In total, 742 Chinese PACG subjects with complete ophthalmic examinations were enrolled. The refractive status was categorized as myopia (spherical equivalent [SE] ??0.5 D), emmetropia (?0.5 D < SE < +0.5 D), and hyperopia (SE ?+0.5 D), whereas the AL was divided into short (AL <22.5 mm), regular (22.5 ? AL <23.5 mm), and long (AL ?23.5 mm). The refractive status and ocular biometric parameters were compared among different AL groups. Results: The mean AL of the PACG eyes was 22.53 ± 0.84 mm (range: 19.68–25.57 mm). The refractive status was significantly different among different AL groups (P < 0.001). Also, 92.6% of hyperopic PACG eyes showed AL <23.5 mm, and 19.0% of myopic PACG eyes showed AL ?23.5 mm. The SE showed significant differences among different AL groups only in the hyperopic subjects (P = 0.012). The AL was significantly longer in myopic eyes (P < 0.001). The PACG eyes with longer AL exhibited lower keratometry, longer central anterior chamber depth and corneal diameter, and lens position and relative lens position closer to the anterior (P < 0.001). Conclusion: Axial hyperopia was common in PACG eyes, and axial myopia was not uncommon. Relatively anterior lens position could explain the occurrence of PACG in the eyes with long AL.

ABSTRACT

AIM: To investigate the relationship between the levels of chemokine receptor 2(CXCR2)and basic fibroblast growth factor(bFGF)in aqueous humor and the prognosis of trabeculectomy in patients with acute primary angle-closure glaucoma(APACG).METHODS: A total of 80 cases(80 eyes)APACG patients who underwent trabeculectomy in our hospital from June 2020 to January 2022 were collected in the case group. According to the postoperative efficacy, they were grouped into a success group of 60 cases(60 eyes)and a failure group of 20 cases(20 eyes). Another 86 cataract patients(86 eyes)who underwent phacoemulsification with normal intraocular pressure in our hospital during the same period were included in the control group. Enzyme linked immunosorbent assay was applied to detect the levels of CXCR2 and bFGF in aqueous humor. ROC curve was applied to analyze the value of predicting trabeculectomy failure in APACG patients by the levels of CXCR2 and bFGF in aqueous humor. Furthermore, multivariate Logistic regression was applied to analyze the influencing factors of trabeculectomy failure in APACG patients.RESULTS: The levels of CXCR2 and bFGF in the aqueous humor of the case group were significantly higher than those of the control group(P&#x003C;0.05). The levels of CXCR2 and bFGF in the aqueous humor of the failed group and the proportion of patients with postoperative shallow anterior chamber were significantly higher than those of the successful group(P&#x003C;0.05). The AUC for predicting trabeculectomy failure in APACG patients using CXCR2 and bFGF levels alone and in combination was 0.885, 0.883 and 0.953, respectively. CXCR2 and bFGF were independent risk factors for trabeculectomy failure in APACG patients(P&#x003C;0.05).CONCLUSION: The levels of CXCR2 and bFGF in the aqueous humor of APACG patients are obviously elevated, and both are risk factors for trabeculectomy failure.

ABSTRACT

AIM: To evaluate the damage to optic nerve by detecting the morphological and functional changes of optic nerve in patients with acute primary angle-closure glaucoma.METHODS: The correlation among the positive rates of fundus photography, visual field examination, optical coherence tomography(OCT)scan of the optic nerve, and pattern visual evoked potentials(P-VEP)were analyzed in 28 patients with acute primary angle-closure glaucoma affecting.RESULTS: Among 28 eyes of 28 patients, optic nerve images were obtained in 25 eyes(89%), optic disc color in 25 eyes: there were 9 normal eyes and 16 eyes with congestion and edema, without pallor; C/D: &#x003C; 0.6 in 5 eyes, &#x003E; 0.6 in 1 eye, and indistinguishable in 19 eyes; disk edge: 6 eyes were normal, and 19 eyes could not be distinguished.Optic nerve images could not be obtained in 3 eyes(11%). Visual field examination: 9 eyes(32%)were normal, 2 eyes(7%)had visual field damage, 8 eyes(29%)had no reference value due to cataract visual field examination, 2 eyes(7%)had false positive rate ≥15%, and 7 eyes(25%)could not cooperate with the examination. The retinal nerve fiber layer thickness around optic disc was measured by OCT in 26 eyes(93%), of which the thickness of nerve fiber layer was normal in 24 eyes and local thinning in 2 eyes. Severe opacification of refractive stroma could not be measured in 2 eyes(7%). PVEP showed that the peak of P100 was normal in 18 eyes(64%)and prolonged in 10 eyes(36%). The amplitude of P100 wave was normal in 11 eyes(39%)and decreased in 17 eyes(61%).CONCLUSION: After a major acute attack of primary angle-closure glaucoma, the optic nerve does not exhibit typical glaucomatous damage but may present with optic disc congestion and edema. Therefore, a comprehensive evaluation combining subjective and objective examination methods is necessary for optic nerve assessment, and currently, no more precise assessment method is available.

ABSTRACT

AIM: To explore the clinical application value of analysis system for ultrasound biomicroscopy(UBM)images of anterior chamber angle(ACA)based on deep learning algorithm.METHODS: A total of 4 196 UBM images were obtained from 675 patients(1 130 eyes)at the Eye Center of Renmin Hospital of Wuhan University from January 2021 to June 2022 were collected to build an image dataset. Using Unet++network to automatically segment ACA tissue, a support vector machine(SVM)algorithm was developed to automatically classify opening and closing of chamber angle, and an algorithm to automatically locate the sclera spur and measure ACA parameters was developed. Furthermore, a total of 631 UBM images of 127 subjects(221 eyes)at Huangshi Aier Eye Hospital and 594 UBM images of 188 subjects(257 eyes)at Zhongnan Hospital of Wuhan University were selected to evaluate the performance of the system under different environments.RESULTS: The accuracy of the analysis system constructed in this study for chamber angle opening and closing was 95.71%. The intra-class correlation coefficient(ICC)values of all ACA angle parameters were greater than 0.960. ICC values of all ACA thickness parameters were greater than 0.884. The accurate measurement of ACA parameters depended in part on the accurate location of the scleral spur.CONCLUSION: The intelligent analysis system constructed in this study can accurately and effectively evaluate ACA images automatically and is a potential screening tool for the rapid identification of ACA structures.

ABSTRACT

Minimally invasive glaucoma surgery (MIGS) has been successfully incorporated in clinical practice in recent years.Increasing evidence shows that it also plays an important role in the treatment of primary angle-closure glaucoma (PACG). Goniosynechialysis (GSL) is a key surgical procedure used by MIGS for PACG, which involves separating the peripheral anterior synechia and reopening the angle.However, there is still a lack of uniform standards for indications and surgical procedures.Therefore, it is necessary to formulate a detailed and complete expert consensus on surgical procedures to standardize the application of clinicians in the treatment.

ABSTRACT

Minimally invasive glaucoma surgery (MIGS) has been successfully incorporated in clinical practice in recent years.Increasing evidence shows that MIGS also plays an increasingly important role in the treatment of primary angle-closure glaucoma (PACG). Surgical peripheral iridectomy (SPI) plus goniosynechialysis (GSL) and goniotomy (GT), as a new procedure, has been proven to be safe and effective in the treatment of PACG with no or mild cataracts.However, there is still a lack of uniform standards for indications, surgical procedures, and perioperative medication.Therefore, it is necessary to formulate a detailed and complete expert recommendations on surgical procedures to standardize the application of combined SPI+ GSL+ GT in the treatment.Some experts in glaucoma treatment and management in China have discussed the current problems and developing trend in MIGS for PACG and put forward the expert recommendations of standard process, including indications, anaesthetic methods, surgical site, operating procedure and rational administration of drugs in perioperation, in order to standardize the medical process of clinicians using combined SPI+ GSL+ GT in PACG treatment and lay a foundation for better evaluation of the efficacy of MIGS.

ABSTRACT

Objective:To evaluate the efficacy and safety of phacoemulsification combined with gonioscopy-assisted angle plasty (Phaco-GAAP) for primary angle closure glaucoma (PACG) with cataract.Methods:A case series study was carried out.Twenty-five eyes of 22 patients with PACG and cataract were enrolled in Beijing Tongren Hospital from April 2022 to August 2022.All of the patients received Phaco-GAAP surgery.During the operation, viscoelastic-assisted goniosynechialysis was performed at first, followed by a secondary angle plasty for residual peripheral anterior synechiae (PAS) based on the quantified assessment by gonioscopy, and the extent of PAS was recorded intraoperatively.The operated eyes were followed at 1 day, 1 week, 1 month and 3 months after surgery to evaluate intraocular pressure (IOP), PAS range, the number of anti-glaucoma drugs application, operation-related complications, and success rate.The qualified success rate was defined as medicine-controlled IOP ≤21 mmHg after surgery, and complete success rate was defined as IOP ≤21 mmHg without any anti-glaucoma medication.This study complied with the Declaration of Helsinki and was approved by the Ethics Committee of Beijing Tongren Hospital (TRECKY2021-136). Written informed consent was obtained from each patient prior to entering the research cohort.Results:The extent of PAS was [270(225, 360)°], [165(110, 215)°] and [100(35, 175)°] at preoperation, first and secondary angle plasty, respectively, showing a significant difference among them ( χ2 =40.742, P<0.001). The PAS range was significantly reduced at first angle plasty in comparison with preoperation and was significantly reduced at secondary angle plasty in comparison with at first angle plasty (both at P<0.001), and the proportion of the angle PAS range ≥180° decreased from 48% to 24% after second angle plasty.In 13 eyes finished gonioscopy, the PAS range was [240(195, 305)°], [60(25, 182.5)°], [170(120, 275)°]and [180(140, 280)°]at preoperation, at the end of operation, postoperative 1 month and 3 months, respectively, with a significant difference ( χ2 =23.631, P<0.001). The PAS range was significantly smaller at postoperative 1 month, 3 months than that at preoperation (both at P=0.004) and larger than that at the end of operation ( P=0.011, P=0.003). The IOP was (40.19±17.23), (15.80±7.98), (13.89±5.09), (12.80±3.79) and(13.24±2.78) mmHg before operation and 1 day, 1 week, 1 month and 3 months after operation, respectively, showing a significant difference ( F=44.031, P<0.001), and the IOP was significantly reduced after operation (all at P<0.001). The PAS range at the end of operation was positively correlated with preoperation ( rs=0.409, P=0.042). The complete and qualified success rates were 95.8%, 95.8% for postoperative 1 month, 95.8% and 100% for postoperative 3 months, respectively.The primary complication was intraoperative anterior chamber angle hemorrhage, with an incidence of 68%. Conclusions:Phaco-GAAP can intraoperatively quantify PAS range and guide secondary angle plasty, therefore, it is an effective and safe surgical intervention for PACG with cataract.

ABSTRACT

Primary angle closure glaucoma(PACG)is the leading type of glaucoma in Asia, especially in China. PACG still has a high proportion of angle closure after laser peripheral iridectomy(LPI). Plateau iris is one of the non-pupillary blockage factors that cause angle closure. With the wide application of ultrasound biomicroscopy(UBM)in ophthalmology, the understanding of plateau iris has been deepened continually. This paper will elaborate the concept, mechanism, prevalence, relationship with angle closure, diagnostic criteria and the treatment of plateau iris, aiming to have a deeper understanding of the relationship between plateau iris and PACG, and to provide references for the treatment and research of PACG in the future.

ABSTRACT

AIM: To investigate the changes in peripapillary choroidal thickness(pCT)within 1a of the first episode of acute primary angle closure glaucoma(APACG).METHODS: A prospective cohort study. A total of 31 patients with APACG who admitted to the ophthalmology department of Shijiazhuang People's Hospital from October 2015 to September 2019 were selected, with 31 eyes in attack group, 31 fellow eyes in preclinical group and 30 cases(30 eyes)in control group. pCT of the three groups was measured respectively at the attack period, 1wk, 1, 3, 6mo and 1a after surgery.RESULTS: The pCT of the attack group was thicker than that in the attack period when at 1wk after surgery, and continued to become thinner within the following 1a(P&#x0026;#x003C;0.05). The pCT of the attack group was thicker than that of the other two groups during the attack period and at 1wk after surgery, while it became thinner at 1a(P&#x0026;#x003C;0.05). In the attack group, the average pCT was positively correlated with the duration of intraocular hypertension and negatively correlated with the anterior chamber depth(P&#x0026;#x003C;0.05).CONCLUSION: For patients with first episode of APACG, pCT was diffusely thickened during attack and at 1wk after surgery. The pCT returned to normal at 1mo, while it became thinner at 1a. Furthermore, the average pCT was positively correlated with the duration of intraocular hypertension, and the choroidal thickness may play an important role in the attack of APACG.

ABSTRACT

Purpose: To evaluate and correlate corneal endothelium parameters with the severity of primary glaucoma. Methods: This prospective case?control study was conducted on 150 eyes of 80 newly diagnosed primary open?angle glaucoma (POAG), chronic primary angle?closure glaucoma (cPACG), and normal?tension glaucoma (NTG) patients in a tertiary care center. Endothelial parameters including endothelial cell count (ECC), percentage of hexagonal cells, and coefficient of variation of cell size were analyzed. Glaucoma cases were further sub?grouped into early, moderate, and severe glaucoma and compared for endothelial parameters. Chi?square, Fischer’s exact test, independent sample t?test, and analysis of variance were performed using IBM® SPSS® Statistics version 28. Results: The ECC was markedly reduced in cases (2281 cells/mm2) versus controls (2611 cells/mm2) (P < 0.001). The POAG (2251 cells/mm2) and cPACG (2287 cells/mm2) eyes had significantly a lower ECC compared to healthy controls (P < 0.001), whereas NTG eyes had a lower mean ECC (2538 cells/mm2), but it was not statistically significant (P > 0.05) when compared with controls. The ECC decreased with an increase in severity as patients with early glaucoma had an ECC of 2284 cells/mm2, moderate 2261 cells/mm2, and severe 2086 cells/mm2, and the difference was statistically significant. Conclusion: A significant decrease in corneal ECC was observed in POAG and cPACG patients when compared with healthy controls of the same age group. Mechanical damage following an elevated intra?ocular pressure for a longer duration may be attributed to morphological and consequent functional damage to endothelial cells.

ABSTRACT

Purpose: To correlate and analyze the pattern of the visual field (VF) defects by perimetry and anterior chamber angle parameters by AS-OCT in primary angle-closure glaucoma (PACG) across varied severity levels on presentation to a tertiary eye care center. Methods: This was a cross-sectional study, which included 323 eyes of clinically diagnosed cases of PACG. Glaucoma severity was categorized according to mean deviation (MD) as mild (-6.00 dB or more), moderate (-6.01 to -12.00 dB), and severe (-12.01 to -30.00 dB). AS-OCT measured the nasal (N) and temporal (T) angle opening distance at 500 ?m (AOD 500) and 750 ?m (AOD 750), anterior chamber angle (ACA), lens vault (LV), and anterior chamber width (ACW). The VF severity was then correlated with the AS-OCT parameters using statistical analysis. Results: The mean age ± standard deviation (SD) of the patients included in the study was 56.03 ± 8.6 years, with a 1:1.2 gender ratio. The number of eyes with mild, moderate, and severe VFs were 140 (43.3%), 88 (27.24%), and 95 (29.41%), respectively. There was no statistically significant correlation in the mean anterior chamber angle parameters (AOD 500, AOD 750, ACA 500, ACA 750, LV, ACW, and axial length (AL)) among the groups. However, the correlation between AOD 500 and LV thickness was found to be significant (P = 0.0000) with a negative Spearman’s rank correlation coefficient (r = -0.3329). Conclusion: The ACA parameters obtained by AS-OCT along the horizontal axis after elimination of pupillary block by laser peripheral iridotomy do not correlate and cannot be used to assess the disease severity of PACG

ABSTRACT

Primary angle-closure glaucoma (PACG) is a common subtype of glaucoma and one of the leading causes of blindness in Asia.Trabeculectomy has been recognized as an effective filtering surgery for PACG and is widely used in clinical practice, but its high risk of postoperative complications, especially bleb scarring over time can not be ignored.Nowadays, non-bleb-based minimally invasive glaucoma surgeries (MIGS) have attracted much attention.Surgeries opening, restoring, or expanding Schlemm canal to reconstruct aqueous humor outflow pathway is one of the MIGS and able to achieve moderate intraocular pressure (IOP) reduction, which has been widely used in the treatment of primary open-angle glaucoma (POAG) for a long time.However, based on the pathogenesis of PACG and its similar pathological changes in Schlemm canal to POAG, some retrospective studies and prospective single-arm studies discovered that Schlemm canal surgery combined with phacoemulsification and/or goniosynechialysis appears to lower IOP well and safe in PACG eyes in recent years.Whether Schlemm canal surgery is also suitable or effective for PACG is getting some attention and is still controversial up to now, mostly due to some differences in pathogenesis between PACG and POAG, it is necessary to perform randomized controlled trials to confirm the efficacy of Schlemm canal surgery for PACG and upgrade the therapeutic strategy of PACG.

ABSTRACT

@#Primary angle-closure glaucoma(PACG)is the most common type of glaucoma in clinical. It is characterized by progressive and irreversible development with high global incidence and high possibility of blindness. The pathogenesis of PACG is complicated. It is not only associated with the abnormality of the ocular anatomy, such as the small cornea, short eye axis and shallow anterior chamber, but also found that the abnormality of the lens, iris, ciliary body and choroid are related to the pathogenesis of PACG in recent years. Moreover, the occurrence of PACG is also closely related to genetic and psychological stress factors. Our study summarized some literatures and made a brief discussion on the pathogenesis of PACG from the three aspects of anatomical characteristics, genetic factors, and psychological stress. We hope to provide useful theoretical support for the early diagnosis and treatment of glaucoma.

ABSTRACT

@#Primary angle-closure glaucoma(PACG)is an irreversible disease-causing blindness, the damage of optic nerve is caused by elevated intraocular pressure(IOP)as a result of angle-closure. Angle-closure is a fundamental pathologic process in PACG. In addition, PACG is characterized by elevated IOP as a result of mechanical obstruction of the trabecular meshwork by either apposition of the peripheral iris to the trabecular meshwork or by a synechial closed angle. In recent years, with the development of ophthalmic imaging technology, the iris has been recognized as necessary to complement anatomical risk factors in assessing the risk of PACG. In this review, we intend to describe the potential role of the iris in the pathogenesis of PACG, so as to provide new ideas and directions for prevention and treatment of such disease.

ABSTRACT

@#AIM: To evaluate and compare the quality of life of patients submitted to phacoemulsification combined with goniosynechialysis(PPI+GSL)and trabeculectomy, and analyze the potentially involved variables.<p>METHODS: A perspective, randomized case-control study was conducted. Patients with acute primary angle-closure glaucoma(ACG)and early cataracts underwent PPI+GSL implantation(group A, <i>n</i>=29)and trabeculectomy(group B, <i>n</i>=30). The quality of life was assessed using the National Eye Institute 25-Item Visual Function Questionnaire(NEI-VFQ-25)before and 6mo after surgery. Intraocular pressure(IOP), best corrected visual acuity(BCVA), review frequency and the basic characteristics were recorded simultaneously.<p>RESULTS: Compared with preoperative status, the IOP in both groups was significantly decreased(all <i>P</i><005), and the BCVA was significantly increased in group A(<i>P</i><0.05), while did not differ significantly in group B(<i>P</i>>0.05). Besides, group B presented higher review frequency than group A(<i>P</i><0.05). Moreover, significant increases in postoperative scores were founded in the two groups respectively(all <i>P</i><0.05). Compared with group B, group A had better postoperative performance in items of general vision, ocular pain, long-distance activities, social functioning and role limitations(all <i>P</i><0.05). Besides, group A presented significantly higher net increases in postoperative total scores than group B(<i>P</i><0.05), which was positively associated with the degree of the BCVA recovery and negatively associated with review frequency(<i>R</i><sup>2</sup>=0.48, <i>F</i>=5.00, <i>P</i><0.05).<p>CONCLUSION: APACG patients with early cataracts, PPI+GSL determines better improvement in quality of life compared to trabeculectomy.

ABSTRACT

@#AIM: To investigate the changes and related factors of choroidal thickness(CT)in acute primary angle-closure glaucoma(APACG), and chronic primary angle-closure glaucoma(CPACG).<p>METHODS: It was a retrospective study. A total of 35 patients(43 eyes)with APACG, 26 patients(46 eyes)with CPACG and 46 patients(81 eyes)with normal eye condition and used as the control group in the study. EDI-OCT was used to measure and compare the foveal, nasal, temporal, superior and inferior CT of APACG, CPACG and normal control groups. The CT were labeled as subfoveal choroidal thickness(SFCT), nasal 2mm(N 2mm), temporal 2mm(T 2mm), superior 2mm(S 2mm), inferior 2mm(I 2mm).Linear regression analysis was used to explore the related factors of CT. Logistic regression analysis was used to evaluate the association between CT and presence of APACG and CPACG.<p>RESULTS: There was no significant difference in CT of APACG, CPACG and normal control group(<i>P</i>>0.05). CT of all sites was negatively correlated with axial length(AL). N 2 mm and I 2 mm were also negatively correlated with age, anterior chamber depth(ACD), SFCT was negatively correlated with age and AL(<i>P</i><0.05). Multivariate Logistic analysis showed that there was an association between S 2mm and APACG(<i>P</i>=0.029), the odds ratio(<i>OR</i>)and 95% confidence interval(<i>CI</i>)was 0.975(0.953, 0.997). There was no association between CPACG and CT at all locations(<i>P</i>>0.05).<p>CONCLUSION: Age, AL and ACD are the factors that related to choroidal thickness. It is also confirm that there is an association between decreased S 2mm and APACG. However, there is no correlation between CPACG and CT at all locations.
