This study investigated the influence of asymmetric corneal hysteresis (CH) on asymmetric visual field impairment between right and left eyes in patients with primary open-angle glaucoma (POAG) without a history of intraocular surgery. CH, corneal resistance factor (CRF), and corneal compensated intraocular pressure (IOPcc) were measured using the Ocular Response Analyzer. Differences between the eyes (right eye–left eye: DIFRL) and CH-based and in target parameters (higher CH eye–lower CH eye: DIFCH) were calculated in the same patient. In 242 phakic eyes of 121 patients, older age (p < 0.001), lower CH (p = 0.001), and lower CRF (p = 0.007) were significantly associated with worse standard automated perimetry (SAP) 24-2 mean deviation (MD). The DIFsRL in axial length (p = 0.003), IOPcc (p = 0.028), and CH (p = 0.001) were significantly associated with the DIFRL in SAP24-2 MD, but not in central corneal thickness (CCT), Goldmann applanation tonometry (GAT) measurement, and CRF. When dividing the patients into two groups based on the median of the CH DIFsCH (0.46), the DIFsCH in CRF (p < 0.001), IOPcc (p < 0.001), CCT (p = 0.004), SAP24-2 MD (p < 0.001), and SAP10-2 MD (p = 0.010) were significantly different between the groups. Large inter-eye asymmetry in CH is an important explanatory factor for disease worsening in patients with POAG.

PURPOSE: Patients with an eye disease often report nyctalopia, hemianopia, and/or photophobia. We hypothesized that such symptoms are related to the disease impacting the dynamic range of lightness perception (DRL). However, there is currently no standardized approach for measuring DRL for clinical use. We developed an efficient measurement method to estimate DRL. STUDY DESIGN: Clinical trial METHODS: Fifty-five photophobic patients with eye disease and 46 controls participated. Each participant judged the appearance of visual stimuli, a thick bar with luminance that gradually changed from maximum to minimum was displayed on uniform background. On different trials the background luminance changed pseudo-randomly between three levels. The participants repeatedly tapped a border on the bar that divided the appearance of grayish white/black and perfect white/black. We defined the DRL as the ratio between the luminance values at the tapped point of the border between gray and white/black. RESULTS: The mean DRL of the patients was approximately 15 dB, significantly smaller than that of the controls (20 dB). The center of each patient's DRL shift depending on background luminance, which we named index of contextual susceptibility (iCS), was significantly larger than controls. The DRL of retinitis pigmentosa was smaller than controls for every luminance condition. Only the iCS of glaucoma was significantly larger than controls. CONCLUSIONS: This measurement technique detects an abnormality of the DRL. The results support our hypothesis that the DRL abnormality characterizes lightness-relevant symptoms that may elucidate the causes of nyctalopia, hemeralopia, and photophobia.

PRECIS: The foveal avascular zone (FAZ) in optical coherence tomography angiography is significantly correlated with retinal inner layer thickness, Humphrey field analyzer (HFA) 10-2 sensitivity threshold, and mean deviation (MD) value in open-angle glaucoma patients. PURPOSE: The purpose of this study was to measure the FAZ area using optical coherence tomography angiography and investigate its relationship with retinal inner layer thickness and visual field defects in eyes with open-angle glaucoma. PARTICIPANTS AND METHODS: A total of 52 eyes with open-angle glaucoma from 52 patients. FAZ area was measured using optical coherence tomography angiography in angio-macula mode. Thicknesses of retinal nerve fiber layer (RNFL), ganglion cell layer plus inner plexiform layer (GCL+IPL), and ganglion cell complex (GCC) were determined using a 7 mm×7 mm macular (V) map via 3D-OCT. Correlations of FAZ area with sensitivity threshold measurements, foveal threshold (FT), and MD value in the HFA10-2 visual field were analyzed for each inner retinal layer. RESULTS: FAZ area was 0.26±0.07 mm; overall mean thicknesses were 19.14±6.55 μm (RNFL), 57.34±5.93 µm (GCL+IPL), and 75.87±10.96 μm (GCC); mean FT was 35.23±3.15 dB, and sensitivity threshold was 20.81±7.22 dB in the HFA10-2 visual field. FAZ area was significantly correlated with the thickness of individual retinal layers in the entire field (RNFL, P<0.001; GCL+IPL, P<0.001; GCC, P<0.001), sensitivity threshold (P=0.01), FT (P<0.001), and MD value (P=0.011). CONCLUSION: FAZ area was significantly negatively correlated with retinal inner layer thickness, sensitivity threshold, FT, and MD value in the HFA10-2 visual field.

BACKGROUND: Steep Trendelenburg position (ST) during robot-assisted radical prostatectomy (RARP) poses a risk of increase in intraocular pressure (IOP) in men receiving robot-assisted radical prostatectomy (RARP). The aim of the study was to identify clinicopathological factors associated with increased IOP during RARP. METHODS: We prospectively studied 59 consecutive prostate cancer patients without glaucoma. IOP was measured at 6 predefined time points before, during and after the operation (T1 to T6). RESULTS: Compared with T1, IOP decreased after beginning of anesthesia(T2) (by - 6.5 mmHg, p < 0.05), and increased 1 h after induction of pneumoperitoneum in the steep Trendelenburg position (ST) (T3) (+ 7.3 mmHg, p < 0.05). IOP continued to increase until the end of ST (T4) (+ 10.2 mmHg, p < 0.05), and declined when the patient was returned to supine position under general anesthesia (T5) (T1: 20.0 and T5: 20.1 mmHg, p above 0.05). The console time affected the elevation of IOP in ST; IOP elevation during ST was more prominent in men with a console time of ≥4 h (n = 39) than in those with a console time of < 4 h (n = 19) (19.8 ± 6.3 and 15.4 ± 5.8 mmHg, respectively, p < 0.05). Of the 59 patients, 29 had a high baseline IOP (20.0 mmHg or higher), and their IOP elevated during ST was also reduced at T5 (T1: 22.6 and T5: 21.7 mmHg, p above 0.05). There were no postoperative ocular complications. CONCLUSIONS: Console time of < 4 h is important to prevent extreme elevation of IOP during RARP. Without long console time, RARP may be safely performed in those with relatively high baseline IOP.

Purpose: To clarify the clinical features of patients with exfoliation glaucoma (XFG) requiring surgical intervention. Study Design. Retrospective study. Methods: The study included 46 eyes from 36 XFG patients, 85 eyes from 53 primary open-angle glaucoma (POAG) patients, and 54 eyes from 35 normal-tension glaucoma (NTG) patients. Age, duration of previous glaucoma treatment, intraocular pressure, medication scores, visual function, and surgical procedure were compared among the three patient groups. Results: The XFG group had the highest mean age (XFG: 75.7 ± 8.3 years, POAG: 65.8 ± 12.8 years, and NTG: 53.3 ± 12.8 years; p < 0.001) and the shortest mean duration of previous treatment with glaucoma medication (XFG: 5.1 ± 3.5 years, POAG: 8.9 ± 6.9 years, and NTG: 8.9 ± 5.9 years; p < 0.001). Intraocular pressure and medication scores were slightly higher in the XFG group than in the POAG group, although the differences were not significant. Among XFG patients, trabeculectomy was performed in 20 eyes from 16 patients (55.6%) and trabeculotomy was performed in 16 eyes from 14 patients (44.4%). Both trabeculectomy (3 eyes) and trabeculotomy (14 eyes) were performed in combination with cataract surgery. Conclusions: The XFG patients referred to our department for initial examination were older than the POAG and NTG patients, and their duration of treatment before referral was shorter. Moreover, intraocular pressure and the eye drop medication score were higher in the XFG patients. A significantly higher percentage of XFG patients required surgical intervention compared to patients with other disease types.

PURPOSE: To estimate the central 10-degree visual field of glaucoma patients using en-face images obtained by optical coherence tomography (OCT), and to examine its usefulness. PATIENTS AND METHODS: Thirty-eight eyes of 38 patients with primary open angle glaucoma were examined. En-face images were obtained by swept-source OCT (SS-OCT). Nerve fiber bundles (NFBs) on en-face images at points corresponding to Humphrey Field Analyzer (HFA) 10-2 locations were identified with retinal ganglion cell displacement. Estimated visual fields were created based on the presence/absence of NFBs and compared to actual HFA10-2 data. κ coefficients were calculated between probability plots of visual fields and NFBs in en-face images. RESULTS: Actual HFA10-2 data and estimated visual fields based on en-face images were well matched: when the test points of <5%, <2%, and <1% of the probability plot in total deviation (TD) and pattern deviation (PD) of HFA were defined as points with visual field defects, the κ coefficients were 0.58, 0.64, and 0.66 in TD, respectively, and 0.68, 0.69, and 0.67 in PD. In eyes with spherical equivalent ≥ -6 diopters, κ coefficients for <5%, <2%, and <1% were 0.58, 0.62, and 0.63 in TD and 0.66, 0.67, and 0.65 in PD, whereas for the myopic group with spherical equivalent < -6 diopters, the values were 0.58, 0.69, and 0.71 in TD and 0.72, 0.71, and 0.71 in PD, respectively. There was no statistically significant difference in κ coefficients between highly myopic eyes and eyes that were not highly myopic. CONCLUSIONS: NFB defects in en-face images were correlated with HFA10-2 data. Using en-face images obtained by OCT, the central 10-degree visual field was estimated, and a high degree of concordance with actual HFA10-2 data was obtained. This method may be useful for detecting functional abnormalities based on structural abnormalities.

Soemmerring輪を伴って発症した続発閉塞隅角症(以下、本症)の2例を経験した。症例1は78歳、男性。10年前に両眼に超音波水晶体乳化吸引術、眼内レンズ挿入術(以下、PEA+IOL)を受けた。左眼に浅前房と眼圧上昇(25mmHg)を生じ、細隙灯顕微鏡検査、および超音波生体顕微鏡(以下、UBM)所見から、本症と診断した。Soemmerring輪の手術的除去と周辺部前後嚢切開術を行い、前房深度は改善、隅角は開大し、眼圧は下降した。症例2は77歳、女性。11年前に左眼にPEA+IOLを受けた。左眼霧視と頭痛を主訴に受診した。左眼眼圧は77mmHgで浅前房と全周に周辺虹彩前癒着を認めた。同様に細隙灯顕微鏡検査、UBM所見から本症と診断し、Soemmerring輪の手術的除去と隅角癒着解離術を行った。術後、前房深度は改善し、眼圧は下降した。結論:まれではあるがPEA+IOL後の長期合併症の一つとしてSoemmerring輪を伴う続発閉塞隅角症がある。本症にはさまざまな隅角閉塞のメカニズムが関与している可能性が考えられる。診断にはUBMが有用で、正確に本症と診断された場合には、Soemmerring輪を手術的に除去することで眼内レンズを温存したまま治療できる可能性がある。(著者抄録)

OBJECTIVES: To evaluate the vascular architecture of the radial peripapillary capillaries (RPCs) and its relation with visual function in patients with open-angle glaucoma (OAG) and normal-tension glaucoma using spectral-domain optical coherence tomography (SD-OCT) angiography. SUBJECTS AND METHODS: Clear OCT angiography images of blood vessels in the optic disc and peripapillary retina were obtained from 52 patients (52 eyes) aged 55.42±10.64 (range 28-72) years with primary OAG. The mean spherical equivalent was -3.19±2.31 diopters, and the mean deviation (MD) of the central 24/30-2 threshold test using the Humphrey Field Analyzer (HFA) was -10.47±7.99 dB. The correlations between the disappearance angle of the RPCs on OTC images, flow density (FD) and the circumpapillary retinal nerve fiber layer (cpRNFL) thickness, the angle of retinal nerve fiber layer (RNFL) defect, the MD and pattern standard deviation (PSD) values of the HFA central 24/30-2 threshold test using the Swedish interactive thresholding algorithm, the sensitivity threshold, age, corneal thickness, and refractive value were analyzed. In addition, the correlation between FD and the cpRNFL thickness was analyzed at FD measurement points. RESULTS: FD was significantly correlated with cpRNFL thickness, PSD value, MD value, and sensitivity threshold, whereas the disappearance angle of the RPCs was significantly correlated with the angle of the RNFL defect (P<0.001), MD value (P<0.01), and sensitivity threshold (P<0.01). There was a negative correlation between FD and age (P<0.05). The Pearson correlation coefficient of FD and cpRNFL thickness in the area surrounding the optic disc revealed the most significant correlation in the inferior visual field (r = 0.851, P<0.001), followed by the superior visual field (r = 0.803, P<0.001) and then the temporal visual field (r = 0.653, P<0.001). CONCLUSION: SD-OCT angiography enabled thorough observation of the RPCs. FD and the disappearance angle of the RPCs were significantly and independently correlated with glaucoma-related functional and morphological changes in the optic nerve, suggesting that these two factors are novel functional and morphological indicators of visual defects due to glaucoma.

PURPOSE: We evaluated the rate of progression of total, upper, and lower visual field defects in patients with treated primary open-angle glaucoma (POAG) with high myopia (HM). SUBJECTS AND METHODS: Seventy eyes of 70 POAG patients with HM [≤-8 diopters (D)] were examined. The mean deviation (MD) slope and the upper and lower total deviation (upper TD, lower TD) slopes of the Humphrey Field Analyzer were calculated in patients with high-tension glaucoma (HTG) (>21 mmHg) versus normal-tension glaucoma (NTG) (≤21 mmHg). The mean age of all the patients (29 eyes with HTG and 41 eyes with NTG) was 48.5 ± 9.6 years. The MD slope, and upper and lower TD slopes of the HM group were compared to those of the non-HM group (NHM) (>-8 D) selected from 544 eyes in 325 age-matched POAG patients. In all, 70 eyes with HM and NHM were examined. RESULTS: The mean MD slope was -0.33 ± 0.33 dB/year in the HM, and -0.38 ± 0.49 dB/year in the NHM. There were no statistical differences between the HM and NHM (p = 0.9565). In the comparison of HTG versus NTG patients in both groups, the MD slope, and upper and lower TD slopes were similar. CONCLUSIONS: The rate of progression of total, upper, and lower visual field defects was similar among patients with HM and NHM. Although HM is a risk factor for the onset of glaucoma, HM may not be a risk factor for progression of visual field defects as assessed by the progression rate under treatment.

目的:原発開放隅角緑内障(POAG)眼で,3種の眼圧計で眼圧を測定し,中心角膜厚と角膜生体力学特性による補正値を算出し,これと中心角膜厚と年齢の相関を検索した報告。対象と方法:POAGで通院中の218例218眼を対象とした。年齢は22〜91歳,平均72歳で,圧平眼圧計による眼圧値は8〜23mmHg,平均14.8mmHgで,屈折の等価球面度数は平均-0.51±2.4Dであった。非接触眼圧計(CT-1P)による眼圧を中心角膜厚で補正した値,非接触眼圧計(7CR)による眼圧を角膜生体力学的特性を加味して補正した値,Goldmann圧平眼圧計による眼圧を中心角膜厚で補正した値につき,年齢と中心角膜厚との相関を算出した。結果:上記3方法による眼圧値とそれを補正した計6種の測定値は,いずれも年齢と負の相関があり(p=0.001〜0.0045),中心角膜厚と正の相関があった(p=0.000〜0.007)。結論:中心角膜厚または角膜生体力学的特性により補正した眼圧値には,年齢と中心角膜厚が影響し,補正が不十分である可能性がある。(著者抄録)

Purpose. To evaluate the effect on intraocular pressure (IOP) of switching from latanoprost and travoprost monotherapy to timolol fixed combinations in Japanese patients with normal-tension glaucoma (NTG). Methods. 27 NTG patients (54 eyes) were compared IOP, superficial punctuate keratitis (SPK) scores, and conjunctival injection scores in eyes treated with prostaglandin (PG) or PG analog/beta-blocker (PG/b) fixed-combination 6 months after the change in therapy. Results. The mean baseline intraocular pressure was 17.4 ± 1.59 mmHg in eyes receiving PG therapy only and 17.4 ± 1.69 mmHg in eyes switched to PG/b. Switching to fixed combination therapy from PG monotherapy, the mean IOP was 13.1 ± 1.79 mmHg (P < 0.001)  (-24.71% reduction from baseline) at 6 months. The mean conjunctival injection score was 0.69 for eyes on PG monotherapy and 0.56 for eyes on fixed combination therapy (P = 0.028). The mean SPK scores were 0.46 and 0.53. This difference was not statistically significant (P = 0.463). Conclusions. Switching from PG monotherapy to PG/b fixed combination therapy for NTG resulted in a greater intraocular pressure reduction than PG alone without increasing the number of instillations.
