RESUMEN
PRCIS: Phaco-GSL demonstrates promise in safely and efficiently managing advanced PACG cases with tunnel vision or limited temporal visual field. However, caution is advised for patients with only one functioning eye or high visual expectations. PURPOSE: To assess the efficacy and safety of phacoemulsification with goniosynechialysis (phaco-GSL) in patients with end-stage primary angle-closure glaucoma (PACG) exhibiting tubular vision or temporal field island. METHODS: This retrospective study evaluated 68 patients (74 eyes) diagnosed with advanced PACG and exhibiting either tubular vision or temporal field island. All patients underwent phaco-GSL and were monitored for at least one month postoperatively. The study analyzed changes in visual acuity (VA), intraocular pressure (IOP), medication use for anti-glaucoma, and postoperative complications. RESULTS: The mean follow-up time was 9.11±10.49 months. The mean preoperative visual field deviation and VA were -28.01±3.30 dB and 0.36±0.37 logMAR unit, respectively. Postoperatively, the VA for over half (54.1%) of the eyes increased, 29.7% remained unchanged, and 16.2% worsened. The final IOP decreased significantly from 24.65±8.61 to 14.81±3.54 mmHg. Glaucoma medication use also reduced from 1.46±1.43 to 0.88±1.18. The success rate was 48.6% for complete and 89.2% for qualified. IOP spikes (27.0%) and wipe-out (8.1%) were the most common postoperative complications. Vision recovered gradually in five of six wipe-out patients. One eye (1.4%) developed permanent vision loss with VA decreasing to hand motion. CONCLUSION: Phaco-GSL appears safe and effective in treating advanced PACG cases with tubular vision or temporal field island. However, caution is warranted when considering this treatment option for patients at high wipe-out risk or those with high expectations for visual outcomes.
RESUMEN
INTRODUCTION: To analyze the correlation between orbital compliance and retinal vessel density (VD) based on dynamic Scheimpflug analyzer (Corvis ST) and optical coherence tomographic angiography (OCT-A). METHODS: In this prospective observational study, 65 eyes of 44 patients with thyroid-associated ophthalmopathy (TAO) in quiescent stage were included (15 males and 29 females). The whole eye movement (WEM) was detected by Corvis ST. The superficial capillary plexus VD (SCP-VD) and deep capillary plexus VD (DCP-VD) were obtained by scanning the 3 × 3 mm area around the fovea using OCT-A, while the peripapillary vessel density (ppVD) was obtained by scanning the 4.5 × 4.5 mm area around the optic disk. Covariances including biomechanically corrected intraocular pressure (bIOP), axial length, age and gender were adjusted during data analysis. RESULTS: The mean WEM of the participants was 0.235 ± 0.066 mm. The mean SCP-VD and DCP-VD in whole image were 46.20% ± 3.77% and 50.51% ± 3.96%; the mean whole pp-VD was 49.75% ± 2.01%. WEM was positively correlated with SCP-VD (r = 0.327, p = 0.01) and the whole pp-VD (r = 0.394, p < 0.01) after adjusting by gender, axial length (AL), age and bIOP, but it was not significantly correlated with DCP-VD (r = 0.072 p = 0.581). CONCLUSION: Increase in orbital pressure might reduce retinal microvascular perfusion. Our data suggest orbital mechanical compression may be an important cause of retinal VD changes in quiescent patients with TAO.
RESUMEN
AIM: To evaluate whether a novel tyrosine kinase inhibitor nintedanib could inhibit basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) simultaneously for retinal vascular disease in vivo. METHODS: After a laser induced rabbit retinal vein occlusion (RVO) model was made, 0.5 mg of nintedanib was injected intravitreally in the left eye on the third day while the right eye was as a control. Intracameral samples were taken on the day before laser treatment and days 1, 3, 7, 14, 21, and 28 after treatment. Enzyme-linked immunosorbent assay (ELISA) was used to test the bFGF and VEGF-A concentrations in the aqueous humor. RESULTS: Both bFGF and VEGF-A rose significantly on the third day after laser treatment in both eyes. In the control eye the bFGF concentration peaked on the 14th day while the VEGF-A concentration dropped rapidly soon after the third day. After nintadanib injection in the study eye, both bFGF and VEGF-A showed a significant reduction on the 4th day (7th day after laser treatment) when compared to the control eye, and kept on low level in the following several weeks. CONCLUSION: Intravitreal injection of nintedanib can inhibit the expression of bFGF and VEGF in the process of RVO model to a certain extent, which is expected to become a new method for the treatment of retinal vascular diseases or fibrotic diseases.
RESUMEN
AIM: To observe the imaging features of color Doppler ultrasound (CDU) and computed tomography (CT) or computed tomography dacryocystography (CT-DCG) in different types of lacrimal sac space-occupying lesions (SOLs). METHODS: This retrospective case series study included 21 patients with lacrimal sac SOLs who underwent lacrimal sac surgery between January 2018 and March 2022. The imaging features of CDU and CT or CT-DCG in these patients were extracted from the examination cloud system. The images were observed and analyzed. RESULTS: The detection rate of lacrimal SOLs between CDU (21/21, 100%) and CT or CT-DCG (20/21, 95.2%) had no statistically significant difference (P=1.0). CDU could detect the blood flow signals in all SOLs except mucocele and mucopeptide concretion. Among them, polyps had characteristic imaging changes on CDU and CT-DCG. The mucoceles and mucopeptide concretions had characteristic imaging changes on CDU, which could provide more information for differential diagnosis. CONCLUSION: The morphology and internal blood flow signals of lacrimal sac SOLs can be observed using CDU. CT or CT-DCG has advantages in observing structural damage around the lacrimal sac mass. Therefore, CDU may be used as a routine examination to exclude lacrimal sac SOLs before dacryocystorhinostomy in the absence of preoperative CT or CT-DCG.
RESUMEN
PRCIS: Phacoemulsification and goniosynechialysis (Phaco-GSL) was equally effective in the treatment of primary angle-closure disease (PACD) with preoperative peripheral anterior synechiae (PAS) <180 degrees and larger than 180 degrees. Patients with a larger preoperative PAS range required more range of mechanical separation intraoperatively and displayed more recurrence of PAS (re-PAS) range postoperatively. PURPOSE: To evaluate the long-term efficacy of combined phaco-GSL in PACD with different extent of PAS. PATIENTS AND METHODS: A retrospective study was conducted on 67 patients (79 eyes) who received phaco-GSL. The patients were divided into 2 groups according to the extent of PAS (group A: PAS ≤180 degrees; group B: PAS >180 degrees). Changes in intraocular pressure (IOP), the number of anti-glaucoma drugs, intraoperative mechanical separation of PAS and range of re-PAS during the last follow-up ≥12 months were analyzed. RESULTS: At baseline, eyes in group B presented with higher IOP and more anti-glaucoma drugs usage ( P =0.008 and 0.004). The PAS range, IOP, number of anti-glaucoma medication were reduced both in 2 groups at the final visit. The range of mechanical separation intraoperatively and re-PAS postoperatively were both larger in group B ( P =0.002 and <0.001). The postoperative re-PAS range was positively correlated with the range of mechanical separation ( R2 =0.17). The complete success rates at 12, 24, 36, and 48 months were 86.8%, 71.1%, 71.1%, and 71.1% in group A; and 80.5%, 74.6%, 69.9%, and 69.9% in group B. The qualified success rates were 100%, 96.6%, 92.0%, and 92.0% in group A; and 100%, 89.5%, 85.1%, and 85.1% in group B. CONCLUSION: Phaco-GSL for the treatment of PACD showed equally effective IOP control regardless of the extent of preoperative PAS.

AIM: To evaluate the accuracy and predictability of ray tracing-assisted intraocular lens (IOL) calculation function in Sirius internal software and further improve the accuracy by optimizing the calculation of predicted lens position (PLP). METHODS: This retrospective study recruited 52 eyes of 49 patients. All of the cases with cataract had undergone phacoemulsiï¬cation combined with IOL implantation. SRK-T, Haigis formula, and Sirius ray-tracing method were all used for each eye's IOL calculation. The mean absolute value of prediction error (prediction error=predicted refraction-postoperative refraction) was defined as mean absolute prediction error (MAPE) and was determined for each method. Calculation of PLP was optimized by effective lens position (ELP). Optimized PLP was entered to Sirius internal software again to verify whether the method was improved. RESULTS: Compared with SRK-T and Haigis formulas, less accuracy was shown in Sirius ray-tracing method (P=0.001). The ELP of the IOL moved forward compared to PLP (P<0.001). The MAPE of the ELP-inputted Sirius ray-tracing method was reduced. ELP and PLP were well correlated. Taking ELP as y and PLP given by Sirius soft as x, a linear regression formula y=0.1637x+3.1741 was concluded (R2 =0.1066, P=0.018). It was shown that the optimized Sirius ray-tracing method (optimized PLP entered), compared with SRK-T and Haigis formulas, worked with the same accuracy (P=0.038). CONCLUSION: The original Sirius ray tracing method is not satisfactory enough. However, in normal eyes, the optimized Sirius ray-tracing method in IOL calculation was as accurate as SRK-T and Haigis formulas.
RESUMEN
AIM: To observe whether silicone oil (SO) tamponade could decrease macular perfusion after retinal detachment repair. METHODS: A prospective observational case-control study. Patients diagnosed with primary macular off rhegmatogenous retinal detachment undergoing successful retinal repair surgery with vitrectomy were strictly selected. Optical coherence tomography angiography findings were compared between SO and air tamponade groups. Two postoperative visiting points were set (1 and 3mo). RESULTS: Totally 29 patients (29 eyes) were enrolled. Twenty cases had SO tamponade while 9 cases were with air tamponade. At the first visiting point, superficial parafoveal vessel density (PFSVD) significantly decreased in the SO group (P=0.0403), especially in the superior quadrant or superior-hemi area (P=0.0089, 0.0426, respectively). Parafoveal deep vessel density (PFDVD) had no difference between the two groups. At the second visiting point, all quadrants of PFSVD reduced significantly in the SO group (P=0.0256, 0.0001, 0.0031, <0.0001 in temporal, superior, nasal, and inferior area, respectively), but PFDVD remained no different. In the air group, all areas of PFSVD showed significantly improving from the first visit to the second one (P=0.0324, 0.0001, 0.0371, 0.0026, in temporal, superior, nasal, and inferior area, respectively); however, almost all quadrants of PFDVD showed no changes during this period. In the SO group, both PFSVD and PFDVD showed no obvious changes between the two visiting points. Besides, parafoveal full retinal thickness in the SO group reduced significantly at both visiting points over the air tamponade, while the foveal avascular zone area showed no difference in the two groups. CONCLUSION: After retinal detachment surgery with vitrectomy and SO tamponade, superficial macular perfusion and full retinal thickness could decrease obviously when compared to air tamponade. This reduction process could persist throughout the tamponade period.
RESUMEN
PURPOSE: To evaluate the efficacy and risk of cataract surgery (phacoemulsification with intraocular lens [IOL] implantation) combined with endoscopic goniosynechialysis (EGSL) for advanced primary angle-closure glaucoma (PACG). DESIGN: Retrospective, continuous case series. PARTICIPANTS: A total of 16 patients (18 eyes) with advanced PACG were enrolled in this study between February 2014 and March 2016. Advanced glaucoma inclusion criteria were based on the method proposed in the Advanced Glaucoma Intervention Study, with a visual field score of 18 points or more. METHODS: All patients underwent cataract surgery with EGSL by the same experienced surgeon. Paired t test and generalized estimating equation analyses were performed. MAIN OUTCOME MEASURES: The extent of peripheral anterior synechiae (PAS), number of intraocular pressure (IOP)-lowering drugs, IOP, best-corrected visual acuity (BCVA), and visual fields before and after surgery. The incidence of complications was recorded. RESULTS: The mean follow-up duration was 13.8 months (standard deviation, 2.7 months). The mean difference (preoperative minus postoperative) in PAS was 202.7° (95% confidence interval [CI], 43.5°). The mean difference (preoperative minus postoperative) in the number of IOP-lowering drugs and IOP was 2.0 (95% CI, ±0.5), and 9.4 mmHg (95% CI, ±2.1 mmHg) respectively. The mean improvement in BCVA was 0.29 logMAR (95% CI, ±0.14). A positive correlation was found between the extent of postoperative PAS and postoperative IOP (B = 8.2; P < 0.001) and also between postoperative PAS and postoperative number of IOP-lowering drugs (B = 28.9; P < 0.001). Anterior chamber hemorrhage and exudation occurred in 4 patients and 2 patients, respectively, after surgery. Posterior capsular opacification occurred in 5 patients after surgery. CONCLUSIONS: Cataract surgery with EGSL could be an effective surgical method for the treatment of advanced PACG.

PURPOSE: To evaluate two different approaches of anterior vitrectomy combined with hyaloidotomy, zonulectomy, and iridectomy (VHZI) for fluid misdirection syndrome (FMS) secondary to phacoemulsification with intraocular lens implantation combined with goniosynechialysis (phaco-IOL-GSL). METHODS: Nine patients with FMS who developed after a phaco-IOL-GSL procedure, were retrospectively studied from May 2015 to February 2018. They were treated with VHZI, in which 5 cases underwent local anterior vitrectomy via anterior chamber approach, and the others underwent comprehensive vitrectomy via pars plana approach. Main outcome measures were pre- and postoperative intraocular pressure (IOP), number of antiglaucoma medications, and relapse rate. RESULTS: Incidence of FMS secondary to phaco-IOL-GSL was 1.4% (9 in 652 eyes), which was promptly resolved in all affected cases. VHZI via anterior chamber approach resulted in a significant decrease in the mean IOP from 40.2 ± 9.7 mm Hg at presentation to 15.2 ± 4.8 mm Hg postoperatively (P=0.01). The median number of antiglaucoma medications reduced from 3 to 2 (P=0.066). Meanwhile, VHZI via pars plana approach also resulted in the reduction of the mean IOP values from 26.0 ± 5.7 mm Hg at presentation to 15.2 ± 3.3 mm Hg postoperatively (P=0.092). The median number of antiglaucoma medications also reduced from 3.5 to 1.5 (P=0.059). Relapse rate of the treatment through pars plana approach (0%, 0/4) was much lower than that through anterior chamber approach (40%, 2/5), although the difference was not statistically significant (P=0.444). CONCLUSIONS: FMS is a rare but severe complication secondary to phaco-IOL-GSL. Compared to VHZI with local anterior vitrectomy via anterior chamber approach, VHZI with comprehensive anterior vitrectomy via pars plana approach might be a more effective procedure to treat FMS. The study has been registered in Contact ClinicalTrials.gov PRS Identifier: NCT04172857.
RESUMEN
PURPOSE: To investigate feasibility of endoscopic endonasal dacryocystorhinostomy (EE-DCR) with an novel lacrimal ostium stent (LOS) intubation for patients with chronic dacryocystitis with small lacrimal sac. METHODS: Patients diagnosed as chronic dacryocystitis with small lacrimal sac who preferred to surgery treatment between March 1st, 2012 and May 1st, 2015. All included subjects were randomly divided into 2 groups (Group A and Group B). Cases in group A were performed EE-DCR with LOS intubation while cases in group B were underwent EE-DCR without LOS intubation. Demographic data of each cases were collected. The success rate and the surgical outcomes of 2 groups were compared. RESULTS: The success rate was much higher in group A than group B. At 3 months follow up, 61.6% of patients in group A exhibited scarring and/or granulation tissues around the ostium, which was significantly higher than the 36.4% of patients in group B. Of these patients with scars and/or granulation tissues, no statistical difference was found between 2 groups. Granuloma alone and scars with granuloma were observed in 10 patients and 2 patients, in group A and group B, respectively, resulting in a statistical significant difference for this outcome between the groups. At 9 months follow up and 12 months follow up, no significant statistical difference were found in the rate of scarring and/or granulation tissues, scars alone, granuloma alone and scars with granuloma between 2 groups. CONCLUSIONS: EE-DCR with novel LOS may be an effective procedure to manage chronic dacryocystitis with small lacrimal sac.

BACKGROUND: To investigate the occurrence of ciliochoroidal detachment (CCD), its risk factors and its impact on the success rate after Ahmed glaucoma valve (AGV) implantation. METHODS: This is a retrospective observational study carried out at Eye Hospital of Wenzhou Medical University, Zhejiang, China. Patients with uncontrolled glaucoma who underwent AGV implantation alone or combined with phacoemulsification (AGV-Phaco) in the hospital from April 1, 2013 to July 31, 2016 were included. The preoperative and postoperative CCD was defined when the detachment between ciliary body and choroid was detected by the ultrasound biomicroscopy (UBM) and anterior segment optical coherence tomography (AS-OCT) respectively. The main outcomes included the incidence of CCD and the success rate at 6 months after surgery. RESULTS: In total, 97 male and 56 female patients were included. CCD was observed in 92 (57.8%) eyes. The glaucoma diagnosis in the Non-CCD and CCD group included primary open angle glaucoma (21(31.3%) vs 33(35.9%)), primary angle closure glaucoma (10(14.9%) vs 13(14.1%)), secondary glaucoma (25(37.3%) vs (28(30.4%)) and so on. The preoperative median IOP (interquartile range) were 21.7(16.0,32.0) mmHg and 23.0(16.0,33.0) mmHg in the Non-CCD group and CCD group. Previous surgical history (95% confidence interval (CI), 1.24 to 13.34; odds ratio (OR) 4.06; p = 0.02) and shorter axial length (95% CI, 0.62 to 0.97 OR 0.78; p = 0.02) were the two risk factors of CCD. The success rate between the CCD and Non-CCD group was not significantly different (64.3% vs 62.5%, p = 0.86) at 6 months. CONCLUSIONS: The incidence of CCD is 57.8% after AGV surgery. Eyes with previous surgical procedure was prone to CCD occurrence and longer axial length was protective against CCD. But at 6 months postoperatively, CCD did not reduce the success rate of AGV surgery and may not be a worrisome complication.

PURPOSE: To investigate the clinical efficacy and safety of combined phacoemulsification with goniosynechialysis (GSL) under an ophthalmic endoscope for chronic primary angle-closure glaucoma and coexisting cataract. METHODS: This is a retrospective study. The intraocular pressure (IOP), best-corrected visual acuity (BCVA), and number of glaucoma medications at baseline and each postoperative follow-up visit were recorded. Other measurements included supraciliochoroidal fluid measured by anterior segment optical coherence tomography, corneal endothelial cell density (ECD), and peripheral anterior synechia (PAS). All patients were followed for more than a year. RESULTS: Thirty-eight eyes of 31 patients were included. The mean follow-up duration was 16.3 ± 3.9 months. The IOP decreased from 22.2 ± 9.3 mmHg at baseline to 15.4 ± 4.2 mmHg at the last follow-up (P < 0.001). The mean number of glaucoma medications (0.1 ± 0.6) at the last follow-up was significantly lower than the preoperative number (2.3 ± 1.1) (P < 0.001). All patients achieved improved or stable visual acuity after surgery. All patients achieved a complete opened angle after GSL. The postoperative complications included hyphema (7.9%), exudation (5.3%), transiently elevated IOP (55.3%), and supraciliochoroidal fluid (40%). CONCLUSIONS: Combined phacoemulsification and GSL under an endoscope can completely reopen PAS and is an effective and safe method for patients with chronic primary angle-closure glaucoma and coexisting cataract.
RESUMEN
OBJECTIVE: To correlate the intraoperative endoscopic findings with high-resolution CT (HRCT) for the diagnosis of optic canal fractures (OCF). To compare the visual outcome of patients with different types of OCF and without. DESIGN: A retrospective, comparative case series. PARTICIPANTS: 1275 consecutive patients (1275 eyes) with indirect traumatic optic neuropathy (TON). METHODS: Altogether, 1275 patients who underwent endoscopic transethmoid optic canal decompression (ETOCD) for unilateral indirect TON were reviewed from 1 October 2006 to 30 September 2014. HRCT performed prior to surgery were compared with findings during surgery. The visual outcomes before and after surgery were also compared. MAIN OUTCOME MEASURES: The presence and type of OCF detected by HRCT and during surgery; visual acuity prior to surgery and at 3â months after surgery. RESULTS: A total of 1275 patients (1275 eyes) were included, with 708 patients that had OCF visible on HRCT image. During surgery, an additional 187 (20.9%) patients with OCF were noticed. Among these, 136 had undisplaced fractures, most of which were linear intracanalicular fractures. The initial visual acuity of patients with OCF was worse than that of patients without OCF (p<0.01). However, no statistical difference existed in the final visual acuity at 3â months after surgery (>0.05). Significant statistical difference of surgical efficacy existed between all the patients with OCF and without OCF (p<0.001). CONCLUSIONS: Among patients with OCF, 20.9% were not detected by HRCT. Patients with OCF had a worse initial visual acuity than those without OCF. There was no significant difference in final visual acuity after ETOCD.

PURPOSE: The purpose of this article is to describe a modified lacrimal bypass with a porous polyethylene-coated Jones tube. METHODS: A total of 180 patients (180 eyes) with a nonreconstructable lacrimal obstruction underwent lacrimal bypass with a porous polyethylene-coated Jones tube through a retrocaruncular-middle meatus tract approach with endoscopic assistance. All patients were followed up at least for 24 months. Success rate of lacrimal bypass was analyzed and complications were recorded. RESULTS: A total of 174 patients were finally included. Duration of surgery ranged from 28 to 47 minutes (mean 37.2â±â4.2 minutes). The mean duration of follow-up was 30.0â±â6.4 months (range 24-48 months). The mean tube length was 23.2â±â1.9âmm (range 20-28âmm). At the final review, complete success was achieved in 138 (79.3%) patients. Moderate success was achieved in 23 (13.2%) patients, and 13 (7.5%) patients failed. Of the 161 patients successfully treated, 24 patients underwent revision surgery to excise granulomas (15 patients) or adjust tube position (9 patients). The complications included granuloma proliferation around the openings of the tube (28 eyes), downward displacement of the tube (17 eyes), and ocular discomfort (15 eyes). The majority of downward tube migration occurred in patients who had a prior history of dacryocystorhinostomy. The treatment failed for 5 patients because of repeated granulomas covering the nasal tube openings, and the treatment failed for 8 patients because of downward displacement of the tube. CONCLUSIONS: Our procedure appears to be an effective method for closed insertion of a porous polyethylene-coated Jones.

Lacrimal sump syndrome is an uncommon cause of failed dacryocystorhinostomy. Small osteotomy was reported as the major cause of this syndrome. Here, the authors described the first case of a lacrimal sump syndrome with a large intranasal ostium following endoscopic endonasal dacryocystorhinostomy (EE-DCR). A 51-year-old women patient suffered recurrence of epiphora and dacryocystitis for 8 months following an EE-DCR. Examination showed a large intranasal ostium with a lot of purulent discharge and patent lacrimal irrigation. Lacrimal sump syndrome was diagnosed after passing a probe into the residual lacrimal sac under the aid of an endoscope. The residual sac was reopened and merogel was packed around the wound. The clinical symptoms disappeared after the surgery. It is indicated that lacrimal sump syndrome does happen not only in a small intranasal ostium, but also in a large intranasal ostium. Existing residual sac with bacterial infection may be related to this particular case.

Purpose. The aim of this study is to propose a simple and efficient combination surgery for the management of dacryocystitis with canalicular obstruction. Methods. A retrospective noncomparative case series of dacryocystitis with canalicular obstruction has been studied. Twelve patients with dacryocystitis and canalicular obstruction underwent a conventional endoscopic endonasal dacryocystorhinostomy (EE-DCR) combined with a modified canalicular repair. Postoperative observations included slit lamp, fluorescein dye disappearance test, lacrimal syringing, lacrimal endoscopy, and nasal endoscopy. Results. After 6-18 months of postoperative follow-up, the symptoms of epiphora and mucopurulent discharge disappeared completely in 10 patients, and occasional or intermittent epiphora remained in 2 patients. All of the twelve patients showed an opened intranasal ostium and normal fluorescein dye disappearance test. Patent bicanalicular irrigation was achieved in 9 patients. One patient had a partial and the other two had a complete reobstruction by lacrimal irrigation to their repaired lower canaliculus; however, all of them had a patent lacrimal irrigation to upper canaliculus. The functional success rate for the combination surgery is 83% (10/12), and anatomical success rate is 75% (9/12). Conclusion. EE-DCR combined with modified canalicular repair is a simple and efficient method for the management of dacryocystitis with canalicular obstruction.
