Donor Corneal Endothelial Cell Maturity and Its Impact on Graft Survival in Glaucoma Patients Undergoing Corneal Transplantation. Am J Ophthalmol 2024; 262:1-9. [PMID: 38307212 DOI: 10.1016/j.ajo.2024.01.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Revised: 08/28/2023] [Accepted: 01/25/2024] [Indexed: 02/04/2024]
Abstract
PURPOSE To examine corneal graft survival via corneal endothelial cell density (ECD) and corneal endothelial cell loss (ECL) at 5 years post-transplantation in the eyes of patients with and without a history of undergoing glaucoma surgery according to the maturity of the donor corneal endothelial cells. DESIGN Prospective cohort study. METHODS This prospective cohort study included 17 patients with glaucoma and 51 patients without glaucoma who underwent Descemet's stripping automated endothelial keratoplasty or penetrating keratoplasty at the Baptist Eye Institute, Kyoto, Japan, between October 2014 and October 2016. Human corneal endothelial cells were cultured from residual peripheral donor cornea tissue, and the maturity of the cells was evaluated by cell surface markers (ie, CD166+, CD44-/dull, CD24-, and CD105-) using fluorescence-activated cell sorting. Kaplan-Meier analysis or the chi-square test was used to assess the rate of successful corneal graft survival post-transplantation. RESULTS At 36 months postoperatively, the mean ECD and ECL in the glaucoma-bleb eyes were 1197 ± 352 cells/mm2 and 55.5% ± 13.9% in the high-maturity group and 853 ± 430 cells/mm2 and 67.7% ± 18.1% in the low-maturity group, respectively. Kaplan-Meier analysis revealed that at 5 years postoperatively, the overall rate of survival was 45%, that is, 100% in the high-maturity group and 25% in the low-maturity group (P < .05). CONCLUSIONS The findings in this prospective cohort study revealed that the use of donor corneal grafts containing mature-differentiated corneal endothelial cells could maintain the survival of the transplanted graft for a long-term period, even in patients with a history of undergoing glaucoma surgery.

BMC Ophthalmol 2023; 23:509. [PMID: 38097974 PMCID: PMC10720138 DOI: 10.1186/s12886-023-03247-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Accepted: 11/27/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND To investigate the outcome of non-valved glaucoma drainage implant surgery (GDIS) in primary open-angle glaucoma (POAG) patients divided in the first GDI group (patients who underwent the first GDIS) and the second GDI group (patients who underwent the second GDIS because of the failed first GDIS). METHODS Intraocular pressure (IOP), visual acuity (VA), visual field defect (VFD), medication score (MS), survival rate of GDIS, complications, and patient background was retrospectively analyzed. Two success criteria were set: Criteria (1) IOP reduction ≥ 20% and 5 < IOP ≤ 21, Criteria (2) IOP reduction ≥ 20% and 5 < IOP ≤ 14. RESULTS There were 136 eyes of 109 patients in the first GDI group and 32 eyes of 27 patients in the second GDI group. In the first GDI group and II, mean preoperative IOP was 26.7 ± 6.7 mmHg and 23.7 ± 3.5 mmHg, respectively (P = 0.09). No statistically significant difference in postoperative IOP reduction was found between the two groups (P = 0.39). At 5-years postoperative, the Criteria 1 (Criteria 2) survival rate in the first GDI group and the second GDI group was 60.4% (31.7%) and 61.2% (25.6%), respectively (Criteria 1: hazard ratio [HR]: 0.64, 95% confidence interval [CI]: 0.30-1.35 [P = 0.24]; Criteria 2: HR: 0.81, 95% CI: 0.46-1.44, P = 0.48). No significant difference in VA, VFD change, MS, or complications was observed. Young patient age was the only significant factor for failure in the first GDI group (odds ratio: 0.95, 95% confidence interval: 0.91-1.00, P = 0.03). CONCLUSION The second GDIS may be as effective as the first GDIS for IOP reduction in POAG patients, however, there is a high risk of failure in young-age patients and the surgery may be ineffective in eyes requiring Criteria 2.

Ophthalmic Epidemiol 2022; 29:443-451. [PMID: 34311672 DOI: 10.1080/09286586.2021.1955391] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 07/03/2021] [Accepted: 07/09/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE To examine patterns of standard (trabeculectomy or glaucoma drainage devices, GDDs) vs novel (minimally invasive glaucoma surgery, MIGS) surgical techniques in the US. METHODS We used the American Academy of Ophthalmology (AAO) IRIS® Registry (Intelligent Research in Sight) queried between 2013 and 2018 (inclusive) to calculate the cumulative proportion of stand-alone, concurrent (same day) or sequential (subsequent day) glaucoma surgical techniques performed in each glaucoma diagnosis type. Secondary analyses of adjusted proportions of concurrent and sequential surgeries stratified by glaucoma diagnosis were also performed. RESULTS Of 203,146 eyes receiving glaucoma surgeries, open angle glaucoma (OAG) was most likely to undergo all types of intervention. The iStent was the most commonly performed MIGS, primarily for those with normal tension glaucoma (NTG) or OAG (p < .001). Conversely, GDD was the most commonly performed procedure in secondary glaucoma or other (specified) glaucoma (p < .001). ECP and iStent were the most common concurrent procedures performed; most often for OAG and NTG (p < .001). After an initial standard surgery, most eyes underwent recurrent standard interventions (90.3%). ECP was the most common MIGS performed after an initial standard surgery; particularly in primary angle-closure (PACG) and secondary glaucoma eyes (p < .001). CONCLUSION Glaucoma type may influence the choice of glaucoma procedures and the decision to perform concurrent as well sequential surgical procedures. Given the poorly understood long term safety and effectiveness of MIGS, and with substantially increasing use of MIGS procedures in recent years, future studies comparing their safety and effectiveness vs standard interventions, for a variety of glaucoma types, is needed.

Abstract
PRCIS Tube shunt implantation through the pars plana was effective for neovascular glaucoma (NVG) for at least 3 years, with few serious postoperative complications observed. PURPOSE The aim was to report 3-year outcomes of pars plana Ahmed and Baerveldt glaucoma implantation for NVG in Japanese eyes. PATIENTS AND METHODS This study examined 41 eyes of 39 patients who underwent tube shunt implantation through the pars plana with the Baerveldt glaucoma implant (BGI group, 26 eyes) or Ahmed glaucoma valve (AGV group, 15 eyes) for NVG and who were followed up for over 3 years at Osaka Medical College between January 2009 and April 2016. Outcome measures were intraocular pressure (IOP, mm Hg) at presurgery and at 6 months and 1, 2, and 3 years postoperative. Postoperative failure was defined as an IOP of >21 mm Hg or <5 mm Hg, further glaucoma surgery, or no light perception. RESULTS Mean IOPs at presurgery and at 3 years postoperative were 34.8±9.1 and 15.6±4.6 in the AGV group, and 36.9±9.2 and 12.8±5.5 in the BGI group. Mean antiglaucoma medication scores at 3 years postoperative were 1.3±1.4 in the AGV group and 0.4±0.8 in the BGI group (P=0.05). The number of eyes with a probability of failure at 6 months and at 2 and 3 years postoperative was 2, 3, and 4, respectively, in the BGI group, and 0, 1, and 2, respectively, in the AGV group. CONCLUSION Findings for NVG cases showed tube shunt implantation through the pars plana was effective. Equivalent good IOP reductions were noted in both groups, with the BGI group requiring fewer postoperative antiglaucoma medications compared with the AGV group. Furthermore, both groups exhibited few serious postoperative complications.

Microangiopathy in Ocular Sarcoidosis Using Fluorescein Gonio and Fundus Angiography from Diagnostic and Therapeutic Aspects. Diagnostics (Basel) 2020; 11:diagnostics11010039.

Abstract
In this retrospective study, we investigated vascular abnormalities in sarcoidosis using fluorescein gonioangiography (FGA) to detect angle neovascularization (ANV), fundus fluorescein angiography (FFA), and pathological specimens from the aspects of microangiopathy. In 57 sarcoidosis patients, clinical data was reviewed by dividing the cases into three groups (Group I: histologically diagnosed; Group II: positive bilateral hilar lymphadenopathy (BHL); Group III: negative BHL). The FFA, FGA, and pathological examination data in the autopsy eyes and trabeculectomy specimens were investigated. FGA and FFA detected ANV (91%) and nodule-associated abnormalities (87%), respectively. No intraocular pressure (IOP) elevation was observed after continuous topical betamethasone, except in the steroid responder group. Maximum IOP had significant correlation with nodules in the angle (p = 0.02696) and visual field defect (p = 0.0151). Granulomas adjacent to blood vessels, including the Schlemm’s canal, and thickening of the retinal blood vessel wall caused occlusion of those vessels. Photocoagulation was required for retinal tears (14%) and the retinal blood vessel occlusion (7%). Suppression of IOP elevation via continuous topical betamethasone may be important to avoid irreversible outflow-route changes and optic-nerve damage, and the concept of microangiopathy in ocular sarcoidosis may be important for understanding the proper treatment of serious complications.

Abstract
PURPOSE To evaluate the efficacy of long-tube shunt surgery (LTSS) without valve in uveitic glaucoma (UG) eyes. METHODS We retrospectively analyzed the data of 45 UG eyes that underwent only LTSS or LTSS combined with trabeculectomy (TLE) (LTSS/TLE). The UG eyes were analyzed by categorizing them into granulomatous/non-granulomatous, steroid responder/non-responder, and primary open-angle glaucoma (POAG) (POAG background)/non-POAG (non-POAG background). All granulomatous UG eyes received a continuous 3-times-daily administration of topical betamethasone post-LTSS. RESULTS The eyes consisted of granulomatous (37 eyes, 82%)/non-granulomatous (5 eyes, 11%), steroid responder (19 eyes, 42%)/non-steroid responder (13 eyes, 29%), and 20 eyes with POAG or POAG background (p = 0.0022, 83%) among 24 cases of unilateral UG. The 5-year survival rates of only LTSS and LTSS/TLE were 66% and 100%, respectively. Kaplan-Meier survival-curve estimates in the non-granulomatous group were 100% for 6-year postoperative period, while the granulomatous group showed a gradual decrease along the 6-year (81%) postoperative period. The 5-year survival rates in the steroid responder group and the non-steroid responder group eyes were 74% and 78%, respectively. No intraocular pressure (IOP) elevation was observed in the positive steroid responder eyes post-LTSS. CONCLUSIONS LTSS and LTSS/TLE were both effective in UG. Positive steroid response may be masked by LTSS in the positive responder eyes. Continuous administration of topical betamethasone post-LTSS may be important for preventing an IOP spike by suppressing inflammation in the anterior chamber. LTSS combined with TLE may be recommended in eyes with granulomatous UG, and the coexistence of a POAG/POAG background.

Abstract
BACKGROUND/AIM Glaucoma is a chronic and progressive optic neuropathy which leads to deterioration of visual function. It is estimated to be the second leading cause of severe vision loss and blindness worldwide. Failure of anti-glaucoma medication to sufficiently reduce intraocular pressure (IOP) and poor compliance with medication are indications for glaucoma surgery, for example using glaucoma drainage devices. Our aim was to compare the surgical outcomes following the implantation of Ahmed FP7 and Baerveldt 350 drainage devices. PATIENTS AND METHODS Five hundred and fifty-two patients with primary or secondary glaucoma were enrolled in the study. All patients had a history of failed trabeculectomy or other intraocular surgery, and IOP ≥18 mm Hg. The implantation of Ahmed (266 patients) or Baerveldt (286 patients) devices was randomly performed in the patients, who were subsequently examined for a period of 5 years. Follow-up visits were scheduled 1 day; 1 week; 1, 3 and 6 months; and 1, 1.5, 2, 3, 4 and 5 years postoperatively. RESULTS Significant reduction of IOP was achieved in both groups. Ahmed valve (28.3±9.3, 13.4±6.9, 14.2±6 and 12.7±4.5 mmHg at baseline, 1, 3, and 5 years postoperatively, respectively) resulted in significantly greater IOP reduction compared to Baerveldt implant (29.6±10.1, 15.4±5.5, 14.5±5.5 and 14.7±4.4 mmHg at baseline, 1, 3, and 5 years postoperatively, respectively). A significantly lower number of medications was required in the Ahmed group in comparison to the Baerveldt one (Ahmed group: 1.5±1.4, 1.4±1.5 and 1.8±1.5; Baerveldt group: 1.9±1.3, 1.9±1.3 and 2.2±1.4, respectively). The incidence of treatment failure and the rate of glaucoma reoperation were significantly higher in the Baerveldt group (40%) compared to the Ahmed group (17%). CONCLUSION Ahmed drainage implantation seemed to outclass that using the Baerveldt device in our study, in terms of efficacy and success rate.

Abstract
PURPOSE We compared the outcomes of Baerveldt glaucoma implant (BGI) surgery between vitreous cavity and anterior chamber insertion. METHODS We retrospectively analyzed a total of 105 consecutive eyes that underwent BGI surgery and were followed up for ≥ 12 months. BGI surgery was performed via the anterior chamber (AC group 48 eyes) or the pars plana into the vitreous cavity (VC group 57 eyes). Patients' data were examined at 3, 6, and 12 months, and then every 6 months after surgery. We compared the groups' intraocular pressure (IOP), success ratio, visual acuity, number of glaucoma medications, central corneal endothelial cell density (CCECD), reduction ratio of CCECD, and postoperative complications. RESULTS The mean preoperative and postoperative IOP values were not significantly different between the two groups. In the Kaplan-Meier survival plots, there was no significant between-group difference in the success rate (p = 0.333). The postoperative mean CCECD decreased significantly faster in the AC group than the VC group at all time points. The cases of postoperative corneal edema were 12.5% in AC group and 1.8% in VC group. The risk of postoperative corneal edema was significantly higher in the AC group (p = 0.0136). Risk factors for the rapid reduction of CCECD were "history of trabeculectomy" (p = 0.00283), "insertion into the anterior chamber" (p = 0.001), and "shorter distance between the tube and corneal endothelium" (p = 0.0137). CONCLUSION There was no significant between-group difference in postoperative IOP, medications, or success rate. Considering the reduction of corneal endothelial cells, insertion into the vitreous cavity seems safer than insertion into the anterior chamber.

Abstract
Objective: To investigate the early postoperative complications in two different tube ligation methods during the first 3 months in Baerveldt implant surgery. Participants: This study involved 157 eyes from 144 patients who underwent Baerveldt Implant Surgery at the Japanese Red Cross Medical Center, Tokyo, Japan. Methods: Pre- and postoperative intraocular pressure (IOP), combined surgery, postoperative time-point of tube ligation release, and postoperative complications in two different tube ligation methods [absorbable ligation method using 8-0 polyglactin suture (group A) and nonabsorbable ligation method using 7-0 nylon suture (group B)] were retrospectively reviewed. Results: After excluding eyes that had undergone combined trabeculectomy (26 eyes) and vitrectomy (2 eyes), eyes with previous tube surgery (22 eyes), and eyes that had undergone the stent method (1 eye), 30 of 28 patients in group A and 71 eyes of 71 patients in group B were found to fit the criteria of this study. The rate of successful surgical outcome was 80% in group A and 74.6% in group B (p = 0.705). During the 3 months postoperative, high IOP tended to occur more often in group B (67.6%) than in group A (46.7%) (p = 0.073), and ciliochoroidal detachment tended to occur more often in group A (10.0%) than group B (2.8%) (p = 0.154). Conclusion: The results of this study show that both ligation methods are effective, however, the selection of tube ligation method should be done in accordance with the different method-specific risks to which may occur.
