ABSTRACT
PURPOSE: To retrospectively evaluate the 3-year efficacy and safety of single-agent omidenepag isopropyl in patients with normal tension glaucoma (NTG). STUDY DESIGN: Retrospective. METHODS: One hundred patients (100 eyes) who had newly been administered omidenepag isopropyl were enrolled in this study. Intraocular pressure (IOP) was compared at baseline and 6, 9, 12, 18, 24, 30, and 36 months after administration. The mean deviation values at baseline and 12, 24, and 36 months measured using the Humphrey visual field test (30-2 Swedish Interactive Threshold Algorithm standard) were compared. Adverse reactions and dropouts were assessed. RESULTS: IOP significantly decreased from 15.5±2.7 mmHg at baseline to 13.8 ±2.3 mmHg after 6 months, 13.9± 2.3 mmHg after 12 months, 13.9±2.3 mmHg after 18 months, 13.8±2.1 mmHg after 24 months, 13.9±2.0 mmHg after 30 months, and 13.6±1.7 mmHg after 36 months (P < 0.0001). There was no significant difference in the mean deviation values at baseline (-3.66±3.49 dB), 12 months (-3.41±3.80 dB), 24 months (-3.13±3.81 dB), and 36 months (-3.06±3.30 dB). Adverse reactions occurred in 11 patients (11.0%), including conjunctival hyperemia in 6 patients. Fifty-two patients (52.0%) were excluded from the analysis because they discontinued treatment either due to IOP measurement by NCT or the use of additional drugs. CONCLUSION: After the administration of omidenepag isopropyl, IOP in patients with NTG decreased within 3 years, visual fields were maintained, and safety was satisfactory. Thus, omidenepag isopropyl can be used as the first-line treatment for patients with NTG.

PURPOSE: Relentless placoid chorioretinitis (RPC) is a new disease concept that was proposed by Jones et al. in 2000. Some cases of RPC have been reported; however, a treatment strategy has not yet been established. We report herein four cases of patients diagnosed with RPC. OBSERVATIONS: We experienced four cases of RPC in patients aged 24-51 years. All patients exhibited retinal lesions similar to that seen in acute posterior multifocal placoid pigment epitheliopathy or serpiginous choroiditis from the posterior pole to the surrounding region. Although patients underwent systemic prednisolone (PSL) therapy, recurrence was observed and the retinal scar formation was progressive; they were then diagnosed with RPC. In all cases, cyclosporine (CyA) was administered in addition to PSL, no recurrence was observed thereafter. CONCLUSIONS AND IMPORTANCE: RPC is a rare disease, and a treatment strategy has not yet been established. CyA and PSL combination therapy is considered to be effective in the treatment of RPC.
ABSTRACT
BACKGROUND/AIM: Although flow cytometry (FCM) is used to evaluate cell surface markers of various leucocyte populations quantitatively, little is known about the usefulness of FCM in lymphoproliferative disorders of the ocular adnexa. The aim of this study was to disclose results of FCM, which were compared among IgG4-related ophthalmic disease (IgG4-ROD), idiopathic orbital inflammation (IOI), and extranodal marginal zone B-cell lymphoma (EMZL). MATERIALS AND METHODS: This is a retrospective observational study. Sixty-nine tumors comprising of 16 IgG4-ROD, 24 IOI, and 29 EMZL were enrolled in the study. All tumors, surgically excised, were diagnosed based on histopathology, immunoglobulin (Ig) heavy chain gene rearrangement, and FCM. In FCM, the percentage of T-cell markers (CD2, CD3, CD4, CD5, CD7, CD8), B-cell markers (CD10, CD19, CD20, CD23), NK cell marker (CD56) and cell surface kappa/lambda was searched based on medical records. Ig light chain restriction was evaluated from results in kappa/lambda deviation by FCM. RESULTS: The percentage of CD2, CD3, CD4, CD7, and CD10 was significantly higher in IgG4-ROD/IOI than EMZL (p<0.05 in every factor). In contrast, CD19 and CD20 percentages were significantly greater in EMZL than IgG4-ROD/IOI (p<0.01). There was no significant difference in any marker between IgG4-ROD and IOI. Kappa-positive cells were significantly greater in EMZL than IgG4-ROD/IOI (p<0.05). In kappa/lambda deviation, false-positive was noted in 3 (7.5%) benign IgG4-ROD/IOI and false-negative was observed in 10 (34.5%) EMZL cases. Sensitivity and specificity of Ig light chain restriction were 65.5 and 92.5%, respectively. CONCLUSION: Analyses of cell surface markers using FCM were useful in differentiating EMZL from IgG4-ROD/IOI. Sensitivity of Ig light chain restriction was relatively low in diagnosis of EMZL using FCM.
