Safety and Effectiveness of Intravitreal Brolucizumab Injection in Combination With Sub-Tenon's Capsule Triamcinolone Acetonide Injection for Polypoidal Choroidal Vasculopathy During the Loading Phase.

BACKGROUND: This study evaluated the safety and effectiveness of combining intravitreal brolucizumab injection with sub-tenon's capsule triamcinolone acetonide injection (STTA) during the loading phase for polypoidal choroidal vasculopathy (PCV). METHODS: In this retrospective observational study, untreated patients with PCV receiving intravitreal brolucizumab injections with STTA during loading at Saitama Medical University Hospital's Eye Center from May 2021 to June 2022 were analyzed. Complete regression rates of polypoidal lesions were assessed using indocyanine green angiography 12 weeks post-treatment initiation. RESULTS: Nineteen patients (19 eyes) participated. Best-corrected visual acuity significantly improved at eight weeks compared to baseline. No significant intraocular pressure increases occurred throughout the loading phase, while central foveal and choroidal thickness significantly reduced at 4, 8, and 12 weeks. Subretinal fluid was present in all patients before treatment, rapidly resolving post-intravitreal brolucizumab injections and STTA, with residual rates of 36.8% (seven eyes) and 5.3% (one eye) at four and 12 weeks, respectively. Intraocular inflammation did not occur during the loading phase, and the complete regression rate of polypoidal lesions was 89.5% (17 eyes). CONCLUSIONS: Combining intravitreal brolucizumab injection with STTA during the loading phase may be one treatment option for PCV management.

Quantitative assessment of macular function after surgery for optic disc pit maculopathy: A case report.

RATIONALE: We describe a case of optic disc pit maculopathy (ODP-M) in which vitrectomy with juxtapapillary laser (JPL) treatment led to the reattachment of retinoschisis (RS) as well as serous retinal detachment (SRD). PATIENT CONCERNS: An 80-year-old man complained of distorted vision and decreased visual acuity (VA) in his left eye for 12 months. DIAGNOSIS: We conducted quantitative functional evaluation on the area of RS and SRD using the Humphrey visual field analyzer. Fundus examination and optical coherence tomography showed SRD and RS in connection with the optic disc. The best-corrected logarithm of the minimum angle of resolution (logMAR) VA was 0.7. INTERVENTIONS: The patient underwent JPL treatment combined with pars plana vitrectomy. During surgery, posterior vitreous detachment and tamponade were created with sulfur hexafluoride. OUTCOMES: After surgery, SRD (and subsequently RS) gradually reduced and had completely disappeared at 31 months. VA gradually improved and was 0.0 (logMAR) at 28 months. The analysis of the mean macular thickness of the central 3-mm diameter showed that the macula thickness recovered to 300 µm at 17 months postoperatively. Retinal sensitivity began to improve at 24 months postoperatively and had increased at 48 months postoperatively. LESSONS: In conclusion, vitrectomy with JPL treatment for ODP-M had a favorable anatomical outcome as well as a long-term functional outcome. These findings provide useful information for clinicians who are planning a therapeutic strategy, including the choice of surgical procedure for ODP-M.

Development and spontaneous closure of a secondary macular hole associated with submacular hemorrhage due to polypoidal choroidal vasculopathy: a case report.

BACKGROUND: Macular hole (MH) is a retinal break in the fovea involving partial or complete dehiscence of the neural retinal layers affecting the visual quality by decreasing visual acuity (VA) and visual deformation. We describe a case of secondary MH associated with submacular hemorrhage (SMH) due to polypoidal choroidal vasculopathy (PCV), which showed spontaneous closure. CASE PRESENTATION: A 67-year-old man developed decreased VA in his right eye due to an SMH. The VA was 20/50, and monthly intravitreal injection of aflibercept was administered three times. The SMH gradually decreased, and 10 months later the external limiting membrane was found to be perforated, resulting in MH. The old clot disappeared, and the MH remained for 10 months. Twenty-three months later, serous retinal detachment (SRD) involving the macula appeared and the MH had disappeared. SRD gradually disappeared, and macular configuration recovered. VA gradually improved and became 20/20 38 months later. CONCLUSION: Dynamic change of the ultrastructure in an unusual case of secondary-developed and spontaneously closed MH was clearly observed. Although the mechanism was unknown, the small diameter size and exudative PCV are thought to have contributed to the closure.

Macular Structure Recovery after Surgery for Optic Disc Pit Maculopathy.

The present report aimed to describe the macular structure's recovery process in a case of optic disc pit maculopathy (ODP-M) with outer layer hole following pars plana vitrectomy (PPV) with juxtapapillary laser treatment (JPL). We performed repeated optical coherence tomography (OCT) examinations to evaluate the macular structural changes. An 80-year-old man presented with distorted vision and decreased visual acuity (VA) in his left eye, experienced for 1 year, prior to presentation. Fundus examination and OCT showed intraretinal fluid (IRF) in the inner and outer retinal layers. Serous retinal detachment (SRD) with an outer layer hole in the macula was also evident. The IRF was connected to the optic disc; however, the SRD was isolated. Best-corrected VA was 20/100. PPV combined with JPL was performed. Posterior vitreous detachment creation and tamponade with sulfur hexafluoride was performed. Postoperatively, the inner retinal IRF at the fovea disappeared. The outer layer hole gradually closed and had completely disappeared 1 month postoperatively. After resolution of the outer layer hole, SRD reduced gradually and disappeared 8 months postoperatively, although the macular outer retinal IRF remained. The outer retinal IRF had partially resolved by the 18th postoperative month. Macular structure was completely recovered 31 months postoperatively, with an improved VA of 20/20. In conclusion, SRD might be associated with outer retinal IRF and outer layer holes. In cases of ODP-M, outer layer holes might induce optic disc-isolated SRD.
