To report two cases of benign intraretinal tumors of the inner nuclear layer (INL) associated with congenital hypertrophy of the retinal pigment epithelium (CHRPE). Multimodal imaging of two cases, including fundus color and autofluorescence photography, structural and en face spectral-domain optical coherence tomography (SD-OCT), OCT-angiography, fluorescein and indocyanine green angiography. During a routine examination, intraretinal tumors of the INL associated with several CHRPE lesions were observed in one eye of two male patients, aged 27 and 32 years, respectively. Multimodal imaging showed white multifocal lobulated lesions with arching extensions, located in the INL, which allowed diagnosing benign lobular inner nuclear layer proliferation (BLIP). BLIP is a rare benign tumor located in the INL with a unique pattern and only 4 cases have been reported to date. The present two cases allowed confirming that BLIP is associated with CHRPE, suggesting a concomitant developmental anomaly of the RPE and the inner retina.

To describe the presentation and surgical management of a young boy initially thought to have familial exudative vitreoretinopathy who was ultimately diagnosed with an unusually aggressive form of X-linked retinoschisis that included rapidly progressive bullous retinoschisis and tractional macular fold. Retrospective case report A 19-month-old boy with straightening of major arcades, peripheral retinal ischemia, and in the left eye, a large macular fold was initially diagnosed as familial exudative vitreoretinopathy. During follow-up, he developed a rapidly progressive bullous retinoschisis in the left eye involving the inferior macula extending superiorly up to the macular fold. This revised the working diagnosis to X-linked retinoschisis, which was confirmed by genetic testing. Pars plana vitrectomy, inner flap retinectomy, unrolling of the macular fold and inner flap retinectomy, and C3F8 gas tamponade were performed. This resolved the macular fold. The patient showed good anatomical results without surgical complications up to 18 months of post-operative follow-up. X-linked retinoschisis can rarely present in young children with macular fold and peripheral ischemia, mimicking familial exudative vitreoretinopathy. Rapidly progressive bullous retinoschisis in this setting can be treated with pars plana vitrectomy, inner wall retinectomy, and removal of the vitreous traction to improve visual prognosis.
描述一名最初被认为患有家族性渗出性玻璃体视网膜病变的小男孩的表现和手术治疗情况，该男孩最终被诊断出患有一种异常侵袭性的X连锁视网膜裂孔症，包括快速进展的大泡性视网膜裂孔症和牵引性黄斑皱褶。 回顾性病例报告 一名 19 个月大的男孩，主要视网膜弧变直，周围视网膜缺血，左眼出现大片黄斑皱褶，最初被诊断为家族性渗出性玻璃体视网膜病变。在随访期间，他的左眼出现了快速进展的大泡性视网膜裂孔，累及黄斑下部，并向上延伸至黄斑皱褶。这将工作诊断改为 X 连锁视网膜裂孔症，并通过基因检测得到证实。患者接受了玻璃体旁切除术、内瓣网状切除术、黄斑皱褶展开和内瓣网状切除术以及 C3F8 气体填塞。这解决了黄斑皱褶问题。患者术后随访18个月，解剖效果良好，无手术并发症。 X连锁视网膜裂孔症极少出现在黄斑皱褶和周边缺血的幼童身上，与家族性渗出性玻璃体视网膜病变相似。在这种情况下，可通过平面玻璃体旁切除术、内壁网状切除术和玻璃体牵引去除术治疗快速进展的大疱性视网膜脱离，以改善视力预后。

To highlight the clinical and optical coherence tomography (OCT) features of subretinal fibrin glue and its resolution over time in patients who have undergone glue- assisted retinopexy for Rhegmatogenous Retinal Detachments (RRD). A report of 2 cases with subretinal migration of fibrin glue. Both the cases were assessed with clinical examination, serial fundus photos and serial OCT scans through the area of subretinal fibrin immediately after surgery, at 1 week, 2 weeks and at 6 weeks. In both the cases of intraoperative subretinal glue migration during glue-assisted vitrectomy for RRD repair, the subretinal glue had a characteristic appearance and course of evolution. On examination and color photography, the glue had an amorphous whitish appearance with wispy edges. This corresponded to subretinal hyperreflective material (SHRM) on OCT with a layered appearance. By two weeks after surgery, the subretinal glue demonstrated substantial regression on retinal examination and on OCT scans. At 6 weeks visit, the entire glue was noted to be resorbed along with an intact photoreceptor outer segments/Ellipsoid Zone layer In summary, this report describes the clinical and OCT appearance of subretinal migration of fibrin glue. Subretinal fibrin appears whitish on examination and corresponds to layered SHRM without shadowing on OCT. It appears to resorb spontaneously within weeks with apparent recovery of the overlying photoreceptors.
强调视网膜下纤维蛋白胶水的临床和光学相干断层扫描（OCT）特征，以及在接受胶水辅助视网膜整形术治疗风湿性视网膜脱离（RRD）的患者中随着时间推移纤维蛋白胶水的溶解情况。 报告两例视网膜下纤维蛋白胶移位病例。两例病例均在术后立即、1周、2周和6周通过视网膜下纤维蛋白区域的临床检查、连续眼底照片和连续OCT扫描进行评估。 在这两例胶水辅助玻璃体切除术修复 RRD 的术中视网膜下胶水移位病例中，视网膜下胶水的外观和演变过程均具有特征性。在检查和彩色照片中，胶水呈无定形的白色外观，边缘模糊不清。这与 OCT 上分层外观的视网膜下超反光材料（SHRM）相对应。术后两周，视网膜下胶水在视网膜检查和 OCT 扫描中显示出大量消退。总之，本报告描述了视网膜下纤维蛋白胶移位的临床和 OCT 外观。视网膜下纤维蛋白在检查时呈白色，在 OCT 上与分层的 SHRM 相对应，没有阴影。它似乎会在数周内自发吸收，上覆的光感受器也会明显恢复。

To report a technique for reconstruction of large, persistent, chronic, myopic macular holes using a combined human amniotic membrane graft and autologous retinal transplant (AMN-ART). Three patients with large, myopic macular holes that failed prior surgical attempts and underwent subretinal amniotic membrane graft with overlying autologous retinal transplant and short-term perfluorocarbon tamponade. Pre- and postoperative visual acuity (VA) and images were analyzed at 3, 6, and 9 months. All 3 myopic macular holes remained closed at 9 months with resolution of central scotoma. The first case, a 69-year-old female, presented with a persistent macular hole whose minimum linear diameter was 1085 μm. Her pre-op VA of 20/200 improved by 9 months to 20/100. Secondly, a 72-year-old male with history of recurrent retinal detachment repair with silicone oil and persistent macular hole of 1134 μm presented with pre-op VA of 20/200, which was unchanged at 9 months. Lastly, a 76-year-old female with a persistent macular hole of 935 μm with preop VA of 20/80 improved by 9 months post-op to 20/50. No complications were encountered related to the grafts. Combined AMN-ART may provide a surgical option for repair of refractory, large, chronic myopic macular holes with underlying atrophy.

To report a novel surgical technique for scleral fixation of Carlevale intraocular lens (IOL) without conjunctival dissection using Hoffman pockets. An 80-years-old female with IOL dislocation in her right eye required IOL exchange. After removing the dislocated IOL, a Carlevale IOL was implanted, securing the self-blocking harpoons within scleral pockets which were constructed using Hoffman technique. Surgical procedure was uneventful. During the next 3 months follow up, Carlevale IOL remained stable within the scleral pockets, and no signs of IOL dislocation or decentration were observed. Visual acuity significantly improved from 20/200 preoperatively up to 20/32 postoperatively due to corneal scaring from previous herpetic keratitis. No postoperative complications were recorded. Creating scleral pockets without conjunctival dissection using Hoffman pockets technique, represent a reliable and effective method for achieving both secure fixation and effective scleral covering of Carlevale IOL haptics. Absence of conjunctival opening, apart from patient postoperative comfort, reduces risk of postoperative complications, including conjunctival erosion and infection. The presented technique offers a promising alternative for Carlevale IOL scleral fixation.

To report an atypical chorioretinal manifestation concomitant with severe scleritis in a patient diagnosed with relapsing polychondritis. A 53-year-old male, with a six-month history of recurrent bilateral auricular cartilage inflammation was admitted to our hospital. Clinical and pathological examinations of the auricular cartilage led to the diagnosis of relapsing polychondritis. Ophthalmological examination revealed a localized elevation in the superonasal quadrant of the left fundus, where the scleritis was more severe than in other regions. B-mode ultrasonography revealed choroidal thickening and subretinal lesions in this area, along with a white retinal lesion identified during the fundus examination. Further investigation using optical coherence tomography (OCT) unveiled subretinal and retinal lesions in the same region, with dispersed cells into the vitreous cavity in a fountain-like pattern. After treatment with systemic corticosteroids and cyclophosphamide, there was an improvement in scleritis, conjunctivitis, and retinal vasculitis; however, the white retinal lesion progressed to retinal atrophy. Concurrently, a decrease in the number of vitreous cells emanating from the area of fountain-like leakage was noted. Retinal manifestations of relapsing polychondritis are underrepresented in the literature. This report presents a unique case of relapsing polychondritis with a localized retinal manifestation observed on OCT imaging, thereby broadening our understanding of the potential localized retinal presentations associated with this disease.

To report the “Single Port Technique” for perfluorocarbon liquid (PFCL)-silicone oil (SO) exchange for the management of giant retinal tear detachments (GRTD). The previously reported techniques of direct PFCL-SO exchange used 2 ports to achieve the influx and outflux of fluid. The term 'Single Port' refers to the use of only one port as the exclusive port for the inflow of SO and the outflow of fluid meniscus and PFCL, performed alternately. This technique is proposed, with illustrated instructions and a surgical video. The newly proposed “Single Port Technique” offers a straightforward step using a switch between active aspiration by the vitreous cutter and active silicone oil injection through a single port without the need for assistance. This method has been performed by the authors on 29 patients, including 22 GRTD patients and 7 patients with rhegmatogenous retinal detachment caused by dialysis, and it has demonstrated its simplicity and reliability for use with only standard vitrectomy tools and machine settings. The Single Port Technique for PFCL-SO exchange for the management of GRTD and rhegmatogenous retinal detachment caused by dialysis has been tried and tested, and it is a valuable tool that can be easily used by any vitreoretinal surgeon.

To report a case of spontaneous resolution of subfoveal perfluorocarbon liquid (sPFCL). Methods: A 72-year-old male presented with poor vision in the left eye for two months. Ophthalmic examination revealed a visual acuity of counting fingers at 40 cm, pseudophakia, and rhegmatogenous retinal detachment in the left eye. The patient underwent 23G pars plana vitrectomy associated with a scleral buckle and silicone oil. Postoperatively, a retained sPFCL bubble was observed on OCT image. Results: Postoperatively, the sPFCL bubbles disappeared spontaneously by a full-thickness macular hole. Four weeks after surgery, the macular hole was closed, and visual acuity improved with preservation of foveal depression. Conclusion: Because spontaneous resolution rarely occurs, retinal surgeons prefer early evacuation of sPFCL. Herein, we report a new case of spontaneously resolved sPFCL and discuss the mechanisms for its resolution reported in the literature.

To report a case of Down syndrome with myopic choroidal neovascularization (CNV) and the treatment outcome. Case report. Main outcome measures include refractive error, fundus examination, optical coherence tomography (OCT), OCT angiography (OCTA), fluorescein angiography (FA), anti-vascular endothelial growth factor (VEGF) injections. A 12-year-old boy with Down syndrome presented at a regular check-up with decreased visual acuity (VA) with macular degeneration in the left eye. The best-corrected VA was 0.6 in the right eye and 0.1 in the left eye, which decreased from 0.3 1 year ago. The refractive error (spherical equivalent) was -5.25 diopters (D) in the right eye and -8.00 D in the left eye. Detailed examinations were performed under general anesthesia. The fundus examination showed macular degeneration with retinal pigment epithelium (RPE) atrophy, pigmentary changes, and fibrous tissue in the left eye. OCT showed CNV at the macula with edema, and OCTA showed spreading CNV above the RPE at the macula in the left eye. FA showed hyperfluorescence in the early phase and late dye leakage from the CNV. Intravitreal ranibizumab injections were administered twice within 2 months, and he maintained a VA of 0.1 in the left eye. CNV and associated macular degeneration may occur in Down syndrome with high myopia possibly because of the abnormal choroidal structure. In children with Down syndrome, regular fundus examinations with OCT are important for early detection and treatment of CNV.
