Abstract
Purpose:To describe the visual outcomes and problems that resulted from surgical treatment of nanophthalmic complete retinal detachment (RD) with retina-lens contact. Methods: A multicenter retrospective case series with deep sclerectomy as a treatment was performed. Results: Five cases had extensive deep sclerectomies, 3 with intended drainage of subretinal fluid (SRF). The RD resolved 1 week postoperatively in 4 cases and within 1 month in 1 case. The visual acuity improved from light perception to a median of 20/100. Three cases had longstanding lens touch beyond 1 year and improved VA to 20/100, 20/150, and hand motions, respectively. Complications included focal lens dialysis in 2 cases (passive drainage of SRF) and lens or intraocular lens dislocation in 1 case each (active drainage of SRF). Ultrasound biomicroscopy and anterior optical coherence tomography showed a very narrow angle and short zonules. Conclusions: Deep sclerectomy results in good anatomic and functional improvements in advanced cases of nanophthalmos exudative detachment, which is often considered to be incurable.

Abstract
Introduction Nanophthalmos is characterized by a short axial length, a thick choroid, and a thick sclera. Unilateral symptomatic disc swelling in nanophthalmos presents both a diagnostic and a therapeutic challenge. Case Presentation A healthy 59-year-old man reported a two-week-long abrupt vision reduction in his right eye. 20/100 best spectacle (+17.25 diopter) corrected visual acuity, unilateral widespread disc enlargement, central scotoma, and a slight color vision disruption without an afferent pupillary defect were among the positive findings in the right eye. Workup for neuro-ophthalmology was negative. Numerous consultations did not suggest any form of treatment for the patient. Review of the optical coherence tomography (OCT) indicated a small, crowded optic nerve head and substantial diffuse choroidal thickening with dome-shaped temporal peripapillary area with choroidal expansion. In addition to circumferential anterior four-quadrant 95%-deep sclerectomy from recti insertion to the vortices, radial nasal posterior sclerotomy reaching the optic nerve sheath was performed on the patient. After the procedure, 2 weeks later, the patient's vision returned, and it persisted until the 6-month follow-up. By OCT, the two eyes were comparable as far as disc contour and nerve fiber layer thickness. Conclusion This form of sclerectomy, which aims at decompressing the oncotic choroidal pressure, is an effective treatment for compressive optic neuropathy in the context of nanophthalmos. Could sclerectomy assist in treating other optic neuropathies associated with peripapillary pachychoroid?

Abstract
Purpose In this study, we aimed to investigate clinical characteristics and histopathology and evaluate surgical outcomes of quadrantic lamellar-sclerectomy with sclerostomy for uveal effusion syndrome (UES). Design Retrospective, cohort study. Participants Overall, 106 eyes of 66 patients diagnosed with UES were treated at the Beijing Tongren Hospital between January 1, 2001 and June 26, 2021. Methods Patients were examined by routine ophthalmologic examinations, fluorescein and indocyanine green angiography (FFA/ICGA); axial length determination; color Doppler ultrasound (CDU); ultrasound biomicroscopy (UBM), optical coherence tomography (OCT), and optical coherence tomographic angiography (SD/SS-OCTA). Quadrantic lamellar-sclerectomy with sclerostomy was performed at the equator in all patients and histopathological examination of the excised sclera was analyzed in all samples. Main Outcome Measures The reattachment of the choroid and retina with resolution of the serous fluid, best corrected visual acuity (BCVA), choroidal thickness, and recurrence of ciliochoroidal detachment were the main outcome measures. Results Two subgroups were identified: (1) type 1 (nanophthalmic eye), wherein the eyeball was small (average axial length 15.83 ± 1.45 mm) with high hypermetropia (average 12.6 diopters) and (2) type 2 (non-nanophthalmic eye), wherein the eyeball size was normal (average axial length 23.45 ± 1.68 mm) with or without refractive error, combined with or without systemic symptoms. Histopathologically, types 1 and 2 demonstrated similarly abnormal sclera with the disorganization of collagen fiber bundles and deposits of proteoglycans in the matrix. Quadrantic lamellar-sclerectomy with sclerostomy was effective in both types 1 and 2, inducing post-operative resolution of the subretinal fluid accumulation and increasing the useful BCVA. The choroidal thickness was significantly different before and after surgery (P < 0.05). Approximately 98.1% of cases attained permanent reattachment within 6 months after one operation through this procedure. The single operation success rate was 96.2%, and success with one or two operations was 100%. Conclusions UES is caused by abnormalities of the sclera and increased resistance to transscleral fluid outflow, combined with increased choroidal thickness. Quadrantic lamellar-sclerectomy with sclerostomy is an effective treatment for UES that can rescue correct the useful visual acuity.

Abstract
The choriocapillaris is the innermost structure of the choroid that directly nourishes the retinal pigment epithelium and photoreceptors. This article provides an overview of its hemovasculogenesis development to achieve its final architecture as a lobular vasculature, and also summarizes the current histological and molecular knowledge about choriocapillaris and its dysfunction. After describing the existing state-of-the-art tools to image the choriocapillaris, we report the findings in the choriocapillaris encountered in the most frequent retinochoroidal diseases including vascular diseases, inflammatory diseases, myopia, pachychoroid disease spectrum disorders, and glaucoma. The final section focuses on the development of imaging technology to optimize visualization of the choriocapillaris as well as current treatments of retinochoroidal disorders that specifically target the choriocapillaris. We conclude the article with pertinent unanswered questions and future directions in research for the choriocapillaris.

Abstract
Aim To use OCTA to collect normative data describing the vascular perfusion of the macula and optic disc in adolescents. Methods This cross-sectional, school-based study was conducted from Oct 15, 2019, to Nov 30, 2019, in Tuyou County, Baotou, China. All eligible participants underwent a comprehensive questionnaire and ocular examination. The vascular perfusion of the macula and optic disc was determined using a spectral-domain OCTA device. Results A total of 570 anatomically normal eyes without a history of pathologic disease from 570 adolescents (mean ± SD age, 15.1 ± 1.9 years; 298 girls [52.3%]) were enrolled. In the macula, the mean ± SD perifoveal perfusion density (PD) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) was 44.2% ± 4.37% and 50.74% ± 3.98%, respectively. The mean ± SD foveal avascular zone (FAZ) was 0.32 mm2 ± 0.11 mm2. The mean ± SD peripapillary vessel density (PVD) was 54.98% ± 3.53%. The inferior hemiretinal SCP-PD, DCP-PD, FAZ, and PVD was larger in girls than boys (P = 0.006, P = 0.001, P < 0.001, and P = 0.006, respectively) Multiple regression analysis confirmed that sex independently affected the DCP-PD, FAZ, and PVD (P < 0.001, P < 0.001, and P = 0.029, respectively) and that axial length (AL) independently affected the FAZ area and PVD (P = 0.004 and P < 0.001, respectively). Conclusion Quantitative studies of the perifoveal vasculature in adolescents should consider the patient’s sex and AL. Our findings may provide useful information for the understanding and the management of retinal perfusion in Chinese adolescents.

Association between axial length and choroidal thickness in early age-related macular degeneration. PLoS One 2020; 15:e0240357. [PMID: 33035241 PMCID: PMC7546466 DOI: 10.1371/journal.pone.0240357] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Accepted: 09/24/2020] [Indexed: 11/19/2022] Open
Abstract
The clinical course of age-related macular degeneration (AMD) is related to choroidal conditions, and can be determined by the evaluation of the central choroidal thickness (CCT). The aim of this study was to determine the association between the axial length (AL) and choroidal thickness in AMD by measuring these parameters in patients with and without AMD. Seventy eyes of 70 patients (34 men and 36 women; age, 64-88 years; mean age, 77.0 ± 6.5 years) who underwent cataract surgery from February 2015 to March 2020 at the Department of Ophthalmology, Keio University School of Medicine were retrospectively analyzed. The AMD group (29 patients, 29 eyes) included eyes with early AMD, whereas the control group (41 patients, 41 eyes) included those without ocular diseases other than cataract. Optical coherence tomography images were used to measure the CCT and the choroidal vessel diameter (CVD). The IOL Master was used to measure the AL. The results revealed that mean CCT was greater in the AMD group (238.3 ± 108.3 μm) compared with the age-matched control group (187.2 ± 66.8 μm) (p = 0.03). The CCT was negatively correlated with AL in the overall sample (r = -0.42, p = 0.001), the AMD group (r = -0.42, p = 0.02), and the control group (r = -0.42, p = 0.006). Note that all eyes with CCT > 350 μm were included in the AMD group. CCT and CVD were positively correlated in the overall sample (r = 0.76, p < 0.001) as well as in the individual groups (AMD: r = 0.82, p < 0.001; control: r = 0.76, p = 0.004). Given that CCT is an important parameter for predicting the prognosis of subfoveal diseases, routine evaluation of AL may be valuable for a better understanding of the pathogenesis of AMD.

Abstract
Microphthalmos is a type of developmental disorder ophthalmopathy, which can occur isolated or combined with other ocular malformations and can occur secondary to a systemic syndrome. Nanophthalmos is one of the clinical phenotypes of microphthalmos. Due to the special and complex structure of nanophthalmic eyes, the disorder is often associated with many complications, including high hyperopia, angle-closure glaucoma, and uveal effusion syndrome. The management of these complications is challenging, and conventional therapeutic methods are often ineffective in treating them. The purpose of this paper was to review the concept of nanophthalmos and present the latest progress in the study of the pathogenesis and treatment of its complications. As it is considerably challenging for ophthalmologists to prevent or treat these nanophthalmos complications, timely diagnosis and a suitable clinical treatment plan are vital to ensure that nanophthalmos patients are treated and managed effectively.

Abstract
Purpose We report the case of an 11-year-old boy with posterior microphthalmos who exhibited normal and age appropriate development of visual acuity. Observations At the initial diagnosis, when he was 3 years old, the best-corrected visual acuity (BCVA) was 20/125 in the right eye (OD) and 20/200 in the left eye (OS) with high hyperopia (cycloplegic refraction +15.75 D sphere OD and +16.25 D sphere OS). Eight years after he began wearing hyperopic glasses, BCVA was 20/16 OD and 20/20 OS. Optical coherence tomography did not reveal a foveal pit in either eye throughout the observation period. However, elongation of the outer segment and widening of the outer nuclear layers were observed. Conclusion and Importance Many cases of posterior microphthalmos demonstrate subnormal BCVA due to an abnormal foveal structure (papillomacular retinal folds, absence of the foveal pit and avascular zone) and high hyperopia. However, if foveal maturity progresses, even if the foveal structure is abnormal, early aggressive amblyopia treatment can result in normal and age appropriate development of visual acuity.
