Abstract
PURPOSE The report presents a modified surgical technique wherein the perfluorocarbon liquid (PFCL)-assisted drainage of subretinal fluid (SRF) through the choroid was combined with partial-thickness sclerectomy (PTS) and punch sclerostomy as a treatment for bullous central serous chorioretinopathy (bCSCR) in a nanophthalmic eye. METHODS The developed surgical approach is herein discussed together with a corresponding surgical video. Briefly, two 5 × 4 mm half-thickness sclerectomies and a punch sclerostomy (diameter: 2 mm) to the choroid were performed in the inferior quadrants. Following vitrectomy, SRF was drained through the exposed choroid in the region where the punch sclerostomy was performed, whereafter PFCL was instilled into the vitreous cavity. RESULTS The complete resolution of SRF accumulation was evident at one-week post-surgery, with no evidence of recurrence over an 18-month follow-up period. No abnormal fluorescent leakage or choroidal vasodilation were evident via fundus fluorescein angiography and indocyanine green angiography examination at the patient's final follow-up visit. CONCLUSION PFCL-assisted SRF drainage through the choroid combined with PTS and punch sclerostomy may represent a viable approach to treating patients with bCSCR and nanophthalmic eyes, providing a rapid and long-lasting means of eliminating SRF accumulation.

Abstract
Nanophthalmos is a rare congenital condition of the eyeball that is characterised by a smaller size of the anterior and posterior segments without associated ocular malformations. Typical features that have traditionally been described in these eyes are short axial length, thickened sclera, cornea with a smaller diameter, narrow anterior chamber, and an increased lens to globe volume ratio. However, at present, there is still a lack of recognised diagnostic criteria for nanophthalmos and a classification of its severity. Its clinical relevance stems from the increased risk of multiple ocular conditions, such as high hyperopia, amblyopia, angle-closure glaucoma, retinal detachment, and cataracts. Likewise, in relation to surgery in these eyes, there are particularities in cataract and glaucoma surgery and with a greater risk of associated intra- and postoperative complications. In this way, the treatment of nanophthalmos focuses on controlling the associated eye conditions and reducing and controlling surgical complications. This review aims to update what has been published in recent years regarding nanophthalmos.

Ophthalmic Genet 2023; 44:423-429. [PMID: 37501562 DOI: 10.1080/13816810.2023.2208220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Revised: 02/23/2023] [Accepted: 04/24/2023] [Indexed: 07/29/2023]
Abstract
BACKGROUND Nanophthalmos (NNO) is a rare condition with significantly shorter axial length than normal. Several genes are known to cause NNO, among them the MFRP and PRSS56 genes have been reported to cause majority of NNOs. The purpose of this study was to determine the genetic basis of Japanese patients with NNO. MATERIALS AND METHODS We studied seven patients with NNO. Whole exome sequencing (WES) and Sanger sequencing were performed to determine the variants causing the NNO. We also reviewed the medical charts of the patients to determine the phenotype of these seven patients. RESULTS WES revealed that four patients from three families carried homozygous frameshift variants of the PRSS56 gene (c.1066dupC). Two novel variants of the MFRP gene were detected in the other two patients: one proband had a homozygous missense variant (c.1486 G>A) and the other had a compound heterozygous variant (c.1486 G>A and c.662_663insT). The axial length of the eight eyes with the PRSS56 variant was 15.69 ± 0.48 mm (mean ± SD) and that for the 4 eyes with the MFRP variant was 15.63 ± 0.69 mm. Three of the six cases with the PRSS56 or MFRP variant had the uveal effusion syndrome. CONCLUSIONS NNOs in Japanese patients are caused by variants of the PRSS56 and MFRP genes as in other ethnic populations. In addition, two new variants of the MFRP gene were found in our cohort. The phenotypes and anomalies in Japanese patients with NNO were similar to those reported for other ethnic populations.

Abstract
INTRODUCTION Uveal effusion syndrome (UES) is a rare ocular disease causing idiopathic uveal effusion, often with associated ciliochoroidal and retinal detachment. UES diagnosis is challenging because of overlapping features with other ocular inflammatory, neoplastic, iatrogenic, and drug-induced causes of uveal effusion. While several successful surgical treatments have been described, such as full-thickness or partial-thickness sclerectomy, medical therapies may also have a therapeutic role. OBJECTIVE To provide an updated review of the published literature on the course of the disease, medical and surgical management strategies, as well as newer treatment modalities.

Abstract
INTRODUCTION Microphthalmos and nanophthalmos are uncommon ocular conditions, whereby affected eyes have smaller dimensions compared to the normal population. Microphthalmos and nanophthalmos present several challenges to ophthalmologists; they have spontaneous and post-operative sequelae such as high hyperopia, angle-closure glaucoma, uveal effusion syndrome, and retinal detachment. This systematic review and meta-analysis intends to assess the prevalence of both the spontaneous complications associated with nanophthalmos and microphthalmos, as well as the post-surgical complications associated with nanophthalmos or microphthalmos. METHODS AND ANALYSIS Articles will be searched for, on four online databases: PubMed, EMBASE, Scopus, and Web of Science. Two independent reviewers will identify the studies according to prespecified inclusion and exclusion criteria. All studies included with participants diagnosed with microphthalmos or nanophthalmos in one or both eyes, will be included if they have (i) more than 4 cases and (ii) defined microphthalmos/nanophthalmos as an axial length of < 21 mm or a high lens/eye volume ratio. Nanophthalmos may have an additional diagnostic criterion of posterior wall thickness greater than 1.7 mm. The prevalence of the following complications will be assessed: high hyperopia (spherical equivalent >3D), angle closure glaucoma, uveal effusion syndrome, retinal detachment, and chorioretinal folds. Studies that will be excluded are those that have not adequately defined the criteria for the diagnosis of nanophthalmos or microphthalmos, those studies that have less than five cases, studies with criteria not defined above, and deemed unsuitable, and studies in languages other than English with no published translation. Relevant data will be extracted and assessed for the risk of bias in each article using a modified Joanna Briggs Institute (JBI) assessment tool. The data will then be pooled to determine the prevalence of complications among patients with microphthalmos and nanophthalmos. If the data allows, subgroup analysis will be carried out according to axial length as well as subtype of microphthalmos/nanophthalmos (simple, complex, relative anterior, and posterior). DISCUSSION Although nanophthalmos is an uncommon condition that affects the eye, its management and complications can be sight-threatening. Thus, it is important to counsel patients and their families correctly (in the case of children) upon diagnosis and prior to any surgical intervention. This can only be done if the overall prevalence of complications is known. REGISTRATION PROSPERO CRD42021227847.

J Med Case Rep 2021; 15:515. [PMID: 34663453 PMCID: PMC8525029 DOI: 10.1186/s13256-021-03101-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Accepted: 09/08/2021] [Indexed: 12/01/2022] Open
Abstract
Background Uveal effusion syndrome is a rare disease characterized by exudative detachments of the choroid, ciliary body, and retina. Various surgical procedures and nonsurgical strategies have been described to treat uveal effusion syndrome with limited success. The treatment for uveal effusion syndrome remains a serious challenge for clinicians. To the best of our knowledge, no previous report has described a severe uveal effusion syndrome patient with nanophthalmos treated by using an anti-vascular endothelial growth factor agent alone. We report here one such case with unexpected positive results. Case presentation A 30-year-old Chinese male patient presented with painless vision loss in both eyes that had persisted for 2 months. Examination of the right eye revealed a best corrected visual acuity of 0.03; the best corrected visual acuity of the left eye was finger count/20 cm. The intraocular pressure was normal on both eyes. A-scan revealed an right eye axial length of 15.88 mm and a left eye axial length of 16.21 mm. In the right eye, half of the peripheral choroid and nearly three-fourths of the retina were detached. The left fundus was not visible because of the total retinal detachment located just behind the lens, which could be clearly observed directly with a slit lamp. Considering all the possibilities and available treatments as well as the patient’s intentions after discussion, we first administered an intravitreal injection of ranibizumab 0.5 ml into both eyes. The patient’s visual perception improved 3 days after the injection. One month later, most of the effusion under the choroid and retina was absorbed. Visual acuity improved from finger count to 0.05 in both eyes, and vision quality was remarkably improved. Encouraged by this good result, the patient opted to undergo a second injection 1 month later. Choroidal and retinal detachment completely vanished 30 days after the second injection. Conclusions Using an anti-vascular endothelial growth factor agent alone may be a potentially effective and safe method for managing some types of uveal effusion syndrome, such as in nanophthalmos. The injection may be administered before considering more aggressive procedures in some uveal effusion syndrome patients.
