1.Genetic diagnosis of 3 families with choroideremia.
Chinese Journal of Medical Genetics 2022;39(5):474-478
OBJECTIVE:
To analyze the clinical manifestations and causative gene variants of the choroideremia patients, and to help the patients bedifferential diagnosed by whole exome sequencing and provide theoretical basis for their genetic counseling.
METHODS:
Clinical data of 3 families were collected and genomic DNA was extracted respectively from peripheral blood of patients and related subjects. Exome targeted sequencing was used to screen suspicious gene mutations. Sanger sequencing and quantitative PCR were used to verify the candidate mutations and investigate the mutation carrying status of other members of the family. The candidate mutations were searched through HGMD and PubMed databases for the pathogenicity reports, and the pathogenicity of candidate mutations was judged according to a joint consensus recommendation of the American College of Medical Genetics and Genomics and the Association for Molecular Pathology.
RESULTS:
The proband of family 1 is c.1584_1587del (p.Val529Hisfs*6) variant hemizygote, whose daughter carries c.1584_1587del (p.Val529Hisfs*6) heterozygous variation. The proband of family 2 is a hemizygote with deletion of exons 10 to 15 (E10-15del), and her mother and sister carry the E10-15del heterozygous variation. In family 3, the proband is c.544delT (p.Cys182Valfs*14) variant hemizygote, and his mother is c.544delT (p.Cys182Valfs*14) heterozygote, but the father do not detect this variant. All the 3 families were detected pathogenic gene variations of CHM, two of which were known pathogenic variation and one of which was novel CHM gene c.544delT (p.C182Vfs*14) in this study. The c.544delT frameshift mutation of CHM gene can lead to the premature termination of the product protein translation and nonfunctioning protein. It is a pathogenic mutation according to ACMG guidelines.
CONCLUSION
The findings of this study expand the gene variation spectrum of choroideremia.

Choroid plexus tumors are uncommon brain tumors that primarily occur in children. Most of these tumors originate from the intraventricular area, and the most common clinicalpresentation is increased intracranial pressure. Dissemination through the cerebrospinal fluid space is the inevitable natural course of the disease. Here, we present 2 rare cases of adult choroid plexus carcinoma (CPC), each with distinct clinical presentation and progression. The first case was a 40-year-old male who presented with multiple intraventricular masses. After surgical biopsy, radiation and intrathecal chemotherapy failed to elicit any response. The patient progressed with spinal cord dissemination and expired 1 year later. The second case presented with visual disturbance, and brain MRI revealed a large ovoid juxtaventricular mass with peritumoral edema. This 49-year-old female patient underwent craniotomy for what was thought to be a high-grade glioma; however, the mass was connected to the choroid plexus at the operative field. Her pathology specimen was diagnosed as CPC, and adjuvant systemic chemotherapy was administered. She has now been free of recurrence for 10 months. The description of the presentation and progression of these rare adult-onset CPC provides insight for the diagnosis and treatment of other rare instances of choroid plexus tumors.

PURPOSE: To evaluate the long-term treatment outcomes of bevacizumab therapy in patients with myopic choroidal neovascularization (CNV). METHODS: A retrospective review was performed of medical records regarding 43 eyes with myopic CNV that were treated with intravitreal bevacizumab injection. Visual acuity at diagnosis was compared with that measured at the final follow-up; the incidence and timing of re-activation were evaluated. In addition, factors associated with final follow-up were analyzed. RESULTS: Mean patient age was 39.3 ± 12.9 years and mean spherical equivalent (SE) was −11.9 ± 4.4 diopters. Patients were followed-up at a mean of 42.1 ± 17.0 months. Re-activation of the lesion was noted in 17 eyes (39.5%). The mean time to first re-activation was 19.5 ± 15.4 months from the time that resolution of subretinal fluid/retinal fluid was confirmed after initial treatment. The mean visual acuity (the logarithm of the minimal angle of resolution) was 0.40 ± 0.25 at diagnosis and 0.26 ± 0.31 at the final follow-up. Visual acuity at the final follow-up was significantly improved when compared with the baseline value (p = 0.005). Patient age (p < 0.001), SE (p = 0.003), and visual acuity at diagnosis (p < 0.001) were significantly associated with visual acuity at the final follow-up. CONCLUSIONS: Bevacizumab therapy was a useful method for long-term treatment of myopic CNV. The observation of relatively late re-activation after the initial treatment suggests a need for continuous long-term follow-up.

PURPOSE: To evaluate the clinical presentations of focal choroidal excavation and to report long-term outcomes of cases without retinal disorders at the initial presentation. METHODS: A retrospective review of medical records was performed for patients diagnosed with focal choroidal excavation. Concomitant retinal disorders at the initial presentation were identified. In cases without retinal disorders, the development of retinal disorders during follow-up was also evaluated. RESULTS: Forty-five eyes in 45 patients were examined in this study. Focal choroidal excavation was accompanied with retinal disorders in 16 eyes (35.6%). In the remaining 29 eyes, only focal choroidal excavation was noted without any accompanying retinal disorders. The accompanying retinal disorders included choroidal neovascularization (n = 8), central serous chorioretinopathy (n = 4), epiretinal membrane (n = 1), macular hole (n = 1), branch retinal vein occlusion (n = 1), and uveitis (n = 1). Of the 29 eyes without retinal disorders, 22 were followed up for a mean period of 33.5 ± 18.2 months. Consequently, choroidal neovascularization was found to have developed in one eye at 59 months, and subretinal fluid had developed in two eyes at 17 and 28 months, respectively. CONCLUSIONS: Focal choroidal excavation was accompanied by retinal disorders in 35.6% of the included patients. In patients without retinal disorders, the development of a retinal disorder was noted in some eyes, suggesting the need for long-term regular follow-up in patients diagnosed with focal choroidal excavation.

PURPOSE: To report a case of choroidal neovascularization in a Best disease patient treated with intravitreal bevacizumab injection and followed up with optical coherence tomography angiography (OCTA). CASE SUMMARY: A 20-year-old female visited our clinic with decreased visual acuity of the left eye for 6 months. On optical coherence tomography (OCT), subretinal fluid and hyperreflective subretinal clumps were observed in the macula of the right eye. Subretinal hemorrhage and subretinal fluid were observed in the left eye. Choroidal neovascularization in the left eye was observed using OCTA, fluorescein angiography, and indocyanine green angiography. A full-field electroretinogram was normal in both eyes, but an electrooculogram revealed that the Arden ratio was 1.564 in the right eye and 1.081 in the left eye. Intravitreal bevacizumab injection was performed in the left eye. At 6 months after the intravitreal injection, the best-corrected visual acuity of the left eye had recovered to 20/20. OCT revealed that subretinal fluid reduced and choroidal neovascularization was stable. After 12 months, visual acuity of the left eye was maintained at 20/20, but OCTA revealed that choroidal neovascularization had increased. CONCLUSIONS: Choroidal neovascularization associated with Best disease can improve by intravitreal bevacizumab injection, and the changes in choroidal neovascularization can be followed using OCTA.

PURPOSE: To report a case of fulminant toxoplasmic chorioretinitis following intravitreal dexamethasone implantation monotherapy in a stabilized toxoplasmic chorioretinitis patient with initial treatment. CASE SUMMARY: A 60-year-old healthy female presented with decreased visual acuity in the left eye. On fundus examination, focal chorioretinitis and yellow-white infiltration were observed. Laboratory work-up, including blood chemistry, complete blood count, and serum serology, was negative; however, toxoplasmic chorioretinitis could not be ruled out. The primary lesion improved with antibiotics and prednisolone treatment. However, the patient did not come in for her follow-up visit, as she had already received an intravitreal dexamethasone implant for recurrent vitreous inflammation elsewhere. On her return, she presented with necrotic retinitis with extensive infiltration. She underwent diagnostic vitrectomy and implant removal. A diagnosis of toxoplasma antigen was confirmed by polymerase chain reaction analysis; the lesions stabilized after anti-toxoplasmic therapy. CONCLUSIONS: Intravitreal dexamethasone implant monotherapy with stabilized toxoplasmic chorioretinitis without systemic antibiotics can lead to fulminant toxoplasmic chorioretinitis and should be used with caution.

7.Choroidal Effusion after Consecutive General Anesthesia
Journal of the Korean Ophthalmological Society 2019;60(9):892-895
PURPOSE: To report a case of extensive choroidal effusion following the Valsalva maneuver under consecutive general anesthesia. CASE SUMMARY: A 41-year-old man who underwent panretinal photocoagulation with proliferative diabetic retinopathy had pars plana vitrectomy and endolaser photocoagulation under general anesthesia due to vitreous hemorrhage. Urology cooperated as the patient had hematuria; the day after the operation, he was transferred to the urology department. Two days after vitrectomy, the patient had an urgent transurethral bladder tumor resection under general anesthesia with suspicion of bladder tumor. At 6 days postoperatively, extensive choroidal effusion was observed from 8 to 10 o'clock on fundus examination and ultrasonography. On day 23 after urological surgery, the choroidal effusion had disappeared without treatment. CONCLUSIONS: Consecutive general anesthesia requires caution, as it is not only burdensome to the body as a whole but may also cause choroidal effusion in the eye.

PURPOSE: To report a rare case of Sjögren's reticular retinal dystrophy. CASE SUMMARY: A 54-year-old male presented with blurred vision and metamorphopsia in both eyes since a few years prior to his initial visit. There was a bilateral reticular network of yellow deposits throughout the posterior pole on fundus examination, which was hyperautofluorescent in fundus autofluorescence photographs. The pigment alterations were more visible with fluorescein angiography, which showed hypofluorescent lesions with hyperfluorescent borders. Spectral-domain optical coherence tomography showed elevations of the outer retina associated with the presence of subretinal hyperreflective material. Based on the conclusive correlation with clinical features, we diagnosed Sjögren's reticular retinal dystrophy. CONCLUSIONS: Sjögren's reticular retinal dystrophy is characterized by its specific pigment changes at the level of clinical manifestations and the retinal pigment epithelium. In cases of Sjögren's reticular retinal dystrophy, close monitoring is required because it has a lifetime risk of choroidal neovascularization.

PURPOSE: To investigate the short-term efficacy and safety of ranibizumab in the routine clinical setting in patients with neovascular age-related macular degeneration and to analyze the associated factors for visual outcome. METHODS: This was a post-hoc analysis of a ranibizumab regulatory post-marketing surveillance study in which 4,136 patients were enrolled and followed for 12 weeks. Change in best-corrected visual acuity (BCVA), size of choroidal neovascularization, and the presence of hemorrhage and exudate were analyzed and the association between BCVA change and baseline characteristics were investigated. Data on ocular and systemic adverse events were collected. RESULTS: Mean BCVA improved significantly and mean BCVA change was the logarithm of the minimal angle of resolution 0.13 ± 0.01 (p < 0.001). A lower baseline BCVA and younger age were significant predictive factors for visual improvement or maintenance (≥0 lines). For greater visual acuity gain (≥3 lines), no treatment history, lower baseline BCVA, younger age, and classic-type choroidal neovascularization were significant predictive factors. No new safety signals were found. CONCLUSIONS: In this study, conducted in real-world clinical practice with a large number of neovascular age-related macular degeneration patients, visual and anatomical outcomes improved significantly after three monthly ranibizumab treatments. Treatment-naive patients had a higher chance of greater visual gain (≥3 lines) than non-naive patients.

PURPOSE: To evaluate the influence of axial length on the recurrence of wet age-related macular degeneration (AMD) after anti-vascular endothelial growth factor therapy. METHODS: A retrospective review of the medical records for 45 eyes of 45 patients, who were diagnosed with neovascular AMD and treated with three ranibizumab injections per month, was performed. Axial length was compared between eyes with (recurrence group) and without (no recurrence group) recurrence of fluid during a 12-month follow-up period. In eyes with recurrence, the association between axial length and the time between the third injection and the first recurrence was also evaluated. RESULTS: The axial length was measured at a mean of 20.6 ± 10.1 months after the diagnosis of neovascular AMD. The mean axial length at that time was 23.33 ± 0.90 mm. The mean axial length was 23.29 ± 0.96 mm in the recurrence group (n = 30) and 23.40 ± 0.79 mm in the no-recurrence group (n = 15). There was no difference in the axial length between the two groups (p = 0.709). In the recurrence group, the period between the third injection and the first recurrence was not associated with axial length (p =0.582). CONCLUSIONS: There was no significant difference in axial length between eyes with and without recurrence after initial treatment for wet AMD. In addition, the time to first recurrence was not significantly associated with axial length. Because the present study was retrospective and the sample size was small, further prospective studies with a better design are needed to more accurately assess the influence of axial length.
