Advancements in Myopic Macular Foveoschisis Research.

BACKGROUND: Presently, the global prevalence of myopia and high myopia reaches approximately 1.95 billion and 277 million individuals, respectively. Projections suggest that by 2050, the number of people with myopia may rise to 4.758 billion and those with high myopia to 938 million. In highly myopic eyes, the occurrence of MF is reported to be as high as 8-33%. SUMMARY: This review comprehensively addresses the classification, pathogenesis, natural progression, concomitant pathologies, and therapeutic strategies for macular foveoschisis in highly myopic patients. KEY MESSAGES: In recent years, macular foveoschisis has emerged as a prevalent complication in individuals with high myopia, primarily resulting from the combination of inward traction by vitreoretinal adhesions and outward traction exerted by posterior scleral staphyloma on the retina. While some maintain partial visual stability over an extended period, others may progress to macular holes or even retinal detachment. For highly myopic patients with macular foveoschisis, the mainstay procedures are vitrectomy, macular buckle, and posterior scleral reinforcement. However, there is controversy about whether to perform inner limiting membrane peeling and gas filling.

Intraoperative challenges and management of fibrovascular membrane with tractional retinoschisis in proliferative diabetic retinopathy.

BACKGROUND: In severe Proliferative Diabetic Retinopathy (PDR), fibrovascular membrane (FVM) causes macular tractional retinal detachment (MTRD) which threatens vision and eventually leads to blindness. Here we present a case of separation between the inner and outer retina in tractional retinoschisis, induced during intraoperative FVM delamination. CASE PRESENTATION: A 68-year-old woman presented with PDR in the right eye, characterized by a combined FVM and retinal detachment, for which a vitrectomy was performed. Multiple holes, large retinal detachment extending to all quadrants, and white-lined blood vessels with FVM were found during the procedure. When membrane delamination was performed, it strayed into the space between the inner and outer retinal layers without being noticed due to retinoschisis and multiple retinal holes. After removing the FVM and detaching the separated inner retina, fluid-gas and photocoagulation were performed. Retinal reattachment was successfully achieved after surgery, and the postoperative visual acuity was improved and maintained for 26 months postoperatively. CONCLUSIONS: When tractional retinoschisis due to FVM is combined with retinal holes in tractional retinal detachment (TRD), care must be taken to prevent delamination from straying into retinoschisis during separation.

[Analysis of the therapeutic efficacy of pars plana vitrectomy without intraocular tamponade in the treatment of high myopic eyes with myopic foveoschisis and central foveal detachment].

Objective: To investigate the efficacy of pars plana vitrectomy (PPV) without intraocular tamponade in the treatment of high myopic eyes with myopic foveoschisis (MF) accompanied by foveal detachment (FD). Methods: A retrospective case series study was conducted. The medical records of patients diagnosed with unilateral MF accompanied by FD at the Eye & ENT Hospital of Fudan University between May 2018 and December 2021 were collected. All patients underwent 23-gauge PPV with posterior vitreous cortex clearance, and no intraocular tamponade was applied. The cases were divided into groups based on whether the internal limiting membrane was peeled during surgery or retained. Follow-up was conducted for at least 12 months. The main outcome measures included postoperative best-corrected visual acuity (BCVA, converted to logarithm of the minimum angle of resolution), central foveal thickness (CFT), MF resolution, and complications. Statistical analyses were performed using t-tests, chi-square tests, Fisher's exact tests, and univariate and multivariate linear regression. Results: A total of 40 patients (40 eyes) with MF and FD were included in the study, with 30.0% being male and 70.0% female. The mean age was (56.9±11.7) years, and the axial length of the eyes was (29.1±1.9) mm. At 12 months postoperatively, BCVA improved from baseline 1.15±0.58 to 0.73±0.39 (t=6.11, P<0.001), and CFT decreased from baseline (610.1±207.2) µm to (155.9±104.1) µm (t=13.47, P<0.001). Complete resolution of MF with foveal reattachment was observed in 80.0% of eyes, with a median time of 6 (5, 8) months. There was no significant difference in BCVA and CFT between the internal limiting membrane peeled group and retained group [0.68±0.39 vs. 0.79±0.40, t=0.85, P=0.403; (148.3±63.8)vs.(164.3±137.2)um,t=0.48, P=0.634]. One eye experienced macular hole and another eye developed retinal detachment postoperatively. Correlation analysis showed a positive correlation between BCVA at 12 months postoperatively and baseline BCVA (ß=0.433, P<0.001). Conclusions: Pars plana vitrectomy without intraocular tamponade is effective in treating MF accompanied by FD. The choice between internal limiting membrane peeling and retention does not significantly affect visual prognosis.

The features of dome-shape Macula and related complications in high myopia on optical coherence tomography.

PURPOSE: This study used optical coherence tomography scanning and 3D reconstruction of the macular region in high myopia to examine more thoroughly and carefully the differences between high myopia-related macular complications with and without dome-shape macula (DSM) and to determine whether the DSM's fine structure has an effect on them. METHODS: Retrospective analysis of the medical records of 345 eyes with high myopia who underwent an optical coherence tomography (OCT) examination. They were divided into the DSM group (69 eyes) and the group without DSM (276 eyes). Macular complications between the two groups were compared. The height of the DSM and the diameter of the dome base were measured. And then the association between DSM type, protrusion height and macular problems were analyzed. RESULTS: Epiretinal membrane (ERM) and extrafoveal schisis occurred more frequently in the DSM group, but the was no statistically significant difference in the frequency of foveal schisis between the two groups. The majority of eyes in the DSM categorization had a horizontal oval-shaped domain. In the DSM group, there was no evident difference in the percentage of eyes with macular complications in the groups below 150 um and above 150 um. CONCLUSIONS: OCT examination-based fine macular structure analysis reveals that DSM affects various macular problems in distinct ways. DSM could increase the risk of extrafoveal schisis and ERM while decreasing the risk of foveal schisis. The height of the DSM had no obvious impact on the prevalence of macular complications.

Progressive retinoschisis and retinal detachment after uncomplicated macular hole repair surgery.

PURPOSE: To report a rare case of progressive retinoschisis and retinal detachment after uncomplicated macular hole (MH) surgery. CASE DESCRIPTION: A 67-year-old man with recent onset vision complaints in the right eye (visual acuity - 20/30), was diagnosed with a small idiopathic full-thickness MH. He underwent a 3-port 25G pars plana vitrectomy surgery with internal limiting membrane peeling and air endotamponade. RESULTS: MH closed with a normal foveal contour and intact retinal layers by the 1st post operative week and vision improved to 20/20. At the 7th week follow-up period, the patient complained of visual disturbances in his right eye for 2 days. Optical coherence tomography scans revealed development of peripheral retinoschisis which progressed towards the macula over the next 4 weeks. At the 13th week following the retinal surgery, patient developed sudden profound vision loss to hand motions and a total retinal detachment was noted. He underwent a second retinal surgery with retinectomy to the stiff retina and silicone oil endotamponade. At the last follow-up visit 8 weeks after the second surgery, the visual acuity had improved to 20/120 and the retina was well-attached with silicone oil in place. CONCLUSION: We present a rare case of progressive retinoschisis and retinal detachment caused by residual ILM contraction after MH repair surgery. To the best of our knowledge, no such complication after MH repair surgery has been reported in the literature.

Intraocular Pressure Lowering Associated With Worsening Optic Pit-Like Retinoschisis.

In this article, we present a case of optic pit-like macular retinoschisis in the absence of advanced glaucomatous cupping. Intraocular pressure (IOP)-lowering therapy, which was started due to an early concern for glaucoma, caused a worsening of the retinoschisis, which subsequently resolved on discontinuation of the IOP-lowering therapy. Lower IOP likely triggered intraretinal fluid accumulation by facilitating a translaminar gradient from the subarachnoid to intraretinal space.

Vitreomacular traction in diabetic retinopathy.

PURPOSE: Vitreomacular traction (VMT) has unique presentations in eyes with diabetic retinopathy (DR). This study aimed to investigate the characteristics and clinical course of VMT in DR. STUDY DESIGN: A retrospective case series. METHODS: Thirty eyes from 30 patients with DR and concurrent VMT were retrospectively enrolled. Baseline and final best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) characteristics were reported. Linear regression models were used to analyze the correlating factors for visual outcome. RESULTS: Of the 30 eyes, a thickened posterior hyaloid membrane was noted in all cases and multi-layered traction from different directions in 14 eyes (46.7%). Twenty-one eyes (70%) had tractional macular retinoschisis, seven (23.3%) had foveal detachment, five (16.7%) had a lamellar macular hole, and three (10%) had a full-thickness macular hole, including two with macular hole retinal detachment. Three eyes had spontaneous release of the VMT within 3 months of observation. For the remaining 27 eyes receiving operations, the VMT, full-thickness macular hole, and serous foveal detachment all resolved postoperatively with residual macular schisis in 6 eyes (22.2%) only. None of the baseline OCT characteristics were associated with postoperative BCVA (P > .05). CONCLUSIONS: VMT in DR had a thickened posterior hyaloid, and many of them had multi-layered traction and/or concurrent macular retinoschisis. Lamellar macular hole, full-thickness macular hole, or concurrent retinal detachment may also occur. Spontaneous resolution of VMT rarely occurred, and those who underwent operation for VMT had improved vision and macular structures with resolution of the macular hole and retinal detachment.

NEODYMIUM-DOPED YTTRIUM ALUMINUM GARNET LASER ABLATION OF INTERNAL LIMITING MEMBRANE TO TREAT MYOPIC MACULAR RETINOSCHISIS: CASE SERIES.

PURPOSE: To evaluate the efficacy and safety of neodymium-doped yttrium aluminum garnet laser ablation of the internal limiting membrane (ILM) to treat myopic macular retinoschisis. METHODS: Four patients with myopic myopic macular retinoschisis that extended out of the macular area were studied. All patients underwent yttrium aluminum garnet laser ablation of the detached ILM in the paramacular area, and the eyes were examined by ultra-widefield optical coherence tomography at the baseline and 6 months after the treatment. The measured outcomes were the foveal retinal thickness and the best-corrected visual acuity. RESULTS: Neodymium-doped yttrium aluminum garnet laser was applied to the paramacular ILM in all four eyes. In each eye, the procedure failed to disrupt the ILM, and no significant changes were observed in foveal retinal thickness or best-corrected visual acuity subsequently. No serious adverse event occurred in all eyes. A transient intraretinal hemorrhage developed at the site of the application in two eyes but resolved within a week after the treatment. CONCLUSION: Neodymium-doped yttrium aluminum garnet laser was applied to ILM in the peripheral macula in eyes with myopic macular retinoschisis. However, the lack of a reduction of the foveal thickness and improvement of the best-corrected visual acuity indicate that accurate focusing system is needed to treat eyes with myopic macular retinoschisis.

Retinal Detachments in Pediatric Patients With X-Linked Retinoschisis: Characteristics and Surgical Outcomes.

BACKGROUND AND OBJECTIVE: Retinal detachments (RDs) are a complication of X-linked retinoschisis (XLRS) with a poor prognosis. This study aims to report outcomes of XLRS-RD repair in pediatric patients. MATERIALS AND METHODS: The study is a retrospective analysis of pediatric patients undergoing vitreoretinal surgery for XLRS-RDs from 2000 to 2022. RESULTS: Nine patients (11 eyes) met inclusion criteria. All patients were boys, with a mean age of 8 years. Most RDs arose inferiorly (64%). Seven (64%) detachments were macula-involving. Seven (64%) detachments were repaired with combined scleral buckling and vitrectomy, two (18%) detachments were repaired with vitrectomy alone, one (9%) detachment underwent a primary scleral buckling procedure, and one (9%) asymptomatic detachment with a pigment demarcation line was observed. Silicone oil was used in eight of nine (89%) eyes undergoing vitrectomy. Final visual acuity was 20/200 or better in eight (73%) eyes. One eye that underwent surgical intervention remained unattached at follow-up. CONCLUSION: Surgical repair in patients with XLRSRDs was associated with successful reattachment, although visual prognosis varied. [Ophthalmic Surg Lasers Imaging Retina 2023;54:574-579.].

Concurrent Foveoschisis and Atrophy in a Patient With X-Linked Retinoschisis and Type 1 Diabetes Mellitus.

We report the case of a 28-year-old man with X-linked retinoschisis (XLRS) and type I diabetes mellitus. The patient had bilateral foveoschisis with a tractional retinal fold in the right eye. Optical coherence tomography (OCT) revealed hyperreflective material within the inner nuclear and outer plexiform layers, photoreceptor atrophy, and retinal pigment epithelium irregularities in both eyes. Fluorescein angiography showed hyperfluorescent foveal spots corresponding to the hyperreflective material observed on OCT. This is a unique presentation of XLRS, with concurrent foveoschisis and photoreceptor atrophy in both eyes. The hyperreflective material on OCT serves as a distinctive feature of XLRS.

AN EIGHT-YEAR RETROSPECTIVE STUDY OF THE ETIOLOGIES, CLINICAL CHARACTERISTICS, AND VISUAL OUTCOMES OF PEDIATRIC LAMELLAR MACULAR HOLE.

PURPOSE: To explore the etiologies, characteristics, and prognosis of lamellar macular hole (LMH) in pediatric patients. METHODS: A consecutive series of 59 patients (62 eyes) aged <16 years with MHs (lamellar and full-thickness) treated from 2013 to 2021 in a tertiary center was reviewed. Data collected included demographic and clinical characteristics, management, and outcomes of patients presenting with LMH. RESULTS: Twelve eyes (19.4%) of 11 children had LMH. Seven patients were male, with an average age of 6.9 years. The primary pathologies included X-linked retinoschisis in six eyes (50%); familial exudative vitreoretinopathy in two (16.7%); and ocular toxocariasis, Coats disease, persistent hyperplastic primary vitreous, and idiopathic LMH with associated lenticonus in one eye (8.3%) each. Four eyes (36.4%) showed tractional appearance and seven (63.6%) degenerative. All degenerative LMH showed ellipsoidal zone defect, significantly higher than that in the tractional group (25%, 1/4) ( P = 0.024). Five eyes achieved closed LMH and limited visual gain, four underwent surgery, and one closed spontaneously. CONCLUSION: X-linked retinoschisis was the most frequent primary cause in pediatric LMH. Two types of LMH can be classified: tractional and degenerative. The latter showed a higher rate of ellipsoidal zone defect. Vision improved after LMH closed, regardless of surgery or spontaneous closure.

EVALUATION OF PARAVASCULAR INNER RETINAL DEFECTS USING EN FACE OPTICAL COHERENCE TOMOGRAPHY.

PURPOSE: To evaluate the prevalence and risk factors for development of paravascular inner retinal defects (PIRDs) using en face optical coherence tomography. METHODS: This is a retrospective cross-sectional study. En face and cross-sectional optical coherence tomography images were reviewed (9 × 9 mm or 12 × 12 mm). Paravascular inner retinal defects were classified as either Grade 1 (i.e., paravascular inner retinal cysts) when the lesion was confined within the nerve fiber layer without any communication to the vitreous cavity or Grade 2 (i.e., paravascular lamellar hole) when the defects communicated to the vitreous. Paravascular inner retinal defect grading was correlated with presence of high myopia, stage of posterior vitreous detachment, and presence of epiretinal membrane and retinoschisis. RESULTS: Of 1,074 patients (2,148 eyes), PIRDs were detected in 261 eyes with a prevalence of 261 per 2,148 eyes (12.2%) and 176 per 1,074 patients (16.4%). A total of 116 eyes (44.4%) displayed Grade 2 PIRDs while 145 eyes (55.6%) were Grade 1. In the multivariate logistic regression model, the presence of partial/complete posterior vitreous detachment, retinoschisis, and epiretinal membrane was significantly correlated with PIRDs (OR = 2.78 [1.7-4.4], P < 0.001; OR = 2.93 [1.7-5], P < 0.001; and OR = 25.9 [2.8-242.5], P < 0.001, respectively). The presence of partial/complete posterior vitreous detachment and epiretinal membrane was also significantly associated with Grade 2 PIRDs versus Grade 1 PIRDs ( P = 0.03 and P < 0.001). CONCLUSION: Our results indicate that wide-field en face optical coherence tomography facilitates the identification of PIRDs over a large area of retina with a single capture. The presence of PIRDs was significantly associated with posterior vitreous detachment, epiretinal membrane, and retinoschisis, confirming the role of vitreoretinal traction in the pathogenesis of PIRDs.

LONG-TERM PROGRESSION PATTERN OF MYOPIC TRACTIONAL MACULOPATHY: Outcomes and Risk Factors.

PURPOSE: To evaluate the long-term progression pattern of myopic tractional maculopathy and the risk factors. METHODS: The prevalence and grade of myopic tractional maculopathy were assessed with optical coherence tomography at enrollment and at the 2-year follow-up. The severity of posterior staphyloma and the presence of dome-shaped macula were also evaluated. RESULTS: In total, 610 highly myopic eyes of 610 patients were analyzed. The prevalence of epiretinal membrane, myopic retinoschisis, and macular hole increased from 26.7%, 12.1%, and 4.4% at enrollment to 41.1%, 18.2%, and 9.5% at the 2-year follow-up, respectively. Epiretinal membrane progressed in 21.8% of eyes, but visual acuity did not decline significantly in these eyes. Myopic retinoschisis progressed in 6.8% of eyes, and macular hole progressed in 14.8% of eyes. Significantly greater best-corrected visual acuity reduction was detected in the eyes with myopic retinoschisis or macular hole progression than the rest ( P < 0.05). Multivariate analysis showed that longer axial length, more-severe posterior staphyloma, and absence of dome-shaped macula were associated with myopic tractional maculopathy progression. CONCLUSION: In highly myopic eyes, long-term visual acuity was relatively stable in those with epiretinal membrane, but was significantly affected by myopic retinoschisis or macular hole progression. Longer axial length, more-severe posterior staphyloma, and absence of dome-shaped macula were risk factors for myopic tractional maculopathy progression.

LONG-TERM EVOLUTION OF MYOPIC RETINOSCHISIS WITH A DOME-SHAPED MACULA AND PREDICTORS OF PROGRESSION AND VISUAL PROGNOSIS.

PURPOSE: To study the long-term natural course of myopic retinoschisis (MRS) with a dome-shaped macula (DSM) and to identify the factors affecting its development and visual prognosis. METHODS: In this retrospective case series study, we followed 25 MRS eyes with a DSM and 68 MRS eyes without a DSM for at least two years and observed changes in optical coherence tomography morphologic features and best-corrected visual acuity. RESULTS: During the mean follow-up of 48.3 ± 13.24 months, the difference in the rate of MRS progression between the DSM and non-DSM groups was not significant ( P = 0.7462). In the DSM group, the patients whose MRS progressed were older and had a higher refractive error than those whose MRS was stable or improved ( P = 0.0301 and 0.0166, respectively). The patients whose DSM was located in the central fovea had a significantly higher progression rate than those whose DSM was located in the parafovea ( P = 0.0421). For all DSM eyes, BCVA did not decrease significantly in eyes with extrafoveal retinoschisis ( P = 0.2500), patients whose best-corrected visual acuity decreased more than two lines had a greater central foveal thickness initially than those whose best-corrected visual acuity decreased less than two lines during the follow-up period ( P = 0.0478). CONCLUSION: A DSM did not delay the progression of MRS. The development of MRS in DSM eyes was associated with age, myopic degree, and DSM location. A higher schisis cavity predicted visual deterioration, and a DSM protected visual function in extrafoveal MRS eyes during the follow-up period.

Postoperative large intraretinal cavity and schisis with paravascular inner break in high myopia.

PURPOSE: To report distinct structural changes following surgery for myopic traction maculopathy (MTM). STUDY DESIGN: A single-center, retrospective case series. METHODS: Patients with MTM who underwent vitrectomy and had persistent large intraretinal cavities and schisis were reviewed. The pre- and postoperative clinical findings and optical coherence tomography characteristics are described. RESULTS: Five eyes of five patients were included in the study. Three patients had prominent schisis, and four had retinal/foveal detachment before surgery. All patients underwent fovea-sparing internal limiting membrane peeling during vitrectomy and had improved vision at 3 months after surgery. Large intraretinal cavities were noted on optical coherence tomography at the first postoperative exam in three patients and 12 to 18 months postoperation in the other two. The median height of the postoperative intraretinal cavities was 704 µm (range, 445-1287 µm). Inner retinal breaks were identified in all eyes, of which four were located in the paravascular area. The intraretinal cavity and schisis remained stable during the initial follow-up for an average of 35 months; later on, at > 5 years after the initial presentation two patients developed retinal detachment and one patient underwent vitrectomy with the retina reattached postoperatively. CONCLUSION: Large intraretinal cavities and schisis can be observed after MTM surgery, associated with paravascular inner breaks. The condition can progress after a long stable period; therefore, continuous follow-up is necessary.

PEELING AND INTERNAL LIMITING MEMBRANE REPOSITION (PAIR) FOR MYOPIC FOVEOSCHISIS.

PURPOSE: To report the outcomes of the Peeling and Internal Limiting Membrane Reposition (PAIR) technique in myopic foveoschisis. METHODS: A retrospective case series of eyes with myopic foveoschisis that underwent vitrectomy and PAIR. Visual acuity, fundus photographs, and optical coherence tomography measurements were obtained and analyzed. Data are presented as medians (ranges). RESULTS: A total of seven eyes underwent PAIR and were followed up for 339 days (188-436 days). No intraoperative complications were noted. One eye exhibited postoperative macular hole formation, but the hole was healed through fluid-gas exchange. At the last follow-up, the visual acuity had improved from 20/66 (20/332-20/40) to 20/40 (20/100-20/25), and the central foveal thickness had decreased from 576 µ m to 269 µ m. A repositioned internal limiting membrane (ILM) was observed in six of the eyes, and inner retinal dimples were noted in only two eyes. However, retinal wrinkles under the repositioned or perifoveal ILM were noted in five eyes. CONCLUSION: The PAIR technique relieved traction, restored the ILM, and achieved functional and morphological improvement in eyes with myopic foveoschisis. Limited occurrence of inner retinal dimples and retinal thinning was noted, but retinal wrinkles occurred, likely due to ILM contracture.

The development and evolution of lamellar macular hole in highly myopic eyes.

BACKGROUND/OBJECTIVES: To study the development, evolution, outcomes, and prognostic factors of lamellar macular hole (LMH) in highly myopic (HM) patients. METHODS: Fifty eyes from 47 HM patients with LMHs were retrospectively enrolled. Relevant pre- and post-LMH optical coherence tomography findings and visual acuity were collected. Structural progression was defined as an increase in the height of retinoschisis, and the development of foveal detachment, full-thickness macular hole, or retinal detachment. RESULTS: Four traction-related developmental processes were identified. Type 1 LMHs (8, 16%) developed from foveal avulsion caused by vitreomacular traction. Type 2 (32, 64%) and type 3 LMHs (5, 10%) formed from ruptured parafoveal and central foveal cysts, respectively. Progressive foveal thinning caused by epiretinal membranes (ERMs) without cystic changes led to type 4 LMHs (5, 10%). Retinoschisis developed before (9 eyes), after (10 eyes), or simultaneously with (6 eyes) the LMH formation. Structural progression was noted in 50%, 53%, 0%, 100% of patients with type 1-4 LMHs, respectively. Multivariable Cox proportional hazard model showed that greater residual foveal thickness (P = 0.001, adjusted odds ratio = 0.22, 95% confidence interval [CI], 0.08 ~ 0.56), and the absence of retinoschisis were protective against structural progression. Multivariable linear regression showed that poor baseline visual acuity (P < 0.001, ß = 0.74, 95% CI 0.41 ~ 1.07) and type 4 LMH predicted worse visual outcomes. CONCLUSIONS: Four traction-related LMH developmental processes were observed in HM eyes and exhibited different evolution and outcomes. LMHs with foveal thinning induced by ERMs had the worst outcomes.

Childhood Myopic Foveoschisis in LRPAP1-associated Myopia.

This case reports the development of foveoschisis in a child with high myopia due to a homozygous LRPAP1 pathogenic variant. A 9-year-old girl with high myopia due to a homozygous mutation in the LRPAP1 gene and a history of retinal detachment repair in her right eye, presented on follow-up with progressive myopic foveoschisis in the left eye noted on optical coherence tomography. The schitic changes evolved into a lamellar macular hole and required vitrectomy. Postoperatively, stabilization of the condition was achieved. Myopic foveoschisis could develop in childhood in the setting of recessive LRPAP1 pathogenic variants. Long_term follow-up is needed to determine the natural history of early-onset myopic foveoschisis.

[Gyrate atrophy of the choroid and retina with ornithinemia and foveoschisis (clinical observation)]. / Atrofiya girate khorioidei i setchatki s ornitinemiei i foveoshizisom (klinicheskoe nablyudenie).

Gyrate chorioretinal atrophy (GCA) is a rare hereditary disease with certain complications; one extremely rare complication of GCA is foveoschisis. For the first time in Russian ophthalmology, a 10-year-old female child has been described to have genetically verified GCA associated with the OAT gene in combination with ornithinemia and foveoschisis. The diagnosis was made on the basis of fundus examination, perimetry data, autofluorescence, optical coherence tomography, fluorescence angiography, electroretinography, mass spectrometry with confirmation by molecular genetic research. The presented clinical case illustrates the need for an interdisciplinary approach to the diagnosis of GCA with diagnostic algorithm involving various examination methods and doctors of different specialties.
