The rare neurocutaneous condition known as Sturge-Weber syndrome (SWS) is characterized by leptomeninges, or angiomas affecting the face, eyes, and brain. We report a newly diagnosed case that came to our institute complaining of a diminution of vision BE that had been going on for the past 1 year. Upon examination, the patient exhibited bluish discoloration of the sclera, an increase in the size of the cornea, and the characteristic port wine stain (PWS) on the face. Intraocular pressure BE was 30 mmHg with an applanation tonometer. The cup disc ratio on fundoscopy was 0.9 RE and 0.8 LE with characteristic glaucomatous disc changes BE. The child was treated with antiglaucoma medications. Abbreviations: SWS = Sturge-Weber syndrome, PWS = Port wine stain, CNS = Central nervous system, CT = Computed Tomography, IOP = Intraocular pressure, OCT = Optical coherence tomography, RE = Right eye, LE = Left eye, BE = Both eyes, ASOCT = Anterior segment optical coherence tomography.

A 36-year-old patient presented with a complaint of an extensive \"white scar\" in his right eye without pain after silicone oil presence in the vitreous cavity for 12 years. Slit-lamp microscopy revealed extensive corneal leukoplakia and mild limbus neovascularization. Anterior segment optical coherence tomography revealed marked eccentric thickening of the subepithelium and normal thickness of the stroma. We proceeded with silicone oil removal and intraocular and anterior chamber lavage at first, followed by epithelial lesion excision combined with amniotic membrane transplantation 3 months later. The patient was satisfied with the clear cornea appearance.

BACKGROUND: To discuss the efficacy of an inferior implant of XEN 63 gel stent in a patient with refractory glaucoma after trabeculectomy failure and vitreoretinal surgery with silicone oil tamponade.
METHODS: We report the case of a 73-year-old man with a history of refractory open glaucoma with trabeculectomy failure. He experienced recurrent retinal detachments with silicone oil tamponade, with uncontrolled intra-ocular pressure (IOP) after silicone oil removal. Due to the presence of oil emulsion in the anterior chamber, the chosen location for XEN 63 implantation was the infero-temporal quadrant. Mild hyphema and vitreous hemorrhage were seen post-operatively, but were self-limiting. At week 1, the intraocular pressure was 8 mmHg with a well-formed bleb seen in anterior segment optical coherence tomography (AS-OCT). At 6 month follow up, the patient maintained a IOP of 12 mmHg without topical hypotensive drugs. Slit lamp examination revealed a widespread, developed bleb with no signs of inflammation.
CONCLUSIONS: In this case of refractory glaucoma in a vitrectomized eye with previous oil tamponade, the inferior placement of the XEN 63 gel stent delivered an adequate intraocular pressure even at 6-months follow up, with a diffuse functional infero-nasal bleb seen with AS-OCT.

BACKGROUND: The aim of this study was to determine whether anterior scleral thickness (AST) varies significantly between patients with central serous chorioretinopathy (CSCR) versus normal individuals. To validate scleral thickness measurements by ultrasound biomicroscopy (UBM) vis a vis anterior segment optical coherence tomography (ASOCT).
METHODS: This case-control study analyzed 50 eyes of 50 patients with CSCR (cases) and compared it with that of 50 eyes of 50 age- and gender-matched controls. In cases, AST was measured at 1 mm and 2 mm temporal to the temporal scleral spur by ASOCT and UBM. In controls, AST was measured only by ASOCT. In all participants, posterior choroidal thickness (CT) was measured subfoveally, 1 mm nasal and 1 mm temporal to fovea by enhanced depth imaging optical coherence tomography.
RESULTS: The mean AST, as measured by ASOCT among cases and controls was 703.86 μm and 667.54 μm, respectively (P = 0.006). The mean AST by ASOCT and UBM in cases were 703.86 μm and 657.42 μm, respectively (P = 0.001). AST measurement by ASOCT and UBM showed a positive and statistically significant correlation (r = 0.431, P = 0.000). The mean CT among cases and controls was 443.56 μm and 373.88 μm, respectively (P = 0.000). We found a weak positive correlation (r = 0.11) in cases and weaker positive correlation in controls, between CT and AST measured by ASOCT.
CONCLUSIONS: Our findings suggest that AST varies significantly between patients with CSCR versus normal individuals. We found poor agreement of AST when measured by ASOCT and UBM.

UNASSIGNED: To report the clinical findings of unilateral central toxic keratopathy (CTK) associated with inadvertent exposure to topical minoxidil 5% solution 1 day after bilateral photorefractive keratectomy (PRK).
UNASSIGNED: Anterior segment slit-lamp photography, anterior segment optical coherence tomography (AS-OCT), pachymetry map, epithelial map, and manifest refractions were recorded.
UNASSIGNED: This is a case of a 27-year-old male who underwent bilateral PRK and presented 5 days after surgery with the complaint of acute decreased visual acuity in the left eye (LE). His LE was reportedly exposed to topical ethanol-based minoxidil 5% on postoperative day 1, which he was using as a posthair transplant treatment. Clinical examination showed hyperopic shift, poor visual acuity, central corneal opacity, epithelial irregularity, central corneal thinning, and flattening on AS-OCT. These findings were consistent with a diagnosis of CTK. The patient was monitored with conservative treatment and demonstrated full recovery after 6 months.
UNASSIGNED: It is recommended to warn patients who have undergone refractive surgery concerning the use of ethanol-containing agents, such as minoxidil solution, because of the possible risk of CTK, a complication not formally recognized.

BACKGROUND: We report a case and discuss the clinical characteristics and treatment of spontaneous Descemet membrane detachment (DMD).
METHODS: We describe a rare case of spontaneous DMD in a patient with prior anterior uveitis and provide a review of the current literature. A 20-year-old woman with a prior history of anterior uveitis presented with vision loss in the left eye. The slit-lamp examination showed corneal edema secondary to DMD, confirmed by anterior segment optical coherence tomography (AS-OCT). The patient underwent an intracameral injection of 20% sulphur hexafluoride (SF6) with complete resolution of the DMD. Although rare, several cases of spontaneous DMD have been reported in the literature, mostly occurring after intraocular surgery. We searched the Pubmed database (1949-2021) for peer-reviewed publications relevant to the topic of spontaneous DMD.
CONCLUSIONS: The pathogenesis of spontaneous DMD is complex and depends on several factors. It can occur due to anatomical anomalies, inflammatory disease, trauma, chemical injuries, and surgical or laser procedures. In most cases, early diagnosis and appropriate management led to resolution.

Nephrotic syndrome is a disease that causes fluid retention in the body due to loss of protein in the blood, which can lead to serous retinal detachment (SRD) in the macula. We report a case of severe SRD in both eyes and angle closure due to ciliary body edema caused by nephrotic syndrome. A 57-year-old man was admitted to the Department of Nephrology in our hospital for a thorough examination of his generalized edema. He was diagnosed with nephrotic syndrome but proved to be refractory to steroid treatment. Due to distortion symptoms in both eyes on the 30th day of hospitalization, the patient was referred to our department. Best-corrected visual acuity (BCVA) was 0.8 in the right eye and 1.0 in the left eye. Slit lamp examination and anterior segmental optical coherence tomography (OCT) showed shallow anterior chambers in both eyes. Fundus and macular OCT demonstrated severe SRD in the posterior pole of both eyes. After observing the presence of hypoalbuminemia, we considered the possibility of SRD and angle closure due to ciliary edema that resulted from the leaks associated with the nephrotic syndrome. Thereafter, ocular findings improved in conjunction with systemic symptom improvements associated with ultrafiltration and low-density lipoprotein apheresis. On the 60th day of hospitalization, his BCVA improved to 1.2 in both eyes, SRD disappeared, and the anterior chamber depth normalized. This case demonstrates the importance of recognizing SRD and angle closure associated with ciliary body edema as complications linked with nephrotic syndrome.

UNASSIGNED: To report a case of a bilateral complex uveitic glaucoma (UG) with pupillary block, rupture of the anterior lens capsule, and malignant glaucoma in a young high-myopic patient and to report anterior segment optical coherence tomography (AS-OCT) findings initially and following surgery.
UNASSIGNED: A 21-year-old high-myopic woman who had a history of anterior uveitis with extensive posterior synechiae, presented with acute bilateral ocular pain, redness, and blurred vision following bilateral Nd: YAG laser peripheral iridotomy (LPI).
UNASSIGNED: Visual acuity was limited to light perception in both eyes (OU), with a flat anterior chamber (AC) and anterior luxation of lens fragments. Intraocular pressure (IOP) was over 60 mmHg OU. AS-OCT showed closed angles and hyperreflective heterogeneous material within the flat AC. The iris and lens fragments were plated against the corneal endothelium OU. We performed an urgent pars plana vitrectomy associated with lensectomy. It was uneventful in OU. Repeated AS-OCT revealed a deep AC, widely open angles, and aphakia. IOP was lowered to 9 mmHg and visual acuity improved to 5/10 in OU.
UNASSIGNED: Performing LPI might be harmful in the presence of UG with extensive posterior synechia, resulting in complex mechanism glaucoma with aqueous misdirection syndrome associated with a pupillary block due to anterior lens luxation, even in high-myopic eyes. Nd: YAG LPI should not be performed simultaneously in OU, especially in pathologic eyes, to prevent bilateral vision-threatening complications. AS-OCT was of great help, allowing easy and detailed ultrastructural assessment of the ACs, and iridocorneal angles before and after surgery.

OBJECTIVE: This study reports a case of the spontaneous avulsion of primary pterygium with anterior segment optical coherence tomography (AS-OCT) findings.
METHODS: A 72-year-old woman complained of acute pain of the left eye. Primary pterygia were noted in both eyes on the initial examination 4 months ago. Slit-lamp microscopy revealed a nasal corneal epithelial defect, and the rolled elevated lesion in the corneal limbus of the left eye. She was diagnosed with a spontaneous avulsion of the corneal pterygium head. Then the avulsed pterygium head slowly recurred. The pterygium head of the fellow eye had a yellow-whitish elevated lesion beneath the epithelium with poor vascularity. AS-OCT revealed hyper-reflective foci beneath the epithelium corresponding to the yellow-whitish elevated lesion.
CONCLUSIONS: The present case revealed the spontaneous avulsion of the pterygium head leading to the corneal epithelial defects and ocular pain, while the pterygium head of the fellow eye showed subepithelial hyper-reflective foci suspicious of spheroidal degeneration on AS-OCT. In this case, the cause of spontaneous avulsion of the pterygium head might be potentially weak adhesion to the cornea due to spheroidal degeneration.
CONCLUSIONS: This case is a primary pterygium leading to spontaneous avulsion, in which hyper-reflective foci were noted in OCT.

OBJECTIVE: To report anterior chamber flare using laser flare photometry and ciliochoroidal detachment using anterior segment optical coherence tomography (AS-OCT) in a new onset acute lupus choroidopathy case.
METHODS: A 57-year-old woman with severe nephritis, pleural effusion, and ascites was referred to our ophthalmology clinic for rapid onset of bilateral blurred vision and eyelid swelling. She had a bilateral high-flared, shallow anterior chamber, and bilateral ciliochoroidal detachment, which was revealed using laser flare photometry and AS-OCT. She also had a serous retinal detachment and disc-macular retinoschisis with a thicker choroid and waved Bruch\'s membrane. Indocyanine green angiography (ICGA) demonstrated partial hypocyanescence in the early phase and multiple hypercyanescent spots at the intermediate to late phase, which are typical of lupus choroidopathy. Systemic lupus erythematosus was diagnosed, and after the administration of pulse methylprednisolone and pulse cyclophosphamide therapies, all eye findings completely resolved in a month, and all other signs and symptoms improved.
CONCLUSIONS: Lupus choroidopathy, which is less common than retinopathy, might be under-diagnosed because of its difficult evaluation. Although ICGA is the gold standard for diagnosing lupus choroidopathy, a high flare of the anterior chamber and ciliochoroidal detachment might be different from lupus retinopathy. Laser flare photometry and AS-OCT can be non-invasive, helpful tools for the longitudinal evaluation of the patient\'s response to therapy.
