Metastatic Choroidal Melanoma Presenting as Neovascular Glaucoma
We present a case of a 20-year-old male who presented with 2 weeks of left eye redness and decreased vision who was found to have NVG. He was referred for evaluation of glaucoma. Fundoscopic and ultrasonographic examination revealed a mushroom-shaped choroidal mass with low internal reflectivity consistent with choroidal melanoma. The patient underwent enucleation, and metastatic workup revealed hepatic metastases. The patient died 18 months after initial diagnosis. This case emphasizes the importance of a complete ophthalmic evaluation in cases presenting with NVG of unclear etiology to exclude the presence of a potential...

Repairing Cyclodialysis by Riveting: A Flanged Polypropylene Suture
Cyclodialysis causes intraocular lens (IOL) pupillary capture. It requires surgical repair to prevent this risk of IOL pupillary capture. However, since repairing cyclodialysis is often technically difficult, other methods such as barricading by suturing, pupilloplasty, and pars plana fixation of the IOL were preferred. We applied a double-flanged (riveting) technique for repairing cyclodialysis to prevent IOL pupillary capture following intrascleral fixation of the IOL. Cyclodialysis was surgically repaired by riveting with double-flanged 6-0 polypropylene sutures in 3 cases with no recurrence of pupillary capture during ...

Surgery for Combined Hamartoma of the Retina and Retinal Pigment Epithelium
There is no consensus on whether and when surgical treatment is indicated for combined hamartoma of the retina and retinal pigment epithelium (CHRRPE). We aim to discuss the benefits of surgical intervention and techniques that may improve the outcome. A 24-year-old man experienced progressive visual loss for 6 months in his left eye due to CHRRPE. At presentation, visual acuity was 1.3 LogMAR and fundoscopy revealed extensive tractional pre- and epiretinal membranes, subretinal exudation, and a vasoproliferative tumor in the inferior periphery. A complete vitrectomy was performed, while paying special attention to vitreou...

Transscleral Removal of Subretinal Strand without Vitrectomy: A Case Report
Recurrence of inferior retinal detachment, after vitreoretinal surgery and silicone oil tamponade, along with a subretinal strand, presents a challenge for surgeons. Vitrectomy and retinotomy are the usual treatment in such cases. Here, we present a new transscleral method for addressing this problem. A 13-year-old boy with recurrent retinal detachment after silicone oil tamponade underwent scleral buckling surgery and had a transscleral subretinal strand removed without retinotomy. The retina reattached, and silicone oil was removed 3 months later. The best-corrected visual acuity was 0.4 in decimal vision at 1 year after...

Transient Angle Obstruction Detected by Anterior-Segment Optical Coherence Tomography and Intraocular Pressure Elevation after Hemodialysis
An 80-year-old Japanese man presented with decreased vision in his right eye (OD) after every hemodialysis (HD) session beginning several months previously. His local ophthalmologist prescribed antiglaucoma medications because of high intraocular pressure (IOP) (38 mm Hg) OD 4 months previously; with treatment, the IOP fluctuated between 6 and 34 mm Hg OD. When hospitalized, the IOP was measured, and the anterior chamber was observed by anterior-segment optical coherence tomography (AS-OCT) before and after HD. Before HD, the IOP levels were 7 mm Hg OD and 8 mm Hg in the left eye (OS). AS-OCT showed marked anterior iris bo...

Two Novel Disease-Causing Variants in the PDE6C Gene Underlying Achromatopsia
We report the clinical phenotype and genetic findings of two variants in PDE6C underlying achromatopsia (ACHM). Four patients with the variant c.1670G#x3e;A in exon 13 of the PDE6C gene were identified. Additionally, one had compound heterozygous genotype, with two variants in thePDE6C gene, a variant of c.2192G#x3e;A in exon 18 and c.1670G#x3e;A in exon 13. All patients presented the symptomatic triad of decreased visual acuity, severe photophobia, and colour vision disturbances. SD-OCT showed an absence of the ellipsoid zone, creating an optically empty cavity at the fovea in three patients. The patient with the compound...

Carotid Cavernous Sinus Fistula with Contralateral Feed Not Diagnosed by Virtual Assessment or by Non-Invasive Vascular Imaging
A 67-year-old woman had delayed initial diagnosis of her right low flow carotid cavernous fistula (CCF) during the coronavirus disease (COVID-19) pandemic due to difficulty detecting ocular signs via online virtual examinations. Her right eye conjunctival erythema and proptosis with medial rectus enlargement on computed tomography scan was initially misdiagnosed as euthyroid thyroid-associated orbitopathy without lid retraction. She developed vision loss, and increasing episcleral venous congestion and CCF was suspected. Computed tomographic angiography did not show an obvious fistula. Digital subtraction angiography revea...

Intraocular Endoscopy Resolved Tube Occlusion of an Ahmed Glaucoma Valve
We report a case in which intraocular endoscopy clarified the cause of Ahmed glaucoma valve (AGV) failure with a cloudy cornea. A 42-year-old patient with glaucoma underwent AGV implant surgery to treat secondary glaucoma due to chronic iridocyclitis in his left eye. After AGV, he developed bullous keratopathy (BK) in that eye. After Descemet stripping automated endothelial keratoplasty (DSAEK) was performed to treat BK, the intraocular pressure (IOP) increased and early failure of the DSAEK resulted again in a cloudy cornea. We could not precisely detect any cause of AGV failure with ordinary imaging instrumentation. An i...
