Meleha Ahmad, Edmund Tsui, R Theodore Smith
Choroidal osteoma (CO) is a rare, benign ossifying lesion of the choroid found in otherwise healthy patients. Although associated with good visual prognosis, tumor deossification in choroidal osteoma has been linked with vision loss, presumably due to overlying photoreceptor degeneration. Here the authors present a case of CO in an elderly male demonstrating tumor deossification and photoreceptor atrophy during a 3-year follow-up using enhanced depth imaging optical coherence tomography (EDI-OCT). Visual acuity was maintained due to the tumor's noncentral location...

A 12-year-old boy presented with a total rhegmatogenous retinal detachment and a giant retinal tear in the right eye. Clinical examination, optical coherence tomography, and fundus images showed an optically empty vitreous, lattice degeneration, and retinoschisis of the macula. Genetic testing revealed mutations in the COL2A1 and RS1 genes, confirming a dual diagnosis of Stickler syndrome and X-linked retinoschisis, respectively. This represents the first published account of a patient with both Stickler syndrome and X-linked retinoschisis...

The aim of this study is to report the coexistence of retinal arterial macroaneurysms (RAMs) and cerebral aneurysms (CAs) in a 58-year-old woman with hypertension. She was noted as having a 1-week history of vision loss in her left eye, along with a 2-month history of a nonspecific headache. Visual acuity was 20/32 in her left eye and 20/20 in her right eye. A fundus examination revealed multiple areas of retinal hemorrhages that were surrounded by circinate exudation in her left eye, as well as the generalized attenuation of the retinal arteries in both of her eyes...

A former 24-week-old premature infant was treated with intravitreal ranibizumab (Lucentis; Genentech, South San Francisco, CA) in one eye and conventional laser in the other eye for aggressive posterior retinopathy of prematurity in both eyes. Fluorescein angiography performed at 149 weeks of age showed persistent avascularity of the temporal peripheral retina in the ranibizumab-treated eye. This case report confirms the need for long-term follow-up of patients treated with ranibizumab monotherapy. [Ophthalmic Surg Lasers Imaging Retina...

Two women with unilateral vision loss from multiple evanescent white dot syndrome were imaged serially with swept-source optical coherence tomography (SS-OCT). En face wide-field structural images revealed peripapillary outer photoreceptor disruption better than conventional fundus autofluorescence imaging. OCT angiography (OCTA) imaging showed preservation of flow within the retinal vasculature and choriocapillaris. As OCTA imaging of the choriocapillaris continues to evolve, these images may lay the groundwork for future investigation...

BACKGROUND AND OBJECTIVES: Ophthalmology trainees commonly learn laser procedures on live patients. A simulator for learning peripheral iridotomy (PI), posterior capsulotomy, and retinopexy may improve patient outcomes. MATERIALS AND METHODS: A model eye with artificial tissues was designed. The tissues reacted to laser similarly to human tissues. Inexperienced (n = 6; first- to third-year residents) and experienced (n = 7; fourth- to fifth-year residents and staff) ophthalmic personal were compared on performance of the above laser procedures...

Yoshihiro Yonekawa, Cynthia X Qian, Avni V Patel, Leo A Kim, Dean Eliott
Intraocular foreign bodies (IOFBs) may be associated with occult exit wounds. The authors present a case of a man who sustained a zipper-tooth IOFB through the cornea from a car tire explosion. CT showed an IOFB within the vitreous cavity, but the IOFB was not identified during vitrectomy. Extension of the peritomy revealed an exit wound with the foreign body lodged in the extraocular space. This case demonstrates that IOFBs can rest within the vitreous cavity after creating an exit wound, but may escape detection by being driven back out of the globe during vitrectomy due to the pressurized eye...

Shintaro Nakao, Yoshihiro Kaizu, Yuji Oshima, Taiji Sakamoto, Tatsuro Ishibashi, Koh-Hei Sonoda
Punctate inner choroidopathy (PIC) is a relatively uncommon inflammatory multifocal chorioretinopathy that predominantly affects young, myopic women. Subfoveal choroidal neovascularization (CNV) often leads to rapid loss of sight. Fluorescein angiography (FA) and indocyanine green angiography (ICGA) remain the existing gold standards for CNV diagnosis. However, these methods are invasive and time-consuming. Recently, optical coherence tomography angiography (OCTA) has been used more frequently as an adjunct to FA/ICGA...

Thibaud Mathis, Laurent Kodjikian, Martine Mauget-Faÿsse, Audrey Feldman
The authors report, for the first time, an association between large colloid drusen (LCD) and choroidal neovascularization in a 58-year-old man. Multimodal imaging confirmed the diagnosis of LCD in both eyes and polypoidal choroidal vasculopathy in the left eye. The patient was treated with monthly intravitreal injections of aflibercept (Eylea; Regeneron, Tarrytown, NY). The authors hypothesize that these deposits are probably associated with retinal pigment epithelium dysfunction and could thus lead to delayed neovascularization and atrophy...

Severe anemia can cause multilayered retinal hemorrhages. A 65-year-old woman noted "red spheres" in the central vision of both eyes during a hospital admission for autoimmune hemolytic anemia. Examination revealed extensive multilayered retinal hemorrhages, including bilateral foveal preretinal hemorrhage. Spectral-domain optical coherence tomography localized the preretinal blood to the sub-internal limiting membrane (ILM) space. Various options are available for management of such hemorrhage, including observation for spontaneous resolution, YAG laser membranotomy, or pars plana vitrectomy with ILM peeling...

Molly W Orban, Luis J Haddock
MIRAgel (MIRA, Waltham, MA) scleral buckle material was initially developed in the 1980s as an alternative to more traditional silicone buckles. Long-term follow-up has demonstrated complications necessitating removal due to unanticipated hydrolytic degeneration of the exoplant. Material expansion and fragmentation have led to pain, limited extraocular motility, ocular masses, infection, and eventual extrusion. Complications occur later than in other materials; most patients need removal an average of 7 years to 13 years after implantation...
