RESUMO

Vasoproliferative tumors (VPT) are benign retinal lesions that may cause epiretinal membrane proliferation and tractional retinal detachments (TRD). We describe a case of a 71-year-old woman who presented with a macula involving TRD in the setting of a VPT. Given the limited number of publications on the management of these cases, we aim to articulate some principles we believe may be helpful in planning a surgical approach that maximizes postoperative anatomic and functional outcomes. We hope that our video provides useful guidance in preparing the vitreoretinal surgeon for managing this uncommon entity. [Ophthalmic Surg Lasers Imaging Retina 2023;54:485-488.].

RESUMO

BACKGROUND/PURPOSE: To report an unusual appearance of severe bilateral serous detachments in a patient with Waldenstrom macroglobulinemia. METHODS: A case report of a Fifty-six-year-old female patient with Waldenstrom macroglobulinemia. RESULTS: A patient with Waldenstrom macroglobulinemia presented with serous retinal detachments at the time of diagnosis with Waldenstrom. The patient's IgM levels remained abnormally elevated in the initial stages of her disease course, leading to dramatic ocular findings and images on optical coherence tomography. Chemotherapy was initiated and IgM levels slowly declined, with some improvement in macular fluid as IgM normalized. CONCLUSION: Waldenstrom macroglobulinemia may lead to dramatic retinal pathology if IgM levels remain elevated. Prompt chemotherapy and reduction of immunoglobulin levels should be undertaken to preserve retinal architecture.

RESUMO

The authors report multimodal imaging including adaptive optics scanning laser ophthalmoscopy (AOSLO) (Apaeros retinal image system AOSLO prototype; Boston Micromachines Corporation, Boston, MA) in a case of previously diagnosed unilateral acute idiopathic maculopathy (UAIM) that demonstrated features of laser pointer maculopathy. The authors also show the adaptive optics images of a laser pointer maculopathy case previously reported. A 15-year-old girl was referred for the evaluation of a maculopathy suspected to be UAIM. The authors reviewed the patient's history and obtained fluorescein angiography, autofluorescence, optical coherence tomography, infrared reflectance, and AOSLO. The time course of disease and clinical examination did not fit with UAIM, but the linear pattern of lesions was suspicious for self-inflicted laser pointer injury. This was confirmed on subsequent questioning of the patient. The presence of linear lesions in the macula that are best highlighted with multimodal imaging techniques should alert the physician to the possibility of laser pointer injury. AOSLO further characterizes photoreceptor damage in this condition. [Ophthalmic Surg Lasers Imaging Retina. 2016;47:782-785.].

RESUMO

MEK inhibitor chemotherapy, used in various malignancies, has been reported to be associated with serous retinal detachments. This study reports serial multimodal imaging focused primarily on infrared reflectance and spectral-domain optical coherence tomography (SD-OCT) in the monitoring of MEK inhibitor retinal toxicity. The benefit of OCT angiography in understanding the pathophysiology of MEK inhibitor toxicity is also shown.

RESUMO

PURPOSE: To report two cases where the primary visual complaints were central visual phenomena, with normal fundus biomicroscopy. METHODS: History and clinical examination, fundus autofluorescence, and spectral domain-optical coherence tomography. RESULTS: The authors report 2 patients, a 66-year-old woman and a 77-year-old woman, who complained of a central visual disturbance in one eye. Best-corrected visual acuity was normal. Ophthalmoscopy in the first case was unremarkable and showed minimal retinal pigment epithelial mottling in Case 2. Spectral domain-optical coherence tomography revealed vitreomacular traction with foveal distortion in both eyes, associated with small cysts in the inner retinal layers and in one patient disruption of photoreceptors. CONCLUSION: Central visual phenomena are important clues for central vitreomacular traction, even in the presence of a normal fundus examination. The authors highlight the importance of performing spectral domain-optical coherence tomography evaluation in this setting before considering neurologic or systemic causes.

RESUMO

PURPOSE: To determine the changes in dry eye disease (DED) severity and the percentage of cells expressing HLA-DR on the ocular surface following treatment with lubricant eyedrops containing polyethylene glycol and propylene glycol (PEG/PG) and the gelling agent hydroxypropyl guar (HP-Guar). PATIENTS AND METHODS: Nineteen patients with DED used PEG/PG + HP-Guar eyedrops four times per day for 30 days. Assessments included DED severity (Ocular Surface Disease Index [OSDI], corneal staining, conjunctival staining, tear film break-up time [TFBUT], and Schirmer testing) and impression cytology of the conjunctiva with masked flow cytometry at baseline and at 30 days. RESULTS: There was a significant decrease in corneal staining (P<0.01), OSDI (P=0.02), and TFBUT (P<0.01) following treatment with PEG/PG + HP-Guar. Results from flow cytometry revealed a significant decrease in cells expressing HLA-DR (P=0.02). CONCLUSION: Treatment with PEG/PG + HP-Guar eyedrops showed improvement in dry eye severity and reduction in surface inflammation as indicated by a reduction in HLA-DR expression.

RESUMO

PURPOSE: To report a case of presumed gemcitabine-induced retinopathy and nephropathy. METHODS: Case Report. Retrospective chart review. RESULTS: A 64-year-old woman with a recent diagnosis of metastatic cholangiocarcinoma presented with progressive visual loss and renal failure shortly after the initiation of a chemotherapy regimen which included gemcitabine. Clinical examination and fluorescein angiography showed findings of severe retinal ischemia. CONCLUSION: Although gemcitabine chemotherapy has been reported to cause a Purtscher-like retinopathy, we propose in our patient a gemcitabine-induced vasculopathy that lead to significant retinal and renal ischemia.

RESUMO

IMPORTANCE: Our experience may be useful to other practitioners using compounded intravitreal agents, those suspecting infectious outbreaks, and those managing fungal endophthalmitis. OBJECTIVE: To describe a series of patients with fungal endophthalmitis following intravitreal injection of combined bevacizumab and triamcinolone acetonide prepared by the same compounding pharmacy. DESIGN AND SETTING: Noncomparative case series. PARTICIPANTS: Eight eyes of 8 patients who received an intravitreal injection of compounded combined bevacizumab-triamcinolone in a period of 3 weeks had subtle, nonspecific findings that were later diagnosed as fungal endophthalmitis. MAIN OUTCOME MEASURES: Visual acuity, response to antimicrobial therapy, and number of vitreoretinal surgical operations after diagnosis of fungal endophthalmitis. RESULTS: Eight patients developed endophthalmitis 41 to 97 days after receiving the intravitreal injection, which was prepared by the same compounding pharmacy. The injections occurred at the same location in New York. Treatment was based on clinical examination findings and knowledge of the etiology of the endophthalmitis. Eventually, all patients were treated with oral voriconazole. Five of 8 patients were initially treated with intravitreal antimicrobial agents. After 3 months of follow-up, visual acuities ranged from 20/50 to hand motions. Local, state, and federal health department officials were involved in investigating the source of the outbreak. CONCLUSIONS AND RELEVANCE: In the current study, we report a fungal endophthalmitis outbreak after intravitreal injection of contaminated, compounded combined bevacizumab-triamcinolone. In this series, Bipolaris hawaiiensis was the identified causative agent. The challenge of medical diagnosis, identification of the source of the outbreak, and management experience are highlighted in our series. Our experience may be useful to other practitioners using compounded intravitreal agents, those suspecting infectious outbreaks, and those managing fungal endophthalmitis.

RESUMO

PURPOSE: Descemet stripping automated endothelial keratoplasty (DSAEK) has its own set of complications including interface abnormalities. This case series presents the largest number of patients who developed textural interface opacity (TIO) at the graft-host interface after DSAEK. METHODS: This is a retrospective multicenter case series of 30 patients from 7 institutions with the finding of TIO. Clinical information collected included donor preparation details, recipient information, and surgical technique. Clinical outcomes included best-corrected visual acuity and status of TIO appearance at the last follow-up visit. Slit-lamp photographs were analyzed and compared. RESULTS: The majority of the patients (73%) had a best-corrected visual acuity of 20/40 or better. Four of the donor tissues were prepared with a microkeratome blade with the same lot number. Six patients had a central interface space between host and donor stromal surfaces--presumed interface fluid but potentially viscoelastic. A slight majority (57%) of patients had improvement in the severity of TIO, with 20% noted to have a complete resolution of TIO (mean follow-up of 11.9 months). Two clinical types of TIO were seen: an elongated type and a punctate type. CONCLUSIONS: Most patients with TIO after DSAEK obtain good visual outcomes. TIO spontaneously improves or even resolves during follow-up without intervention. The etiology of this condition is unknown, but we propose 2 different mechanisms. The elongated type could be secondary to an irregular cut of the donor with the microkeratome blade. The punctate type may be secondary to retained viscoelastic.
