Abstract

Millions of cataract surgeries with intraocular lens (IOL) implantation are performed worldwide. Although cataract surgery brings many benefits to the patients, the risk of various complications is still a concern. One of the infrequent adverse events but potentially affecting on patients’ visual acuity and contrast sensitivity is losing the transparency of IOL. IOL opacification may lead to IOL removal or exchange, which is unpleasant to both the patient and the surgeon. Several reports of acute IOL clouding are available in the literature describing various etiologies of this phenomenon, however, the exact mechanism remained unclear in some cases. Herein, we aimed to review the causes and outcomes of intraoperative and early postoperative IOL opacification.

Abstract

To describe the optical coherence tomography (OCT) findings of toxoplasmic retinochoroiditis at different stages of activity. Observational case series. A total of 32 eyes of 31 patients were included; 43 sets of OCT were reviewed. A total of 14 lesions were classified as active, 13 as partially active, and 16 as inactive. All active lesions demonstrated increased retinal thickness and reflectivity with blurring of details of retinal layers. Choroidal granuloma was detected in eight (61.5%) and serous retinal detachment in nine (64%). In partially active lesions, sustained thickening and/or attachment of posterior hyaloid face with fine epiretinal membrane was the hallmark. Scarified lesions showed decreased retinal and choroidal thickness starting from the periphery. Characteristic signs for decreased activity of a lesion seen in majority of both partially active and inactive lesions were RPE changes and retina-RPE approximation. We called this unique feature 'hourglass configuration'. Features in OCT are helpful to specify and monitor the activity of toxoplasmic retinochoroiditis. [ABSTRACT FROM AUTHOR]

Abstract

Fariba Ghassemi,1,2 Reza Mirshahi,1,2 Kaveh Fadakar,1,2 Siamak Sabour3 1Retina & Vitreous Service, 2Eye Research Center, Farabi Eye Hospital, Tehran University of Medical Sciences, 3Safety Promotion and Injury Prevention Research Centre, Department of Clinical Epidemiology, Shahid Beheshti University of Medical Sciences, Tehran, Iran Synopsis: In optical coherence tomography angiography, the choroidal vascular flow rate in choroidal melanoma is significantly lower than that in choroidal nevus.Objective: The objective of this study was to describe the choriocapillaris and retinal features imaged by optical coherence tomography angiography (OCTA) in eyes with choroidal nevus from small malignant choroidal melanoma.Methods: In this retrospective, noninvasive, observational study, 11 patients diagnosed with small choroidal mass (five with choroidal nevus and six with malignant melanoma) who underwent dilated fundus examination, ocular ultrasonography and OCTA images were compared.Results: In choroidal nevus of all patients, OCTA demonstrated a hyporeflective mass with no significant deformity of choroidal vasculature and an intact retinal pigment epithelium (RPE)–Bruch’s membrane complex. The flow void mass was surrounded by an intense vascular rim named as surface microvasculature (SMV) that had an approximately similar flow rate median of 63.68 mm2 (60.42–67.62 mm2), comparable with the median of the contralateral normal eye of 61.77 mm2 (60.42–64.53 mm2; P>0.09) for nevi. OCTA showed an obscured Bruch’s membrane–RPE–Bruch’s membrane complex and outer retinal layer in choroidal melanomas. Choriocapillaris flow rate over the melanomas was 55.73% (41.93%–60.82%), and the corresponding normal areas had a flow area of 62.75% (61.99%–63.10%; P=0.01). A flow rate difference between choroidal melanoma and nevus was significant (P=0.006). Axial and peripheral fee
