Type 3 macular neovascularization is characterized by a complex of pathological vessels located in the sensory retina. Fundus oculi examination reveals intraretinal hemorrhages, macular edema, hard exudates and pigment epithelial detachments. Indocyanine and fluorescein angiography, OCT and angio-OCT are used for diagnosis and treatment monitoring. The treatment efficacy depends on the disease severity and the therapy applied.

We present a 57-year-old referred reduced visual acuity who was in treatment with paclitaxel for developing metastatic breast adenocarcinoma. Ophthalmoscopic examination, optical coherence tomography, and autofluorescence show the cystoid macular edema, but fluorescein angiography is normal, without leakage of dye in the late times. The patient responds well 8 weeks after stopping antineoplastic. Paclitaxel can cause cystoid macular edema and lifting a recovery both anatomical and functional of the macula.

Diffuse Diabetic Macular Edema

INTRODUCTION: Diabetic retionopathy is a microangilpathy. The present study was done to investigate results of Intravitreal Triamcinolone Acetonide injection for the treatment diffuse diabetic macular edema. MATERIAL AND METHODS: The study included 40 eyes of 40 patients with clinically significant diffuse diabetic macular edema. Eyes were diagnosed with diabetic macular edema according to Early Treatment Diabetic Retinopathy Study guidelines. An Intravitreal injection of Triamcinolone Acetonide at the dose of 4 mg/0.2 ml was administered. Best corrected visual acuity was measured as the logarithm of the minimum angle of resolution (logMAR) and snellen vision drum and size of macular edema (hard exudates) was obtained by slit lamp biomicroscopy using +90 D Volk lens at each visit. Intraocular pressure (IOP) and other complications related with steroid and injection related complications were also evaluated. Subsequently patients were followed up on 1st day, 2nd week and 3rd month. RESULTS: All patients were completed second follow up at 3 months. The mean size of macular edema, which obtained at 3 months postoperatively, was significantly different from the baseline measurement from 1.4125 to 0.9474 DD. Mean visual acuity improved significantly from baseline at 3 months of follow up was 0.7421 LogMAR (≈ 6/30 in Snellen chart). Eleven eyes developed intraocular pressure higher than 21 mmHg at 2nd week postoperatively. Other drug and injection related complications were not developed. Increased IOP were controlled with anti glaucoma drugs. CONCLUSIONS: Intravitreal Triamcinolone was a promising therapeutic method for diabetic macular edema. TriamcinoloneAcetonide effectively reduces size of macular edema and improves visual acuity in the short term.Journal of Universal College of Medical Sciences (2015) Vol.03 No.02 Issue 10 Page: 30-34

Purpose: We describe the features of niacin maculopathy in a 61-year old man using ocular coherence tomography (OCT), fluorescein angiography, and electroretinography (ERG). Methods: A case report is presented. Results: A 61-year-old male presented with decreased visual acuity. Cirrus OCT revealed bilateral cystic macular edema, without leakage on fluorescein angiography. Dark-adapted maximal-flash ERG demonstrated an absent b-wave. Light-adapted flicker responses revealed diminished amplitude and delayed implicit time (IT). Multifocal ERG demonstrated diffusely decreased amplitudes. Two months after discontinuation of niacin, OCT demonstrated complete resolution of the macular edema. Dark-adapted maximal-flash ERG showed improvement in the b-wave. Light-adapted flicker responses improved in amplitude and decreased IT. Conclusions: To the best of the authors’ knowledge, this case is the first to demonstrate a reduced b-wave in niacin maculopathy. Discontinuation of niacin led to an improved b-wave response suggesting that niacin maculopathy is caused by niacin induced muller cell dysfunction.

We describe a 7-year-old girl who developed exudation nasally to the right optic disc due to retinal arteriovenous malformation. Fluorescein angiography, spectral domain optical coherence tomography, and optical coherence tomography angiography were performed. We give an overview of the different imaging techniques and discuss the differential diagnosis. Since there was no visual impairment, no treatment was started. A spontaneous decrease in edema and exudation was noted after 6 months.

Macular edema (ME) is a retinal condition in which central vision of a patient is affected. ME leads to accumulation of fluid in the surrounding macular region resulting in a swollen macula. Optical coherence tomography (OCT) and the fundus photography are the two widely used retinal examination techniques that can effectively detect ME. Many researchers have utilized retinal fundus and OCT imaging for detecting ME. However, to the best of our knowledge, no work is found in the literature that fuses the findings from both retinal imaging modalities for the effective and more reliable diagnosis of ME. In this paper, we proposed an automated framework for the classification of ME and healthy eyes using retinal fundus and OCT scans. The proposed framework is based on deep ensemble learning where the input fundus and OCT scans are recognized through the deep convolutional neural network (CNN) and are processed accordingly. The processed scans are further passed to the second layer of the deep CNN model, which extracts the required feature descriptors from both images. The extracted descriptors are then concatenated together and are passed to the supervised hybrid classifier made through the ensemble of the artificial neural networks, support vector machines and naïve Bayes. The proposed framework has been trained on 73,791 retinal scans and is validated on 5100 scans of publicly available Zhang dataset and Rabbani dataset. The proposed framework achieved the accuracy of 94.33% for diagnosing ME and healthy subjects and achieved the mean dice coefficient of 0.9019 ± 0.04 for accurately extracting the retinal fluids, 0.7069 ± 0.11 for accurately extracting hard exudates and 0.8203 ± 0.03 for accurately extracting retinal blood vessels against the clinical markings.
