“…In this research, we have used 430 images from six publicly available datasets such as; STARE 10 ,DRIVE 11 , DRIDB 12 , HEI-MED 13 , MESSIDOR 14 , and HRF 15 , in addition to one private dataset obtained from the Oak Ridge National Laboratory, USA (ORNL). The description and distribution of these datasets are described in the following two sections.…”

“…Recently, different techniques have been introduced including indocyanine angiography, optical coherence tomography (OCT), scanning laser ophthalmoscopy (SLO), and infrared imaging. Additionally, digital technology permits easy data processing and storage as well as worldwide images exchange [13]. Typically, ophthalmoscopy (fundoscopy) is used to determine the health of the retina and vitreous humor.…”

Diabetic retinopathy (DR) and age related macular degeneration (ARMD) are among the major causes of visual impairment worldwide. DR is mainly characterized by red spots, namely microaneurysms and bright lesions, specifically exudates whereas ARMD is mainly identified by tiny yellow or white deposits called drusen. Since exudates might be the only manifestation of the early diabetic retinopathy, there is an increase demand for automatic retinopathy diagnosis. Exudates and drusen may share similar appearances, thus discriminating between them is of interest to enhance screening performance. In this research, we investigative the role of bag of words approach in the automatic diagnosis of retinopathy diabetes. We proposed to use a single based and multiple based methods for the construction of the visual dictionary by combining the histogram of word occurrences from each dictionary and building a single histogram. The introduced approach is evaluated for automatic diagnosis of normal and abnormal color fundus images with bright lesions. This approach has been implemented on 430 fundus images, including six publicly available datasets, in addition to one local dataset. The mean accuracies reported are 97.2% and 99.77% for single based and multiple based dictionaries respectively.

Background: Acute posterior multifocal placoid pigment epitheliopathy (APMPPE)is a rare inflammatory disease, and the differential diagnostic assessment is essential for its adequate treatment. Purpose: To perform clinical analysis and differential diagnosis for a case of APMPPE. Material and Methods:We present a case of a 26-year-old woman with APMPPE. The patient underwent an eye examination which included visual acuity assessment, refractometry, tonometry, perimetry, biomicroscopy, direct and indirect ophthalmoscopy, optical coherence tomography (OCT), fundus photography, and fluorescein angiography (FA). Endonasal electrophoresis was conducted in a routine manner using azithromycin, a macrolide antibiotic. Results: OCT found numerous flat yellowish-white and grey-pink lesions in the posterior pole of the fundus at the level of the retinal pigment epithelium and choriocapillary layers. FA showed irregularly shaped non-fluorescent lesions, which began to exhibit faint fluorescence a few minutes after the dye injection. The differential diagnosis should include serpiginous choroiditis, Vogt-Koyanagi-Harada syndrome, geographical choroiditis, acute retinal pigment epitheliitis (Krill disease), and choroidal neoplasm. Conclusion: Acute posterior multifocal placoid pigment epitheliopathy is an acuteonset disease. If the disease is suspected, a thorough history is essential, and the differential diagnosis should be performed for early treatment and referral to an appropriate specialist. Patients with this disease should be followed since recurrences can occur.
