Toward Efficient Identification of Retinal Diseases: A Lightweight Convolutional Neural Network‐Based Approach Using Optical Coherence Tomography

Healthcare Technology Letters, Volume 13, Issue 1, January/December 2026.
We propose a lightweight deep‐learning framework for efficient retinal disease diagnosis using optical coherence tomography images, combining lite convolution and global‐local fusion blocks for enhanced feature extraction. Achieving up to 99.70% accuracy on benchmark datasets with only 0.27M parameters, the model ensures high performance, low ...

Diagnostics of optic disk drusen in children

Oftalʹmologiâ, 2016
Diagnosis of deep optic disc drusen (OND) in children is difficult because they are not visualized ophthalmoscopically and often mimic a picture of stagnation, identifying the wrong tactics diagnostic and therapeutic actions.Materials and Methods ...

Apolipoprotein Localization in Isolated Drusen and Retinal Apolipoprotein Gene Expression

Investigative Opthalmology & Visual Science, 2006
To evaluate apolipoprotein (Apo) gene expression in native human retinal pigment epithelium (RPE) and neurosensory retina and to detect apolipoproteins within age-related, extramacular drusen.Drusen were isolated manually from 10 eyes of 10 donors (age range, 58-93 years) with grossly normal maculas that were preserved in 4% paraformaldehyde within 6 ...

Deep Learning‐Based Detection of Reticular Pseudodrusen in Age‐Related Macular Degeneration

Clinical &Experimental Ophthalmology, Volume 54, Issue 1, Page 78-85, January/February 2026.
ABSTRACT Background Reticular pseudodrusen (RPD) signify a critical phenotype driving vision loss in age‐related macular degeneration (AMD). This study sought to develop and externally test a deep learning (DL) model to detect RPD on optical coherence tomography (OCT) scans with expert‐level performance.

Optic Disc Abnormalities – Diagnosis, Evolution and Influence on Visual Acuity

Biomolecules & Biomedicine, 2010
Congenital abnormalities of the optic disc are not so rare. The etiology for the most of them is unknown. Visual acuity of affected eye may be minimally or severely affected, depending on the extent of lesion. All of these conditions can be unilateral or
