Automated diagnosis of plus disease in retinopathy of prematurity using quantification of vessels characteristics

Scientific Reports
The condition known as Plus disease is distinguished by atypical alterations in the retinal vasculature of neonates born prematurely. It has been demonstrated that the diagnosis of Plus disease is subjective and qualitative in nature.

Selective Laser Sintering 3D Printing of Drug‐Loaded Intravitreal Implants

Advanced Functional Materials, EarlyView.
Selective laser sintering enables the fabrication of biodegradable and biocompatible intravitreal implants with tunable microstructures for sustained drug delivery. By modulating laser scanning speed, the polymer matrix architecture is engineered to control the release kinetics of dexamethasone and riboflavin over several months. This approach offers a

SmartPlus: a computer-based image analysis method to predict continuous-valued vascular abnormality index in Retinopathy of Prematurity

International Journal of Retina and Vitreous
Plus disease is characterized by abnormal changes in retinal vasculature of premature infants. Presence of Plus disease is an important criterion for identifying treatment-requiring cases in Retinopathy of Prematurity (ROP).

Grading diabetic retinopathy (DR) using the Scottish grading protocol

Community Eye Health Journal, 2016
Although traditionally the features of DR have been identified through direct ophthalmoscopy or slit lamp biomicroscopy, digital photography is more sensitive than direct ophthalmoscopy and is comparable to slit lamp examination by a trained observer.

Interleukin-1 Receptor Modulation Using β-Substituted α-Amino-γ-Lactam Peptides From Solid-Phase Synthesis and Diversification

Frontiers in Chemistry, 2020
As a key cytokine mediator of inflammation, interleukin-1β (IL-1β) binds to the IL-1 receptor (IL-1R) and activates various downstream signaling mediators, including NF-κB, which is required for immune vigilance and cellular protection.

Evolution of Ocular Organ‐On‐Chip Systems for Disease Modelling and Drug Testing: Where are We Now?

Advanced Therapeutics, EarlyView.
The rise in ophthalmic diseases due to aging, screen use, and environmental factors has driven demand for better ocular models. Traditional systems fall short, encouraging the development of organ‐on‐chip devices. These microfluidic platforms replicate eye tissue architecture, enable drug screening, and simulate ocular diseases.

Malarial retinopathy in adult: a case report

The Pan African Medical Journal, 2017
Although widely reported in children, the malarial retinopathy has rarely been described in adults. We observed a case in the department of ophthalmology at the pediatric and gynecology-obstetrics Yaoundé Hospital.
