Dual‐Branch Deep Neural Network for FLIM Parameter Estimation

Advanced Photonics Research, Volume 7, Issue 4, April 2026.
A dual‐branch deep network combining an autoencoder and a CNN is developed for fit‐free estimation in FLIM data. The proposed model was shown to outperform fit‐based method and single‐branch CNN model of the same complexity. Fluorescence lifetime imaging microscopy (FLIM) is a powerful tool for studying molecular interactions and cellular ...

Direct Ophthalmoscopy Toward the Retinal Periphery

Canadian Journal of Optometry, 1980
Direct ophthalmoscopic examina­tion toward the retinal periphery re­quires the use of increasing amounts of plus lens power in the instrument. The purpose of this clinical study was to determine the amount of ad­ditional plus power required to focus on peripheral fundus details.

Suprachoroidal and Subretinal Injections of AAV Using Transscleral Microneedles for Retinal Gene Delivery in Nonhuman Primates. [PDF]

, 2020
Retinal gene therapy using adeno-associated viruses (AAVs) is constrained by the mode of viral vector delivery. Intravitreal AAV injections are impeded by the internal limiting membrane barrier, while subretinal injections require invasive surgery and ...

Direct Ophthalmoscopic Indirect Ophthalmoscopy (DIDO) and Estimation Dynamic Distance Direct Ophthalmoscopy (E-DDDO). The Two Novel Uses of Direct Ophthalmoscope! [PDF]

Advances in Ophthalmology & Visual System, 2015
Aim: To describe two novel uses of a direct ophthalmoscope. 1) Direct ophthalmoscopic indirect ophthalmoscopy (DIDO) for the evaluation of the posterior pole of the eye from a distance using a direct ophthalmoscope and 2) estimation dynamic distance direct ophthalmoscopy (E-DDDO) for the objective measurement of accommodation in children.
