Clinicopathologic factors and survival in patients with sebaceous carcinoma of eyelid

This is a population-based analysis performed to evaluate the prognostic factors and survival of patients with sebaceous carcinoma of the eyelid. Patients with eyelid sebaceous carcinoma from 1973-2013 were identified from the Surveillance, Epidemiology and End Results (SEER) database and...

Congenital cranial dysinnervation disorders (CCDDs)

The term congenital cranial dysinnervation disorder (CCDD) was introduced by Gutowski et al. in 2003 to describe strabismus conditions that result from developmental error in innervation of some of the extraocular muscles. Examples of these conditions include Duane’s syndrome and...

A new observation point: updating the nomenclature and classification with OCT

The evolution of ophthalmic imaging technologies has been particularly rapid over the last few years. The author provides an update of the current terms for common signs and pathologies observed using optical coherence tomography. My experience as an ophthalmic technician,...

Essentials of OCT in Ocular Disease

Large language models in ophthalmology

Traditional artificial intelligence (AI) models typically require large amounts of labelled data for training. For example, to develop a model capable of detecting macular pathologies on optical coherence tomography scans, thousands of scans would need to be manually labelled by...
