Clinical Diagnosis-Ophthalmology

OCT imaging yields better visualizationFuture increases in imaging speed will improve performance and functionality for OCT and OCT angiography (OCTA), said James Fujimoto, PhD.
Nystagmus diagnosis begins with thorough eye examA careful clinical workup, along with genetic testing, can help pinpoint what is behind congenital and infantile nystagmus.
POAG: Enigmatic group of heterogenous diseases?Various subtypes of primary open-angle glaucoma might exist. Continued research is needed to identify the characteristics of each subtype for better management.
Promising advances in uveal melanoma treatmentImmunotherapy and other investigational treatments appear to be promising for uveal melanoma, according to Carol Shields, MD.
Updated hand-held tonometer enhances clinical experienceA newly released hand-held tonometer model (Icare ic100, Icare U.S.A.) features several design upgrades while retaining the rebound technology for measuring IOP that was at the core of the earlier model.
Haze after PRK, LASIK tied to faulty epithelial regrowth
Haze after PRK, LASIK tied to faulty epithelial regrowthPoor regeneration of the epithelial basement accounts for most 'late haze' associated with PRK, LASIK, infections, or corneal transplants. Proper excimer laser maintenance may reduce irregularities.
The utility of normal tear osmolarity results
The utility of normal tear osmolarity resultsPatient symptoms are not an effective method to diagnose dry eye, as they often overlap with other pathologies. Tear osmolarity results provide clues for alternative diagnoses.
Handheld polarizing filter augments corneal imaging with simple approachUse of a handheld circular polarizing filter to intercept afferent and efferent light from a slit lamp or operating microscope highlights corneal structures that are otherwise invisible or barely seen.
Pearls for better diagnosis, treatment of red eyeOphthalmologists should consider various potential problems, including a number of systemic conditions and infections, when examining a rare or persistent red eye.
Why Acanthamoeba diagnosis is often challengingHaving an awareness of current best practices—such as epidemiology, risk factors, signs and symptoms, and tests—can be key to identifying and treating corneal infections.
