In the August 2023 edition of JAMA Ophthalmology, Patrice Hicks and colleagues published a study about social factors and corneal infections. The worse the vision when a patient comes in with a corneal infection and the later in the course of the infection that they come in, the worse the overall outcome will be. Dr.…

In the September 2023 edition of the journal Cornea, Lea Grauhan and colleagues published a case report of patients with ectrodactyly-ecotdermal dysplasia-cleft syndrome. What the heck is that? It is a rare genetic disease that causes limbal stem cell deficiency. That prevents the cornea from functioning normally. Even though it is very rare, it is…

In the August 2023 edition of the Journal of Cataract and Refractive Surgery, Dr. Tomas Bro and colleagues published a review about cataract surgeries in Sweden from 1992 to 2021. One of the measures they tracked was posterior capsule rupture rate. When a cataract surgery is done, the typical procedure involves placing a replacement lens…

In the July 2023 edition of JAMA Ophthalmology, William Paul and colleagues published a study that showed that an AI system could do an okay job of estimating vision from pictures of the eye. This was only done in the setting of diabetes, and the vision that it was estimating was best vision with the…

On our exams of the eye, we often see a findings that looks like small dots on the back part of the cornea. The cornea is the very front portion of the eyeball. These findings are called guttae, and they are indicative of decreased function of the back part of the cornea. The back part…

In the July 2023 edition of the Journal Cornea, Dr. Daniela Knauf and colleagues published a study about measuring intraocular pressure in keratoconus. Keratoconus is a commonly encountered disease in a cornea practice. In this disease, the cornea stretches out into a cone shape, and the thickness of the central cornea decreases. This thinning out…

In the July 2023 edition of the Journal of Cataract and Refractive Surgery, Bruno Boalento dos Santos and colleagues did a study that showed that OCT was an effective method for identifying macular diseases not detected clinically in cataract patients. What does that mean? Patients with cataracts have problems in the fronts of their eyes.…

One of the types of lenses that I put in after cataract surgery is a toric lens, which is an astigmatism-correcting lens. Astigmatism-correcting lenses only work if they are rotated into the correct position. Most lenses I put in are not toric, and they do not have to be rotated to exactly the correct places.…

In the June 2023 edition of the journal Ophthalmology, Rajvi Mehta and colleagues published a study about diet and glaucoma. Their study placed patients in two groups: low-fat diet or usual diet. The outcome measure they looked at was incidence of open angle glaucoma (the more common from of glaucoma compared to closed angle glaucoma).…

In the August 2023 edition of the journal Ophthlamology, Todd Margolis and Anat Galor authored an article about common myths in the field. The first myth that they describe has to do with Hutchinson’s sign in shingles. The bottom line is this: when there is a shingles rash over the upper face, eye involvement is…
