Helpful eye care tips, vision education, and modern optometry insights from OPTISM in Tampa, FL.

Isolated mid-peripheral retinal hemorrhages are an important retinal clue to ocular ischemic syndrome and severe carotid artery disease. This clinician-focused review explains the characteristic fundus findings, how to differentiate OIS from retinal vein occlusions and diabetic retinopathy, and why prompt carotid evaluation can preserve vision and reduce stroke risk.

Retinitis pigmentosa is a genetically diverse group of rod-cone dystrophies that requires more than recognition of classic bone-spicule pigmentation. This clinical guide reviews OCT, fundus autofluorescence, visual fields, ERG, genetic testing, treatable complications, referral considerations, and practical follow-up for optometrists.

Photochromic lenses are a convenient lens upgrade that automatically darkens outdoors and clears indoors. They offer UV protection and comfort, but they may not fully replace polarized sunglasses, especially for driving.

Have FSA or HSA funds available? Learn how you may be able to use them for eye exams, prescription glasses, contact lenses, prescription sunglasses, and medical eye care.

Ehlers-Danlos syndrome affects connective tissue throughout the body, including parts of the eye. Here’s what patients should know about vision changes, dry eye, corneal problems, and warning signs.

Guillain-Barré syndrome is a rare nerve condition that can affect more than the arms and legs. In some patients, it can cause double vision, droopy eyelids, trouble moving the eyes, and dry eye from poor blinking. Here’s what patients should know about the eye-related warning signs.

Pituitary tumors are usually benign, but they can affect side vision when they press on the optic nerves. Learn the symptoms, how common they are, and why an eye exam can help detect early warning signs.

Horner’s syndrome can cause a smaller pupil, mild droopy eyelid, and sometimes a lighter-colored iris when present from birth. Learn how optometrists compare acquired Horner’s syndrome with congenital Horner’s syndrome, what red flags require urgent evaluation, and why pediatric cases need careful monitoring for vision development.

Adie’s tonic pupil is a condition where one pupil becomes larger and reacts slowly to light, often causing glare, light sensitivity, and near focusing problems. This guide explains how optometrists diagnose Adie’s pupil, rule out more serious causes of anisocoria, and manage symptoms with reading glasses, bifocals, tinted lenses, polarized sunglasses, and specialty contact lenses.

Eye freckles are usually harmless pigmented spots, but they should be monitored. Learn the difference between choroidal, conjunctival, and iris nevi, how doctors photograph them, and which warning signs need attention.

Ocular coloboma results from incomplete closure of the embryonic fissure, classically producing inferior or inferonasal defects involving the iris, lens zonules, chorioretina, optic nerve, or multiple ocular structures. Clinical evaluation should distinguish typical uveal coloboma from atypical coloboma-like lesions, assess macular and optic nerve involvement, document OCT findings, and monitor for complications such as amblyopia, choroidal neovascularization, and retinal det

Cataract surgery follow-up care is essential for safe healing and clear vision. Learn how optometrists co-manage cataract surgery and what is checked at each post-op visit.

Myopia, hyperopia, and astigmatism are often described simply as “nearsightedness,” “farsightedness,” and “blur,” but clinically they reflect different optical relationships between axial length, refractive power, accommodation, and corneal or lenticular curvature. This clinician-friendly review breaks down how each refractive error changes the focal point of light, why symptoms may vary between patients, and what optometrists should consider when prescribing lenses, evaluati

Doctors do not need to “sell” glasses in the exam room. They need to connect the patient’s prescription, symptoms, lifestyle, and eye health needs to a clear eyewear recommendation. Here’s how to recommend glasses, lens upgrades, and prescription sunglasses in a way that feels educational, ethical, and patient-centered.

A cataract is a clouding of the natural lens inside the eye. As the lens becomes harder, yellow, and cloudy, vision may become blurry or glary. Cataract surgery removes the cloudy lens material and replaces it with a clear implant.

Corneal cross-linking is a treatment used to strengthen the cornea and help slow or stop keratoconus progression. Learn how it works, who may need it, and why early monitoring is important.

Corneal topography and Pentacam tomography provide detailed information about corneal shape, elevation, and thickness. This clinician-friendly guide explains how to interpret each map, recognize patterns of keratoconus and other thinning disorders, evaluate progression, and avoid common diagnostic mistakes.

Keratoconus is an eye condition that affects the cornea, the clear front window of the eye. In a healthy eye, the cornea has a smooth, dome-like shape. With keratoconus, the cornea gradually becomes thinner and steeper, causing it to bulge forward into a cone-like shape. This change can distort how light enters the eye, leading to blurry, shadowed, or irregular vision. Keratoconus often starts in the teenage years or early adulthood, but it can be diagnosed at different ages.

Ocular HSV and herpes zoster ophthalmicus can both cause keratitis, uveitis, trabeculitis, and elevated IOP. This clinical guide reviews key exam findings, Hutchinson’s sign, oral antiviral treatment, and steroid use in inflammatory high-pressure cases.

Ocular herpes simplex and shingles around the eye can both cause redness, pain, light sensitivity, and vision changes. Learn how they differ and why early eye care matters.
