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

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

Eye coloboma is a condition present at birth where part of the eye does not fully form. It can affect the iris, retina, optic nerve, lens, or eyelid, and its impact on vision depends on which part of the eye is involved. Some people with coloboma see very well, while others may need glasses, specialty lenses, retinal monitoring, or support for reduced vision. A comprehensive eye exam helps determine whether the coloboma is mostly cosmetic, visually significant, or needs long-

Thyroid eye disease can cause dryness, bulging eyes, eyelid changes, and double vision. Learn what causes it, how it is treated, and when to seek urgent eye care.

Ocular myasthenia gravis affects the neuromuscular junction and can cause fluctuating ptosis, intermittent double vision, and variable eye muscle weakness. This clinical guide reviews in-office tests optometrists can use to evaluate suspected ocular MG.

Myasthenia gravis can cause droopy eyelids, double vision, blurred vision, and eye fatigue that often worsen throughout the day. Learn how this condition affects the eye muscles and when symptoms need medical attention.

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 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.

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.

A bright red spot on the white of your eye can look scary, but it is often caused by a subconjunctival hemorrhage. Learn why it happens, how long it takes to heal, and when it needs an eye exam.

Macular degeneration can cause blurry central vision, wavy lines, and difficulty reading. Learn how retinal imaging and OCT testing help detect and monitor macular changes early.

Slow adjustment to light and dark can sometimes be related to reduced blood flow to the retina or optic nerve. Learn why temporary dimming, graying, or loss of vision should be taken seriously and when carotid artery testing may be important.

Seeing feels instant, but your eyes and brain work together in a precise step-by-step process. Here is a simple guide to how light becomes vision.

Anterior uveitis, also called iritis, is inflammation inside the front part of the eye. It can cause eye pain, redness, blurry vision, and light sensitivity. Unlike mild irritation or pink eye, iritis often needs prescription treatment and close follow-up to prevent complications.

Facial fillers are popular cosmetic treatments, but rare vascular complications can affect vision. Here’s what patients should know about retinal vein occlusion, filler-related vascular risk, and urgent eye symptoms.

Super glue in the eye can cause the eyelids or lashes to stick together and may scratch the cornea. Do not force the eye open or use acetone. Eye doctors may use sterile ophthalmic ointment, warm compresses, and careful treatment to protect the eye.

Color vision deficiency is not always simple “color blindness.” Learn how clinicians test color vision, distinguish congenital from acquired defects, and recognize medication, retinal, optic nerve, and neurologic causes of color vision changes.

Learn how eye doctors read an HVF 24-2 visual field, including reliability, grayscale, total deviation, pattern deviation, MD, PSD, VFI, and common glaucoma patterns.
