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.

Pituitary tumors are common and usually benign, but macroadenomas can compress the optic chiasm and cause bitemporal visual field loss. This clinical guide reviews eye findings, testing, referral signs, and management considerations

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.

An altitudinal visual field defect means the top or bottom part of vision is missing. This pattern often respects the horizontal midline and may point toward disease in the eye, retina, or optic nerve. Brain-related visual field defects more often respect the vertical midline, making the pattern of vision loss an important diagnostic clue.

Altitudinal visual field defects often respect the horizontal meridian and commonly localize to the retina, retinal nerve fiber layer, or optic nerve. In contrast, chiasmal and retrochiasmal lesions often respect the vertical meridian. This clinical guide reviews localization, differential diagnosis, artifacts, and urgent red flags for doctors interpreting visual fields.
