Disease Glossary

H40.231-233 Intermittent Angle-Closure Glaucoma

Intermittent angle-closure indicates there is an obstruction to the aqueous outflow mechanism in the anterior chamber.

H35.711-713 Central Serous Retinopathy

A spontaneous serous detachment of the neurosensory retina in the macular region.

H35.52 Retinitis Pigmentosa

Retinitis pigmentosa is a group of genetic diseases that causes retinal degeneration and severe visual impairment.

H35.381-383 Toxic Maculopathy Of Retina

Medications like plaquenil and chloroquine can induce degenerative changes in the ganglion cells and photoreceptor cells of the retina.

H35.371-373 Macular Pucker

Macular pucker occurs when a contracting epiretinal membrane distorts the underlying retina.

H35.361-363 Drusen (Degenerative) Of Retina

Degenerative drusen also called familial or dominant drusen is an asymptomatic, bilateral, symmetric, yellow-white nodular thickening of the retinal pigment epithelium basement membrane.

H35.341-343 Macular Cyst Hole Or Pseudohole Of Retina

A macular hole is a defect of the foveal retina involving its full thickness from the internal limiting membrane (ILM) to the outer segment of the photoreceptor layer.

H35.32 Exudative Senile Macular Degeneration of Retina

Exudative senile macular degeneration or wet age-related macular degeneration is an aggressive condition that affects the macula region of the retina resulting in central vision loss.

H40.1211-1233 Low-Tension Glaucoma

Low-tension glaucoma (e.g., normal-tension glaucoma) is defined as glaucoma where the intraocular pressure is never measured above 21 mm Hg.

H35.31 Nonexudative Senile Macular Degeneration of Retina

Nonexudative senile macular degeneration or dry macular degeneration is a condition that affects the macula region of the retina resulting in central vision loss.
