Congenital Iris Ectropion
Congenital iris ectropion is more commonly called congenital ectropion uveae. It is a rare developmental eye condition present from birth in which the dark pigment layer from the back of the iris is ...

Congenital Cystic Eyeball
Congenital cystic eyeball, also called congenital cystic eye, is a very rare birth defect in which a cyst forms in the eye socket and the normal eyeball does not develop in the usual way. It happens ...
Congenital Anophthalmos with Cyst
Congenital anophthalmos with cyst is a very rare birth defect of eye development. In this condition, a child is born without a normally formed eye in the affected socket, and a cyst develops in the ...
Congenital Cystic Eye
Congenital cystic eye is a very rare birth condition. In this condition, a cyst-like sac grows in the eye socket where the eye should normally form. It happens very early in pregnancy, when the early ...
Cerulean Cataract
Cerulean cataract is a rare kind of childhood or developmental cataract. A cataract means the natural lens of the eye becomes cloudy instead of staying clear. In cerulean cataract, the cloudy spots ...
Congenital Blue Dot Cataract
Congenital blue dot cataract, also called cerulean cataract, is a type of childhood lens opacity in which many tiny bluish or whitish dots appear in the lens, often in both eyes. It is usually ...
Congenital Achiasma
Congenital achiasma is a very rare eye and brain problem that is present from birth. It happens when the optic chiasm, the “cross-road” where nerve fibers from the two eyes normally cross in the ...
Congenital Absence of Lacrimal Puncta and Salivary Glands
Congenital absence of lacrimal puncta and salivary glands means that a baby is born without the tiny tear drainage openings on the eyelids (lacrimal puncta) and without some or all of the main ...
Aplasia of the Lacrimal and Salivary Glands
Aplasia of the lacrimal and salivary glands means that the tear glands and saliva glands did not grow properly before birth. They are partly formed, very small, or completely missing. Because of ...
Cone-Rod Dystrophy Type 6
Cone-rod dystrophy type 6 (often written as CORD6) is a rare eye disease that slowly damages the light-sensing cells (cones and rods) in the retina, the thin “camera film” at the back of the eye. ...
Cone-Rod Dystrophy From ABCA4 Mutation
Cone-rod dystrophy from ABCA4 mutation is a rare, inherited eye disease that slowly damages the light-sensing cells (cones first, then rods) in the retina. The ABCA4 gene normally helps move used ...
Cone-Rod Retinal Dystrophy Caused by a CRX Mutation
Cone-rod retinal dystrophy caused by a CRX mutation is a rare inherited retinal disease. It happens when a disease-causing change in the CRX gene damages the work of the light-sensing cells in the ...
Cone-Rod Dystrophy Type 2
Cone-rod dystrophy type 2 is a genetic eye disease where cone cells (for central vision, color, fine detail) and later rod cells (for night and side vision) slowly die in the retina. People usually ...
PRPH2-Related Cone-Rod Dystrophy
PRPH2-related cone-rod dystrophy is a rare, inherited eye disease that damages the light-sensitive cells (cones and rods) in the retina because of harmful changes (mutations) in a gene called PRPH2. ...
Cone-Rod Retinal Dystrophy
Cone-rod retinal dystrophy is a rare genetic eye disease that slowly damages the light-sensing cells (cones first, then rods) in the retina, the thin layer at the back of the eye that receives light. ...
Cone-Rod Degeneration
Cone-rod degeneration (also called cone-rod dystrophy) is a rare, inherited eye disease that slowly damages the light-sensitive cells (photoreceptors) in the retina. First, the cone cells in the ...
Cone-Rod Dystrophy (CRD)
Cone-rod dystrophy (CRD) is a group of rare genetic eye diseases where cone cells (for central, color, and daytime vision) are damaged first and rod cells (for side and night vision) are damaged ...
X-Linked Incomplete Achromatopsia
X-linked incomplete achromatopsia is a rare inherited eye disorder present from birth. It mainly affects the cone cells in the retina, which are the cells that help us see color and see clearly in ...
Blue Mono-Cone Monochromatic Type Colorblindness
Blue mono-cone monochromatic type colorblindness is usually called blue cone monochromacy (BCM). It is a rare, inherited eye disease. In this condition, the red cones and green cones in the retina do ...
Blue Cone Monochromatism
Blue cone monochromatism, also called blue cone monochromacy, is a rare inherited eye disease present from birth. In this condition, the red-sensing cones and green-sensing cones in the retina do not ...
