Neurotrophic Keratopathy

Neurotrophic keratopathy is a rare eye condition that is caused by damage to the trigeminal nerve, which is responsible for providing sensation to the cornea. This damage can lead to a decrease in corneal sensitivity and an impaired ability of the cornea to heal itself, resulting in a range of symptoms including pain, redness, and […]

Floppy eyelid syndrome

Floppy eyelid syndrome is a relatively rare eye condition that is characterized by the loss of the normal rigidity of the upper eyelid. This can cause the eyelid to easily flip inside out, leading to a variety of uncomfortable symptoms such as redness, itching, and tearing. The most common symptoms of floppy eyelid syndrome are […]

Crocodile shagreen:

Crocodile shagreen is a rare eye condition that affects the cornea, the clear outer layer of the eye. It is characterized by the appearance of raised, opaque, grayish-white or yellowish-white nodules on the surface of the cornea. These nodules resemble the rough, scaly skin of a crocodile, hence the name “crocodile shagreen.” The exact cause […]

Corneal guttatae

Corneal guttatae is a common eye condition that affects the cornea, which is the clear, dome-shaped tissue that covers the front of the eye. It is characterized by small, irregularly shaped bumps on the inner surface of the cornea that can affect vision and cause discomfort. While corneal guttatae is typically a benign condition, it […]

Congenital corectopia iridodialysis

Congenital corectopia iridodialysis is a rare eye condition that affects the iris and its attachment to the ciliary body. It is characterized by a displacement or abnormal positioning of the iris and a separation or detachment of the iris from its attachment to the ciliary body. The exact cause of congenital corectopia iridodialysis is unknown, […]

Cone cells

The human visual system is a remarkable and complex mechanism that enables us to perceive the world around us with astonishing detail and vividness. Central to this extraordinary ability is the presence of specialized photoreceptor cells known as cone cells. These cone cells, found in the retina of the eye, play a pivotal role in […]

Pthyriasis palpebratum:

Pthyriasis palpebratum is a medical condition that affects the eyelashes, leading to itching, inflammation, and redness of the eyelid margins. It is caused by infestation with the crab louse, which is a small, parasitic insect that feeds on human blood. Although this condition is relatively rare, it can cause significant discomfort and embarrassment for those […]

Ocular cysticercosis

Ocular cysticercosis is a parasitic infection that affects the eye. It occurs when the larvae of the pork tapeworm, Taenia solium, infest the eye tissues. It is a rare condition, but it can lead to vision loss if left untreated. Ocular cysticercosis is caused by the ingestion of contaminated food or water. The pork tapeworm […]

Ocular albinism:

Ocular albinism is a rare genetic disorder that affects the eyes and can lead to vision problems. It is caused by a mutation in the genes that are responsible for the production of melanin, the pigment that gives color to the skin, hair, and eyes. While ocular albinism can affect anyone, it is more common […]

Microspherophakia:

Microspherophakia is a rare genetic disorder that affects the lens of the eye. It is characterized by abnormally small and spherical lenses, which can cause various vision problems, including nearsightedness, astigmatism, and glaucoma. Microspherophakia is caused by a genetic mutation that affects the development of the lens during embryonic growth. The condition is inherited in […]
