Macular edema
Macular edema is a common fundus manifestation of various eye diseases, referring to the inflammatory reaction and fluid infiltration in the macula, the most light-sensitive part of the retina, leading to edema and severe vision loss. Symptoms of this disease include decreased vision and distorted vision.
View detailsSenile cataract
Senile cataract refers to the opacification of the lens that begins in middle-aged and elderly individuals. This condition is common in people over 60 years old. It is usually asymptomatic in the early stages, with painless, progressive vision loss occurring in later stages.
View detailsCorneal tumor
Corneal tumor is a relatively common tumor disease, mainly including conjunctival dermoid, intraepithelial carcinoma, and conjunctival squamous cell carcinoma. Once affected, it not only impacts the patient's appearance but also impairs vision and can even be life-threatening. Clinical analysis indicates that corneal tumors primarily occur in the inferotemporal limbus, but some corneal tumors can affect the entire cornea. Their surface is often covered by epithelium, with relatively clear boundaries, and fine hairs may be present.
Lacrimal gland tumor
Lacrimal gland tumors are tumors originating in the lacrimal gland, classified into benign and malignant types, with benign tumors accounting for 80%. Initially, the disease may present without obvious symptoms. As the tumor grows, clinical symptoms such as epiphora, globe displacement, and decreased vision may appear.
View detailsNystagmus
Nystagmus is a condition characterized by regular, rhythmic, and uncontrolled oscillations of the eyeballs, caused by changes in the proprioceptors of the eye muscles due to congenital factors or acquired diseases. Nystagmus can also occur in normal individuals when fixating on moving targets (such as striped rotating cylinders or striped clothing). The main symptoms include regular, rhythmic, and uncontrolled oscillations of the eyeballs. Other possible symptoms include the perception of stationary objects in the external environment as moving, decreased vision, and a persistent head tilt to one side.

Coats disease, also known as exudative retinitis, is a progressive eye disease characterized by retinal telangiectasia with varying degrees of intraretinal or subretinal exudation and exudative retinal detachment. This disease is mostly seen in male adolescents, less common in females, and can also occur in adults. It usually affects one eye, occasionally both. The course of the disease is slow and progressive. It is often unnoticed in the early stages until vision significantly declines, or leukocoria or strabismus due to disuse appears.
View detailsPediatric cataract
Pediatric cataract refers to congenital or developmental cataracts, which are common ophthalmic diseases in children and the leading cause of treatable blindness in children. The lens opacity in affected children is present at birth, and in some children, the lens opacity worsens with age, gradually affecting vision.
View detailsConjunctival tumor
Conjunctival tumors refer to abnormal cell proliferation originating from the conjunctiva, which can be divided into benign and malignant conjunctival tumors. Benign tumors mainly include conjunctival nevi, conjunctival papillomas, conjunctival dermolipomas, and conjunctival hemangiomas, most of which are congenital. Among malignant tumors, conjunctival squamous cell carcinoma is the most common.
View detailsTrachoma
Trachoma is a chronic infectious conjunctivitis and keratitis caused by Chlamydia trachomatis, affecting both eyes. It is a preventable blinding eye disease worldwide. This disease is common in children and adolescents. Symptoms in the acute phase include red eyes, photophobia, tearing, foreign body sensation, and mucous or mucopurulent discharge; in the chronic phase, there may be itching, foreign body sensation, dryness, and burning sensation, with a milder degree of discomfort.
