About me
Li Zhendong, male, graduated from Chengde Medical College, engaged in this profession for over 30 years, deputy chief physician, discipline leader, member of the Ophthalmology Association of the Medical Association, has participated in numerous domestic and provincial ophthalmology academic conferences. Also involved in teaching at the hospital.
He is conscientious and responsible in his ophthalmic work, pays attention to improving his professional qualities and abilities, keeps up to date with new developments in international and domestic ophthalmology, has a solid foundation of theoretical knowledge, is familiar with ophthalmic diagnostic, treatment, and surgical methods, specializing in ophthalmic microsurgery, especially cataract and eye trauma.
In clinical practice, he is bold yet meticulous, good at critical thinking and innovation. In recent years, he has introduced and performed cataract removal surgery with implantation of artificial lenses, restoring sight to many patients. He has accumulated rich clinical experience in the diagnosis and treatment of pediatric refractive errors, eye trauma, and coal mine eye injuries, showing unique skills in surgical treatment.
He has published over 20 papers in international, domestic, provincial, and municipal journals. Among them, the papers on "Diagnosis and Treatment of Coal Mine Eye Injuries" and "Clinical Diagnosis and Treatment of Pediatric Eye Injuries" were presented and published at international ophthalmology conferences, earning praise from peers. He has received multiple awards in science and technology.

Is there a connection between floaters and kidney deficiency?
In Western medicine, floaters are not significantly related to kidney deficiency, and the concept of kidney deficiency in Chinese medicine is different from that in Western medicine. Therefore, the treatment for floaters primarily involves resting sufficiently, reducing close-up work to alleviate eye strain, using eyes correctly, and appropriately using some peptide iodine eye drops, which generally yield good results. If the floaters are pathological, it is necessary to visit an ophthalmology department for further examination, including an eye ultrasound, fundus photography, intraocular pressure, uncorrected visual acuity, and corrected visual acuity, to actively treat and monitor the development of the vision, aiming to restore normal vision.
Will staying up late worsen night blindness?
If night blindness is caused by congenital reasons, then staying up late generally does not significantly worsen it. If it is caused by acquired eye abnormalities, staying up late will noticeably exacerbate the occurrence of night blindness. Additionally, if it is caused by a deficiency in vitamin A, one should rest properly, reduce close-range activities, avoid staying up late, and supplement with foods or medications containing vitamin A. If the night blindness is due to eye-related causes, active treatment and regular follow-ups are recommended. If it is due to congenital reasons, currently there are no particularly effective treatments available.
Can slit lamp examination detect floaters?
Floaters generally do not require examination with a slit lamp microscope; they are examined using A-scan or B-scan ultrasonography to assess the extent of vitreous opacity, posterior vitreous detachment, and the status of the vitreous in relation to the retina. Floaters are also known as vitreous opacities and can be categorized into physiological and pathological vitreous opacities. Physiological vitreous opacities generally do not affect vision but appear as some floating objects in front of the eye, which do not change vision. These are more visible in bright light and less visible or absent in low light. If the vitreous opacity is pathological, it can affect vision and requires further ophthalmologic examination and active treatment.
Can a retinal detachment be treated after one year?
If retinal detachment is discovered or diagnosed only after a year, the effectiveness of surgical treatment tends to be poorer. However, if there is no eyeball atrophy, no corneal, lens, or vitreous abnormalities at this time, surgery to reposition the retina can still be considered first, followed by assessment of vision recovery. Additionally, an ophthalmic examination should be conducted, including tests like uncorrected visual acuity, corrected visual acuity, intraocular pressure, ocular B-ultrasound, and fundus photography, to decide and predict the outcome of the surgery and post-operative conditions. Nevertheless, even if a year has passed since the retinal detachment occurred, active treatment should still be pursued, and one should not give up.
Do both eyes undergo strabismus surgery at the same time?
Whether strabismus surgery is performed on one eye or both eyes at the same time depends on the degree of strabismus, the condition of the dominant eye, and the nature of the strabismus, such as concomitant strabismus, paralytic strabismus, etc. It needs to be decided whether one eye or both eyes should be operated on. If the degree is quite severe, operating on the muscles of one eye may not resolve the issue, and it might be necessary to operate on the muscles of the other eye as well. However, a maximum of three rectus muscles can be operated on in one eye at the same time. Operating on more can lead to some complications. Therefore, whether to operate on one eye or both eyes should be determined based on the patient's actual condition.
The difference between floaters and cataracts
Floater disease is a vitreous opacity, while cataract is a lens opacity; these two conditions are not the same issue. Vitreous opacities can be classified as physiological or pathological. Physiological vitreous opacities appear as moving objects in front of the eyes, which are less noticeable in the dark and more noticeable under bright light; cataracts gradually affect vision. Physiological vitreous opacities in floater disease generally do not affect vision, but pathological vitreous opacities do affect vision. An eye ultrasound shows severe vitreous opacities and retinal changes, whereas the cloudiness in the lens, namely cataracts, usually means the vitreous and retina are normal.
Can flying mosquito disease be treated with a hot compress on the eyes?
Floaters can completely be treated with warm compresses on the eyes, but if the purpose is to treat floaters, then it is meaningless because warm compresses have no effect on the treatment of floaters. Floaters can be divided into physiological floaters and pathological floaters. Physiological floaters do not affect vision at all; one cannot see clearly in dark places, but can see floaters in bright conditions. In such cases, it is only necessary to ensure adequate rest, use eyes properly, and appropriately use medicines like Ammonium Iodide Peptide Eye Drops, or Phosphatidylcholine Complex Iodine Tablets. If it is a pathological vitreous opacity, one should visit the ophthalmology department for thorough examinations and active treatment to strive for the restoration of vision. (Please use medication under the guidance of a physician.)
The difference between trachoma and conjunctival concretions.
Trachoma is caused by Chlamydia infection, while eye concretions are generally caused by chronic inflammation leading to lipid accumulation. When the eyelids show symptoms of trachoma, proliferative follicles and proliferative tissues in the eyelids form cobblestone changes. The concretions are white and located subconjunctivally, generally deep enough not to affect the eyes, but if superficial, they protrude into the palpebral conjunctiva and can cause certain wear to the eyes. Symptoms such as a foreign body sensation, burning sensation, and increased secretions can result from both trachoma and eye concretions. For treatment, eye drops are used for trachoma, and the eye concretions are removed under topical anesthesia, which alleviates the symptoms.
Can flying mosquito syndrome be detected by B-ultrasound?
Floaters, also known as vitreous opacities, can be categorized into physiological and pathological vitreous opacities. Physiological vitreous opacities generally do not affect vision, whereas pathological vitreous opacities can severely impact vision. In cases of physiological vitreous opacities, patients typically see unfixed, floating objects in their vision, which vary in shape and become more noticeable in bright light, but less clear in the dark. Examinations mainly include ocular B-ultrasound, fundus photography, and fibroscope examination, which can fully assess the extent of vitreous opacity. Once vitreous opacities occur, it is important to rest, seek active treatment, and have regular follow-up examinations.
