Abstract
Objective
To observe the expression of VEGF in the postoperative late vitreous hemorrhage (LVH) after vitrectomy for proliferative diabetic retinopathy (PDR) patients, and how VEGF level changes in patients with LVH (74 weeks) .
Methods
Seventy-three patients (82 eyes) with PDR who underwent vitrectomy were analyzed retrospectively. Vitreous samples were collected from eyes undergoing primary vitrectomy and from eyes with LVH undergoing second vitrectomy. Vitreous VEGF levels were measured using ELISA. According to the occurrence or absence of LVH after PPV, the patients were divided into the non LVH, LVH groups, and the patients with intraocular foreign body injuries who needed emergent intraocular surgeries were served as the normal control.
Results
LVH occurred in 19 (23%) of 82 eyes, and 5 eyes (6%) required second vitrectomy. VEGF level was significantly higher in PDR patients than that in normal control (P <0.01), was significantly higher in LVH than that in non LVH (P <0.05), (P <0.01).
Conclusions
In patients with PDR, high intraocular VEGF level after primary vitrectomy was identified as a risk factor of postoperative LVH. Persistent overproduction of intraocular VEGF may be associated with postoperative LVH.
Key words:

China Practical Ophthalmology was founded in May 1983. It is supervised by the National Health Commission of the People's Republic of China, sponsored by the Chinese Medical Association and China Medical University, and publicly distributed at home and abroad. It is a national-level excellent core academic journal of comprehensive ophthalmology and a series of journals of the Chinese Medical Association.
China Practical Ophthalmology aims to guide and improve the theoretical level and actual clinical diagnosis and treatment ability of frontline ophthalmologists in my country. It is characterized by close integration with clinical practice, and timely publishes academic articles and scientific research results with high practical value to clinicians, so that readers can understand and use them, improve the theoretical level and diagnosis and treatment ability of ophthalmologists, help and support their innovative development, and is deeply welcomed and loved by ophthalmologists and readers.
