The result of the left eye COT test, what does it mean?

Patient's question:

Patient: Male, 28 years old. On August 21, 2010, his left eye was injured by a hard object. At that time, there was bleeding from the upper eyelid of the left eye, and his vision was 0. Half an hour later, the upper eyelid of the left eye was sutured at the ophthalmology department of People's Hospital, and he was hospitalized for treatment. Ten days later, there was no significant improvement in vision. Further examination revealed that the fundus angiography results showed contusion and injury to the macular area of the retina, with bleeding in the upper temporal retina. Later, he went to Zhongshan Hospital in Guangzhou for examination and underwent OCT, which showed that the macular area and surrounding retina of the left eye were thinned, the photoreceptor band was absent, the superficial detachment of the neural epithelium in the upper part was present, and the RPE/choroidal band was thickened with enhanced reflection.

Doctor's answer:

Analysis of the condition: The retina is composed of the nervous epidermal layer and the pigment epithelial layer. There is a potential cavity between these two layers. When inflammation, trauma, and other multiple triggers occur, the structure of the two layers of the retina may separate.
Advice: Your condition is likely due to trauma causing the separation of the nervous epidermal layer and the pigment epithelial layer of the retina. Current treatment focuses on nourishing the nerves and improving retinal blood circulation, which falls under conservative treatment. At present, there is no faster or more effective method of treatment. It is recommended that you adhere to medication, maintain a regular lifestyle, and avoid excessive psychological burdens.
