What is the meaning of macular central light reflection disappearance?

summary

Macular edema refers to the inflammatory reaction and liquid infiltration in the macular area, which is the most sensitive part of the retina to light. Central retinal vein occlusion, diabetic retinopathy, central serous chorioretinopathy, uveitis and other ocular manifestations. It is usually caused by diabetes, retinal vein occlusion, uveitis, cataract after intraocular lens surgery and other reasons, which is one of the important causes of vision loss. Macular edema symptoms? Let's talk about it.

What is the meaning of macular central light reflection disappearance?

The early lesions can be normal under the ophthalmoscope, and the fovea light reflection is diffused or disappeared. During the course of the disease, the retinal edema area showed different degrees of reflection enhancement or silk like reflection, retinal thickening. In the late stage, macular edema showed honeycomb or cystic appearance. The thickness of retina wall was uneven, and the internal separation and vascular shadow could be seen. Some vesicles can be very thin, even form a hiatus.

It is difficult to diagnose cystoid macular edema by ophthalmoscope alone. We should use ophthalmoscope combined with trihedral lens or slit lamp plus front lens-90d lens to examine the macular area by using the narrow slit of slit lamp. We can see the retinal thickening and vascular shadow in the macular area. When we use the rear reflection to irradiate, we can sometimes see that the macular area has a honeycomb appearance and the retina has a cystic space.

Fundus fluorescein angiography (FFA) is an essential method for the diagnosis of cystoid macular edema (CME). It is the most commonly used method for the diagnosis of CME. It is also the gold standard for the diagnosis of CME. In recent years, optical coherence tomography can clearly show the appearance of cystoid macular edema in the posterior pole, which is also one of the best methods to diagnose cystoid macular edema.

matters needing attention

For a small number of non-specific and non-inflammatory cystoid macular edema, it is not suitable to use glucocorticoids or laser treatment, such as Irvine gass syndrome and idiopathic cystoid macular edema, acetazolamide and indomethacin can be given orally. Acetazolamide and other carbonic anhydrase inhibitors can reduce macular edema caused by various reasons.
