Individuals with corneal endothelium dystrophy may experience vision disturbances and corneal edema.​ Diagnosis involves specialized tests like specular microscopy and pachymetry to assess the cornea’s endothelial cell layer.​

Vision Disturbances

Corneal endothelium dystrophy can lead to vision disturbances such as blurred or hazy vision, glare sensitivity, and reduced visual acuity. As the condition progresses, individuals may notice worsening vision quality and difficulty with tasks like reading or driving due to corneal abnormalities affecting light transmission.​

Corneal Edema

Corneal endothelium dystrophy can cause corneal edema, leading to the buildup of fluid in the cornea and resulting in swelling.​ This can further impair vision by distorting the cornea’s shape and transparency, contributing to symptoms like increased glare, halos around lights, and discomfort due to the altered corneal structure.​

Diagnostic Tests (e.​g.​, specular microscopy, pachymetry)

Diagnostic tests such as specular microscopy and pachymetry are utilized to assess the corneal endothelium in cases of dystrophy.​ Specular microscopy allows for the evaluation of endothelial cell density and morphology, while pachymetry measures corneal thickness to detect edema or abnormalities, aiding in the diagnosis and monitoring of corneal health.​

Treatment Options for Corneal Endothelium Dystrophy

Treatment options for corneal endothelium dystrophy include medications, Descemet’s Stripping Endothelial Keratoplasty (DSEK),
and Endothelial Keratoplasty (DSAEK/DMEK), aimed at managing symptoms and improving corneal clarity.​

Medications and Eye Drops

Medications and eye drops may be prescribed to manage symptoms of corneal endothelium dystrophy.​ Hypertonic saline solutions or ointments can help reduce corneal edema, while anti-inflammatory drugs can control inflammation.​ These treatments aim to improve corneal clarity and alleviate discomfort associated with the condition.​

Descemet’s Stripping Endothelial Keratoplasty (DSEK)

Descemet’s Stripping Endothelial Keratoplasty (DSEK) is a surgical procedure used to replace damaged endothelial cells in the cornea. During DSEK, the dysfunctional endothelium is removed and replaced with a thin layer of donor tissue, promoting corneal clarity and improving vision in individuals with corneal endothelium dystrophy.​

Endothelial Keratoplasty (DSAEK/DMEK)

Endothelial Keratoplasty procedures like Descemet’s Stripping Automated Endothelial Keratoplasty (DSAEK) and Descemet Membrane Endothelial Keratoplasty (DMEK) involve selective replacement of the cornea’s endothelial layer with donor tissue.​ These surgeries are aimed at restoring optimal corneal function and visual acuity in individuals with corneal endothelium dystrophy;
