An example of adenoviral gene therapy in the human diabetic organ-cultured corneas is presented towards the normalization of delayed wound healing and markedly reduced epithelial stem cell marker expression in these corneas. It also describes the optimization of this process in stem cell-enriched limbal epithelial cultures.

Creating experimental retinal detachments with a reproducible and sustained height of detachment, and without subretinal hemorrhage, is important for studying the pathophysiology of photoreceptor cell loss in retinal disease and evaluating potential therapeutic interventions. Here, we report such a method in detail.
FAQs
The corneal endothelium normally removes fluid from the stroma through active pumping. When endothelial cell loss or damage reduces this capacity, fluid accumulates and produces stromal swelling. If the imbalance persists, edema can extend into the epithelium, where fluid-filled bullae develop and may later rupture, worsening surface discomfort.
Bullae create pain and visual disturbance because they affect the normally clear corneal surface. As epithelial edema progresses, fluid-filled blisters disrupt the surface and can rupture, while underlying corneal swelling reduces optical clarity. Symptoms therefore reflect both surface injury and reduced transparency, rather than endothelial dysfunction alone.
Previous intraocular surgery, glaucoma, and endothelial dystrophies are common associations. These conditions provide important clinical context when endothelial dysfunction and persistent corneal swelling occur. Recognizing them can help clinicians relate the corneal findings to prior eye procedures or disorders affecting the endothelial cell layer.
Initial management may focus on relieving symptoms with hypertonic saline, protective contact lenses, or pain control. These measures address the discomfort and surface complications associated with corneal edema and bullae, but they do not restore lost endothelial function. Their role is therefore primarily supportive while the disease is assessed or managed.
Endothelial keratoplasty or another corneal transplantation procedure may be used when Bullous Keratopathy is advanced. Unlike symptom-focused measures, these procedures can restore corneal clarity by addressing the diseased cornea at a surgical level. The treatment is especially relevant when persistent swelling and surface bullae continue to impair vision.
Supportive treatments such as hypertonic saline, protective contact lenses, and pain control are intended to relieve symptoms. Endothelial keratoplasty and other transplantation procedures have a different goal: restoring corneal clarity in advanced disease. This distinction helps separate temporary or supportive symptom management from treatment directed at visual recovery.
