Patient discussion about bleb

Q. What's the best treatment for a blister?

A. use a clean needle and poke a small hole right at the base, between normal skin and the blister. Push the blister down, allow it to drain completely and put a bandaid over it; don't ever rip off blister skin allow it to fall off or reattach naturally.

Q. What are the causes of viral blisters on the skin? For a few months now I've been having these hard viral blisters on my fingers. The only way to get rid of them is with freezed carbon. It does go away with that treatment- after a few weeks but then a new one appears. How can I prevent it from "attacking" again??

A. These viral blisters you are describing are caused by HPV (papilloma virus), and are very hard to get rid of without treatment with freezed carbon. Many of us have the virus but not everyone gets the actual infection. There is not a proved way of preventing from it to happen again after treatment, unfortunately..

The main goal in surgical management is resection of bullae and blebs and apical pleurodesis to prevent recurrence.
Till now, trabeculectomy is still the most efficient option for those with progressive glaucoma.[6] Cicatrix is the major cause of postoperative bleb failure and significantly affects the long-term success rate of trabeculectomy.[7],[8],[9],[10] The use of antimitotic agents such as 5-fluorouracil and mitomycin C (MMC) has been widely accepted as the golden standard of trabeculectomy, apparently reducing the incidence of scar formation and enhancing bleb surviving rate.

The conjunctiva was penetrated, apart from the bleb, using a 30 G needle, and Healon V (AMO Japan, Tokyo, Japan) was injected into the bleb.
She was subsequently diagnosed with blue rubber bleb nevus syndrome based on clinical and endoscopic findings.
The superficial scleral flap was then loosely sutured to the sclera, and HealaFlow was injected under the flap to create a filtering bleb. In PC, the superficial flap was sutured tightly in order to prevent leakage and subsequent bleb formation with interrupted 10-0 monofilament nylon suture.

It is hypothesized that the heat generated from the ablation procedure stretches the small fenestrations or leads to perforation of preexisting blebs of the diaphragm [9].
(i) At day 1: (1) blebs were elevated and with significant hyperemia ([??] indicates elevated bleb); (2) the connective tissue of the bulbar conjunctiva was markedly oedematous and loose and vascular dilation and congestion were obvious, with an abundance of infiltrating neutrophils.
Bleb failure can occur after trabeculectomy for various reasons, but the most common cause is fibrotic changes in the conjunctiva and episclera.
Computed tomography (CT) scans can be used to detect patients with small pneumothorax and the number, size, location of bullae or blebs. Therefore, pleural adhesion, pleural fluid and underlying pulmonary diseases are detected with CT scans.7 Patients with PSP are treated with surgical or non- surgical procedures.
