![]() At that serial expression when liquid secretion is first observed, it then takes approximately half of the time required to drain the gland originally to redrain the gland, indicating a partial recovery. After a central optimally secreting gland has been drained of its liquid secretion, it takes a mean time of 2.17 ± 0.49 hours to again secrete liquid during waking hours, using the same amount of force to express the new liquid secretion. “The results show that a single central meibomian gland can be drained of its liquid secretion in 8-20 seconds upon application of a constant force of 1 g/mm 2. The only good study I could find to say it was superior is called the Bundle Method. How exactly should I do the warm compresses? Thus it may be better to do warm compresses more often (but not within 2 hours of each session–see below) 3 times a day instead of 2 times a day for as long as you can.ģ. But no one I know really has 15 minutes 2-3 times per day to do there warm compresses. For how long should I put the compress on?ĭr. They created the LIPIFLOW machine which provides steady state temperature of 42.5☌ for 12 minutes at the eyelid margin.įor daily cleaning, this means the water should be very warm but not hot enough to cause pain or burn the skin.Ģ. Based on the most conservative safety thresholds in the literature, temperatures below 40☌ will not result in thermal injury to the cornea or crystalline lens.(Reference 1 below) However, increasing temperature without safety controls raises the issue of potential thermal damage to the cornea. ![]() Therefore, each degree of temperature increase over 40☌ could be critical in melting severely obstructed material. Only using mildly war m water may not be adequate to relieve the meibomian gland obstruction. Reported melting temperatures of normal meibomian secretions vary significantly with the majority of reports ranging from 32 to 40☌ severely obstructed meibomian glands have considerably higher melting points. Blackie, who are excellent optometrists, have done the most research on this question that I could find thus far: Conservative therapy for chalazia: is it really effective? Acta Ophthalmol.But there is some data to answer some of these questions:ĭr. Wu AY, Gervasio KA, Gerdoudis KN, Wei C, Oestreicher JH, Harvey JT. Chalazion-induced hyperopia as a cause of decreased vision. Santa Cruz CS, Culotta T, Cohen EJ, Rapuano CJ. Conservative treatment of chalazia Ophthalmology 1980 87(3):218-21 Multivariate analysis of the effect of Chalazia on astigmatism in children. Effects of chalazia on corneal astigmatism : Large-sized chalazia in middle upper eyelids compress the cornea and induce the corneal astigmatism. A prospective randomized treatment study comparing three treatment options for chalazia: triamcinolone acetonide injections, incision and curettage and treatment with hot compresses. Intralesional triamcinolone acetonide injection versus incision and curettage for primary chalazia: a prospective, randomized study. ![]() Incision and Curettage Versus Steroid Injection for the Treatment of Chalazia: a Meta-Analysis. *GRADE: Grading of Recommendations Assessment, Development and Evaluation ( Sources of evidenceĪycinena AR, Achiron A, Paul M, Burgansky-Eliash Z. ![]() (GRADE*: Level of evidence=low Strength of recommendation=strong) Regular lid hygiene for blepharitis (see Clinical Management Guideline on Blepharitis) When undertaking invasive procedures, optometrists should ensure that appropriate medical malpractice (professional indemnity) insurance and clinical governance arrangements are in place and the College of Optometrists guidance on expanded scope of practice is followed. However, these procedures should be undertaken in a suitable clinical setting to prevent cross-infection and mechanisms need be in place to access the required parenteral medicines. More invasive therapies, such as incision and curettage or steroid injections could be undertaken by appropriately trained optometrists for persistant chalazia, as older lesions are less likely to resolve with conservative therapies alone. If large, recurrent, causing corneal distortion or interfering with eyelid function, refer for management by ophthalmologist. Many chalazia resolve within 6 months with conservative management (warm compresses (at least 40-45☌ for 10 mins) and lid massage). ![]()
