Подскажите пожалуйста,как поэтапно и правильно делать инъекции при халазионе, в какой литературе можно это найти?

ranulomatous mass may be required.

If no evidence of infection is present, local intralesional injection of a steroid (eg, triamcinolone or methylprednisolone) can reduce inflammation and may cause regression of the chalazion within a few weeks. Typically, 0.2-2 mL of 5 mg/mL triamcinolone is injected directly into the chalazion’s center. A second injection 2-7 days later may be necessary for larger chalazia. [11] This technique appears to be safe and effective in the treatment of primary chalazia. [12]

Potential complications of steroid injections include hypopigmentation, atrophy of the area, corneal perforation and traumatic cataract, elevated intraocular pressure, a visible depot of medication, and potential exacerbation of bacterial or viral infection. To minimize the risk of such complications, soluble aqueous preparations are preferred to crystalline suspensions. A transconjunctival injection route may provide a further safeguard.

Я раньше делал инъекции кеналога в халазион, но последние года полтора стараюсь применять другие всем известные опции для лечения.

Retinal and choroidal vascular occlusion following intralesional corticosteroid injection of a chalazion.
Thomas EL, Laborde RP.
Abstract
Unilateral visual loss following periocular corticosteroid injection is a reported complication of injections of tonsillar, nasal, scalp, and retrobulbar sites. This is the first reported case, to our knowledge, of intralesional corticosteroid injection of a chalazion producing ipsilateral microembolization and infarction of retinal and choroidal vasculature. An eight-year-old boy underwent reexcision of an upper lid chalazion under general anesthesia. Intraoperatively, 0.5 ml of depot-steroid preparation was injected into the excision site. Postoperatively, vision was unilaterally reduced to light perception only. Examination revealed an afferent pupillary defect, retinal and choroidal emboli, retinal edema, and a macular "cherry red spot". Anterior chamber paracentesis, carbon dioxide rebreathing, carbonic anhydrase inhibitors and ocular massage failed to change the embolic pattern. No visual recovery resulted. Fundus photography and fluorescein angiography demonstrated occlusion of the retinal and choroidal vasculature. Extreme care should be exercised during and immediately following intralesional corticosteroid injection of chalazia.

[Intraocular ischemic infarcts in injections into the lid and parabulbar region (without perforation of the eye)].
[Article in German]
Meythaler FH, Naumann GO.
Abstract
Two outpatients presented with disseminated intraocular ischemic infarctions after injection into the lid and in retrobulbar regions. A 34-year-old patient suffered a sudden and permanent loss of vision due to segmental optic atrophy prior to a chalazion excision under local anesthesia in the right upper and lower lids, with 2 ml Novocain 2%. A 55-year-old patient received parabulbar injections of crystalline cortisone with additional Scandicain 1% in the temporal region of the lower lid. During the injection a sudden complete loss of vision occurred, due to an occlusion of the central retinal artery, resulting in a total simple optic atrophy with complete amaurosis. The disseminated intraocular ischemic infarctions appear to be primarily due to intra-arterial injections, where the ophthalmic artery acts as a "bridge artery" between the extracranial and intracranial circulation. The rise in pressure in the capillaries of the external carotid artery effects a reversal of the circulation, as a result of which embolizing material reaches the ophthalmic artery and its capillaries. It is difficult to decide what role locally admixed vasoconstrictive drugs play in individual cases in which air has accidentally been injected intravasally. Prophylactic measures are discussed.

Всё это просто результат элементарного нарушения техники инъекции. Хотя я тоже этот метод лечения особо не применяю.
