“…The lesion appears as an anechoic, fluid-filled cystic area on the internal edge the orbital cavity. (18) However, the amniotic fluid by itself is not able to dilate the lacrimal sac, especially when the bulging occurs days after birth. The term mucocele is used when the lacrimal sac is filled with mucus.…”

The dacryocystocele represents a rare congenital anomaly in the medial region of the orbit caused by distal obstruction (Hasner valve) and proximal (valve Rosenmüller) RESUMOA dacriocistocele representa uma rara anomalia congênita da região medial da órbita, causada pela obstrução distal (ao nível da válvula de Hasner) e proximal (ao nível da válvula de Rosenmüller) da via lacrimal, com subsequente dilatação do saco lacrimal. Recebe o nome de mucocele, quando seu conteúdo representa muco, ou amniocele, quando o seu conteúdo é preenchido por fluido amniótico. Acomete somente 0.1% das crianças, com obstrução do ducto lácrimonasal, sendo comumente unilateral e mais frequente no sexo feminino e com predisposição familiar. O diagnóstico é realizado pelas características clínicas: lesão cística tensa, abaixo do tendão cantal medial, de coloração azulacinzentada, rósea ou vermelha acompanhada por epífora desde o nascimento. No entanto podemos utilizar exames de imagem para diagnosticar esta anomalia congênita tais como: tomografia computadorizada, ressonância magnética e ultrassonografia.Descritores: Obstrução dos ductos lacrimais/congênito; Obstrução dos ductos lacrimais/diagnóstico; Obstrução dos ductos lacrimais/terapia; Obstrução dos ductos lacrimais/ultrassonografia; Cisto epidérmico; Cisto dermóide; Relatos de casos

“…A normal adult canaliculus measures 8 mm long and 0.5 mm wide [7,12] and transports lacrimal secretions from the punctum to the common canaliculus which enters the lacrimal sac through the valve of Rosenmuller. The canalicular lining con sists of nonkeratinizing stratified squamous epithelium [12,13] with a gradual transition to the stratified columnar epithelial cells lin ing the lacrimal sac.…”

“…Canalicular enlargement can result from diverticuli [1,2], cysts [2], neoplasms [3,4], or acute canaliculitis [2,[5][6][7][8][9][10][11], Rarely, a mucocele [2,5,9] or encysted abscess [2,10,11] will develop secondary to canaliculitis. Although Brady [5] and von Herrenschwand [9] have previously described canalicular mucoceles, in neither study was the source of canalicular fluid determined or the histopathology available.…”

We report a rare case of acquired canalicular cystocele in a patient with obstructions at both the proximal and distal ends of the inferior canaliculus. Histopathologic examination revealed a dilated tubule lined with nonkeratinizing squamous epithelium that measured 19 mm long and 7 mm wide. No mucous secreting goblet cells were observed in any sections. The fibrotic, thickened wall was infiltrated with epithelioid, lymphoid, and occasional plasma cells.

“…Examination was performed on both sides. The line from the inferior part of the tarsus to the arcus marginalis was the anatomic neutral position of the orbital septum (Jones 1976;Jones 1970;Montandon et al, 1990;Levine 1996). The thickness of the preseptal area was measured from the skin surface to the arcus marginalis.…”

Introduction: Orbital preseptal thickness is an important parameter not only in diagnosis of orbital cellulitis but also in recent classification and management of dark eye circle (DEC). Objective: The aim of this study was to evaluate normal preseptal thickness and collect baseline data in normal skin in a given population with no orbital pathology. Materials & method: Ultrasound was performed on 42 patients (23 females and 19 males) with clinically normal eyes and orbits for evaluation of normal orbital preseptal thickness. The age ranged between 15 to 35 years with a mean age of 24.9 years. Results: Our study concluded that normal preseptal thickness ranged from 2.1 mm to 5.5 mm. Mean preseptal thickness for both sides was 3.9 mm. Conclusion: Ultrasound can be used as quick, reliable and cost-effective modality for evaluation of orbital preseptal thickness.
