“…1,2,12 Among the eye problems, epiphora is the most common which is suggested to be due to the nasolacrimal duct obstruction. 13 The nasolacrimal duct obstruction can be either congenital or acquired. The acquired is further divided into primary and the secondary acquired nasolacrimal duct obstruction.…”

“…The etiology of primary acquired nasolacrimal duct obstruction (PANDO) is said to be multifactorial, the major factors are due to anatomical, hormonal, environmental. 4,13 The secondary acquired obstruction may be due to neoplasms, trauma, infections and dacryolyths. 14 Alexandrakis et al have reported two cases of NLD obstruction due to ectopic eruption of the teeth.…”

“…8 While comparing the present findings with studies done in UK and other European countries, the findings was smaller than latter studies. 13,25 The differences in the measurement may be due to racial, geography, sample size too. The variation of the results may also be due to variation of slice thickness, different CT protocol, scanners used.…”

Post caesarean pelvic abscess is a rare complication which may present without typical features of endometritis. It should remain as one of the differential diagnoses in any patient with refractory puerperal fever. Despite the use of antibiotic prophylaxis, it still can occur causing significant maternal morbidity requiring a complicated course of management with the need of an intensive care unit, drainage of pus under ultrasound guidance or sometimes may need surgical re-exploration or even hysterectomy. We report a case of pelvic abscess in a young lady following caesarean section who presented with puerperal pyrexia. She did not respond to broad spectrum antibiotic treatment and underwent ultrasound-guided transabdominal drainage of the pelvic abscess following which she had rapid clinical improvement and good recovery.

“…Besides these clinical studies, there were a few radiologic studies focusing on morphometry of the NLD. [1,5,6,21] Ela et al [6] studied the morphometry of NLD on children, while Czyz et al [5] examined the NLD morphometry according to aeration grades in adult participants. However, they could not find any significant differences for morphometric values of the NLD between age and genders.…”

Objectives: Obstructions are very commonly seen in nasolacrimal duct before it opens into the inferior nasal meatus. Detailed anatomical knowledge of the nasolacrimal duct is crucial for physicians to understand the etiology of the obstructions, to plan ideal management option and to reduce unexpected iatrogenic injuries during surgeries. The aim of this study was to investigate morphometric properties of the nasolacrimal duct on computed tomography images. Methods: Three-dimensional computed tomography (3D-CT) of 142 adults (65 females, 77 males) were retrospectively evaluated. Antero-posterior cranial diameter, antero-posterior and transverse diameters and vertical angle of the nasolacrimal duct, distance between distal end of the nasolacrimal duct to anterior surface of the maxilla were measured and the differences evaluated statistically between right and left sides and among females and males and among different ages. All measurements were done using Osirix-Lite version 9 software. Results: None of the morphometric parameters of the nasolacrimal duct showed significant differences between right and left sides. Antero-posterior cranium and transverse diameter of the nasolacrimal duct were longer in men than women. Conclusion: Determining to morphometric properties of the nasolacrimal canal has advantages for understanding the etiology of the NLD obstructions, deciding the ideal surgical technique and reducing to unexpected injuries during surgeries related with this region.
