Objective:To explore the relevant anatomical factors in the pathogenesis of chronic dacryocystitis based on CT radiomics. Methods:A retrospective analysis was conducted on the general data and sinus CT materials of 85 patients with chronic dacryocystitis（case group） admitted to our department from December 2020 to December 2023, and 85 individuals undergoing physical examination（control group） during the same period. The differences in anatomical parameters between the two groups were compared to study the morphological characteristics of the nasolacrimal duct in patients with chronic dacryocystitis. Univariate and multivariate logistic regression analyses were used to explore the relevant anatomical factors in the pathogenesis of chronic dacryocystitis. Results:There were statistically significant differences（P<0.05） in the proportion of combined nasal septal deviation, the distance between the anterior and posterior ridges of the lacrimal fossa, the angle between the long axis of the nasolacrimal duct and the projection on the midsagittal plane, the maximum transverse diameter of the bony nasolacrimal duct, the maximum cross-sectional area of the bony nasolacrimal duct, and the thickness of the frontal process of the maxilla between the two groups. There were no statistically significant differences（P>0.05） in whether there was a combined high-position nasal septal deviation, whether there was a combined non-high-position nasal septal deviation, and whether there was a combined pneumatized middle turbinate. Multivariate analysis showed that nasal septal deviation, the distance between the anterior and posterior ridges of the lacrimal fossa, the angle between the long axis of the nasolacrimal duct and the projection on the midsagittal plane, and the maximum cross-sectional area of the bony nasolacrimal duct are independent anatomical factors affecting the pathogenesis of chronic dacryocystitis. Conclusion:Nasal septal deviation, a large distance between the anterior and posterior ridges of the lacrimal fossa, a large angle between the long axis of the nasolacrimal duct and the projection on the midsagittal plane, and a small maximum transverse diameter of the bony nasolacrimal duct are important anatomical bases for the pathogenesis of chronic dacryocystitis, providing a basis for an in-depth understanding of the disease occurrence.

BACKGROUND: Hasner valve incision has been recently introduced as a new treatment for ophthalmic patients with epiphora symptoms. The aim of this study was to examine whether surgical outcomes of Hasner valve incision for inferior nasolacrimal duct obstruction were different between pediatric and adult patients. METHODS: A total of 53 eyes of 52 patients who underwent Hasner valve incision in the Beijing Tongren Hospital from October 2016 to November 2019 were retrospectively observed. Patients were divided into two groups, including pediatric group (23 eyes of 22 patients, <18 years old) and adult group (30 eyes of 30 patients, ≥18 years old). Success rate of surgery was determined by both subjective measure (complete resolution of epiphora) and objective measure (lacrimal passage irrigation and tear meniscus height). Fisher exact test was conducted. RESULTS: By conducting Fisher exact test and comparing complete resolution of epiphora (P = 0.627), lacrimal passage irrigation (P = 0.663), measurement of Tear Meniscus Height (P = 0.561), and appearance of complication (P = 0.339), there was no statistically significant difference of surgical outcomes between pediatric and adult patients (P > 0.05). CONCLUSION Hasner valve incision was effective for both adult and children with inferior nasolacrimal duct obstruction, with no difference in surgical outcomes between the two groups.

Cornelia de Lange syndrome (CdLS) is a rare multisystemic disorder that is characterized by mental retardation, prenatal and postnatal growth retardation, limb anomalies, and distinctive facial features, which include arched eyebrows that often meet in the middle (synophrys), long eyelashes, low-set ears, small and widely spaced teeth, and a small and upturned nose. Ophthalmic manifestations include long eyelashes, nasolacrimal duct obstruction, myopia, ptosis, and strabismus. There has been no report of surgical treatment for esotropia and unilateral ptosis in patients with CdLS in Korea. I report a patient with CdLS who underwent surgical treatment for esotropia and unilateral ptosis with a good surgical outcome.

PURPOSE: To investigate the efficacy and factors affecting the success rates of nasolacrimal probing and silicone intubation (SI) in patients with congenital nasolacrimal duct obstruction (CNLDO). METHODS: We retrospectively reviewed the medical records of patients including 69 eyes of 59 patients who received probing and 61 eyes of 49 patients who received SI. In patients with probing, the age, sex, and history of conservative treatment were analyzed in the success and failure groups, and a success rate comparison was conducted by dividing these values into postnatal group 1 (< 6 months), group 2 (6–12 months), and group 3 (≥ 12 months) following their age. In patients with SI, the age, sex, retention period of the tube, and history of probing and conservative treatment were analyzed in the success and failure groups. RESULTS: In the failure group involving probing, the average age was significantly higher compared with the success group (p = 0.005), and the success rate of group 3 was significantly lower compared with group 2 (p = 0.005). In the failure group involving SI, the age was significantly higher (p = 0.015); however, the retention period was shorter (p = 0.006), and the history of probing also showed a statistically significant difference between the two groups (p = 0.009). Logistic regression analysis showed that the age and history of probing had an effect on the success rate (p = 0.049 and p = 0.047, respectively); however, the retention period was not statistically significant (p = 0.411). CONCLUSIONS: In patients with CNLDO > 12 months, the success rate of probing was lower than in patients < 12 months, and probing might have an effect on the success rate of future SIs. It is therefore recommended that SI be preferentially performed on patients > 12 months.

PURPOSE: To determine the frequency of ocular diseases in infants visiting the ophthalmology department of a tertiary care hospital. METHODS: This was a cross-sectional descriptive study conducted in the department of ophthalmology, Abbasi Shaheed Hospital, from January 2015 to May 2016. The study included 377 infants ranging in age from 1 day to less than 1 year who were, selected by a nonprobability consecutive sampling technique. A detailed history was taken, and a complete ocular examination was performed. Descriptive statistics were used to calculate the mean and standard deviation for age. Frequencies were calculated for ocular diseases along with the percentages. Outcome variables included various congenital and acquired diseases such as conjunctivitis, congenital cataract, glaucoma, nasolacrimal duct blockage, squint, trauma, and fundus abnormalities. RESULTS: The mean age of infants was 5.0 ± 3.7 months. There were 196 (52%) males and 181 (48%) females. The sample included 330 (87.5%) full term infants. Acquired ocular diseases occurred in 230 (61%) infants; and congenital diseases, in 147 (39%). The most common ocular disease was conjunctivitis, which occurred in 173 (46%) infants, followed by congenital blocked nasolacrimal duct, which occurred in 57 (15 %) infants. Conjunctivitis was more common among neonates than infants. CONCLUSIONS: Acquired ocular diseases were more common than congenital ocular diseases. The most common ocular pathology was conjunctivitis, followed by congenital nasolacrimal duct obstruction, in infants. Conjunctivitis was more common in neonates than infants.

BACKGROUND AND OBJECTIVES: Various surgical approaches have been employed for the complete resection of inverted papilloma (IP) of the nose and paranasal sinus. Sacrificing the inferior turbinate (IT) and nasolacrimal duct (NLD) is often unavoidable due to the anatomy of maxillary sinus. However, the prelacrimal recess approach (PLRA) provides a wider entrance to the maxillary sinus without the ablation of NLD and IT. We present seven cases of IP successfully treated by the PLRA. SUBJECTS AND METHOD: We collected data from seven different cases involving patients who underwent resection of IP by means of the PLRA from 2016 to 2017. If the lesion could not be removed first via middle meatal antrostomy (MMA), then PLRA was attempted. The surgical specimens were all confirmed to be IP. RESULTS: Preoperative imaging studies demonstrated that the lesions of IP were located mainly in the maxillary sinus. All of the seven patients had unilateral lesions and all tumors were completely resected via PLRA. The follow-up ranged from 3 to 24 months, during which no recurrence or complications were observed in any of the seven patients. CONCLUSION: PLRA provides an adequate operation field without unfavorable scars. It allows the preservation of sinus structure and function. PLRA is feasible and can be used for the diffuse maxillary sinus IP.

PURPOSE: We report a case of acute dacryocystitis diagnosed with abscess and rupture of lacrimal sac and fistula to posterior orbit during the operation. CASE SUMMARY: A 71-year-old woman visited our clinic with edema and pain in the eyelid from three days ago. For past four months, there was viscous of the left eye and tears. The patient had severe conjunctival chemosis and hyperemia, compared with the left eyelid edema and redness. Orbital CT scan showed orbital cellulitis, which was followed by systemic antibiotics and steroid therapy. On the 4th day of therapy, orbital abscess formation was observed in orbit MRI and surgical drainage was planned. During surgery, we found rupture of the posterior part of lacrimal sac and fistula to posterior orbit. Pseudomonas aeruginosa was identified in the bacterial cultures, and after the administration of appropriate antibiotics, the disease showed improved progress, and then additional dacryocystorhinostomy was performed. CONCLUSIONS: In our case, acute dacryocystitis rarely spread in orbit, which may lead to delayed diagnosis, orbital cellulitis and abscess, resulting in serious complications of vision threat. So, we think that it is necessary to consider surgical treatment more actively in the stage of chronic dacryocysitis.

PURPOSE: Congenital double puncta are usually unilateral, and the accessory punctum exists on the medial side in a slit configuration that is distinct from the shape of the normal punctum. We report a case of an unusual case of double lacrimal puncta which the lateral, rather than the medial, punctum was judged to be the accessory punctum. CASE SUMMARY: A 39-year-old male patient with no underlying disease and no ophthalmologic history visited our clinic with right eye epiphora of 2 weeks duration. On slit lamp examination, double puncta were observed in the right lower eyelid and the remaining puncta were normal. On lacrimal syringing test and dacryocystography were performed and revealed incomplete obstruction with partial narrowing of the nasolacrimal duct. Silicone tube intubation was performed through the right lower medial punctum and symptoms improved postoperatively. CONCLUSIONS: The present case is an unusual case of double lacrimal puncta which has not been reported in Korea. Unlike the previous literature, the lateral, rather than the medial, punctum was judged to be the accessory punctum. Because accessory punctm can be present on the lateral side, it is necessary to distinguish between the accessory punctm and the main punctum through the accurate dacryocystography and lacrimal syringing test for the treatment of the patient.
