Efficacy and safety of super pulse CO2 laser-assisted punctoplasty with canalicular curettage in primary canaliculitis

The objective of this study was to evaluate the efficacy and safety of super pulse CO2 laser-assisted punctoplasty with canalicular curettage in primary canaliculitis. In this retrospective serial case study, the clinical data of 26 patients who underwent super pulse CO2 laser-assisted punctoplasty for the treatment of canaliculitis were collected from January 2020 to May 2022. The clinical presentation, intraoperative and microbiologic findings, surgical pain severity, postoperative outcome, and complications were studied. Of the 26 patients, most were females (female:male 20:6), with a mean age of 60.1 ± 16.1 years (range, 19-93). Mucopurulent discharge (96.2%), eyelid redness and swelling (53.8%), and epiphora (38.5%) were the most common presentations. During the surgery, concretions were present in 73.1% (19/26) of the patients. The surgical pain severity scores ranged from 1 to 5, according to the visual analog scale, with a mean score of 3.2 ± 0.8. This procedure resulted in complete resolution in 22 (84.6%) patients and significant improvement in 2 (7.7%) patients, and 2 (7.7%) patients required additional lacrimal surgery with a mean follow-up time of 10.9 ± 3.7 months. The surgical procedure of super pulse CO2 laser-assisted punctoplasty followed by curettage appears to be a safe, effective, minimally invasive, and well-tolerated treatment for primary canaliculitis.

Lateral tarsal strip versus lateral tarsal strip with three-snip punctoplasty for managing epiphora in involutional ectropion

PURPOSE

To compare the efficacy of two surgical techniques-lateral tarsal strip (canthoplasty) alone, and lateral tarsal strip with three-snip punctoplasty-in reducing epiphora arising from involutional ectropion with partial punctal stenosis.

METHODS

Fourty patients with involutional ectropion and partial stenosis of the lacrimal punctum were randomly allocated to two treatment groups. Group 1 patients received lateral tarsal strip alone with only non-invasive stenting of the punctum, and group 2 patients received tarsal strip plus three-snip punctoplasty. Subjective assessment of epiphora was achieved via completion of a quality of life (QoL) questionnaire preoperatively and at postoperative month 3. Eyelid position, adverse outcomes and corneal dryness (via Oxford grading scheme) were also assessed postoperatively. Only patients with unilateral problems were included in the study.

RESULTS

Forty eyes of 40 patients were included: 20 in each group. The mean ages of group 1 and group 2 patients were 79±11 and 80±9 years, respectively. All patients reported significantly reduced eye watering after surgery, with no significant intergroup difference in subjective outcomes, except that computer usage and night driving (P<0.05), improved in a more significant way in group 2. Eyelid malposition was corrected in all cases, there were no cases of postoperative punctal eversion, and no significant adverse events or complications occurred. Finally, the mean improvements in the dryness/keratitis score (using the Oxford scheme) were comparable between the 2 groups (P=0.34).

CONCLUSION

The study findings indicate that treatment of involutional ectropion with partial punctal stenosis by lateral tarsal strip with three snip punctoplasty does not provide greater reduction in discomfort secondary to epiphora than conventional lateral tarsal strip alone, except for specific situations such as night driving or computer use.

Primary canaliculitis: The incidence, clinical features, outcome and long-term epiphora after snip-punctoplasty and curettage

Purpose

To study the incidence, clinical features and outcome of primary canaliculitis with special reference to long-term epiphora after Snip–punctoplasty and curettage.

Methods

Single center, retrospective, telephonic questionnaire study. The medical records of patients who visited Orbit and Oculoplasty clinic, Tertiary Eye Hospital, India from 01 July 2011 to 31 June 2012 were analyzed. Records of the patients with primary canaliculitis were reviewed for clinical profile and management. Post-surgical patients thus identified were telephonically contacted in December 2012. Questionnaire was used to assess the postsurgical epiphora. Symptomatic patients were given clinic appointment, reassessed and managed.

Results

2245 patients visited Orbit and Oculoplasty clinic during the study period. The incidence of primary canaliculitis was 1.4% (31 patients). The median age of the patients with canaliculitis was 65 years (range, 14–80 yrs). Sixteen patients were male. All cases were unilateral and four eyes showed both upper and lower canalicular involvement. The commonest clinical presentations were pus or concretion from punctum (28), mucous discharge (23), epiphora (18) and conjunctival injection (18). Three snip punctoplasty and canalicular curettage was performed in 30 of these patients. Twenty of the 25 available culture results were positive and streptococcus species was the most common isolated organism. Records revealed that five (22%) of these patients had persistence of symptoms. Twenty-three patients could be contacted telephonically. The median follow-up of these patients was 11 months. On telephonic communication we found that two (8.7%) patients had epiphora. Munk epiphora score in these patients was three and one respectively.

Conclusions

Incidence of canaliculitis was 1.4%. Most common isolate was streptococcus species. Snip–punctoplasty and curettage is a safe and efficacious modality of treatment of canaliculitis. Post-operative epiphora occurred in 8.7% patients.
