ABSTRACT.Aim: We describe the technique and our results in managing lower eyelid involutional medial ectropion using a combination of lateral tarsal strip to address horizontal eyelid laxity, and transconjunctival inferior retractor plication to address inferior retractor dehiscence. Methods: Patients with symptoms of epiphora or signs of medial ectropion were offered this procedure. All had the following characteristics: medial lower eyelid eversion, punctal eversion >3 mm, medial canthal tendon laxity <4 mm, significant horizontal eyelid laxity and lacrimal systems that were patent to syringing. Results: A total of 24 eyelids of 17 patients underwent this procedure over a 12-month period. The mean age of the patients was 79.7 years; 11 were male and six were female. The mean follow-up time was 18 months. Two eyes had undergone previous surgery. All patients had restoration of the eyelid margin to the globe and relief of symptoms. No complications were noted. Discussion: These results suggest that excision of posterior lamellar tissue is not necessary for correction of involutional medial ectropion. Transconjunctival plication or reattachment of retractors is easy to perform and allows for the repair of more than the medial portion of the retractors if required.

Lacrimal scintigraphy (LS) or dacryoscintigraphy can demonstrate abnormalities in 80%-95% of patients with symptoms of epiphora and a patent lacrimal system on syringing and up to 40% asymptomatic individuals. Precise localization of the site of delay may not always be possible due to lack of anatomic detail on LS. LS is considered useful in patients with epiphora with delayed tear clearance and patency to syringing and suspected to have either nasolacrimal duct (NLD) stenosis or lacrimal pump failure. It remains unclear, however, as to whether LS can reliably distinguish between the two. The literature reports considerable variation in the technique, normative data, analysis, and interpretation of LS. Qualitative or visual analysis is simpler to perform and to our knowledge used more frequently in comparison to quantitative analysis. There is little extra information to be gained from LS in cases with complete NLD obstruction or severe NLD stenosis on syringing.

Posterior approach levatorpexy appears to be a safe and effective procedure for correction of congenital ptosis particularly with moderate or better levator function.

Good surgical outcomes are achievable training in en-DCR surgery. Adequate operating time needs to be planned. Failure was primarily due to closure of the soft-tissue ostium, either secondary to inadequate osteotomy and sac-marsupialisation or postoperative scarring. Intra-operative mucosal trauma is higher amongst trainees and adjuvant silicone stenting during the training period may be of value where mucosal adhesions are anticipated.

The purpose of this study was to measure the changes in intraocular pressure (IOP) and refraction following orbital decompression for thyroid orbitopathy.Methods:Retrospective review of 18 eyes in 10 consecutive patients who underwent orbital decompression including intraconal fat excision for proptosis secondary to thyroid orbitopathy. IOP using tonopen, exophthalmometry, autorefraction and autokeratometry measurements were performed at 1-week, 1-month and 3-months after surgery.Results:There was no statistically significant difference between the preoperative and postoperative IOP at 3 months. There were no significant differences found between preoperative and post operative keratometry readings or automated refraction following orbital decompression.Conclusion:Our study did not find a significant change in IOP and refraction following orbital decompression with intraconal fat excision. A larger prospective study is required in order to evaluate the role of intraconal fat excision in reducing IOP due to it’s potential role in patients with concurrent glaucoma.

We report a 16-month-old girl referred for bilateral epiphora and sticky eyes since birth. Examination revealed a refluxible left lacrimal sac mucocele, agenesis of the left lower punctum, and agenesis of both puncta on the right side. Complete bony obstruction was noted on probing of the left nasolacrimal duct. At 4 years of age, she underwent left external dacryocystorhinostomy (DCR) with silicone intubation because of chronic dacryocystitis. Her epiphora and stickiness improved significantly in the first postoperative year, but she subsequently developed dryness of the left eye, dry mouth, and dental caries. CT and MRI scans revealed the absence of the lacrimal and salivary glands. The clinical signs and symptoms improved with plugging the left upper punctum and topical lubricants. Aplasia of the lacrimal and salivary glands may present with symptoms of congenital lacrimal obstruction, and failure to make an early diagnosis will result in inappropriate lacrimal surgery and dry eye.
