Urrets-Zavalia syndrome after implantable collamer lens implantation

Mahziba Rahman Chowdhury — 2026-01-29

Urrets-Zavalia syndrome (UZS), characterized by iris atrophy and a fixed, dilated pupil, is a rare postoperative complication that can occur after ocular surgery. We outline the case of a 19-year-old male patient in good health who was treated with an implantable collamer lens for extreme myopia and astigmatism in both eyes. During surgery, the patient’s left eye had a fixed, mid-dilated pupil, and on the first postoperative day, his intraocular pressure (IOP) was elevated. With medical intervention, the high IOP was reduced within three days. Pilocarpine (2%) eye drops proved ineffective to constrict the pupil in the left eye. Up to one year of follow-up period, the pupil remained at a mid-dilated state and was unresponsive to both light and accommodative stimuli, and the best corrected vision was 6/9 in the right eye and 6/18 in the left eye. The patient has been diagnosed with UZS.

Outcome of lateral tarsal strip in managing the paralytic eyelid eversion

Riffat Rashid — 2026-03-03

Background: Paralytic eyelid eversion (ectropion) is prevalent in admitted individuals with ineffectiveness of the
cranial nerve 7, brain tumor, and leprosy. Neurogenic ectropion is an unusual eyelid problem due to impairment of
the 7th cranial nerve, which can cause multiple difficulties due to inadequate corneal protection.
Objective: To describe the surgical efficacy of the lateral tarsal strip (LTS) technique in managing the paralytic
eyelid eversion or ectropion.
Methods: This study was conducted prospectively at a third-level eye care center in Bangladesh for 3 years
commencing from 2019, involving 26 patients. The included patients involved the paralytic eversion of the inferior
lid who underwent LTS surgery. The principal findings, like surgical outcome, contouring of the lid, complications,
follow-up time, and recurrence, were recorded. All the study subjects were examined within 14 days, and the
standard follow-up period was 12 months.
Results: The full number of studied cases was 26. In this research, males represented 73%, while females
accounted for 27%. The average age was 57.8 14.9 years and ranged from 24 to 72. In operated cases, the
right eyes were 15 cases (57.70%), and the left eyes were 11 cases (42.30%). The final better outcome of surgical
modification was 93%. Twenty-four eyelids had an outstandin appearance after surgery. Mild complication includes
postoperative lid swelling in seven eyelids, which was resolved within 7 days. Just two patients had mild lid eversion
at the end of the follow-up schedule.
Conclusion: LTS is a simple, easy-to-maintain, and potent technique to correct paralytic eyelid eversion. It
is essential to fixate the LTS above the lateral canthus to minimize new occurrence, and achieve the desired
clinical outcome.

The impact of cataract surgery on normal ocular surface: an experience from a tertiary center of southern region of Bangladesh

Md. Shahriar Alam — 2026-02-15

Background: Ocular surface homeostasis and tear film stability can be compromised after cataract surgery, leading to dry eye disease (DED), whose incidence may vary widely and is often ignored as-a knowledge gap in Bangladesh.

Objective: To determine the frequency, severity, and predictors of tear film instability (DED) following age-related cataract surgery in a tertiary hospital in Bangladesh.

Methods: A prospective observational study was conducted at Chittagong Medical College Hospital (CMCH) from January 2022 to June 2023 among 113 patients aged ≥40 years undergoing small-incision cataract surgery or phacoemulsification. Patients with pre-existing DED or ocular surface disease were excluded. Tear Film Break-Up Time (TBUT) and Schirmer’s Test-1 (ST-1) were assessed before surgery and at 1 week, 1 month, and 3 months after surgery. Statistical analysis was performed using SPSS v25.0.

Results: Postoperative tear film instability peaked on day 7 (62.8%), declined to 39.8% on day 30, and was 12.4% on day 90 (p < 0.001). Mean TBUT and ST-1 values decreased significantly postoperatively but remained below baseline at 3 months. Incision length (p = 0.048) and longer microscope light exposure (p = 0.022) were independent predictors of tear film stability, while age, sex, surgical type, and cumulative dissipated energy (CDE) were not.

Conclusion: Cataract surgery causes a significant, but largely transient, reduction in tear film stability leading to DED, which peaks in the first postoperative week, with partial recovery by 3 months. Minimizing incision size and light exposure may reduce risk.
