How to reduce conjunctival cyst formation after strabismus surgery?

Purpose: To determine our rate of conjunctival cyst developing after strabismus surgery and to minimize its formation.

Materials And Methods: The data of 4026 eyes of 2662 patients were included in our retrospective analysis of, those that underwent strabismus surgery at the Beyoğlu Eye Training and Research Hospital Strabismus Unit between 2015 and 2021. Clinical characteristics and follow-up data of patients were recorded together with age, sex, and operation type.

Retinal and choroidal microvasculature is altered after strabismus surgery.

Purpose: To evaluate the retinal and choroidal microvasculature after strabismus surgery using swept-source optical coherence tomography angiography (OCTA).

Methods: Thirty-three eyes of 33 patients who underwent horizontal rectus surgery for strabismus were included in this retrospective study. The unoperated fellow eyes were used as the control group.

Treatment of convergence insufficiency type intermittent exotropia with bupivacaine injection to the medial rectus combined with lateral rectus recession.

Purpose: To evaluate the outcomes of combined bupivacaine HCL (BPX) injection in the medial rectus (MR) muscle with recession of the lateral rectus muscle in the treatment of convergence insufficiency-type intermittent exotropia (CI-IXT).

Methods: The medical records of patients who underwent combined injection-recession treatment from January 2019 to January 2020 for CI-IXT were reviewed retrospectively along with a group of age-matched controls with IXT without CI who underwent only unilateral LR recession during the same period. The following data were extracted from the record: age at surgery, average follow-up period, angle of deviation at distance and near and the difference between them before and after surgical procedure, correction of near and distance deviations, and recession dosage.

Brown Syndrome: Features and Long-term Results of Management.

Objectives: The goal of this study was to evaluate surgical techniques and outcomes in patients with Brown's syndrome.

Methods: A retrospective review was conducted of patients who underwent surgery of the superior oblique (SO) muscle between 2003 and 2011 at a referral center.

Results: In all, 190 patients (111 female and 79 male) with an age range of 4-50 years were included in the study.

Muscle belly union surgery with or without medial rectus recession for the treatment of high myopic strabismus fixus.

Purpose: To evaluate the results of surgery involving the union of the superior rectus muscle and the lateral rectus muscle with or without medial rectus recession (MRc) for the treatment of high myopic strabismus fixus over a 20-year period.

Methods: The medical records of patients who underwent muscle belly union for the treatment of high myopic strabismus fixus were reviewed retrospectively. Patients were classified according to the timing of MRc.
