Superior Rectus Recession

Introduction

Muscle recession is a type of strabismus surgical procedure that aims to weaken an extraocular muscle by adjusting its insertion posteriorly closer to its origin. The patient is a 14-year-old with dissociated vertical deviation, which can be corrected with recession of the superior rectus muscle.

Methods

A conjunctival incision is made in the fornix. Tenon’s capsule is dissected to expose the superior rectus muscle. The superior rectus muscle is isolated using a Stevens tenotomy hook followed by a Jameson muscle hook. After the remaining Tenon’s attachments are cleared, the muscle is secured at both poles with a double-armed 6-0 VicrylTM suture and double-locking bites. The muscle is then disinserted from the sclera with Manson-Aebli scissors. A caliper is used to mark the predetermined distance of muscle reinsertion. Next, the muscle is reattached to the sclera with partial thickness bites and then tied down to its new location. The conjunctival incision is closed with 6-0 plain gut sutures.

Results

No complications arose during the procedure. Postoperatively, the patient had subconjunctival hemorrhage, injection, and pain that decreased over the following week. Neomycin-polymyxin-dexamethasone drops were applied daily to prevent infection and inflammation. At the three-month follow up, the redness had resolved. The dissociated vertical deviation had improved.

Conclusion

Superior rectus recession is a safe procedure that can effectively treat vertical strabismus.

Lateral Rectus Plication

Introduction

Muscle plication is a type of strabismus surgery that aims to tighten an extraocular muscle by partially folding the muscle under or over itself without disinsertion. The patient is a 14-year-old with alternating esotropia, who previously had a medial rectus recession. Therefore, she underwent plication of the lateral rectus muscle for this procedure.

Methods

A conjunctival incision is made in the fornix. Tenon’s capsule is dissected to expose the lateral rectus muscle. The lateral rectus muscle is isolated using a Stevens tenotomy hook followed by a Jameson muscle hook. A Stevens tenotomy hook is used to sweep around the muscle to confirm the location of the muscle pole. A caliper is used to mark the predetermined amount of plication, starting at the muscle insertion and marking further posteriorly on the muscle. The muscle is then secured at the location marked by the caliper with a double-armed 6-0 VicrylTM suture with a central bite and double-locking bites at each pole of the muscle. Plication is achieved by bringing the muscle anteriorly and attaching it to the sclera adjacent to the muscle insertion with half-scleral depth bites in crossed-swords fashion. The muscle is tied down to its new location and 6-0 plain gut sutures are used to close the conjunctival incision.

Results

No complications arose during the procedure. Postoperatively, the patient had subconjunctival hemorrhage, injection, and pain that decreased over the following week. Neomycin-polymyxin-dexamethasone drops were applied daily to prevent infection and inflammation. At the three-month follow up, the redness had resolved. The alternating esotropia had improved.

Conclusion

Lateral rectus plication is a safe procedure that can effectively treat esotropia.

Cataract Phacoemulsification and Intraocular Lens Implantation in a Small Pupil Case

Intro
Phacoemulsification and intraocular lens implantation is the gold standard procedure for removing cataracts in developed countries. The patient is an elderly adult who underwent the surgery to alleviate visual impairment from a significant age-related mixed cataract. Before the surgery, his visual acuity in the operative eye was 20/60.

Methods
This video highlights the steps of cataract phacoemulsification and intraocular lens implantation in a small pupil case, including paracentesis, epinephrine-lidocaine (epi-Shugarcaine) injection for extra dilation and anesthesia, viscoelastic injection into the anterior chamber, capsulorrhexis, hydrodissection, phacoemulsification featuring a divide and conquer technique, cortical irrigation and aspiration, intraocular lens insertion, and wound sealing by hydration.

Results
No complications arose during the procedure. At the two-week postoperative follow-up, the patient’s visual acuity in the operative eye was 20/30. He denied any pain or discomfort. The visual acuity at four weeks was 20/20. The patient was pleased with results of the surgery.

Conclusion
Phacoemulsification and intraocular lens implantation is a safe and effective surgery for the management of cataracts. In the setting of a small pupil, intracameral epinephrine-lidocaine mix (epi-Shugarcaine) can be administered for extra dilation.

Chalazion Incision and Curettage

Intro

A chalazion is a lipogranulomatous inflammation of a meibomian gland in the eyelid that presents as a painless eyelid nodule or swelling. This pediatric patient presented with a chalazion that caused symptoms of eye irritation. The lesion had persisted for many months without improvement in response to warm compresses and eyelid scrubs with baby shampoo. Therefore, she underwent chalazion incision and curettage under sedation.

Methods

This video highlights the steps of chalazion incision and curettage. With a chalazion clamp tightened over the lesion, the eyelid is everted and an incision is made into the tarsus. A curette is used to scrape the walls of the cyst to remove the chalazion contents. At the conclusion of the procedure, the clamp is removed and pressure is applied to the area of the lesion for hemostasis.

Conclusion

Incision and curettage is a safe, relatively quick, and effective procedure for the management of persistent chalazia.
