Technique and Results of Permanent Medial Tarsorrhaphy for Complex Eyelid Malposition.

PURPOSE: To evaluate the results of permanent medial tarsorrhaphy and to describe the surgical technique. METHODS: Medial tarsorrhaphy was performed on 30 eyelids with symptomatic exposure keratopathy secondary to eyelid malposition. Observational, retrospective review of preoperative and postoperative examination findings was performed. RESULTS: Average age of the cohort was 66 years (31-91). Medial tarsorrhaphy was performed to correct eyelid retraction (100%), exposure keratopathy (80%), lagophthalmos (57%), and ectropion (17%) in patients with cranial nerve VII palsy (47%), Graves eye disease (13%), eczema (7%), floppy eyelid syndrome (7%), after Mohs reconstruction (7%), orbital myositis (3%), and neurofibromatosis (3%). Seventy-three percent (73%) of patients had an average of 3 surgeries (N = 22, standard deviation = 1.12, range = 2-7) before undergoing medial tarsorrhaphy. Medial tarsorrhaphy was performed in combination with another procedure in 53% of cases. Palpebral fissure decreased postoperatively an average of 1.1 mm (N = 20; p = 0.005), inferior scleral show decreased 0.72 mm (N = 22; p = 0.03), lagophthalmos decreased 0.4 mm (N = 15; p = 0.27), and superficial punctate keratopathy improved by 61% (N = 27; p = 0.009). Ectropion completely resolved in 4 of 10 patients (40%). Seven patients (23%) required additional surgery following tarsorrhaphy an average of 8 months later (range = 2-16). In 1 patient (3%), a tarsorrhaphy opened prematurely, and 1 patient (3%) requested partial opening of the tarsorrhaphy. Average duration of follow up was 13 months (N = 30, standard deviation = 14.97, range = 0.2-45.7). CONCLUSIONS: Medial tarsorrhaphy is a safe and effective primary or salvage technique to address complex causes of eyelid retraction, lagophthalmos, ectropion, and exposure keratopathy.

Absorbable Implant Foreign Body Reaction Masquerading as Orbital Cellulitis.

Poly-DL-lactide polymer implants absorb over a period of 6 to 12 months and have been used with increasing frequency for repair of orbital fractures. The authors describe the case of a 7-year-old boy who presented with orbital inflammation 10 months following repair of a white-eyed blowout fracture with a poly-DL-lactide implant. Rapid improvement in symptoms followed initiation of oral steroids, with excellent long-term result. Clinical presentation and treatment response implicated a foreign body inflammatory reaction as the underlying etiology of symptoms. Ophthalmologists and orbital surgeons should be aware that absorbable implants can demonstrate this late idiosyncratic complication.

Endoscopic dacryocystorhinostomy following radioactive iodine thyroid ablation.

This article evaluates the efficacy of endoscopic dacryocystorhinostomy (eDCR) for nasolacrimal duct obstruction (NLDO) in patients exposed to radioactive iodine (RAI) for treatment of thyroid carcinoma. Retrospective chart review of 7 eDCR procedures was performed on 6 patients, aged 18 or older, with prior RAI treatment, who underwent eDCR between January 1, 2008 and December 31, 2013 for treatment of epiphora due to NLDO. Average time to tube removal was 159 days, and average follow-up was 341 days. One patient noted complete epiphora relief at the time of their final visit. Partial symptom relief was noted by 3 patients, and recurrent epiphora was noted by 2 patients. In complex patients with RAI-associated NLDO, eDCR may be a reasonable option for relief of epiphora. Appropriate counseling, including the risks of incomplete symptom relief and need for additional surgery, should be discussed pre-operatively with these patients.

Proprioceptive Phenomenon With Involutional Ptosis: Evidential Findings in Anophthalmic Ptosis.

PURPOSE: To determine the effect of ptosis on compensatory frontalis contraction in patients without visual input and to identify if a sensory stimulus contributes to brow elevation. METHODS: A prospective study. Clinical photographs were measured by 2 masked oculoplastic surgeons to determine brow height in 8 patients with unilateral ocular prosthesis in 3 conditions: at baseline, after a gold weight was applied to the upper eyelid inducing acute ptosis, and with the gold weight plus topical anesthetic. The measured brow height was then compared between the 3 scenarios. RESULTS: Mean brow height increased after application of the gold weight when compared with baseline, and this difference reached significance (p = 0.012). After topical anesthetic was applied, the mean brow height decreased but not back to baseline. When mean brow height during the gold weight with topical anesthesia was compared with baseline and with the gold weight only scenarios, the difference was not significant (p > 0.05). CONCLUSIONS: Frontalis contraction is observed when acute ptosis is simulated in anophthalmic patients, confirming that a contracted visual field cannot be the only stimulus for compensatory brow elevation. A sensory or proprioceptive mechanism is suggested but not confirmed by the trend of reduction in brow elevation with topical anesthesia.

The Effect of Transconjunctival Blepharoplasty on Margin Reflex Distance 2.

BACKGROUND: The objective of this study was to determine the effects of lower eyelid transconjunctival blepharoplasty (TCB) on lower eyelid position. METHODS: Transconjunctival blepharoplasty was performed alone in 15 lower eyelids without simultaneous canthoplasty or upper eyelid procedure. In this study, blepharoplasty was performed by the transconjunctival approach without removal of skin. Four eyes received TCB plus Erbium laser, two patients received TCB plus trichloroacetic acid peel (TCA), and three patients received TCB plus fat transposition. Pre-operative and post-operative margin reflex distance 1 (MRD 1) and margin reflex distance 2 (MRD 2) were compared, with MRD 1 acting as the control. RESULTS: Average time to post-operative photo was 4.6 months (1-10 months). The changes in MRD 2 and MRD 1 were compared pre- and post-operatively, and the difference reached significance by one-tailed comparison (P < 0.05). In 11/15 eyes (73 %), MRD 2 decreased post-operatively. In 6/7 eyes (86 %), lower lid scleral show was eliminated post-operatively. There were no cases of lid retraction noted. CONCLUSIONS: Transconjunctival blepharoplasty (± skin resurfacing) did not induce lid retraction but elevated the lower lid in majority of patients. Elevation of the lower lid can reduce or eliminate scleral show inferiorly, providing further cosmetic advantage. The presumed mechanism of lower lid height elevation is partial recession of the lower lid retractors during the surgical approach to the fat pockets.

Incidence of Blepharoptosis Following Intravitreal Anti-Vascular Endothelial Growth Factor Injections.

PURPOSE: To determine the incidence of blepharoptosis after intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections and compare the rates of blepharoptosis between patients injected with an eyelid speculum and those injected without a speculum. DESIGN: Retrospective cohort study. METHODS: International Classification of Diseases, Tenth Revision (ICD-10), codes were used to identify patients with exudative age-related macular degeneration (AMD) and those who developed ptosis after intravitreal injections. Patients with nonexudative AMD who did not receive intravitreal injections served as controls. The outcomes were the incidence of ptosis in the injection group compared to the noninjection group and incidence of ptosis in patients whose injections were performed with an eyelid speculum as compared to those whose injections were performed without a speculum. RESULTS: We recruited 1100 exudative AMD patients who received at least 1 intravitreal anti-VEGF injection and 2258 nonexudative AMD patients who had not received an injection. In the injection group, 18 of 1100 patients (1.6%) developed ptosis, compared with 52 of 2258 patients (2.3%) in the noninjection group (P = .25). Within the injection group, ptosis was mostly bilateral, diagnosed on average 22.4 months after the initial injection, and after more than a 1-year injection-free period. Eleven of 537 patients (2.0%) injected without a speculum developed ptosis, compared with 8 of 444 patients (1.8%) injected with a speculum (P = .82). CONCLUSIONS: No statistically significant differences in incidence rates of ptosis were observed. In this analysis, neither intravitreal anti-VEGF injections nor speculum use during injections appears to increase the risk of ptosis.

Evaluation of the canalicular entrance into the lacrimal sac: an anatomical study.

PURPOSE: The purpose of this study was to investigate the prevalence of a common canalicular entrance in the lacrimal sac and to investigate the anatomy of the canalicular/lacrimal sac junction with direct visualization using a novel cadaveric dissection technique. METHODS: Preserved cadavers were dissected to allow direct visualization of the canalicular entrance(s) to the lumen of the lacrimal sac. The prevalence of a common canaliculus and the anatomical variations of the canalicular/lacrimal sac mucosal fold of tissue were recorded. RESULTS: One hundred twenty-four lacrimal systems (95 cadavers; 43 female, 52 male) were included in the study analysis. Overall, 123 lacrimal systems demonstrated a common canaliculus entering the lacrimal sac. Only one demonstrated 2 separate orifices (right orbit; male) in the sac (0.08%; 95% confidence interval, 0.1%-4.4%). Seventy-four lacrimal systems had some variation of a canalicular/lacrimal sac mucosal fold (59.7%). The remaining 50 (40.3%) had no visible canalicular/lacrimal sac mucosal fold. CONCLUSIONS: This study provides direct anatomical evidence that the prevalence of separate canalicular orifices in the lacrimal sac is lower than previously reported (<1%). Additionally, the presence of a valve-like structure at the canalicular/lacrimal sac junction is common. These observations can potentially play a role in evaluating and treating lacrimal system pathology.

Periocular Reconstruction.

Options for periorbital reconstruction include primary wound closure, local flaps, regional/distant flaps, or full-thickness skin grafts. Optimal aesthetic and functional outcomes are achieved by assessing regional contours, skin type, and facial aesthetic units. Like tissue should replace like tissue; for example, skin with skin, tarsus with tarsus (or equivalent material, eg, hard palate, ear cartilage, or autologous substitute), and conjunctiva with mucous membrane or like substitute (buccal mucous membrane, amniotic membrane). Patient characteristics including wound care needs, transportation needs, smoking status, and history of radiation can influence the reconstruction plan. Techniques most commonly used in our practice are reviewed.

Comparison of the extrusion rate of Crawford tubes.

AIM: To compare the outcomes of dacryocystorhinostomy (DCR) using traditional Crawford tubes (TCT) and Crawford tubes with suture (CTS) in the lumen. METHODS: Retrospective case series consisting of patients who underwent DCR between 2008 and 2013. RESULTS: A total of 61 DCRs were performed on 50 patients. Patients who underwent DCR using CTS had higher rates of prolapse compared to the TCT group (50% vs 9.4%; P=0.003). Stent removal occurred earlier in patients who received CTS (3.3mo vs 5.1mo; P=0.004). Success rates were equivalent between the two groups (75% vs 81.1%; P=0.684). CONCLUSION: CTS in the lumen increases the risk of prolapse, prompting earlier tube removal in patients following DCR for nasolacrimal duct obstruction (NLDO). Earlier removal of tubes does not appear to significantly decrease success rates.

Evaluation and treatment of perioperative corneal abrasions.

Purpose. To evaluate perioperative risk factors for corneal abrasion (CA) and to determine current care for perioperative CA in a tertiary care setting. Methods. Hospital-based, cross-sectional study. In Operating Room and Post-Anesthesia Care Units patients, a comparison of cases and controls was evaluated to elucidate risk factors, time to treatment, and most common treatments prescribed for corneal abrasions. Results. 86 cases of corneal abrasion and 89 controls were identified from the 78,542 surgical procedures performed over 2 years. Statistically significant risk factors were age (P = 0.0037), general anesthesia (P < 0.001), greater average estimated blood loss (P < 0.001), eyes taped during surgery (P < 0.001), prone position (P < 0.001), trendelenburg position (P < 0.001), and supplemental oxygen en route to and in the Post-Anesthesia Care Units (P < 0.001). Average time to complaint was 129 minutes. 94% of cases had an inpatient ophthalmology consult, with an average time to consult of 164 minutes. The most common treatment was artificial tears alone (40%), followed by combination treatment of antibiotic ointment and artificial tears (35.3%). Conclusions. Trendelenburg positioning is a novel risk factor for CA. Diagnosis and treatment of perioperative corneal abrasions by an ophthalmologist typically require three hours in the tertiary care setting.
