Temporary Medial Upper Eyelid Lagophthalmos after External Dacryocystorhinostomy.

Background. Report of three cases of medial upper eyelid lagophthalmos as complication of external dacryocystorhinostomy. History and Signs. Shortly after dacryocystorhinostomy (skin incision on the side of the nose), three of ten consecutive patients (28 ± 4 years; mean ± standard deviation), presented with an ipsilateral lagophthalmos of 4 ± 1 mm in voluntary eyelid closure and 6 ± 1 mm in spontaneous blink. The lagophthalmos was due to a selective paresis of the medial part of the orbicularis oculi muscle of the upper eyelid. Patient 1 complained bitterly of dry eye symptoms and of her lagophthalmos. Patient 2 had mild symptoms but became very concerned after peers made her aware of her asymmetric blink. Patient 3 was asymptomatic and did not notice anything particular. Therapy and Outcome. Lagophthalmos resolved spontaneously within three months after surgery, first by improvement of voluntary eyelid closure and then of spontaneous blinking. Conclusions. Temporary lagophthalmos can occur as a complication of external dacryocystorhinostomy, most likely due to damage of the (only recently described) superficial buccal and/or zygomatic branches of the facial nerve that run upward to cross over the medial ligament and innervate the medial part of the orbicularis oculi muscle.

Excision and Redraping Skin and Orbicularis Oculi Muscle Separately during Transcutaneous Lower Eyelid Blepharoplasty.

BACKGROUND: The purpose of this study was to report a transcutaneous lower eyelid blepharoplasty procedure where different amounts of skin and orbicularis oculi muscle are excised and where skin and muscle are redraped (tightened) separately. PATIENTS AND METHODS: A retrospective non-consecutive small case-series of patients undergoing lower eyelid blepharoplasty is described. In a nutshell, during this procedure a skin flap was fashioned (caudal to the sub-ciliary pre-tarsal excess of skin to be excised), some pre-septal orbicularis oculi muscle fibers were excised (in regard of the skin flap), muscle and then skin were redraped, separately. In addition to these surgical steps conducted on each patient, when required, orbital fat prolapse was reduced, orbital retaining ligament was detached, and/or a canthopexie/plasty was performed. Assessment of surgical outcome was made by providing, for comparison, pictures taken before and after the procedure. RESULTS: No major intra- or postoperative complications were recorded and overall postoperative outcome was judged satisfactory by both surgeons and patients. CONCLUSIONS: In contrast to a conventional skin-muscle lower blepharoplasty approach where, in a block, pre-tarsal skin and muscle are excised and then pre-septal skin and muscle are redraped, the technique described in the present paper allows us to excise different amounts of skin and orbicularis muscle and to redrape them separately. Among several potential advantages, this approach preserves pre-tarsal orbicularis muscle function, allows us to apply more tension on the redraped muscle and less on the redraped skin, and avoids redraping of a relatively thick per-septal orbicularis oculi muscle over the tarsus (like it is in the case of a conventional skin-muscle technique).

Treatment of epiphora in connection with endolacrimal surgery using trephines: new and overview data.

BACKGROUND: To provide new and to summarize published data on endolacrimal surgery with Piffaretti's trephines, in particular in patients having patent lacrimal drainage system (syringing) and epiphora resistant to medical treatments. PATIENTS AND METHODS: From two tertiary referral centers (Basel/Switzerland; Belo Horizonte/Brazil), 126 patients undergoing endolacrimal surgery with Piffaretti's trephines, combined, when clinically indicated, with other procedures known to improve epiphora (canthoplasty/pexie and/or conjunctivochalasisplasty). RESULTS: I) A study (Basel) in 17 patients showed one-year after surgery marked epiphora symptoms' improvement in 88% (15/17) of patients, 65% (11/17) being symptom-free. II) Unpublished data (Belo Horizonte) in 42 patients found 81% (34/42) symptom-free six-months after surgery. Dacryoscintigraphy illustrated postoperative tears' clearance improvement. III) Unpublished data (Belo Horizonte) in 45 patients solely undergoing endolacrimal surgery for complete ductal obstruction found symptom-free, six-months after surgery, 27% (8/30) of patients with preoperatively enlarged lacrimal sac and 80% (12/15) with none-enlarged sac (p < 0.01, Fisher's test). IV) A study (Basel) in 22 epiphora patients reported no correlation (p = 0.62, rho -0.11, Spearman) between preoperative basal Schirmer's test II (oxybuprocain-HCL 0.4%) values and one-year surgical outcome. Patients with preoperative Schirmer's test's values ≤ or > 6 mm had similar mean postoperative symptoms' improvement (82 ± 30%, n = 11 vs. 76 ± 34%, n = 11, p = 0.97, Mann-Whitney). CONCLUSIONS: Endolacrimal surgery with Piffaretti's trephines, sometimes combined, when clinically indicated, with other procedures also known to ameliorate epiphora, can in particular improve (different conditions, surgeons, centers) epiphora's symptoms resistant to medical treatments in patients with patent lacrimal drainage system, and this apparently, even when pre-operative basal Schirmer-test values are low. By enlarged lacrimal sac, outcome is poor.

Delayed reconstruction after eyelid tumor excision.

BACKGROUND: The aim of this study is to report the feasibility of one to two weeks delayed reconstruction after eyelid tumor excision. PATIENTS AND METHODS: A retrospective case-series study was designed. Fourteen consecutive outpatients referred to a tertiary referral eye center for eyelid tumor management were enrolled. The intervention imvolved eyelid tumor excision (with four millimeters surrounding clinically tumor-free tissue), compressive patching of the excised area until reconstruction (with or without a therapeutic contact lens), extensive histological work-up to assess histological tumor clearance, and reconstruction one week after excision (in a couple of patients after two weeks when further excision was necessary to achieve tumor clearance). Excision and closure were performed by a single external trained oculoplastic surgeon (IOH) with a day per week (Fridays) operating slot. As outcome we assessed whether such an approach has led before, during, or after eyelid reconstruction to unusual major adverse events (follow-up time: 18 - 36 months). RESULTS: Delaying up to one week, in some cases even two weeks, reconstruction after eyelid tumor excision was not associated with any unusual major adverse events before, during, or after surgery. CONCLUSIONS: When necessary, after eyelid tumor excision, it is possible to delay for one week or even for two weeks reconstruction, apparently without experiencing major unusual adverse events.

Mucosal excision instead of fashioning nasolacrimal mucosae flaps during external dacryocystorhinostomy: a pilot study.

BACKGROUND: To report results of a simplified external dacryocytorhinostomy procedure in which nasal and lacrimal sac mucosal flaps are simply removed instead of being sutured together. DESIGN: Retrospective non-comparative case-series study. PARTICIPANTS: Fourteen consecutive outpatients patients undergoing external dacryocytorhinostomy. INTERVENTION: Modified and simplified transcutaneous external dacryocytorhinostomy where basically the lacrimal sac and the nasal mucosae are widely excised in front of DCR's osteotomy instead of being used to fashion nasolacrimal flaps. OUTCOME: Assessment of dacryocytorhinostomy anatomical patency by syringing and patient's self-perception of epiphora symptoms improvement about twelve weeks and one year after surgery, as well as patient's report of ocular air-reflux during Valsalva maneuver a year after surgery. RESULTS: Syringing showed anatomic patency in 93 % and 92 % of patients twelve weeks (mean ± SD: 12 weeks ± 6 weeks) and one year (15 months ± 3 months) after surgery, respectively. One year after surgery, 62 % of patients reported ocular air-reflux. Twelve weeks and one year after surgery, mean symptom improvement was 82 % ± 17 % and 79 % ± 29 %, respectively. Furthermore, 79 % and 85 % of patients reported a postoperative improvement of their symptoms greater or equal to 80 % after twelve weeks and one year, respectively. CONCLUSIONS: Removing lacrimal sac and nasal mucosae in front of the osteotomy did not appear to have a major negative impact on the outcome of the external dacryocytorhinostomy. The findings of this pilot study need to be confirmed by a larger prospective trial.

Improvement of chronic epiphora symptoms after surgery in patients with different preoperative schirmer-test values.

BACKGROUND: To compare improvement of epiphora symptoms after surgery between patients who had different preoperative basal Schirmer test values. DESIGN: Retrospective comparative case-series study. PARTICIPANTS: Twenty-two consecutive patients (one eye/patient) undergoing surgery for chronic epiphora symptoms resistant to ≥ 6 months of medical treatments (who incidentally had a preoperative basal [oxybuprocain-HCL 0.4 %] Schirmer-test and a postoperative one-year follow-up) were ranked according to their preoperative basal Schirmer test values and divided into two groups of equal size: group I, patients with lower (0 to 6 mm) and group II, patients with higher (7 to 25 mm) Schirmer test values. INTERVENTION: Combination of Piffaretti's endocanlicular endoscopic lacrimal drainage (22 patients), lacrimal intubation (8 patients), lacrimal punctoplasty (22 patients), lateral canthoplasty (18 patients), and/or conjunctivochalasis (8 patients) surgical procedures. OUTCOME: Subjective self-perceptions of improvement of their epiphora symptoms was made by the patients one-year after surgery. RESULTS: While between groups I and II mean (± SD) preoperative basal Schirmer test values significantly differed (4 ± 3 mm/ 5 min vs. 10 ± 6 mm/ 5 min, p ≤ 0.001, Mann-Whitney rank sum test), the mean postoperative improvement of epiphora symptoms did not (82 ± 30 % vs. 76 ± 34 %, p = 0.92) and no significant (rho = -0.11, p = 0.62, Spearman rank correlation coefficient) correlation between Schirmer test values and symptoms improvement was found. In both groups > 70 % of patients reported ≥ 70 % (satisfactory) postoperative improvement. CONCLUSIONS: In the present study, patients who had different preoperative basal Schirmer test values reported having very similar epiphora symptoms improvement one-year after surgery.

Pathophysiology of intraocular pressure increase and glaucoma prevalence in thyroid eye disease: a mini-review.

BACKGROUND: The aim of this study was to assess the pathophysiological mechanisms leading to intraocular pressure (IOP) increase and to review the prevalence of glaucoma in thyroid eye disease (TED), an autoimmune reaction affecting extra-ocular muscles and intra-orbital content in thyrotoxicosis (Grave's disease, hyperthyroidism). MATERIAL AND METHODS: We applied the modified Friedenswald's and Goldmann's equations to explain the mechanisms by which IOP increases in TED and gave a brief review of the literature. RESULTS: In TED, Friedenswald's equation explains the ultra-short term IOP increase observed when eyes deviate from their primary gaze position (eyeball compression by enlarged and infiltrated extra-ocular muscles). Goldmann's equation explains the long-term IOP increase seen in TED (episcleral venous pressure elevation secondary to intraorbital content and pressure increase). Most studies did not find a significant increase in glaucoma prevalence in patients with TED. CONCLUSION: In TED, glaucoma prevalence does not seem to be significantly increased and, from a pathophysiological standpoint, the long-term IOP increase is essentially due to episcleral venous pressure elevation.

Large upper eyelid full-thickness defects reconstructed only with an anterior lamella.

BACKGROUND: The purpose of this study is to report a surgical procedure that only uses anterior lamella structures (muscle and skin) to reconstruct large upper eyelid full-thickness total defects. PATIENTS AND METHODS: The study design is a non-comparative retrospective interventional small case series. Three patients with upper eyelid full-thickness (anterior and posterior lamellae) total-defect (horizontal extent: > 3/4 length, vertical extent: > 15 mm) after tumor excision (basal cell, squamous cell, or Merkel's cell carcinoma). As intervention an eyelid reconstruction using only a rotation/advancement muscular-skin flap was used. The outcome was postoperatively an upper eyelid anatomic cosmetic-appearance and lid-closure function. RESULTS: Good anatomic cosmetic-appearance and lid-closure function were achieved soon after surgery. No remarkable ocular as well as extra-ocular side effects or complications were noted. CONCLUSIONS: In a single-stage procedure it appears possible to repair upper eyelid full-thickness total defects by reconstructing only the anterior lamella. With this procedure there is no need to reconstruct the posterior lamella and/or to use tissue from other eyelids or parts of the body.

Feasibility of not having a postoperative control at day-1 after outpatient oculoplastic surgical procedures.

BACKGROUND: After outpatient oculoplastic surgical procedures, to report the feasibility of a policy of planning the first post-operative control not at one day after surgery but at the time of suture removal or lacrimal drainage system irrigation. PATIENTS AND METHODS: A retrospective case-series chart review analysis in a tertiary referral center of hundred and five consecutive outpatients was performed. Surgical procedures: eyelid (75/105), transpunctal endoscopic lacrimal drainage (11/105), both eyelid and transpunctal endoscopic lacrimal drainage (15/105), orbita soft tissue (4/105). MAIN OUTCOME: number of patients who had a first post-operative control for a different purpose than the one planned by the policy and whether it led to additional interventions. RESULTS: Out of 105 patients, 95 had their first control 12 +/- 4 days (mean +/- SD) after surgery according to the established policy. In 10 patients the first control occurred earlier (3 +/- 1 days) without leading to additional medico-surgical interventions. CONCLUSION: After outpatient oculoplastic surgical procedures, it is possible, with apparently no major consequences, to plan the first post-operative control not on the first day after surgery but later at time of suture removal or lacrimal drainage system irrigation.

Eyelid sebaceous gland carcinoma in a young Caucasian man.

BACKGROUND: Eyelid sebaceous gland carcinoma is rarely observed in young Caucasian men. HISTORY AND SIGNS: A 28-year-old man was referred for a recurring chalazion of the eyelid that had been operated four times in the past two years. The chalazion-like lesion of the external third of the upper left eyelid was associated with a cystic lesion. Cytology of the fluid in the cyst and histology of the lesion were compatible with a sebaceous cell carcinoma. Magnetic resonance imaging revealed that the cystic lesion associated with the eyelid tumour was extending into the orbit. THERAPY AND OUTCOME: According to current clinical practice and experience, to increase the chance of survival of the patient, an orbital exenteration was conducted to remove the sebaceous cell carcinoma in total. CONCLUSIONS: Although rare, one should be aware that an eyelid sebaceous cell carcinoma can occur in a young Caucasian man and this diagnosis should be evoked in case of a recurrent chalazion.

Unexpected bleeding following eyelid tumor resection leading to the rare diagnosis of acquired haemophilia.

BACKGROUND: Our goal is to report for the first time in the literature a case of uncontrolled bleeding after an oculoplastic surgical procedure leading to the diagnosis of acquired haemophilia. HISTORY AND SIGNS: An 82-year-old patient underwent tumor excision and reconstruction of his right lower eyelid. On the same day, uncontrolled bleeding occurred that resisted optimal blood pressure control, external compression, surgical haemostasis and wound revision. Usual coagulation screening tests were normal, except for a slightly prolonged activated partial thromboplastin time. THERAPY AND OUTCOME: Extensive coagulation check was performed, which showed a severely reduced factor VIII due to the presence of an inhibitor. The bleeding was immediately stopped after administration of recombinant factor VIIa. After healing of the wound, factor VIIa treatment was replaced by immunosuppressive therapy. The factor VIII inhibitor became unmeasurable and remained so for three months after stopping the immunosuppressive therapy. CONCLUSIONS: Ophthalmologists confronted with unexpected uncontrolled bleeding should think about the possibility of blood dyscrasia, in particular acquired haemophilia.

A surgical approach to treat chronic epiphora and/or muculopurulent discharge in patients with permeable lacrimal drainage system.

BACKGROUND: This study reports the one-year success rate of a new surgical approach to treat symptoms of chronic epiphora and/or mucopurulent discharge refractive to at least six months of medical treatment in patients with permeable lacrimal drainage system (irrigation test). DESIGN: retrospective chart review analysis. PARTICIPANTS: seventeen consecutive patients referred from a private praxis to an eye clinic to treat, by surgery, symptoms of either chronic epiphora (8/17), mucopurulent discharge (7/17), or both (2/17). INTERVENTION: Piffaretti's non-laser transpunctal endoscopic diagnostic/surgical lacrimal drainage procedure (17/17), lacrimal punctoplasty (16/17), conjunctivochalasisplasty (5/17), lateral canthoplasty (1/17), and/or both conjunctivochalasisplasty and lateral canthoplasty (3/17). In the majority of these patients (13/17) partial obstructions within the lacrimal canaliculus (3/17), the ductus nasolacrimalis (7/17), or both (3/17) were observed endoscopically and removed with Piffaretti's lacrimal trephines. MAIN OUTCOME MEASURES: patient's self-assessment of symptom improvement one year after surgery. RESULTS: One year after surgery, 88 % (15/18) of patients had a marked improvement of their symptoms, 64 % (11/17) of them even reporting as being symptom free. When conducted (14/17), irrigation always revealed a permeable lacrimal system (test not performed in a lost-to-follow-up and in two symptom-free patients). CONCLUSIONS: Surgery can be an alternative therapeutic option for patients who have a permeable lacrimal drainage system and suffer from chronic epiphora and/or mucopurulent discharge that do not respond to conventional conservative medical therapies.

Superficial conjunctiva cauterization to reduce moderate conjunctivochalasis.

AIM: We report here a simple surgical approach to reduce moderate conjunctivochalasis. PATIENTS AND METHODS: A non-comparative prospective interventional case series study of fifteen consecutive patients with moderate conjunctivochalasis was carried out. On the inferior bulbar conjunctiva 10 to 20 superficial burns were performed with an electrical bipolar cauter to reduce moderate conjunctivochalasis. Before and around a mean time of six months after surgery digital photographs of the conjunctivochalasis were taken at the slit lamp. The maximal height of the conjunctivochalasis above the lower eyelid margin measured before surgery was compared with the height of the conjunctivochalasis measured after surgery around the same location (one eye per patient). RESULTS: In each patient, gentle and superficial cauterization induced contraction of the bulbar conjunctiva and reduction of the conjunctivochalasis. No complications were noted during or after the procedure. Mean (+/- SD) maximal conjunctivochalasis height above the lower eyelid margin was higher before (2.3 +/- 0.9 mm) than after surgery (0.8 +/- 0.6 mm). Preoperative values of conjunctivochalasis height were significantly (p < 0.001) different from the postoperative ones (Wilcoxon rank signed test). CONCLUSIONS: Gentle superficial cauterization of the inferior bulbar conjunctiva can induced significant reduction of a moderate conjunctivochalasis.

Intraocular pressure changes in the contralateral eye after trabeculectomy with mitomycin C.

AIM: To assess intraocular pressure (IOP) changes of the contralateral eyes of eyes undergoing trabeculectomy with mitomycin C (MMC). METHODS: Non-comparative retrospective study of 24 consecutive patients who underwent trabeculectomy with MMC that led to more than 45% reduction in IOP. In the contralateral eyes, IOP before surgery was compared with IOP 1 day and 1 month after surgery. 11 fellow eyes were under topical hypotensive therapy while 13 contralateral eyes were not (12 contralateral eyes had previous filtering surgery and one had normal tension glaucoma). No patients had systemic ocular hypotensive therapy. RESULTS: Mean IOP in all contralateral eyes decreased from 15.5 (SD 5.5) mm Hg to 12.5 (3.8) mm Hg (p<0.01), and 13.0 (4.7) mm Hg (p<0.001) 1 day and 1 month after surgery, respectively. In the 11 fellow eyes under topical ocular hypotensive therapy mean IOP was reduced from 19.5 (4.0) mm Hg to 13.5 (2.2) mm Hg (p<0.01), and 16.5 (2.8) mm Hg (p<0.05) 1 day and 1 month after surgery, respectively. In the 13 fellow eyes not under topical ocular hypotensive therapy mean IOP was reduced from 12.1 (4.2) mm Hg to 11.6 (4.7) mm Hg (p not significant) and 9.8 (3.8) mm Hg (p0.01) 1 day and 1 month after surgery, respectively. CONCLUSIONS: In the present population, a month after trabeculectomy, mean IOP in the contralateral eyes decreased independently of whether these contralateral eyes were undergoing topical ocular hypotensive therapy or not.

[Etiology of eyelid edema]. / Häufigste Ursachen des Lidödems in der Allgemeinpraxis.

Lidedema can be a common symptom of diseases of the orbital part of the face. One can differentiate lidedema in two groups, those that are related to an inflammation and those that are not related to an inflammation. Lidedema of the eyelid can also be secondary to a systemic disease. There is also another group that is common in the ageing population that consists of blepharochalasis and dermatochalasis where the skin becomes loose with the years and forms redundant folds.

Influence of non-penetrating glaucoma surgery on aqueous outflow facility in isolated porcine eyes.

PURPOSE: To investigate, in vitro, the influence of non-penetrating glaucoma surgery (NPGS) and the influence of tightly suturing the superficial scleral flap on the aqueous outflow facility of isolated porcine eyes. MATERIALS AND METHODS: The anterior chambers of 12 enucleated porcine cadaver eyes were cannulated and perfused. NPGS was performed by the same surgeon. The overall ocular aqueous outflow facilities were assessed before and after the surgical interventions of NPGS, as well as after scleral flap closure. RESULTS: The mean (SD) aqueous outflow facility, which was 0.164 (0.014) microl/min/mm Hg before surgery, increased significantly after NPGS to 1.584 (0.217) microl/min/mm Hg, p<0.001. When the superficial flap was closed, the aqueous outflow facility significantly decreased (0.754 (0.107) microl/min/mm Hg, p<0.001) but remained significantly higher than preoperatively (p<0.01). After suturing the superficial flap, the overall resistance increased to 1.625 (0.210) microl/min/mm Hg. The difference in the resistance to outflow before and after flap closure was 0.848 (0.169) microl/min/mm Hg. CONCLUSION: After NPGS suturing the scleral flap can modulate aqueous outflow resistance. The experimental set up described might provide an efficient model for the technical training of glaucoma surgeries.

Free autologous buccal mucosal graft transplantation to treat ocular complications after toxic epidermal necrolysis: case report.

BACKGROUND: Toxic epidermal necrolysis (TEN) can lead to ocular surface scarring associated with pain, dry eye symptoms, and decreased visual acuity that often are difficult to treat. HISTORY AND SIGNS: A 34-year-old woman was referred to our department two-years after TEN induced by lamotrigin (lamictal(R)). She was complaining of severe visual acuity loss, pain, and dry eye symptoms. Visual acuity was reduced to light perception in the right eye (RE) and to 0.2 in left eye (LE). Basal Schirmer test was 2 mm in RE and 3 mm in LE. With or without therapeutic contact lenses, the patient was experiencing severe discomfort requiring tear supplementation up to 50 - 80 times/day in both eyes. THERAPY AND OUTCOME: A free autologous mucosal graft (3.5 x 2.0 cm) was transplanted from the lower lip into the upper RE fornix. Six months after surgery, with therapeutic contact lenses, the need for tear supplementation was markedly reduced to 3 - 4 times/day in RE while it remained unchanged in LE. In RE, slit-lamp examination revealed decreases in the corneal stromal edema and in the diameter of neo-vessels associated with an improvement of visual acuity (counting fingers at 30 cm). Basal Schirmer test values were unchanged. It has to be mentioned that the improvement observed after surgery was markedly dependent on wearing a therapeutic contact lens. CONCLUSIONS: Free autologous buccal graft transplantation (with its presumably accessory salivary glands) in association with the use of a therapeutic contact lens can be an efficient approach to treat ocular complication following drug-induced TEN (Lyell's syndrome).

Reducing intraocular pressure: is surgery better than drugs?

Reducing IOP is presently the evidence based, most accepted and most practised therapeutical approach for glaucoma patients. Currently topical ocular hypotensive medications, with its different classes, as well as filtering surgery (trabeculectomy and non-penetrating glaucoma surgery) are in the forefront of therapeutic modalities for IOP reduction. This article looks at the potential advantages and disadvantages of topical medications versus filtering surgery. It does not directly address the question of initial treatment of glaucoma, or what is the better treatment of glaucoma, as other review articles had, but rather looks in a more specific on the pros and the cons of each in relation to IOP reduction. In other words this article deals with the situation once the decision has been made to reduce IOP.
