RESUMO

The primary objective of this study was to objectively compare the visual performance of patients following premium pseudophakic presbyopia corrections in different light combinations for near- and intermediate-vision activities of daily living (ADLs). This is a prospective, comparative study. A total of 75 patients populated three study groups: G1-patients with bilateral trifocal implantation, G2-patients with bilateral bifocal implantation, and G3-patients with bilateral monofocal implantation. All participants addressed 10 ADLs in nine combinations of light temperature (3000 K, 4000 K, and 6000 K) and light intensity (25 fc, 50 fc, and 75 fc) and declared their subjectively optimal light combination while reading. G2 and G3 had the best total ADL scores in 6000 K/75 fc, while G1 had the best total ADL score in 4000 K/75 fc. Total ADL, easy ADL, and moderate difficulty ADL scores were significantly better in G2, while difficult ADL score was significantly better in G1. The majority of all groups selected 6000 K/75 fc as the most comfortable light combination, and no group selected 3000 K and 25 fc. In conclusion, trifocal patients benefit from intense daylight, while bifocal and monofocal patients benefit from intense, cold lighting. Trifocal patients present superior near-vision capacity in difficult near-vision daily tasks, while bifocal patients present superiority in easy and moderate-difficulty ADLs.

RESUMO

OBJECTIVE: Dry eye disease (DED) is a multifactorial disease involving the tears and ocular surface. It impacts a patient's quality of life (QoL) and ability to perform daily activities. This study assessed the burden of self-reported DED among adults in eight European countries. DESIGN: Online cross-sectional survey. SETTING: General population in France, Italy, Germany, Greece, the Netherlands, Portugal, Spain and Sweden. PARTICIPANTS: Adults aged ≥18 years with (n=6084) and without (n=6161) self-reported DED were recruited via emails and screened. MAIN OUTCOME MEASURES: All participants completed National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) and EuroQol-5 Dimension-5 Level Questionnaire (EQ-5D-5L). All DED participants completed the Eye Dryness Score (EDS) Visual Analogue Scale, and Ocular Comfort Index and Work Productivity and Activity Impairment Questionnaire: Specific Health Problem questionnaires. In addition, half of the respondents with DED completed Survey A (Impact of Dry Eye on Everyday Life) and the other half completed Survey B (Standard Patient Evaluation of Eye Dryness Questionnaire) and Dry Eye Questionnaire-5. RESULTS: Participants with self-reported DED had lower functional vision and lower overall health status than participants without self-reported DED as measured by the NEI-VFQ and EQ-5D-5L, respectively.Increasing self-reported DED severity as measured by the EDS was shown to correspond with worse symptom severity/frequency, lower functional vision, higher impact on work productivity, daily activities and QoL. CONCLUSION: This study showed that patients' reported burden of self-reported DED was similar across the eight European countries. Those with self-reported DED reported lower health status and functional vision compared to those without self-reported DED and these parameters worsen with increasing disease severity.

RESUMO

PURPOSE: To validate the Democritus Digital Acuity and Reading Test (DDART) as a distance VA (dVA) test against a series of prevalent conventional distance vision charts. SETTING: Ophthalmology Department, University Hospital of Alexandroupolis, Alexandroupolis, Greece; Ophthalmology Department, AHEPA University Hospital, Thessaloniki, Greece; and Ophthalmica Institute of Ophthalmology & Microsurgery, Thessaloniki, Greece. DESIGN: Prospective multicenter validation study. METHODS: The distance best spectacle-corrected visual acuity (dBSCVA) was compared in normal (NVG) and low (LVG) vision participants against 4 prevalent conventional distance vision charts (ETDRS, Snellen, Landolt C, and Tumbling E) by a predefined 2.5-symbol noninferiority margin and intraclass correlation coefficients (ICCs). DDART's test-retest (TRT) reliability was assessed with ICCs. RESULTS: 534 participants (471 and 63 with normal and low vision, respectively) were included in the study. The mean difference between dBSCVA measured with DDART and conventional charts ranged between -0.84 and +0.85 symbols, without exceeding the 2.5-symbol noninferiority margin. ICCs indicated an excellent level of agreement for all patient groups (from 0.848 to 0.985). TRT reliability indicated differences below 1 symbol both for the NVG and LVG, with ICCs ranging between 0.912 and 0.964 for the 4 DDARTs. CONCLUSIONS: DDART was a valid web-based dVA test that provided reliable measurements in clinical and telemedical settings, both for normal and low vision patients.

RESUMO

Purpose. To report the acute development of hypopyon after primary cryopreserved amniotic membrane transplantation (AMT) for persistent corneal epithelial defect and sterile ulceration. Case Presentation. A selected case report of a 71-year-old male who underwent primary cryopreserved AMT for the management of long-standing corneal epithelial defects and stroma thinning. The patient developed 2 mm sterile hypopyon within 48 hours after AMT for corneal surface reconstruction. He responded well to the intensified routine postoperative topical treatment of steroid and antibiotic eye drops with the hypopyon resolving completely one week later. Five weeks after surgery, the corneal surface was smooth and epithelialized with no anterior chamber reaction or recurrence of hypopyon. Discussion. Hypopyon may develop as a rare complication of primary cryopreserved AMT for sterile corneal defects. It may be attributed to immunologic or hypersensitivity reaction and should be differentiated from active ocular infection as it resolves spontaneously with the routine postoperative topical treatment of steroid and antibiotic drops.

RESUMO

This interesting study raises a scientific issue for revisiting three important elements on diagnosis, use of preservatives and selection of the appropriate topical treatment. Itchy feeling can be encountered in other ophthalmic conditions misdiagnosed as allergy, benzalkonium chloride is responsible for surface toxicity resulting in reduced efficacy and tolerability of topical allergy medications and it should be avoided on the management of ocular allergy. Unpreserved ketotifen 0,025% has been shown to be the least toxic formulation being the optimum option for efficacy and tolerability on the management of ocular allergy.

RESUMO

Non-melanoma skin cancer (NMSC) is the commonest malignancy worldwide (>80% located in the head and neck area). The aim of this study was to assess risk factors predisposing to local recurrence of NMSC of the middle third of the face (MTF). This was a single-centre retrospective analysis of patients with NMSC of the MTF treated during 1995-2010. Data on epidemiological and tumour characteristics were collected. Survival analysis was performed and log-rank tests were used to compare differences in survival for each variable. A total of 531 patients with basal cell carcinoma (BCC) of the MTF were identified. Most tumours were nodular type (28.4%), located on the nose (34.3%), and confined to the dermis (75.5%). Negative margins were achieved in 91% of cases. Median follow-up time was 35 months and 15.2% of patients developed local recurrence. Incomplete excision was the only variable predisposing to local recurrence. The cohort also included 114 patients with squamous cell carcinoma (SCC). Most tumours were well differentiated (43.9%), located at the zygomatic area (49.1%), excised with negative margins (93%), and confined to the dermis (67.8%). At a median follow-up time of 42 months, local recurrence occurred in 15.7% of patients. Tumour size, depth of invasion, and prior history of head and neck SCC were risk factors for local recurrence. The variables predictive of recurrence of BCC were incomplete excision and for SCC tumour size, depth of invasion, and a prior history of head and neck SCC.

RESUMO

OBJECTIVE: To describe a clinical entity of upper eyelid margin and meibomian gland inversion (MGI) sequential to meibomian gland dysfunction (MGD), in the absence of eyelash ptosis, trichiasis or manifest marginal entropion. We highlight its clinical features, surgical management and outcomes. METHODS: We performed a retrospective analysis of symptomatic MGI cases refractory to conservative management who underwent surgery in our centre over a 4-year period. Anatomical correction, resolution of symptoms and possible complications are reported. RESULTS: A total of 21 eyelids of 13 patients (mean age: 68.5 ± 15.4, range: 32-88 years) were analysed. Symptomatic MGI patients were operated only if they have noted immediate comfort when we corrected the lid margin position with a cotton tip. Those with refractory superior punctate corneal staining (n = 14 eyes), blink-related discomfort (n = 8) and pseudo-blepharospasm (n = 3) reported complete postoperative resolution. Milder symptoms showed partial improvement: gritty feeling (79%), sore eye (80%) and watery eye (86%). However, symptoms of dry eye disease (DED) persisted in 88% of patients. One case recurred in 6 weeks and was offered revision surgery. Median follow-up was 5 (range: 3-12) months. CONCLUSION: Meibomian gland inversion (MGI) is a subtle clinical entity that can be easily overlooked. Symptoms are often attributed to DED or MGD alone. It is likely that MGI represents early upper lid margin anatomical changes secondary to MGD before cicatricial marginal entropion becomes clinically apparent. Recommended treatment is conservative with intensive lid hygiene and topical MGD management. However, refractory symptomatic cases who respond positively to a 'cotton-tip test' (reversal of lid margin malposition with a rolling cotton-tip) may benefit from surgical intervention with favourable anatomical and functional outcome.

RESUMO

PURPOSE: The pathogenesis of Graves' disease (GD) and orbitopathy (GO) is not completely elucidated. On the other hand, vitamin D receptor (VDR) gene polymorphisms have been associated with vulnerability to a plethora of chronic autoimmune diseases. The primary aim of this study was to synthesize evidence on the association between VDR gene polymorphisms and GD. Secondary aim was to investigate their association with GO. METHODS: A comprehensive search was conducted in PubMed, CENTRAL and Scopus, up to December 8, 2018. Data were expressed as odds ratio (OR) with 95% confidence intervals (CI). Heterogeneity was quantified with I2 index. RESULTS: Ten studies were included in the qualitative and quantitative analysis. TT subtype of TaqI polymorphism was associated with an increased risk of GD compared with Tt and tt polymorphisms (OR: 1.42; 95% CI, 1.05-1.94, p = 0.025), whereas tt was associated with a lower risk of GD, compared with TT and Tt polymorphisms (OR: 0.79; 95% CI, 0.62-0.99, p = 0.043). No association was found for ApaI, BsmI, and FokI polymorphisms. The bb subtype of BsmI polymorphism was associated with a lower risk in Asian, but with a higher GD risk in Caucasian populations, compared with BB/Bb subtypes. No eligible study was found regarding the association between VDR gene polymorphisms and the risk of GO. CONCLUSIONS: The TT subtype of the TaqI polymorphism was associated with a higher susceptibility for GD compared with Tt and tt. Regarding BsmI, the bb subtype was associated with increased GD risk in Caucasians, whereas it is protective in Asians.

RESUMO

Corneal nerves are key components of the physiological system that controls ocular surface homeostasis. The cornea is primarily innervated by the ophthalmic branch of the trigeminal nerves (cranial nerve V), which distend bilaterally from the pons. The nasociliary branch (afferent) of the ophthalmic nerve is sensory for cornea, eyelid and conjunctiva. These nerve fibres play a role in sensing temperature, chemical and mechanical stimuli, and pain, whereas, branches of the facial nerve (cranial nerve VII) contain motor nerves that control blinking and autonomic (sympathetic and a paucity of parasympathetic) fibres that stimulate tear production and secretion via feedback loops between the ocular surface, lacrimal glands and brain. Disruption of these nerves with interruption of neural feedback loops between the ocular surface and lacrimal glands can lead to corneal diseases such as dry eye disease (DED) and neurotrophic keratopathy (NK). Inversely, hypersensitivity of the nerve fibres and/or dysregulation of pain-controlling nervous centres may lead to neuropathic pain. Recently, medications that specifically target regeneration of corneal nerves have started to become available - and considering the high prevalence of diseases associated with corneal nerve dysfunction, these agents promise to fulfil a hitherto important unmet need. In this review, we explore the physiology of corneal nerves, the pathology of corneal nerve diseases and how these relate to neuropathic pain, NK and DED. We also discuss what novel treatments may be useful against diseases involving corneal nerves.

RESUMO

Intravenous (i.v.) glucocorticosteroids (GCs) constitute the first-line treatment for active and moderate-to-severe Graves' orbitopathy (GO). In cases of persistent disease, rituximab, a monoclonal anti-CD20 antibody, may be used, although studies have yielded conflicting results. In case 1, a 50-year-old female heavy smoker presented with severe bilateral disfiguring eyelid edema of four months, bilateral exophthalmos and a clinical activity score (CAS) of 5/7. Laboratory investigation showed thyrotoxicosis and high thyroid-stimulating immunoglobulin (TSI) levels [32 IU/L (normal <1.75]. After minor improvement by i.v. methylprednisolone and standard retrobulbar radiotherapy (20 Gy), her visual acuity progressively declined to "hand motion". Rituximab was administered (two pulses of 500 mg, two weeks apart), with significant response. At 3 1/2 years of follow-up, CAS is 0/7 and CD20+ lymphocytes remain at the lower normal range. In case 2, a 78-year-old non-smoker male was referred for management of severe active GO, one month after total thyroidectomy for Graves' thyrotoxicosis (TSI: 6.74 IU/L). Over the preceding two-three months, severe GO manifested with chemosis, constant diplopia, loss of color vision and acuity of 1/10 bilaterally (CAS: 7/7). Following partial response to i.v. methylprednisolone and concomitant radiotherapy, rituximab (two pulses of 500 mg each, two weeks apart), was administered. Vision partially recovered and GO remains in remission one year later, even after 131I (100 mCi) administration for papillary thyroid carcinoma (TSI: 0.9 IU/L and CD20+ count at the lower normal range). In conclusion, rituximab may be an effective second-line therapy in GO patients, providing long-lasting remission.

RESUMO

Dry eye disease (DED) is a common condition with signs and symptoms that vary depending on a wide range of environmental factors to which people are exposed in their daily lives. Factors such as variable temperature, airflow velocity, relative humidity, seasonality, and pollutants can alter the rate of tear film evaporation, improving or exacerbating symptoms of DED. Results from currently available clinical tests do not always correlate well with patient-reported symptoms, and the continually changing environment and variability in DED symptoms present challenges for the design and conduct of clinical trials. Controlled adverse environment chambers allow standardization of temperature, humidity, and airflow and may minimize potential confounding factors in clinical investigations. Their use can promote accurate study of the pathophysiology of DED, discovery of disease biomarkers, and assessment of the effect of various therapeutic approaches on patients' symptoms. Controlled adverse environment chambers have been used to simulate indoor surroundings such as airplane cabins and to test their effects on contact lens wearers. This review summarizes how these chambers may be useful for the development, approval, and differentiation of potential new treatments for DED.

RESUMO

Glaucoma therapy-related ocular surface disease (OSD) is a serious pathology with a broad spectrum of insidious clinical presentations and complex pathogenesis that undermines long-term glaucoma care. Preservatives, especially benzalkonium chloride (BAK), contained in topical intraocular pressure-lowering medications frequently cause or aggravate OSD in glaucoma. Management of these patients is challenging, and to date often empirical due to the scarcity of controlled long-term clinical trials. Most of the available data are extracted from case series and retrospective analysis. Preservative-free prostaglandins and prostaglandin/timolol fixed combinations are novel options developed to remove the harmful impact of preservatives, especially BAK, upon ocular tissues. Based on what is currently known on the value of preservative-free antiglaucoma therapies it is tempting to speculate how these new therapies may affect the future medical management of all glaucoma patients. This article provides a comprehensive and critical review of the current literature on preservative-free prostaglandins and preservative-free prostaglandin/timolol fixed combinations.

RESUMO

Meibomian gland dysfunction (MGD) is a common and chronic disorder that has a significant adverse impact on patients' quality of life. It is a leading cause of evaporative dry eye disease (DED), as meibomian glands play an important role in providing lipids to the tear film, which helps to retard the evaporation of tears from the ocular surface. MGD is also often present in conjunction with primary aqueous-deficient DED. Obstructive MGD, the most commonly observed type of MGD, is the main focus of this article. MGD is probably caused by a combination of separate conditions: primary obstructive hyperkeratinization of the meibomian gland, abnormal meibomian gland secretion, eyelid inflammation, corneal inflammation and damage, microbiological changes, and DED. Furthermore, skin diseases such as rosacea may play a part in its pathology. Accurate diagnosis is challenging, as it is difficult to differentiate between ocular surface diseases, but is crucial when choosing treatment options. Ocular imaging has advanced in recent years, providing ophthalmologists with a better understanding of ocular diseases. This review presents a literature update on the 2011 MGD workshop and an optimized approach to accurate diagnosis of MGD using currently available methods and tests. It also outlines the emerging technologies of interferometry, non-contact meibography, keratography and in vivo confocal laser microscopy, which offer exciting possibilities for the future. Selected treatment options for MGD are also discussed.

RESUMO

Dry eye disease (DED) results in tear film instability and hyperosmolarity, inflammation of the ocular surface and, ultimately, visual disturbance that can significantly impact a patient's quality of life. The effects on visual acuity result in difficulties with driving, reading and computer use and negatively impact psychological health. These effects also extend to the workplace, with a loss of productivity and quality of work causing substantial economic losses. The effects of DED and the impact on vision experienced by patients may not be given sufficient importance by ophthalmologists. Functional visual acuity (FVA) is a measure of visual acuity after sustained eye opening without blinking for at least 10 s and mimics the sustained visual acuity of daily life. Measuring dynamic FVA allows the detection of impaired visual function in patients with DED who may display normal conventional visual acuity. There are currently several tests and methods that can be used to measure dynamic visual function: the SSC-350 FVA measurement system, assessment of best-corrected visual acuity decay using the interblink visual acuity decay test, serial measurements of ocular and corneal higher order aberrations, and measurement of dynamic vision quality using the Optical Quality Analysis System. Although the equipment for these methods may be too large or unaffordable for use in clinical practice, FVA testing is an important assessment for DED.

RESUMO

Graves' orbitopathy (GO) is the main extrathyroidal manifestation of Graves' disease, though severe forms are rare. Management of GO is often suboptimal, largely because available treatments do not target pathogenic mechanisms of the disease. Treatment should rely on a thorough assessment of the activity and severity of GO and its impact on the patient's quality of life. Local measures (artificial tears, ointments and dark glasses) and control of risk factors for progression (smoking and thyroid dysfunction) are recommended for all patients. In mild GO, a watchful strategy is usually sufficient, but a 6-month course of selenium supplementation is effective in improving mild manifestations and preventing progression to more severe forms. High-dose glucocorticoids (GCs), preferably via the intravenous route, are the first line of treatment for moderate-to-severe and active GO. The optimal cumulative dose appears to be 4.5-5 g of methylprednisolone, but higher doses (up to 8 g) can be used for more severe forms. Shared decision-making is recommended for selecting second-line treatments, including a second course of intravenous GCs, oral GCs combined with orbital radiotherapy or cyclosporine, rituximab or watchful waiting. Rehabilitative treatment (orbital decompression surgery, squint surgery or eyelid surgery) is needed in the majority of patients when GO has been conservatively managed and inactivated by immunosuppressive treatment.

RESUMO

Meibomian gland dysfunction (MGD) is the most frequent cause of dry eye disease (DED). Eyelid inflammation, microbial growth, associated skin disorders as well as potentially severe corneal complications culminate to make MGD a complex multifactorial disorder. It is probable that MGD is a heterogeneous condition arising from any combination of the following five separate pathophysiological mechanisms: eyelid inflammation, conjunctival inflammation, corneal damage, microbiological changes and DED resulting from tear film instability. The pathogenesis of both MGD and DED can be described in terms of a 'vicious circle': the underlying pathophysiological mechanisms of DED and MGD interact, resulting in a double vicious circle. The MGD vicious circle is self-stimulated by microbiological changes, which results in increased melting temperature of meibum and subsequent meibomian gland blockage, reinforcing the vicious circle of MGD. Meibomian gland blockage, dropout and inflammation directly link the two vicious circles. MGD-associated tear film instability provides an entry point into the vicious circle of DED and leads to hyperosmolarity and inflammation, which are both a cause and consequence of DED. Here we propose a new pathophysiological scheme for MGD in order to better identify the pathological mechanisms involved and to allow more efficient targeting of therapeutics. Through better understanding of this scheme, MGD may gain true disease status rather than being viewed as a mere dysfunction.

RESUMO

Dry eye disease (DED), a multifactorial disease of the tears and ocular surface, is common and has a significant impact on quality of life. Reduced aqueous tear flow and/or increased evaporation of the aqueous tear phase leads to tear hyperosmolarity, a key step in the vicious circle of DED pathology. Tear hyperosmolarity gives rise to morphological changes such as apoptosis of cells of the conjunctiva and cornea, and triggers inflammatory cascades that contribute to further cell death, including loss of mucin-producing goblet cells. This exacerbates tear film instability and drives the cycle of events that perpetuate the condition. Traditional approaches to counteracting tear hyperosmolarity in DED include use of hypotonic tear substitutes, which have relatively short persistence in the eye. More recent attempts to counteract tear hyperosmolarity in DED have included osmoprotectants, small organic molecules that are used in many cell types throughout the natural world to restore cell volume and stabilize protein function, allowing adaptation to hyperosmolarity. There is now an expanding pool of clinical data on the efficacy of DED therapies that include osmoprotectants such as erythritol, taurine, trehalose and L-carnitine. Osmoprotectants in DED may directly protect cells against hyperosmolarity and thereby promote exit from the vicious circle of DED physiopathology.

RESUMO

Purpose. To report a case of Alternaria alternata keratitis in a patient with a corneal transplant in her right eye due to bullous pseudophakic keratopathy. Methods. A 66-year-old female underwent a full-thickness keratoplasty in her right eye due to bullous pseudophakic keratopathy. Three weeks after keratoplasty, epithelial edema and a stromal opacity with an infiltrate and development of peripheral corneal opacities appeared. The diagnosis of Alternaria alternata keratitis was made. Results. The patient underwent a second keratoplasty, due to the corneal melting as a result of the fungal infection. She was also given combined antifungal treatment locally and systematically. Conclusion. Corneal transplantation alone would not have been sufficient to keep the fungus in the anterior portion of the eye. Combined antifungal treatment, locally and systematically, was important in attempting to prevent the further spread of the fungus to the interior of the eye. To our knowledge, the case presented here is only the second one in the literature concerning a keratomycosis due to Alternaria alternata corneal transplant infection.

RESUMO

The management of thyroid eye disease (TED) remains a therapeutic challenge. The current established therapies are unsatisfactory in one-third of the patients and have many limitations. Rituximab (RTX) is a CD20+ B-cell-depleting monoclonal antibody approved for the treatment of non-Hodgkin lymphomas, chronic lymphocytic leukemia, and rheumatoid arthritis. The early experience with RTX suggests that it is a promising alternative therapy for TED. Rituximab may compare favorably to the conventional glucocorticoid therapy and causes less collateral damage than retrobulbar orbital radiation and decompression surgery. In addition, the preliminary studies on RTX's proposed mechanism of action have revealed new insights into the pathogenic role of B-cells in TED. We summarize the current literature on the clinical application of RTX in TED and discuss its putative mechanisms of action.

RESUMO

BACKGROUND: Entropion is a condition in which the eyelid margin turns in against the eyeball. Involutional or senile entropion is one of the most common lower lid malpositions in the elderly. The interventions described and currently used for the treatment of this condition are surgical in nature, although non-surgical temporary medical treatment for the early stages of entropion has also been reported. The relative effectiveness of these interventions has not yet been resolved. OBJECTIVES: To examine the effect of interventions for involutional entropion and to assess whether any method is superior to any other. SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2011, Issue 10), MEDLINE (January 1950 to November 2011), EMBASE (January 1980 to November 2011), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com),ClinicalTrials.gov (http://clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 2 November 2011. We also searched oculoplastic textbooks, conference proceedings from the European and American Society of Ophthalmic Plastic and Reconstructive Surgery (ESOPRS, ASOPRS), European Ophthalmological Society (SOE), the Association for Recearch in Vision and Ophthalmology (ARVO) and American Academy of Ophthalmology (AAO) for the years 2000 to 2009 to identify relevant data. We attempted to contact researchers who are active in this field for information about further published or unpublished studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) with no restriction on date or language comparing two or more surgical methods for correction of involutional lower eyelid entropion in people older than 60 years of age with involutional lower lid entropion. DATA COLLECTION AND ANALYSIS: Each review author independently assessed study abstracts identified from the electronic and manual searches. Author analysis was then compared and full papers for appropriate studies were obtained according to the inclusion criteria. Disagreements between the authors were resolved by discussion. MAIN RESULTS: We identified one RCT which met our inclusion criteria and was included in this review. Sixty-three participants with primary involutional lower eyelid entropion were randomised to everting sutures alone or everting sutures with a lateral tarsal strip. Eight participants were lost to follow-up. The trial indicates that the combined procedure for horizontal and vertical eyelid tightening in the form of everting sutures and lateral tarsal strip is highly curative for involutional entropion compared to vertical tightening in the form of everting sutures alone. The superiority of the combined approach is also supported by many good quality uncontrolled studies on specific surgical procedures but these were not included in the analysis as they were not part of the inclusion criteria. AUTHORS' CONCLUSIONS: A single RCT showed that the combination of horizontal and vertical eyelid tightening with everting sutures and lateral tarsal strip is highly efficient for entropion compared to vertical tightening with everting sutures alone. Retrospective case series studies also support the combined surgical repair but details from these studies on specific surgical techniques cannot be included in the analysis.Evidence from a single RCT is unlikely to change clinical practice and thus it is still our view that there is a clear need for more randomised studies comparing two or more surgical techniques for entropion surgery addressing the recurrence and complications rate.
