Bulbar Redness and Dry Eye Disease: Comparison of a Validated Subjective Grading Scale and an Objective Automated Method.

SIGNIFICANCE: In this study, assessments of conjunctival redness were performed to evaluate whether patients with or without dry eye disease (DED) could be discriminated based on this measure. Our findings suggest that subjectively grading redness by quadrant, as opposed to automated en face measurements, may be more suitable for this purpose. PURPOSE: This study aimed to quantify bulbar redness using the validated bulbar redness (VBR) grading scale and an automated objective method (Oculus Keratograph 5M; K5M) in participants with DED and non-DED controls. METHODS: Participants with DED (Ocular Surface Disease Index score ≥20 and Oxford scale corneal staining ≥2) and controls (Ocular Surface Disease Index score ≤10 and corneal staining ≤1) attended two study visits. In part 1A of visit 1, baseline bulbar redness was graded with the VBR scale in each conjunctival quadrant of both eyes, followed by automated measurements of temporal and nasal redness with the K5M. This was immediately followed by part 1B, during which a topical vasoconstrictor was instilled into both eyes. Redness assessments were repeated 5 and 30 minutes after instillation with both instruments. Participants returned 14 days later for visit 2, where the same assessments as for visit 1A were repeated. RESULTS: Seventy-four participants (50 DED and 24 controls) completed the study. There were statistically significant differences in redness between the DED and control groups when assessed with the VBR scale (14/16 comparisons; all, P < .05), whereas no significant differences in K5M-derived redness between the DED and non-DED groups were found at any location or time point. Both subjective and objective instruments detected statistically significant reductions in redness 5 and 30 minutes after instillation of the vasoconstrictor (all, P < .01). CONCLUSIONS: Although both subjective and objective instruments were sensitive to detecting changes in redness induced by vasoconstriction, statistically significant differences in redness between DED and control groups were only found using the VBR scale.

Lid-parallel conjunctival fold (LIPCOF) morphology imaged by optical coherence tomography and its relationship to LIPCOF grade.

PURPOSE: Lid-parallel conjunctival folds (LIPCOF) are a well-accepted clinical sign in dry eye diagnosis. Commonly, LIPCOF is classified by grading the number of folds observed by slit-lamp microscope. This study investigated the relationship between subjective grading scale and LIPCOF morphology imaged by optical coherence tomography (OCT). METHODS: Temporal and nasal LIPCOF of 42 subjects (mean age 27.3 ± 8.4 (SD) years; 13 M, 29 F) were observed and classified by an experienced optometrist using the Pult LIPCOF grading scale (0: no permanent, lid-parallel conjunctival fold; 1: one fold; 2: two folds, 3: three or more folds). Additionally, LIPCOF cross-sectional area (LIPCOF-A) and fold count (LIPCOF-C), as imaged by OCT (Cirrus HD; Carl Zeiss Meditec, Jena, Germany), were analysed with ImageJ 1.50 (http://rsbweb.nih.gov/ij). Correlations between subjective grading and LIPCOF-A and LIPCOF-C were analysed by Spearman correlation, differences between subjective grading and LIPCOF-C were analysed by Wilcoxon test. RESULTS: For temporal and nasal sectors, mean subjective LIPCOF grade was 1.43 ± 0.86 grade units and 0.57 ± 0.80 grade units, mean LIPCOF-C was 1.67 ± 0.82 folds and 0.69 ± 0.78 folds, and mean LIPCOF-A was 0.0676 ± 0.0236mm2 and 0.0389 ± 0.0352 mm2, respectively. Subjective temporal and nasal LIPCOF grade was significantly correlated to LIPCOF-C (r = 0.610, p < 0.001 and r = 0.645, p < 0.001, respectively), and to LIPCOF-A (r = 0.612, p < 0.001 and r = 0.583, p < 0.001, respectively). LIPCOF-C was not statistical different to subjective LIPCOF grade (p = 0.07 and p = 0.239; temporal and nasal sectors, respectively). CONCLUSIONS: OCT allows for better imaging of finer details of LIPCOF morphology, and especially of LIPCOF area. OCT evaluation of LIPCOF area correlated well with subjective grading and appears to be a promising objective method for LIPCOF classification.

Hyperemia Analysis Software for Assessment of Conjunctival Hyperemia Severity.

PURPOSE: We developed a hyperemia analysis software, which can quantitatively assess the degree of conjunctival hyperemia, and evaluated the reproducibility and reliability of its percent coverage. In addition, we compared the clinical grading and the percent coverage to examine the applicability of the software analysis. METHODS: We took images of the temporal conjunctiva with slit lamp microscopes. We used our hyperemia analysis software to detect blood vessels in the region of interest using its image processing capabilities and obtained a ratio of the area occupied by blood vessels to the rest of the area. In addition, we used the clinical evaluation criteria of the Japanese guidelines for allergic conjunctival diseases 2017 to clinically grade the hyperemia in each eye. Nine evaluators examined the images and graded the severity of hyperemia into four stages. We looked for a statistical correlation between the results of the hyperemia analysis software and the clinical grading. RESULTS: The percent coverage of the blood vessels in the region of interest calculated by the hyperemia analysis software correlated with the arithmetic average of our clinical grading (r = 0.953; 95% CI, 0.8470340-0.9862136). CONCLUSION: The percent coverage from our hyperemia analysis software reflects the clinical grading score, suggesting that our software can be used to obtain a detailed analysis of conjunctival hyperemia.

Validation of International Chronic Ocular Graft-Versus-Host Disease (GVHD) Group Diagnostic Criteria as a Chronic Ocular GVHD-Specific Metric.

PURPOSE: To validate the International Chronic Ocular GVHD Consensus Group (ICCGVHD) diagnostic criteria for chronic ocular chronic graft-versus-host disease (GVHD), by comparing results with comprehensive ophthalmic evaluation after allogeneic hematopoietic stem cell transplantation. METHODS: A single-institution retrospective chart review was conducted on patients who underwent hematopoietic stem cell transplantation at Vanderbilt University Medical Center in Nashville, TN, from January 1, 2002, through April 17, 2014. A total of 344 patients were eligible for the study. Data collected include the Schirmer test score, corneal fluorescein staining, Ocular Surface Disease Index, conjunctival injection, and presence or absence of systemic GVHD. The diagnosis of chronic ocular GVHD in each participant and determination of the overall severity score were determined based on the newly proposed ICCGVHD diagnostic criteria and compared with the best clinical practice (BCP) score. RESULTS: Chronic ocular GVHD was diagnosed in 141/344 (41%) participants, of these, 86 (61%) had complete charts. Based on the BCP score, 1.2% had none, 38.4% mild, 47.7% moderate, and 12.8% had severe chronic ocular GVHD. Based on the ICCGVHD, 34.8% had none, 59.3% mild/moderate, and 5.8% had severe chronic ocular GVHD. The clinical diagnostic stages of chronic ocular GVHD by BCP and ICCGVHD criteria had slight agreement (kappa statistic 0.187, with 95% confidence interval 0.049-0.321), with a higher correlation seen in those with severe chronic ocular GVHD. CONCLUSIONS: The newly proposed ICCGVHD diagnostic criteria can be used reproducibly for the diagnosis and determination of severity of chronic ocular GVHD. However, larger prospective studies are needed to further validate it.

Conjunctival Primary Acquired Melanosis: Is It Time for a New Terminology?

PURPOSE: To review the diagnostic categories of a group of conditions referred to as "primary acquired melanosis." DESIGN: Literature review on the subject and proposal of an alternative diagnostic schema with histopathologic and immunohistochemical illustrations. METHODS: Standard hematoxylin-eosin-stained sections and immunohistochemical stains for MART-1, HMB-45, microphthalmia-associated transcription factor (MiTF), and Ki-67 for calculating the proliferation index are illustrated. RESULTS: "Melanosis" is an inadequate and misleading term because it does not distinguish between conjunctival intraepithelial melanin overproduction ("hyperpigmentation") and intraepithelial melanocytic proliferation. It is recommended that "intraepithelial melanocytic proliferation" be adopted for histopathologic diagnosis. Atypical proliferations are characterized either by bloated dendritic melanocytes with enlarged cell components (dendrites, cell bodies, and nuclei) or by epithelioid melanocytes without dendrites. Atypical polygonal or epithelioid pagetoid cells may reach higher levels of the epithelium beyond the basal layer. Immunohistochemistry defines the degree of melanocytic proliferation or the cellular shape (dendritic or nondendritic) (MART-1, HMB-45) or identifies the melanocytic nuclei (MiTF). Intraepithelial melanocytic proliferation without atypia represents increased numbers of normal-appearing dendritic melanocytes (hyperplasia or early neoplasia) that generally remain confined to the basal/basement membrane region. Intraepithelial nonproliferative melanocytic pigmentation signifies the usually small number of conjunctival basal dendritic melanocytes that synthesize increased amounts of melanin that is transferred to surrounding keratinocytes. CONCLUSION: All pre- and postoperative biopsies of flat conjunctival melanocytic disorders should be evaluated immunohistochemically if there is any question regarding atypicality. This should lead to a clearer microscopic descriptive diagnosis that is predicated on an analysis of the participating cell types and their architectural patterns. This approach is conducive to a better appreciation of features indicating when to intervene therapeutically. An accurate early diagnosis should forestall unnecessary later surgery.

The measurement of bulbar hyperemia: challenges and pitfalls.

PURPOSE: To review methods of assessing bulbar redness, particularly with respect to the practicality of comparing different rating systems. METHODS: The published literature was reviewed and discussed by a panel of experts and a narrative review prepared. RESULTS: Bulbar hyperemia is a common clinical sign and an important indicator of ocular disease. As bulbar hyperemia is a frequent side effect of topical glaucoma medications, accurate objective measurement is important to allow comparison of clinical studies. A number of different measurement systems have evolved to allow quantification of subjectively assessed redness to be rendered into a form that allows between-treatment comparisons and longitudinal changes in both clinical research and practice. Whereas widespread use of image-based rating scales has improved the assessment of bulbar redness in clinical practice and clinical research, these techniques are less than ideal. The scales are subject to an intrinsic subjectivity and are suboptimal in differentiating the physiologic phenomenon of bulbar hyperemia. There is also a degree of interobserver and intraobserver variation; in some studies, average variation in scores exceed half the extent of the whole scale. Moreover, a lack of interscale validation has led to confusion in comparing the results from clinical studies that use different scales. In a recent series of studies, cross-calibration between the various scales in use has been attempted. CONCLUSIONS: Whereas naive comparisons between the results obtained in studies using different bulbar redness scales can lead to erroneous conclusions, the tools exist to permit meaningful comparisons between rating systems and scales.

Severity of acute ocular involvement is independently associated with time to resolution of ocular disease in toxic epidermal necrolysis patients.

PURPOSE: Toxic epidermal necrolysis (TEN) is a severe, life-threatening mucocutaneous disorder that frequently involves the ocular surface. This study aims to investigate the natural history and resolution of acute ocular involvement in patients with TEN admitted to the intensive care unit (ICU). METHODS: Case notes of patients admitted to ICU with TEN at a tertiary referral centre in a 9-year period were retrospectively reviewed. Patients' characteristics, severity of ocular involvement, SCORTEN systemic severity score and treatment were correlated with resolution of ocular involvement and time to resolution. RESULTS: Nine out of 10 (90%) patients had ocular involvement with 4 graded as mild, 2 as moderate and 3 as severe. All had bilateral ocular disease. The median length of hospital stay was 28 days and the median time to resolution of ocular involvement was 19 days. Four out of 9 (44%) patients still had active ocular disease at the time of discharge. Only older age (p=0.032) and a milder grade of ocular disease (p=0.001) were significantly associated with resolution of ocular disease. In a multivariable Cox-regression model, only a milder grade of ocular disease remained independently associated with time to resolution of ocular disease (p=0.006). CONCLUSIONS: Grading of acute ocular disease severity does not reflect systemic disease severity and is significantly associated with resolution and time to resolution of ocular involvement in TEN. The high rate of ocular involvement in patients with TEN and relatively large proportion of patients with active disease on discharge reiterates the need for constant ophthalmological monitoring of these patients.

Short-term influence of aspirating speculum use on dry eye after cataract surgery: a prospective study.

PURPOSE: The aim of this study was to investigate the short-term influence of the use of an aspirating speculum on dry eye after performing cataract surgery. METHODS: This study was conducted using a prospective, consecutive, comparative, interventional case series of 58 eyes of 58 patients who underwent clear corneal cataract surgery; 29 eyes were treated using an aspirating speculum, and 29 eyes were treated without using a nonaspirating speculum. The main outcome measures were sequential changes of dry eye parameters including conjunctival staining, tear film break-up time (tBUT), conjunctivochalasis grades, and ocular surface disease index (OSDI). RESULTS: In the nonaspirating speculum group, tBUT and conjunctivochalasis grades were aggravated on day 1 postoperatively (P < 0.001), but conjunctival staining and OSDI did not show any significant change during the follow-up. In the aspirating speculum group, significant aggravation was observed by conjunctival staining on day 1 postoperatively (P = 0.001), tBUT and conjunctivochalasis grades were evaluated on day 1 and day 7 postoperatively (P < 0.001), and the OSDI was evaluated on day 7 postoperatively (P = 0.011). CONCLUSIONS: The use of an aspirating speculum aggravated dry eye parameters during the early postoperative period. Although these parameters returned to their preoperative values at 1 month postoperatively, the use of an aspirating speculum has the potential to aggravate dry eyes after cataract surgery is performed.

Conjunctivochalasis as a contributing factor for the development of ocular surface disease in medically treated glaucoma patients.

PURPOSE: To evaluate the impact of conjunctivochalasis (CCh) and its severity on the ocular surface parameters of glaucoma subjects treated with topical antiglaucomatous medication. MATERIALS AND METHODS: One hundred patients with the clinical diagnosis of glaucoma were recruited for this study. CCh was graded based on the extent of inferior lid margin involvement as follows: 1=single (temporal) location, 2=two locations (nasal and temporal), and 3=whole lid. For all the subjects, the break-up time (BUT), lissamine green (LG) staining, and Schirmer test (under topical anesthesia) was performed for both eyes. Ocular Surface Disease Index (OSDI) questionnaire scores were also noted for each subject. Student t test, Mann-Whitney U test, and Kruskal-Wallis test was used for statistical evaluations. RESULTS: Sixty-three subjects had evidence of CCh; 32 had grade 1, 24 had grade 2, 7 had grade 3 CCh, and 37 glaucoma patients had no evidence of CCh. There were significant differences in the BUT scores (7.2±2.7 vs. 10.1±2.4 s, P<0.001), Schirmer values (7.7±3.9 vs. 13.3.±4.0 mm, P<0.001), LG staining score (1.6±1.0 vs. 0.3±0.5, P<0.001), and the OSDI scores (19.4±17.2 vs. 6.7±5.2, P<0.001) between patients who had CCh and those without CCh. The BUT scores and Schirmer test values of patients with grades 2 and 3 CCh were significantly lower than those of grade 1 CCh and those without CCh (P<0.001). The LG grading and OSDI scores were significantly higher in grade 2 and 3 patients as compared with those with grade 1 CCh and those without CCh (P<0.001). CONCLUSIONS: The functional characteristics of the ocular surface appear to be adversely influenced by the presence and the extent of CCh in glaucoma patients.

New approach for conjunctivochalasis using an argon green laser.

PURPOSE: To evaluate the effectiveness of conjunctivoplasty using an argon green laser in symptomatic patients with conjunctivochalasis (CCh). METHODS: Twenty-nine eyes of 18 patients with various grades of CCh were included in this study. All the patients, who were refractory to the conventional therapy, were treated using an argon green laser. The ocular symptoms and signs, including the CCh grade, the tear Ocular Surface Disease Index, the breakup time, the Schirmer test, and the abnormal ocular surface findings, were evaluated preoperatively and postoperatively. RESULTS: The mean age of the patients was 69.1 ± 8.4 years. The grade of CCh in 25 eyes (86%) decreased at 6 months after the laser conjunctivoplasty. When the grade reduction rates were calculated, the reduction rates of grades 1, 2, and 3 were 100%, 69%, and 48%, respectively. Most of the patients showed a significant symptomatic improvement, and the Ocular Surface Disease Index scores decreased from 0.41 to 0.22 (P < 0.001). The breakup time increased from 9.1 to 10.2 (P = 0.007), but the Schirmer test results did not show any differences after the surgery (P = 0.257). CONCLUSIONS: Conjunctivoplasty using an argon green laser is a simple and effective choice to treat symptomatic patients with CCh, especially in cases of mild-to-moderate grade CCh.

Pattern of conjunctival masses seen at Guinness Eye Centre Luth Idi-Araba.

BACKGROUND: Conjunctival masses are growth on the surface of the outer eye; which may represent benign or malignant transformations. OBJECTIVE: To determine the pattern of presentation of conjunctival masses at the Guinness Eye Centre (GEC), Lagos University Teaching Hospital (LUTH) Idi-Araba over a 13 year period (Jan 1995-Dec 2007). METHOD: A retrospective review of the clinical notes of all patients that presented to GEC with conjunctival masses during the study period was carried out. The bio-data, clinical features, stage, laterality and associated features of the masses were noted. The diagnosis, treatment and complications of treatment were also recorded. RESULTS: Case notes of 612 eyes of 393 patients were included in the study. There were 219 (55.7%) males, 174 (44.3%) females with ages ranging from 4-85 years with a male to female ratio of 1.26: 1. Three hundred and eighty-eight patients (98.7%) presented as elective cases to the outpatient department while 5 (1.3%) presented as emergencies on account of associated ocular inflammation. There were 220 (56%) bilateral masses while 44% were uniocular. Pterygium was the leading conjunctival mass affecting 548 eyes (89.5%) of 329 patients. Pingueculae occurred in 53 eyes (8.7%), conjunctival cysts in 5 (0.8%) eyes, neoplastic growths in 3 (0.5%) eyes, conjunctival granulomas in 2 (0.3%) eyes and limbal teratoma in 1 (0.2%) eye. Most of these patients defaulted from surgery as only 141 eyes (23%) of 121 patients had surgery. Post-operative complications occurred in 33 eyes (5.4%) of 30 patients. The commonest postoperative complication was pterygium recurrence which occurred in 18 eyes of 15 patients. CONCLUSION: Pterygium was the commonest conjunctival mass and preventive strategies need to be advocated. Prevention of recurrence remains a challenge in the management of pterygium as recurrence after surgical excision occurred in 13.2% of eyes. Our study however did not confirm outdoor occupations as a risk factor for pterygium.

Conjunctivochalasis: associations with pinguecula in a hospital-based study.

PURPOSE: To assess the relationship between the prevalence and severity of conjunctivochalasis and pinguecula. METHODS: Cross-sectional, consecutive case study conducted at the university hospital of University of Tokyo Graduate School of Medicine. A total of 1061 patients aged from 1 to 94 years were enrolled. The grade and other parameters of conjunctivochalasis (classified into three locations: nasal, middle and temporal) and the grade of pinguecula located on the nasal or temporal conjunctiva were determined in all subjects. Patients were also divided into 5 or 10 age groups. RESULTS: The severity of conjunctivochalasis affecting the nasal and temporal bulbar conjunctiva was significantly correlated with the grade of pinguecula located on the nasal and temporal conjunctiva in each age group (p < 0.05). Pinguecula was independently associated with conjunctivochalasis (nasal: odds ratio [OR] = 1.44; temporal: OR = 1.43) after adjustment for age. CONCLUSION: This was the first assessment of the relation between the grade of conjunctivochalasis and pinguecula in a large consecutive series of patients. Our results suggest that the prevalence and severity of conjunctivochalasis are related to the presence of pinguecula.

Ocular and oral grading of mucous membrane pemphigoid.

BACKGROUND: A variety of methods have been described for grading ocular mucous membrane pemphigoid (MMP), each with their own limitations. In contrast, there are no reported grading systems for involvement of the oral mucosa. We wished to evaluate two ocular (one established and one proposed) and an oral mucosal grading system for MMP. METHODS: Patients with MMP were assessed by three ophthalmologists and two oral medicine physicians. Ocular disease was graded using the system described by Rowsey and a proposed system based on measurement of vertical depth and horizontal width measured from the bulbar conjunctival aspect. Oral assessment used a 'mucosal disease severity score' originally described for lichen planus, in which 17 areas of the mouth are scored for involvement, together with a pain score. Levels of agreement were evaluated using Fleiss' Kappa Statistic (k). RESULTS: Forty-four patients with MMP encompassing mild to severe disease were included. Good levels of agreement were observed between observers for both vertical (k:0.86) (upper 95% CI: 1.03 mm) and horizontal (k:0.80) (upper 95% CI: 3.01 mm) involvement for the proposed ocular system and the Rowsey system (k: 0.83) (upper 95% confidence interval: 3.19 mm). There was a high coefficient of determination (R(2)) between the ocular grading systems (0.81, p < 0.01). Oral grading showed excellent levels of agreement (k: 0.71) between observers. There was no significant association between the severity of oral and ocular disease using described grading systems. CONCLUSIONS: The proposed grading systems for both oral and ocular involvement in MMP are easy to use, and show good agreement between observers. The proposed ocular system correlates well with a currently used system, and overcomes some of the difficulties encountered with existing systems. For the individual patient, changes greater than 1.5 mm (vertical) and 3 mm (horizontal) are significant. This may increase our ability to detect change or disease progression. Although the risk of ocular involvement in patients with only oral involvement has been demonstrated, the severity of oral and ocular disease are not well-correlated, due in part to an absence of an ocular disease activity score.

Assessing the severity of conjunctivochalasis in a senile population: a community-based epidemiology study in Shanghai, China.

BACKGROUND: In a previous hospital-based study, conjunctivochalasis was diagnosed in 85.24% of 1416 patients aged 1 to 94 years and in 98.5% of patients aged 60 or older. This report is the first to present data from a large scale epidemiologic study on conjunctivochalasis in a community-based population, thereby helping to better identify the severity of conjunctivochalasis in the general population. METHODS: This community-based epidemiologic study was conducted to evaluate prevalence rates and related factors of conjunctivochalasis among people over 60 years old in the CaoYangXinCun community, Shanghai, China. Cluster sampling was used in randomly selected local residents aged no less than 60 years. A cross-sectional study using a slit-lamp ophthalmoscope for examination was carried out from September 2008 to October 2008. A modified grading system based on the well-accepted Meller and Tseng's system was used. SPSS10.0 software was used for data and statistical analysis. RESULTS: A total of 2110 residents took part in this study, with a response rate of 94.85%. Among these, 930 cases were confirmed as conjunctivochalasis, with a prevalence rate of 44.08%. The prevalence rate increased with age (X2 = 10.44, P < 0.01). A total of 1762 eyes were confirmed as conjunctivochalasis eyes. Of these eyes, 943 were classified as Grade I (53.52%), 647 as Grade II (36.72%), 162 as Grade III (9.19%), and the remaining 10 eyes as Grade IV (0.57%). The conjunctiva usually accumulated on the nasal and temporal areas of the conjunctival sac (944 eyes, 53.58%). CONCLUSIONS: Although the rate estimated in the present study is not as high as reported in the former hospital-based study, conjunctivochalasis is considered a common age-related eye disease, deserving more attention to its early diagnosis.

Imaging lid-parallel conjunctival folds with OCT and comparing its grading with the slit lamp classification in dry eye patients and normal subjects.

PURPOSE: To visualize and describe the morphologic appearance of lid-parallel conjunctival folds (LIPCOFs) by using optical coherence tomography (OCT) and to relate it to dry eye signs and symptoms. METHODS: The LIPCOF grade, noninvasive tear film breakup time (NIBUT), lipid layer interference pattern, and dry eye symptoms were recorded in 17 normal subjects and 33 patients with dry eye. LIPCOFs were evaluated with a slit lamp and visualized by OCT. Three different algorithms for OCT were developed to grade LIPCOFs according to tear meniscus height or the covering tear film on the folds. RESULTS: The three OCT methods showed significant correlation with the slit lamp method (r = 0.470-0.473, P < 0.01). The OCT LIPCOF imaging methods were independent of NIBUT. The Dry Eye Questionnaire (DEQ) scores correlated with the height of the folds and the absence of tear film coverage of the folds (r = 0.574, P < 0.001 and r = -0.527, P < 0.001, respectively). The OCT LIPCOF grades correlated with the DEQ scores (r = 0.494, P < 0.001 and r = 0.310, P = 0.029, respectively). The slit lamp grade did not correlate with the DEQ scores in the whole population, but did in the normal group (r = 0.458, P = 0.024). The OCT LIPCOF grades showed inverse correlation with lipid pattern in the normal group (r = -0.422-0.481, P = 0.05); however, this association disappeared in the dry eye group. CONCLUSIONS: OCT enabled a noninvasive, high-resolution method of imaging, evaluating, and classifying LIPCOFs. These new classifications correlated well with the slit lamp grade and the DEQ scores, promising a new, more objective evaluation of dry eye.

Quantitative evaluation of ocular surface inflammation in patients with different grade of conjunctivochalasis.

PURPOSE: To evaluate and compare HLA-DR expression of conjunctival epithelial cells in different grade of conjunctivochalasis (CCh). PATIENTS AND METHODS: Thirty patients and seven healthy subjects underwent clinical examination, grading of CCh by lid-parallel conjunctival fold (LIPCOF) test, and impression cytology of the bulbar conjunctiva. HLA-DR expression was analyzed by flow cytometry. Schirmer test, tear break-up time, and vital staining were also performed. RESULTS: Patients who presented with mild and moderate CCh showed a similar expression of HLA-DR to normal subjects. A significant increase (p < 0.005) of HLA-DR was found in patients with severe CCh. Positive correlation was found between fluorescein staining and HLA-DR expression (r = 0.36, p = 0.009) and between lissamine-green staining and HLA-DR expression (r = 0.30, p = 0.027). Neither correlation was found between Schirmer test nor break up time and HLA-DR expression. CONCLUSION: Inflammation plays a pivotal role on the ocular surface of patients with severe CCh. Since mild and moderate CCh HLA-DR expression was similar to normal controls, we can speculate that the source of inflammation could be the presence of conjunctival folds.

Simple surgical approach with high-frequency radio-wave electrosurgery for conjunctivochalasis.

OBJECTIVE: To introduce a new simple surgical approach with high-frequency radio-wave electrosurgery to reduce conjunctivochalasis (CCh). DESIGN: Prospective, noncomparative, interventional case series analysis. PARTICIPANTS: Twelve patients (20 eyes) with CCh were recruited from the outpatient service of the Department of Ophthalmology, Kangbuk Samsung Hospital, Seoul, Korea. METHODS: On the inferior bulbar conjunctiva, subconjunctival coagulation was performed with a fine-needle electrode using a high-frequency radio-wave electrosurgical unit (Ellman Surgitron; Ellman International, Inc., Hewlett, NY) in coagulation mode. MAIN OUTCOME MEASURES: Conjunctivochalasis grade; epiphora and dry eye symptoms (the Ocular Surface Disease Index [OSDI]; Allergan Inc., Irvine, CA, holds the copyright); and intraoperative and postoperative complications. RESULTS: Eighteen eyes (90%) recovered a smooth, wet, and noninflamed conjunctival surface within 1 month and remained stable for a follow-up period of 3 months. At 3 months postoperatively, 18 eyes (90%) had grade 0 CCh. There was a statistically significant decrease of the OSDI score at 3 months postoperatively (P < 0.001). CONCLUSIONS: A surgical approach with high-frequency radio-wave electrosurgery produced a significant reduction in CCh and an improvement in symptoms. Radio-wave surgical techniques represent a favorable alternative to surgical treatment of CCh.

Combination of rituximab and intravenous immunoglobulin for recalcitrant ocular cicatricial pemphigoid: a preliminary report.

PURPOSE: To compare the effectiveness and safety of the combination therapy of rituximab (RTX) and intravenous immunoglobulin (IVIg) to other immunosuppressive regimens in the treatment of ocular cicatricial pemphigoid (OCP). DESIGN: Retrospective, comparative, interventional case series. PARTICIPANTS: Twelve patients with OCP. METHODS: We reviewed medical records of 12 patients with OCP. Ten of the 12 patients were blind in 1 eye after initial systemic immunosuppressive therapies (phase 1 treatment). The patients were then divided into 2 groups based on treatments received during phase 2. The study group consisted of 6 patients who received the combination of RTX and IVIg during phase 2 of their treatment. For comparison purposes, the control group consisted of 6 patients who during phase 2 of their treatment received more aggressive immunosuppressive therapies, but not RTX and IVIg, because the insurance carriers refused to pay for the combination therapy. MAIN OUTCOME MEASURES: Blindness (best-corrected visual acuity [BCVA] < or =20/200) and OCP staging (Foster). RESULTS: The median total follow-up periods were 57.5 and 55.5 months in the control group and the study group, respectively. After phase 1 treatment, all 6 patients in the control group were blind in 1 eye. Similarly, 4 of the patients in the study group were blind in 1 eye, whereas 2 had good BCVA bilaterally but experienced persistent conjunctival inflammation despite phase 1 treatment. After phase 2 treatment, all 6 patients in the control group had OCP progression and became blind in both eyes. In contrast, BCVA was stable and no further progression of OCP staging was observed in all 6 patients in the study group. In the study group, the median follow-up from completion of the RTX and IVIg treatment protocol was 11 months. No adverse events, immediate or delayed, were reported in any of the patients who received the combination therapy of RTX and IVIg. CONCLUSIONS: In this preliminary study, the combination therapy of RTX and IVIg arrested disease progression and prevented total blindness in patients with recalcitrant OCP.

Conjunctivochalasis and contact lenses.

PURPOSE: To assess the relationship between age and the incidence and severity of conjunctivochalasis in contact lens (CL) wearers by grading of conjunctivochalasis, and to compare the severity of conjunctivochalasis between CL wearers and nonwearers. DESIGN: Prospective, nonrandomized consecutive case study. METHODS: A total of 600 CL wearers (94 hard CLs [HCL] and 506 soft CLs [SCL]) aged 11 to 60 years and 579 nonwearers aged 10 to 60 years were enrolled. The age, gender, medical history, ocular history, and the grade and other parameters of conjunctivochalasis at 3 locations (nasal, middle, and temporal areas) were determined in all subjects. RESULTS: The prevalence of conjunctivochalasis increased dramatically with age in all groups. The mean grade of conjunctivochalasis was higher in CL wearers than in nonwearers (nasal area, P < .00001; temporal area, P < .00001) and was higher in HCL wearers than in SCL wearers (nasal area, P < .00001; temporal area, P = .00003). Parameters such as the downward gaze-dependent or digital pressure-dependent changes of conjunctivochalasis and the presence of superficial punctate keratitis all increased with age in both CL wearers and nonwearers. The gaze-dependent and pressure-dependent changes of conjunctivochalasis showed an increase with age and the duration of CL wear in both SCL and HCL wearers. CONCLUSIONS: This was the first assessment of the severity of conjunctivochalasis in a large series of consecutive CL wearers. Our results strongly suggest that wearing CLs is an important risk factor for conjunctivochalasis.

Ocular findings in patients with Crimean-Congo hemorrhagic fever.

PURPOSE: To describe ocular findings of patients with Crimean-Congo hemorrhagic fever (CCHF). DESIGN: Prospective, interventional, consecutive case series. METHODS: This study was conducted in Sivas, a city located in the central Anatolia, between July 1 and August 31, 2007. Confirmed CCHF patients were enrolled in the study and underwent ocular examination during hospitalization. RESULTS: Nineteen confirmed CCHF patients were included in this study. All patients were classified into 2 groups in terms of disease severity (severe vs nonsevere), according to the Swanepoel predictive criteria. Fourteen patients (73.7%) were classified as "nonsevere," and the remaining 5 patients (26.3%) were classified as "severe" in this study. One patient having severe disease died. Ocular findings were present in 14 patients (73.7%) and none of the patients presented any visual complaints. Ocular examination revealed that 7 patients (36.8%) had only bilateral multiple subconjunctival hemorrhage, and 2 patients (10.5%) (1 bilateral, 1 unilateral) had retinal hemorrhage. Five patients (26.3%) had subconjunctival hemorrhage and retinal hemorrhage. Follow-up examination 1 month later showed complete resorption of the subconjunctival hemorrhage and retinal hemorrhage. There was a statistically significant difference between patients with ocular findings and patients without ocular findings for prothrombin time (P = .011). There was no evidence of uveitis, retinal edema, sheathing of retinal vessels, or intravitreal hemorrhage in our patients. CONCLUSION: From the small sample study, CCHF caused a mild form of ocular disease. CCHF must be considered when subconjunctival or superficial retinal hemorrhages are seen in association with fever in endemic areas.
