Role of paranasal abnormalities and systemic inflammation on primary acquired nasolacrimal duct obstruction.

BACKGROUND: To determine the paranasal changes and inflammatory markers that may cause primary acquired nasolacrimal duct obstruction (PANDO) and to determine their relationship with success rates on different types of surgeries. MAIN BODY: We retrospectively reviewed the blood sample and computed tomography (CT) results on 92 patients who underwent dacryocystorhinostomy (DCR) surgery for PANDO and 82 healthy controls. Age, gender, paranasal abnormalities, hemogram values, International Normalized Ratio (INR) values, type of surgery, and recurrence rate were recorded; systemic Immune-inflammation Index (SII), neutrophil-to-lymphocyte ratio (NLR), monocytes-to- lymphocyte ratio (MLR) and platelet-to-lymphocyte ratio (PLR) were calculated in both groups. In the case group, total white blood cells, monocytes, and INR values were significantly lower (p < 0.05). Platelet, lymphocyte, neutrophil, PLR, MLR, NLR, and SII values did not differ significantly between the control and case groups (p > 0.05). There was no significant difference in the CT results between the groups (p > 0.05). No correlation was found between CT findings and inflammatory markers. Dacryocystitis (DC) was seen in 20% of patients and they were all in the case group. No correlation was found between recurrence rate and age, gender, type of surgery, CT findings, and blood results (p > 0.05). The recurrence rate was significantly higher in patients with bilateral PANDO and with DC (p < 0.05). SHORT CONCLUSION: The incidence of PANDO may not be directly related to paranasal abnormalities and systemic inflammation. Low INR values may cause obstruction in the nasolacrimal duct. Age, gender, type of surgery, CT findings, and inflammation level do not affect the success of the surgery.

Characteristics of the retina and choroid in fibromyalgia patients and their correlation with disease severity and quality of life.

BACKGROUND: To evaluate retinal and choroidal characteristics of fibromyalgia (FM) patients using spectral-domain optical coherence tomography (SD-OCT), to compare them with healthy controls, and to determine the correlation of these measurements with disease severity and quality of life. METHODS: Thirty-nine eyes of 39 patients with FM and 44 eyes of 44 age- and sex-matched healthy subjects were enrolled. The retinal nerve fiber layer (RNFL), central macular thickness (CMT), and choroidal thickness (CT) measurements of the subjects were obtained using SD-OCT (Maestro, Topcon Co. Tokyo, Japan), choroidal vascular index (CVI) was calculated by using the binarization method and the results were compared. Disease duration (DD), widespread pain index (WPI), symptom severity scale (SSS), visual analog scale (VAS), ocular pain assessment survey (OPAS), FM impact questionnaire (FIQ), European Quality of Life-5 Dimensions-3 level (EQ-5D-3 L), European Quality VAS score (EQ-VAS) and use of pregabalin were recorded. Correlations between the SD-OCT results and the FM parameters were evaluated. RESULTS: No significant difference was found in terms of age and gender (p = 0.612, p = 0.244 respectively). Patients in the FM group had significantly thinner RNFL superior quadrant and CT (p = 0,009 and p < 0.001, respectively). CVI was significantly higher in the FM group (p < 0.001). There was an inverse correlation between OPAS and CT (r = -0.379, p = 0.027) and between VAS and CVI (r = -0.398, p = 0.020). The use of pregabalin had no effect on SD-OCT (p > 0.05). CONCLUSION: Patients with FM demonstrated reduced RNFL superior quadrant and CT and increased CVI. Ocular and general body pain in FM was found to be associated with SD-OCT.

Investigation of the Relationship Between Cognitive Functions and Retinal Findings From Spectral Optical Coherence Tomography in Patients With Schizophrenia and Their Healthy Siblings.

OBJECTIVE: Retinal structural changes which were investigated by optical coherence tomography (OCT) have been reported in schizophrenia. Since cognitive dysfunction is a core feature of schizophrenia, the correlations between retinal findings and cognitive functions of patients and their healthy siblings may provide insight into the pathophysiological processes of the disorder. We aimed to investigate the relationship between neuropsychiatric tests and retinal changes in schizophrenia patients and their healthy siblings. METHODS: We measured OCT parameters and cognitive performance (via Trail Making Tests, verbal fluency tests, and The Digit Span Tests) of 72 participants (36 patients with schizophrenia and 36 healthy siblings) and disease severity (with Positive and Negative Syndrome Scale, Global Assessment of Functioning, and Clinical Global Impression scales) in patients with schizophrenia and evaluated the relationship between retinal findings and clinical parameters, especially neurocognitive tests. RESULTS: We found decreased ganglion cell layer-inner plexiform layer thickness and macular volume in the patient group. There were strong correlations between neurocognitive tests and OCT findings in both groups. On the other hand, there was not any correlation between retinal findings and disease parameters. CONCLUSION: The cognitive symptoms of schizophrenia may be more closely related to structural changes in the retina.

Retinal changes in bipolar disorder as an endophenotype candidate: Comparison of OCT-detected retinal changes in patients, siblings, and healthy controls.

Optical coherence tomography (OCT) is a non-invasive imaging technique that detects retinal changes reflecting neurodegeneration. In recent studies in patients with bipolar disorder (BD) abnormal OCT findings have shown. In this study, we aimed to investigate the retinal changes in BD patients and their healthy siblings (HS) by comparing them with the healthy control (HC) group and to explore these findings as potential endophenotype candidates. 31 patients with BD, 31 age-matched HSs and 46 HCs were included and peripapillary retinal nerve fiber layer (RNFL), ganglion cell layer (GCL)+inner plexiform layer (IPL) and macular volume (MV) thicknesses were measured by OCT. The relationship between disease severity parameters, functionality and OCT measurements in the patient group was also investigated. In results, the mean RNFL thicknesses did not differ between groups. All GCL+IPL thicknesses were found to be significantly lower in the patient and sibling groups compared to the HCs. GCL+IPL thicknesses were significantly correlated with functionality of patients and severity of the disorder. Our findings suggest that analysis of retinal layers with OCT may be a beneficial indicator to show neuronal changes in BD and GCL+IPL may be a suitable endophenotype candidate.

Comparing retinal changes measured by optical coherence tomography in patients with schizophrenia and their siblings with healthy controls: Are retinal findings potential endophenotype candidates?

AIM: The aim of our study is to examine whether differences in retinal structure may reflect endophenotypes for schizophrenia by comparing thicknesses of retinal layers between patients with schizophrenia, their unaffected siblings, and healthy control groups and investigating the relationship between OCT findings and disease parameters. MATERIAL AND METHODS: 46 patients with schizophrenia, their 46 healthy siblings, and 46 age and gender-matched healthy controls were enrolled in the study and underwent spectral domain OCT (examinations to assess differences in peripapillary retinal nerve fiber layer (RNFL) thickness, ganglion cell layer (GCL)+ inner plexiform layer (IPL) thicknesses and macular volumes (MV) in both eyes). Clinical variables were also recorded in the patient group. RESULTS: There was no difference between the groups in terms of RNFL thicknesses. The GCL+IPL thicknesses of the siblings are between the patients and controls but according to post hoc comparisons the GCL+IPLs of the patients were only thinner than controls. Additionally, MVs were significantly lower in the patient group compared to the sibling group. There was no correlation between any clinical parameters and the GCL+IPLs of all groups, however there were some correlations between RNFL and clinical features especially in the patients group. CONCLUSION: GCL+IPL values do not seem to be affected by the disease parameters or the factors like body mass index or nicotine use. On the other hand, further studies are needed to determine whether GCL+IPL could be an endophenotype candidate.

Periorbital ecchymosis and subconjunctival hemorrhage due to leech therapy for headache / Equimose periorbital e hemorragia subconjuntival devido à terapia com sanguessugas para dor de cabeça

ABSTRACT A 62-year-old woman was admitted to our clinic with the complaints of periorbital ecchymosis and subconjunctival hemorrhage that are visible, especially on the right eye. We noted that her complaints began the day after she underwent leech therapy on the glabella area for headache. On the glabella, 2 leech bites were observed close to the right side. Examination revealed ecchymosis on the bilateral eyelids and subconjunctival hemorrhage on the inferolateral and medial limbus on the right eye. No treatment was initiated, rather control measures were recommended. The follow-up after 1 month revealed that the patient's complaints had disappeared.(AU)

RESUMO Uma paciente de 62 anos procurou nosso ambulatório com queixas de equimose periorbital e hemorragia subconjuntival, visíveis principalmente no olho direito. Descobrimos que suas queixas começaram no dia seguinte a um tratamento para dor de cabeça com sanguessugas na área da glabela. Na glabela, 2 mordidas de sanguessuga foram encontradas próximas ao lado direito. Durante os exames da paciente, foram detectadas equimoses nas pálpebras bilaterais e hemorragia subconjuntival no limbo ínfero lateral e medial do olho direito. Nenhum tratamento foi iniciado, sendo recomendado apenas controle. No acompanhamento, observou-se que as queixas da paciente desapareceram em cerca de um mês.(AU)

Successful correction of ichthyosis-related ectropion by autografts.

Ectropion is a rather frequent complication of ichthyosis with negative functional and esthetic impact. Lid surgery can provide significant improvement. We report on a series of four ichthyosis patients with ongoing bilateral eye problems despite intense medical treatment (mean age 27.8 ± 14.1 years). All patients suffered from lagophthalmos. Two of the patients had only lower lid ectropion. In two of the patients' ectropion was forming on the upper lid in addition to the lower lid when closing the eye. In three of four patients, ectropion was repaired by skin grafts from the supraclavicular region. In a child with lower and upper lid ectropion prepuce was used for repair surgery. At the end of the follow-up period of about 23.0 ± 12.7 months, none of the patients revealed lagophthalmos or corneal exposure. No intraoperative or postoperative complications have been observed in our patients. Ichthyosis patients with ectropion resistant to medical treatment, benefit from surgical treatment with full layer autografts. In boys, prepuce can be successfully used as autograft.

A comparison of two conjunctival rotation autograft techniques in primary pterygium surgery.

PURPOSE: To compare the effects of 90° and 180° conjunctival rotational autograft (CRA) techniques used in primary pterygium surgery. METHODS: Forty-five patients were included in this retrospective study. Visual acuity (VA), corneal topography, and auto-refractometer measurements, as well as detailed biomicroscopic examinations, were performed preoperatively and postoperatively. During surgery, the pterygium tissue was excised then rotated 90° in Group 1 and180° in Group 2, after which it was sutured to the bare sclera. Pterygium recurrence was defined as corneal invasion ≥1 mm. RESULTS: Group 1 consisted of 21 patients with a mean age of 45.1 ± 11.8 years, while Group 2 comprised 24 patients with a mean age of 47.9 ± 13.8 years. The pterygia in Group 1 were graded as more advanced than those in Group 2. A similar number of recurrences were observed in Group 1 (14.3%) and in Group 2 (16.7%). There was no statistically significant difference in terms of the preoperative and postoperative VA and astigmatism values between the two groups. There was a statistically significant improvement in the postoperative VA and astigmatism values in Group 1 and in the postoperative astigmatism values in Group 2. Although postoperative redness was more common in Group 1, no statistically significant difference was found between the groups. CONCLUSION: BothCRA techniques can be successful in patients for whom it is desirable to avoid a conjunctival autograft and for patients without high cosmetic expectations.

RESUMO Objetivo: Comparar os efeitos das técnicas de auto-enxerto rotacional de conjuntiva (CRA) de 90° e 180°, usadas na cirurgia de pterígio primário. Métodos: Quarenta e cinco pacientes foram incluídos neste estudo retrospectivo. Acuidade visual (AV) pré e pós-operatória, topografia da córnea, auto-refratometria e exames biomicroscópicos detalhados foram feitos. Durante a cirurgia, o tecido de pterígio foi excisado e o mesmo tecido foi girado 90° no Grupo 1 e 180° no Grupo 2, após o que foi suturado à esclera nua. A recorrência do pterígio foi definida como invasão da córnea ≥1 mm. Resultados: O Grupo 1 consistiu em 21 pacientes, cuja média de idade foi de 45,1 ± 11,8 anos e o Grupo 2 compreendeu 24 pacientes, cuja idade média foi de 47,9 ± 13,8 anos. O Grupo 1 teve maior frequência de pterígios classificados como mais avançada do que no Grupo 2. Um número similar de recorrências foi observado no Grupo 1 (14,3%) e no Grupo 2 (16,7%). Não houve diferença estatisticamente significativa em termos de valores pré e pós-operatórios de AV e astigmatismo entre dois grupos. Houve uma melhora estatisticamente significativa nos valores pós-operatórios de AV e astigmatismo no Grupo 1 e nos valores de astigmatismo pós-operatório no Grupo 2. Embora a vermelhidão pós-operatória tenha sido detectada mais comumente no Grupo 1, não foi encontrada diferença estatisticamente significante entre os grupos. Conclusão: Ambas as técnicas de CRA podem ser bem sucedidas em pacientes onde é desejável evitar um auto-enxerto conjuntival livre e para quem a expectativa de cosméticos não é alta.

The Efficacy and Safety of Intravitreal Dexamethasone Implant for the Treatment of Macular Edema Related to Retinal Vein Occlusion: Real-life Data and Prognostic Factors in a Turkish Population.

OBJECTIVES: To evaluate the efficacy and safety of dexamethasone (DEX) implants as mono or combination therapy for macular edema in retinal vein occlusion (RVO) with real-life conditions, and to detect factors that influence final visual acuity. MATERIALS AND METHODS: Twenty-five eyes with macular edema secondary to RVO underwent assessments for central macular thickness (CMT), best-corrected visual acuity (BCVA), adverse events, and also morphologic changes in optical coherence tomography at an interval of 4-8 weeks after at least one DEX implant. RESULTS: Seventeen eyes with branch RVO and 8 eyes with central RVO were eligible for the study. The mean follow-up duration was 17 months (range, 12-26 months). Both mean BCVA (p=0.009) and CMT (p=0.006) improved significantly, and visual gains of ≥3 lines were achieved in 32% and ≥2 lines in 52% at the end of the follow-up period. The most powerful individual predictor of final visual acuity was baseline BCVA (r2=0.611, p<0.001, stepwise multiple regression), but the most efficient model was the combination of the ellipsoid zone (EZ) integrity and baseline BCVA (r2=0.766, p<0.001, stepwise multiple regression). Complication rates were very low after repeated DEX implants. CONCLUSION: DEX implant seems to be an effective and safe treatment for macular edema in RVO despite negative real-life factors, and visual outcomes are associated with baseline visual acuity and EZ integrity.

Ocular surface findings in patients with rheumatoid arthritis under methotrexate or biological agent therapy.

PURPOSE: To evaluate the ocular findings in patients with rheumatoid arthritis (RA) treated with disease-modifying antirheumatic drugs (DMARDs) such as methotrexate (MTX) or MTX with biological agents. METHODS: One hundred and twelve eyes of 56 patients with RA and treated with MTX or MTX with biological agents were included in the study. Patients were divided into two groups using DMARDs only (group 1) and patients using DMARDs and biologic agents together (group 2). In both groups; Schirmer's II test, tear film break-up time (tBUT), central corneal thickness (CCT), corneal volume (CV), intraocular pressure (IOP) measurement, and anterior segment and fundus examinations of the eye with slit lamp were carried out. Ocular surface disease index (OSDI) score questionnaire were performed. RESULTS: Thirty-eight patients with a mean age of 53.00 ± 8.19 years were in group 1 and 18 patients with a mean age of 51.00 ± 9.54 years were in group 2. The mean duration of RA was 6.89 ± 7.96 years in group 1 and 5.70 ± 9.00 years in group 2. There was a statistically significant difference between two groups with tBUT, CCT, CV, IOP (p < 0.05) and there was no significant difference with age, sex, disease duration, disease activity, and Schirmer's II test (p > 0.05). The disease duration showed a significant moderate negative correlation with CCT and CV in group 2 (p < 0.05). CONCLUSIONS: Although tBUT values were significantly higher in the combination treatment group, CCT and CV values were significantly lower. Due to the decrease in corneal thickness, IOP was determined to be significantly lower.

Toxic anterior segment syndrome following deep anterior lamellar keratoplasty.

We present the case of a 31-year-old patient with toxic anterior segment syndrome (TASS) that developed after undergoing deep anterior lamellar keratoplasty (DALK). She had keratoconus, and despite wearing hard contact lenses for many years in the left eye, her vision had deteriorated; therefore, DALK was performed on this eye. The preoperative visual acuity (VA) was finger counting at 3 m. Routine DALK was performed using the "big-bubble" technique. The corneal entry incision was hydrated at the end of the surgery, which was terminated by air injection into the anterior chamber. On postoperative day 1, VA was at the level of hand movements, and the cornea was edematous. Topical high-dose dexamethasone and oral steroids were initiated considering the diagnosis of TASS. Subsequently, the patient's VA increased, and the corneal edema decreased. We believe that the use of re-sterilized cannulas may have been the likely cause of TASS. Although DALK can be performed without interfering with the anterior chamber, one should keep in mind that TASS may occur in response to the solution used to hydrate the incision site and the air injected into the anterior chamber.

RESUMO Apresentamos o relato de uma paciente com 31 anos de idade, que desenvolveu síndrome tóxica do segmento anterior (TASS) após o procedimento de transplante lamelar anterior profundo (DALK). Ela apresentava ceratocone e, apesar de ter usado lentes de contato rígidas por muitos anos no olho esquerdo, apresentou deterioração da visão nesse olho que foi submetido a procedimento DALK. A acuidade visual (VA) era de conta dedos a três metros. O procedimento DALK de rotina foi realizado utilizando técnica de bolha grande (Big Bubble). A incisão de entrada da córnea foi hidratada ao final da cirurgia que foi terminada com a injeção de ar na câmara anterior. No primeiro dia de pós-operatório a VA era de percepção de movimentos da mão e a córnea estava edemaciada. Dexametasona tópica em alta dose e esteróides orais foram iniciadas ao se considerar o diagnóstico de TASS. Acreditamos que o uso de cânulas reesterilizadas podem ter sido a causa provável da TASS. A VA melhorou e o edema da córnea do diminuiu durante a evolução. Embora o procedimento DALK foi realizado sem interferir com câmara anterior, deve-se ter em mente que TASS pode ocorrer com a solução utilizada para hidratar o local da incisão e o ar injetado na câmara anterior.

External ophthalmomyiasis seen in a patient from Istanbul, Turkey.

Ophthalmomyiasis externa, results from infestation of the conjunctiva by the larval form of Oestrus ovis. It is usually seen in rural areas. We report a case with ophthalmomyiasis externa in a young man living in an urban area (Istanbul, Turkey) who had no known history of traveling to the rural area. Even in patients living in urban areas ophthalmomyiasis externa should be taken into consideration in differential diagnosis of red eye.
