A case of choroidal neovascularization as a first manifestaion of systemic lupus erythematosus.

BACKGROUND: To report a rare occurrence of pigment epitheliopathy associated with choroidal neovasculization as a first manifestation of systemic lupus erythematosus. CASE PRESENTATION: A 54-year-old female, with no prior medical history, sought a second opinion due to sudden drop in vision in her right eye to 20/80. Slit lamp examination was normal. Fundus examination revealed the presence of a subretinal hemorrhage in the macular area. Fundus imaging including optical coherence tomography and fluorescein angiography showed multifocal retinal pigment epitheliopathy associated with choroidal neovascularization (CNV). The patient had received an intravitreal injection of Bevacizumab 2 weeks ago. It was decided to complete the loading dose regimen with two additional Bevacizumab injections, and the first injection was done 2 weeks after her presentation. Two weeks later, the patient reported a rash on her cheeks, painful joints, and purpura. Systemic workup revealed positive ANA, anti-cardiolipin antibodies, and decreased complement levels, with negative anti-histone antibodies. This led to the diagnosis of systemic lupus erythematosus (SLE) based on the "Systemic Lupus International Collaborating Clinics" criteria. The patient was treated with 50 mg of prednisolone which was then tapered. 1 month after the third injection, an showed a total resolution of the sub-retinal fluid with an improvement of vision to 20/20. No recurrence was observed during follow-up. CONCLUSION: Based on the findings from the fundus exam and imaging, systemic symptoms and the blood work-up, we postulate that the pigment epitheliopathy associated with choroidal neovascularization was related to the vaso-occlusive disease at the level of the choroid that can be part of SLE vasculopathy. To our knowledge, this represents the first case in which pigment epitheliopathy and CNV were the primary manifestations of SLE.

Safety, Efficacy, and Predictive Factors of Conventional Epithelium-Off Corneal Crosslinking in the Treatment of Progressive Keratoconus.

PURPOSE: To report predictive factors of outcome of conventional epithelium-off corneal crosslinking (CXL) in the treatment of progressive keratoconus. METHODS: This is a monocentric observational retrospective study conducted at Eye and Ear International Hospital, Lebanon. All patients with progressive keratoconus who underwent CXL between January 2008 and January 2016, with minimal 3-years follow-up were included. Primary treatment outcomes were maximum keratometry (K max), best-corrected distance visual acuity (CDVA), and failure. Failure was defined as an increase of 1.00 diopters (D) or more in K max and/or an increase of 0.1 logMAR or more in CDVA and conversion to corneal transplantation. Statistical analysis was done to identify predictors of treatment success. Univariate and multivariate analyses were performed to determine the correlations between baseline parameters and outcomes, and an equation for predicting K max and CDVA was created. RESULTS: 156 eyes of 102 patients were enrolled. The mean age was 23.85 ± 6.52 years. Failure occurred in 31 eyes (19.87%). Gender and thinnest pachymetry did not have any impact on postoperative outcomes. Concerning the CDVA outcome, multivariate analysis showed that a better preoperative CDVA was associated with higher improvement in CDVA, and higher baseline K max and higher posterior mean K were associated with a worse outcome CDVA. Regarding postoperative K max, a higher baseline K max, a worse baseline CDVA, and a younger age were associated with less flattening postoperatively. CONCLUSION: CXL is a safe and effective method in treating progressive keratoconus. However, the clinical benefits can differ among patients, and in our series, a nonnegligible number of cases show a continued progression of their ectasia. Further studies to identify predictors of postoperative progression prior to the procedure could help sort out good responders to treatment.

Comparison of Efficacy and Ocular Surface Disease Index Score between Bimatoprost, Latanoprost, Travoprost, and Tafluprost in Glaucoma Patients.

AIM: The purpose of this study is to evaluate and compare the efficacy of 4 prostaglandin analogues (PGAs) and to determine the incidence of ocular surface disease in newly diagnosed, primary open-angle glaucoma (POAG) patients started on one of those 4 PGAs: bimatoprost (benzalkonium chloride, BAK, 0.3 mg/mL), latanoprost (BAK 0.2 mg/mL), travoprost (polyquad), and tafluprost (BAK-free). PATIENTS AND METHODS: In this single-center, open-label trial, 32 patients newly diagnosed with POAG were randomly started on one of the four PGAs. All patients underwent a complete ophthalmological exam at presentation and at 1, 3, and 6 months of follow-up. Dry eye disease (DED) was assessed using the original Ocular Surface Disease Index (OSDI) questionnaire, in order to evaluate the impact of the drops on the quality of life of patients. RESULTS: The mean age was 60.06 years ± 11.76. All four drugs equally and significantly reduced the intraocular pressure (IOP) with respect to the baseline IOP. There was a trend for a slightly greater reduction of IOP with bimatoprost, but the difference was not found to be statistically significant when compared to other PGAs. OSDI scores were significantly superior for travoprost (10.68 ± 5.73) compared to the other three drugs (p < 0.05). Latanoprost caused the most significant eyelash growth and iris discoloration. Conjunctival hyperemia and superficial keratitis occurrence were similar in the four groups. CONCLUSION: All prostaglandin analogues equally and significantly reduce the IOP in patients with POAG. According to the results of the OSDI score, latanoprost seems to be the least tolerated among the four drugs.

Evaluation of allergic sensitization in Lebanese patients with allergic conjunctivitis.

PURPOSE: To describe the profile of patients with allergic conjunctivitis (AC) regarding their demographics, symptomatology and specific allergen sensitization, in a Lebanese tertiary hospital. METHODS: Cross-sectional study conducted at the Hôtel-Dieu de France hospital (Beirut, Lebanon) during a period of 18 months. Patients with seasonal or perennial AC presenting for ophthalmic consultation had measurements of total and specific IgE. A matching group of patients with AC seen at the allergist office during the same period underwent skin prick tests (SPTs). RESULTS: Forty-four patients were enrolled for blood work by their ophthalmologists. Seasonal and perennial forms were almost equivalent. In total, 56.8% had positive specific IgE, with higher prevalence in patients with seasonal AC (p = 0.002), other associated allergies particularly allergic rhinitis (p = 0.002) or a family history of allergy (p = 0.005). Ocular surface severity scales were not shown as predictors. High levels of total IgE were commonly detected in those with positive specific IgE. Thirty-eight patients were assessed with SPT, and all had a positive result for at least one allergen. Dust mites were found to be the most frequent allergens based upon both specific IgE (72%) and SPT (92%), followed by Parietaria and other pollens. CONCLUSION: In our study, dust mites mono- or co-sensitization is present in the majority of patients with AC, with odds of positivity being higher using SPT than specific IgE. The latter are found more readily in seasonal AC and in the presence of personal and family history of allergy.

VITREORETINAL SURGERY WITH SILICONE OIL TAMPONADE IN PRIMARY UNCOMPLICATED RHEGMATOGENOUS RETINAL DETACHMENT: Clinical Outcomes and Complications.

BACKGROUND: To determine the anatomical and functional outcomes and possible complications after pars plana vitrectomy (PPV) with silicone oil (SO) tamponade in primary uncomplicated rhegmatogenous retinal detachments. METHODS: This is a prospective observational study. Overall, 62 consecutive patients who underwent surgical repair by PPV and SO injection for primary uncomplicated rhegmatogenous retinal detachment between January 01, 2006 and April 30, 2012 were followed. In general, PPV was chosen over scleral buckling when a significant cataract or a vitreous hemorrhage prevented adequate fundus visualization. Silicone oil was chosen over gas tamponade in patients living at 1,000 meters above the sea level, where SF6 or C3F8 tamponade could not be performed because of the risk of acute increase of intraocular pressure (IOP). One thousand centistokes SO was used in all eyes. At all visits, patients had a detailed ocular history and thorough bilateral evaluation, including best-corrected visual acuity, anterior segment examination, and IOP measurements by aplanation and fundus examination. Outcomes were assessed at 1 day, 1 week, 1 month, 3 months, 6 months, and every 6 months thereafter. Increased IOP was defined as an IOP of more than 21 mmHg. RESULTS: Anatomical success rate, final best-corrected visual acuity, IOP elevation, cataract formation, and other complications were the main outcome measures. This study included 62 eyes of 62 patients (41 men and 21 women) that underwent retinal detachment repair by PPV and SO injection. The age at the time of intervention was 57.6 ± 10.5 years (mean ± standard deviation; range, 34-79 years). All patients were whites. Mean follow-up was 24.5 ± 17.3 months (range, 6-70 months). Anatomical success rate defined as retinal reattachment 6 months after SO removal was 93.5%. Final BCVA was improved in 55 eyes (88.7%), with a mean of 4 Snellen lines, unchanged in 5 (8.1%), and worse in 2 eyes (3.2%), with a mean of 3 Snellen lines. Mean duration of SO tamponade was 5.12 ± 2.37 months (range, 2-12 months). From the 30 eyes that were still phakic after vitrectomy, 24 eyes (80.0%) underwent cataract surgery within a period of 7.37 ± 3.00 months (range, 2-13 months). Thirty-five eyes (56.5%) had an increase in IOP during the follow-up period. Thirty-one patients had transient ocular hypertension requiring topical treatment during the immediate postoperative period (one month). Only 1 eye (2.9%) required filtrating drainage surgery for IOP control. No eyes developed optic neuropathy secondary to IOP elevation. CONCLUSION: Pars plana vitrectomy with SO injection seems to be a safe and efficient surgical approach in the treatment of primary uncomplicated rhegmatogenous retinal detachment in patients living in high altitude (>1,000 m). Also, PPV and SO injection are associated with good anatomical and functional outcomes in our series. Reattachment rates are high, and rates of proliferative vitreoretinopathy are low. Cataract formation and elevated IOP represent frequent but successfully controlled complications.

The dacryoscanner, an optimal technique for nasolacrimal system exploration. / Le dacryoscanner, une technique optimale d'exploration des voies lacrymo-nasales.

The dacryoscanner is the imaging technique of choice in case of persistent tearing. It allows the opacification of nasolacrimal system, and thus determines the site and the origin of obstruction. The site could be the lacrimal canaliculus, the lacrimal sac, or the nasolacrimal duct. The origin could be an idiopathic or a sequellar stenosis, a dacryolithiases, a bony malformation, or a tumor. This is a technique done by the radiologist under aseptic conditions, and easily tolerated by the patient. Many technical variants exist for an optimal opacification of the nasolacrimal system.

Complete Disappearance of Choroidal Metastasis from Lung Adenocarcinoma Treated with Bevacizumab and Chemotherapy.

Choroidal metastasis from lung cancer is uncommon. We report a case of choroidal metastasis as an inaugural manifestation of lung adenocarcinoma, successfully treated by docetaxel, cisplatinum, and intravenous bevacizumab as an antiangiogenesis therapy. A complete remission was obtained after 4 cycles and maintained after six cycles. This case report demonstrates the importance of the systemic bevacizumab and chemotherapy in the treatment of choroidal metastasis from adenocarcinoma of the lung.

Intravitreal bevacizumab in the management of neovascular age-related macular degeneration: effect of baseline visual acuity.

PURPOSE: To study prospectively the safety and efficacy of intravitreal bevacizumab for eyes with neovascular age-related macular degeneration with baseline visual acuity better than 70 letters (Snellen equivalent better than 20/40). METHODS: Patients with treatment-naive neovascular age-related macular degeneration were categorized prospectively into three groups according to baseline visual acuity: Group 1 (better than 70 letters), Group 2 (70 to 61 letters), and Group 3 (60 to 51 letters). Best-corrected visual acuity and central retinal thickness using optical coherence tomography were measured at baseline and at each follow-up visit. Intravitreal bevacizumab was administered according to an as-needed optical coherence tomography-guided regimen. Main outcome measure was mean best-corrected visual acuity for each group at 12 months. RESULTS: Each group included 30 patients (30 eyes). Improvement in central retinal thickness was similar among the 3 groups (P = 0.964). Mean letter gain in visual acuity at 12 months was +0.4, +3.8, and +4.2 for Groups 1, 2, and 3, respectively (P = 0.42). Mean best-corrected visual acuity at 12 months was 78.4 letters for Group 1, 70.0 letters for Group 2, and 61.1 letters for Group 3 (P < 0.001). All eyes in Group 1 (100%) avoided losing 15 letters of best-corrected visual acuity versus 83.3% in Group 2 and 80.0% in Group 3. This difference was significant only between Group 1 and Group 3 (P = 0.02). CONCLUSION: Intravitreal bevacizumab for eyes with neovascular age-related macular degeneration and baseline visual acuity better than 70 letters was safe and able to maintain this vision over 12 months.

Fixed-interval versus OCT-guided variable dosing of intravitreal bevacizumab in the management of neovascular age-related macular degeneration: a 12-month randomized prospective study.

PURPOSE: To compare the efficacy of as-needed or variable dosing of intravitreal bevacizumab to continuous fixed-interval dosing in the management of neovascular age-related macular degeneration (AMD). DESIGN: Prospective, open-label, randomized clinical study. METHODS: One hundred twenty eyes of 120 patients with treatment-naïve subfoveal neovascular AMD participated in this study at the American University of Beirut and Hotel Dieu de France Retina Clinics. Eyes were randomized (1:1) to fixed-interval dosing (every 4 to 6 weeks) or variable dosing with intravitreal bevacizumab (1.25 mg/0.05 mL). Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) using optical coherence tomography (OCT) were measured at baseline and at each follow-up visit. Presence or recurrence of fluid on OCT was the main indicator for retreatment in variable dosing. Main outcome measure was improvement in BCVA and CRT at 12 months. RESULTS: Compared to baseline, variable dosing had a mean improvement in BCVA of 11.0 letters after 12 months vs 9.2 letters for fixed-interval dosing (P = .81). Similarly, CRT decreased after 12 months by 80.7 µm for variable dosing vs 100.5 µm for fixed-interval dosing (P = .37). The average number of injections over 12 months was higher for fixed-interval dosing than variable dosing (9.5 vs 3.8 injections, P < .001). CONCLUSIONS: Fixed-interval and variable dosing regimens of intravitreal bevacizumab improved visual acuity and anatomic outcomes after 12 months in eyes with neovascular AMD. However, variable dosing had a reduced treatment burden. Larger trials are needed to confirm these results.

Intravitreal bevacizumab for treatment of neovascular age-related macular degeneration: the second year of a prospective study.

PURPOSE: To demonstrate the efficacy of intravitreal bevacizumab for treatment of neovascular age-related macular degeneration (AMD). DESIGN: Prospective, open-label, nonrandomized clinical study. METHODS: Fifty-one patients (51 eyes) with subfoveal choroidal neovascularization (CNV) resulting from AMD participated in this study at the American University of Beirut and Hotel Dieu de France Retina Clinics. These patients had already completed 12 months of follow-up. The criteria for reinjection were presence of fluid in the macula, increased central retinal thickness (CRT) of at least 100 microm, loss of at least 5 letters of vision associated with increased fluid in the macula, new classic CNV, or new macular hemorrhage. The main outcome measure was the proportion of eyes losing fewer than 15 letters of vision after 12 months. RESULTS: Fifty-one patients (51 eyes) completed the additional 12 months. Mean visual acuity improved from 45.7 letters at baseline to 54.3 letters at 24 months (P = .001), and 47 eyes (92.2%) lost fewer than 15 letters. Mean CRT decreased from 327.4 microm at baseline to 246.6 mum at 24 months (P < .001). A mean of 1.5 injections were administered over the course of the second year. No serious ocular or systemic side effects were noted. CONCLUSIONS: Eyes with neovascular AMD treated with intravitreal bevacizumab over 2 years had significant anatomic and functional improvement compared with baseline. Further studies are necessary to confirm the long-term efficacy and safety of this treatment.

Intravitreal triamcinolone acetonide: Pattern of secondary intraocular pressure rise and possible risk factors.

PURPOSE: To determine the pattern of increase in intraocular pressure (IOP) following intravitreal triamcinolone acetonide (IVTA) and identify possible risk factors associated with this rise in IOP. METHODS: We carried out a retrospective review of records for 185 patients (226 eyes) who received 4 mg of IVTA at the American University of Beirut Medical Center and Hotel Dieu de France eye clinics between 2003 and 2005 RESULTS: Mean follow-up was 8.17 months (range 6 to 24 months). The mean number of IVTA injections per eye was 1.31 +/- 0.69. The mean IOP increased after the first IVTA injection from 15.04 +/- 3.18 mmHg at baseline to a mean maximum of 17.20 +/- 5.75 mmHg (p < 0.0001, paired t-test) at month 3 of follow-up with a return to mean baseline IOP (15.49 +/- 4.79 mmHg) at month 12. Fifty nine of 226 eyes showed IOP higher than 21 mmHg during follow-up. Nine eyes started to have IOP greater than 21 mmHg, 6 to 12 months after a single injection. Intraocular pressure lowering medications were started when IOP exceeded 25 mmHg in 15 of the 226 eyes studied. No risk factors have been found to predict this IOP rise CONCLUSIONS: IOP elevation can occur in a significant number of eyes receiving 4 mg of IVTA. This phenomenon seems to be transient and a small number of eyes required treatment during this period. Eyes that received IVTA need to be monitored for IOP changes especially during the first 3 months, but the IOP may still rise 6 months and even 12 months after a single injection. This study did not show any risk factor that may predict this IOP rise.

Intravitreal bevacizumab for treatment of neovascular age-related macular degeneration: a one-year prospective study.

PURPOSE: To investigate the efficacy of intravitreal bevacizumab for treatment of neovascular age-related macular degeneration (AMD). DESIGN: Prospective, open-label, nonrandomized clinical study. METHODS: Sixty patients (60 eyes) with subfoveal choroidal neovascular membrane (CNV) attributable to AMD participated in this study at the American University of Beirut and Hotel Dieu de France Retina Clinics. All lesion types were included except for retinal angiomatous proliferation. In the initial treatment phase, intravitreal bevacizumab (2.5 mg/0.1 ml) was given at baseline, and then two additional monthly injections were given if the macula was not dry on optical coherence tomography. The criteria for re-injection after the induction phase were presence of new fluid in the macula, increased central retinal thickness (CRT) at least 100 microm, loss of at least five letters of vision with increased fluid in the macula, new classic CNV or new macular hemorrhages. Main outcome measure was the proportion of eyes losing <15 letters of vision after 12 months. RESULTS: Fifty-one patients (51 eyes) completed the 12 months. Mean visual acuity improved from 45.7 letters at baseline to 53.1 letters at 12 months (P = .004), and 47 eyes (92.2%) lost <15 letters. Mean CRT decreased from 327.4 microm at baseline to 227.8 microm at 12 months (P < .001). A mean of 3.4 injections were given over the course of the study, and no ocular or systemic side-effects were noted. CONCLUSION: Eyes with neovascular AMD treated with intravitreal bevacizumab over 12 months had significant anatomical and functional improvement. Further studies need to confirm the long-term efficacy of this treatment.

Intravitreal bevacizumab vs verteporfin photodynamic therapy for neovascular age-related macular degeneration.

OBJECTIVE: To compare verteporfin photodynamic therapy (PDT) with intravitreal bevacizumab for management of choroidal neovascularization (CNV) associated with age-related macular degeneration. METHODS: Patients with predominantly classic CNV were prospectively randomized to receive standard PDT or intravitreal bevacizumab injections (2.5 mg). Best-corrected visual acuity (BCVA) measured by Snellen charts, central retinal thickness by optical coherence tomography, and greatest linear dimension of the CNV by fluorescein angiography were compared between the groups at baseline and at 3 and 6 months. Main outcome measures were stability or improvement in BCVA, decrease in central retinal thickness, and stability in greatest linear dimension. RESULTS: Mean baseline BCVA, central retinal thickness, and greatest linear dimension were not statistically different between the bevacizumab (n = 32) and PDT (n = 30) groups. Mean central retinal thickness was significantly better at 3 and 6 months in the bevacizumab group vs the PDT group (P = .04 and P = .002, respectively). At 3 months, mean BCVA and greatest linear dimension were not significantly different between the 2 groups. At 6 months, mean BCVA and greatest linear dimension were significantly better in the bevacizumab group (P < .001 and P = .02, respectively). CONCLUSION: During 6 months, intravitreal bevacizumab was superior to PDT in controlling predominantly classic CNV in age-related macular degeneration. Additional randomized clinical trials are necessary to determine if this benefit will remain with longer follow-up.

Intravitreal bevacizumab for the management of choroidal neovascularization in age-related macular degeneration.

PURPOSE: To investigate the efficacy and safety of intravitreal bevacizumab for managing choroidal neovascularization (CNV) due to age-related macular degeneration (AMD). DESIGN: Prospective interventional case series. METHODS: Seventeen eyes of 17 patients with subfoveal CNV due to AMD participated in this study at the American University of Beirut Ophthalmology Clinics. All patients had failed, refused, or were not eligible for photodynamic therapy. All eyes received a baseline eye examination, which included best-corrected visual acuity (BCVA), dilated fundus examination, ocular coherence tomography (OCT) imaging, and fluorescein angiography. An intravitreal injection of bevacizumab (2.5 mg/0.1 ml) was given at baseline and followed by two additional injections at four-week intervals. BCVA, OCT, and fluorescein angiography were repeated four weeks after each injection. Main outcome measures were improvement in BCVA and central retinal thickness (CRT). RESULTS: Mean baseline BCVA was 20/252 (median 20/200), and baseline CRT was 362 microm (median 350 microm). Improvement in VA and CRT occurred by the fourth week. At 12 weeks, mean BCVA was 20/76 (P < .001) and median BCVA was 20/50 (P < .001). Both mean and median CRT decreased to 211 microm (P < .001). Thirteen (76%) of 17 eyes had total resolution of subretinal fluid, and four eyes (24%) had BCVA better than 20/50. No systemic or ocular side effects were noted at any time. CONCLUSION: Eyes with CNV due to AMD treated with intravitreal bevacizumab had marked anatomic and visual improvement. Further studies are necessary to confirm the long-term efficacy and safety of this treatment.

Panretinal photocoagulation and intravitreal triamcinolone acetonide for the management of proliferative diabetic retinopathy with macular edema.

PURPOSE: To investigate intravitreal triamcinolone acetonide (IVTA) as an adjunctive therapy to panretinal photocoagulation (PRP) in patients with both high-risk proliferative diabetic retinopathy (PDR) and clinically significant macular edema (CSME). METHODS: Thirty-five eyes diagnosed with both high-risk PDR and CSME underwent PRP and a single injection of 4 mg of IVTA (IVTA group). Visual, anatomic, and fluorescein angiographic changes were documented. Any complications resulting from the combined procedure were noted. These data were compared retrospectively to 35 eyes that underwent grid laser treatment to the macula followed 2 weeks later by PRP (laser group). Main outcome measures included change in best-corrected visual acuity, improvement in macular edema (clinical or angiographic), and control of the neovascular disease. RESULTS: Mean follow-up was 9.6 months for the IVTA group and 11.9 months for the laser group. Mean pretreatment best-corrected visual acuity was 20/286 in the IVTA group and 20/282 in the laser group (P = 0.80). After 9 months of follow-up, visual acuity was 20/80 in the IVTA group versus 20/156 in the laser group (P = 0.007). Thirty-four percent of eyes in the IVTA group had final vision of 20/40 or better versus 11% in the laser group (P = 0.044). At 9 months follow-up, 84% of IVTA eyes had complete resolution of macular edema versus 46% of laser eyes (P = 0.002). Three eyes in the IVTA group had recurrence of macular edema after 6 months and required reinjection of IVTA. Elevation in intraocular pressure occurred in eight eyes in the IVTA group and responded to topical therapy. Cataract progression was observed in nine eyes in the IVTA group. CONCLUSIONS: The addition of intravitreal triamcinolone acetonide to PRP in the management of patients with both PDR and CSME seems promising. Further study is needed to assess the effect of this combined treatment.
