ABSTRACT
Importance: Ulceration is a common complication of infantile hemangioma (IH), which leads to substantial morbidity. Ulceration in IH has not been systematically studied since the advent of ß-blocker therapy for IH. Objectives: To examine treatment interventions used for ulceration in IH and identify clinical prognostic indicators of healing time. Design, Setting, and Participants: A retrospective, multicenter cohort study was conducted on 436 consecutive patients with a clinical diagnosis of ulcerated IH and available clinical photographs. Patients receiving care at tertiary referral centers evaluated between 2012 and 2016 were included; statistical and data analysis were performed from February 7 to April 27, 2020. Exposures: Clinical characteristics, treatment interventions, course, complications, and resource use were analyzed. Treatment interventions for ulceration in IH included local (wound care, topical), systemic (ß-blocker, corticosteroids), and procedural (pulsed-dye laser). Main Outcomes and Measures: The primary end point was time to complete or nearly complete ulceration healing. Clinical characteristics were analyzed to determine the responses to most common interventions and prognostic factors for healing of ulceration. Results: Of the 436 patients included in the study, 327 were girls (75.0%); median age at ulceration was 13.7 weeks (interquartile range, 8.86-21.30 weeks). The median heal time was 4.79 weeks (95% CI, 3.71-5.86 weeks) with wound care alone, 5.14 weeks (95% CI, 4.57-6.00 weeks) with timolol, 6.36 weeks (95% CI, 5.57-8.00 weeks) with a systemic ß-blocker, and 7.71 weeks (95% CI, 6.71-10.14 weeks) with multimodal therapy. After adjusting for IH size, a dose of propranolol less than or equal to 1 mg/kg/d was associated with shorter healing time compared with higher propranolol doses (hazard ratio, 2.04; 95% CI, 1.11 to 3.73; P = .02). Size of the IH was identified as a significant prognostic factor for healing time in multivariable analysis. Increasing size of IH portends a proportionately longer time to heal of the ulceration. Conclusions and Relevance: Despite the use of ß-blockers, this cohort study found that a subset of patients with IH ulceration continued to experience prolonged IH healing times. Larger IH size appears to be a poor prognostic factor for time to heal. For patients requiring systemic therapy, initiation of propranolol at lower doses (≤1 mg/kg/d) should be considered.

Resumo A reversão da escavação é uma entidade rara que se refere à redução da escavação do disco óptico em resposta à diminuição sustentada dos níveis de pressão intra-ocular (PIO), em cerca de 25% da PIO basal. A ocorrência deste fenômeno apenas com o tratamento clínico é pouco relatada na literatura, Este estudo relata um caso de um paciente com glaucoma juvenil, que apresentou à gonioscopia ângulo aberto e tomografia de coerência óptica (OCT) com uma diminuição significativa na camada de fibras nervosas retinianas em ambos os olhos. Após um ano utilizando análogos de prostaglandina tópica e manutenção de níveis baixos de PIO, ocorreu diminuição da escavação do nervo óptico, que foi confirmada pelos padrões topográficos da OCT. O "reversal of cupping" é um sinal da diminuição da tensão ao nível da lâmina crivosa e está provavelmente associada a uma redução do risco para a progressão do glaucoma a longo prazo, sem melhora da função visual.
Abstract Reversal of cupping is a rare entity, characterized by the reduction of optical disc cupping in response to sustained decrease in intraocular pressure (IOP) levels by 25% of the basal IOP. The occurrence of this phenomenon with clinical treatment is rarely reported in the literature. This study reports a case of a patient with juvenile glaucoma with augmented cupping, significant decrease in the retinal nerve fiber layer in both eyes and altered topografic measures in optical coherence tomography (OCT). After one year using topical prostaglandin analog and keeping low IOP levels, a decrease in optic nerve cupping was detected in rethinography, confirmed by the improvement of OCT topographic measures. Reversal of cupping is a sign of decreased tension at the level of the lamina cribosa and is probably associated with a reduced risk for long-term progression of glaucoma without improvement of visual function.

The purpose of this study was to evaluate the neuroprotective effects of omega-3 polyunsaturated fatty acid (ω3-PUFA) supplementation, alone or in combination with timolol eye drops, in a mouse model of hereditary glaucoma. DBA/2J mice (8.5-month-old) were assigned to an ω3-PUFAs + timolol, ω3-PUFAs only, timolol only, or an untreated group. Treated mice received a daily gavage administration of eicosapentaenoic acid (EPA) and docosahexaenoic acid and/or topical instillation of timolol (0.5%) once a day for 3 months. Blood was analysed regularly to determine ω3-PUFA levels and retinas were histologically analysed. Real-time PCR and Western blot were performed for retinal pro-inflammatory cytokines and macrophages. Blood arachidonic acid/EPA ratio gradually decreased and reached the desired therapeutic range (1-1.5) after 4 weeks of daily gavage with ω3-PUFAs in the ω3-PUFAs + timolol and ω3-PUFAs only groups. Retinal ganglion cell densities were significantly higher in the ω3-PUFAs + timolol (1303.77 ± 139.62/mm2), ω3-PUFAs only (768.40⯱â¯52.44/mm2) and timolol only (910.57⯱â¯57.28/mm2) groups than in the untreated group (323.39⯱â¯95.18/mm2). ω3-PUFA supplementation alone or timolol alone, significantly increased protein expression levels of M1 macrophage-secreted inducible nitric oxide synthase and M2 macrophage-secreted arginase-1 in the retina, which led to significant decreases in the expression levels of tumour necrosis factor-α (TNF-α). ω3-PUFA supplementation alone also resulted in significantly reduced expression of interleukin-18 (IL-18). ω3-PUFA + timolol treatment had no effect on the expression level of any of the aforementioned mediators in the retina. Supplementation with ω3-PUFAs has neuroprotective effect in the retinas of DBA/2J mice that is enhanced when combined with timolol eye drops. The continued inflammation following ω3-PUFAs + timolol treatment suggests that downregulation of IL-18 and TNF-α may not be the only factors involved in ω3-PUFA-mediated neuroprotection in the retina.

A pyogenic granuloma (PG) is a rapidly growing benign vascular tumor that can be found on the skin or subcutaneous tissue. While some pyogenic granulomas may resolve spontaneously, most have a tendency to bleed easily and require treatment. Current therapeutic modalities include topical imiquimod, cryotherapy, electrodessication, curettage, excision, laser therapy, sclerotherapy, and microembolization. We report a recalcitrant case of chronic pyogenic granuloma occurring on the scalp of a healthy young male which was unresponsive to conventional surgical and non-surgical modalities. Ultimately, aggressive laser therapy, intralesional triamcinolone acetonide injections, and topical timolol application led to complete resolution and healing.

OBJETIVO: determinar a prevalência de sinais e sintomas de doença da superfície ocular (OSD) em pacientes em uso crônico de hipotensores oculares tópicos. MÉTODOS: Neste estudo transversal, foram recrutados 40 pacientes consecutivos, provenientes do ambulatório de glaucoma de um hospital público localizado no Rio de Janeiro, Brasil. Os mesmos deveriam apresentar: idade maior ou igual a 18 anos, diagnóstico de hipertensão ocular ou glaucoma primário de ângulo aberto e deveriam estar em uso da mesma terapia hipotensora ocular há pelo menos seis meses. Foram considerados: sexo, idade, medicação utilizada e duração do tratamento. Todos os pacientes foram submetidos à avaliação da superfície ocular que incluiu: entrevista por meio do questionário Ocular Surface Disease Index® (OSDI®), tempo de rotura do filme lacrimal, biomicroscopia, avaliação da superfície ocular com fluoresceína e com rosa Bengala. RESULTADOS: A média de pontuação do OSDI® foi 24,6 ± 20,7. A maioria dos pacientes (67,5%) apresentou uma pontuação anormal no questionário do OSDI®. Em 25% dos pacientes, a pontuação foi compatível com sintomas leves, em 12,5% com sintomas moderados e em 30% com sintomas graves. Blefarite e ceratite ponteada foram diagnosticadas em 42,5% e 20% dos pacientes respectivamente. Instabilidade do filme lacrimal foi observada em 75% dos pacientes, enquanto que alteração da superfície ocular foi evidenciada pelo teste de rosa bengala em 35% dos pacientes. Foi encontrada correlação positiva (r=0,4) estatisticamente significativa (p=0,01) entre a pontuação do OSDI® e o tempo de duração do tratamento com hipotensores oculares tópicos. CONCLUSÃO: Pacientes em uso crônico de hipotensores oculares tópicos apresentam alta prevalência de sinais e sintomas de OSD. Existe correlação significativa entre a duração do tratamento e a gravidade dos sintomas de OSD.
PURPOSE: To determine the prevalence of signs and symptoms of ocular surface disease (OSD) in patients using topical intraocular pressure-lowering therapy. METHODS: In this cross-sectional study, 40 patients were consecutively recruited from the glaucoma clinic of a public hospital located in Rio de Janeiro, Brazil. Eligible patients were 18 years of age or older, with primary open-angle glaucoma or ocular hypertension and on the same topical ocular therapy for at least 6 months. The following data were considered: sex, age, medication history and number of years on topical intraocular pressure-lowering therapy. All patients underwent an evaluation of the ocular surface which included: an interview using the Ocular Surface Disease Index® (OSDI®) questionnaire, break-up time, biomicroscopy, fluorescein corneal staining and rose Bengal ocular surface staining. RESULTS: The mean OSDI® score was 24.6 ± 20.7. Most patients (67.5%) had an abnormal score on the OSDI® questionnaire. In 25% of patients, the score was consistent with mild symptoms, 12.5% with moderate symptoms and 30% with severe symptoms. Blepharitis and punctate keratitis were diagnosed in 42.5% and 20% of patients respectively. Tear film instability was observed in 75% of patients and ocular surface staining with rose Bengal in 35%. A positive statistically significant correlation (r=0.4; p=0.01) was found between OSDI® scores and the duration of topical intraocular pressure-lowering therapy. CONCLUSION: Patients with primary open-angle glaucoma or ocular hypertension on topical intraocular pressure-lowering therapy have high prevalence of OSD. Longer duration since diagnosis is significantly correlated with worsening of OSD symptoms.

O objetivo é relatar o caso de uma paciente de 33 anos, que veio ao Pronto Socorro de Oftalmologia apresentando queixa de redução da acuidade visual à esquerda, de caráter insidioso e progressivo, há dois anos. Ao exame oftalmológico, apresentava ingurgitamento dos vasos da conjuntiva bulbar, pressão intraocular muito elevada e nervo óptico com escavação total à esquerda. Foi submetida à campimetria computadorizada 24:2 WW e SITA-SWAP do olho direito, ambas com resultados dentro da normalidade. As tomografias de crânio e órbitas, bem como ultrassonografia com doppler do globo ocular, artérias oftálmicas e veias supraorbitárias não apresentavam anormalidades. Diante disso, aventou-se a hipótese diagnóstica de hipertensão venosa episcleral idiopática, um diagnóstico de exclusão, visto que patologias intracranianas e intraorbitárias haviam sido excluídas. Paciente foi tratada clinicamente com colírios hipotensores, com redução importante da pressão intraocular à esquerda, porém não o suficiente, evoluindo para trabeculectomia.
The objective is to report a 33 year old female who came to the emergency room of Ophthalmology complaining of reduced visual acuity on the left eye, in a progressive and insidious way, about two years ago. In the ophthalmological examination, she presented dilated tortuous vessels in her left bulbar conjunctiva, very high intraocular pressure and increased cupping of the optic disc. SITA-SWAP and 24:2 computed perimetry were performed on the right eye, both within normal limits. CT scans of the skull and orbits, and ultrasonography of the eyeball and doppler of the ophthalmic artery and the supra-orbital veins had no abnormalities. Thus, it was suggested the possibility of idiopathic elevated episcleral venous pressure, an exclusion diagnosis, since intra-cranial and intraorbital pathologies were excluded. The patient was treated medically with hypotensive eyedrops, with significant reduction of intraocular pressure on the left eye, but not enough, evolving to trabeculectomy.

PURPOSE: To characterize the microbead-induced ocular hypertension (OHT) mouse model and investigate its potential use for preclinical screening and evaluation of ocular hypotensive agents, we tested the model's responses to major antiglaucoma drugs. METHODS: Adult C57BL/6J mice were induced to develop OHT unilaterally by intracameral injection of microbeads. The effects of the most commonly used ocular hypotensive drugs, including timolol, brimonidine, brinzolamide, pilocarpine, and latanoprost, on IOP and glaucomatous neural damage were evaluated. Degeneration of retinal ganglion cells (RGCs) and optic nerve axons were quantitatively assessed using immunofluorescence labeling and histochemistry. Thickness of the ganglion cell complex (GCC) was also assessed with spectral-domain optical coherence tomography (SD-OCT). RESULTS: A microbead-induced OHT model promptly responded to drugs, such as timolol, brimonidine, and brinzolamide, that lower IOP through suppressing aqueous humor production and showed improved RGC and axon survival as compared to vehicle controls. Accordingly, SD-OCT detected significantly less reduction of GCC thickness in mice treated with all three aqueous production suppressants as compared to the vehicle contol-treated group. In contrast, drugs that increase aqueous outflow, such as pilocarpine and latanoprost, failed to decrease IOP in the microbead-induced OHT mice. CONCLUSIONS: Microbead-induced OHT mice carry dysfunctional aqueous outflow facility and therefore offer a unique model that allows selective screening of aqueous production suppressant antiglaucoma drugs or for studying the mechanisms regulating aqueous humor production. Our data set the stage for using GCC thickness assessed by SD-OCT as an imaging biomarker for noninvasive tracking of neuronal benefits of glaucoma therapy in this model.

We present a case of a 63-year-old woman who presented to an ED with bifrontal headache, nausea and vomiting and reduced visual acuity. Examination revealed bilateral elevated intraocular pressures, corneal haze, shallow anterior chambers and poorly reactive, mid-dilated pupils. Diagnosis was made of simultaneous bilateral acute angle closure glaucoma. A complete drug history revealed that she had been using an over-the-counter cold and flu remedy whose active ingredients included atropa belladonna, an herb with anticholinergic properties. It is likely that drug-induced dilatation of the individual's pupils precipitated this angle closure emergency. In the report we discuss the risk factors for angle closure glaucoma, and review the local and systemic drugs known to trigger this sight-threatening emergency.

The clinical efficacy of rituximab therapy in systemic mucosa-associated lymphoid tissue (MALT) lymphoma with both periocular and intraocular involvement is described. Ophthalmic examination and radiologic imaging demonstrated tumor with bilateral periorbital, lacrimal, and subconjunctival infiltration, a pseudohypopyon in one eye, and extensive systemic lymph node involvement. Lymph node biopsy confirmed the pathologic findings of a low-grade MALT lymphoma. The patient had a complete remission within 3 months of starting rituximab therapy. A recurrence 6 months later remitted with a second round of rituximab therapy and the patient remained tumor-free at 1 year.

AIM: The present study was designed to evaluate the intraocular pressure (IOP)-lowering activity of topical application of the aqueous extract of Aegle marmelos fruit in experimental animal models. MATERIALS AND METHODS: New Zealand white rabbits with normal and experimentally elevated IOP using water loading and steroid-induced models were included in this study. The IOP-lowering effect of A. marmelos fruit extract in rabbits with experimentally elevated IOP was also compared with that of timolol 0.25%. RESULTS: In rabbits with normal IOP, the A. marmelos fruit extract at a concentration of 1% showed the maximum IOP-lowering effect with 22.81% reduction from baseline IOP. The maximum IOP reduction achieved in water loading and steroid-induced models with the same concentration of A. marmelos was 27.57 and 28.41% from baseline, respectively. The efficacy was comparable to that of timolol after 45 min of water loading in the water loading model, and during the first 2 h of treatment in the steroid-induced model. CONCLUSION: A. marmelos fruit extract showed significant IOP-lowering activity in experimental animal models.

PURPOSE: Evaluation of oculohypotensive activity of single drop application of aqueous extract of Foeniculum vulgare in experimental models of glaucoma. METHODS: The evaluation of oculohypotensive activity of Foeniculum vulgare was done in rabbits with normal intraocular pressure (IOP) and with experimentally elevated IOP. The experimental increase in IOP was achieved using water loading and steroid induced glaucoma models. RESULTS: The aqueous seed extract of Foeniculum vulgare exhibited 17.49, 21.16 and 22.03% reduction of intraocular pressure (IOP) in normotensive rabbits at 0.3%, 0.6% and 1.2% (w/v) concentrations respectively. The 0.6% concentration was further evaluated in acute and chronic models of glaucoma. A maximum mean difference of 31.20% was observed between vehicle treated and extract treated eyes in water loading model while a maximum mean IOP lowering of 31.29% was observed in steroid induced model of glaucoma. CONCLUSIONS: The aqueous extract of Foeniculum vulgare possesses significant oculohypotensive activity, which was found to be comparable to that of timolol. Further investigations into the mechanism of action, possible toxicity and human clinical trials are warranted before the Foeniculum vulgare finds place in the arsenal of antiglaucoma drugs prescribed by physicians.

Intraocular pressure (IOP)-lowering effects of investigational antiglaucoma drugs often need comparison with existing drugs, but detailed data showing comparative efficacy of antiglaucoma drugs with different mechanism of action has not been reported so far. This study was designed to establish baseline information of the IOP-lowering effect of three currently used antiglaucoma drugs in three experimental models in rabbits, so that they act as a benchmark for the efficacy evaluation of the future experimental antiglaucoma drugs. The IOP-lowering effect of single-drop application of pilocarpine, timolol and latanoprost was studied in normotensive, water loading and steroid-induced models of glaucoma in rabbits. The noncontact tonometer was used for the first time to estimate IOP in rabbits. The peak IOP-lowering effect of pilocarpine, timolol and latanoprost in normotensive rabbit eye was 18.23%, 20% and 22.56%, respectively. In water-loading model, the maximum protection against the rise in IOP was shown by latanoprost (40.27%), followed by timolol (31.39%) and pilocarpine (28.91%). In steroid-pretreated rabbit eyes, peak IOP-lowering effects of pilocarpine, timolol and latanoprost were 25.65%, 34.21% and 35.06%, respectively. Therefore, the latanoprost was found to be most effective in all three models followed by timolol and pilocarpine. The results of this study can be used for future preclinical investigations for the assessment of IOP-lowering activity of potential antiglaucoma drugs.

PURPOSE: To evaluate the association between open-angle glaucoma (termed glaucoma) and 9-year mortality in an older population-based cohort. DESIGN: Population-based cohort. PARTICIPANTS: Three thousand six hundred fifty-four persons aged 49 to 97 years (82.4% of the eligible population), residents of the Blue Mountains, west of Sydney, Australia. METHODS: At baseline (1992-1994), glaucoma was diagnosed from congruous typical glaucomatous visual field changes (full-threshold fields) and optic disc cupping (stereo-optic disc photography). Demographic information from baseline participants was matched with the Australian National Death Index data (December 2001) to obtain the number and causes of deaths. Cox proportional hazards regression analysis, controlling for age, male gender, diabetes, hypertension, heart disease, stroke, use of oral beta-blockers, current smoking history, alcohol use, myopia, and nuclear cataract were performed to assess hazard ratios for cardiovascular mortality. Adjustments for all-cause mortality also included history of cancer. MAIN OUTCOME MEASURES: Cardiovascular and all-cause mortality. RESULTS: At baseline, glaucoma was diagnosed in 108 participants (3.0%). Of 873 deaths (23.9%) before January, 2002, 312 people (8.5%) died of cardiovascular events. The age-standardized all-cause mortality was 24.3% in persons with and 23.8% in those without glaucoma, whereas cardiovascular mortality was 14.6% in persons with and 8.4% in those without glaucoma. After multivariate adjustment, those with glaucoma had a nonsignificant increased risk of cardiovascular death (relative risk [RR], 1.46; 95% confidence interval [CI], 0.95-2.23). Increased cardiovascular mortality was observed mainly in glaucoma patients aged <75 years (RR, 2.78; 95% CI, 1.20-6.47). Further stratified analyses showed that cardiovascular mortality was higher among those with previously diagnosed glaucoma (RR, 1.85; 95% CI, 1.12-3.04), particularly in those also treated with topical timolol (RR, 2.14; 95% CI, 1.18-3.89). CONCLUSIONS: Findings from the Blue Mountains Eye Study demonstrate an increased cardiovascular mortality in persons with previously diagnosed glaucoma. There was a suggestion of higher cardiovascular mortality in glaucoma patients using topical timolol that merits further study.

The aim of this randomized, prospective, masked clinical study has been to verify the influence of a non-steroidal anti-inflammatory drug ophthalmic solution on intraocular pressure reduction induced by 0.5% timolol and 0.005% latanoprost eyedrops in patients affected by primary open-angle glaucoma. Thirty-two glaucomatous patients, compensated with 0.5% timolol, were randomized into two study groups (A and B). Timolol was continued for the first 2 weeks in all subjects. On the 15th day, in both groups timolol was replaced by latanoprost, and this regimen lasted up to the end of the follow-up (8 weeks). At the beginning of the 2nd week of the study, group A additionally started a 5-week therapy with topical 0.1% diclofenac; during the same period, group B received placebo eyedrops with identical modalities. Intraocular pressure was recorded at 7-day intervals during the first 7 weeks and at the 10th week. Non-steroidal anti-inflammatory drug and placebo did not modify the effect of timolol on intraocular pressure. In both groups, latanoprost induced a significant decrease in intraocular pressure. Diclofenac-treated patients exhibited a marked fall in intraocular pressure (p<0.01), whereas in placebo-treated patients, this diminution was less noticeable (p<0.05). After diclofenac withdrawal, in group A intraocular pressure significantly increased (p<0.01), remaining approximately at the same level up to the end of the study. In group B, at the same checks no significant variations in intraocular pressure occurred. In primary open-angle glaucoma patients, diclofenac significantly enhances the hypotensive effect of latanoprost, without influence on timolol efficacy. Because non-steroidal anti-inflammatory drugs are widely employed in medical practice, supplementary ophthalmologic checks should be scheduled during the co-administration of these compounds and prostaglandin analogues.

OBJECTIVE: To investigate the relationship between drainage angle configuration with untreated intraocular pressure (IOP) and optic disc cupping in subjects with chronic angle-closure glaucoma (CACG). DESIGN: Prospective, observational study. PARTICIPANTS: Two hundred seventy-five Asian subjects with CACG who participated in a randomized controlled trial that investigated the IOP-reducing effect of latanoprost and timolol. METHODS: Chronic angle-closure glaucoma was defined as the presence of glaucomatous optic neuropathy (with or without a visual field defect), an anterior chamber angle in which the pigmented trabecular meshwork was not visible for at least 180 degrees on gonioscopy, and evidence of peripheral anterior synechiae (PAS) in association with elevated IOP of 21 mmHg or more. Static and dynamic gonioscopy were performed, the angles were graded in each quadrant according to the Shaffer scheme, and the number of clock hours of PAS was recorded. The untreated IOP and vertical cup-to-disc ratio were correlated with mean angle width and extent of PAS. MAIN OUTCOME MEASURES: Mean angle width, clock hours of PAS, IOP, and vertical cup-to-disc ratio. RESULTS: Most subjects were female (75%), and the mean age was 62.9+/-9.4 years. The mean angle width was 0.77+/-0.53 and the mean number of clock hours of PAS was 4.77+/-3.2 hours. Untreated IOP correlated with angle width (r = -0.23; P<0.001) and clock hours of PAS (r = 0.22; P<0.001). Vertical cup-to-disc ratio also correlated with angle width (r = -0.17; P = 0.004) and PAS (r = 0.28; P<0.001). Performing a multiple linear regression using baseline IOP as the outcome variable with age, gender, clock hours of PAS, and angle width as predictors, there was a 0.39-mmHg (95% confidence interval, 0.15-0.63) increase in baseline untreated IOP for each unit increase in clock hours of PAS (P = 0.002). CONCLUSIONS: In subjects with CACG, the extent of PAS and a narrower width of the drainage angle were associated with higher untreated IOP and a larger vertical cup-to-disc ratio.

PURPOSE: The diurnal efficacy and safety of the fixed combinations of latanoprost/timolol given once daily vs dorzolamide/timolol given twice daily in primary open-angle glaucoma or ocular hypertensive patients. DESIGN: A double-masked, two-centre, crossover comparison. RESULTS: In 33 patients, the mean diurnal IOP (0800-2000, measured every 2 h) for latanoprost/timolol fixed combination was 17.3+/-2.2 mmHg and for dorzolamide/timolol, the fixed combination was 17.0+/-2.0 mmHg (P = 0.36). Additionally, there was no statistical difference for individual time points following a Bonferroni correction. A bitter taste was found more frequently with the dorzolamide/timolol fixed combination (n = 6) than the latanoprost/timolol fixed combination (n = 0) (P = 0.040), while the latanoprost/timolol fixed combination demonstrated more conjunctival hyperaemia (n = 9) than the dorzolamide/timolol fixed combination (n = 2) (P = 0.045). One patient was discontinued early from the dorzolamide/timolol fixed combination due to elevated IOP. CONCLUSION: This study suggests that the daytime diurnal IOP is not statistically different between the dorzolamide/timolol fixed combination and latanoprost/timolol fixed combination in primary open-angle glaucoma and ocular hypertensive patients.

Seventy patients with normal pressure glaucoma (NPG) were treated on the differential basis with respect to a pathogenetic disease type. The suggested complex therapy of the ischemic variation improves both the microcirculation in the optic nerve disk (OND) by administering different-effect drugs in long courses and the systemic hemodynamics (practitioners of needed skills are involved). The use of local antihypertensive drug to reduce the intraocular pressure to an individual tolerable value is important in the treatment of patients with tension-ischemic glaucoma. The process stabilized in 75.8 +/- 3.9% of patients in the main group and in 47 +/- 8.5% of patients in the control group (p < 0.05) after a follow-up of up to 2.5 years.

Previous studies have evaluated the efficacy of several interventions to decrease the progression of myopia. These include devices that alter the perception of the visual environment and pharmacological treatments. There is no conclusive evidence thus far that alteration of the pattern of spectacle wear, bifocals, ocular hypotensives, or contact lenses retards the progression of myopia. Several randomised clinical trials have demonstrated that the rate of progression of myopia is lower in children given atropine eye drops than those given placebo. However, atropine is associated with short term side effects such as photophobia and possible long term adverse events including light induced retinal damage and cataract formation. Other more selective antimuscarinic agents such as pirenzipine are presently being evaluated. Further well conducted randomised clinical trials with large sample sizes and adequate follow up designed to evaluate treatments to retard the progression of myopia should be conducted, since the identification of an effective intervention may have a greater public health impact on the burden and morbidity from myopia than the few treatments currently available.
